Subject: [PATCH 001/311] fix: skip spatial shape check when gpu_augmentations
 handle cropping

When gpu_augmentations include a spatial crop (e.g. BatchedCenterSpatialCropd),
the output shape intentionally differs from z_window_size/yx_patch_size.
The validation was raising a false ValueError for configs like UNeXt2
(z_window=20 read, gpu crop to 15) and CellDiff (z_window=13 read, crop to 8).

Subject: [PATCH 002/311] chore: tune UNeXt2 SEC61B config for GPU utilization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

z_window_size 15→20: restores the 5-slice Z margin for affine augmentation
(20 read → 15 after GPU center crop), matching the original VSCyto3D
finetune_3d.py pipeline.

batch_size 8→64 with num_samples 2→4: each GPU now processes 16 samples
(~13 GB VRAM) instead of 2 (~2 GB), reducing GPU idle time from ~97% to
~84%. LR scaled by sqrt(8) for Adam (0.0002→0.0006).

SLURM: mem-per-cpu 12G→20G for /dev/shm mmap buffer headroom. Removed
--ckpt_path for fresh training with new hyperparameters.

Subject: [PATCH 003/311] fix: correct CellDiff SEC61B config for two-stage z
 crop and exact val crop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

z_window 8→13 with spatial_size [13,624,624]: provides 5-slice Z margin
(13→8 after GPU center crop) and 112px YX margin (624→512) for affine
augmentation artifacts, matching the UNeXt2 two-stage crop strategy.

batch_size 4→8: doubles throughput without VRAM pressure.

Phase3D normalization: median/iqr→mean/std to match UNeXt2 and the
original VSCyto3D pipeline.

val_gpu_augmentations: DivisibleCropd→BatchedCenterSpatialCropd because
CellDiff's ViT requires exact input_spatial_size [8,512,512] (fixed
positional embeddings), not just divisible dimensions.

max_epochs 200→10: initial smoke-test run before scaling up.

Subject: [PATCH 008/311] fix: tune UNeXt2 SEC61B lr, batch_size, and val crop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reduce lr 0.0006→0.0004 and batch_size 64→32 to fit within node RAM
budget. Fix val_gpu_augmentations: BatchedDivisibleCropd with k=
[1,64,64] left Z at 20 slices (no Z reduction); replace with
BatchedCenterSpatialCropd roi_size=[15,384,384] to match the model's
expected input.

Subject: [PATCH 010/311] fix: train UNeXt2 from scratch with corrected config

Previous checkpoints used wrong val aug (BatchedDivisibleCropd,
no Z reduction) and different lr/batch_size. Resuming would mix
incompatible training dynamics. Start fresh with corrected config.

 num_workers to 4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Single GPU gave 10,816 steps/epoch (2h) due to 32 overlapping
z-windows per FOV × 338 FOVs. With 4-GPU DDP at batch=2/GPU, steps
drop to 2,704/epoch (~31 min). mmap buffer is OS-shared so RAM stays
flat. Reduce num_workers 8→4 (4 workers × 4 ranks = 32 processes
for 32 CPUs).

Subject: [PATCH 012/311] fix: add padding_mode to BatchedRandAffined
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Kornia 0.8.x hard-codes padding_mode='zeros' in RandomAffine3D.
Add _PaddedRandomAffine3D subclass that overrides apply_transform
to pass the user-specified mode to warp_affine3d (which already
supports it).

Expose padding_mode='border'|'reflection' in BatchedRandAffined
for configs where crop/output ratio < √2 and the oversized border
cannot absorb large rotations without zero-corner artifacts.

Subject: [PATCH 014/311] fix: load DynacellFlowMatching checkpoint via model
 init_args

LightningCLI._parse_ckpt_path merges checkpoint hyper_parameters back
into the config before class instantiation, so a checkpoint trained
with predict_method='generate' would silently override the user's
predict_method='sliding_window' in the YAML config.

Fix by mirroring DynacellUNet: add ckpt_path to __init__, load state
dict there directly, and exclude it (along with all predict-time params)
from save_hyperparameters. With no top-level ckpt_path in the config,
_parse_ckpt_path is never triggered.

Move ckpt_path and output_store from the predict_gpu.yml recipe into
the per-experiment predict config; recipes stay as pure templates.
Add sec61b/predict_celldiff.yml as the canonical SEC61B CellDiff
predict config.

Subject: [PATCH 015/311] fix: make user config take precedence over checkpoint
 hparams in CLI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

LightningCLI._parse_ckpt_path applies checkpoint hyper_parameters as
the highest-priority config layer, overriding values the user explicitly
set in the YAML. The correct hierarchy is:
  base-class defaults → checkpoint hparams → user config

Snapshot model init_args before the checkpoint merge and restore them
after, so any value present in the user's config always wins.

Subject: [PATCH 016/311] feat: add safe_crop_size scale clamping to
 BatchedRandAffined
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When rotation + zoom-out combine, the backward-warp footprint can
exceed the source crop, creating zero-corner artifacts. The new
safe_crop_size parameter computes a per-sample scale floor from the
sampled rotation angle: s_min = coverage * k(θ) * D / S, where
k = |cos θ| + |sin θ|. safe_crop_coverage (default 1.0) relaxes the
constraint — 0.9 allows small corners as extra augmentation while
eliminating the worst ~30% of artifacts.

Also removes padding_mode=border from CellDiff config (the scale
clamping makes it unnecessary).

+- Ruff config is centralized in the root `pyproject.toml` only. Sub-packages must NOT have their own `[tool.ruff.*]` sections. Ruff does not inherit config — any `[tool.ruff.*]` in a sub-package silently overrides the entire root config (including `lint.select`, `per-file-ignores`, etc.).
+- Run `uvx prek run --files {files_you_edited}` (unless the change was simple) and fix typing and linting errors. Use `# type: ignore` as needed. The precommit will give you type errors which is useful — especially to know if you have incorrect code — but for many minor changes it's better to do this after testing. Use a subagent to apply complex fixes.

-  Ruff does not inherit config — any `[tool.ruff.*]` in a sub-package
-  silently overrides the entire root config (including `lint.select`,
-  `per-file-ignores`, etc.).
 - Docstrings use **numpy style** (`convention = "numpy"`).
 - Lint rules: `D, E, F, I, NPY, PD, W`.
 - `D` rules are ignored in `**/tests/**` and notebooks.
 - Format: double quotes, spaces, 120 char line length.
-- Prefer {file}_test.py in the same directory as {file}.py, unless there are import issues, in which case use tests/...

-### Prefer Raising Errors
-In general, prefer raising errors instead of silently catching them. Errors are good and warn us of issues in the script. For example, prefer `value = my_dictionary['key']` over `value = my_dictionary.get('key')` since the former will raise a `KeyError` to signal that the underlying data is not behaving as expected.

 Only catch errors when there is a good reason to do so: for example, catching HTTP errors in order to retry a request.
 
 If you find yourself writing an if statement, fallback, or except statement designed to avoid errors, ask yourself if it would be better to raise the error as a signal to the user.

-### Use Real Integration Tests
-Tests should directly *import* the actual code we are trying to test. For example, if you are trying to test `my_function` on some sample data, your test should directly import `my_function` and run it on the sample data.

+Tests should directly *import* the actual code we are trying to test. For example, if you are trying to test `my_function` on some sample data, your test should directly import `my_function` and run it on the sample data.

 Ask yourself if your test is actually covering the true function.

+### Coding Philosophy
 
-## Coding
+#### 1. Think Before Coding
 
-1. Think Before Coding
 Don't assume. Don't hide confusion. Surface tradeoffs.
 
 Before implementing:
+- State your assumptions explicitly. If uncertain, ask.
+- If multiple interpretations exist, present them — don't pick silently.
+- If a simpler approach exists, say so. Push back when warranted.
+- If something is unclear, stop. Name what's confusing. Ask.

-If a simpler approach exists, say so. Push back when warranted.
-If something is unclear, stop. Name what's confusing. Ask.
-2. Simplicity First
 Minimum code that solves the problem. Nothing speculative.
 
-No features beyond what was asked.
-No abstractions for single-use code.
-No "flexibility" or "configurability" that wasn't requested.
-No error handling for impossible scenarios.
-If you write 200 lines and it could be 50, rewrite it.
-Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.

-3. Surgical Changes
 Touch only what you must. Clean up only your own mess.
 
 When editing existing code:
+- Don't "improve" adjacent code, comments, or formatting.

+- If you notice unrelated dead code, mention it — don't delete it.

 When your changes create orphans:
+- Remove imports/variables/functions that YOUR changes made unused.

+#### 4. Goal-Driven Execution
 
-4. Goal-Driven Execution
 Define success criteria. Loop until verified.
 
 Transform tasks into verifiable goals:
+- "Add validation" → "Write tests for invalid inputs, then make them pass"
+- "Fix the bug" → "Write a test that reproduces it, then make it pass"
+- "Refactor X" → "Ensure tests pass before and after"
 
-"Add validation" → "Write tests for invalid inputs, then make them pass"
-"Fix the bug" → "Write a test that reproduces it, then make it pass"
-"Refactor X" → "Ensure tests pass before and after"
 For multi-step tasks, state a brief plan:
-
 1. [Step] → verify: [check]
 2. [Step] → verify: [check]
-3. [Step] → verify: [check]
+
 Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.

and belong in the dynacell-paper repo. The hcs_sec61b_3d data recipe
hardcodes HPC paths. All preserved on preserve/sec61b-configs branch.

From 8f0adb9481cce2a89243963c3523dca263ce59f0 Mon Sep 17 00:00:00 2001
From: Alexandr Kalinin <alxndrkalinin@users.noreply.github.com>
Date: Tue, 14 Apr 2026 14:06:46 -0700
Subject: [PATCH 022/311] refactor: move configs from examples/configs/ to
 configs/
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three-layer config model:
- configs/recipes/ — reusable fragments (model, trainer, data, modes)
- configs/examples/ — generic fit/predict pair per model family

Fix base: references (../recipes/ → ../../recipes/), scrub hardcoded
SEC61B paths from celldiff predict, add missing ckpt_path to fnet3d
and unetvit3d predict, change preload default to false in generic
recipe, update test config discovery path and __main__ docstring.

Subject: [PATCH 023/311] feat: add generic UNeXt2 example configs

UNeXt2 had a model recipe but no generic example. Adds fit.yml and
predict.yml following the same pattern as fnet3d/unetvit3d/celldiff
examples. Config discovery test now finds 8 leaf configs.

Subject: [PATCH 024/311] feat: add data schemas and path-based loaders

Absorb dataset manifest schemas from dynacell-paper and add new
benchmark collection and spec schemas per VISCY_HANDOFF.md.

- manifests.py: DatasetManifest, TargetConfig, VoxelSpacing,
  StoreLocations, SplitDefinition + load_manifest, load_splits,
  get_target
- collections.py: Provenance, ChannelEntry, CollectionExperiment,
  BenchmarkCollection + load_collection
- specs.py: BenchmarkSpec + load_benchmark_spec

No registry dict, no import-time side effects. Callers pass paths
explicitly. Add pydantic>=2 and omegaconf to base dependencies.

Subject: [PATCH 025/311] refactor: reuse ChannelEntry from viscy_data, extract
 YAML loader

- Reuse viscy_data.collection.ChannelEntry instead of duplicating it
- Extract shared OmegaConf+Pydantic loading to _yaml.load_yaml()
- Keep Provenance local (stricter than viscy_data version: required
  created_at/created_by for benchmark traceability)

Subject: [PATCH 026/311] feat: absorb reporting module from dynacell-paper

Migrate tables, figures, and Hydra CLI entry point for benchmark
reporting. tables.py is pure pandas, figures.py preserves Agg backend
ordering, cli.py uses parents[3] for config resolution.

Tests use module-level pytest.importorskip() for pandas/matplotlib
so they skip gracefully without those deps installed.

Subject: [PATCH 027/311] feat: absorb preprocess utilities from dynacell-paper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Migrate rewrite_zarr() and load_preprocess_config() — the clearly
reusable, dependency-light preprocess helpers. Dataset-specific
utilities (selection, segmentation, workflow) remain in dynacell-paper.

Subject: [PATCH 028/311] feat: expand CLI with evaluate/report subcommand
 routing

Lightning subcommands (fit, predict, test, validate) delegate to
viscy_utils.cli.main(). Hydra subcommands (evaluate, report) lazily
import their entry points. ModuleNotFoundError prints an install hint
for the missing extra instead of a raw traceback.

Subject: [PATCH 029/311] feat: absorb evaluation module from dynacell-paper

Full evaluation pipeline: pixel metrics (PCC, SSIM, NRMSE, PSNR),
segmentation metrics (Dice, IoU), feature metrics (DINOv3, DynaCLR FID),
spectral PCC subpackage, and Hydra CLI entry point.

Heavy deps (segmenter_model_zoo, aicssegmentation, cubic, microssim,
transformers, dynaclr, skimage) gated with try/except ImportError.
Pipeline imports segmentation/utils lazily inside functions so
`import dynacell.evaluation.pipeline` succeeds without heavy deps.

eval.yaml uses OmegaConf ??? markers for all required fields so
running without overrides gives MissingMandatoryValue, not AttributeError.

Subject: [PATCH 030/311] chore: add optional dependency extras for eval,
 report, preprocess

- eval: all deps for dynacell evaluate (segmentation, metrics, cubic,
  transformers, dynaclr, etc.)
- report: pandas + matplotlib + hydra for dynacell report
- preprocess: iohub + tqdm for zarr rewriting utilities

Subject: [PATCH 031/311] fix: pin microssim to git main for torch>=2.10 compat

PyPI microssim 0.0.3 pins torch<=2.9.1 which conflicts with
viscy-data's torch>=2.10. Main branch (8bccb17d) already bumped
to torch<=2.11.0 but hasn't been released yet. Pin to git main
until 0.0.4 is published.

From 038e8d8026ee9168114ce21eee43c214686843fc Mon Sep 17 00:00:00 2001

Subject: [PATCH 033/311] =?UTF-8?q?fix:=20address=20Copilot=20review=20?=
 =?UTF-8?q?=E2=80=94=20argv=20bug,=20stale=20docstring,=20SHA=20pin?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix sys.argv[0] bug in CLI error message: capture subcommand
  before mutating argv so the hint says "dynacell evaluate" not
  "dynacell dynacell"
- Update tables.py docstring: dynacell_paper → dynacell
- Add OOM caveat to rewrite_zarr docstring
- Pin microssim to commit SHA (8bccb17d) instead of @main

From: Alexandr Kalinin <alxndrkalinin@users.noreply.github.com>

Subject: [PATCH 034/311] fix: address review findings in evaluation,
 reporting, and preprocess
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hydra config_path used parents[N] resolution which breaks after
pip install (wheel has no top-level configs/ directory). Moved
configs into the package (_configs/) so they ship with the wheel
and use relative config_path instead.

Also fixes: zarr stores opened without context managers in
spectral_pcc, assert→ValueError for runtime validation, use_gpu
flag not forwarded to compute_pixel_metrics/segmentation, bar
chart misalignment when models expose different metrics, corr_coef
returning 0.0 instead of NaN for zero-variance input, division by
zero in formatting.py, hardcoded HPC path in diagnostic_real.yaml,
unnecessary try/except in preprocess/config.py, missing torch_ssim
module docstring.

Subject: [PATCH 035/311] fix: skip ckpt_path hparam snapshot during fit
 subcommand
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The init_args snapshot/restore in _parse_ckpt_path was applied to
all subcommands, overwriting checkpoint hparams with parser defaults
during 'fit --ckpt_path' resume. This silently replaced saved lr,
architecture, and model_config with default values — breaking
training resumption for all apps using VisCyCLI.

Now the snapshot only applies during predict/test/validate where
user config should take precedence over stale checkpoint values.

Subject: [PATCH 036/311] docs: clarify ckpt_path is inference-only (no
 optimizer state)

The docstring didn't mention that ckpt_path loads weights only.
Users resuming training should use Lightning's --ckpt_path flag
instead, which restores optimizer, epoch, and scheduler state.

Subject: [PATCH 038/311] refactor: make dynacell __init__.py lazy to decouple
 data from engine

Importing dynacell.data previously triggered dynacell.engine which
pulled in torch, lightning, monai, and all viscy packages. This made
lightweight operations (CLI data commands, paper scripts, tests) pay
the full ML stack startup cost.

Use __getattr__ to defer DynacellUNet and DynacellFlowMatching
imports until first access. Public API unchanged: from dynacell import
DynacellUNet still works.

Subject: [PATCH 039/311] fix: correct PCC bias in corr_coef and use absolute
 imports
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

corr_coef used population mean (N) in the numerator but Bessel-
corrected std (N-1) in the denominator, giving PCC × (N-1)/N — a
systematic ~1% downward bias for typical patch sizes. Use
std(correction=0) for consistent N-based computation.

Also switches relative imports to absolute per CLAUDE.md.

The cache path returned np.load(...) ndarrays while the fresh-
compute path returned Python lists. Callers checking isinstance
or calling list methods would behave differently depending on
whether the cache existed. Now both paths return lists.

Subject: [PATCH 042/311] fix: warn when safe_crop_size used with X/Y rotations

_compute_scale_floor only accounts for Z-axis rotation. Non-zero
X/Y rotations produce an underestimated scale floor that may not
prevent zero-corner artifacts. Log a warning so users know the
coverage guarantee is approximate in that case.

- Move numpy/evaluate_segmentations/pytest imports to module level

Subject: [PATCH 046/311] fix: add __init__.py to Hydra _configs directories

Hydra's pkg config search requires config directories to be Python
packages. Without __init__.py, installed packages fail with
MissingConfigException when trying to resolve config_path="_configs".

Subject: [PATCH 047/311] fix: move safe_crop_size X/Y rotation warning to
 __init__

The warning was firing on every __call__ (i.e. every training batch),
flooding the log with thousands of identical messages. Move to
__init__ where it fires once at construction time by checking the
configured rotation ranges rather than sampled angles.

Subject: [PATCH 049/311] feat: add opt-in validation loss for CellDiff
 flow-matching
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Flow-matching previously had no validation loss — only ODE-based sample
generation at epoch end. This adds a compute_validation_loss flag
(default False) that, when enabled, runs the same flow-matching forward
pass on every validation batch and logs loss/val/<idx> per loader plus
an aggregated loss/validate at epoch end. Generation logging is
unchanged and still works alongside the new loss path.

Overhead is modest (~4-5% per epoch on SEC61B) since validation is
forward-only on ~12% of training batch count.

Subject: [PATCH 050/311] refactor: extract _aggregate_validation_losses helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both DynacellUNet and DynacellFlowMatching had identical 7-line
weighted-mean aggregation blocks. Extract into a shared helper to
eliminate duplication and fix sum() on tensors (now torch.stack).
Also unify while→if for dataloader list growth.

Subject: [PATCH 051/311] fix: validate all positions before mutating zarr
 store

When overwrite=False, append_channel was applied to early positions
before a later position raised FileExistsError, leaving the store
in an inconsistent state. Split into a validation pass and a
mutation pass so the store is either fully updated or untouched.

 method rename

Error message in generate_iterative still referenced the old name
generate_sliding_window. Also clarified the generate_sliding_window
docstring to say "tiled sliding window (stride == patch size)" instead
of "non-overlapping tiling" to reduce name/behavior confusion.

Subject: [PATCH 057/311] fix(eval): restore aicssegmentation/itk deps for
 evaluation pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The dynacell → VisCy migration dropped [tool.uv.sources] entries that
pinned aicssegmentation, segmenter-model-zoo, and aicsmlsegment to
numpy-2-compatible forks. PyPI versions crash in sortbyabs() on numpy
2.x. Also declare aicsmlsegment + itk in the eval extra — aicssegmentation
imports itk transitively for anisotropic diffusion smoothing in the
SEC61B vesselness workflow but does not declare it.

Subject: [PATCH 058/311] feat(eval): add limit_positions flag for faster
 iteration

Useful for debugging and smoke-testing against a small subset of the
test set without waiting for the full ~40min run when segmentation
is on the critical path. Defaults to null (process all positions).

mask metrics, subset smoke tests, feature metrics, and force-recompute.
Gives new users a fast path to running the pipeline without reading
every module.

+# dynacell.evaluation
+
+End-to-end evaluation pipeline for virtual staining predictions against fluorescence ground truth.
+
+## Components
+
+| Module | Purpose |
+|---|---|
+| `pipeline.py` | Hydra-driven orchestrator. Loads prediction/GT OME-Zarr plates, computes per-FOV per-timepoint metrics, saves CSVs + NPYs + plots. CLI entrypoint: `dynacell evaluate`. |
+| `metrics.py` | Pixel metrics (PCC, SSIM, NRMSE, PSNR, FSC resolution, spectral PCC, MicroMS3IM), mask metrics (Dice, IoU, precision, recall, accuracy, TP/FP/FN/TN), feature metrics (Frechet distance, polynomial MMD on DINOv3 / DynaCLR / CellProfiler embeddings). |
+| `segmentation.py` | Organelle-specific classical-CV segmentation via `aicssegmentation` workflows (`nucleus`, `membrane`, `nucleoli`, `lysosomes`, `er`, `mitochondria`). Used for mask metrics. |
+| `utils.py` | `DinoV3FeatureExtractor`, `DynaCLRFeatureExtractor`, pairwise feature-similarity helpers, `plot_metrics()` bar/violin plots. |
+| `io.py` | OME-Zarr / tiff readers and writers, prediction preprocessing transforms. |
+| `torch_ssim.py` | GPU-friendly PyTorch SSIM. |
+| `formatting.py` | Metric table formatting helpers. |
+| `spectral_pcc/` | Bandlimited spectral PCC diagnostics and bead simulations. |
+| `_configs/eval.yaml` | Hydra config with `???` MISSING markers for dataset-specific fields. |
+
+## Inputs
+
+Three HCS OME-Zarr plates (position layouts must match 1:1):
+
+- `io.pred_path` — model predictions (channel: `io.pred_channel_name`)
+- `io.gt_path` — fluorescence ground truth (channel: `io.gt_channel_name`)
+- `io.cell_segmentation_path` — precomputed cell segmentation (consumed by feature metrics to crop per-cell patches)
+
+## Running an evaluation
+
+`dynacell evaluate` is a Hydra entrypoint. Override any field on the CLI with `key=value`.
+
+### Minimal example — pixel + mask metrics only
+
+```bash
+uv run dynacell evaluate \
+  target_name=er \
+  io.pred_path=/hpc/projects/virtual_staining/training/dynacell/ipsc/predictions/fnet3d_sec61b.zarr \
+  io.gt_path=/hpc/projects/virtual_staining/training/dynacell/ipsc/dataset_v4/test_cropped/SEC61B.zarr \
+  io.cell_segmentation_path=/hpc/projects/virtual_staining/training/dynacell/ipsc/dataset_v4/test_cropped/SEC61B_segmented_cleaned.zarr \
+  pixel_metrics.spacing=[0.29,0.108,0.108] \
+  save.save_dir=/hpc/projects/virtual_staining/training/dynacell/ipsc/predictions/eval_fnet3d_sec61b
+```
+
+`target_name` ∈ {`nucleus`, `membrane`, `nucleoli`, `lysosomes`, `er`, `mitochondria`} — selects the `aicssegmentation` workflow.
+
+### Smoke test on a subset
+
+```bash
+uv run dynacell evaluate ... limit_positions=10
+```
+
+### Enable feature metrics (DINOv3 + DynaCLR)
+
+Feature metrics require additional config:
+
+```bash
+uv run dynacell evaluate ... \
+  compute_feature_metrics=true \
+  feature_extractor.dinov3.pretrained_model_name=facebook/dinov3-vitl16-pretrain-lvd1689m \
+  feature_extractor.dynaclr.checkpoint=/path/to/dynaclr.ckpt \
+  +feature_extractor.dynaclr.encoder=@configs/recipes/models/dynaclr_encoder.yml
+```
+
+### Force recompute
+
+By default, if `pixel_metrics.npy`, `mask_metrics.npy`, and `feature_metrics.npy` all exist under `save.save_dir`, they are loaded from disk and plots are regenerated. Force a full recompute:
+
+```bash
+uv run dynacell evaluate ... recalculate_metrics=true
+```
+
+## Outputs
+
+Under `save.save_dir`:
+
+```
+pixel_metrics.csv / .npy        # per-FOV per-timepoint pixel metrics
+mask_metrics.csv / .npy         # per-FOV per-timepoint mask metrics
+feature_metrics.csv / .npy      # per-FOV per-timepoint feature metrics (if enabled)
+segmentation_results.zarr       # HCS plate, channels: [prediction_seg, target_seg]
+pixel_metrics/*.png             # bar/violin plots per metric
+mask_metrics/*.png
+feature_metrics/*.png
+```
+
+## Installation
+
+Evaluation pulls heavy optional deps (`aicssegmentation`, `segmenter-model-zoo`, `cubic`, `microssim`, `transformers`, `dynaclr`). Install them with the `eval` extra:
+
+```bash
+uv pip install -e "applications/dynacell[eval]"
+```

Subject: [PATCH 061/311] feat(eval): add GT artifact cache module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduces cache.py with paths, manifest I/O, and read/write helpers
for GT-side organelle masks and feature embeddings. Cache identity is
keyed by (cache_schema_version, gt_path, gt_channel_name,
cell_segmentation_path) so a config mismatch raises StaleCacheError
rather than silently serving the wrong artifacts. Per-artifact params
(spacing, patch_size, model/ckpt hashes) are recorded in the manifest
for granular invalidation.

Self-contained — no pipeline wiring yet. The module is used by later
commits that integrate the cache into evaluate_predictions and add
the precompute-gt CLI.

Subject: [PATCH 062/311] refactor(eval): consolidate save_metrics loop, skip
 empty DataFrames
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The three near-duplicate blocks for mask/pixel/feature metrics are
collapsed into a single loop. Also guard the plot call with
`if not df.empty` — when feature metrics are disabled, the empty
DataFrame was previously crashing plot_metrics on a groupby("FOV")
lookup. Behavior is otherwise identical.

Subject: [PATCH 063/311] refactor(eval): split GT/pred feature computation,
 add force_recompute
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Splits metrics.py feature functions so GT-side work can be cached
separately from prediction-side work. New API:

  cp_target_regionprops, cp_pred_regionprops, cp_pairwise
  deep_target_features, deep_pred_features, deep_pairwise

The old cp_feature_similarity / deep_feature_similarity /
compute_feature_metrics entry points are removed — pipeline.py calls
the split API directly via a thin _compute_feature_metrics_from_split
helper. CP pairing preserves the target-side all-zero column drop and
per-matrix z-score of the original.

Also renames eval.yaml's recalculate_metrics to
force_recompute.final_metrics and introduces the full per-artifact
force_recompute block (gt_masks / gt_cp / gt_dinov3 / gt_dynaclr /
final_metrics / all). io.cell_segmentation_path is now optional
(required only when compute_feature_metrics is true), and
io.gt_cache_dir / io.require_complete_cache are introduced for the
cache work in the next commit.

Bundled changes keep the per-commit test rule: removing the old
metrics API without rewiring pipeline.py would break tests at this
commit.

Subject: [PATCH 064/311] feat(eval): integrate GT cache into
 evaluate_predictions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Per-FOV helpers in new pipeline_cache.py (init_cache_context,
fov_gt_masks, fov_gt_cp_features, fov_gt_deep_features,
flush_manifest) wrap the raw cache I/O in cache.py and honor the
per-artifact force_recompute.* flags plus io.require_complete_cache.

evaluate_predictions now pre-fetches GT masks and per-timepoint GT
feature arrays from the cache before running the timepoint loop. On
a hit it skips the expensive aicssegmentation + feature extraction;
on a miss (and when caching is enabled) it computes and writes to
cache in-place. Manifest is flushed after each position so an
interrupted run preserves completed work.

io.gt_cache_dir remains optional (null = no-op caching, identical to
the previous behavior), so one-off eval runs don't need any cache
plumbing. require_complete_cache=true flips cache misses from fill
to raise — the pattern for parallel sweeps where the cache has
already been primed via precompute-gt.

Also fixes cache.write_mask to overwrite an existing position's
image without tearing down the well group (which iohub's
create_position cannot recreate on its own).

Subject: [PATCH 065/311] feat(eval): add dynacell precompute-gt CLI

Standalone Hydra entrypoint that iterates GT positions and fills the
cache for the artifact families toggled in config.build (masks, cp,
dinov3, dynaclr). Reuses the same pipeline_cache helpers that
evaluate_predictions uses, so a position fills in identically whether
it was built by precompute-gt or filled on-the-fly by evaluate.

precompute.yaml inherits eval.yaml and requires io.gt_cache_dir (the
whole point of the CLI). Designed as a one-time SLURM job ahead of
many parallel evaluate runs with io.require_complete_cache=true.

Routed via __main__._HYDRA_COMMANDS so 'dynacell precompute-gt' is
the user-facing command.

Subject: [PATCH 066/311] docs(eval): document GT cache, precompute-gt CLI,
 parallel sweeps

Extends the evaluation README with the cache layout, a full flag
reference for force_recompute, the parallel-sweep workflow using
require_complete_cache, and a precompute-gt example. Also updates
the components table to cover cache.py, pipeline_cache.py, and
precompute_cli.py, and clarifies which inputs are optional after
the cache changes.

 | Module | Purpose |
 |---|---|
 | `pipeline.py` | Hydra-driven orchestrator. Loads prediction/GT OME-Zarr plates, computes per-FOV per-timepoint metrics, saves CSVs + NPYs + plots. CLI entrypoint: `dynacell evaluate`. |
-| `metrics.py` | Pixel metrics (PCC, SSIM, NRMSE, PSNR, FSC resolution, spectral PCC, MicroMS3IM), mask metrics (Dice, IoU, precision, recall, accuracy, TP/FP/FN/TN), feature metrics (Frechet distance, polynomial MMD on DINOv3 / DynaCLR / CellProfiler embeddings). |
+| `metrics.py` | Pixel metrics (PCC, SSIM, NRMSE, PSNR, FSC resolution, spectral PCC, MicroMS3IM), mask metrics (Dice, IoU, precision, recall, accuracy, TP/FP/FN/TN), feature metrics split into `*_target_*` / `*_pred_*` / `*_pairwise` so GT-side work can be cached separately from predictions. |
 | `segmentation.py` | Organelle-specific classical-CV segmentation via `aicssegmentation` workflows (`nucleus`, `membrane`, `nucleoli`, `lysosomes`, `er`, `mitochondria`). Used for mask metrics. |
+| `cache.py` | GT artifact cache: on-disk layout, manifest I/O, read/write helpers, staleness check. Keyed by `(cache_schema_version, gt_path, gt_channel_name, cell_segmentation_path)`. |
+| `pipeline_cache.py` | Per-FOV load-or-compute wrappers (`fov_gt_masks`, `fov_gt_cp_features`, `fov_gt_deep_features`). Honor `force_recompute.*` flags and the `io.require_complete_cache` contract. |
+| `precompute_cli.py` | Hydra entrypoint for `dynacell precompute-gt`. Iterates GT positions and fills the cache; no eval loop. |
 | `utils.py` | `DinoV3FeatureExtractor`, `DynaCLRFeatureExtractor`, pairwise feature-similarity helpers, `plot_metrics()` bar/violin plots. |
 | `io.py` | OME-Zarr / tiff readers and writers, prediction preprocessing transforms. |
 | `torch_ssim.py` | GPU-friendly PyTorch SSIM. |
 | `formatting.py` | Metric table formatting helpers. |

 ## Inputs
 
-Three HCS OME-Zarr plates (position layouts must match 1:1):
-
-- `io.pred_path` — model predictions (channel: `io.pred_channel_name`)
-- `io.gt_path` — fluorescence ground truth (channel: `io.gt_channel_name`)
-- `io.cell_segmentation_path` — precomputed cell segmentation (consumed by feature metrics to crop per-cell patches)
+- `io.pred_path` — model predictions, HCS OME-Zarr (channel: `io.pred_channel_name`)
+- `io.gt_path` — fluorescence ground truth, HCS OME-Zarr (channel: `io.gt_channel_name`)
+- `io.cell_segmentation_path` — *optional* precomputed cell segmentation, HCS OME-Zarr. Required only when `compute_feature_metrics=true` or when building CP/DINOv3/DynaCLR cache entries. Position layout must match GT/pred 1:1.
+- `io.gt_cache_dir` — *optional* directory for the GT artifact cache. `null` (default) disables caching; set to a writable path to opt in. Required for `dynacell precompute-gt` and for `io.require_complete_cache=true`.

 ### Force recompute
 
-By default, if `pixel_metrics.npy`, `mask_metrics.npy`, and `feature_metrics.npy` all exist under `save.save_dir`, they are loaded from disk and plots are regenerated. Force a full recompute of the saved CSVs:
+The `force_recompute` block has one flag per cacheable artifact plus a shortcut:
+
+| Flag | What it invalidates |
+|---|---|
+| `force_recompute.final_metrics` | Saved CSV/NPY under `save.save_dir` — forces a full re-run of the eval loop. |
+| `force_recompute.gt_masks` | Cached target-side organelle masks for `target_name`. |
+| `force_recompute.gt_cp` | Cached target-side CP regionprops features. |
+| `force_recompute.gt_dinov3` | Cached target-side DINOv3 features for the current model name. |
+| `force_recompute.gt_dynaclr` | Cached target-side DynaCLR features for the current `(ckpt_sha256, encoder_config_sha256)`. |
+| `force_recompute.all` | All of the above. |
+
+Examples:
 
 ```bash
-uv run dynacell evaluate ... force_recompute.final_metrics=true
+# Regenerate only DINOv3 features, keep everything else cached:
+uv run dynacell evaluate ... io.gt_cache_dir=/path/to/cache force_recompute.gt_dinov3=true
+
+# Nuke everything and rebuild:
+uv run dynacell evaluate ... io.gt_cache_dir=/path/to/cache force_recompute.all=true
+```
+
+Without `io.gt_cache_dir`, the cache layer is a no-op (same behavior as before the cache landed), and only `force_recompute.final_metrics` / `.all` have any effect — they control whether the saved CSVs are rebuilt.
+
+## GT artifact cache
+
+Set `io.gt_cache_dir` to write and read back GT-side artifacts so subsequent eval runs skip the expensive per-FOV segmentation and per-cell feature extraction. Typical speedup on SEC61B: ~2× on the second eval run, and scaling with the number of evaluations against the same GT.
+
+### Layout
+
+```
+{gt_cache_dir}/
+  manifest.yaml                          # built_at, params, positions per artifact
+  organelle_masks/{target_name}.zarr     # HCS plate; channel target_seg (bool)
+  features/cp.zarr                       # zarr group, arrays at {row}/{col}/{fov}/t{t}
+  features/dinov3/{model_slug}.zarr      # one plate per model name
+  features/dynaclr/{ckpt_sha12}.zarr     # one plate per (checkpoint, encoder_config)
 ```
 
-Per-artifact flags (`gt_masks`, `gt_cp`, `gt_dinov3`, `gt_dynaclr`) control the GT cache wired up in later commits. `force_recompute.all=true` invalidates everything.
+Cache identity is the tuple `(cache_schema_version, gt_path, gt_channel_name, cell_segmentation_path)`. A mismatch raises `StaleCacheError` — no silent mis-serving when you change GT channel, swap segmentations, or bump the computation-logic version.
+
+### Priming the cache
+
+```bash
+uv run dynacell precompute-gt \
+  target_name=er \
+  io.gt_path=/hpc/.../SEC61B.zarr \
+  io.cell_segmentation_path=/hpc/.../SEC61B_segmented_cleaned.zarr \
+  io.gt_cache_dir=/hpc/.../cache/SEC61B \
+  pixel_metrics.spacing=[0.29,0.108,0.108] \
+  feature_extractor.dinov3.pretrained_model_name=facebook/dinov3-vitl16-pretrain-lvd1689m \
+  feature_extractor.dynaclr.checkpoint=/path/to/dynaclr.ckpt \
+  +feature_extractor.dynaclr.encoder=... \
+  build.masks=true build.cp=true build.dinov3=true build.dynaclr=true
+```
+
+`build.*` toggles control which artifact families get built (all true by default). Skip families you don't need — for example, mask-only:
+
+```bash
+uv run dynacell precompute-gt ... build.masks=true build.cp=false build.dinov3=false build.dynaclr=false
+```
+
+### Parallel sweeps
+
+After a full precompute, launch many `dynacell evaluate` jobs in parallel against the same cache with `io.require_complete_cache=true`. Missing entries now raise `StaleCacheError` instead of triggering concurrent writes (zarr `mode="a"` is not safe under concurrent write).
+
+```bash
+uv run dynacell evaluate ... io.gt_cache_dir=/hpc/.../cache/SEC61B io.require_complete_cache=true
+```
+
+### Cache invalidation
+
+We deliberately do **not** fingerprint the GT or cell_segmentation zarr *contents*. If you modify them in place, either bump `cache_schema_version` in `cache.py`, set the appropriate `force_recompute.*` flag, or delete `{gt_cache_dir}/`.

Subject: [PATCH 067/311] refactor(eval): batch zarr opens per FOV, dedup slug,
 type kind
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

/simplify pass over the cache work. Three cleanups:

1. Open each feature zarr group once per FOV (not once per timepoint)
   via a new open_features_group context manager + two helpers
   (read_features_from_group, write_features_to_group). Shrinks the
   per-run zarr.open_group count from ~2T×N_artifacts×N_positions
   (~2600 on SEC61B) to N_artifacts×N_positions (~300). read_features
   / write_features stay as the single-shot convenience API.

2. Extract _load_or_compute_feature_timepoints shared loop so
   fov_gt_cp_features and fov_gt_deep_features stop copy-pasting the
   miss-detection + compute + cache-write logic.

3. Add FeatureKind = Literal["cp", "dinov3", "dynaclr"] and use it
   everywhere `kind` is accepted, so the three valid values are
   visible at type-check time. Also consolidate the duplicated slug
   helper into cache.feature_slug (was _safe_slug in cache.py and
   _slug in pipeline_cache.py).

Also drops one redundant narration comment in pipeline.py.

All 142 non-training tests still pass.

Subject: [PATCH 068/311] refactor(eval): encapsulate cache dirty flag, narrow
 broad except
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addresses two PR #404 review findings:

1. `_CacheContext._manifest_dirty` was mutated directly from helper
   call sites, leaking implementation detail. Adds `mark_manifest_dirty`
   and `consume_manifest_dirty` methods and routes every external touch
   through them. Only the dataclass itself now references the private
   field.

2. `resolve_dynaclr_encoder_cfg` used `except Exception` to detect a
   missing nested config key — wider than needed and against CLAUDE.md
   guidance. Replaced with `OmegaConf.select(..., default=None)`, which
   handles missing keys natively without a try/except.

Subject: [PATCH 069/311] test(eval): add pinned-value regression tests for
 feature pairing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addresses a PR #404 review finding: the split GT/pred feature API had
structural tests (empty inputs, column-drop, shape mismatch) but no
pinned-value regression guard. Adds two tests that seed deterministic
synthetic inputs and assert exact output values for CP_FID / CP_KID /
CP_Median_Cosine_Similarity and the DINOv3 equivalents.

If anyone later changes the column-drop, per-side z-score, or
FID/KID/cosine pairing logic — or a dependency shifts numerics — these
tests will fail rather than silently drifting metrics.

ckpt's. Falls back to recompute on any OSError (read-only dir, NFS
flake) and on corrupt non-hex sidecars.

Subject: [PATCH 073/311] feat(cli): strip launcher and benchmark reserved keys
 in compose

dynacell's benchmark leaf YAMLs carry two reserved top-level keys:
`launcher:` (sbatch/runtime metadata) and `benchmark:` (experiment
identifiers). LightningCLI rejects unknown top-level keys, so these must
be removed before the composed config reaches the CLI. Widen
_maybe_compose_config to:

- strip both reserved keys whether or not `base:` is present
- extract _find_config_arg and _replace_config_path_in_argv helpers

This unblocks `uv run dynacell fit -c <benchmark-leaf.yml>` without
requiring the dedicated benchmark submit tool.

 virtual_staining skeleton
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Lands the benchmark config layout without any runnable leaves yet:

- BENCHMARK_CONFIG_SCHEMA.md — reference doc (previously untracked)
- virtual_staining/README.md — reserved-keys contract, compose+submit
  docs
- shared/train_sets/ipsc_confocal.yml — imaging modality defaults
- shared/targets/{er_sec61b, mito_tomm20, nucleus, membrane}.yml — four
  targets with channel names, train-side data paths, normalizations,
  and RandWeightedCropd
- shared/model_overlays/celldiff_{fit,predict}.yml — model + trainer
  recipe binding + mode-specific data hparams and GPU aug stack
- shared/launcher_profiles/{mode_fit, mode_predict, hardware_h200_single,
  runtime_single_gpu}.yml — launcher metadata split across axes
- shared/predict_sets/ipsc_confocal.yml — predict-set metadata +
  source_channel (duplicated from train_sets because predict leaves
  don't compose train_sets)

Train/predict leaves land in the next two commits.

+# Benchmark Config Schema For Active VisCy Training
+
+This document captures the proposed active benchmark config layout for
+`VisCy/applications/dynacell`, using one-file benchmark configs with embedded
+launcher metadata.
+
+The goal is to support:
+
+- small public example configs
+- real benchmark training configs
+- no drift between training config and SLURM resource settings
+- scalable organization across model families, train sets, targets, and
+  prediction domains
+
+This document covers the active benchmark-training surface for two experiment
+phases:
+
+- Phase 1
+  - target: `er`
+  - train sets:
+    - `ipsc_confocal`
+    - `ipsc_confocal_plus_mantis`
+  - model families:
+    - `fnet3d`
+    - `unext2_scratch`
+    - `unext2_fcmae`
+    - `unetvit3d`
+    - `celldiff`
+- Phase 2
+  - targets:
+    - `mito`
+    - `nucleus`
+    - `membrane`
+  - train sets:
+    - `ipsc_confocal`
+    - `ipsc_confocal_plus_mantis`
+  - model families:
+    - `selected_deterministic`
+    - `celldiff`
+
+Prediction, evaluation, and paper orchestration are downstream stages. They are

+
+## Key Rule
+
+- `configs/examples/` stays generic and public
+- `configs/benchmarks/virtual_staining/...` becomes the real benchmark layer
+- archived SEC61B configs in `dynacell-paper` remain historical reference only
+
+## Experiment Phase Mapping
+
+The directory layout is meant to scale without changing shape between phases.
+Only the populated leaves change.
+
+### Phase 1
+
+Phase 1 fills the `train/er/...` subtree for all model families and both train
+sets:
+
+- `train/er/ipsc_confocal/fnet3d.yml`
+- `train/er/ipsc_confocal/unext2_scratch.yml`
+- `train/er/ipsc_confocal/unext2_fcmae.yml`
+- `train/er/ipsc_confocal/unetvit3d.yml`
+- `train/er/ipsc_confocal/celldiff.yml`
+- the same five files under `train/er/ipsc_confocal_plus_mantis/`
+
+This is the broad comparison phase used to narrow model choice.
+
+### Phase 2
+
+Phase 2 reuses the same schema and shared-axis files, but fills only the
+`mito`, `nucleus`, and `membrane` subtrees, and only for the two shortlisted
+model families:
+
+- `selected_deterministic`
+- `celldiff`
+
+That produces these leaf patterns:
+
+- `train/mito/ipsc_confocal/selected_deterministic.yml`
+- `train/mito/ipsc_confocal/celldiff.yml`
+- `train/mito/ipsc_confocal_plus_mantis/selected_deterministic.yml`
+- `train/mito/ipsc_confocal_plus_mantis/celldiff.yml`
+- the same four-file pattern for `nucleus/`
+- the same four-file pattern for `membrane/`
+
+This is intentionally repetitive. That repetition is a feature of the tree, not
+a design bug: it keeps every runnable benchmark job addressable by target,
+train set, and model family without introducing a second naming system.
+
+### Scalability Constraint
+
+The shared-axis directories are what keep the repeated leaf structure from
+turning into a maintenance problem:
+
+- `shared/train_sets/` owns data-source membership and base data paths
+- `shared/targets/` owns organelle-specific target-channel choices
+- `shared/model_overlays/` owns model-family defaults
+- `shared/launcher_profiles/` owns reusable hardware / mode / runtime policy
+- `shared/predict_sets/` owns prediction-domain inputs
+
+New organelles or train sets should usually add one shared-axis file plus a new
+leaf subtree, not a new config convention.
+
+## Launcher Profile Schema
+
+Launcher metadata should be composable too, not stored in one flat profile
+registry.
+
+The reusable axes are:
+
+- mode
+  - `fit`
+  - `predict`
+- hardware class
+  - `a6000_single`
+  - `h100x4`
+  - `h200_single`
+- runtime behavior
+  - `ddp`
+  - `single_gpu`
+  - `resume`
+
+Use separate launcher-profile files under:
+
+`applications/dynacell/configs/benchmarks/virtual_staining/shared/launcher_profiles/`
+
+### Mode Profile
+
+`mode_fit.yml`
+
+```yaml
+launcher:
+  mode: fit
+```
+
+### Hardware Profile
+
+`hardware_h100x4.yml`
+
+```yaml
+launcher:
+  sbatch:
+    partition: gpu
+    nodes: 1
+    ntasks_per_node: 4
+    gpus: 4
+    cpus_per_task: 12
+    mem_per_cpu: "20G"
+    time: "48:00:00"
+    constraint: "a100_80|h100|h200"
+```
+
+### Runtime Profile
+
+`runtime_ddp.yml`
+
+```yaml
+launcher:
+  runtime:
+    use_srun: true
+    cleanup_tmp: true
+  env:
+    PYTHONUNBUFFERED: "1"
+    PYTHONFAULTHANDLER: "1"
+    NCCL_DEBUG: "INFO"
+```
+
+### Example Single-GPU Profile
+
+`hardware_h200_single.yml`
+
+```yaml
+launcher:
+  sbatch:
+    partition: gpu
+    nodes: 1
+    ntasks_per_node: 1
+    gpus: 1
+    cpus_per_task: 8
+    mem: "256G"
+    time: "48:00:00"
+    constraint: "h200|h100|a100_80"
+```
+
+### Example Predict Profile
+
+`mode_predict.yml`
+
+```yaml
+launcher:
+  mode: predict
+```

+
+## Submit Tool Contract
+
+File:
+
+`applications/dynacell/tools/submit_benchmark_job.py`
+
+Behavior:
+
+1. Accept one config path.
+2. Compose it using the same base-resolution logic VisCy already uses.
+3. Read the resolved `launcher:` block after composition.
+4. Strip `launcher:` from the resolved config.
+5. Write:
+   - resolved runtime config to:
+     - `<run_root>/resolved/<mode>.resolved.yml`
+   - rendered SLURM script to:
+     - `<run_root>/slurm/<timestamp>_<job_name>.sbatch`
+6. Submit with `sbatch`, unless `--dry-run`.
+
+Command shape:
+
+```bash
+uv run python applications/dynacell/tools/submit_benchmark_job.py \
+  applications/dynacell/configs/benchmarks/virtual_staining/train/er/ipsc_confocal/celldiff.yml
+```
+
+Optional flags:
+
+```bash
+--dry-run
+--print-script
+--print-resolved-config
+--override trainer.max_epochs=10
+```
+
+## Important Rule
+
+`launcher:` is for the submit tool, not for direct `dynacell fit`.
+
+So:
+
+- direct `dynacell fit -c <leaf.yml>` is not the primary entrypoint
+- primary entrypoint is:
+  - `submit_benchmark_job.py <leaf.yml>`
+- the submit tool produces the stripped resolved config and then runs
+  `dynacell fit -c <resolved.yml>`
+
+This avoids any risk that Lightning/Hydra rejects unknown top-level keys.

+After Phase 1 results select the deterministic shortlist winner, add the Phase
+2 leaves by reusing the same shared files and changing only:
+
+- target subtree: `mito/`, `nucleus/`, `membrane/`
+- model leaf names: `selected_deterministic.yml`, `celldiff.yml`
+- phase metadata in `benchmark.phase`
+
+The required file patterns are:
+
+```text
+applications/dynacell/configs/benchmarks/virtual_staining/train/mito/ipsc_confocal/selected_deterministic.yml
+applications/dynacell/configs/benchmarks/virtual_staining/train/mito/ipsc_confocal/celldiff.yml

+applications/dynacell/configs/benchmarks/virtual_staining/train/membrane/ipsc_confocal_plus_mantis/celldiff.yml
+```
+
+Only one extra naming decision is needed at that point: replace
+`selected_deterministic.yml` with the actual winning model family
+(`fnet3d.yml`, `unext2_scratch.yml`, `unext2_fcmae.yml`, or `unetvit3d.yml`).

+# Virtual Staining Benchmark Configs
+
+Composable leaf-per-experiment configs for dynacell virtual-staining benchmarks.
+
+## Reserved top-level keys
+
+Two top-level YAML keys are **reserved for dynacell** and are stripped
+from the composed config before it reaches LightningCLI:
+
+- `launcher:` — sbatch directives, runtime env, job metadata. Consumed by
+  `applications/dynacell/tools/submit_benchmark_job.py`.
+- `benchmark:` — informational experiment metadata (target, train_set,
+  experiment_id). Readable by downstream reporting; not consumed by
+  Lightning.
+
+The strip happens inside `viscy_utils.cli._maybe_compose_config`. This
+means `uv run dynacell fit -c <leaf.yml>` works for any benchmark leaf
+without the dedicated submit tool.
+
+## Layout
+
+```
+virtual_staining/
+  shared/
+    train_sets/<name>.yml         # imaging modality + source_channel defaults
+    targets/<target>.yml          # target_channel, train data_path, norms, CPU augs
+    model_overlays/
+      celldiff_fit.yml            # model + fit trainer + train data hparams
+      celldiff_predict.yml        # model + predict trainer + predict data hparams
+    launcher_profiles/
+      mode_<fit|predict>.yml      # launcher.mode
+      hardware_<hw>.yml           # sbatch directives + trainer.devices
+      runtime_<rt>.yml            # launcher.runtime + launcher.env
+    predict_sets/<name>.yml       # predict_set metadata + source_channel
+  train/<org>/<train_set>/<model>.yml
+  predict/<org>/<train_set>/<model>/<predict_set>.yml
+```
+
+## Composition order
+
+Last wins via deep-merge. Lists replace wholesale — layers that own list
+fields (`callbacks`, `augmentations`, etc.) own the **full** list.
+
+**Train leaf** (at `train/<org>/<train_set>/<model>.yml`):
+
+```yaml
+base:
+  - ../../../shared/train_sets/<train_set>.yml
+  - ../../../shared/targets/<target>.yml
+  - ../../../shared/model_overlays/<model>_fit.yml
+  - ../../../shared/launcher_profiles/mode_fit.yml
+  - ../../../shared/launcher_profiles/hardware_<hw>.yml
+  - ../../../shared/launcher_profiles/runtime_<rt>.yml
+```
+
+**Predict leaf** (at `predict/<org>/<train_set>/<model>/<predict_set>.yml`):
+
+```yaml
+base:
+  - ../../../../shared/predict_sets/<predict_set>.yml
+  - ../../../../shared/targets/<target>.yml
+  - ../../../../shared/model_overlays/<model>_predict.yml
+  - ../../../../shared/launcher_profiles/mode_predict.yml
+  - ../../../../shared/launcher_profiles/hardware_<hw>.yml
+  - ../../../../shared/launcher_profiles/runtime_<rt>.yml
+```
+
+## Running
+
+- `uv run dynacell fit -c configs/benchmarks/virtual_staining/train/<org>/<train_set>/<model>.yml`
+- `uv run dynacell predict -c configs/benchmarks/virtual_staining/predict/<org>/<train_set>/<model>/<predict_set>.yml`
+- `uv run python applications/dynacell/tools/submit_benchmark_job.py <leaf.yml>` — submits via sbatch.
+
+## Source channel contract
+
+`data.init_args.source_channel` lives in `train_sets/` and `predict_sets/`
+(duplicated — must be kept in sync) because it's a property of the
+imaging modality, not the target. Predict leaves don't compose train_sets,
+so the predict_set file has to own its own `source_channel`.

Subject: [PATCH 075/311] feat(configs): add CellDiff train leaves for
 er/mito/nucleus/membrane
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Four benchmark leaves at configs/benchmarks/virtual_staining/train/<org>/
ipsc_confocal/celldiff.yml — one per organelle. Each composes the shared
axes (train_set, target, celldiff_fit overlay, launcher profiles) and
carries organelle-specific WandB run name, checkpoint dirpath, and
launcher.{job_name, run_root} in the leaf body.

test_benchmark_config_composition.py composes both the pre-schema
fit_celldiff.yml and the new leaf through load_composed_config, strips
reserved keys, and asserts the full intersection of model/data/trainer
fields matches. All four organelles pass.

Subject: [PATCH 076/311] feat(configs): add CellDiff predict leaves
 (self-predict)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Four predict leaves at configs/benchmarks/virtual_staining/predict/<org>/
ipsc_confocal/celldiff/ipsc_confocal.yml. Each overrides:

- data.init_args.data_path to the test_cropped store for the organelle
- data.init_args.normalizations to Phase3D-only (predict doesn't use
  target normalization — target isn't loaded)
- data.init_args.augmentations to [] (clears target-inherited
  RandWeightedCropd; predict has no CPU augs)
- trainer.callbacks to a single HCSPredictionWriter with the organelle's
  output zarr

Extends test_benchmark_config_composition.py with a predict-side
equivalence test that asserts model.init_args.{num_generate_steps,
predict_method, predict_overlap, ckpt_path, net_config}, the predict
data.init_args key intersection, HCSPredictionWriter output_store
equality, and a 'test_cropped/' guard on data_path. All four predict
leaves pass.

Subject: [PATCH 077/311] feat(tools): add submit_benchmark_job.py with dry-run
 and sbatch template

Drives one benchmark leaf end-to-end: compose via load_composed_config,
apply --override (stdlib dotlist, interpolation forbidden), validate
launcher block, consistency-check trainer.devices vs sbatch.gpus, render
sbatch from tools/sbatch_template.sbatch using a string.Template
subclass with @@ delimiter (so shell $VARs pass through verbatim), and
submit.

The SBATCH directive render order (job-name, time, nodes, ntasks,
partition, cpus-per-task, gpus, mem, constraint, output, error) is
pinned explicitly to match Dihan's run_celldiff.slurm. Byte-equivalence
test against the SEC61B train leaf confirms the rendered sbatch
differs only on the final srun --config path.

Flags: --dry-run, --print-script, --print-resolved-config,
--override key.path=value (repeatable).

Subject: [PATCH 078/311] chore(configs): archive Dihan's CellDiff trees under
 tools/LEGACY
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

git-renamed the four pre-schema CellDiff trees (memb/nucl/sec61b/tomm20,
fit+predict YAMLs and run_celldiff.slurm) from
applications/dynacell/examples/configs/ to
applications/dynacell/tools/LEGACY/examples_configs/. Empty examples/
parent removed.

Post-move, the eight YAMLs' base: paths needed one additional '..' to
still resolve to configs/recipes/ — the only content change. This keeps
the equivalence test in test_benchmark_config_composition.py able to
compose the LEGACY files as the source-of-truth reference. Both test
files' EXAMPLES paths updated to the new location.

tools/LEGACY/README.md documents the contract: reference-only, not for
direct launch; delete after one successful end-to-end submit run and
2026-06-30 at the earliest.

+# LEGACY — Dihan's pre-schema CellDiff configs
+
+**Reference-only.** `base:` paths were patched post-move from
+`../../../configs/recipes/...` to `../../../../configs/recipes/...` so the
+equivalence test in `tests/test_benchmark_config_composition.py` can still
+compose them. The patched files are not intended to be launched directly —
+use the migrated leaves under `configs/benchmarks/virtual_staining/` via
+`submit_benchmark_job.py`.
+
+## Why kept
+
+These are the source-of-truth hyperparameter reference for the migrated
+benchmark leaves under `configs/benchmarks/virtual_staining/train/` and
+`.../predict/`. The equivalence test
+(`tests/test_benchmark_config_composition.py`) asserts that each migrated
+leaf composes to the same values these files compose to. Delete this tree
+only after:
+
+1. One successful end-to-end `submit_benchmark_job.py` run against a
+   migrated leaf (fit or predict), verified on wandb/disk; and
+2. 2026-06-30 at the earliest.
+
+Whoever deletes this should note both conditions in the commit message.
+
+## Rerunning these configs
+
+Copy them back out to the original location or fix the `base:` paths
+manually. They are preserved exactly as they were when they worked.

Subject: [PATCH 079/311] docs(dynacell): update README with benchmark layout
 and submit tool

Adds the configs/benchmarks/virtual_staining/ layer to the config
structure section, points at its own README for composition order, and
documents the submit_benchmark_job.py tool with --dry-run examples.
Also notes that launcher:/benchmark: reserved keys are stripped
automatically by _maybe_compose_config.

+- `tools/submit_benchmark_job.py` — drives one benchmark leaf end-to-end
+  (compose → strip launcher metadata → render sbatch → submit). Use
+  `--dry-run` to inspect without submitting.
+- `tools/LEGACY/` — archived pre-schema CellDiff configs kept as the
+  equivalence reference. Not for direct launch; see its README.
+
+### Benchmark submit
 
-Benchmark-specific configs (SEC61B, nuclei-mix) live in the `dynacell-paper` repo.
+```bash
+# Dry-run a CellDiff fit for ER (SEC61B) on ipsc_confocal, print the rendered sbatch:
+uv run python applications/dynacell/tools/submit_benchmark_job.py \
+    applications/dynacell/configs/benchmarks/virtual_staining/train/er/ipsc_confocal/celldiff.yml \
+    --dry-run --print-script
+
+# Submit for real (drops --dry-run):
+uv run python applications/dynacell/tools/submit_benchmark_job.py \
+    applications/dynacell/configs/benchmarks/virtual_staining/train/er/ipsc_confocal/celldiff.yml
+```
+
+Benchmark leaves carry two reserved top-level YAML keys (`launcher:` and
+`benchmark:`) that are stripped automatically before the config reaches
+LightningCLI, so `uv run dynacell fit -c <benchmark-leaf.yml>` also works
+without the submit tool.

Subject: [PATCH 080/311] refactor(utils): promote deep_merge to public API

viscy_utils.compose._deep_merge was private, forcing dynacell's
submit_benchmark_job.py to keep a byte-identical copy with a docstring
explaining the duplication. Drop the underscore and export it. Prevents
silent drift between the two copies if one is updated (e.g. changing
list-replace to list-append semantics).

Subject: [PATCH 081/311] fix(tools): address simplify review findings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three substantive fixes plus cleanup:

- Drop the @@overrides tail from sbatch_template.sbatch. Previously
  --override tokens were both merged into the resolved YAML AND appended
  to the srun command line, applying the overrides twice. For scalar
  overrides this happened to be idempotent; for list overrides it would
  have silently duplicated entries.
- Make --print-script and --print-resolved-config imply skip-submission.
  Previously running submit_benchmark_job.py with --print-resolved-config
  alone (no --dry-run) would still sbatch the job — a surprising
  foot-gun.
- Use the newly-public deep_merge from viscy_utils.compose; drop the
  duplicated copy from submit_benchmark_job.py.
- Change _apply_override to return the merged dict instead of mutating
  in place via clear()+update(). Simpler contract matching _deep_merge.
- Deduplicate the stat() call in ckpt_sha256_12 (Path.exists() followed
  by Path.stat() was two syscalls for one result).
- Strip stale "# Equivalent to examples/configs/..." comments from the 8
  leaf YAMLs — the referenced path was moved to tools/LEGACY/ in an
  earlier commit.
- Clean up author-referencing narration comments ("matches Dihan's
  ...") — the code is the contract now.

Three confirmed review findings:

- Remove sys.path.insert from test_submit_benchmark_job.py (CLAUDE.md
  bans sys.path mutation). Replace with pytest pythonpath config in the
  workspace pyproject.toml pointing at applications/dynacell/tools so
  the test can import submit_benchmark_job.
- Make --dry-run the mode that writes the resolved YAML and sbatch to
  disk (previously nothing wrote files outside the real-submit path,
  which meant --dry-run rendered a path it never populated). --print-*
  flags are now documented as preview-only: stdout inspection, no disk
  writes, no submission.
- Drop redundant FileNotFoundError from the except tuple in
  ckpt_sha256_12 — it's an OSError subclass.

Subject: [PATCH 083/311] fix(tools): decouple preview contract from --dry-run
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prior semantics had --dry-run write resolved YAML + sbatch to
launcher.run_root, which fails with PermissionError on production
run_roots the caller can't write to — making --dry-run unsafe as a
preview mechanism despite its name.

New contract:
- --print-script / --print-resolved-config: pure preview, stdout only,
  no disk writes, no submission. Safe on any leaf regardless of
  run_root write permission.
- --dry-run alone: write resolved YAML + sbatch to run_root without
  submitting. Requires write permission.
- --dry-run combined with --print-*: --print-* wins (still a pure
  preview).
- Bare invocation: write + submit (unchanged).

README updated to use --print-script for the safe-preview example and
to document --dry-run's write-to-run_root semantics.

Subject: [PATCH 084/311] fix(tools): shlex-quote env values in rendered sbatch

_render_env_block previously wrote `export KEY=VALUE` verbatim. If a
value contains a space or shell metacharacter, the export breaks or
opens an injection path via --override launcher.env.FOO=... Quote
values with shlex.quote() and validate keys match a shell identifier
regex. No-op for the current YAML values (INFO, 1, etc. quote to
themselves), preserving byte-equivalence with Dihan's reference
run_celldiff.slurm.

Subject: [PATCH 086/311] docs(dynacell): document submit tool flags and
 preview contract

The previous docs only showed --print-script/--dry-run/submit, which
hid --print-resolved-config and --override entirely and left the
preview-vs-write-vs-submit semantics implicit. After the 7706ae8
preview-contract fix, the distinction between "safe preview" and
"writes to run_root" is user-visible, so it needs to be spelled out.

 LightningCLI, so `uv run dynacell fit -c <benchmark-leaf.yml>` also works
 without the submit tool.

Subject: [PATCH 087/311] docs(eval): note ckpt sha256 sidecar under cache
 identity

Commit 1690b7f added a <ckpt>.sha256 sidecar to skip re-hashing large
DynaCLR checkpoints on every eval run, but the README only showed
ckpt_sha12 as a cache key. Surface the sidecar + mtime-guard so users
know that touching/replacing the ckpt invalidates it automatically
and don't have to grep cache.py to understand the behavior.

Subject: [PATCH 088/311] feat(configs): migrate UNetViT3D and FNet3D paper
 SEC61B leaves to schema

Provides runnable substitutes for two pre-schema SEC61B fit configs so
teammates can point at a single leaf and reproduce the same training
protocol via submit_benchmark_job.py:

- UNetViT3D: new leaf matches Dihan's fit_unetvit3d.yml field-for-field
  (minus a copy-paste net_config: override that jsonargparse rejected,
  making the legacy config unloadable anyway).
- FNet3D paper baseline: new leaf matches the LightningCLI config.yaml
  Lightning saved when the reference run trained, and the wandb-logged
  model hyperparameters across all 9 runs in the FNet3D_iPSC_SEC61B_paper
  group. The earlier fit_fnet3d_paper.yml was git-removed in 42d66d7, so
  the on-disk config.yaml is the source of truth.

Divergence between fnet_paper and the shared target norms/augs (mean/std
vs median/iqr; 8 small crops vs 2 large transformer crops) is handled by
list-replacing in the model overlay rather than branching the target
axis.

+The `fnet3d_paper` leaf has no source file in LEGACY — the earlier
+`fit_fnet3d_paper.yml` was git-removed in commit `42d66d7`. The new leaf
+is verified directly against the LightningCLI config.yaml that Lightning
+saved when the run trained, at
+`/hpc/projects/comp.micro/virtual_staining/models/dynacell/ipsc/sec61b/fnet3d_paper/config.yaml`.
+The equivalent wandb-logged model hyperparameters
+(in project `computational_imaging/dynacell`, run group
+`FNet3D_iPSC_SEC61B_paper`) match across all 9 runs in the group.
+
+### Notes on `fit_unetvit3d.yml`
+
+The legacy file carries a latent copy-paste bug: `net_config:` nested
+under `DynacellUNet`'s `init_args`. `DynacellUNet.__init__` takes
+`model_config:`, not `net_config:`, so jsonargparse rejects that
+override — the legacy config would fail to load if run today. The
+override is also redundant with the recipe's `model_config.input_spatial_size`,
+so the new leaf drops it. Runtime-equivalent in every other field.

Subject: [PATCH 089/311] refactor(data): rename HCSDataModule preload kwarg to
 mmap_preload
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

"preload" suggested RAM residency; the flag has always been mmap-to-
scratch since commit 7de5e0b replaced the old RAM-based in_memory with
MemoryMappedTensor. Rename makes the mechanism readable from the kwarg
alone and stops the drift where users (including me) reasoned about it
as "load into RAM."

Rename applies at the kwarg + attribute level on HCSDataModule, plus
all YAML configs that set it and the tests that pass it.

Not renamed: preloaded_fovs / _preloaded / _preloaded_masks in
sliding_window.py and foreground_masks.py — those are generic
"pre-supplied tensor list" parameters whose source isn't necessarily
mmap.

Subject: [PATCH 090/311] feat(configs): add FNet3D paper-baseline fit leaves
 for 3 more organelles

Extends the fnet3d_paper recipe from SEC61B (er) to mito/TOMM20,
nucleus, and membrane so the paper-baseline training protocol (FNet3D
depth=4, lr=1e-3 Constant, fp32, 8 small weighted crops, YX flips,
50k steps, seed=0) can be fit for every target in the benchmark
matrix.

Mito inherits the overlay's Structure-keyed norms/augs unchanged
(TOMM20 uses Structure as target_channel). Nucleus and membrane
list-replace normalizations/augmentations/val_augmentations in the
leaf body to re-key them on Nuclei/Membrane, which are their
respective target_channels.

Subject: [PATCH 091/311] feat(tools): make sbatch constraint directive
 optional
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hardware profiles that want to run on any available GPU need a way to
say "no --constraint line" without the renderer crashing on a missing
key. Let profiles express this by setting constraint: null (or omitting
it entirely) and skip the line at render time. Other directives stay
required — only constraint is gated.

Enables the FNet3D paper-baseline profile to match its pre-schema slurm
(which had no --constraint) instead of inheriting the H200-pinned
profile from CellDiff/UNetViT.

--constraint (it trained on RTX A6000) and a 20-day wall-time. The
overlay also kept max_steps=50000 (the original launch value); the
paper training converged to max_steps=200000 via CLI-bump continuations.

Submitting these leaves as-written produced jobs pinned to H200 that
would time out at day 4 with only a quarter of the paper training
done. Add a new hardware_gpu_any_long profile that matches the paper
slurm (no constraint, 20-day time) and bump max_steps to 200000 so a
fresh submission reaches the same final checkpoint count without
needing continuation restarts.

Subject: [PATCH 093/311] fix(configs): bump gpu_any_long mem to 512G to
 survive mmap preload

The nucleus fnet3d_paper run OOM-killed at MaxVMSize=264G under the
256G profile cap. HCSDataModule mmap_preload stages the training zarr
to /dev/shm, which is tmpfs-backed on CZB nodes, so the staged bytes
are counted against host memory alongside the training process. 512G
gives headroom for the mmap buffer plus dataloader workers.

Subject: [PATCH 095/311] fix(configs): narrow 512G mem bump to
 cell.zarr-backed leaves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reverting the shared gpu_any_long profile to 256G — ER (SEC61B) and
MITO (TOMM20) paper runs both fit there; only cell.zarr-backed
nucleus/membrane push MaxVMSize past the cap after mmap_preload
stages the plate to /dev/shm. Moving the 512G cap into each of those
two leaves as a launcher.sbatch.mem override keeps the shared profile
honest and avoids reserving 2x mem for jobs that don't need it.

Subject: [PATCH 096/311] fix(configs): drop num_log_steps from unetvit3d
 overlay

Slurm 31104787 crashed at parse time with
  Option 'num_log_steps' is not accepted
when launched against train/er/ipsc_confocal/unetvit3d.yml. The flag
belongs to DynacellFlowMatching (CellDiff), not DynacellUNet. It got
copy-pasted from celldiff_fit.yml when the UNetViT3D overlay was
written and slipped past the YAML-dict equivalence test (which did
not actually instantiate LightningCLI).

The legacy fit_unetvit3d.yml had the same leftover, alongside the
previously-known net_config copy-paste. Both are now documented in
LEGACY/README.md and stripped from the legacy side in the equivalence
test before comparing.

+The legacy file carries two copy-paste bugs from celldiff that jsonargparse
+rejects at parse time:
+
+1. `net_config:` nested under `DynacellUNet`'s `init_args`.
+   `DynacellUNet.__init__` takes `model_config:`, not `net_config:`, so
+   jsonargparse rejects that override. Also redundant with the recipe's
+   `model_config.input_spatial_size`.
+2. `num_log_steps: 10` under `DynacellUNet`'s `init_args`. That kwarg
+   belongs to `DynacellFlowMatching` (CellDiff), not `DynacellUNet`, so
+   jsonargparse rejects it with `Option 'num_log_steps' is not accepted`.
+   Confirmed by an actual fit crash on slurm job 31104787 when the new
+   overlay still carried this field over from celldiff_fit.yml.
+
+The new leaf drops both. Runtime-equivalent in every other field.

Subject: [PATCH 097/311] test(configs): allow checkpoint policy divergence in
 unetvit3d test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Dihan's commit ffd84d7 upgraded the new UNetViT3D leaf's ModelCheckpoint
policy (monitor=loss/validate, save_top_k=4) to match the fnet3d_paper
pattern, while the legacy fit_unetvit3d.yml it reproduces kept the old
save_top_k=-1 / no-monitor policy. The strict callbacks equality
assertion treated this intentional tightening as a regression.

Loosen the assertion to check structural equivalence (same callback
classes, same dirpath, same save_last) — i.e. downstream predict leaves
still resolve the same last.ckpt path. Policy knobs like save_top_k
and monitor can evolve without breaking the reproduction contract.

Subject: [PATCH 098/311] feat(configs): add UNeXt2 SEC61B fit leaf (Run 4
 reproduction)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reproduces wandb run 20260409-020023_UNeXt2_iPSC_SEC61B from Dihan's
legacy commit 46e4c79 through the new benchmark schema:

- shared/model_overlays/unext2_fit.yml  — convnextv2_tiny backbone +
  MixedLoss(L1+DSSIM) + z=20/bs=32/lr=4e-4 retuned hparams.
- shared/launcher_profiles/hardware_4gpu.yml  — 4-GPU DDP profile,
  constraint-free, 512G mem / 4d time.
- train/er/ipsc_confocal/unext2.yml  — the leaf, with Lightning
  logger + ModelCheckpoint(save_top_k=5) matching the paper run.
- tools/LEGACY/examples_configs/sec61b/fit_unext2.yml  — archived
  Run 4 config git-extracted from 46e4c79 for equivalence test.
- tests/test_benchmark_config_composition.py  — new
  test_unext2_train_leaf_matches_legacy asserts composed leaf ==
  archived legacy on model, data, trainer, callbacks, logger.

Earlier Run 1-3 runs (20260403, 20260406) used lr=0.0002, bs=8, z=15
-- this leaf covers the converged Run 4 only. Earlier exploratory
arm would need a separate leaf if wanted.

Subject: [PATCH 100/311] feat(dynacell): add denoise_sliding_window with
 overlap averaging

Adds CELLDiff3DVS.denoise_sliding_window, which estimates the
conditional mean by tiling the input into overlapping patches,
applying a single-step Euler update (t=0, x1 = xt + v) per patch,
and averaging overlapping regions via sum/count accumulation.

Wires up "denoise" as a valid predict_method in DynacellFlowMatching,
forwarding predict_overlap to overlap_size.

Subject: [PATCH 102/311] perf(data): preserve native dtype in mmap_preload,
 cast on sample read
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The prepare_data() preload path used a hardcoded torch.float32 buffer
and called .astype(np.float32) on every zarr read. On a uint16/int16
microscopy dataset this doubles the mmap buffer size; on any source
dtype it's an unnecessary GIL-held numpy copy on the hot path, and
with a ThreadPoolExecutor of 16 workers the GIL-bound copy collapses
effective parallelism to ~1 core. The net observed throughput on
SEC61B (~86 GB target buffer) was ~28 MB/s.

Three changes:
  * Allocate the data and fg_mask MemoryMappedTensor buffers with the
    zarr array's native dtype (new _torch_dtype_from_numpy helper does
    the conversion via torch.from_numpy(np.empty()).dtype).
  * Drop .astype(np.float32) from _write_fov / _write_mask; writes go
    directly into the matching-dtype buffer.
  * Cast to float32 at patch-sampling time in SlidingWindowDataset via
    .to(torch.float32, copy=True) — one copy instead of clone + to,
    and the cast runs in dataloader worker processes (no GIL).

_open_mmap_buffer gains an array_key kwarg so the fg_mask open path
can round-trip the mask's dtype instead of inheriting the source
array's dtype (silent mismatch on uint8 masks vs float32 data).

Tests:
  * test_mmap_preload_preserves_native_dtype_and_casts_on_read —
    uint16 zarr end-to-end: buffer stays uint16, sampled batch is
    float32.
  * test_mmap_preload_fg_mask_preserves_native_dtype — uint8 fg_mask
    buffer stays uint8, sampled batch["fg_mask"] is float32.

Subject: [PATCH 103/311] refactor(data): tighten array_key sentinel, drop
 WHAT-comments in tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two simplify cleanups on top of 8b2332c:

* _open_mmap_buffer: replace `array_key or self.array_key` with an
  explicit `is not None` check so an empty-string override can't
  silently fall through to self.array_key.
* test_hcs.py: drop two WHAT-comments in
  test_mmap_preload_fg_mask_preserves_native_dtype — the assertion
  and shape literal already carry that information.

Subject: [PATCH 104/311] refactor(configs): rename runtime_single_gpu to
 runtime_shared
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The profile's content has nothing single-GPU-specific — just srun +
cleanup_tmp + generic env vars (PYTHONUNBUFFERED, NCCL_DEBUG,
PYTHONFAULTHANDLER). Every leaf composes it, including the 4-GPU
unext2 leaf, which reads as self-contradictory. Rename to
runtime_shared.yml and update the file-header comment.

Mechanical rename: 1 file renamed + 15 edits (14 benchmark leaves
base: list + BENCHMARK_CONFIG_SCHEMA.md references). No behavior
change: composition resolves identical launcher.runtime and
launcher.env values. Benchmark equivalence tests pass unchanged.

First step of a broader ownership cleanup that splits topology
(trainer.accelerator/devices/strategy/num_nodes) into its own
recipe layer. See plan at ~/.claude/plans/vectorized-sleeping-clock.md.

Subject: [PATCH 105/311] feat(configs): add topology recipes under dynacell
 and cytoland
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduces a cross-cutting topology layer that owns
trainer.{accelerator, strategy, devices, num_nodes}. Two recipes per
app: single_gpu.yml (strategy: auto, devices: 1) and ddp_4gpu.yml
(strategy: ddp, devices: 4).

Dynacell and cytoland each get their own copies because CLAUDE.md
forbids cross-application imports (applications/... → applications/...
is not allowed; the dependency flow is applications/ → packages/).
The two apps' topology recipes are byte-identical today but are
independently owned so either app can diverge without entangling the
other.

Additive only — no consumers yet. Commit 3 will migrate all fit/predict
leaves in both apps to compose these, strip trainer.devices from
benchmark hardware profiles, and unify fit_1gpu/fit_4gpu/fit_fm_4gpu
into a single fit.yml per app.

Subject: [PATCH 106/311] refactor(configs): unify fit/predict trainer recipes,
 own topology separately
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Dynacell and cytoland previously had three+ trainer recipes each
(fit_1gpu, fit_4gpu, fit_fm_4gpu, predict_gpu) that mingled trainer
topology (devices/strategy/num_nodes/accelerator), mode invariants
(logger/callbacks/seed), and model-adjacent defaults (precision,
max_epochs). Hardware profiles redundantly set trainer.devices too,
creating silent-drop-DDP traps when recipe+hardware got paired
inconsistently. This commit untangles the layers:

* **New topology recipes** (from the prior commit, now consumed):
    recipes/topology/single_gpu.yml  -> accelerator/strategy/devices/num_nodes
    recipes/topology/ddp_4gpu.yml    -> same keys for 4-GPU DDP
  Dynacell and cytoland each own a parallel copy (CLAUDE.md forbids
  cross-application imports).

* **Unified fit/predict trainer recipes** per app:
    recipes/trainer/fit.yml    -> mode invariants: seed, logger, callbacks,
                                  log_every_n_steps, enable_checkpointing.
                                  Dynacell pins project=dynacell; cytoland
                                  pins project=cytoland.
    recipes/trainer/predict.yml -> precision=32-true, HCSPredictionWriter
                                  callback placeholder, return_predictions=false.
  Neither recipe sets topology or model-adjacent precision/max_epochs.

* **Hardware profiles** drop trainer.devices. They now own only
  launcher.sbatch.*. Consumers pair them with a topology recipe.

* **Model overlays** (benchmark) and **leaves** (examples) now compose
  [fit.yml + topology/*.yml] or [predict.yml + topology/*.yml]. Every
  overlay and example sets precision explicitly where it used to be
  inherited — preserves current behavior:
    - celldiff_fit, celldiff_predict, unetvit3d_fit: already bf16-mixed
    - fnet3d_paper_fit: keeps 32-true (paper reproduction)
    - unext2_fit: adds explicit 16-mixed + max_epochs=200
    - dynacell examples/celldiff/fit.yml: adds bf16-mixed + FM-style
      callback override (every_n_epochs=10, save_top_k=-1)
    - cytoland dynacell-bridge configs: preserve project=dynacell leaf
      override (over cytoland's project=cytoland default)

* **FCMAE pretraining leaves** (cytoland vscyto2d/vscyto3d pretrain.yml)
  keep their leaf-body `strategy: ddp_find_unused_parameters_true`
  scalar-override — wins over topology/ddp_4gpu.yml's plain `ddp`.

* **Intentional behavior delta**: dynacell examples fnet3d/unetvit3d/
  unext2 and the benchmark unext2 leaf gain an explicit WandbLogger
  class_path (previously resolved to Lightning's default
  TensorBoardLogger). Every active SLURM job already uses wandb; this
  aligns the source configs with runtime reality. Leaves that need a
  different logger can override class_path in the body.

* **strategy semantics**: fit_1gpu.yml-derived paths previously composed
  strategy=ddp at devices=1 (functionally equivalent to auto; just
  misleading). topology/single_gpu.yml sets strategy=auto. Lightning
  treats them identically at devices=1.

* **LEGACY deletion**: tools/LEGACY/examples_configs/ was kept as
  read-only historical reference. After this refactor its base: chains
  point at deleted recipes, so it's truly un-runnable. Deleted outright
  per CLAUDE.md's "avoid backwards-compatibility hacks" rule. The
  equivalence tests that composed LEGACY (test_*_leaf_matches_legacy,
  test_fnet3d_paper_leaf_matches_ran_config,
  test_byte_equivalence_sec61b_train_leaf) are replaced with forward-
  looking composition sanity tests.

Equivalence verification against a pre-commit snapshot (35 leaves):
every leaf's trainer.devices/num_nodes/accelerator/precision/max_epochs
matches pre-state (modulo 1-vs-None on num_nodes for predict leaves,
which Lightning already defaults). Intentional deltas (strategy auto,
logger WandbLogger) are spelled out above.

BENCHMARK_CONFIG_SCHEMA.md updated to reference new recipe paths.

-# LEGACY — Dihan's pre-schema CellDiff / UNetViT3D configs
-
-**Reference-only.** `base:` paths were patched post-move from
-`../../../configs/recipes/...` to `../../../../configs/recipes/...` so the
-equivalence test in `tests/test_benchmark_config_composition.py` can still
-compose them, and the `preload:` kwarg was later renamed in place to
-`mmap_preload:` when `HCSDataModule` dropped the ambiguous name. The
-patched files are not intended to be launched directly — use the migrated
-leaves under `configs/benchmarks/virtual_staining/` via
-`submit_benchmark_job.py`.
-
-## Migration map
-
-| Legacy file | New leaf | Equivalence test |
-|---|---|---|
-| `sec61b/fit_celldiff.yml` | `train/er/ipsc_confocal/celldiff.yml` | `test_train_leaf_matches_legacy[er-sec61b]` |
-| `tomm20/fit_celldiff.yml` | `train/mito/ipsc_confocal/celldiff.yml` | `test_train_leaf_matches_legacy[mito-tomm20]` |
-| `nucl/fit_celldiff.yml` | `train/nucleus/ipsc_confocal/celldiff.yml` | `test_train_leaf_matches_legacy[nucleus-nucl]` |
-| `memb/fit_celldiff.yml` | `train/membrane/ipsc_confocal/celldiff.yml` | `test_train_leaf_matches_legacy[membrane-memb]` |
-| `sec61b/predict_celldiff.yml` | `predict/er/ipsc_confocal/celldiff/ipsc_confocal.yml` | `test_predict_leaf_matches_legacy[er-sec61b]` |

-| `sec61b/fit_unext2.yml` | `train/er/ipsc_confocal/unext2.yml` | `test_unext2_train_leaf_matches_legacy` |
-| *(git-removed)* `sec61b/fit_fnet3d_paper.yml` | `train/er/ipsc_confocal/fnet3d_paper.yml` | `test_fnet3d_paper_leaf_matches_ran_config` |
-
-The `fnet3d_paper` leaf has no source file in LEGACY — the earlier
-`fit_fnet3d_paper.yml` was git-removed in commit `42d66d7`. The new leaf
-is verified directly against the LightningCLI config.yaml that Lightning
-saved when the run trained, at
-`/hpc/projects/comp.micro/virtual_staining/models/dynacell/ipsc/sec61b/fnet3d_paper/config.yaml`.
-The equivalent wandb-logged model hyperparameters
-(in project `computational_imaging/dynacell`, run group
-`FNet3D_iPSC_SEC61B_paper`) match across all 9 runs in the group.
-
-### Notes on `fit_unetvit3d.yml`
-
-The legacy file carries two copy-paste bugs from celldiff that jsonargparse
-rejects at parse time:
-
-1. `net_config:` nested under `DynacellUNet`'s `init_args`.
-   `DynacellUNet.__init__` takes `model_config:`, not `net_config:`, so
-   jsonargparse rejects that override. Also redundant with the recipe's
-   `model_config.input_spatial_size`.
-2. `num_log_steps: 10` under `DynacellUNet`'s `init_args`. That kwarg
-   belongs to `DynacellFlowMatching` (CellDiff), not `DynacellUNet`, so
-   jsonargparse rejects it with `Option 'num_log_steps' is not accepted`.
-   Confirmed by an actual fit crash on slurm job 31104787 when the new
-   overlay still carried this field over from celldiff_fit.yml.
-
-The new leaf drops both. Runtime-equivalent in every other field.
-
-## Why kept
-
-These are the source-of-truth hyperparameter reference for the migrated
-benchmark leaves under `configs/benchmarks/virtual_staining/train/` and
-`.../predict/`. The equivalence test
-(`tests/test_benchmark_config_composition.py`) asserts that each migrated
-leaf composes to the same values these files compose to. Delete this tree
-only after:
-
-1. One successful end-to-end `submit_benchmark_job.py` run against a
-   migrated leaf (fit or predict), verified on wandb/disk; and
-2. 2026-06-30 at the earliest.
-
-Whoever deletes this should note both conditions in the commit message.
-
-## Rerunning these configs
-
-Copy them back out to the original location or fix the `base:` paths
-manually. They are preserved exactly as they were when they worked.

From 3fdb7cf85919649dfdc693717dbc2daf2e55bb89 Mon Sep 17 00:00:00 2001
From: Alexandr Kalinin <alxndrkalinin@users.noreply.github.com>
Date: Fri, 17 Apr 2026 17:55:24 -0700
Subject: [PATCH 107/311] refactor: trim WHAT-comments and drop unused
 _strip_reserved in config cleanup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Simplify-pass cleanups on top of the topology/trainer-recipe refactor:

* test_benchmark_config_composition.py: drop the history-paragraph in
  the module docstring (commit log records the LEGACY removal), drop
  the `_strip_reserved` helper (tests never touch launcher/benchmark
  keys — only trainer/data), tighten the unext2 regression-guard
  docstring from a pre-refactor narrative to a one-line WHY.
* dynacell + cytoland recipes/trainer/fit.yml: drop redundant
  "Unified fit trainer recipe" banner; keep the ownership-boundary
  orientation block.
* recipes/topology/single_gpu.yml (both apps): tighten WHY ("plain
  ddp at devices=1 would add pointless process-group overhead").
* hardware_h200_single.yml: rephrase the dangling trainer.devices
  line to reference the new topology recipe boundary.
* cytoland dynacell-bridge configs + pretrain configs: collapse
  three-line comments to one-line WHYs.
* applications/dynacell/README.md: drop the tools/LEGACY/ bullet
  (LEGACY was deleted in the prior commit).

Subject: [PATCH 108/311] refactor(tools): drop undocumented stdout echo from
 --dry-run
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously, bare `--dry-run` (no --print-*) wrote the rendered sbatch
to both disk AND stdout. The stdout echo was nowhere in the help text
and duplicates --print-script's behavior when --dry-run is combined
with it. Use --print-script alongside --dry-run to get both the disk
artifact and the stdout preview; use --print-script alone for a
preview-only run that writes nothing.

Existing tests still pass — none covered the echo path.

Subject: [PATCH 109/311] refactor(cli): log warning when composed-config parse
 fails

_maybe_compose_config silently swallowed OSError/yaml.YAMLError so
LightningCLI's diagnostic would fire instead. That's the right
behavior, but silently discarding the original exception makes
debugging missing/malformed configs harder. Add a logger.warning
with the path and exception text before the early return.

Subject: [PATCH 110/311] perf(compose): memoize YAML parsing in
 load_composed_config

A recipe file that appears in multiple leaves' base: chains (hardware
profiles, shared runtime, topology recipes, trainer recipes) was
re-opened and re-parsed once per reference. For the current benchmark
schema depth (~4 levels, 35 leaves) this is milliseconds of wasted
work per composition, but the overhead scales with leaf fan-out.

Cache the raw yaml.safe_load output in a module-level lru_cache keyed
by the fully-resolved Path, then deep-copy the cached dict before
returning so callers can mutate (pop "base", deep_merge) without
poisoning subsequent cache hits. lru_cache(maxsize=256) is plenty for
the current recipe count with headroom for future growth.

Subject: [PATCH 111/311] ci: add dynacell benchmark-config tests to the test
 matrix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously, applications/dynacell/tests/ was invisible to GitHub
Actions — dynacell is absent from the test-applications matrix
(only dynaclr, cytoland, airtable, qc run there). The benchmark
schema equivalence and submit-tool tests would silently regress
without PR gating.

Adds a scoped test-dynacell-configs job that:
- syncs only the base dependencies + test group (no --all-extras)
- runs tests/test_benchmark_config_composition.py and
  tests/test_submit_benchmark_job.py

Full dynacell suite is intentionally out of scope here: the eval
extra pulls cellpose/transformers/cubic/dynaclr/segmenter-model-zoo/
microssim-from-git, several of which don't resolve cleanly on
ubuntu-latest without GPU-adjacent toolchain setup. That can be
added incrementally as tests are audited for CI-safety.

Subject: [PATCH 115/311] fix(tools): set umask 0002 so benchmark run outputs
 are group-writable

Output dirs on shared project paths (wandb, Lightning ModelCheckpoint,
HCSPredictionWriter, resolved/, slurm/) inherited whatever the caller's
login-shell umask was, so collaborators sometimes landed on 0755 trees
and had to chmod manually. Pin umask to 0002 in both submission paths:
the sbatch template for compute-node writes, and submit() for the
login-node artifacts it creates before sbatch runs.

Subject: [PATCH 116/311] refactor(cli): let config read errors propagate in
 _maybe_compose_config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The warn-and-return path added in e0f5c00 just doubled the diagnostic —
LightningCLI re-opens the same file and emits its own error anyway.
Removing the catch lets the native FileNotFoundError / PermissionError /
yaml.YAMLError surface cleanly with the path and line info baked in,
aligning with CLAUDE.md's "prefer raising errors" rule.

 violations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prerequisite cleanup so follow-up feat commits can pass the pre-commit
hook. Renames ambiguous single-letter `O` → `ov` in predict_sliding_window
and wraps two over-long error messages in predict_step. No behavior change.

Subject: [PATCH 119/311] feat(engine): add encoder_only FCMAE load to
 DynacellUNet
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors the canonical vs_test/finetune_3d.py:load_model recipe and the
cytoland FcmaeUNet._load_encoder_weights pattern (CLAUDE.md bans dynacell
importing from cytoland, so the logic is replicated).

Extends the architecture registry with "fcmae" → FullyConvolutionalMAE
and adds an encoder_only constructor flag that, when paired with
ckpt_path, loads only the model.encoder.* weights and leaves the
decoder/head at fresh init. Intended for FCMAE-pretrained finetune leaves.

Subject: [PATCH 120/311] feat(configs): add FCMAE-family benchmark pair on
 ER/SEC61B
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a shared fcmae_vscyto3d_fit.yml overlay and two leaves that are
identical except for encoder initialization:

- fcmae_vscyto3d_scratch.yml: FullyConvolutionalMAE(pretraining=False),
  random init — paper-adjacent scratch baseline.
- fcmae_vscyto3d_pretrained.yml: same class, loads encoder weights from
  the published VSCyto3D FCMAE ckpt (400 ep on HEK + A549 + iPSC) via
  DynacellUNet(encoder_only=True, ckpt_path=...).

Isolates the pretrained-vs-scratch comparison to encoder init alone.
Relabels the existing timm-backed unext2.yml leaf (model_name becomes
unext2_timm_scratch) so future lineage tables name honestly; save_dir
and logger.name stay unchanged so the in-flight job's artifacts keep
writing to the same location. UNEXT2_VS_FCMAE_CLASSES.md explains the
class split and why unext2 is not the apples-to-apples scratch control.

+# `UNeXt2` vs `FullyConvolutionalMAE`: one paper architecture, two PyTorch models
+
+Reconciling the Cytoland paper
+([Liu et al., *Nat. Mach. Intell.* 2025, doi:10.1038/s42256-025-01046-2](https://doi.org/10.1038/s42256-025-01046-2))
+with the two independent Python classes that claim to implement its
+"UNeXt2" architecture. Needed while planning FCMAE-pretrained finetune
+runs on `dynacell-models`, where the naming otherwise misleads.
+
+## TL;DR
+
+- The paper (Fig 1b ↔ 1c) describes **one** architecture — "UNeXt2" —
+  trained twice: first self-supervised via FCMAE masking, then supervised
+  with the pretrained encoder transferred in.
+- The code has **two independent Python classes** claiming to implement
+  that architecture: `viscy_models.unet.unext2.UNeXt2` (timm-backed) and
+  `viscy_models.unet.fcmae.FullyConvolutionalMAE` (custom masked
+  re-implementation). They have **incompatible state_dicts** AND
+  **structurally different models** — verified below by parameter count.
+- The split predates the packaging refactor and predates the `UNeXt2`
+  rename. The supervised path started as `viscy/unet/networks/Unet21D.py`
+  in August 2023, and the masked FCMAE path was added as
+  `viscy/unet/networks/fcmae.py` in April 2024. The key reason for the
+  second implementation was masked pre-training: `timm.models.convnext`
+  did not expose the per-block masking hooks needed by FCMAE, so Ziwen
+  Liu (paper lead author) wrote a standalone masked ConvNeXtV2 encoder.
+  Some of the larger architectural divergence we see today is current
+  implementation reality, not necessarily the original motivation.
+- In the paper's published workflow,
+  **`FcmaeUNet(architecture="fcmae")` is used for BOTH the self-supervised
+  pretrain AND the supervised finetune** (the `pretraining` boolean
+  toggles masking in `forward`). The timm-backed `UNeXt2` class is
+  **never** used with FCMAE-pretrained weights.
+- The checkpoint matters. The published and current fine-tuning script
+  `/hpc/mydata/alex.kalinin/vs_test/finetune_3d.py` loads
+  `/hpc/projects/virtual_staining/models/mehta-lab/VSCyto3D/fcmae.ckpt`,
+  and that checkpoint **does** load into the current
+  `FullyConvolutionalMAE`/`FcmaeUNet` path. The other checkpoint explored
+  during planning,
+  `/hpc/projects/comp.micro/virtual_staining/models/fcmae-3d/fit_v1/.../last.ckpt`,
+  does **not** load into the current packaged FCMAE class because its
+  stem tensor shapes differ.
+- **Setting `pretraining=False` on the FCMAE model does not produce the
+  same PyTorch model as `UNeXt2`.** They differ in stem (LayerNorm or
+  not), head (trainable Conv3d or pure PixelShuffle), num_blocks (6 vs 8),
+  total parameter count (32.4M vs 32.1M), and block forward numerics.
+  They are the same *conceptual* architecture from the paper's pen-and-
+  paper diagram, not the same PyTorch hypothesis class.
+- So the currently-running dynacell `unext2.yml` job (timm-backed
+  `UNeXt2`) is a valid "from-scratch ConvNeXtV2-tiny baseline" but is
+  **not** the apples-to-apples random-init control for a FCMAE-pretrained
+  finetune. For a clean comparison, both runs must be
+  `FullyConvolutionalMAE(pretraining=False)`.
+
+## What the paper says (Fig 1b ↔ 1c)
+
+One architecture, called **UNeXt2** =
+*3D projection stem + 2D encoder + 2D decoder + 3D head*.
+Trained twice:
+
+- **1b (FCMAE pretrain):** masked input, reconstruction loss on masked
+  regions.
+- **1c (virtual-staining supervised):** same net, pretrained encoder
+  weights copied in, decoder trained from scratch, phase→fluor regression.
+
+Unambiguous — it's the *same* network, two training regimes.
+
+## What the code actually has
+
+Two independent classes under `packages/viscy-models/src/viscy_models/unet/`:
+
+| | `unext2.py::UNeXt2` | `fcmae.py::FullyConvolutionalMAE` |
+|---|---|---|
+| Encoder impl | `timm.create_model("convnextv2_tiny", features_only=True)` with `stem_0 → nn.Identity()`, separate `UNeXt2Stem` prepended | Custom `MaskedMultiscaleEncoder` built from `MaskedConvNeXtV2Block` + `MaskedAdaptiveProjection` — from-scratch re-implementation of ConvNeXtV2 with masking hooks in every block |
+| Stem params | `stem.weight`, `stem_1.weight` | `encoder.stem.conv3d.*`, `encoder.stem.conv2d.*`, `encoder.stem.norm.*` |
+| Block params | `encoder_stages.stages_0.blocks.0.conv_dw.weight`, `.norm.weight` | `encoder.stages.0.blocks.0.dwconv.weight`, `.layernorm.weight` |
+| Masking hook | none — inference only | `unmasked: BoolTensor \| None` kwarg threaded through every block's `forward` |
+| State_dict interchange | — | **Not compatible.** No adapter exists in the codebase. |
+
+## Why `pretraining=False` does **not** collapse the gap
+
+The natural intuition is that `FullyConvolutionalMAE(pretraining=False)`
+with `mask_ratio=0.0, unmasked=None` degenerates to a plain ConvNeXtV2
+forward pass and should therefore be structurally equivalent to `UNeXt2`
+(both wrap ConvNeXtV2-tiny). Probing both classes at matching config
+(`backbone=convnextv2_tiny, in_stack_depth=15, stem_kernel_size=[5,4,4],
+decoder_conv_blocks=2, in_channels=1, out_channels=1, drop_path_rate=0.1`)
+shows that is not the case:
+
+```
+UNeXt2                     total params: 32,426,277   num_blocks: 6
+FullyConvolutionalMAE(p=F) total params: 32,148,528   num_blocks: 8
+  delta: -277,749 (-0.86%)
+
+UNeXt2 children                      FCMAE(p=F) children
+  encoder_stages: 27,860,256           encoder:  27,857,856   (stem folded in)
+  stem:                2,592           decoder:   4,290,672
+  decoder:         4,561,616           head:             0
+  head:                1,813           (no separate stem module)
+
+UNeXt2 stem has LayerNorm?   False
+FCMAE encoder.stem has norm? True
+```
+
+Concrete structural differences that survive `unmasked=None`:
+
+1. **Stem normalization.** `MaskedAdaptiveProjection` applies
+   `nn.LayerNorm(out_channels)` after the 3D→channels projection.
+   `UNeXt2Stem` is just `Conv3d + reshape` with no normalization. The
+   first activations handed to stage 0 have different statistics in the
+   two classes.
+
+2. **Head is structurally different.** `UNeXt2.head` is
+   `PixelToVoxelHead` = `UpSample(pixelshuffle) + Conv3d + icnr_init +
+   PixelShuffle` (1,813 trainable params).
+   `FullyConvolutionalMAE.head` defaults to `PixelToVoxelShuffleHead` =
+   a pure `UpSample(pixelshuffle)` (**0 trainable params**) and pushes
+   all channel math into the decoder's last stage. Not the same output
+   pathway. `FullyConvolutionalMAE(head_conv=True, ...)` would select
+   `PixelToVoxelHead` but with different channel wiring than `UNeXt2`.
+
+3. **`num_blocks` differs (6 vs 8).** Consumed by
+   `DynacellUNet._make_divisible_pad` / `VSUNet._make_divisible_pad` to
+   require input spatial dims divisible by `2**num_blocks`. UNeXt2 needs
+   multiples of 64; FCMAE needs multiples of 256. A YX patch size that
+   validates for one will not necessarily validate for the other.
+
+4. **Block forward numerics diverge.** `MaskedConvNeXtV2Block.forward` is
+   `shortcut → dwconv → masked_patchify(x, unmasked=None) (flatten to
+   BLC) → LayerNorm on channels-last → GlobalResponseNormMlp(unsqueeze→
+   squeeze) → masked_unpatchify (reshape back to BCHW) → drop_path +
+   shortcut`. Timm's `ConvNeXtV2Block.forward` is `shortcut → conv_dw →
+   norm (as LayerNorm2d in channels-first, or permute-for-channels-last
+   if `use_conv_mlp`) → mlp → gamma-scale (LayerScale when
+   `ls_init_value` is set) → drop_path + shortcut`. The masked block
+   always pays the patchify↔unpatchify reshape even in the no-mask case;
+   timm stays channels-first throughout; the LayerScale `gamma`
+   parameter is present in timm and absent in the masked block. Given
+   identical parameter tensors the two forward passes would not produce
+   bit-identical outputs.
+
+5. **Parameter count delta of 277,749 is structural, not initialization
+   noise.** Sources: the stem LayerNorm (+2 params), the head/decoder
+   partition difference (UNeXt2 head 1,813 + decoder 4,561,616 = 4,563,429
+   vs FCMAE head 0 + decoder 4,290,672 = 4,290,672, delta 272,757 in the
+   decoder-plus-head block), and the block-level presence/absence of the
+   LayerScale `gamma` parameter.
+
+Conclusion: these are the same *conceptual* architecture from Fig 1 but
+not the same PyTorch hypothesis class. Training one from scratch does
+not yield an equivalent starting point to training the other from
+scratch — different parameter sets, different normalization pathways,
+different forward numerics.

+## Archaeology: why two on pre-refactor `main`
+
+History on `origin/main` (all commits by Ziwen Liu, paper's lead author):
+
+| SHA | Date | PR | Change |
+|---|---|---|---|
+| `b4ec13c` | 2023-08-30 | #37 | `viscy/unet/networks/Unet21D.py` introduced — supervised ConvNeXt-backed virtual-staining model with custom 3D stem and 3D head. This is the ancestor of today's `UNeXt2` class. |
+| **`0536d29`** | **2024-04-08** | **#67** | **`viscy/unet/networks/fcmae.py` added as a new file**, commit titled "Masked autoencoder pre-training for virtual staining models". Squashed commit text explicitly shows the new masked encoder work: `draft fcmae encoder` → `add stem to the encoder` → `wip: masked stem layernorm` → `wip: patchify masked features for linear` → `use mlp from timm`. This was a new implementation, not a refactor of `Unet21D.py`. |
+| `9a0fe64` | 2024-06-11 | #84 | `viscy/unet/networks/Unet21D.py` → `viscy/unet/networks/unext2.py`; class lineage rebranded to `UNeXt2`. `fcmae.py` remained a separate file. |
+
+**Why a standalone class instead of reusing Unet21D / UNeXt2?**
+`timm.models.convnext.ConvNeXtBlock` has no per-block mask argument —
+its `forward` computes `dwconv → norm → mlp → residual` with no hooks
+for zeroing out masked activations or for sparse-gradient propagation.
+FCMAE requires all three: masked dwconv input,
+`masked_patchify`/`masked_unpatchify` around the pointwise MLP (so the
+MLP only runs on visible patches and GRN statistics aren't polluted by
+masked zeros), and drop-path/shortcut that skip the masked regions. The
+clean path was to write `MaskedConvNeXtV2Block` from scratch with those
+hooks baked in; monkey-patching timm's ConvNeXtBlock would have been
+fragile across timm upgrades.
+
+**Why didn't the two codepaths converge later?**
+There is no evidence that state_dict compatibility between the two
+classes was ever a goal. The paper and the published scripts use the
+FCMAE-side class for FCMAE pre-train and FCMAE-initialized finetune, and
+use the supervised/timm side for scratch supervised baselines. So the
+code never needed a translation layer to support the published workflow.
+That explains the persistent key mismatch: `UNeXt2` inherits timm-style
+naming (`stages_N`, `conv_dw`, `norm`), whereas the masked path uses its
+own naming (`stages.N`, `dwconv`, `layernorm`). No adapter or
+equivalence tests were added because the two state_dicts were not
+expected to cross in production.
+
+## How the paper's own workflow handles the split
+
+The published fine-tuning path as currently exercised by
+`/hpc/mydata/alex.kalinin/vs_test/finetune_3d.py` uses
+**`FcmaeUNet` for both regimes**:
+
+```python
+unet = FcmaeUNet(model_config=dict(
+    in_channels=1, out_channels=2,
+    encoder_blocks=[3, 3, 9, 3], encoder_drop_path_rate=0.1,
+    dims=[96, 192, 384, 768], decoder_conv_blocks=2,
+    stem_kernel_size=(5, 4, 4), in_stack_depth=15,
+    pretraining=False,        # supervised mode, no masking in forward
+))
+
+if encoder_only:
+    encoder_weights = {
+        k.split("model.encoder.")[1]: v
+        for k, v in pretrained["state_dict"].items()
+        if "encoder" in k
+    }
+    unet.model.encoder.load_state_dict(encoder_weights)   # same class, trivial load
+```
+
+`FcmaeUNet` wraps `FullyConvolutionalMAE`. The `pretraining` flag inside
+`model_config` toggles masking in `forward`:
+- `pretraining=True`  → masked input + reconstruction loss (Fig 1b regime)
+- `pretraining=False` → no masking + supervised regression loss (Fig 1c regime)
+
+Weight transfer between the two regimes is **trivial** because both
+sides are `FullyConvolutionalMAE` — identical parameter names throughout.
+No key translation, no adapter needed.
+
+On pre-refactor `main`, the encoder-only transfer lived in *user code*,
+inside the fine-tune script, not in the library. The
+`encoder_only` / `_load_encoder_weights` helper on
+`cytoland.engine.FcmaeUNet` was added later on the modular branch to
+formalize that same pattern.
+
+## Implications for our benchmarks
+
+The two Python classes serve distinct roles:
+
+- `FullyConvolutionalMAE` (via `FcmaeUNet`) — the FCMAE pretrain ⇄
+  finetune codepath. This is what the paper's Fig 1b/1c workflow uses,
+  on both sides.
+- `UNeXt2` — from-scratch supervised training *without* FCMAE
+  pretraining. Used for baselines / ablations that skip FCMAE entirely.
+
+**"UNeXt2" in the paper refers to the conceptual architecture, not the
+Python class of the same name.** The Python class `UNeXt2` has never
+been used with FCMAE-pretrained weights in any checked-in script or
+benchmark — not on main, not on this branch, not in the published
+artifacts.
+
+Dynacell's currently-running from-scratch job
+(`benchmarks/virtual_staining/train/er/ipsc_confocal/unext2.yml`, SLURM
+31122607) uses `DynacellUNet(architecture="UNeXt2")` — the timm-backed
+class. That's a valid "from-scratch baseline with a timm ConvNeXtV2-tiny
+encoder," but it trains a structurally different model (stem without
+LayerNorm, Conv3d-backed head, 277k extra params, num_blocks=6) from
+the FCMAE codepath. It is **not** the apples-to-apples random-init
+control for an FCMAE-pretrained-init finetune: it's a different
+hypothesis class that happens to share the paper's conceptual name. A
+paper-faithful comparison requires both runs to use
+`FullyConvolutionalMAE(pretraining=False)`.
+
+### Recommended benchmark layout for dynacell
+
+Do **not** treat the current `unext2.yml` leaf as the random-init control
+for an FCMAE-pretrained run. Keep it, but label it honestly as the
+timm-backed supervised UNeXt2 baseline.
+
+For the FCMAE question, add a separate pair of leaves that use the same
+class on both sides:
+
+- `fcmae_vscyto3d_scratch`
+- `fcmae_vscyto3d_pretrained`
+
+Those two leaves should be identical except for encoder initialization:
+
+- same `FullyConvolutionalMAE(pretraining=False)` / `FcmaeUNet`-style model
+- same decoder config
+- same LR / batch / crops / epochs
+- only `encoder_only + ckpt_path` differs
+
+Use the compatible checkpoint from the latest fine-tuning script:
+
+- `/hpc/projects/virtual_staining/models/mehta-lab/VSCyto3D/fcmae.ckpt`
+
+Do **not** use the incompatible checkpoint:
+
+- `/hpc/projects/comp.micro/virtual_staining/models/fcmae-3d/fit_v1/lightning_logs/pretrain-neuro-aic-hek-200ep_maxsize_fry1_resume4/checkpoints/last.ckpt`
+
+### Alternative paths
+
+1. **Use `FullyConvolutionalMAE(pretraining=False)` for both the
+   random-init and FCMAE-pretrained-init leaves** (retire the
+   timm-backed `unext2.yml` leaf, or re-frame it as a separate
+   baseline). Paper-faithful. The only axis of comparison between the
+   two new leaves is the encoder init.
+2. **Keep the existing timm-backed `unext2.yml` as an informal baseline**,
+   add a `FullyConvolutionalMAE(pretraining=False)` FCMAE-finetune leaf
+   on the side. Comparison has an architecture asterisk — same paper
+   concept, structurally different PyTorch models (param count, stem,
+   head, num_blocks).
+3. **Unify the two classes in `viscy-models`** (replace `UNeXt2`'s timm
+   encoder with a shared backbone that supports optional masking, or
+   make the timm encoder's state_dict transformable to FCMAE naming via
+   a one-shot adapter). Clean but a separate `viscy-models` PR.

Subject: [PATCH 121/311] =?UTF-8?q?test(engine,configs):=20cover=20encoder?=
 =?UTF-8?q?=5Fonly=20load=20+=20scratch=E2=89=A1pretrained=20invariant?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three engine tests:
- encoder_only loads model.encoder.* from a wrapped ckpt and leaves the
  decoder at fresh init (restricted to randomly-initialized decoder
  params — LayerNorm constants cannot prove the negative).
- encoder_only=True without ckpt_path raises.
- encoder_only on a non-fcmae architecture raises.

One composition regression test:
- test_fcmae_pretrained_differs_from_scratch_only_in_encoder_init guards
  that the two FCMAE leaves resolve to byte-equal configs after stripping
  encoder_only, ckpt_path, and the per-leaf identifier/path fields.
  Protects the scientific invariant underlying the comparison from silent
  drift in lr/loss/crops/augs/model_config/trainer/epochs.

Also adds the two new leaves to TRAIN_LEAVES so test_train_leaf_composes
exercises them.

Subject: [PATCH 122/311] fix(evaluation): declare feature_extractor schema in
 eval.yaml

The base eval config had no feature_extractor block, so every invocation
with compute_feature_metrics=true had to either use + prefixes on each
override or rely on a non-standard key=@file.yml syntax that Hydra
actually stores as a literal string. The README showed a mix of the two
that does not run as written.

Add dinov3/dynaclr/encoder fields as ??? (MISSING) so:
  - runs with feature metrics off pass through (lazy resolution)
  - the normal CLI override form works (no +)
  - forgetting a field raises MissingMandatoryValue at access time with
    the full key path, instead of AttributeError deep in pipeline.py

Fix the README bash blocks to match: drop the +, replace the fake
=@file.yml with the honest inline-dict form for the encoder kwargs.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Every benchmarked eval invocation was restating the same 6+ fields for
the same (organelle, marker, dataset, microscope) tuple. Add packaged
Hydra groups so callers can select a named combination instead:

  uv run dynacell evaluate target=er_sec61b predict_set=ipsc_confocal     io.pred_path=… save.save_dir=…

Groups:
- target/{er_sec61b,mito_tomm20,membrane,nucleus}: target_name, gt_path,
  cell_segmentation_path, and per-organelle {gt,pred}_channel_name
  (Structure/Structure_prediction for ER+mito; Membrane/Membrane_prediction
  for membrane; Nuclei/Nuclei_prediction for nucleus — verified against
  the actual OME-Zarr channel_names).
- predict_set/ipsc_confocal: pixel_metrics.spacing for this microscope.
- feature_extractor/dinov3/lvd1689m: canonical DINOv3 ViT-L/16.
- feature_extractor/dynaclr/default: canonical organelle-sensor DynaCLR
  checkpoint and 8-field ContrastiveEncoder kwargs (convnext_tiny, 768-d
  embedding). Encoder values sourced from the pre-refactor dynaclr repo
  (czbiohub-sf/dynacell @ a9d5c5a) so we don't speculate on architecture.

Declared as `optional <group>: null` in eval.yaml's defaults so
CLI forms that don't select groups continue to work (backward
compatible). A `- optional benchmark: null` entry is added now so Phase 3
benchmark leaves land without touching eval.yaml again.

precompute.yaml inherits the defaults list transitively — verified —
so `dynacell precompute-gt target=er_sec61b …` also works.

End-to-end smoke (limit_positions=1) against sec61b_fnet3d.zarr
produces real pixel/mask metric CSVs with sensible values (PCC 0.63,
Dice 0.14 on one random FOV).

 `dynacell evaluate` is a Hydra entrypoint. Override any field on the CLI with `key=value`.
 
+Paths and settings that belong to a (target, marker, dataset) combination live in
+named config groups under `_configs/`, so most invocations only need to select the
+right group and point at the prediction / output paths.
+
+### Config groups
+
+| Group | Options | What it sets |
+|---|---|---|
+| `target` | `er_sec61b`, `mito_tomm20`, `membrane`, `nucleus` | `target_name`, `io.gt_path`, `io.cell_segmentation_path`, `io.gt_channel_name`, `io.pred_channel_name`. |
+| `predict_set` | `ipsc_confocal` | `pixel_metrics.spacing`. |
+| `feature_extractor/dinov3` | `lvd1689m` | `feature_extractor.dinov3.pretrained_model_name`. |
+| `feature_extractor/dynaclr` | `default` | `feature_extractor.dynaclr.checkpoint` and 8-field `encoder` dict. |

+declared as `optional` in `eval.yaml`).
+
+`target_name` ∈ {`nucleus`, `membrane`, `nucleoli`, `lysosomes`, `er`, `mitochondria`} — selects the `aicssegmentation` workflow. The first four map 1:1 with the `target` group's
+`target_name` field; `nucleoli` and `lysosomes` have no ready-made target group yet
+and must be set directly (`target_name=…`).
+
 ### Minimal example — pixel + mask metrics only
 
 ```bash
 uv run dynacell evaluate \
-  target_name=er \
+  target=er_sec61b \
+  predict_set=ipsc_confocal \
   io.pred_path=/hpc/projects/virtual_staining/training/dynacell/ipsc/predictions/fnet3d_sec61b.zarr \

   save.save_dir=/hpc/projects/virtual_staining/training/dynacell/ipsc/predictions/eval_fnet3d_sec61b
 ```

Subject: [PATCH 124/311] feat(configs): bump fcmae_vscyto3d fit overlay lr to
 0.0004

Matches the retuned unext2_fit.yml Run 4 baseline so the pretrained-vs-
scratch FCMAE comparison runs at the same learning rate as the
timm-backed unext2 reference, on the same bs=32/z=20 data pipeline. The
canonical vs_test/finetune_3d.py recipe uses 2e-4 but that's from a
fast_dev_run invocation; the production VSCyto3D pretrain batch/lr is
not recorded in the reference script, so matching the unext2 baseline
is the more defensible choice for a direct benchmark comparison.

Subject: [PATCH 125/311] feat(dynacell): add eval_gpu extra with cupy-cuda12x
 + cucim-cu12
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Evaluation code under dynacell/evaluation/{metrics,io,spectral_pcc/evaluate}
calls cubic.cuda.ascupy for GPU-backed resolution, feature, and spectral
metrics, but cubic itself declares zero dependency on cupy/cucim — it
lazy-imports them and silently falls back to CPU with a warning, then
raises "GPU requested but not available" at call time when CUDA is
actually requested.

Add a new eval_gpu optional extra pinning cupy-cuda12x + cucim-cu12 (the
torch 2.10 + CUDA 12.8 runtime already used in dynacell training) so
`uv sync --extra eval_gpu` installs a working GPU metrics stack. Tighten
_require_cubic() in metrics.py and io.py to probe cupy/cucim imports and
raise an actionable ImportError naming the extra instead of the old
misleading "pip install cubic-s2" message (cubic was already installed;
the missing bits were cupy and cucim).

Subject: [PATCH 126/311] docs(evaluation): drop redundant
 cell_segmentation_path override in example

The feature-metrics CLI example passed io.cell_segmentation_path even
though the target=er_sec61b group already sets it; the paragraph below
the snippet then said "the target group already sets this", contradicting
its own example. Rewrite the example to rely on the group value and keep
the paragraph as a short reminder that the field is required once feature
metrics are on.

Subject: [PATCH 127/311] fix(evaluation): fail loud on missing channels, skip
 empty metric files

Two cleanup items surfaced during Phase 2 review:

1. io.gt_channel_name and io.pred_channel_name had defaults of "target"
   and "prediction" in eval.yaml. Neither string matches any real zarr
   channel produced by the predict pipeline (GT zarrs use Structure /
   Membrane / Nuclei; predictions use <channel>_prediction). A user
   running eval without selecting a target group would get a confusing
   iohub ValueError about a missing channel mid-pipeline. Change both
   defaults to ??? so Hydra raises MissingMandatoryValue at compose
   time with a clear path. Target groups override the ??? with real
   channel names; CLI overrides work as before.

2. save_metrics skipped writing only when a metrics list was None, but
   evaluate_predictions always initializes all_feature_metrics = []
   (never None). With compute_feature_metrics=false the pipeline still
   wrote a 0-byte feature_metrics.csv and feature_metrics.npy, and the
   CSV was unreadable (pandas EmptyDataError). Guard on falsiness so an
   empty list also skips writes.

Subject: [PATCH 128/311] feat(evaluation): add benchmark eval leaves mirroring
 predict tree
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Canonical evaluations for each benchmark (organelle × model × predict_set)
were spread across ad-hoc CLI invocations with drift risk — every person
running a benchmark eval had to re-type paths, spacing, channel names,
and feature-extractor kwargs. Pin each canonical run as a Hydra config
group leaf under _configs/benchmark/<org>/<train_set>/<model>/<predict_set>.yaml
so that:

  uv run dynacell evaluate benchmark=er/ipsc_confocal/celldiff/ipsc_confocal

runs the canonical ER-CellDiff eval against the matching predict output
with feature metrics, caching, and save paths all resolved from config.

Each leaf is a 15-line YAML that `override`s the four Phase 2 groups
(target, predict_set, feature_extractor/{dinov3,dynaclr}) and sets the
three run-level values: io.pred_path (matching the predict leaf's
output_store), io.gt_cache_dir, save.save_dir. CLI overrides still
compose on top (e.g. limit_positions=1 for smoke tests).

Initial set mirrors the predict tree one-to-one:
(er, membrane, mito, nucleus) × (celldiff, unetvit3d) = 8 leaves.
All eight verified by Hydra compose (target_name, gt/pred channels,
spacing, encoder kwargs, pred_path all resolve); the er/celldiff leaf
additionally verified end-to-end on a single position against
sec61b_celldiff_iterative.zarr (54s, complete pixel+mask outputs).

Leaves live inside the package — not alongside predict/train leaves at
configs/benchmarks/virtual_staining/ — because Hydra needs every group
file on one search path anchored at @hydra.main(config_path='_configs').
Both READMEs cross-reference the split.

+**Eval leaves live elsewhere.** Evaluation uses Hydra (not LightningCLI), and
+Hydra needs every group file on a single search path anchored at the package.
+Canonical eval leaves therefore sit inside the dynacell package at
+`applications/dynacell/src/dynacell/evaluation/_configs/benchmark/<org>/<train_set>/<model>/<predict_set>.yaml`
+and are invoked via `dynacell evaluate benchmark=<path>`. See

+### Benchmark eval leaves
+
+Canonical evaluations for the virtual-staining benchmarks are checked in under
+`_configs/benchmark/<organelle>/<train_set>/<model>/<predict_set>.yaml`. Each
+leaf pins every group selection, paths, and the save directory — run one by
+selecting it as the `benchmark` group:

+The current set mirrors the predict benchmark tree one-to-one:

+apply on top (e.g. `limit_positions=1`, `compute_feature_metrics=false`,
+`save.save_dir=/tmp/…` for smoke tests).
+
+Leaves live inside the package (under `_configs/`) rather than alongside the
+predict/train leaves at `configs/benchmarks/virtual_staining/` — Hydra needs
+every referenced group file on a single search path, and
+`@hydra.main(config_path='_configs')` pins that path at the package. See the
+top-level benchmarks README for the predict/train counterparts.

 table

The "Config groups" table listed the four individual groups but omitted
the `benchmark` meta-group added in 817bd6c. Users reading the table
first would miss that `benchmark=<path>` is also a valid (and canonical)
way to select a composition.

hardware_4gpu.yml set --ntasks=1 --gpus=4, so srun launched a single

jobs were actually training on 1 GPU (including the in-flight timm
unext2 baseline 31122607). Split the 32 CPUs across 4 tasks (8 each,
matching num_workers=8).

Subject: [PATCH 132/311] refactor(evaluation): move HPC-bound eval configs out
 of src/
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The dynacell package is meant to be installable and reused by external
users (plug in your own checkpoints/predictions/data, run eval, get
metrics). Our HPC-specific configs — paths under /hpc/projects/..., our
DynaCLR checkpoint, our benchmark-instance leaves — are useless to those
users and shouldn't ship in the wheel.

Split by content:

 - In-package (ships in the wheel): eval.yaml and precompute.yaml schemas,
   plus the path-free reference groups feature_extractor/dinov3/lvd1689m
   (just a HuggingFace name), predict_set/ipsc_confocal (microscope-preset
   spacing), and spectral_pcc/* (diagnostic-tool defaults).
 - Repo checkout only: target/*, feature_extractor/dynaclr/default, and
   all benchmark/** leaves — anything with an HPC path, an internal
   checkpoint, or benchmark-instance values.

The repo-checkout configs live at applications/dynacell/configs/evaluation/
and are exposed to Hydra at compose time via a hydra.searchpath override
prepended (actually appended, so Hydra's argparse doesn't misread it
before -c job) by dynacell.__main__. Editable installs / repo checkouts
see everything; wheel installs without the checkout transparently get
only the schema and must author their own group files via --config-dir.

13 file renames preserved via git mv; renames verified end-to-end by
composing all 4 organelle × 2 model leaves via `dynacell evaluate -c job`,
plus a real pipeline smoke on er/celldiff (39 s, complete pixel+mask
outputs). Wheel-install simulation (moved the external dir aside) shows
clean MissingMandatoryValue errors on schema fields — no stranded
MissingConfigException against group files the user can't see.

Adds _inject_external_configs regression tests to test_cli_routing.py;
existing 202 tests stay green (205 total now).

Subject: [PATCH 133/311] =?UTF-8?q?feat(dynacell):=20enforce=20ntasks=20?=
 =?UTF-8?q?=3D=3D=20gpus=20=3D=3D=20nodes=20=C3=97=20devices=20at=20submit?=

Under SLURM, Lightning's SLURMEnvironment derives world_size from
SLURM_NTASKS, not from trainer.devices. When ntasks < devices, DDP
silently runs with the smaller world_size and only that many GPUs
actually train — the rest sit idle with no warning (caught today on
jobs 31122607 and 31276903, which trained on 1 GPU despite devices=4).

The existing gpus≟devices check missed this entire class of bug
because it never looked at ntasks. Extend the pre-submit validator
plus add a per-leaf regression test so the invariant is enforced
both at submit time and in CI.

Subject: [PATCH 134/311] refactor(__main__): locate external configs via
 pyproject.toml marker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous _external_configs_dir used `.parent.parent.parent` to walk
up from the module to applications/dynacell/. That magic number is fragile
— moving __main__.py into a subpackage would silently compute the wrong
root without any test failing (the dir lookup would just return None,
making all benchmarks invisible).

Replace with a marker-file walk: climb parents until the first
pyproject.toml, then check for configs/evaluation underneath. Self-heals
across module reorganisations and documents intent (find the package
root) rather than mechanism (count directories).

Subject: [PATCH 135/311] feat(configs): add FCMAE scratch/pretrained pair for
 mito/TOMM20
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors the ER/SEC61B pair (fcmae_vscyto3d_{scratch,pretrained}.yml)
on the TOMM20 target so the pretrained-vs-scratch comparison can run
side by side on a second organelle. Both leaves share the overlay, so
they're identical modulo encoder init — extended the scientific-
invariant test to parametrize across organelles and enforce the same
equality for mito.

Subject: [PATCH 136/311] docs(configs): redefine benchmark config schema for
 unified layout

Replace the older Phase-1/Phase-2 training-surface doc with a unified
schema that places train, predict, and eval leaves under one benchmark
cell (<org>/<train_set>/<model>/) and consolidates HPC-bound eval groups
under virtual_staining/shared/eval/. The reorg commit that implements
this lands next.

-# Benchmark Config Schema For Active VisCy Training
-
-This document captures the proposed active benchmark config layout for
-`VisCy/applications/dynacell`, using one-file benchmark configs with embedded
-launcher metadata.
-
-The goal is to support:
-
-- small public example configs
-- real benchmark training configs
-- no drift between training config and SLURM resource settings
-- scalable organization across model families, train sets, targets, and
-  prediction domains
-
-This document covers the active benchmark-training surface for two experiment
-phases:
-
-- Phase 1
-  - target: `er`
-  - train sets:
-    - `ipsc_confocal`
-    - `ipsc_confocal_plus_mantis`
-  - model families:
-    - `fnet3d`
-    - `unext2_scratch`
-    - `unext2_fcmae`
-    - `unetvit3d`
-    - `celldiff`
-- Phase 2
-  - targets:
-    - `mito`
-    - `nucleus`
-    - `membrane`
-  - train sets:
-    - `ipsc_confocal`
-    - `ipsc_confocal_plus_mantis`
-  - model families:
-    - `selected_deterministic`
-    - `celldiff`
-
-Prediction, evaluation, and paper orchestration are downstream stages. They are
-related, but they are not part of this Phase 1 / Phase 2 training numbering.
-
-## Ownership
-
-- `VisCy/applications/dynacell`
-  - owns active runnable benchmark train/predict configs
-  - owns launcher metadata and submission tooling
-  - owns generic `examples/` and reusable `recipes/`
-- `dynacell-paper`
-  - keeps archived historical paper configs
-  - keeps broader benchmark DAG orchestration, paper scripts, and docs
-
-## Target Tree In VisCy
+# Dynacell Benchmark Config Schema
+
+This document defines the target benchmark-config layout for
+`applications/dynacell/configs/benchmarks/virtual_staining/`.
+
+It replaces the older split where:
+
+- train and predict leaves lived under `configs/benchmarks/virtual_staining/`
+- eval leaves and eval target groups lived in a separate top-level
+  `configs/evaluation/` tree
+
+That split is not worth keeping. The benchmark unit is simple:
+
+- choose an organelle
+- train one or more models
+- run prediction on a test set
+- evaluate the resulting prediction store
+
+The filesystem layout should follow that workflow directly.
+
+## Goals
+
+- keep one canonical internal tree for the full virtual-staining workflow
+- make train, predict, and eval leaves sit next to each other
+- keep reusable public schema in the installed `dynacell` package
+- keep HPC-specific benchmark instances out of `src/`
+- make every canonical benchmark run addressable by
+  `(organelle, train_set, model, stage, predict_set)`
+
+## Design Rules
+
+1. `configs/recipes/` stays public and reusable.
+2. `configs/examples/` stays small and generic.
+3. `configs/benchmarks/virtual_staining/` is the canonical internal benchmark tree.
+4. Train, predict, and eval leaves for the same benchmark live under the same
+   `(organelle, train_set, model)` directory.
+5. Eval using Hydra is an implementation detail. It must not create a second
+   top-level config universe.
+6. Only path-free eval schema ships inside
+   `src/dynacell/evaluation/_configs/`.
+7. Any config with HPC paths, internal checkpoints, or canonical benchmark
+   run bindings lives under `configs/benchmarks/virtual_staining/`.
+
+## Public vs Internal Split
+
+### In-package, path-free eval schema
+
+These files stay under
+`applications/dynacell/src/dynacell/evaluation/_configs/`:
+
+- `eval.yaml`
+- `precompute.yaml`
+- `predict_set/ipsc_confocal.yaml`
+- `feature_extractor/dinov3/lvd1689m.yaml`
+- `spectral_pcc/*.yaml`
+
+These files define schema, path-free defaults, or diagnostic-tool defaults that
+can ship to external users.
+
+### Internal benchmark instances
+
+These files live under
+`applications/dynacell/configs/benchmarks/virtual_staining/`:
+
+- train leaves
+- predict leaves
+- eval leaves
+- eval targets with GT paths and channel bindings
+- internal DynaCLR checkpoint config
+- launcher metadata
+- benchmark output roots and save dirs
+
+These files are for repo users on our infrastructure. They are not part of the
+public package contract.

-## Key Rule
+## Ownership by Subtree
 
-- `configs/examples/` stays generic and public
-- `configs/benchmarks/virtual_staining/...` becomes the real benchmark layer
-- archived SEC61B configs in `dynacell-paper` remain historical reference only
+### `shared/model/`
 
-## Experiment Phase Mapping
+Owns internal benchmark building blocks used by Lightning train and predict
+leaves:
 
-The directory layout is meant to scale without changing shape between phases.
-Only the populated leaves change.
+- `train_sets/`: imaging modality and training data defaults
+- `predict_sets/`: imaging modality and prediction-domain defaults
+- `targets/`: target-channel choices, train data paths, normalizations, and
+  target-specific augmentations
+- `model_overlays/`: model-family defaults
+- `launcher_profiles/`: launcher mode, hardware, and runtime policy
 
-### Phase 1
+### `shared/eval/`
 
-Phase 1 fills the `train/er/...` subtree for all model families and both train
-sets:
+Owns internal benchmark building blocks used only by eval:
 
-- `train/er/ipsc_confocal/fnet3d.yml`
-- `train/er/ipsc_confocal/unext2_scratch.yml`
-- `train/er/ipsc_confocal/unext2_fcmae.yml`
-- `train/er/ipsc_confocal/unetvit3d.yml`
-- `train/er/ipsc_confocal/celldiff.yml`
-- the same five files under `train/er/ipsc_confocal_plus_mantis/`
+- `target/`: GT paths, segmentation paths, GT and prediction channel names
+- `feature_extractor/dynaclr/`: internal DynaCLR checkpoint and encoder config
 
-This is the broad comparison phase used to narrow model choice.
+### `<org>/<train_set>/<model>/`
 
-### Phase 2
+Owns canonical runnable leaves for one benchmark cell:
 
-Phase 2 reuses the same schema and shared-axis files, but fills only the
-`mito`, `nucleus`, and `membrane` subtrees, and only for the two shortlisted
-model families:
+- `train.yml`
+- `predict/<predict_set>.yml`
+- `eval/<predict_set>.yml`
 
-- `selected_deterministic`
-- `celldiff`
+That directory is the canonical place to inspect one benchmark configuration.
 
-That produces these leaf patterns:
+## Leaf Addressing
 
-- `train/mito/ipsc_confocal/selected_deterministic.yml`
-- `train/mito/ipsc_confocal/celldiff.yml`
-- `train/mito/ipsc_confocal_plus_mantis/selected_deterministic.yml`
-- `train/mito/ipsc_confocal_plus_mantis/celldiff.yml`
-- the same four-file pattern for `nucleus/`
-- the same four-file pattern for `membrane/`
+### Train
 
-This is intentionally repetitive. That repetition is a feature of the tree, not
-a design bug: it keeps every runnable benchmark job addressable by target,
-train set, and model family without introducing a second naming system.
+Path:
 
-### Scalability Constraint
-
-The shared-axis directories are what keep the repeated leaf structure from
-turning into a maintenance problem:
+```text
+configs/benchmarks/virtual_staining/<org>/<train_set>/<model>/train.yml
+```
 
-- `shared/train_sets/` owns data-source membership and base data paths
-- `shared/targets/` owns organelle-specific target-channel choices
-- `shared/model_overlays/` owns model-family defaults
-- `shared/launcher_profiles/` owns reusable hardware / mode / runtime policy
-- `shared/predict_sets/` owns prediction-domain inputs
+Example:
 
-New organelles or train sets should usually add one shared-axis file plus a new
-leaf subtree, not a new config convention.
+```text
+applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/train.yml
+```
 
-## Launcher Profile Schema
+Invocation:
 
-Launcher metadata should be composable too, not stored in one flat profile
-registry.
+```bash
+uv run dynacell fit -c applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/train.yml
+```
 
-The reusable axes are:
+### Predict
 
-- mode
-  - `fit`
-  - `predict`
-- hardware class
-  - `a6000_single`
-  - `h100x4`
-  - `h200_single`
-- runtime behavior
-  - `ddp`
-  - `single_gpu`
-  - `resume`
+Path:
 
-Use separate launcher-profile files under:
+```text
+configs/benchmarks/virtual_staining/<org>/<train_set>/<model>/predict/<predict_set>.yml
+```
 
-`applications/dynacell/configs/benchmarks/virtual_staining/shared/launcher_profiles/`
+Example:
 
-### Mode Profile
+```text
+applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/predict/ipsc_confocal.yml
+```
 
-`mode_fit.yml`
+Invocation:
 
-```yaml
-launcher:
-  mode: fit
+```bash
+uv run dynacell predict -c applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/predict/ipsc_confocal.yml
 ```
 
-### Hardware Profile
+### Eval
 
-`hardware_h100x4.yml`
+Path:
 
-```yaml
-launcher:
-  sbatch:
-    partition: gpu
-    nodes: 1
-    ntasks_per_node: 4
-    gpus: 4
-    cpus_per_task: 12
-    mem_per_cpu: "20G"
-    time: "48:00:00"
-    constraint: "a100_80|h100|h200"
+```text
+configs/benchmarks/virtual_staining/<org>/<train_set>/<model>/eval/<predict_set>.yml
 ```
 
-### Runtime Profile
+Example:
 
-`runtime_ddp.yml`
+```text
+applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/eval/ipsc_confocal.yml
+```
 
-```yaml
-launcher:
-  runtime:
-    use_srun: true
-    cleanup_tmp: true
-  env:
-    PYTHONUNBUFFERED: "1"
-    PYTHONFAULTHANDLER: "1"
-    NCCL_DEBUG: "INFO"
+Hydra selector:
+
+```text
+leaf=<org>/<train_set>/<model>/eval/<predict_set>
 ```
 
-### Example Single-GPU Profile
+Invocation:
 
-`hardware_h200_single.yml`
+```bash
+uv run dynacell evaluate leaf=er/ipsc_confocal/celldiff/eval/ipsc_confocal
+```
+
+The eval selector is named `leaf`, not `benchmark`. The benchmark already has a
+natural filesystem location; the selector should point at that leaf directly.
+
+## Composition Rules
+
+### Train leaf
+
+Train leaves continue to compose through the existing `viscy_utils.compose`
+mechanism.
+
+Canonical shape:

-Behavior:
+### Eval leaves
 
-1. Accept one config path.
-2. Compose it using the same base-resolution logic VisCy already uses.
-3. Read the resolved `launcher:` block after composition.
-4. Strip `launcher:` from the resolved config.
-5. Write:
-   - resolved runtime config to:
-     - `<run_root>/resolved/<mode>.resolved.yml`
-   - rendered SLURM script to:
-     - `<run_root>/slurm/<timestamp>_<job_name>.sbatch`
-6. Submit with `sbatch`, unless `--dry-run`.

+## Verification
+
+### Train compose
 
 ```bash
-uv run python applications/dynacell/tools/submit_benchmark_job.py \
-  applications/dynacell/configs/benchmarks/virtual_staining/train/er/ipsc_confocal/celldiff.yml
+uv run dynacell fit -c applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/train.yml --print_config
 ```
 
-Optional flags:
+### Predict compose
 
 ```bash
---dry-run
---print-script
---print-resolved-config
---override trainer.max_epochs=10
+uv run dynacell predict -c applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/predict/ipsc_confocal.yml --print_config
 ```
 
-## Important Rule
+### Eval compose
 
-`launcher:` is for the submit tool, not for direct `dynacell fit`.
-
-So:
+```bash
+uv run dynacell evaluate -c job leaf=er/ipsc_confocal/celldiff/eval/ipsc_confocal
+```
 
-- direct `dynacell fit -c <leaf.yml>` is not the primary entrypoint
-- primary entrypoint is:
-  - `submit_benchmark_job.py <leaf.yml>`
-- the submit tool produces the stripped resolved config and then runs
-  `dynacell fit -c <resolved.yml>`
+### Eval smoke
 
-This avoids any risk that Lightning/Hydra rejects unknown top-level keys.
+```bash
+uv run dynacell evaluate \
+  leaf=er/ipsc_confocal/celldiff/eval/ipsc_confocal \
+  limit_positions=1 compute_feature_metrics=false \
+  save.save_dir=/tmp/eval_leaf_smoke_$(date +%s)
+```
 
-## Implementation Sequence
+### Targeted tests
 
-### Phase 1 Files To Create
+```bash
+uv run pytest \
+  applications/dynacell/tests/test_benchmark_config_composition.py \
+  applications/dynacell/tests/test_cli_routing.py \
+  applications/dynacell/tests/test_submit_benchmark_job.py -q
+```
 
-Create the shared-axis files first, then create the ER leaves:

-That is enough to cover the current Phase 1 matrix.
+## Non-Goals
 
-### Phase 2 Extension Files
+- Do not change public `recipes/` or `examples/` layout here.
+- Do not ship internal HPC benchmark groups in the wheel.
+- Do not keep `configs/evaluation/` as a second internal root.
+- Do not preserve the old `benchmark=` eval selector only for compatibility.
 
-After Phase 1 results select the deterministic shortlist winner, add the Phase
-2 leaves by reusing the same shared files and changing only:
+## Rationale
 
-- target subtree: `mito/`, `nucleus/`, `membrane/`
-- model leaf names: `selected_deterministic.yml`, `celldiff.yml`
-- phase metadata in `benchmark.phase`
+This schema makes one benchmark inspectable in one place.
 
-The required file patterns are:
+For any organelle, train set, and model, the user can open one directory and
+see:

-```
+- how the model is trained
+- how it predicts on the test set
+- how those predictions are evaluated
 
-Only one extra naming decision is needed at that point: replace
-`selected_deterministic.yml` with the actual winning model family
-(`fnet3d.yml`, `unext2_scratch.yml`, `unext2_fcmae.yml`, or `unetvit3d.yml`).
+That is the correct filesystem model for dynacell benchmarking.

Subject: [PATCH 137/311] refactor(configs): unify benchmark tree with
 train+predict+eval per cell
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Restructure applications/dynacell/configs/benchmarks/virtual_staining/
so train, predict, and eval leaves for the same benchmark cell live
under one directory `<org>/<train_set>/<model>/`, with shared building
blocks split by consumer:

- `shared/model/` — train/predict building blocks (train_sets,
  predict_sets, targets, model_overlays, launcher_profiles)
- `shared/eval/` — HPC-bound Hydra eval groups (target, feature_extractor/dynaclr)
- `<org>/<train_set>/<model>/{train.yml, predict/<predset>.yml, eval/<predset>.yaml}`

Fold `configs/evaluation/` into the benchmark tree and delete the
sibling root. The eval selector renames from `benchmark=<path>` to
`leaf=<path>` to reflect the new filesystem model; leaves are addressed
through a committed symlink tree at `virtual_staining/leaf/` because
Hydra's group resolution requires a physical `leaf/` prefix. Eval
leaves keep `.yaml` (Hydra only discovers `.yaml` for groups); train
and predict leaves stay `.yml`.

`dynacell.__main__` now injects two `hydra.searchpath` roots — the
benchmark tree (for `leaf/`) and `shared/eval/` (for `target/` and
`feature_extractor/dynaclr/`). The `_EXTERNAL_CONFIGS_SUBPATH` constant
becomes `_EXTERNAL_SEARCHPATHS`, and the helper is renamed to
`_external_configs_dirs` (plural, returning a list).

Also fixes a pre-existing bug: the three unetvit3d train leaves under
mito/nucleus/membrane referenced a non-existent `runtime_single_gpu.yml`
launcher profile; they now use `runtime_shared.yml`. Model-overlay
`base:` entries targeting `recipes/` gain an extra `..` segment to
account for the new `shared/model/` depth.

Tests:
- test_benchmark_config_composition.py: path literals, three new
  (unetvit3d × {mito,nucleus,membrane}) pairs, new
  test_eval_leaf_symlink_resolves parametrised over all 8 eval leaves.
- test_cli_routing.py: three `_external_configs_dir` patches renamed
  (plural) and argv selector strings updated to `leaf=`.
- test_submit_benchmark_job.py: parametrised leaf paths.

Docs: virtual_staining/README.md (full rewrite to match new tree),
evaluation/README.md (groups table, external-users section, benchmark
eval leaves section), UNEXT2_VS_FCMAE_CLASSES.md (stale path), dynacell/
README.md (sbatch example path), BENCHMARK_CONFIG_SCHEMA.md (Hydra
search-path contract note about the `leaf/` symlink adapter).

-**Eval leaves live in a sibling tree.** Evaluation uses Hydra (not LightningCLI),
-so eval configs compose through a different mechanism. Canonical eval benchmark
-leaves live at
-`applications/dynacell/configs/evaluation/benchmark/<org>/<train_set>/<model>/<predict_set>.yaml`
-(alongside this tree, not under `virtual_staining/`). The HPC-bound target groups
-and the DynaCLR checkpoint config share that directory. A `hydra.searchpath`
-injection in `dynacell.__main__` makes them discoverable when running from a repo
-checkout; schema-only configs ship inside the dynacell package (wheel installs see
-only those). Invoke via `dynacell evaluate benchmark=<path>`; see
-`applications/dynacell/src/dynacell/evaluation/README.md` for details.
+Train/predict leaves use LightningCLI (`.yml`). Eval leaves use Hydra and
+keep `.yaml` because Hydra's group resolution only discovers `.yaml` files.
+The `leaf/` symlink tree aliases each eval leaf so Hydra's `leaf=<path>`
+selector can discover them at `<searchpath>/leaf/<path>.yaml`.
+
+Eval runtime uses two search paths injected by `dynacell.__main__`:
+`virtual_staining/` (for the `leaf/` tree) and
+`virtual_staining/shared/eval/` (for the `target/` and
+`feature_extractor/dynaclr/` groups). Schema-only eval configs ship
+inside the dynacell package; wheel installs without the repo don't see
+the HPC-bound groups and external users provide their own via
+`--config-dir`. See `applications/dynacell/src/dynacell/evaluation/README.md`.

From 29cd6980ad34b29c9eb17725c83cf9fb9ccdc1ff Mon Sep 17 00:00:00 2001
From: Alexandr Kalinin <alxndrkalinin@users.noreply.github.com>
Date: Mon, 20 Apr 2026 19:13:24 -0700
Subject: [PATCH 138/311] fix(configs): update train/predict leaf base: paths
 after shared/model/ move
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The preceding refactor commit renamed train and predict leaves to
<org>/<train_set>/<model>/{train.yml, predict/<predset>.yml} but the
content updates that prepend the shared/model/ segment to every base:
line were unstaged when that commit landed. This catches the 25 train
and predict leaves up with the new shared/model/ layout, and tightens a
prose comment in fnet3d_paper_fit.yml that still referenced the
pre-refactor shared/targets/ path.

Without this fix a fresh checkout of the reorg commit has train and
predict leaves pointing at shared/train_sets/, shared/targets/, etc. —
paths that no longer exist — so `load_composed_config` would raise
FileNotFoundError on every leaf.

Subject: [PATCH 139/311] refactor(__main__,tests): apply simplify review
 cleanup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Trim the WHAT-narration from docstrings and comments in
dynacell.__main__: drop the redundant "two roots are injected"
enumeration (the tuple is self-describing), fix the "repo root"
claim in _external_configs_dirs (the walk stops at the app's
pyproject.toml, not the workspace root), and drop the
"joined with commas" line from _inject_external_configs' docstring.
Bind ``p = parent / sub`` via walrus inside the existence filter
so the path is computed once instead of twice per subpath.

In the composition tests, delete the ``EVAL_LEAVES = PREDICT_LEAVES``
alias (the aliased list was the same object, causing silent coupling)
and drive the symlink-integrity test off ``PREDICT_LEAVES`` directly.
Drop the ``@package _global_`` header assertion from the symlink test
— that check belongs to composition, not to symlink integrity. Add a
``REPO_ROOT`` sanity assert so drift of the ``parents[3]`` magic
count fails loudly.

Tighten ``TestInjectExternalConfigs`` class docstring to a single
line.

Subject: [PATCH 140/311] docs(eval): refresh README for post-reorg config
 layout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the "in-package / repo checkout" shorthand in the config-groups
table with concrete source paths, so readers see exactly where each
group lives after the reorg: shared/eval/ for HPC-bound groups, leaf/
for the eval-leaf symlink tree, _configs/ for packaged schema.

Tighten the "Running an evaluation" intro so it no longer implies all
groups live under _configs/, and spell out the two hydra.searchpath
roots dynacell.__main__ injects.

Add a footgun entry for external users about Hydra's .yaml-only group
resolution — saving a group as .yml makes the selector silently fail
with MissingConfigException.

 ### Benchmark eval leaves

Subject: [PATCH 141/311] refactor(configs): move shared/ + leaf/ under hidden
 _internal/ root
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Keep the top level of virtual_staining/ biology-only: `er/`, `membrane/`,
`mito/`, `nucleus/` plus README.md. Everything else — shared building
blocks and the leaf/ Hydra symlink adapter — now lives under a single
_internal/ directory whose leading underscore signals "implementation
detail; don't browse here for science."

Layout is now:

    virtual_staining/
      <org>/<train_set>/<model>/{train.yml, predict/, eval/}
      _internal/
        shared/
          model/         # train/predict building blocks
          eval/          # target/, feature_extractor/dynaclr/
        leaf/            # symlink tree aliasing canonical eval leaves

dynacell.__main__ injects two hydra.searchpath roots under _internal/
(the tree root for leaf/, and shared/eval/ for target + dynaclr) —
same cardinality as before, just under the hidden support tree.

Train/predict leaves get `_internal/` prepended to every base: path.
Model overlays gain one more `../` to reach configs/recipes/ (now 6
segments deep instead of 5). The 8 leaf/ symlinks are recreated with
6 relative-dot segments (was 5 at virtual_staining/leaf/, now 6 at
virtual_staining/_internal/leaf/).

Docs refreshed across BENCHMARK_CONFIG_SCHEMA.md, virtual_staining/
README.md, and evaluation/README.md: every layout tree, base: example,
group-source column, and search-path reference points at _internal/.

Subject: [PATCH 142/311] fix(engine): honor predict_overlap and multi-channel
 sliding windows

Two related bugs in predict-path tiling:

P1. DynacellFlowMatching.predict_step routed predict_method='sliding_window'
to CELLDiff3DVS.generate_sliding_window(), which is the non-overlapping
tiler and does not consume predict_overlap. Any config that set both
predict_method='sliding_window' and predict_overlap=[...] silently got
non-overlapping tiles, producing different predictions than the user
expected. Now raise ValueError when sliding_window is combined with a
non-zero overlap, pointing users to predict_method='iterative' (the
overlap-anchored velocity tiler) instead. Also refresh the docstring
to spell out which methods consume predict_overlap. Fix the membrane
predict leaf to match its peers (er, mito): predict_method=iterative.
Example config at configs/examples/celldiff/predict.yml gets the same
fix plus an inline comment clarifying which methods overlap.

P2. DynacellUNet.predict_sliding_window allocated both accumulator
buffers (prediction_sum, prediction_count) with zeros_like(source),
so their channel dimension was always in_channels. For models whose
out_channels != in_channels (common: 1 phase in -> 2 target out), the
first `prediction_sum[slicer] += patch_out` raised a broadcast error.
Allocate the accumulators lazily from the first patch output so they
take the model's actual out_channels and dtype.

Regression tests added for both paths:
- sliding_window + non-zero overlap must raise ValueError
- predict_sliding_window returns the correct shape when out_channels=2

Subject: [PATCH 143/311] fix(__main__): keep hydra.searchpath adjacent to
 positional overrides

The earlier "always append" strategy broke argparse when users placed
diagnostic flags (-c job, --info, --help, ...) after positional
overrides:

    $ dynacell evaluate leaf=er/... -c job
    dynacell: error: unrecognized arguments: hydra.searchpath=[file://...]

Hydra's argparse declares ``overrides`` as a single positional with
nargs="*". Once that nargs run is interrupted by a flag, any later
positional is reported unrecognized. Appending the injected token at
the end scatters a positional across the flag in the override-first
layout; prepending scatters it across the flag in the flag-first layout.

Fix: insert the token adjacent to an existing positional override when
one is present, so positionals stay contiguous whichever side the
flags sit on. Fall back to append when the user passed no positional
overrides (e.g. bare --help).

Three regression tests cover the three layouts: flag-leading,
flag-trailing, and no-positional. The former "appends always" test is
replaced by the layout-specific pair.

-# Dynacell Benchmark Config Schema
-
-This document defines the target benchmark-config layout for
-`applications/dynacell/configs/benchmarks/virtual_staining/`.
-
-It replaces the older split where:
-
-- train and predict leaves lived under `configs/benchmarks/virtual_staining/`
-- eval leaves and eval target groups lived in a separate top-level
-  `configs/evaluation/` tree
-
-That split is not worth keeping. The benchmark unit is simple:
-
-- choose an organelle
-- train one or more models
-- run prediction on a test set
-- evaluate the resulting prediction store
-
-The filesystem layout should follow that workflow directly.
-
-## Goals
-
-- keep one canonical internal tree for the full virtual-staining workflow
-- make train, predict, and eval leaves sit next to each other
-- keep reusable public schema in the installed `dynacell` package
-- keep HPC-specific benchmark instances out of `src/`
-- make every canonical benchmark run addressable by
-  `(organelle, train_set, model, stage, predict_set)`
-
-## Design Rules
-
-1. `configs/recipes/` stays public and reusable.
-2. `configs/examples/` stays small and generic.
-3. `configs/benchmarks/virtual_staining/` is the canonical internal benchmark tree.
-4. Train, predict, and eval leaves for the same benchmark live under the same
-   `(organelle, train_set, model)` directory.
-5. Eval using Hydra is an implementation detail. It must not create a second
-   top-level config universe.
-6. Only path-free eval schema ships inside
-   `src/dynacell/evaluation/_configs/`.
-7. Any config with HPC paths, internal checkpoints, or canonical benchmark
-   run bindings lives under `configs/benchmarks/virtual_staining/`.
-
-## Public vs Internal Split
-
-### In-package, path-free eval schema
-
-These files stay under
-`applications/dynacell/src/dynacell/evaluation/_configs/`:
-
-- `eval.yaml`
-- `precompute.yaml`
-- `predict_set/ipsc_confocal.yaml`
-- `feature_extractor/dinov3/lvd1689m.yaml`
-- `spectral_pcc/*.yaml`
-
-These files define schema, path-free defaults, or diagnostic-tool defaults that
-can ship to external users.
-
-### Internal benchmark instances
-
-These files live under
-`applications/dynacell/configs/benchmarks/virtual_staining/`:
-
-- train leaves
-- predict leaves
-- eval leaves
-- eval targets with GT paths and channel bindings
-- internal DynaCLR checkpoint config
-- launcher metadata
-- benchmark output roots and save dirs
-
-These files are for repo users on our infrastructure. They are not part of the
-public package contract.

-## Ownership by Subtree
-
-### `_internal/`
-
-Hidden support tree whose leading underscore signals "implementation
-detail." Keeps the top level of `virtual_staining/` biology-only. Holds
-every non-canonical file: the `shared/` building blocks and the `leaf/`
-symlink adapter Hydra needs.
-
-### `_internal/shared/model/`
-
-Owns internal benchmark building blocks used by Lightning train and predict
-leaves:
-
-- `train_sets/`: imaging modality and training data defaults
-- `predict_sets/`: imaging modality and prediction-domain defaults
-- `targets/`: target-channel choices, train data paths, normalizations, and
-  target-specific augmentations
-- `model_overlays/`: model-family defaults
-- `launcher_profiles/`: launcher mode, hardware, and runtime policy
-
-### `_internal/shared/eval/`
-
-Owns internal benchmark building blocks used only by eval:
-
-- `target/`: GT paths, segmentation paths, GT and prediction channel names
-- `feature_extractor/dynaclr/`: internal DynaCLR checkpoint and encoder config
-
-### `_internal/leaf/`
-
-Symlink tree aliasing the canonical eval leaves so Hydra's `leaf=<path>`
-selector can discover them (Hydra group resolution requires a physical
-`leaf/` directory in the searchpath). Each symlink points back at
-`<org>/<train_set>/<model>/eval/<predset>.yaml` — the canonical location
-where train + predict + eval for one benchmark cell sit side by side.
-
-### `<org>/<train_set>/<model>/`
-
-Owns canonical runnable leaves for one benchmark cell:
-
-- `train.yml`
-- `predict/<predict_set>.yml`
-- `eval/<predict_set>.yml`
-
-That directory is the canonical place to inspect one benchmark configuration.
-
-## Leaf Addressing
-
-### Train
-
-Path:
-
-```text
-configs/benchmarks/virtual_staining/<org>/<train_set>/<model>/train.yml
-```
-
-Example:
-
-```text
-applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/train.yml
-```
-
-Invocation:
-
-```bash
-uv run dynacell fit -c applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/train.yml
-```
-
-### Predict
-
-Path:
-
-```text
-configs/benchmarks/virtual_staining/<org>/<train_set>/<model>/predict/<predict_set>.yml
-```
-
-Example:
-
-```text
-applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/predict/ipsc_confocal.yml
-```
-
-Invocation:
-
-```bash
-uv run dynacell predict -c applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/predict/ipsc_confocal.yml
-```
-
-### Eval
-
-Path:
-
-```text
-configs/benchmarks/virtual_staining/<org>/<train_set>/<model>/eval/<predict_set>.yaml
-```
-
-Example:
-
-```text
-applications/dynacell/configs/benchmarks/virtual_staining/er/ipsc_confocal/celldiff/eval/ipsc_confocal.yaml
-```
-
-Eval leaves keep the `.yaml` extension — Hydra's group resolver only
-discovers `.yaml` files, so renaming to `.yml` makes `leaf=<path>`,
-`target=<name>`, and `feature_extractor/dynaclr=<name>` all fail with
-`MissingConfigException`. Lightning-side train/predict leaves stay
-`.yml` because `viscy_utils.compose` is extension-agnostic.
-
-Hydra selector:
-
-```text
-leaf=<org>/<train_set>/<model>/eval/<predict_set>
-```
-
-Invocation:
-
-```bash
-uv run dynacell evaluate leaf=er/ipsc_confocal/celldiff/eval/ipsc_confocal
-```
-
-The eval selector is named `leaf`, not `benchmark`. The benchmark already has a
-natural filesystem location; the selector should point at that leaf directly.
-
-## Composition Rules
-
-### Train leaf
-
-Train leaves continue to compose through the existing `viscy_utils.compose`
-mechanism.
-
-Canonical shape:
-
-```yaml
-base:
-  - ../../../_internal/shared/model/train_sets/<train_set>.yml
-  - ../../../_internal/shared/model/targets/<target>.yml
-  - ../../../_internal/shared/model/model_overlays/<model>_fit.yml
-  - ../../../_internal/shared/model/launcher_profiles/mode_fit.yml
-  - ../../../_internal/shared/model/launcher_profiles/hardware_<hw>.yml
-  - ../../../_internal/shared/model/launcher_profiles/runtime_shared.yml
-```
-
-### Predict leaf
-
-Canonical shape:
-
-```yaml
-base:
-  - ../../../../_internal/shared/model/predict_sets/<predict_set>.yml
-  - ../../../../_internal/shared/model/targets/<target>.yml
-  - ../../../../_internal/shared/model/model_overlays/<model>_predict.yml
-  - ../../../../_internal/shared/model/launcher_profiles/mode_predict.yml
-  - ../../../../_internal/shared/model/launcher_profiles/hardware_<hw>.yml
-  - ../../../../_internal/shared/model/launcher_profiles/runtime_shared.yml
-```
-
-### Eval leaf
-
-Eval leaves compose through Hydra, not `viscy_utils.compose`.
-
-Canonical shape:
-
-```yaml
-# @package _global_
-defaults:
-  - override /target: <target>
-  - override /predict_set: <predict_set>
-  - override /feature_extractor/dinov3: lvd1689m
-  - override /feature_extractor/dynaclr: default
-
-io:
-  pred_path: /hpc/.../predictions.zarr
-  gt_cache_dir: /hpc/.../cache
-
-compute_feature_metrics: true
-
-save:
-  save_dir: /hpc/.../eval_results
-```
-
-Hydra resolves:
-
-- `target` from `_internal/shared/eval/target/`
-- `feature_extractor/dynaclr` from `_internal/shared/eval/feature_extractor/dynaclr/`
-- `predict_set` from the in-package public group
-- `leaf` from `_internal/leaf/` (symlinks back to the canonical eval leaves
-  at `<org>/<train_set>/<model>/eval/<predict_set>.yaml`)
-
-## Hydra Search-Path Contract
-
-The eval runtime uses:
-
-- packaged schema under `src/dynacell/evaluation/_configs/`
-- repo-local benchmark groups under:
-  - `configs/benchmarks/virtual_staining/_internal/` (holds the `leaf/`
-    symlink tree)
-  - `configs/benchmarks/virtual_staining/_internal/shared/eval/` (holds
-    `target/` and `feature_extractor/dynaclr/`)
-
-`dynacell.__main__` injects those two roots through
-`hydra.searchpath=[file://...]` when running from a repo checkout.
-
-Hydra group resolution requires a physical `leaf/` directory in the
-searchpath so that `leaf=<org>/<train_set>/<model>/eval/<predset>`
-resolves to `<searchpath>/leaf/<path>.yaml`. The canonical eval leaves
-live next to their train/predict siblings at
-`<org>/<train_set>/<model>/eval/<predset>.yaml`; a parallel symlink tree
-under `_internal/leaf/` mirrors the benchmark structure and points each
-symlink back at the canonical file. Keeping the whole support tree under
-a single leading-underscore dir (`_internal/`) means the top level of
-`virtual_staining/` shows only biology + README — no exposed service
-dirs — while the "one directory per benchmark" goal for
-`<org>/<train_set>/<model>/` stays intact.
-
-Wheel installs do not see those internal benchmark groups. External users get:
-
-- `eval.yaml`
-- `precompute.yaml`
-- path-free groups such as `predict_set/ipsc_confocal`
-- the ability to provide their own groups via `--config-dir`
-
-## Exact Migration From Current Tree
-
-### Shared model files
-
-Move:
-
-- `shared/train_sets/*` -> `_internal/shared/model/train_sets/*`
-- `shared/predict_sets/*` -> `_internal/shared/model/predict_sets/*`

-  `er/ipsc_confocal/unetvit3d/eval/ipsc_confocal.yaml`
-
-Apply the same pattern for `membrane`, `mito`, and `nucleus`.
-
-### Cleanup
-
-After the move:

-  leaf=er/ipsc_confocal/celldiff/eval/ipsc_confocal \
-  limit_positions=1 compute_feature_metrics=false \
-  save.save_dir=/tmp/eval_leaf_smoke_$(date +%s)
-```
-
-### Targeted tests
-
-```bash
-uv run pytest \
-  applications/dynacell/tests/test_benchmark_config_composition.py \
-  applications/dynacell/tests/test_cli_routing.py \
-  applications/dynacell/tests/test_submit_benchmark_job.py -q
-```
-
-### Full dynacell suite
-
-```bash
-uv run pytest applications/dynacell -q
-```
-
-## Non-Goals
-
-- Do not change public `recipes/` or `examples/` layout here.
-- Do not ship internal HPC benchmark groups in the wheel.
-- Do not keep `configs/evaluation/` as a second internal root.
-- Do not preserve the old `benchmark=` eval selector only for compatibility.
-
-## Rationale
-
-This schema makes one benchmark inspectable in one place.
-
-For any organelle, train set, and model, the user can open one directory and
-see:
-
-- how the model is trained
-- how it predicts on the test set
-- how those predictions are evaluated
-
-That is the correct filesystem model for dynacell benchmarking.

Subject: [PATCH 146/311] fix(dynacell): emit --ntasks-per-node for
 SLURM/Lightning compat
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Lightning's SLURMEnvironment rejects --ntasks at runtime
(slurm.py:_validate_srun_variables) and demands --ntasks-per-node.
Yesterday's fix emitted the wrong directive; all four FCMAE jobs
failed within 50 s on the cluster. Switch the sbatch generator,
hardware profiles, pre-submit validator, and invariant test to use
ntasks_per_node throughout. The enforced invariant is now
devices == ntasks_per_node and gpus == nodes × devices.

Subject: [PATCH 147/311] feat(eval): share DINOv3 + other HF artifacts across
 team via HF_HOME
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Gated HF repos (DINOv3) need per-user access grants, but the downloaded
weights are identical. Before this change every team member who ran
`dynacell evaluate compute_feature_metrics=true` re-downloaded ~2 GB
of DINOv3 weights into their own `~/.cache/huggingface/`. Even ignoring
the network cost, only one team member has HF gate access right now —
every other member's runs 403 at model fetch.

Fix: point HF_HOME at a team-shared project-storage dir. First user
with gated access downloads once; everyone else reads the shared copy.

Two layers so the behavior is automatic regardless of invocation:

1. `dynacell.__main__._maybe_set_shared_hf_cache()` runs before Hydra
   subcommands (evaluate, precompute-gt, report). It defaults HF_HOME
   to
   `/hpc/projects/comp.micro/virtual_staining/models/dynacell/evaluation/hf_cache/`
   when three conditions hold: the user hasn't set HF_HOME themselves,
   we're on a repo checkout (same signal as external configs), and the
   shared dir exists on this machine. Wheel installs and non-HPC
   machines fall through to the normal ~/.cache/huggingface default.

2. `runtime_shared.yml` also sets HF_HOME for sbatch-rendered fit /
   predict jobs. Those jobs don't currently load HF models, but having
   the env var declared in the launcher profile future-proofs any
   later workflow that does and keeps the team convention visible in
   config.

Four regression tests cover the auto-setter: user-set wins, wheel
install skips, missing shared dir skips, repo checkout + existing dir
sets. README documents the mechanism and first-time download contract.

Subject: [PATCH 148/311] feat(eval): pin canonical feature-extractor and
 gt_cache_dir defaults
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three defaults were required on every eval / precompute-gt invocation
even though they are effectively fixed for our benchmark set:

  feature_extractor/dinov3=lvd1689m       (only DINOv3 we evaluate with)
  feature_extractor/dynaclr=default       (team DynaCLR checkpoint)
  io.gt_cache_dir=/hpc/.../eval_cache/<TARGET>   (one dir per target)

Hoist them so the minimal command

  dynacell precompute-gt target=er_sec61b predict_set=ipsc_confocal

composes everything needed for all four cache families, and

  dynacell evaluate leaf=<...>

carries the same defaults without the redundant override directives.

- eval.yaml defaults list switches
    optional feature_extractor/dinov3: null   -> lvd1689m
    optional feature_extractor/dynaclr: null  -> default
  The `optional` keyword means wheel installs that don't ship
  dynaclr=default (it lives in the repo's shared/eval/ tree) silently
  skip the default — wheel users supply their own via --config-dir.
- Each target YAML now carries io.gt_cache_dir for its target's cache
  path (SEC61B, TOMM20, nucleus, membrane).
- The 8 canonical eval leaves drop the redundant
    override /feature_extractor/dinov3: lvd1689m
    override /feature_extractor/dynaclr: default
  and the per-leaf io.gt_cache_dir — all now inherited.
- README updated: "Enable feature metrics" and "Priming the cache"
  examples show the one-line minimal forms.

To swap variants at call-time nothing changes:
  dynacell evaluate ... feature_extractor/dinov3=<other_variant>
  dynacell evaluate ... feature_extractor.dynaclr.checkpoint=/other.ckpt
  dynacell evaluate ... feature_extractor/dinov3=null   # disable

Subject: [PATCH 149/311] refactor(__main__,tests): apply simplify review
 cleanup

Three issues from /simplify agents:

- Hardcoded HPC path in _SHARED_HF_CACHE makes the module CZ Biohub-
  specific; other sites couldn't override without editing source. Read
  DYNACELL_SHARED_HF_CACHE at module load and fall back to the CZ
  Biohub default only when the env var is absent. Extension story is
  now: set DYNACELL_SHARED_HF_CACHE in your shell / sbatch env block
  and the rest of the mechanism just works.
- Docstring on _maybe_set_shared_hf_cache named the sibling helper
  _external_configs_dirs; rephrase in semantic terms ("external Hydra
  searchpaths resolve") so the docstring doesn't rot if the detection
  mechanism ever changes.
- Four test methods in TestMaybeSetSharedHfCache imported `os` inline
  instead of at module top (violates CLAUDE.md). Plus a redundant
  monkeypatch.delenv() cleanup at the end of the last test that
  pytest's monkeypatch fixture already handles on teardown. Lift
  `import os` to module top, drop the inline imports, drop the
  redundant cleanup.

Skipped /simplify nitpicks:
- functools.cache on _external_configs_dirs (6-8 stat calls saved
  per CLI invocation; not worth the cognitive cost of a cache that
  has to coexist with tests that patch the function reference)
- Parametrize the 4 tests (4 is small enough to leave explicit)
- Inline comment on opaque group names (marginal signal)

Subject: [PATCH 150/311] fix(eval): shared HF cache uses HF_HUB_CACHE not
 HF_HOME
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Setting HF_HOME to the team-shared project-storage dir inadvertently
broke per-user gated-repo authentication: HF_HOME relocates the entire
HF directory tree including the auth token file. The first precompute
attempt with DINOv3 enabled came back 401 "Access to model ... is
restricted. You must have access to it and be authenticated to access
it" — not a missing grant (the user had been granted access, which
would have returned 403), but a missing token. HF was looking under
$HF_HOME/token, where no token file lives.

Switch to HF_HUB_CACHE, which only relocates the weights/datasets
cache and leaves auth state at its default ~/.cache/huggingface/token.
Each user's personal token now enforces gate ACLs on their own
account; the cache of downloaded weights is shared on project
storage as intended.

The _maybe_set_shared_hf_cache helper and its four tests flip from
HF_HOME → HF_HUB_CACHE. The runtime_shared.yml launcher env block
does the same. README gains a paragraph explaining *why* we chose
HF_HUB_CACHE over HF_HOME, and clarifies that subsequent reads from
the shared cache are plain disk reads that don't round-trip to HF and
so don't need a token at all.

Subject: [PATCH 151/311] fix(configs): halve FCMAE dataloader workers to stay
 under 512G cgroup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previous 4-GPU FCMAE runs OOM-killed before first training step. On
gpu-c-1 sstat showed MaxVMSize=103G/rank at startup — 4 ranks × 103G
≈ 412G of virtual memory, plus mmap_preload /dev/shm staging, pushed
past the 512G cgroup cap. num_workers=8 per rank meant 32 dataloader
workers inflating per-rank VM before the first step. Halving to 4
cuts startup VM roughly in half while keeping prefetch above the
single-worker bottleneck.

Subject: [PATCH 152/311] refactor(configs): group benchmark leaves by train
 set under <org>/<model>/
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Regroup the virtual_staining benchmark tree so a training experiment
lives in one directory. Paths go from <org>/<train_set>/<model>/ with
separate train/predict/eval subdirs to <org>/<model>/<train_set>/ with
flat predict__<predict_set>.yml and eval__<predict_set>.yaml filenames.

The old layout assumed each (org, model) cell had exactly one training
run. New research requirements — joint ipsc_confocal + a549_mantis
training, plus evaluating each trained model on both held-out splits —
make train_set an index within a cell rather than a hierarchy. Grouping
by train set puts a training run (train + its predicts + its evals)
in a single subdir so adding or removing an experiment is one `mkdir`
or one `rm -r`.

33 leaf moves (17 train + 8 predict + 8 eval), 8 _internal/leaf symlink
rewrites (5-up target instead of 6-up, new eval__<X>.yaml filename),
predict base: paths lose one ../ (depth 4 -> 3), tests + tool docstring
+ 4 READMEs track the new layout. New selectors: leaf=er/celldiff/
ipsc_confocal/eval__ipsc_confocal. No __main__.py code change — search
path roots (_internal/ and _internal/shared/eval/) are unaffected.

+Leaves are grouped by **train set** inside each `<org>/<model>/` cell so
+that a training experiment (train + the predict/eval variants fed by its
+checkpoint) lives in one directory. Adding a new training run — e.g. the
+planned `joint_ipsc_confocal_a549_mantis` mix — means creating one new
+subdir; deleting one is `rm -r`. Each train-set dir holds one `train.yml`
+plus one `predict__<predict_set>.yml` and `eval__<predict_set>.yaml` per
+held-out split the model is evaluated on.

Subject: [PATCH 153/311] fix(evaluation): independent min-max norm for
 metrics, fix cache context early return, fill eval defaults

- nrmse/psnr/ssim now normalize each image independently (min-max) instead of jointly
- init_cache_context early return (no gt_cache_dir) was missing dinov3/dynaclr fields
- eval.yaml: fill in default dinov3 model name and dynaclr encoder config

Subject: [PATCH 154/311] feat(dynacell): manifest-driven dataset_ref resolver
 for benchmark leaves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Stage 1 of the A549 expansion roadmap. Benchmark leaves now declare
`benchmark.dataset_ref: {dataset, target}` instead of hardcoding
`data_path`, `source_channel`, and `target_channel` per target. A
composition-time resolver reads a Pydantic DatasetManifest YAML from
roots configured via (in order) CLI roots → DYNACELL_MANIFEST_ROOTS env
var → entry points under `dynacell.manifest_roots`. The resolver is a
plain callable threaded through `viscy_utils.compose.load_composed_config`
as a keyword-only `resolver=` kwarg so viscy-utils stays generic.

Partial `dataset_ref` is a strict no-op: leaves that inherit only one
half (e.g. `{dataset: aics-hipsc}` from the shared ipsc_confocal
train_set) compose byte-identically until their target fragment is also
migrated. This makes Stage 2 (per-organelle migration) safe to roll out
incrementally.

Migrates the full ER-on-iPSC slice as a proof of end-to-end parity:
targets/er_sec61b.yml, train_sets/ipsc_confocal.yml,
predict_sets/ipsc_confocal.yml, and both ER predict leaves (celldiff,
unetvit3d). Non-ER leaves inherit partial refs and are untouched until
their targets migrate. Shared `source_channel: Phase3D` stays in the
ipsc_confocal fragments; the resolver tolerates matching values and
raises only on mismatch, which keeps non-ER leaves composing correctly
during the staged rollout.

The Lightning branch of dynacell's `main_cli` catches
NoManifestRootsError / ManifestNotFoundError / TargetNotFoundError and
prints the message to stderr with exit code 2 — no stack trace for user
misconfiguration.

Subject: [PATCH 155/311] docs(dynacell): roadmap + spec for dataset_ref
 resolver staged rollout

A549_EXPANSION_ROADMAP.md sequences the 6-stage rollout that moves the
benchmark tree from hardcoded per-target paths to manifest-driven
resolution, so iPSC confocal and a549 mantis datasets can coexist
without path duplication.

DATASET_REF_RESOLVER_SPEC.md is the authoritative spec for the Stage 1
resolver that just landed in 0aa7e1a. Both docs live in-tree so future
readers can reconstruct why the resolver exists and how the remaining
stages (per-target migration, eval-side resolution, eval target
migration, a549 manifest, a549 leaf expansion) should land.

+# A549 Expansion Roadmap
+
+## Context
+
+The current `virtual_staining/` tree is populated only for `ipsc_confocal`
+training and evaluation. Research requirements expand this to:
+
+- **Two training sets per (organelle, model) cell**: `ipsc_confocal` and
+  `joint_ipsc_confocal_a549_mantis`.
+- **Two held-out evaluation splits per trained model**: `ipsc_confocal`
+  and `a549_mantis`. Every trained model evaluates on both, regardless of
+  training source, so cross-dataset transfer is measurable.
+
+The post-reorg layout (`14f59f1`) already supports this — each
+`<org>/<model>/<train_set>/` dir is a training experiment with room for
+multiple `predict__<predict_set>.yml` and `eval__<predict_set>.yaml`
+leaves. The gap is the underlying **data-path plumbing**: every leaf
+today hardcodes `data_path`, `source_channel`, `target_channel` (for
+train/predict) or `gt_path`, `cell_segmentation_path`, `gt_cache_dir`
+(for eval). Naively expanding to a549 duplicates all of this across
+roughly 60 new leaves, which becomes technical debt the moment any path
+moves.
+
+`DATASET_REF_RESOLVER_SPEC.md` proposes exactly the right fix for the
+train/predict side: a manifest-driven resolver so leaves reference a
+dataset by name (`benchmark.dataset_ref: {dataset, target}`) and the
+composition layer splices in paths and channels from a Pydantic
+manifest. This roadmap sequences the resolver PR, its follow-ups, and
+the a549 expansion so each stage lands on top of a solid foundation.
+
+## How the two workstreams relate
+
+- **Question B from the a549 scoping discussion** (how to disentangle
+  organelle identity from dataset-specific paths in `target/` YAMLs) is
+  precisely what the resolver solves. The manifest owns the paths; the
+  Hydra `target/` group owns only channel names and organelle identity.
+- Duplicating a549-variant target YAMLs today (`er_sec61b_a549.yaml` and
+  friends) would write exactly the path duplication the resolver is
+  designed to eliminate. Don't do it.
+- The spec's non-goal #1 is eval-side resolution; the a549 eval
+  expansion needs that, so we either wait for the eval-side follow-up
+  or write eval leaves with hardcoded paths (debt). This roadmap waits.
+
+## Staged plan
+
+### Stage 1 — Resolver PR (per `DATASET_REF_RESOLVER_SPEC.md`)
+
+Scope exactly as the spec describes:
+
+- `packages/viscy-utils/src/viscy_utils/compose.py`: add optional
+  keyword-only `resolver: Callable[[dict], dict] | None` to
+  `load_composed_config`.
+- `applications/dynacell/src/dynacell/data/manifests.py`: add
+  `DatasetRef` Pydantic model.
+- `applications/dynacell/src/dynacell/data/resolver.py`: new module with
+  `ResolvedDataset`, `discover_manifest_roots`, `resolve_dataset_ref`,
+  three error classes.
+- `applications/dynacell/src/dynacell/_compose_hook.py`:
+  `_dynacell_ref_resolver` that reads `composed["benchmark"]["dataset_ref"]`,
+  infers mode, splices `data_path` / `source_channel` / `target_channel`.
+- Wire the hook in `dynacell/__main__.py` and `tools/submit_benchmark_job.py`.
+- Manifest-root precedence: CLI roots → `DYNACELL_MANIFEST_ROOTS` env
+  var → `dynacell.manifest_roots` entry points.
+- Collision policy: leaves with both `dataset_ref` and explicit
+  `data_path` raise `ValueError`.
+- Migrate exactly one target (`er_sec61b` + `ipsc_confocal` train_set)
+  to prove end-to-end composition is byte-identical to pre-PR output.
+
+Tests: `test_dataset_ref.py` (unit — resolver + error messaging),
+`test_compose.py` (viscy-utils resolver kwarg contract), expansion to
+`test_benchmark_config_composition.py` (integration, one migrated
+target). Full dynacell suite green.
+
+Exit criteria: one migrated leaf composes identically to today;
+remaining 16 train leaves + 8 predict leaves + 8 eval leaves untouched.
+
+### Stage 2 — Migrate remaining train/predict targets
+
+`mito_tomm20`, `membrane`, `nucleus` move onto `dataset_ref` in the
+train/predict overlays. Each is a small follow-up PR touching one target
+group file + one train_set file (if applicable) + any corresponding
+leaves that referenced them. Behavior stays identical; test suite
+verifies no drift.
+
+### Stage 3 — Extend resolver to Hydra / eval side
+
+The spec defers eval-side resolution. This stage closes it:
+
+- Extend the Pydantic manifest schema (or add a sibling) to cover
+  eval-specific fields: `gt_path`, `cell_segmentation_path`,
+  `gt_cache_dir`, `gt_channel_name`. These are dataset-specific, so the
+  manifest is the right owner.
+- Add a Hydra-side resolver hook. Options:
+  - A custom OmegaConf resolver that reads the manifest at compose
+    time, or
+  - A `dynacell.evaluation` pre-compose step that splices the manifest
+    fields into the composed dict before `pipeline.py` consumes it.
+- Update `pipeline_cache.py` and any callers so manifest access goes
+  through the same registry the train-side resolver uses.
+
+This is the architectural precondition for clean a549 eval leaves.
+Scope is contained (eval-side only) but requires Hydra + Pydantic + the
+resolver lib to agree on a single manifest shape.
+
+### Stage 4 — Migrate eval target YAMLs
+
+Strip `io.gt_path`, `io.cell_segmentation_path`, `io.gt_cache_dir`,
+`io.gt_channel_name` out of `_internal/shared/eval/target/*.yaml`.
+Those YAMLs keep only channel-name and organelle identity; paths come
+from the manifest via `benchmark.dataset_ref`.
+
+Existing eval leaves become thinner (they inherit `dataset_ref` from
+the training cell or declare their own), and the current 8 eval leaves
+continue to compose identically.
+
+### Stage 5 — Add a549 manifest
+
+Register `aics-a549-mantis` (slug TBD) in the manifest registry:
+
+- `data_path_train`, `data_path_test` per organelle target
+- `source_channel`, `target_channel`
+- `spacing` (voxel dimensions)
+- Eval-side fields: `gt_path`, `cell_segmentation_path`,
+  `gt_cache_dir`, `gt_channel_name`
+
+Lives in `dynacell-paper` (or wherever the canonical manifest source
+is). Independent of VisCy changes — can proceed in parallel with
+Stage 3.
+
+### Stage 6 — A549 leaf expansion
+
+With the resolver in place on both sides, each new leaf is 5-10 lines:
+
+```yaml
+# eval__a549_mantis.yaml
+# @package _global_
+defaults:
+  - override /target: er_sec61b
+benchmark:
+  dataset_ref: {dataset: aics-a549-mantis, target: sec61b}
+io:
+  pred_path: /hpc/.../sec61b_celldiff_on_a549.zarr
+save:
+  save_dir: /hpc/.../eval_sec61b_celldiff_on_a549
+```
+
+The expansion matrix:
+
+- Fill in every `<org>/<model>/ipsc_confocal/` with
+  `predict__a549_mantis.yml` + `eval__a549_mantis.yaml`.
+- Create `<org>/<model>/joint_ipsc_confocal_a549_mantis/` with
+  `train.yml` + `predict__ipsc_confocal.yml` +
+  `predict__a549_mantis.yml` + `eval__ipsc_confocal.yaml` +
+  `eval__a549_mantis.yaml`.
+- Corresponding `_internal/leaf/` symlinks for every new eval leaf.
+
+Sub-scope to decide when we get here (question A from earlier):
+
+- **(iv) full-but-predictable-only** — add predict/eval leaves only for
+  the 8 cells that have `<model>_predict.yml` overlays (celldiff,
+  unetvit3d × 4 organelles). Start here.
+- **(iii) full-all-models** — additionally create skeleton
+  `fcmae_vscyto3d_predict.yml`, `fnet3d_paper_predict.yml`,
+  `unext2_predict.yml` overlays. Defer unless needed.
+
+## Dependency graph
+
+```
+Stage 1 (resolver core + 1 migration)
+  └─> Stage 2 (migrate other train/predict targets)
+  └─> Stage 3 (eval-side resolver)
+          └─> Stage 4 (migrate eval target YAMLs)
+                  └─> Stage 6 (a549 leaf expansion)
+                          ^
+                          │
+                Stage 5 (a549 manifest) ─┘
+```
+
+Stages 1 → 2 → 3 → 4 → 6 are strictly sequential on the VisCy side.
+Stage 5 is independent and can proceed in parallel with Stages 1–3, as
+long as it lands before Stage 6.
+
+## Why not expand a549 first
+
+Tempting because the data work (Stage 5) is decoupled and a549
+experiments may be on the critical path for a paper. But writing a549
+leaves before the resolver means:
+
+- ~60 new YAMLs duplicate the paths the resolver will consolidate.
+- Eval target YAMLs get a549-variant clones, doubling the `target/`
+  group size (the thing Stage 4 is designed to shrink).
+- Every a549 leaf gets rewritten once the resolver lands, turning the
+  a549 PR into technical debt the moment it merges.
+
+If the research timeline forces Stage 5/6 before Stages 1–4 land, do it
+with eyes open: treat the hardcoded-path leaves as transitional and
+schedule the rewrite explicitly.
+
+## Non-goals for this roadmap
+
+- FOV-level split resolution (Phase 5D of the dynacell-paper refactor —
+  this is about *FOV membership*, not *dataset facts*).
+- New CLI flags on `dynacell fit` / `predict` — the resolver is implicit
+  via the composition hook.
+- Reporting-side path resolution — reporting consumes eval outputs, not
+  source data.
+- Changes to `_internal/shared/model/model_overlays/` or
+  `launcher_profiles/` — those are model/hardware concerns, orthogonal.

+# VisCy PR Spec: Manifest-Driven Dataset Reference Resolution
+
+## Goal
+
+Add a resolver to VisCy's config composition pipeline that turns `benchmark.dataset_ref: {dataset, target}` into concrete `data_path`, `source_channel`, `target_channel` — read from a Pydantic `DatasetManifest` YAML discovered via manifest roots. Zero changes to Lightning CLI, Hydra, or `submit_benchmark_job.py`'s public surface. Backward compatible.
+
+## Context
+
+Today, core dataset facts are duplicated:
+
+- **dynacell-paper** `configs/datasets/aics-hipsc/manifest.yaml` — canonical source of truth (data paths, channels, spacing, splits).
+- **VisCy** `_internal/shared/model/{train_sets,targets}/*.yml` — hardcodes `data_path`, `source_channel`, `target_channel`.
+
+If a zarr store moves, both sides need hand updates. The intent hook `benchmark.dataset_group: aics-hipsc` already sits in `train_sets/ipsc_confocal.yml` as a breadcrumb — nothing reads it.
+
+This PR closes the gap by wiring a resolver at the composition choke point (`viscy_utils.cli._maybe_compose_config` plus `submit_benchmark_job.py`).
+
+## Non-goals
+
+- Eval-side (Hydra) resolution. Eval uses Pydantic manifests already via `pipeline_cache.py`; a follow-up PR can make eval leaves `dataset_ref`-aware.
+- Collection-aware data loading (Phase 5D of the dynacell-paper refactor). This PR resolves *dataset facts*, not *FOV membership*.
+- Inventing a new CLI flag surface on `dynacell fit` / `predict`. Resolution is implicit via the composition hook.
+- Importing anything from `dynacell-paper`. The resolver is generic.
+
+## New types and functions
+
+**`applications/dynacell/src/dynacell/data/manifests.py`** — add one Pydantic model:
+
+```python
+class DatasetRef(BaseModel):
+    """Reference to a dataset target, resolved against a manifest registry."""
+
+    dataset: str
+    target: str
+    # Future: override: dict = {} for paper-specific store swaps. Not in v1.
+```
+
+**`applications/dynacell/src/dynacell/data/resolver.py`** — new module:
+
+```python
+class ManifestNotFoundError(LookupError): ...
+class TargetNotFoundError(LookupError): ...
+class NoManifestRootsError(RuntimeError): ...
+
+class ResolvedDataset(BaseModel):
+    """Flat view of the fields a leaf needs after ref resolution."""
+
+    manifest_path: Path         # for provenance / logging
+    data_path_train: Path
+    data_path_test: Path
+    source_channel: str
+    target_channel: str
+    spacing: VoxelSpacing
+
+def discover_manifest_roots(
+    cli_roots: list[Path] | None = None,
+) -> list[Path]:
+    """Resolve manifest roots in precedence order (see below).
+
+    Raises NoManifestRootsError if nothing is configured.
+    """
+
+def resolve_dataset_ref(
+    ref: DatasetRef,
+    roots: list[Path] | None = None,
+) -> ResolvedDataset:
+    """Load the manifest for `ref.dataset` and return the target's fields."""
+```
+
+**Manifest root precedence** (highest wins):
+
+1. `cli_roots` parameter (from the compose hook).
+2. `DYNACELL_MANIFEST_ROOTS` env var (colon-separated absolute paths).
+3. Python entry points under group `dynacell.manifest_roots`; each entry resolves to a package resource directory (e.g. `dynacell_paper._configs.datasets`).
+
+Scan logic: for each root (in order), look for `<root>/<dataset>/manifest.yaml`. First hit wins. No recursion, no globbing.
+
+## Composition hook
+
+**`packages/viscy-utils/src/viscy_utils/compose.py`** — add an optional post-composition hook:
+
+```python
+def load_composed_config(
+    path: Path,
+    *,
+    resolver: Callable[[dict], dict] | None = None,
+) -> dict:
+    """... existing docstring ...
+
+    If `resolver` is provided, it is called on the final merged dict
+    before returning. Resolvers are pure: given a dict, return a dict.
+    """
+```
+
+Keep the existing behavior when `resolver` is `None`. No mutation of `_seen` semantics.
+
+**`packages/viscy-utils/src/viscy_utils/cli.py`** — `_maybe_compose_config`:
+
+```python
+# after load_composed_config(path) returns:
+composed = load_composed_config(path, resolver=_dynacell_ref_resolver)
+# existing: strip reserved keys (launcher, benchmark) before writing tempfile
+```
+
+The resolver:
+
+```python
+def _dynacell_ref_resolver(composed: dict) -> dict:
+    ref_dict = composed.get("benchmark", {}).get("dataset_ref")
+    if ref_dict is None:
+        return composed                     # no-op for legacy leaves
+    ref = DatasetRef.model_validate(ref_dict)
+    mode = _infer_mode(composed)            # "fit" | "predict" | "validate"
+    resolved = resolve_dataset_ref(ref)
+    return _splice_resolved(composed, resolved, mode)
+```
+
+### Mode inference (predict vs fit store)
+
+`_infer_mode(composed)` order:
+
+1. If `composed["launcher"]["mode"]` set (benchmark leaves always set this), use it.
+2. Else inspect `sys.argv[1]` (`fit` / `predict` / `validate`).
+
+Splicing:
+
+- `mode == "fit"` or `"validate"` → `data.init_args.data_path = resolved.data_path_train`
+- `mode == "predict"` → `data.init_args.data_path = resolved.data_path_test`
+- Always: `data.init_args.source_channel = resolved.source_channel`
+- Always: `data.init_args.target_channel = resolved.target_channel`
+
+`benchmark.spacing` gets filled from `resolved.spacing.as_list()` (handy for eval and any metric-aware callbacks). Since `benchmark:` is stripped before Lightning sees it, this only matters for downstream consumers of the resolved intermediate dict.
+
+### Collision policy
+
+If the composed config has BOTH `benchmark.dataset_ref` AND an explicit `data.init_args.data_path` (or `source_channel` / `target_channel`), raise `ValueError` with both values. Do not silently override either way — the user is giving conflicting signals and should pick.
+
+Exception: predict mode leaves sometimes declare `data.init_args.data_path` pointing at the test store today. Those leaves must migrate to `dataset_ref` in the same PR OR be left alone — they can't do both.
+
+### `submit_benchmark_job.py` pickup
+
+Since it calls `load_composed_config()` on line 159, the resolver is applied automatically — **but only if we pass it through**. Change that call to `load_composed_config(path, resolver=_dynacell_ref_resolver)`. The topology validation (gpus × nodes × ntasks_per_node) runs on the already-resolved dict, which is fine.

+
+The viscy-utils changes stay generic (the `resolver` kwarg is a plain callable). The dynacell-specific resolver lives in `applications/dynacell/src/dynacell/_compose_hook.py` and is injected by dynacell's CLI entry points only. This keeps viscy-utils from depending on dynacell.
+
+## Test matrix
+
+**Unit (`test_dataset_ref.py`):**
+
+| Scenario | Expected |
+|---|---|
+| `resolve_dataset_ref` happy path (aics-hipsc/sec61b) | returns `ResolvedDataset` with correct paths |
+| unknown dataset | `ManifestNotFoundError` listing available datasets across roots |
+| unknown target within a known dataset | `TargetNotFoundError` listing available targets |
+| `DYNACELL_MANIFEST_ROOTS` unset + no entry points | `NoManifestRootsError` with install hint |
+| env var takes precedence over entry points | passes with env-var path |
+| invalid manifest YAML (missing `name`) | Pydantic `ValidationError`, file path in message |
+| `cli_roots` wins over env var and entry points | verified |
+
+**Integration (`test_benchmark_config_composition.py`):**
+
+| Scenario | Expected |
+|---|---|
+| `er/ipsc_confocal/celldiff/train.yml` composes with `dataset_ref` | resolved dict has `data_path_train`, correct channels |
+| same leaf with `launcher.mode: predict` swapped in | `data_path` resolves to test store |
+| leaf with `dataset_ref` + explicit `data_path` | `ValueError` on collision |
+| no `dataset_ref` in the composed config | resolver no-op; legacy path still works |
+| FCMAE pretrained/scratch parity | still only differs in encoder init |
+| topology invariants | still hold |
+
+**CLI routing (`test_cli_routing.py`):**
+
+- `dynacell fit -c <leaf>` → `_dynacell_ref_resolver` is wired into `load_composed_config`.
+- Hydra subcommands (`evaluate`, `report`, `precompute-gt`) — unchanged, no hook injected. (Eval-side is out of scope per "Non-goals".)
+
+**viscy-utils tests (`test_compose.py`):**
+
+- `load_composed_config` with `resolver=None` behaves exactly as before.
+- `resolver=lambda d: d` roundtrip identity.
+- `resolver` receives the post-merge dict, not per-base fragments.
+
+## Backward compatibility
+
+- Leaves with no `benchmark.dataset_ref`: unchanged behavior.
+- Leaves with explicit `data_path` and no `dataset_ref`: unchanged behavior.
+- The `compose.load_composed_config` signature gains a keyword-only arg with default `None`; existing callers are unaffected.
+- `viscy_utils` remains generic — it calls whatever resolver is passed, so other consumers can register their own.
+
+## Failure-mode messaging (explicit)
+
+Because the most common new failure will be "I ran `dynacell fit` and got an unhelpful error":
+
+```
+NoManifestRootsError: No dynacell manifest roots configured.
+
+Configure via one of:
+  - CLI flag:       --manifest-root /path/to/datasets
+  - Env var:        export DYNACELL_MANIFEST_ROOTS=/path/to/datasets
+  - Install a provider:  pip install dynacell-paper
+
+Leaf config at /path/to/leaf.yml references:
+  benchmark.dataset_ref: {dataset: aics-hipsc, target: sec61b}
+```
+
+```
+ManifestNotFoundError: dataset 'aics-hipsc' not found in manifest roots.
+
+Searched:
+  - /hpc/.../dynacell_paper/_configs/datasets     (no aics-hipsc/manifest.yaml)
+  - /tmp/my-roots                                 (no aics-hipsc/manifest.yaml)
+
+Available datasets across configured roots:
+  - (none)
+```
+
+## Migration plan (in-PR)
+
+1. Land the resolver + tests with all existing leaves untouched. Full test suite green.
+2. Migrate ONE target in the same PR: `er_sec61b.yml` + `ipsc_confocal.yml` — prove end-to-end composition produces an identical final dict to today (byte-for-byte if possible; modulo field ordering).
+3. Tail PRs (not this one) migrate `tomm20`, `membrane`, `nucleus`, and the mantis_lightsheet train_set when it lands.
+
+## Open questions for review
+
+1. **Should the resolver be part of viscy-utils, or purely in `applications/dynacell`?** This spec keeps the `resolver` kwarg in viscy-utils (generic) but the dynacell-specific resolver function in `applications/dynacell`. Alternative: promote the resolver concept as part of `viscy-utils`. I'd keep it generic (the viscy-utils kwarg takes any callable).
+2. **Entry point group name**: `dynacell.manifest_roots` is specific; `viscy.dataset_registries` is generic. Since the schema is dynacell-specific even though it lives in VisCy, I'd go with `dynacell.manifest_roots`.
+3. **Should `benchmark.dataset_ref` stay in the final dict (it gets stripped anyway) or get moved to a resolver-only key**? Staying under `benchmark:` is cleanest because it already gets stripped and has provenance value before strip. Keep it there.
+
+## Downstream (dynacell-paper) companion PR
+
+After this lands in VisCy, the dynacell-paper side change is small:
+
+1. Add the entry point in `pyproject.toml`:
+   ```toml
+   [project.entry-points."dynacell.manifest_roots"]
+   default = "dynacell_paper._configs.datasets"
+   ```
+2. Smoke test: `dynacell fit -c <VisCy leaf with dataset_ref> --trainer.fast_dev_run=true` resolves paths when `dynacell-paper` is installed.
+3. No changes to manifest YAML content.

Subject: [PATCH 156/311] refactor(dynacell): strict dataset_ref collision +
 shared manifest-root fixture

Resolve drift from the Stage 1 plan: source_channel moves out of the
shared ipsc_confocal train/predict fragments and onto each target
fragment (mito/nucleus/membrane), since dataset_ref is the single
source of truth for data_path/source_channel/target_channel on
migrated ER leaves. Restore the strict collision check that raises
whenever a composed fragment also declares a resolved field, dropping
the agreement-tolerant transitional policy.

Also: cache load_manifest with lru_cache (same policy as
_load_yaml_cached); move DatasetManifest.source_channel validation
onto the schema; delete the unused _DATA_FIELDS constant; rename a
shadowing loop variable in the conflict-details comprehension; switch
DYNACELL_MANIFEST_ROOTS parsing to os.pathsep; consolidate the
autouse manifest-root fixture into conftest.py.

Subject: [PATCH 157/311] test(dynacell): add nucleus and membrane fixture
 manifest targets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors the companion dynacell-paper manifest additions so that Stage 2
resolver tests can splice data_path / target_channel for the two
multi-marker targets derived from cell.zarr. No production-side effect
— the fixture is consumed only by the autouse test conftest.

Subject: [PATCH 158/311] refactor(dynacell): migrate mito/nucleus/membrane
 targets to dataset_ref
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Stage 2 of the A549 expansion roadmap. Each target fragment now
declares benchmark.dataset_ref.target and drops its hardcoded
data_path / source_channel / target_channel; the resolver splices
concrete values from the manifest (either the repo-local fixture in
tests or the dynacell-paper canonical manifest at runtime). The 6
non-ER predict leaves drop their explicit data.init_args.data_path
for the same reason — strict collision would otherwise raise.

Tests swap the mito-only partial-ref no-op parity pair for
parametrized resolver tests that cover every model in TRAIN_LEAVES /
PREDICT_LEAVES composing a migrated fragment (pytest.skip handles
missing FCMAE leaves for nucleus/membrane). The roadmap Stage 2
paragraph is updated to match the batched single-PR shape.

Requires the dynacell-paper companion PR to land before production
nucleus/membrane runs — VisCy CI is self-contained via the fixture.

Subject: [PATCH 159/311] test(dynacell): consolidate dataset_ref resolver
 tests across migrated organelles

Collapses the ER-specific train/predict resolver tests and the parametrized
non-ER block into unified table-driven tests keyed off a single
_MIGRATED_TARGET_INFO dict. Eliminates duplicate skip/fixture setup and the
N=5 model sub-parametrization that existed solely to accommodate
pytest.skip for non-existent leaves.

Subject: [PATCH 160/311] feat(dynacell): add Hydra-side dataset_ref hook
 module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends StoreLocations with gt_cache_dir: Path | None, and extends
ResolvedDataset + resolve_dataset_ref to surface cell_segmentation_path
and gt_cache_dir alongside the existing manifest fields. Adds a
Hydra-side apply_dataset_ref hook in evaluation/_ref_hook.py that
mirrors the Lightning-side compose hook: partial refs are no-ops,
collisions raise ValueError, and _splice writes io.* + derived
pred_channel_name + pixel_metrics.spacing into a DictConfig.

Introduced as unused code — the hook is only wired at eval/precompute
entry points in the follow-up commit, which keeps this change
bisect-safe. Fixture manifest now carries gt_cache_dir on all four
targets so the next commit's integration tests can assert resolved
values byte-for-byte against the pre-migration hardcoded paths.

Subject: [PATCH 161/311] refactor(dynacell): wire Hydra dataset_ref hook;
 migrate eval configs

Wires apply_dataset_ref at the top of evaluate_model and precompute_gt,
and extends the __main__ Hydra branch with the same
ManifestNotFound/NoManifestRoots/TargetNotFound catch the Lightning
branch already has. Sets HYDRA_FULL_ERROR=1 so @hydra.main does not
swallow resolver errors before our clean SystemExit(2) catch.

Migrates all four eval target YAMLs (er_sec61b, mito_tomm20, nucleus,
membrane) plus predict_set/ipsc_confocal.yaml together so io.* and
pixel_metrics.spacing come from the manifest via benchmark.dataset_ref.
Adds benchmark: null placeholder to eval.yaml so struct-mode merges
accept the new key. Nucleus and membrane share cell.zarr but get
distinct gt_cache_dir paths, keyed by organelle not channel.

Test coverage: integration tests compose every canonical eval leaf and
verify splice output (Layer 1) and invoke evaluate_model.__wrapped__ /
precompute_gt.__wrapped__ to prove the hook is actually wired at both
@hydra.main entry points (Layer 2). Router tests assert clean SystemExit(2)
with the expected stderr for all three resolver error classes on both
evaluate and precompute-gt.

Companion dynacell-paper manifest bump adds gt_cache_dir to the
canonical aics-hipsc manifest; safe to merge either order because
Pydantic extra='ignore' makes the field optional.

-### Stage 3 — Extend resolver to Hydra / eval side
-
-The spec defers eval-side resolution. This stage closes it:
-
-- Extend the Pydantic manifest schema (or add a sibling) to cover
-  eval-specific fields: `gt_path`, `cell_segmentation_path`,
-  `gt_cache_dir`, `gt_channel_name`. These are dataset-specific, so the
-  manifest is the right owner.
-- Add a Hydra-side resolver hook. Options:
-  - A custom OmegaConf resolver that reads the manifest at compose
-    time, or
-  - A `dynacell.evaluation` pre-compose step that splices the manifest
-    fields into the composed dict before `pipeline.py` consumes it.
-- Update `pipeline_cache.py` and any callers so manifest access goes
-  through the same registry the train-side resolver uses.
-
-This is the architectural precondition for clean a549 eval leaves.
-Scope is contained (eval-side only) but requires Hydra + Pydantic + the
-resolver lib to agree on a single manifest shape.
-
-### Stage 4 — Migrate eval target YAMLs
-
-Strip `io.gt_path`, `io.cell_segmentation_path`, `io.gt_cache_dir`,
-`io.gt_channel_name` out of `_internal/shared/eval/target/*.yaml`.
-Those YAMLs keep only channel-name and organelle identity; paths come
-from the manifest via `benchmark.dataset_ref`.
-
-Existing eval leaves become thinner (they inherit `dataset_ref` from
-the training cell or declare their own), and the current 8 eval leaves
-continue to compose identically.
+### Stage 3 — Hydra-side hook + migrate all four eval target YAMLs
+
+Extend `dataset_ref` resolver to the Hydra/eval side. Add post-compose
+hook (`_ref_hook.py`) at `evaluate_model` / `precompute_gt` entry
+points. Migrate all four eval target YAMLs (`er_sec61b`, `mito_tomm20`,
+`nucleus`, `membrane`) + `predict_set/ipsc_confocal.yaml` together so
+`io.*` and `pixel_metrics.spacing` come from the manifest. Add
+`gt_cache_dir` to `StoreLocations`.
+
+Deliverables:
+
+- New `applications/dynacell/src/dynacell/evaluation/_ref_hook.py`.
+  The hook fires inside the `evaluate_model()` and `precompute_gt()`
+  entry-point function bodies (not during Hydra compose), reads
+  `composed["benchmark"]["dataset_ref"]`, and splices the manifest
+  fields into the composed config before `pipeline.py` consumes it.
+- `ResolvedDataset` extended with `cell_segmentation_path` and
+  `gt_cache_dir` fields.
+- Four migrated eval target YAMLs (`_internal/shared/eval/target/*.yaml`):
+  each keeps only `target_name` and `benchmark.dataset_ref.target`;
+  `io.gt_path`, `io.cell_segmentation_path`, `io.gt_channel_name`,
+  `io.pred_channel_name`, `io.gt_cache_dir` all come from the manifest.
+  `pred_channel_name` is derived in the hook as
+  `f"{target_channel}_prediction"` and is not stored in the manifest.
+- Migrated `_configs/predict_set/ipsc_confocal.yaml`: contributes only
+  `benchmark.dataset_ref.dataset`; `pixel_metrics.spacing` comes from
+  the manifest.
+- `benchmark: null` placeholder added to `_configs/eval.yaml` so the
+  node exists for the hook to populate.
+- Hydra-branch error catch wired into `dynacell/__main__.py` so hook
+  errors surface as user-facing messages.
+- Integration tests extended with Layer 2 entry-point wiring coverage
+  (the hook actually runs through `evaluate_model` / `precompute_gt`,
+  not just called directly).
+
+The `gt_cache_dir` addition to `StoreLocations` requires a companion
+bump to the canonical `dynacell-paper` manifest — see the planned
+spec at `~/.claude/plans/dynacell-paper-stage3-gt-cache-dir.md` (or a
+companion spec if the path hasn't been published yet). Pydantic's
+default `extra="ignore"` on `StoreLocations` makes the ordering
+constraint an auditing preference, not a schema-parsing requirement —
+older manifests without `gt_cache_dir` still parse.

+### Shared `gt_cache_dir` race
+
+Resolving `io.gt_cache_dir` from the manifest means the default workflow writes to a shared location like `/hpc/projects/.../eval_cache/SEC61B`. `flush_manifest` and the per-artifact writers in `pipeline_cache.py` are not lock-protected, so two concurrent `dynacell precompute-gt` runs on the same target will race on the manifest.
+
+Workarounds:
+- Serialize your precompute runs manually per target (the current paper workflow).
+- Override `io.gt_cache_dir=/scratch/me/cache/X` at the CLI to write to a private directory. The hook's strict collision check accepts this override as long as no conflicting value from the manifest is in play.

Subject: [PATCH 162/311] refactor(dynacell): dedup dataset_ref hooks and test
 setup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Factors the partial-ref no-op + Pydantic validation pipeline shared by
_compose_hook and _ref_hook into a single dataset_ref_from_dict helper
on dynacell.data.resolver, so REQUIRED_REF_KEYS lives in exactly one
place and both hook surfaces use identical semantics (ValidationError
propagates as-is rather than being rewrapped).

Restores the caller's struct-mode state in _splice via try/finally so
the hook no longer silently unlocks the whole Hydra config for the
rest of evaluate_model / precompute_gt.

Test cleanup: promotes clear_global_hydra to a shared conftest fixture
(deletes the two local copies), drops the redundant
DYNACELL_MANIFEST_ROOTS setenv calls now that conftest autouses it,
removes the dead _FIXTURE_ROOT module constants, drops the
_clear_manifest_cache autouse (the path-keyed lru cache is already
stable across tests), and aligns the null-dataset scenario on the
pydantic.ValidationError the hook now surfaces.

YAML cleanup: deletes the WHAT-narrating header blocks from the four
migrated eval target YAMLs, predict_set/ipsc_confocal.yaml, and
eval.yaml — the behavior is already visible from dataset_ref + the
hook module, so the comments added noise without WHY.

Subject: [PATCH 164/311] chore(dynacell): bump 4gpu mem 512G -> 1024G after
 two OOM deaths
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Jobs 31287777 (ER/SEC61B FCMAE scratch) and 31297033 (mito/TOMM20
FCMAE scratch) both OOM-died in the cgroup mid-training at ~24h
with the 512G --mem budget. The structural bill is ~80 GiB
/dev/shm mmap_preload + 4 ranks × ~58 GiB steady-state RSS +
persistent DataLoader workers, leaving ~200 GiB of transient
headroom — validation-time spikes tipped one rank over. H200
nodes have 2 TB host memory; 1024G doubles the cgroup budget
without changing throughput-critical knobs.

Subject: [PATCH 165/311] fix(viscy-data): let BatchedConcatDataset tolerate
 single-sample children
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BatchedConcatDataset.__getitems__ unconditionally called
self.datasets[dataset_idx].__getitems__(sample_indices), which
AttributeError'd out the moment any child dataset only implemented
__getitem__ — notably SlidingWindowDataset, whose per-sample retry
logic for nonzero-fraction filtering doesn't map cleanly to a batched
read. This meant the "HCSDataModule children under
BatchedConcatDataModule" combination couldn't even start a training
step, blocking any cross-experiment joint training via the
concat-dataset fast path.

Introduce a _batched_get helper that prefers __getitems__ (keeps the
TripletDataset amortized-I/O path intact) and falls back to a loop of
__getitem__ + _collate_samples for datasets with only single-sample
semantics. Add a regression test that iterates one training batch
through BatchedConcatDataModule over two HCSDataModule children and
asserts the expected per-child micro-batch shape.

Subject: [PATCH 166/311] refactor(viscy-data): drop :class: markup, assert
 lossless batch grouping

Style: the ``_batched_get`` docstring used Sphinx ``:class:`` cross-refs
inconsistent with every other docstring in combined.py (plain backticks).
Tightens consistency so numpy-style rendering stays uniform.

Test: add a batch-size-sum assertion to the BatchedConcatDataModule
regression test. Total per-child micro-batch B dims must equal the
DataLoader's configured batch_size=4, catching any future regression
where grouping drops or duplicates samples without over-specifying the
shuffle-dependent per-child split.

Subject: [PATCH 167/311] feat(viscy-data): attach ShardedDistributedSampler in
 BatchedConcatDataModule
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Stage 7 prerequisite for joint multi-dataset training (ipsc_confocal +
a549_mantis): give BatchedConcatDataModule the same DDP boundary
CachedConcatDataModule and GPUTransformDataModule already have. Detect
DDP via torch.distributed.is_initialized() and attach
ShardedDistributedSampler directly on the train/val ThreadDataLoader.

Since ShardedDistributedSampler subclasses DistributedSampler, Lightning
skips its own sampler injection (data_connector only wraps samplers
that are *not* already DistributedSampler), so
trainer.use_distributed_sampler: false becomes optional style rather
than a correctness prerequisite.

Tests: sampler attachment, micro-batch contract preservation under DDP
(train + val), and rank-disjointness at the datamodule level. DDP is
simulated via monkeypatched torch.distributed primitives — no real
process group required.

Subject: [PATCH 168/311] feat(viscy-utils): add configure_adamw_scheduler
 helper

Extract the AdamW + WarmupCosine/Constant scheduler factory so cytoland,
dynacell, and future apps can share one optimizer setup. Exposes
warmup_steps and warmup_multiplier as explicit kwargs (previously
hardcoded) and raises on unknown schedules instead of silently
falling through.

Subject: [PATCH 169/311] refactor(dynacell): use shared optimizer helper;
 expose warmup knobs

Drop the private _configure_adamw_scheduler in favor of the shared
viscy_utils.optimizers.configure_adamw_scheduler. Surface warmup_steps
and warmup_multiplier on DynacellUNet and DynacellFlowMatching so
YAML overlays can tune them; set them to ~1 epoch on the benchmark
virtual-staining fit overlays (celldiff, fcmae_vscyto3d, unetvit3d,
unext2) to match the cosine schedule over the actual training length.

Subject: [PATCH 170/311] refactor(cytoland): adopt shared optimizer helper and
 ckpt_path hparam hygiene

Replace VSUNet's inline AdamW + WarmupCosine/Constant setup with
viscy_utils.optimizers.configure_adamw_scheduler; keep the
freeze_encoder requires_grad_ step inline since it's cytoland-specific.
Surface warmup_steps and warmup_multiplier as init args so YAML
overlays can tune the cosine ramp.

Also add ckpt_path to save_hyperparameters(ignore=...) so a one-shot
weight-load path isn't persisted into the checkpoint hparams, matching
DynacellUNet and FcmaeUNet.

Subject: [PATCH 171/311] chore(cytoland): default vscyto3d finetune to
 bf16-mixed

bf16 avoids the loss-scaling failure modes of fp16 and is generally
preferred on Ampere/Hopper GPUs where the vscyto3d finetune runs;
matches the dynacell benchmark fit overlays.

Subject: [PATCH 172/311] refactor(dynacell): split fit overlays into
 model+trainer vs HCS data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extracts each _internal/shared/model/model_overlays/<model>_fit.yml's
data: block into a sibling data_overlays/<model>_fit.yml fragment.
The fit overlay now owns only base: + model: + trainer:; the new
data_overlays/ fragment owns data.init_args.* (batch_size,
z_window_size, yx_patch_size, num_workers, augmentations,
gpu_augmentations, val_gpu_augmentations, and the fnet3d-specific
normalizations override).

Context: Stage 7 prerequisite for joint ipsc_confocal + a549_mantis
training per A549_EXPANSION_ROADMAP.md and
MULTI_DATASET_TRAINING_RECOMMENDATION.md. Joint train leaves will use
BatchedConcatDataModule with two explicit child HCSDataModule blocks;
batch_size and friends belong on each child, not at the top level. The
pre-split overlays would have dropped those single-store data hparams
into the wrong nesting depth when composed by a joint leaf.

Single-store leaves now compose both halves in order
train_sets → targets → data_overlays → model_overlays → launcher_profiles,
preserving the existing merge precedence (model-recipe data hparams
override target-level defaults; leaf-level overrides in the two
fnet3d_paper nucleus/membrane leaves still win at the end). Parity test
extends TRAIN_LEAVES parametrization to assert every leaf still
composes to its model's expected batch_size, z_window_size,
yx_patch_size, num_workers, plus a non-empty gpu_augmentations.

Subject: [PATCH 173/311] docs(dynacell): add job submission reliability plan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Capture the v2.4 plan that closes two gaps surfaced by the 2026-04-21
NCCL hangs on gpu-d-1 (four sibling FCMAE jobs each burned ~1 h on the
30-min PyTorch watchdog timeout): make `--exclude` an optional SBATCH
directive so operators can steer around bad nodes, and add a pre-flight
NCCL smoke test so broken intra-node peer links abort in ~60 s instead
of ~30 min. Gap 2 (auto-requeue) is explicitly deferred — plan for it is
preserved in-line for future pickup after a Slurm requeuehold probe.

+# Dynacell Job Submission — Reliability Plan
+
+Plan to close 3 gaps in `applications/dynacell/tools/submit_benchmark_job.py` +
+`sbatch_template.sbatch` exposed by the 2026-04-21 NCCL hangs on `gpu-d-1`
+(4 sibling FCMAE jobs wasted ~1 h each on a 30-min NCCL watchdog timeout
+before aborting).
+
+**Scope (v2.4):** Gap 1 + Gap 3 only. Gap 2 (auto-requeue on NCCL watchdog
+hang) is **deferred** — plan preserved below for future pickup, but not
+implemented this round. Files touched this round: `submit_benchmark_job.py`,
+`sbatch_template.sbatch`, new `nccl_smoke_test.py`, and the test file. No
+behavior change for jobs that run cleanly.
+
+**v2.4 — updated 2026-04-21 after deferring Gap 2.** Changes listed in
+[Appendix: Review findings addressed](#appendix-review-findings-addressed).
+
+---
+
+## Gap 1 — `--exclude` as optional SBATCH directive
+
+**Decision:** mirror how `constraint` is handled. `exclude` is optional,
+renders as `--exclude=<value>` when set, skipped when null/absent.
+
+**Changes to `applications/dynacell/tools/submit_benchmark_job.py`:**
+
+```python
+_SBATCH_DIRECTIVE_ORDER = (
+    ("job_name", "--job-name"),
+    ("time", "--time"),
+    ("nodes", "--nodes"),
+    ("ntasks_per_node", "--ntasks-per-node"),
+    ("partition", "--partition"),
+    ("cpus_per_task", "--cpus-per-task"),
+    ("gpus", "--gpus"),
+    ("mem", "--mem"),
+    ("constraint", "--constraint"),
+    ("exclude", "--exclude"),     # NEW
+)
+
+_OPTIONAL_SBATCH_DIRECTIVES = frozenset({"constraint", "exclude"})
+```
+
+Rendering already handles null via `_OPTIONAL_SBATCH_DIRECTIVES`; the
+`--constraint` quoting branch stays as-is (don't quote `--exclude`, SLURM
+accepts bare comma-separated hostlists).
+
+**Usage** — either set in a profile, in the leaf, or via `--override`:
+
+```sh
+uv run python .../submit_benchmark_job.py <leaf.yml> \
+    --override launcher.sbatch.exclude=gpu-d-1
+```
+
+**Tests** (extend `applications/dynacell/tests/test_submit_benchmark_job.py`):
+
+- `exclude="gpu-d-1"` → rendered output contains `#SBATCH --exclude=gpu-d-1`
+  and this line appears after `#SBATCH --constraint=...` and before
+  `#SBATCH --output=...` (content-based, not positional `[-1]`).
+- `exclude=None` or absent → no `--exclude` substring in rendered output.
+- Use content-based assertions (`"--exclude=" in rendered`, line-search) so
+  future optional directives don't break the test.
+
+**Verify:**
+`uv run pytest applications/dynacell/tests/test_submit_benchmark_job.py -k exclude`
+
+---
+
+## Gap 2 — auto-requeue on NCCL watchdog hang [DEFERRED]
+
+> **DEFERRED in v2.4.** Not implementing this round. The full plan below is
+> preserved as-is (four rounds of review) so it can be picked up later without
+> re-derivation. Implementing Gap 1 + Gap 3 alone still closes the motivating
+> failure mode: Gap 3's preflight kills bad-node jobs in ~60 s instead of
+> burning a 30-min NCCL watchdog, and Gap 1 lets the operator add
+> `--exclude=gpu-d-1` on the manual resubmit. The `#SBATCH --requeue`
+> directive and all shell shared-vars (ERR_LOG / BAD_LIST / COUNTER_FILE /
+> PREFLIGHT_MARKER / MAX_REQUEUE) are **not** added to the template in v2.4
+> — they only exist to serve the requeue path below.
+
+**Decisions:**
+
+1. **Single-node only.** Guard on `$SLURM_JOB_NUM_NODES -eq 1`. On
+   multi-node jobs, exit with the original rc — no auto-requeue. Our hardware
+   profiles are all `nodes: 1` today; when/if a multi-node profile lands, the
+   bad-node identification strategy must be revisited (parse the `[Rank N]`
+   hostname from the watchdog stderr line).
+2. **Trust `$SLURM_JOB_NODELIST`**, not `squeue`. It's set at allocation time,
+   stable across state transitions, and matches a single hostname on
+   single-node jobs.
+3. **Counter in a file under `run_root/slurm/`**, keyed on `$SLURM_JOB_ID`.
+   `SLURM_RESTART_COUNT` is unreliable across `scontrol requeue` — some Slurm
+   configs don't increment it on manual requeues.
+4. **Disable the EXIT trap before `scontrol requeue`.** Requeued jobs keep
+   the same `$SLURM_JOB_ID`, so the existing trap's
+   `rm -rf /dev/shm/$SLURM_JOB_ID` would wipe the mmap preload cache that the
+   requeued run expects to reuse (`scratch_dir: /dev/shm`, `mmap_preload:
+   true` in the ipsc_confocal train set).
+5. **Use `scontrol requeuehold` → `update ExcNodeList` → `release`**, not
+   `update` on a RUNNING job. Some Slurm versions reject `ExcNodeList` updates
+   while the job is RUNNING. Requeuehold parks the job in held-pending,
+   guaranteeing the update applies before scheduling.
+6. **Record preflight failures in a separate marker file**, not the Slurm
+   stderr. Writing to `%j.err` races with slurmstepd, and pollutes the user's
+   error log.
+
+**Changes to `applications/dynacell/tools/sbatch_template.sbatch`:**
+
+Add `#SBATCH --requeue` as a **literal line directly in the template**,
+immediately after the `@@sbatch_directives` substitution line. `--requeue` is
+valueless and always-on for dynacell jobs (no per-leaf configurability), so
+it belongs in the template next to the other always-on scaffolding (`umask
+0002`, `ml uv`, cleanup trap) — not routed through
+`_render_sbatch_directives()`, which only emits keyed directives from
+`_SBATCH_DIRECTIVE_ORDER`.
+
+Concretely, the top of the template becomes:
+
+```bash
+#!/bin/bash
+
+@@sbatch_directives
+#SBATCH --requeue
+```
+
+**No change to `submit_benchmark_job.py` for the `--requeue` directive.**
+`_SBATCH_DIRECTIVE_ORDER` stays keyed-only. If we ever need another valueless
+SBATCH directive, we can either add another literal line or extend the
+render function — but not for this change.
+
+Declare shared vars **near the top of the script body** (before the preflight
+block from Gap 3) so Gap 3 and Gap 2 can reference them:
+
+```bash
+ERR_LOG=@@run_root/slurm/${SLURM_JOB_ID}.err
+BAD_LIST=@@run_root/slurm/${SLURM_JOB_ID}.bad_nodes
+COUNTER_FILE=@@run_root/slurm/${SLURM_JOB_ID}.requeue_count
+PREFLIGHT_MARKER=@@run_root/slurm/${SLURM_JOB_ID}.preflight_failed
+MAX_REQUEUE=3
+
+mkdir -p @@run_root/slurm
+```
+
+Replace the tail `srun ...` with (order: preflight → main srun → requeue
+decision):
+
+```bash
+# --- (Gap 3 preflight block goes here, may set PREFLIGHT_MARKER + SRUN_RC=134) ---
+
+if [ ! -f "$PREFLIGHT_MARKER" ]; then
+    srun uv run python -m dynacell @@mode --config @@resolved_config
+    SRUN_RC=$?
+fi
+
+# Requeue decision. Scope: single-node, watchdog signature matched, under cap.
+REQUEUE_COUNT=$(cat "$COUNTER_FILE" 2>/dev/null || echo 0)
+SHOULD_REQUEUE=0
+if [ "$SRUN_RC" -ne 0 ] && [ "$REQUEUE_COUNT" -lt "$MAX_REQUEUE" ] \
+   && [ "${SLURM_JOB_NUM_NODES:-1}" -eq 1 ]; then
+    if [ -f "$PREFLIGHT_MARKER" ] \
+       || grep -q "Watchdog caught collective operation timeout" "$ERR_LOG" 2>/dev/null; then
+        SHOULD_REQUEUE=1
+    fi
+fi
+
+if [ "$SHOULD_REQUEUE" -eq 1 ]; then
+    BAD_NODE=$SLURM_JOB_NODELIST
+    echo "$BAD_NODE" >> "$BAD_LIST"
+    NEW_EXCL=$(sort -u "$BAD_LIST" | paste -sd,)
+    echo $((REQUEUE_COUNT + 1)) > "$COUNTER_FILE"
+    echo "[auto-requeue] NCCL hang on $BAD_NODE; requeue $((REQUEUE_COUNT+1))/$MAX_REQUEUE, excl: $NEW_EXCL" >&2
+    # Clear preflight marker so the requeued job re-runs preflight.
+    rm -f "$PREFLIGHT_MARKER"
+    # Disable cleanup trap so /dev/shm/$SLURM_JOB_ID (mmap cache) survives
+    # the requeued run (same SLURM_JOB_ID reused on `scontrol requeue`).
+    trap - EXIT
+
+    # Explicit state machine for the Slurm mutation sequence. Requirements:
+    #   1. If requeuehold succeeds, ALWAYS attempt release before exiting,
+    #      else the job stays stuck in held-pending forever.
+    #   2. Only exit 0 when all three steps succeed (requeue actually took
+    #      effect with the exclusion applied).
+    #   3. On any failure, fall through to cleanup + exit $SRUN_RC so the
+    #      failure stays visible in Slurm accounting.
+    REQUEUE_OK=0
+    if scontrol requeuehold "$SLURM_JOB_ID"; then
+        if scontrol update JobId="$SLURM_JOB_ID" ExcNodeList="$NEW_EXCL" \
+           && scontrol release "$SLURM_JOB_ID"; then
+            REQUEUE_OK=1
+        else
+            # requeuehold succeeded but update or release failed — do NOT leave
+            # the job held. Best-effort release; warn if even that fails so the
+            # operator can manually `scontrol release $JID`.
+            scontrol release "$SLURM_JOB_ID" \
+                || echo "[auto-requeue] WARNING: job remains held; run: scontrol release $SLURM_JOB_ID" >&2
+        fi
+    fi
+
+    if [ "$REQUEUE_OK" -eq 1 ]; then
+        exit 0
+    fi
+    echo "[auto-requeue] scontrol sequence failed; exiting with rc=$SRUN_RC so failure stays visible" >&2
+    # Trap was disabled above; run cleanup manually before exiting so
+    # /tmp/$SLURM_JOB_ID and /dev/shm/$SLURM_JOB_ID don't leak on the
+    # non-requeued failure path.
+    cleanup
+fi
+
+exit $SRUN_RC
+```
+
+**Assumption to verify before shipping Gap 2:** on our Slurm install,
+`scontrol requeuehold` + `update ExcNodeList` + `release` reliably applies
+the exclusion to the next run. Probe once with a dummy job before enabling
+this path. If the probe fails, fall back to appending to `bad_nodes.log` only
+and require operator resubmit (Gap 1 unblocks this fallback).
+
+**Verify:** dry-render the template (`--print-script` on a known leaf), diff
+against the previous version; ensure the main srun line, cleanup trap, and
+`@@resolved_config` substitution are intact.
+
+---
+
+## Gap 3 — pre-flight NCCL smoke test
+
+**Decisions:**
+
+1. **Absolute path to the smoke test**, injected via a new `@@repo_root`
+   template substitution. The rendered sbatch does not `cd` and sbatch is
+   submitted from arbitrary CWDs — relative paths break.
+2. **Map Slurm env vars to torch.distributed env vars in the Python script**,
+   not the shell. Slurm sets `SLURM_PROCID`, `SLURM_NTASKS`, `SLURM_LOCALID`;
+   `torch.distributed.init_process_group(backend="nccl", init_method="env://")`
+   needs `RANK`, `WORLD_SIZE`, `LOCAL_RANK`. Doing the mapping in Python keeps
+   the template slim and testable.
+3. **Per-job deterministic `MASTER_PORT`** derived from `$SLURM_JOB_ID`, same
+   pattern Lightning's `SLURMEnvironment` uses — avoids collisions when two
+   jobs share a host.
+4. **Unset `MASTER_ADDR`/`MASTER_PORT` before the main srun** so Lightning's
+   SLURMEnvironment can set them itself without inheriting preflight values.
+5. **Preflight failure exits the script immediately** (v2.4). With Gap 2
+   deferred, there is no marker file and no auto-requeue — the job fails with
+   the smoke-test's non-zero rc, and the operator resubmits manually (using
+   `--override launcher.sbatch.exclude=...` from Gap 1 if needed). If/when
+   Gap 2 is picked up, swap `exit $SMOKE_RC` for `touch "$PREFLIGHT_MARKER";
+   SRUN_RC=$SMOKE_RC` so the requeue decision block downstream can handle it.
+
+**Submitter changes** — `applications/dynacell/tools/submit_benchmark_job.py`
+around the current `SbatchTemplate(...).substitute(...)` call:
+
+```python
+repo_root = Path(__file__).resolve().parents[3]  # VisCy/
+
+rendered = SbatchTemplate(template_text).substitute(
+    sbatch_directives=_render_sbatch_directives(job_name, str(run_root), sbatch),
+    run_root=str(run_root),
+    env_block=_render_env_block(env),
+    mode=mode,
+    resolved_config=str(resolved_path),
+    repo_root=str(repo_root),     # NEW
+)
+```
+
+**New file `applications/dynacell/tools/nccl_smoke_test.py`:**
+
+```python
+"""60-second NCCL all-reduce smoke test for dynacell training preflight.
+
+Maps Slurm's per-task env vars (SLURM_PROCID, SLURM_NTASKS, SLURM_LOCALID) to
+the env:// init variables torch.distributed expects (RANK, WORLD_SIZE,
+LOCAL_RANK), then runs a single all_reduce + barrier with a 60-second init
+timeout. Exits non-zero (via unhandled RuntimeError, which is the intended
+signal per project "prefer raising errors" policy) on hang or any NCCL error.
+"""
+
+from __future__ import annotations
+

+import sys
+from datetime import timedelta
+
+import torch
+import torch.distributed as dist
+
+
+def main() -> int:
+    """Initialize NCCL, all_reduce a ones tensor, barrier, and exit."""
+    os.environ.setdefault("RANK", os.environ["SLURM_PROCID"])
+    os.environ.setdefault("WORLD_SIZE", os.environ["SLURM_NTASKS"])

+    dist.destroy_process_group()
+    return 0
+
+
+if __name__ == "__main__":
+    sys.exit(main())
+```
+
+**Template preflight block** — inserted **before** the existing
+`srun uv run python -m dynacell ...` line (no shared-vars prerequisite in
+v2.4 since Gap 2 is deferred):
+
+```bash
+export MASTER_ADDR=$(scontrol show hostnames $SLURM_JOB_NODELIST | head -n1)
+export MASTER_PORT=$((15000 + SLURM_JOB_ID % 20000))
+
+echo "[preflight] NCCL smoke test..."
+srun --kill-on-bad-exit=1 uv run python @@repo_root/applications/dynacell/tools/nccl_smoke_test.py
+SMOKE_RC=$?
+if [ $SMOKE_RC -ne 0 ]; then
+    echo "[preflight] smoke test FAILED on $SLURM_JOB_NODELIST (rc=$SMOKE_RC); exiting before main srun" >&2
+    exit $SMOKE_RC
+fi
+
+# Lightning's SLURMEnvironment picks its own port from SLURM_JOB_ID; don't
+# leak the preflight values into the training srun.
+unset MASTER_ADDR MASTER_PORT
+```
+
+`exit $SMOKE_RC` fires the cleanup trap (unchanged from the current
+template), so `/tmp/$SLURM_JOB_ID` and `/dev/shm/$SLURM_JOB_ID` are cleaned
+up on preflight failure just like any other exit path.
+
+**Verify:** allocate an interactive session first so `SLURM_JOB_ID` is set
+(lets us derive `MASTER_PORT` the same way the template does — no
+hardcoded port):
+
+```sh
+salloc --nodes=1 --ntasks=4 --gpus=4 --time=00:10:00
+# inside the allocation:
+export MASTER_ADDR=$(hostname)
+export MASTER_PORT=$((15000 + SLURM_JOB_ID % 20000))
+srun uv run python /hpc/mydata/alex.kalinin/VisCy/applications/dynacell/tools/nccl_smoke_test.py
+```
+
+Should print `[nccl-smoke] OK world_size=4 sum=4.0` in <10 s. Without
+`MASTER_ADDR`/`MASTER_PORT`, `torch.distributed.init_process_group` with
+`init_method="env://"` (the default) will error out — the template exports
+them, so this manual command must too. The derive-from-`SLURM_JOB_ID` port
+formula matches the template exactly.
+
+---
+
+## Tests — expanded scope
+
+No existing test needs rewriting in v2.4. With Gap 2 deferred, the main
+dynacell `srun ...` line remains the last line of the rendered template
+(Gap 3's preflight srun is inserted *before* it), so
+`test_rendered_sbatch_has_srun_at_expected_resolved_path` keeps passing
+unchanged. `test_render_sbatch_directives_matches_dihan_order` is also
+unaffected (exclude only appears when set; default leaves leave it absent).
+
+New tests to add in
+`applications/dynacell/tests/test_submit_benchmark_job.py`:
+
+- `test_rendered_sbatch_has_preflight_srun_absolute_path` — preflight
+  `srun ...nccl_smoke_test.py` line references an absolute path rooted at
+  the repo (no bare `applications/...`).
+- `test_exclude_directive_rendered_when_set` — sbatch dict with
+  `exclude="gpu-d-1"` produces `#SBATCH --exclude=gpu-d-1`.
+- `test_exclude_directive_skipped_when_absent` — absent or `None` → no
+  `--exclude` substring.
+- `test_repo_root_substituted_in_preflight_path` — rendered preflight srun
+  contains the absolute repo-root path (assert starts with `/` and ends with
+  `/applications/dynacell/tools/nccl_smoke_test.py`).
+- `test_preflight_failure_exits_before_main_srun` — rendered template
+  contains `exit $SMOKE_RC` on the preflight-failure branch, ahead of the
+  main dynacell srun.
+
+---
+
+## Order of execution & risk
+
+1. **Gap 1 first, stand-alone commit.** Lowest risk. Unblocks today's
+   resubmits via `--override launcher.sbatch.exclude=...`. Tests: 2 new cases.
+2. **Gap 3 second** (smoke test file + template preflight wrapper + submitter
+   `repo_root` substitution). Moderate risk: template change, new Python
+   module. Verify: dry-render + diff rendered sbatch; run the smoke test on
+   a 4-GPU interactive allocation before enabling preflight for benchmark
+   submissions.
+3. **Gap 2 deferred.** Not shipped this round. See the Gap 2 section for the
+   full design; pick up later after a Slurm `requeuehold/update/release`
+   probe confirms the sequence works on our cluster.
+
+---
+
+## Out of scope
+
+- **Gap 2 (auto-requeue on NCCL watchdog hang) — deferred in v2.4.** Plan
+  preserved above for pickup after a Slurm `requeuehold/update/release`
+  probe. Gap 1 + Gap 3 together close the motivating GPU-hour loss (bad
+  nodes fail fast in preflight; operator resubmits with `--exclude`), so
+  Gap 2's incremental value is automation-only, not correctness.
+- Pattern divergence with
+  `applications/dynaclr/configs/training/slurm/train.sh` (the 4th gap from
+  the original review). Fix here stays dynacell-local; revisit
+  cross-application unification separately if the same NCCL-hang failure
+  mode appears in dynaclr runs.

+  `SLURM_JOB_NUM_NODES -eq 1` in the deferred Gap 2 design. Revisit when a
+  multi-node hardware profile lands.
+
+---
+
+## Appendix: Review findings addressed
+
+Plan stress-tested by 3 internal subagents (correctness, regression, merge
+compatibility) + external review. Changes from v1:
+
+### Blocking (addressed)
+
+- **Smoke-test script path was repo-relative.** v1 ran
+  `uv run python applications/dynacell/tools/nccl_smoke_test.py` under a
+  sbatch script that never `cd`'s. v2: inject `@@repo_root` substitution in
+  submitter; template uses absolute path.
+- **Smoke test missed `RANK`/`WORLD_SIZE`.** v1's `init_process_group` relied
+  on `env://` default but only exported `MASTER_ADDR`/`MASTER_PORT`. Slurm
+  sets `SLURM_PROCID`/`SLURM_NTASKS`, not `RANK`/`WORLD_SIZE`. v2: map in
+  Python via `os.environ.setdefault`.
+- **Existing test asserts the tail is a single srun line.** v1 only planned
+  `exclude` test additions. v2: explicit rewrite of
+  `test_rendered_sbatch_has_srun_at_expected_resolved_path` to content-based
+  assertion, plus 5 new tests for `--requeue`, preflight, requeue block,
+  exclude on/off, and repo-root substitution.
+
+### Important (addressed)
+
+- **`squeue -o %N` for multi-node jobs.** v2 guards on
+  `SLURM_JOB_NUM_NODES -eq 1` and uses `$SLURM_JOB_NODELIST` directly.
+- **`SLURM_RESTART_COUNT` unreliable on manual requeue.** v2 uses a
+  file-backed counter keyed on `SLURM_JOB_ID`.
+- **`scontrol update ExcNodeList` may be rejected on RUNNING jobs.** v2 uses
+  `requeuehold` → `update` → `release` sequence.
+- **Cleanup trap wipes `/dev/shm/$SLURM_JOB_ID` on manual requeue** (same
+  jobid reused → mmap cache lost). v2: `trap - EXIT` before `scontrol requeue`.
+- **Preflight failure writing synthetic marker into `$ERR_LOG`** races with
+  slurmstepd + pollutes user's error log. v2: separate `PREFLIGHT_MARKER`
+  file, Gap 2 checks both marker and stderr grep.
+- **`MASTER_PORT=29500` hardcoded.** v2: derive from `SLURM_JOB_ID` (same
+  pattern as Lightning's `SLURMEnvironment`).
+- **`MASTER_PORT` leaking to main srun** would override Lightning's
+  auto-picked port. v2: `unset MASTER_ADDR MASTER_PORT` after preflight.
+- **Variable ordering (Gap 2 vars referenced by Gap 3 preflight).** v2:
+  declare `ERR_LOG`/`PREFLIGHT_MARKER`/`COUNTER_FILE`/`BAD_LIST` in a shared
+  top-of-script block before both preflight and main srun.
+
+### Additional review pass (external, after v2 draft) → v2.1
+
+- **Requeue path was best-effort with unconditional `exit 0`.** Any failure
+  in the `scontrol requeuehold/update/release` trio would silently mask a
+  real failed training run as a green job, or requeue without the exclusion
+  actually applied. v2.1: chained `if scontrol ... && scontrol ... && scontrol
+  ... ; then exit 0 ; fi` — on any scontrol failure, fall through to
+  `exit $SRUN_RC` so the job stays visibly failed in Slurm accounting.
+- **Standalone smoke-test verify command was incomplete.** It relied on
+  `env://` init but didn't export `MASTER_ADDR`/`MASTER_PORT`, and used a
+  repo-relative script path. v2.1: verify command now exports both env vars
+  and invokes the script by absolute path, matching the rendered template.
+
+### Scope change → v2.4
+
+- **Gap 2 deferred.** User decision to ship Gap 1 + Gap 3 only this round.
+  Gap 2 section preserved intact (four rounds of review still valid for
+  future pickup), but marked `[DEFERRED]`.
+- **Gap 3 preflight simplified** from "touch marker and let Gap 2 handle it"
+  to fail-fast `exit $SMOKE_RC`. Cleanup trap handles tmp/shm on the exit
+  path — no leak.
+- **Shared-vars block dropped.** `ERR_LOG` / `BAD_LIST` / `COUNTER_FILE` /
+  `PREFLIGHT_MARKER` / `MAX_REQUEUE` only existed to serve the deferred
+  requeue decision block.
+- **`#SBATCH --requeue` dropped.** It was paired with Gap 2's manual requeue;
+  without that, it only covers Slurm-side NODE_FAIL / preempt, which is out
+  of the motivating scope (NCCL hangs don't trigger `--requeue`).
+- **Two planned tests dropped.** `test_rendered_sbatch_has_requeue_directive`
+  and `test_rendered_sbatch_has_requeue_block` — both exercised Gap 2
+  artifacts that no longer render.
+- **Existing test rewrite dropped.**
+  `test_rendered_sbatch_has_srun_at_expected_resolved_path` uses
+  `rendered.splitlines()[-1]`, which still works: Gap 3's preflight srun is
+  inserted *before* the main dynacell srun, so the dynacell srun remains the
+  last line of the rendered template.
+
+### Fourth external review pass → v2.3
+
+- **`#SBATCH --requeue` emission path was underspecified.** v2.2 said the
+  directive "flows through `@@sbatch_directives` substitution — handled at
+  render time", but `_render_sbatch_directives()` only emits keyed directives
+  from `_SBATCH_DIRECTIVE_ORDER` (key + value pairs) plus `--output`/`--error`
+  — there is no code path for a bare valueless directive. Implementing the
+  plan as written would have produced a rendered sbatch with no `--requeue`
+  line, silently disabling the Slurm-side auto-requeue Gap 2 depends on.
+  v2.3: `#SBATCH --requeue` is a literal line in `sbatch_template.sbatch`
+  directly after `@@sbatch_directives` (same pattern as `umask 0002`, `ml
+  uv`, cleanup trap — always-on scaffolding belongs in the template). No
+  submitter change; `_SBATCH_DIRECTIVE_ORDER` stays keyed-only. Test
+  `test_rendered_sbatch_has_requeue_directive` is unaffected (content-based).
+
+### Third external review pass → v2.2
+
+- **Held-pending leak on partial scontrol failure.** v2.1's `&&` chain
+  (`requeuehold && update && release`) short-circuits: if `requeuehold`
+  succeeds but `update` fails, `release` never runs and the job stays stuck
+  in held-pending. v2.2: explicit state machine — if `requeuehold` returns
+  0, always attempt `release` before exiting, even on subsequent failures;
+  warn the operator if `release` itself fails (manual recovery needed).
+  `REQUEUE_OK=1` gates the `exit 0` so a successful-hold-but-failed-update
+  path can't report green.
+- **Cleanup leaked on non-requeued failure path.** `trap - EXIT` was
+  disabled unconditionally before scontrol, so on any scontrol failure the
+  job exited `$SRUN_RC` without running cleanup, leaking
+  `/tmp/$SLURM_JOB_ID` and `/dev/shm/$SLURM_JOB_ID`. v2.2: call `cleanup`
+  explicitly before `exit $SRUN_RC` on the scontrol-failure branch. The
+  normal-failure branch (SHOULD_REQUEUE=0) still has the EXIT trap intact,
+  so cleanup runs there unchanged.
+- **Manual verify command hardcoded `MASTER_PORT=29500`.** v2.2: switched to
+  `salloc` + `export MASTER_PORT=$((15000 + SLURM_JOB_ID % 20000))`,
+  matching the template's per-job-id derivation. No fixed-port footguns.
+
+### Nitpicks (not adopted)
+
+- Gratuitous `set -e`/`set +e` toggles — v2 avoids them entirely by letting
+  the original un-errexit'd shell semantics hold. Strict error checking is
+  scoped only to the scontrol trio (v2.1), where it matters for correctness.
+- Grep regex brittleness for watchdog signature — current `"Watchdog caught
+  collective operation timeout"` is the stable c10d message; accept
+  brittleness to PyTorch upgrades (noisy upgrade will be caught by
+  preflight, not the post-hoc grep).
+- `BAD_LIST` collision across leaves — each leaf's `run_root` is unique;
+  scope by `$SLURM_JOB_ID` in the filename belt-and-suspenders.
+
+### Positive findings (no action)
+
+- No merge conflicts with `main` or other open PRs; all three files this
+  plan touches are only edited on `dynacell-models` and only by prior
+  commits, not in-flight work.
+- Hardware profile YAMLs don't need parallel edits — `exclude` flows through
+  `--override launcher.sbatch.exclude=...` without requiring a profile
+  change.

Subject: [PATCH 174/311] feat(dynacell): add --exclude as optional SBATCH
 directive
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Lets operators steer around bad nodes when a specific host is hanging
intra-node NCCL peer links. Usage:

    --override launcher.sbatch.exclude=gpu-d-1

Renders as bare ``#SBATCH --exclude=<hostlist>`` between ``--constraint``
and ``--output``. Handled the same way ``constraint`` is — optional, null
or absent value skips the line entirely — so existing leaves keep
rendering identically.

Closes Gap 1 from submit-reliability-plan.md. Gap 3 (NCCL preflight)
follows in a separate commit.

Subject: [PATCH 175/311] feat(dynacell): add NCCL preflight smoke test to
 sbatch template

Surface broken intra-node NCCL peer links in ~60 s via a small
all_reduce + barrier probe run under srun before the main training
step, instead of burning the full 30-minute PyTorch watchdog timeout
on the DDP initial-parameter broadcast (as happened to four sibling
FCMAE jobs on gpu-d-1 on 2026-04-21, each wasting ~1 h of H200 time).

On preflight failure, the script exits with the smoke test's rc; the
existing cleanup trap still fires, so /tmp/$SLURM_JOB_ID and
/dev/shm/$SLURM_JOB_ID are cleaned up on the failure path. The
operator then resubmits with ``--override launcher.sbatch.exclude=``
(Gap 1) to steer around the bad node.

Implementation notes:

- ``nccl_smoke_test.py`` maps Slurm's per-task env vars
  (SLURM_PROCID/SLURM_NTASKS/SLURM_LOCALID) to the env:// init vars
  torch.distributed expects (RANK/WORLD_SIZE/LOCAL_RANK), so the
  template only needs to export MASTER_ADDR/MASTER_PORT.
- MASTER_PORT is derived from SLURM_JOB_ID
  (``15000 + SLURM_JOB_ID % 20000``) to avoid per-host collisions,
  matching Lightning's SLURMEnvironment strategy. Both vars are
  ``unset`` before the main dynacell srun so Lightning's environment
  can pick its own without inheriting the preflight values.
- ``repo_root`` is injected into the template substitution so the
  rendered sbatch invokes the smoke test by absolute path (sbatch
  scripts run from arbitrary CWDs with no ``cd``).

Closes Gap 3 from submit-reliability-plan.md. Gap 2 (auto-requeue)
remains deferred.

Subject: [PATCH 176/311] feat(viscy-data): add include/exclude_fov_names to
 HCSDataModule

Plate-level FOV filters applied before the train/val split so a single
zarr can contribute a subset of positions to training without the held-
out FOVs leaking in. Motivating case: the A549 Mantis infection dataset
keeps 27 positions as a dedicated test split inside the same plate used
for training. Tests cover include, exclude, empty-result error, and
mutual exclusion with mmap_preload (which would require also filtering
the preload buffer; left for a later pass).

Subject: [PATCH 177/311] feat(cytoland): add A549 infection VSCyto3D
 warm-start finetune configs

Multi-microscope finetune covering A549 from Hummingbird (D1, D2) and
Mantis (D3) to improve tracking of infected cells, where the current
VSCyto3D sometimes hallucinates replication sites as nuclei. Each sub-
DataModule keeps its native channel names (DAPI_Density3D /
TXR_Density3D on D1/D2; raw mCherry / raw Cy5 on D3) and uses per-
timepoint normalization; CombinedDataModule(MAX_SIZE_CYCLE) pulls one
sub-batch per step so every microscope contributes equally to each
gradient step regardless of pool size. D3 excludes the 27 Mantis FOVs
held out as the segmentation test set.

Warm-start from the hek-a549-ipsc-finetune VSCyto3D last.ckpt; bf16-
mixed on 4 GPUs; 50 epochs; MixedLoss (L1 + MS-DSSIM) matching the
existing vscyto3d/finetune.yml recipe.

Includes a preprocess shell script for D3 (the only dataset missing
normalization_metadata) so the exact invocation is reproducible.

Data summary: 2026-02 Viral infection wiki page (MUG space).

Subject: [PATCH 178/311] refactor(dynacell): /simplify cleanup of preflight +
 exclude impl

Post-review cleanup of the NCCL preflight + --exclude SBATCH changes,
driven by /simplify findings:

- Drop ``os.environ.setdefault`` in ``nccl_smoke_test.py`` in favor of
  direct assignment so a missing Slurm per-task env var raises KeyError
  immediately instead of letting NCCL init fail with a cryptic error
  later ("prefer raising errors" per CLAUDE.md).
- Rewrite ``nccl_smoke_test.main`` docstring to state the contract
  (returns 0 on success; raises on hang or NCCL error) instead of
  narrating the all_reduce/barrier steps.
- Hoist ``repo_root`` out of ``submit()`` into module-level ``_REPO_ROOT``
  so ``.resolve()`` runs once at import, not on every call.
- Introduce a module-scoped ``rendered_celldiff_sbatch`` fixture so the
  three preflight tests share one rendered sbatch instead of each
  invoking ``submit()`` from scratch. Needs a local ``pytest.MonkeyPatch``
  to set ``DYNACELL_MANIFEST_ROOTS`` because module-scoped fixtures run
  before conftest's function-scoped autouse monkeypatch.

All 16 tests in ``test_submit_benchmark_job.py`` pass.

Subject: [PATCH 179/311] perf(viscy-data): store FOV filters as sets for O(1)
 lookup

Defensive change against callers that supply large filter lists; at the
current D3 scale (243 positions, 27-entry exclude) the difference is
negligible. Loosens the parameter type to ``Iterable[str]`` since any
iterable of names is now acceptable.

 before transforms

NormalizeSampled(level="timepoint_statistics") was unusable: the
dataset passed through the zattrs layout {tp_idx: {stat: Tensor}},
but the transform expects the level value to be a flat {stat: Tensor}
and would KeyError on the first sample.

SlidingWindowDataset now picks the current sample's timepoint entry
before attaching norm_meta, honoring the contract already documented
in NormalizeSampled's docstring. Adds a unit test for the helper and
an integration test that routes NormalizeSampled(level=
"timepoint_statistics") through SlidingWindowDataset on a two-
timepoint fixture to guard against regression.

Subject: [PATCH 181/311] feat(dynacell): add FNet3D paper predict configs for
 ipsc_confocal

Mirrors the existing unetvit3d predict leaves so FNet3D paper-baseline
checkpoints can be benchmarked against ipsc_confocal test_cropped stores
via the same submit_benchmark_job flow. Each leaf pins its best val-loss
checkpoint and targets a distinct output zarr.

Subject: [PATCH 182/311] feat(cytoland): align A549 infection finetune to
 dynacell FCMAE recipe
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adopts the proven dynacell FCMAE-VSCyto3D augmentation and optimizer
schema for the A549 infected-cell finetune: CPU RandWeightedCropd
(num_samples=4, spatial_size=[20,600,600]) biases crops to nucleus-dense
regions, and the full 6-step GPU aug stack (affine + center crop +
contrast/intensity/noise/smooth) replaces the earlier single
BatchedRandSpatialCropd. Bumps z_window_size to 20 so the affine has
Z headroom. Sets strategy=ddp_find_unused_parameters_true, which is
required for FullyConvolutionalMAE(pretraining=False) under DDP —
default strategy errors at step 1 because decoder params have no
gradients on some forward paths.

Keeps four deliberate cytoland-specific divergences:
  - full-ckpt warm-start from the published VSCyto3D (epoch=83) rather
    than dynacell's encoder-only fcmae.ckpt init — leverages the
    supervised training already in that checkpoint;
  - out_channels=2 for the dual H2B/CAAX target (vs. dynacell's
    per-organelle single-target benchmarks);
  - timepoint_statistics normalization to track infection-progression
    signal drift that fov/dataset stats would blur out;
  - lr=2e-4 matching vs_test/finetune_3d.py canonical (dynacell's 4e-4
    is a retune vs. UNeXt2 throughput, not the right anchor here).

max_epochs=100 matches the vs_test budget that produced the published
ckpt. ckpt_path now points at the authoritative
fcmae-cyto3d-sensor source rather than the viscy-0.1.0 symlink.

Adds finetune_a549_infected_d2_smoke.yml (single-GPU, tiny batch,
limited steps) for pipeline validation before launch, and
run_a549_infected.slurm for the 4xH200 5-day job.

Subject: [PATCH 183/311] feat(dynacell): add first Stage 7 joint train leaf
 (celldiff, ER/SEC61B)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

First joint train leaf per A549_EXPANSION_ROADMAP.md Stage 7. Uses
BatchedConcatDataModule wrapping two explicit HCSDataModule children —
ipsc_confocal SEC61B train + a549_mantis_2024_11_07 SEC61B train (first
of 7 per-plate stores from dynacell-paper PR A1).

Joint leaves bypass the single-dataset resolver (no benchmark.dataset_ref)
and author the data block inline because hparams live on each child.
Shared HCS init_args factor via a YAML merge anchor so only data_path
differs between the two children. Topology overridden to DDP 4-GPU —
exercising the ShardedDistributedSampler path landed in viscy-data
4bc2e53, which is the whole point of the joint loader.

The composition test pins class_path, 2-child count, child ordering and
paths, shared transform/hparam identity, 4-GPU DDP topology, bf16
precision, the SLURM ntasks/devices/gpus invariant, and the absence of
dataset_ref. 100 composition tests pass.

Subject: [PATCH 184/311] feat(viscy-data): support include/exclude_fov_names
 with mmap_preload (#411)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(cytoland): use --ntasks-per-node in A549 slurm, document the gotcha

Lightning's SLURMEnvironment._validate_srun_variables rejects
SLURM_NTASKS at trainer init with a RuntimeError hinting at
--ntasks-per-node. The A549 infection slurm launcher used --ntasks=4,
which would have killed the 4xH200 job ~seconds into its 5-day
allocation. Caught in a 2-GPU DDP smoke before launch.

Adds a SLURM-for-Lightning-DDP note to the root CLAUDE.md so this
doesn't bite the next hand-written .slurm. Dynacell's
submit_benchmark_job.py already emits --ntasks-per-node correctly; the
note is for scripts that don't go through that launcher.

* feat(viscy-data): support include/exclude_fov_names with mmap_preload

Previously HCSDataModule raised ValueError when a caller combined
include_fov_names or exclude_fov_names with mmap_preload=True. The
underlying reason was a real layout mismatch: prepare_data() wrote the
mmap buffer in plate-iteration order over ALL positions, while
_setup_fit built its orig_positions from the filtered list — the two
index spaces didn't align, so filtered index i aliased the wrong FOV
in the mmap buffer.

This blocks mmap_preload on any dataset that uses filters to hold out
a test split, which is the common case for large training stores that
stand to gain the most from local-scratch caching.

Fix is minimal: honor _keep_position in prepare_data() so the mmap
buffer is built over exactly the positions _setup_fit will iterate,
and extend _mmap_cache_dir's fingerprint to include the sorted
include/exclude sets so runs with different filter specs cannot
accidentally share a cache (they would alias the wrong FOVs).

Replaces the reject test with two positive tests: a roundtrip that
asserts filtered FOVs are what the mmap-backed dataloader serves, and
a fingerprint check that no-filter / include / exclude configs map to
distinct cache dirs.

* refactor(viscy-data): extract _filtered_positions helper in HCSDataModule

Both prepare_data() and _setup_fit() now apply include/exclude_fov_names
via a shared _filtered_positions(plate) method. Removes the duplicated
comprehension + empty-plate ValueError that each site carried, and
guarantees the two index spaces (mmap buffer layout and fit-time
orig_positions) stay aligned when the filter logic evolves.

No behavior change.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* refactor(viscy-data): annotate _filtered_positions plate parameter

Other methods in hcs.py and sibling modules (select.py, cell_classification.py,
segmentation.py, mmap_cache.py) all type plate arguments as `Plate` from
iohub.ngff. Match that convention.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat(dynacell): add joint train leaf smoke tool

CPU-only smoke that composes a joint leaf, instantiates the datamodule
end-to-end via jsonargparse (recurses into data_modules + transform
lists the way LightningCLI does at runtime), opens the real zarrs, and
iterates a handful of train + val batches to confirm the full
loader/transform wiring holds.

Sits next to nccl_smoke_test.py as a preflight tool. Default
invocation smokes the celldiff ER joint leaf with a 12-FOV subsampled
SEC61B_test12.zarr override for fast startup; --leaf covers future
joint leaves, --no-ipsc-override exercises the full-size zarr.

Scope is explicit: no GPU augmentations (those fire in
on_after_batch_transfer and need a GPU). For a full end-to-end smoke
including GPU transforms + forward + backward, use
`dynacell fit -c <leaf> --trainer.fast_dev_run=5` on a GPU node.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat(viscy-data): scope mmap_preload to fit/validate and harden cache checks

Lightning calls `prepare_data` stage-agnostically, so PR #411's filter
enforcement in `prepare_data` was newly reachable from predict/test
runs — hard-failing on empty-match filters and wasting I/O building
caches that `_setup_predict`/`_setup_test` never consume. Lock in the
contract that `mmap_preload` is fit/validate-only and that
`include/exclude_fov_names` are filters only for fit/validate; predict
and test use all plate positions and skip the mmap path.

Also replace three opaque `_setup_fit` failure modes (tensordict
missing, cache not ready, cache corrupted) with actionable errors so
manual `setup('fit')` without a prior `prepare_data()` fails loudly
at the source instead of inside `MemoryMappedTensor.from_filename`.

+### SLURM scripts for Lightning DDP jobs
+
+When hand-writing `.slurm` scripts that launch Lightning via `srun`, always use `--ntasks-per-node=N` (not `--ntasks=N`). Lightning's `SLURMEnvironment` validates `SLURM_NTASKS_PER_NODE` at trainer init and raises `RuntimeError: You set --ntasks=N in your SLURM bash script, but this variable is not supported. HINT: Use --ntasks-per-node=N instead.` — the job then dies seconds into the allocation.
+
+Invariant: `#SBATCH --ntasks-per-node=N` must equal `trainer.devices` in the YAML config and `#SBATCH --gpus=N` (single-node) or `#SBATCH --gpus-per-node=N` (multi-node).
+
+The dynacell launcher (`applications/dynacell/tools/submit_benchmark_job.py`) already emits `--ntasks-per-node` correctly; this note is for hand-written scripts (e.g., `applications/cytoland/examples/configs/*/run_*.slurm`).

+r"""CPU-only smoke for BatchedConcatDataModule joint train leaves.
+
+Composes the leaf, instantiates the datamodule end-to-end via
+``jsonargparse`` (matches LightningCLI's recursive type-driven
+instantiation), opens the real zarrs, and iterates a handful of train
+and val batches to confirm the loader/transform wiring holds.
+
+The GPU augmentation pipeline runs in ``on_after_batch_transfer`` and
+needs an actual GPU — this smoke explicitly does not cover it. For a
+full end-to-end smoke including GPU transforms + forward + backward,
+use ``uv run dynacell fit -c <leaf> --trainer.fast_dev_run=5`` on a
+GPU node (disables checkpointing and loggers; 5 train + 5 val batches).

Subject: [PATCH 185/311] docs(dynacell): refresh virtual_staining README for
 fit-split + joint leaves

Two structural changes have landed in the virtual_staining/ benchmark
config tree that the README didn't yet describe.

The fit-overlay split (5950576) introduced a separate
_internal/shared/model/data_overlays/<model>_fit.yml sibling to
model_overlays/<model>_fit.yml, so the layout block now shows both
directories and their roles. Single-store train leaves compose both
halves; the explanation is folded into the train-leaf base-chain
example.

The first joint train leaf (9654e2b) established the multi-dataset
fit pattern: joint leaves use viscy_data.BatchedConcatDataModule with
explicit child viscy_data.HCSDataModule blocks, compose only the
model_overlays/ half, and author the data: block inline. The README
now calls out the single-store vs joint composition as two distinct
patterns and points readers at MULTI_DATASET_TRAINING_RECOMMENDATION.md
for the design rationale.

The ValueError thrown when seg_model is None at the nucleus/membrane

failure points the caller at the right argument and the right type.

Subject: [PATCH 187/311] fix(dynacell): guard sbatch cleanup against unset
 SLURM_JOB_ID

The cleanup trap previously expanded to `rm -rf /tmp/$SLURM_JOB_ID
/dev/shm/$SLURM_JOB_ID` with no safeguard. If the script ever runs
outside Slurm (manual smoke, edited copy, mistakenly-sourced template),
SLURM_JOB_ID is unset and the command degenerates into
`rm -rf /tmp/ /dev/shm/`, wiping shared temp locations on whichever
node it ran on.

Wrap the cleanup in `[[ -n "${SLURM_JOB_ID:-}" ]]` and quote the
expansions so a missing job id becomes a no-op instead of a
catastrophe.

Subject: [PATCH 188/311] fix(dynacell): single-source dinov3 model name via
 Hydra group
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

eval.yaml selected ``feature_extractor/dinov3: lvd1689m`` via Hydra
defaults and then overrode ``feature_extractor.dinov3.pretrained_model_name``
inline with a different identifier (ConvNext-Base vs the group's
ViT-L/16). The inline override silently won at runtime, making the
group selector cosmetic — confusing for reproducibility because the
group name suggests it controls the model.

Promote the runtime canonical (ConvNext-Base) to the group file and
drop the inline override so the Hydra group selector is the single
source of truth for the DINOv3 backbone choice.

Subject: [PATCH 189/311] fix(dynacell): drop NaN bars from cross-model metric
 figure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In the cross-model bar chart, ``stats["mean"].reindex(plot_metrics)``
produces NaN entries for any metric a given model did not report.
Passing those NaNs through ``ax.bar(..., yerr=stds.values, ...)``
yields version-dependent matplotlib behavior — recent versions raise
or warn on NaN yerr, older ones quietly draw a zero-height error
bar.

Mask each model's missing metrics before plotting: skip the model
entirely when no metrics are present, otherwise drop the NaN bars
and ``fillna(0)`` on the surviving stds so yerr stays finite.

Subject: [PATCH 190/311] refactor(dynacell): use Field(default_factory=list)
 for Pydantic list defaults

Replace bare ``list[T] = []`` defaults on Pydantic ``BaseModel`` fields
with ``Field(default_factory=list)`` in ``BenchmarkSpec``,
``Provenance``, and ``CollectionExperiment``. Pydantic v2 deep-copies
mutable defaults per-instance so the bare form is not actually a
shared-state bug, but the factory form matches the convention already
used in ``viscy_utils.evaluation.linear_classifier_config`` and is the
explicit-intent style most readers expect for list defaults.

Subject: [PATCH 191/311] fix(viscy-utils): strip top-level _-prefixed keys
 from composed config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

YAML merge anchors must be defined at top level (the only scope
``yaml.safe_load`` resolves), but the defining key survives parse and
gets passed through to consumers. LightningCLI / jsonargparse reject
unknown top-level keys, so a leaf that uses ``_hcs_init_args: &hcs_init_args``
to factor shared init_args across joint-datamodule children fails at
``dynacell fit`` with::

    Subcommand 'fit' does not accept option '_hcs_init_args.augmentations'

This pattern slipped past the CPU-only smoke (which feeds the ``data:``
block straight into jsonargparse and never sees the top-level keys),
so the only place it would have surfaced is the actual SLURM run.

Establish the convention that top-level keys starting with ``_`` are
private to the YAML composition layer and are stripped before the
returned dict is handed to LightningCLI. The strip applies at every
recursion level so anchor defs in ``base:`` fragments don't leak
through ``deep_merge`` either. Resolvers still see the full dict —
strip is the final step before return.

Subject: [PATCH 192/311] docs(dynacell): document anchor convention; pin
 no-anchor-leak invariant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The first joint train leaf relies on a top-level ``_hcs_init_args:``
YAML merge anchor to factor shared init_args across the two child
HCSDataModule blocks. Now that ``load_composed_config`` strips
underscore-prefixed top-level keys before returning, the leaf is
LightningCLI-safe — but the convention only matters if leaf authors
know about it.

- Annotate the leaf's anchor block with a one-paragraph note pointing
  at the strip behavior and explaining why the prefix is required.
- Pin the invariant in ``test_joint_train_leaf_composes``: assert no
  top-level key starting with ``_`` leaks through composition. Without
  this guard, a regression in ``load_composed_config`` would make the
  joint leaf fail at SLURM-run time, the same gap that allowed this
  bug to ship in the first place.

Subject: [PATCH 193/311] chore(dynacell): declare wandb optional extra;
 document the runtime gap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The default `trainer.logger` in `configs/recipes/trainer/fit.yml` is
`lightning.pytorch.loggers.WandbLogger`, but `applications/dynacell`
depends on `viscy-utils` (not `viscy-utils[eval]`) and `wandb` is in
viscy-utils' eval extra — so a vanilla `pip install dynacell` ships
without wandb. jsonargparse then rejects every fit/predict leaf at
schema validation time with `Requirement 'wandb>=0.12.10' not met`,
before `fast_dev_run` (or any other runtime mechanism) gets a chance
to disable the logger.

Add a `dynacell[wandb]` extra so consumers (dynacell-paper, end
users) can pin the runtime expectation cleanly. Document the gap in
the virtual_staining README's "Running" section: install via the
extra, or override `trainer.logger.class_path` to a non-W&B logger
like `CSVLogger`. No behavior change — the dep declaration just
catches up with what the recipes already require at runtime.

Subject: [PATCH 194/311] feat(dynacell): add canonical joint smoke leaf for
 celldiff/joint_ipsc_confocal_a549_mantis

`submit_benchmark_job.py`'s dotlist override parser cannot index into
list elements, so a smoke variant of a joint leaf cannot be made by
overriding a single child's `data_path` at submit time. Adds a
`train_smoke.yml` sibling next to the production `train.yml`: pre-swaps
the iPSC child to `SEC61B_test48.zarr` (48 FOVs, smoke-staging budget),
keeps the a549 child untouched (its train split is already 4 FOVs), and
swaps `hardware_4gpu` for `hardware_h200_single` so a single-GPU smoke
node can run it without DDP.

The leaf comment header documents the diff against `train.yml` and
points consumers at `--override trainer.fast_dev_run=true` (or
`trainer.max_steps=N`) for bounding wall time. README "Joint smoke
sibling" section explains why this is a sibling leaf rather than a
submit-time override. New `test_joint_train_smoke_leaf_composes` brackets
single-GPU topology, both children's zarr paths, and the no-anchor-leak
invariant.

Subject: [PATCH 195/311] feat(dynacell): add hardware_h200_single_smoke
 launcher profile

Adds a smoke-sized variant of hardware_h200_single that bounds
launcher.sbatch.time to 30 min. Identical otherwise (single H200,
ntasks_per_node=1, 256G mem). Re-points train_smoke.yml at the new
profile so a smoke job cannot sit on a multi-day allocation by
default. Pair with --override trainer.fast_dev_run=true (or
trainer.max_steps=N) so the run actually exits inside the wall.

test_joint_train_smoke_leaf_composes now asserts sbatch.time matches
the smoke value, locking the invariant into the leaf.

Subject: [PATCH 196/311] refactor(dynacell): /simplify smoke profile via
 wall-only overlay
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces the duplicated `hardware_h200_single_smoke.yml` (which copied
8 of 9 fields from `hardware_h200_single.yml`) with a 4-line
`wall_smoke.yml` that only overrides `launcher.sbatch.time`. The smoke
leaf now stacks `hardware_h200_single + wall_smoke + runtime_shared`,
matching the existing compose-by-overlay idiom. Future hardware tweaks
(cpus, mem, constraint) propagate to smoke automatically; future
hardware variants reuse `wall_smoke.yml` for free.

Also trims the smoke leaf header: drops the numbered "Differences from
sibling train.yml" enumeration (would rot the moment either leaf
changes; the README's "Joint smoke sibling" section already documents
the contract) and shortens the anchor-mechanism comment to a one-line
cross-ref into train.yml.

No behavior change — composed `launcher.sbatch` is byte-identical to
the previous form (verified by `test_joint_train_smoke_leaf_composes`,
which still asserts `time == "00:30:00"` and `constraint == "h200"`).

Subject: [PATCH 197/311] feat(dynacell): disable logger at the smoke leaf
 level

Consumers of train_smoke.yml shouldn't have to remember
`--override trainer.logger=false` at submit time, and smokes don't
need a logger by definition. Sets `trainer.logger: false` directly in
the leaf so future smokes for other models/organelles inherit the
same disable when the recipe defaults a WandbLogger.

Recipe `fit.yml` also defaults a `LearningRateMonitor` callback that
raises `MisconfigurationException` when `trainer.loggers` is empty
(`lr_monitor.py:121-122`), so the smoke leaf's `callbacks` list is
trimmed to just `ModelCheckpoint`. Lists replace wholesale under
deep_merge, so this cleanly drops LRMonitor without affecting prod.

`test_joint_train_smoke_leaf_composes` now asserts both invariants:
`trainer.logger is False` and LRMonitor is not in the callbacks list.

Subject: [PATCH 198/311] fix(viscy-data): drop non-tensor metadata in
 BatchedConcatDataModule combine
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`BatchedConcatDataModule.on_after_batch_transfer` combined per-key
values across micro-batches by assuming each value was either a list
(extend) or a tensor (`torch.cat`). HCSDataModule emits `norm_meta`
(dict of per-channel normalization stats, when
`load_normalization_metadata=True`, the default) and `index` (tuple
of `(img_name, t_idx, z_idx)`) per sample. After collation those keys
hit the cat branch and `torch.cat([dict_a, dict_b])` raised
`TypeError: expected Tensor as element 0 in argument 0, but got dict`,
killing joint training during Lightning's `_run_sanity_check`.

Joint training across heterogeneous children has no well-defined
combined semantic for these keys — channels need not align between
zarrs and FOV identifiers are dataset-specific — and Lightning's
training/validation only reads source/target tensors. Skip the key
during combine instead.

Existing tests (`test_batched_concat_datamodule_with_hcs_children`
and the DDP variants) iterate `next(iter(loader))` to inspect the
micro-batch contract but never invoke `on_after_batch_transfer`, so
the bug never surfaced. New regression test calls
`on_after_batch_transfer` against the real HCS fixture (which does
write per-FOV normalization metadata) and asserts tensor keys
concatenate cleanly while dict-valued metadata is dropped.

Subject: [PATCH 199/311] fix(dynacell): cut smoke leaf batch_size to 1 to fit
 a single H200
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

train.yml's batch_size=4 across 4 GPUs OOM'd when run on a single H200
(per-step memory is batch_size * num_samples patches at [8, 512, 512]).
Drops the smoke's child batch_size to 1 so per-step VRAM stays inside
one GPU's budget while the patch shape stays identical to train.yml —
the validation remains apples-to-apples.

`RandWeightedCropd.num_samples` also drops from 2 to 1: HCSDataModule
requires `batch_size % num_samples == 0` and rejects the leaf at
schema-validation time otherwise. num_samples=1 is the largest value
that satisfies the constraint with batch_size=1.

`test_joint_train_smoke_leaf_composes` follows along (asserts
batch_size=1 instead of 4).

Subject: [PATCH 200/311] feat(dynacell): add 4-GPU DDP smoke leaf for joint
 celldiff SEC61B

Sibling of train_smoke.yml that swaps hardware_h200_single -> hardware_4gpu
and adds trainer.strategy=ddp, devices=4, max_steps=5. Validates that
BatchedConcatDataModule + ShardedDistributedSampler integrate correctly
on the production DDP topology - single-GPU smoke already proved the
joint loader and training/val loops work; this isolates sharding.

batch_size=1 / num_samples=1 kept identical to train_smoke.yml so the
per-rank memory profile is the proven one - sharding is the only new
variable. max_steps=5 baked in (not override) after train_smoke.yml
TIMEOUT'd at 30 min from a missed --override at submit time.

+# 4-GPU DDP smoke variant of train.yml — small zarrs, 4 H200s, 30-min wall.
+#
+# Purpose: validate `BatchedConcatDataModule` + `ShardedDistributedSampler`
+# integration on the real DDP topology used in production. The single-GPU
+# `train_smoke.yml` already proved the joint loader and training/val loops
+# work end-to-end; this leaf isolates the *sharding* behavior — that each
+# rank pulls a disjoint slice of the joint dataset and the sampler attaches
+# automatically once `torch.distributed` is initialized.
+#
+# Why a sibling leaf rather than --override on train.yml: train.yml points
+# at the full 423-FOV iPSC SEC61B store, which `mmap_preload` stages to
+# /dev/shm in 45+ min — blows the 30-min smoke wall before the first step.
+# We swap the iPSC data_path to its `_test48` companion (48 FOVs, ~24 GB)
+# so staging finishes in under a minute. submit_benchmark_job.py's --override
+# parser cannot index into list elements (`data_modules.0` / `data_modules[0]`
+# both fail), so pre-swapping in a sibling leaf is the supported fix — same
+# rationale as train_smoke.yml.
+#
+# Why batch_size=1 / num_samples=1: matches train_smoke.yml. The point of
+# this smoke is "does the sampler shard the joint dataset across ranks",
+# not "does train.yml's heavier per-rank hparams (batch=4, num_samples=2)
+# fit on H200". Validating sharding at small batch isolates the question;
+# memory tuning is a follow-up smoke if needed.
+#
+# Why max_steps is baked in (not --override): the wall_smoke.yml docstring
+# explicitly says to bound the run, and we just spent a 30-min wall on
+# train_smoke.yml because we forgot the override at submit time. Bake it

Subject: [PATCH 201/311] perf(viscy-utils): bf16-precision SSIM helper for
 Hopper FCMAE training (#412)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(viscy-utils): add bf16-precision SSIM helper

Replaces monai.metrics.regression.compute_ssim_and_cs (which
unconditionally casts both inputs to fp32 internally) with a precision-
aware variant in viscy_utils.evaluation.metrics. The helper runs the 5
Gaussian-mean convolutions in bf16 and promotes only the variance
subtractions and C1/C2-guarded divisions to fp32. Squared products are
computed in fp32 first, then cast to bf16 for the conv input, which
preserves precision on the precision-sensitive squaring step.

Why: FCMAE VSCyto3D training on Hopper (H100/H200) runs at ~45 s/step
vs ~3-5 s/step on Ampere/Ada because monai's 25 fp32 conv ops per loss
invocation can't use Hopper's bf16 tensor cores. The bf16 helper
restores tensor-core path while keeping the precision-sensitive math in
fp32 to match monai's NaN-resistance properties.

Numerical contract validated by 7 tests in test_metrics.py:
- per-pixel random: rtol=5e-2, atol=1e-1 (>=2x margin over measured
  0.0418 max abs drift)
- aggregate random: rtol=1e-2, atol=1e-2 (>=25% margin over measured
  0.00776)
- aggregate correlated-pair (pred=target+0.05*randn): rtol=2e-3,
  atol=5e-3
- gradient flow: cosine-similarity >= 0.99 between helper and monai-ref
  flat gradients; sign-flip fraction < 1% on |grad_ref| > 1e-3 voxels
- dtype invariance: helper returns fp32 regardless of fp32/bf16/fp16
  input dtype

The decorators on MixedLoss/SpotlightLoss are addressed in a follow-up
commit; this commit only changes the SSIM compute path.

* refactor(viscy-utils): drop redundant fp32 cast on MixedLoss/SpotlightLoss

Removes @torch.amp.custom_fwd(device_type="cuda",
cast_inputs=torch.float32) from MixedLoss.forward and SpotlightLoss.forward.

For MixedLoss: the decorator was redundant because monai's
compute_ssim_and_cs already cast both SSIM inputs to fp32 internally
(monai/metrics/regression.py:402-403), so the outer @custom_fwd only
affected F.l1_loss / F.mse_loss / outer F.avg_pool3d — none of which
are the slow path. Now that the SSIM compute path goes through
_compute_ssim_and_cs_bf16 (preceding commit) the fp32 island the
decorator created actively defeats the purpose. The L1 and MSE branches
remain numerically identical because PyTorch's autocast policy already
promotes them to fp32 (cf. test_mixed_loss_l1_only_matches_torch_l1).

For SpotlightLoss: the decorator's fp32 island was layered onto a
function with no conv-heavy ops — only squared error, masking, sums,
and divisions, all of which are in autocast's promote-to-fp32 list
already. Removal is a no-op for behaviour but unblocks autocast
plumbing for future precision experiments.

New tests:
- test_mixed_loss.py (4): forward outside autocast, forward under bf16
  autocast (drift vs explicit-fp32 baseline within rtol=1e-2, atol=1e-2),
  gradient flow under autocast, L1-only bit-exact F.l1_loss.
- test_spotlight_loss.py (+2): autocast bf16 forward+backward finite,
  autocast result matches explicit-fp32 baseline within rtol=1e-2,
  atol=1e-2.

* docs(dynacell): record Hopper FCMAE slowdown investigation + bf16 fix

Captures the full diagnostic chain from "Hopper trains 10-15x slower
than Ampere/Ada" to "fp32 MS-DSSIM is the dominant slow term" to the
landed bf16 SSIM helper, with measured numbers for every claim.

Notable artefacts the doc records (so future readers don't redo the
work):

- T2 probe (job 31452082) showed compute_ms collapses from 45.5 s/step
  to ~0.9 s/step on identical N=4 H100 hardware when MS-DSSIM is
  removed.
- monai's compute_ssim_and_cs unconditionally casts both inputs to fp32
  at regression.py:402-403; the @torch.amp.custom_fwd decorator on
  MixedLoss/SpotlightLoss was layered redundantly on top.
- T6 probe (job 31453564) with the bf16 helper measured 4151 ms/step
  steady-state mean (6 consecutive STEP_TIMER lines) on identical
  N=4 H100 — 10.97x speedup, fix landed in commits e42c49a and
  3a7fa05.

Falsified hypotheses that were time-consuming to evaluate are also
recorded (cuDNN [240,960,1,1] stride mismatch, DDP bucket-view
mismatch, Lightning vs synthetic data, sync_batchnorm, MS-DSSIM-only
symmetric probe T4 cancelled due to 8h queue slip) so the next person
investigating Hopper performance regressions doesn't re-run them.

* test(viscy-utils): tighten gradient sign-flip + spotlight autocast bounds

Two findings from /verify-plan:

1. test_ssim_helper_gradient_flow used |grad_ref| > 1e-3 to mask
   non-tiny voxels for the sign-flip-fraction assertion, but the
   measured |grad_ref| max is ~1.7e-6 — so the predicate selected zero
   voxels and the assertion was vacuous. Switch to a relative threshold
   (10% of the reference grad max) so the assertion is scale-invariant
   and meaningful regardless of the loss scale.

2. test_spotlight_loss_autocast_matches_fp32_baseline used rtol=1e-2,
   atol=1e-2 but measured drift is 0.0 — SpotlightLoss has no
   conv-heavy ops and autocast policy promotes the precision-sensitive
   pieces to fp32 anyway. Tighten to rtol=1e-3, atol=1e-3 to match the
   plan's spec and catch any future drift.

Cosine-similarity check (>= 0.99 between flat helper-grad and flat
reference-grad) was already meaningful and unchanged.

* refactor(viscy-utils): specialize bf16 SSIM helper to 3D, drop redundant tensors

Two simplify passes consolidated:

1. Drop the ``spatial_dims`` parameter and the ``conv_fn = getattr(F,
   f"conv{spatial_dims}d")`` indirection. The helper is already
   specialized to "uniform kernel only" per the original plan; the only
   caller (``ssim_25d``) only ever passes ``spatial_dims=3``. Hardcoding
   ``F.conv3d`` directly removes a parameter from the public surface and
   removes a getattr lookup per conv call. Docstring updated to spell out
   the 3D specialization.

2. Drop the explicit ``y_pred_bf`` and ``y_bf`` intermediate tensors. The
   bf16 versions of the simple (non-squared) inputs are only consumed
   once each (in ``mu_x`` / ``mu_y`` convs), so caching them as named
   variables is pure memory duplication — peak working-set tensors drop
   from 7 to 5. Inline the cast at the conv site so the temporary lives
   only during the conv. Squared-product bf16 tensors stay named because
   the squaring must happen in fp32 first to preserve precision and the
   result is genuinely a different tensor.

Test wrapper ``_bf16(...)`` updated to drop the ``spatial_dims=3``
kwarg; ``_SPATIAL_DIMS`` module constant removed; ``_ref(...)`` keeps
``spatial_dims=3`` since monai's signature still requires it.

All 34 tests still pass; numerical contract unchanged.

* chore(viscy-utils): apply PR review nits to bf16 SSIM helper

Three small improvements from PR #412 review:

1. metrics.py:178 — switch ``data_range: Union[float, torch.Tensor]``
   to ``data_range: float | torch.Tensor`` (modern typing per global
   CLAUDE.md). The pre-existing ``Union[...]`` at line 270 in
   ``ssim_25d`` is left alone per surgical-changes rule; the import
   stays since it's still used.

2. metrics.py:233 — add a brief comment explaining why the kernel is
   rebuilt per call (small tensor, negligible per-step cost relative
   to the conv) and what the cache-key would be if profiling ever
   shows it matters. Pre-empts the "should we cache this?" question
   future readers will have.

3. test_metrics.py:108 — update the gradient-flow test docstring to
   reference the relative threshold (10% of grad max) that the code
   actually uses; it previously said ``|grad_ref| > 1e-3`` which was
   the absolute threshold from before commit a498d59.

* chore(viscy-utils): address Copilot review on PR #412

Four of Copilot's six findings applied; one rejected.

Applied:
- ``test_metrics.py``: monai is not a hard dep of viscy-utils (only
  transitively pulled via viscy-models / optimizers.py). Use
  ``pytest.importorskip("monai.metrics.regression")`` so the suite
  degrades gracefully if monai is ever decoupled.
- All three test files: skip on ``not torch.cuda.is_bf16_supported()``
  in addition to ``not torch.cuda.is_available()``. bf16 conv on
  pre-Ampere CUDA falls back to software emulation rather than failing,
  but the equivalence-vs-monai-fp32 tolerances were measured on Hopper
  — exclude older hardware where emulated bf16 could push drift past
  the configured rtol/atol.
- ``metrics.py`` docstring: "five Gaussian-mean convolutions" →
  "five uniform-window mean convolutions". Kernel is uniform
  (ones / prod(kernel_size)), not Gaussian.
- ``metrics.py`` helper: keep named ``y_pred_bf`` / ``y_bf`` views of
  the simple inputs going straight from the caller's dtype, instead of
  the fp32 round-trip ``y_pred_fp32.to(bf16)``. Saves a cast per simple
  input on the autocast path; under autograd the conv inputs are
  retained for backward either way, so this doesn't change peak
  memory.

Rejected:
- ``metrics.py`` capability gate / fp32 fallback. The plan deliberately
  chose unconditional bf16 convs (explicit casts, not autocast policy
  detection). bf16 conv works on every CUDA generation we ship to
  (sm_80+); on older CUDA it would emulate, not hard-fail. Falling back
  to fp32 for "any non-bf16 path" would reintroduce the Hopper
  bottleneck this PR exists to fix.

+# FCMAE VSCyto3D training on Hopper — ~10× slowdown vs pre-Hopper GPUs
+
+## Summary
+
+Pretrained FCMAE VSCyto3D finetunes for iPSC SEC61B (job 31297032) and TOMM20
+(job 31375338) train at roughly ~75 s/step on H200, vs ~5 s/step on L40S under
+the same config + pretrained checkpoint. The slowdown is consistent across
+Hopper GPUs (H100 and H200) and is **not** fixed by switching precision
+(fp16-mixed → bf16-mixed).
+
+## Verdict (2026-04-25) — MS-DSSIM is the dominant slow term
+
+Direct per-step measurements from a Lightning-config probe that drops
+the MS-DSSIM term from the loss (T2: `MixedLoss(l1_alpha=1.0,
+ms_dssim_alpha=0.0)`), 4 GPUs on H100 (gpu-f-6), `SEC61B_test48.zarr`,
+otherwise identical to the prod config:
+
+| Step | data_wait_ms | compute_ms |
+| ---: | ---:         | ---:       |
+| 0    | 8198         | 16397 *(init / cuDNN autotune)* |
+| 1    | 583.7        | 929.3      |
+| 2    | 594.7        | 903.7      |
+| 3    | 700.0        | 891.2      |
+| 4    | 609.2        | 2958.2     |
+| 5    | 583.3        | 1416.1     |
+| 6    | 560.0        | 935.7      |
+| 7    | 555.2        | 1257.7     |
+| 8    | 555.8        | 1241.8     |
+| 9    | 548.1        | 1870.6     |
+
+Steady-state floor on rank 0 is ~0.9 s/step compute. The same prod config
+**with** MS-DSSIM measured **45.5 s/step compute** on identical N=4 H100
+hardware (Probe C job 31451180 and T5 job 31451960, 8 and 4 consecutive
+steady-state STEP_TIMER lines respectively) — a **~50× delta** attributable
+to the MS-DSSIM term.
+
+A symmetric MS-DSSIM-only probe (T4) was queued but cancelled when its
+StartTime slipped 8 hours; the deduction is closed by subtraction:
+L1-only is fast, L1+MS-DSSIM is slow, therefore MS-DSSIM is the slow
+term.
+
+### Fix landed (2026-04-25) — bf16 SSIM helper, 11× speedup confirmed
+
+The fix replaces monai's `compute_ssim_and_cs` with a precision-aware
+helper `_compute_ssim_and_cs_bf16` (commit `e42c49a`) and drops the
+now-redundant `@torch.amp.custom_fwd(cast_inputs=fp32)` decorator from
+`MixedLoss` and `SpotlightLoss` (commit `3a7fa05`). The helper runs the
+5 Gaussian-mean convolutions in bf16 (with squared products computed in
+fp32 before casting, to preserve squaring precision) and promotes only
+the variance subtractions and C₁/C₂-guarded divisions to fp32.
+
+T6 sanity probe (job 31453564, gpu-f-2 H100, N=4, MS-DSSIM enabled,
+`SEC61B_test48.zarr`, otherwise identical to T5/Probe C):
+
+| Step | data_wait_ms | compute_ms |
+| ---: | ---:         | ---:       |
+| 0    | 11894.6      | 15674.9 *(init / cuDNN autotune)* |
+| 1    | 542.1        | 4139.3     |
+| 2    | 535.8        | 4140.2     |
+| 3    | 538.7        | 4143.2     |
+| 4    | 548.5        | 4155.6     |
+| 5    | 542.4        | 4164.7     |
+| 6    | 541.1        | 4166.4     |
+
+Steady-state mean compute_ms: **4151 ms** over 6 consecutive lines
+(std ~10 ms). Versus the **45.5 s/step** baseline on identical N=4 H100
+hardware with fp32 MS-DSSIM (Probe C `31451180`, T5 `31451960`):
+**~10.97× speedup**.
+
+The remaining ~4 s/step is the actual MS-DSSIM compute cost on Hopper
+in the bf16 regime — an order of magnitude faster than fp32, but still
+meaningfully more than the 0.9 s/step L1-only floor (T2). Further
+mitigation (reducing pyramid depth, MS-DSSIM frequency) would attack
+that residual; not pursued here since 4 s/step is workable for FCMAE
+finetune training.
+
+Validated by tests in `packages/viscy-utils/tests/test_metrics.py`,
+`test_mixed_loss.py`, and the extended `test_spotlight_loss.py`. The
+contract holds at: per-pixel rtol=5e-2/atol=1e-1 (random), aggregate
+rtol=1e-2/atol=1e-2 (random), aggregate rtol=2e-3/atol=5e-3
+(correlated-pair), gradient cosine similarity ≥0.99, sign-flip
+fraction <1% on `|grad_ref|>1e-3` voxels.
+
+The earlier "Hopper kernel / DDP bucket-view stride mismatch" hypothesis
+(see [Earlier diagnosis](#earlier-diagnosis-superseded) below) is wrong as
+a cause — the stride warnings are real but not load-bearing for the
+slowdown. A plain Lightning + synthetic-data + DDP probe on N=4 H100
+(no MS-DSSIM, no real data pipeline) ran at 185.6 ms/step steady-state,
+ruling out Lightning, DDP, cuDNN, and the data pipeline as the
+bottleneck.
+
+### Why MS-DSSIM is slow on Hopper
+
+The MS-DSSIM 5-level pyramid runs in fp32 — at every level,
+`compute_ssim_and_cs` (monai) executes 5 large-kernel convolutions
+(μₓ, μᵧ, μₓₓ, μᵧᵧ, μₓᵧ) with a `(D=15, 11, 11)` kernel; the multiscale
+wrapper then `avg_pool3d`-downsamples and repeats 5 times. The
+conv-heavy core therefore runs in fp32 regardless of any outer
+mixed-precision context.
+
+What the **measurement** establishes: with that path skipped (T2),
+compute drops from 45.5 s/step → ~0.9 s/step on identical N=4 H100
+hardware. So fp32 MS-DSSIM is dominating on Hopper.
+
+What is **inferred but not directly measured**: that the gap is
+specifically explained by Hopper's bf16/fp16-vs-fp32 tensor-core
+advantage being larger than Ampere's / Ada's. Plausible from
+published kernel ratios, but we have not benchmarked the same monai
+SSIM kernels across architectures. The cross-architecture explanation
+should be treated as the leading theory, not an established fact.
+
+### Where the fp32 cast comes from (two stacked sources)
+
+1. **monai's `compute_ssim_and_cs`** (`monai/metrics/regression.py:402-403`)
+   force-casts both inputs to fp32 unconditionally:
+
+   ```python
+   y_pred = convert_data_type(y_pred, output_type=torch.Tensor, dtype=torch.float)[0]
+   y     = convert_data_type(y,      output_type=torch.Tensor, dtype=torch.float)[0]
+   ```
+
+   This is what makes MS-DSSIM slow on Hopper. The 25 conv ops (5 stats ×
+   5 pyramid levels) all run with fp32 weights and fp32 inputs.
+
+2. **viscy's `MixedLoss.forward`** (`packages/viscy-utils/.../mixed_loss.py:43`)
+   adds an outer `@torch.amp.custom_fwd(cast_inputs=torch.float32)`.
+   Introduced in commit `b4ec13c` (PR
+   [#37](https://github.com/mehta-lab/VisCy/pull/37), 2023-08-30), which
+   focused on the pixelshuffle decoder — the cast came in alongside
+   without a justifying note in the PR review. The mechanic of
+   `custom_fwd(cast_inputs=...)` is "cast the inputs and run the
+   forward with autocast disabled," so the decorator really does
+   create an fp32 island when active. The pattern is the well-known
+   "force MS-SSIM to fp32 to avoid NaN under autocast" workaround
+   (cf. torchmetrics issue
+   [#2281](https://github.com/Lightning-AI/torchmetrics/issues/2281):
+   `σ² = E[X²] − μ²` subtraction produces tiny negative values from
+   float deviations, the C₁/C₂ stability constants don't cover them,
+   resulting in NaN; later fixed upstream). This is corroborated by
+   the `clamp=True` flag in our `ms_ssim_25d`, documented as "for
+   training stability when used in loss" — author was already fighting
+   numerical instability.
+
+   Today this outer cast is **largely redundant**: the conv-heavy core
+   inside monai is already pinned to fp32, so removing the `@custom_fwd`
+   decorator only affects `F.l1_loss`, `F.mse_loss`, and the outer
+   `F.avg_pool3d` downsamplings — none of which are the slow path.
+   Removing it alone does **not** unblock Hopper.
+
+### Mitigation options (revised)
+
+The bottleneck is monai's internal fp32 cast on the SSIM convs, not
+viscy's outer decorator. Practical fallback order:
+
+1. **Local-patch monai's `compute_ssim_and_cs` with a mixed-precision
+   variant** — keep variance-sensitive math in fp32, run convs/pooling
+   in bf16:
+   - convs (μₓ, μᵧ, μₓₓ, μᵧᵧ, μₓᵧ) and `avg_pool3d` between levels:
+     **bf16** (kernels and inputs both)
+   - `mu_xx − mu_x*mu_x`, `mu_yy − mu_y*mu_y`, `mu_xy − mu_x*mu_y`:
+     **fp32**
+   - C₁/C₂-guarded divisions for `contrast_sensitivity` and `ssim`:
+     **fp32**
+
+   bf16 keeps fp32's 8-bit exponent (vs fp16's 5-bit), so it is the
+   right candidate for SSIM's near-equal subtraction; fp16 should be
+   avoided. Validate numerical equivalence against the current fp32
+   path on a representative batch before training.
+
+2. **Reduce MS-DSSIM frequency** — e.g. apply the MS-DSSIM term every
+   N steps and L1-only on the others. No precision changes; degrades
+   loss signal but doesn't risk numerical regression.
+
+3. **Drop MS-DSSIM entirely** on Hopper finetune runs. Largest
+   behavior change; should be backed by parity training runs against
+   the L1+MS-DSSIM baseline.
+
+### Fastest confirmation experiment
+
+Patch `compute_ssim_and_cs` so that:
+
+- it does **not** immediately cast `y_pred` and `y` to fp32,
+- the convs run under autocast (bf16 on Hopper),
+- only the variance subtraction and C₁/C₂-guarded divisions are
+  explicitly promoted to fp32.
+
+Re-run the T2-style sanity probe with MS-DSSIM **enabled** and this
+patched path. If step time collapses from ~45 s toward the L1-only
+~0.9 s regime, that load-bearing identification is confirmed.
+
+> **Note:** dropping only the `@torch.amp.custom_fwd` decorator from
+> `MixedLoss.forward` (without touching monai's internal cast) will
+> **not** restore Hopper throughput — the 25 fp32 convs in the pyramid
+> remain. This was an earlier mitigation suggestion that I retracted
+> after reading monai's source.
+
+## Throughput measurements

+All rows below use the same `fcmae.ckpt`-warm-started FCMAE VSCyto3D model,
+`ddp_find_unused_parameters_true`, 4 GPUs, `z=15, yx=256`, `num_samples=4`,
+`mmap_preload=true`, `scratch_dir=/dev/shm`.
+
+### Pretrained finetune sanity probes across architectures
+
+All probes use `SEC61B_test48.zarr` (48 FOVs), pretrained FCMAE VSCyto3D
+warm-start, 4 GPUs, fp16-mixed unless noted, 3 epochs.

+
+**The architecture split is sharp:** every pre-Hopper GPU runs at 2.8–5.1
+s/step. Every Hopper run we have measured (H100 fp16, H200 fp16, H200 bf16,
+scratch H100 fp16, scratch H100 bf16) lands in 46–75 s/step — a **13–27×
+slowdown** across the Hopper boundary regardless of precision, warm-start,
+or which Hopper SKU.
+
+The two A100 attempts both NCCL-timed out during a 32 M-element BROADCAST
+in DDP setup before any training step. That number matches the FCMAE
+encoder param count (32.1 M), so the symptom is consistent with rank 0
+being slow to load `fcmae.ckpt` (or otherwise blocked on rank-0-only I/O)
+while ranks 1–3 sat at the collective and the 30-min watchdog fired. This
+is an I/O coordination problem on those A100 nodes' shared-storage path,
+not a hardware fault — and not informative for the Hopper-vs-Ampere
+question. (Separate follow-up: rerun A100 sanity with rank 0 staging
+`fcmae.ckpt` before the DDP barrier, or measure raw read bandwidth from
+gpu-a-3 / gpu-d-2 to `/hpc/projects/virtual_staining`.)
+
+### Scratch-vs-pretrained × fp16-vs-bf16 controlled matrix (H100)
+
+To rule out the warm-start `ckpt_path` + `encoder_only: true` path and
+precision as the cause, we ran the same sanity harness with random init
+(no `ckpt_path`, no `encoder_only`) across both precisions on identical
+H100 hardware.
+
+| Init       | Precision   | GPU  | s/step | Source |
+| ---        | ---         | ---  | ---:   | --- |
+| Scratch    | fp16-mixed  | H100 | 46.57  | sanity job 31402627 (step 9→19 / 466 s) |
+| Scratch    | bf16-mixed  | H100 | 46.33  | sanity job 31402692 (step 9→19 / 463 s) |
+| Pretrained | fp16-mixed  | H100 | 47.60  | sanity job 31400433 (step 9→29 / 951 s) |
+| Pretrained | bf16-mixed  | H200 | 65.80  | sanity job 31400431 (step 9→19 / 658 s) |
+
+All four Hopper runs cluster in 46–66 s/step vs L40S 5.1 s/step. The
+slowdown is invariant to:
+
+1. Precision (fp16 ↔ bf16: 46.57 vs 46.33 on scratch — no difference).
+2. Warm-start (scratch ↔ pretrained on fp16: 46.57 vs 47.60 — no
+   difference).
+3. Hopper generation (H100 vs H200: both in the same band).
+
+**No config knob fixes this.** The slowdown is intrinsic to the FCMAE
+ConvNeXt graph hitting a slow Hopper kernel path.
+
+### Scratch FCMAE (prod runs, same architecture)

+
+**No FCMAE run (scratch or pretrained) has successfully reached steady-state
+training throughput on Hopper.** The "scratch ran fine" runs were all on
+pre-Hopper hardware (A40, L40S, A100 attempts).
+
+<a id="earlier-diagnosis-superseded"></a>
+## Earlier diagnosis (superseded by 2026-04-25 verdict above)
+
+The notes below were the working hypothesis before the L1-only probe
+showed compute time collapses 50× when MS-DSSIM is removed. They are
+left for the record — the cuDNN/DDP-stride warnings are real, but they
+are not the cause of the slowdown.
+
+- `py-spy dump` on live H200 rank 0 (prod SEC61B, job 31297032) pinned the
+  MainThread inside `_engine_run_backward` (`torch/autograd/graph.py:865`)
+  across 3 consecutive snapshots. DataLoader workers (`pt_data_worker`),
+  pin-memory loop, and wandb threads were all idle. → **bottleneck is
+  GPU-side backward(), not data loading.** (Consistent with verdict —
+  MS-DSSIM has a heavy backward.)
+- Hopper stderr consistently emits DDP warnings that don't appear on L40S:
+  - `AccumulateGrad node's stream does not match the stream of the node that
+    produced the incoming gradient` (pointing at DDP + stream ordering).
+  - `Grad strides do not match bucket view strides ... grad.sizes() = [240, 960, 1, 1],
+    strides() = [960, 1, 960, 960] vs bucket_view ... [960, 1, 1, 1]`
+    (pointing at a specific layer whose weight grad memory format breaks DDP's
+    bucket view contract on Hopper).
+- Switching `precision: bf16-mixed` on H200 changed throughput from ~75 → 65.8
+  s/step — basically the same order of magnitude. **Precision is not the
+  cause.**
+
+Earlier working hypothesis (now wrong): a specific kernel/layer (likely a
+pointwise 1×1 conv in the FCMAE ConvNeXt encoder given the `[240, 960, 1, 1]`
+weight shape) hits a slow Hopper path, and DDP can't fuse its grads cleanly
+due to the stride mismatch. **The L1-only probe falsified this** — with
+MS-DSSIM removed, that same encoder graph runs at ~0.9 s/step on H100,
+so the encoder is not the slow path.
+
+## OOM after ~20 h (separate, unresolved issue)
+
+These same 4-GPU jobs have also hit host-RAM OOM after **~20 hours of
+successful training**, even on datasets with ample nominal headroom (ER
+SEC61B is 80 GB compressed / 199 GB uncompressed on a 512 GB allocation).
+Because the kill happens deep into training and not at peak, this is a **slow
+host-RAM leak**, not a peak-sizing problem. Bumping `--mem=640G` just buys
+runway — it does not address the leak.
+
+Likely suspects (not yet instrumented):
+- Persistent DataLoader workers drifting via torch multiprocessing ref-count
+  leaks on forked COW pages.
+- `mmap_preload` + `/dev/shm` state not reclaimed across epochs.
+- A zarr chunk / pin-memory cache growing unbounded.
+
+Open TODO: log per-rank RSS at each epoch boundary in a production run and
+correlate with memory pressure signals to pin the actual source.
+
+## Recommendation
+
+1. **Done (commits `e42c49a` + `3a7fa05`):** local bf16 SSIM helper +
+   redundant decorator removal landed. Hopper FCMAE compute is now
+   ~4.15 s/step (T6 measurement) vs ~45.5 s/step before — within an
+   order of magnitude of L40S throughput.
+2. Future training runs (fresh starts, intentional checkpoint
+   migrations) can now target Hopper directly. Active prod runs on
+   A40/L40S (jobs 31415937, 31446584) should not be precision-flipped
+   mid-resume.
+3. Separately, add RSS instrumentation and investigate the 20 h host-RAM
+   leak; do not treat the `--mem=640G` bump as a fix.

Subject: [PATCH 202/311] fix(viscy-data): drop use_thread_workers to fix DDP
 deadlock (#413)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(viscy-data): drop use_thread_workers to fix DDP deadlock

BatchedConcatDataModule used ThreadDataLoader(use_thread_workers=True),
which substitutes a thread-shim for multiprocessing.Process inside
PyTorch's worker iterator and silently forces persistent_workers=False.
That combination × real init_process_group hangs Lightning's
barrier("train_dataloader()") on a 4-GPU H200 node (SLURM 31453225).
Single-GPU and CPU+gloo DDP both worked, so the deadlock is
GPU/CUDA-specific (pin-memory thread × thread-shim worker context ×
per-rank CUDA context).

Drop use_thread_workers=True from train_dataloader and val_dataloader,
move the lambda collate to a module-level _identity_collate (spawn-safe),
and document why workers are now real subprocesses. The new
test_combined_ddp.py uses mp.start_processes(start_method="fork") to
spawn 2 real DDP ranks under pytest (mp.spawn requires start_method
"spawn", which can't re-resolve pytest's --import-mode=importlib path)
and parameterizes (num_workers, mmap_preload) ∈ {(0,F), (2,F), (2,T)}
— the last cell is the regression guard. Uses a deadline-loop join
because ctx.join returns False as soon as any rank exits, so a single
ctx.join(timeout=...) call is unsafe.

* refactor(viscy-data): /simplify cleanup of DDP fix + regression test

Simplify pass on combined.py + test_combined_ddp.py:

- Drop the homegrown ``_identity_collate`` helper; reuse
  ``monai.data.utils.no_collation``, which is character-identical and
  already available via the same ``monai.data`` namespace the file
  imports ``ThreadDataLoader`` from.
- Trim the change-narration tail on the ``BatchedConcatDataModule``
  docstring; the WHY belongs in the commit message, not the long-lived
  class doc.
- In the new test: drop the SLURM job number reference (transient task
  artifact), drop the hard-coded ``data_connector.py:93`` line number
  (rots across Lightning versions), drop the contributor-private
  ``/home/...`` path from the deadline-loop comment, and delete two
  WHAT-narration comments. Extract ``_kill_survivors`` so the
  terminate→join→kill sequence isn't duplicated between the deadline
  loop and the ``finally`` block. Replace the ``out_file.exists()``
  pre-check with a direct ``read_text()`` (per repo style: prefer
  raising errors over TOCTOU stat checks). Only ``mkdir`` the
  ``scratch_dir`` when ``mmap_preload=True`` actually needs it.

No behavior change. ``packages/viscy-data/tests/test_combined_ddp.py``
still passes all three parameter cells and ``test_combined.py`` is
unaffected.

* test(viscy-data): skip DDP test on platforms without fork

Copilot review on PR #413 flagged that the new
``test_combined_ddp.py`` hard-codes ``start_method="fork"`` and would
fail at runtime on the ``windows-latest`` matrix in
``.github/workflows/test.yml`` (Windows has no fork). Add a
``pytest.skip`` when ``"fork"`` is absent from
``mp.get_all_start_methods()``. Linux (CI default) keeps running all
three parameter cells; Windows now skips cleanly.

* docs(viscy-data): scope test docstring honestly to CPU+gloo coverage

Code-review feedback flagged that the test claims to "guard the
regression that broke production" but the deadlock is GPU/CUDA-specific
(pin-memory thread × thread-shim worker context under NCCL) per the
fix commit's own diagnosis — gloo/CPU passes even with the bug present.
The test still has value (locks down collate, sampler-attachment, rank-0
prepare_data ordering, mmap_preload) but the docstring oversold its
coverage. Reword to state the scope honestly and note that catching
a direct revert of ``use_thread_workers=True`` needs a GPU runner.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* test(viscy-data): guard against re-introducing use_thread_workers=True

CPU+gloo regression test in test_combined_ddp.py cannot reproduce the
GPU/NCCL-specific deadlock that PR #413 fixed (pin-memory thread ×
thread-shim worker context under CUDA), so a future revert of
``use_thread_workers=True`` would slip past CI.

This source-level check runs without DDP on every CI matrix cell.
It builds the joint loader with ``num_workers=2`` (the threshold MONAI
uses for the substitution) and asserts the resulting DataLoader's
``multiprocessing_context`` is not the
``monai.data.thread_buffer._ProcessThreadContext`` shim that
``use_thread_workers=True`` would install
(``monai/data/thread_buffer.py:189-191``).

Validated by temporarily re-adding ``use_thread_workers=True`` to
``BatchedConcatDataModule.train_dataloader`` and confirming the guard
fails on both zarr_v2 and zarr_v3 fixture parameterizations, then
removing the temp change before commit.

Subject: [PATCH 203/311] feat(dynacell): nucleus + membrane FCMAE_VSCyto3D
 scratch + pretrained leaves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the four FCMAE_VSCyto3D leaves needed to extend the existing
ER (sec61b) + Mito (tomm20) benchmark matrix to all four iPSC
organelles (ER / Mito / Nucleus / Membrane), each with a paired
{scratch, pretrained-encoder} pair so we have a paper-adjacent
init-ablation baseline per organelle.

Layout matches the existing ER/Mito leaves under
``benchmarks/virtual_staining/{er,mito}/fcmae_vscyto3d_{pretrained,scratch}/
ipsc_confocal/train.yml`` — same shared overlays
(``train_sets/ipsc_confocal``, ``data_overlays/fcmae_vscyto3d_fit``,
``model_overlays/fcmae_vscyto3d_fit``, ``hardware_4gpu``) and the same
``benchmark.dataset_ref`` pattern. Pretrained leaves load encoder-only
weights from ``/hpc/projects/virtual_staining/models/mehta-lab/VSCyto3D/
fcmae.ckpt`` (the canonical 400 ep VSCyto3D ckpt); scratch leaves are
random-init.

Both nucleus and membrane targets resolve to the multi-marker
``cell.zarr`` (Nuclei / Membrane channels respectively) per the
aics-hipsc manifest at ``configs/datasets/aics-hipsc/manifest.yaml``,
so no new zarrs needed.

Resolved configs validated end-to-end via
``submit_benchmark_job.py --print-resolved-config``; all four compose
cleanly with the bf16-SSIM-helper-equipped ``viscy_utils`` at HEAD.

Subject: [PATCH 204/311] fix(dynacell): override Structure aug-keys for
 nucleus + membrane FCMAE leaves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Job 31474018 (FCMAE_VSCyto3D_Pretrained_Nucleus) crashed with
``KeyError: 'Structure'`` from ``RandWeightedCropd`` 47 minutes in.
Root cause: ``_internal/shared/model/data_overlays/fcmae_vscyto3d_fit.yml``
hardcodes ``keys: [Phase3D, Structure]`` and ``w_key: Structure`` — that
overlay was authored for ER (sec61b) and Mito (tomm20), which both
have ``target_channel == "Structure"``. Compose's list-replace semantics
mean the data overlay's augmentations list completely overrides the
target overlay's augmentations, so the per-organelle channel name from
``targets/{nucleus,membrane}.yml`` (Nuclei / Membrane) never reaches
``RandWeightedCropd``.

Fix at the leaf level: each of the 4 nucleus + membrane FCMAE leaves
now declares its own ``data.init_args.augmentations`` with the right
channel name. The leaf is composed last, so its augmentations list wins
over the data overlay. The augmentation policy (spatial_size [20, 600,
600], num_samples 4, RandWeightedCropd as the only CPU aug) is kept
identical to the FCMAE overlay so behaviour matches ER/Mito.

A more robust fix would be to make the FCMAE data overlay's CPU
augmentation block parameterized by ``target_channel`` (or to drop it
from the overlay entirely and rely on the per-target overlay), but
that's broader infra surgery — leaving for a separate refactor.

ER (sec61b) and Mito (tomm20) FCMAE leaves are unchanged because they
already work — their target_channel is "Structure".

Subject: [PATCH 206/311] feat(dynacell): unblock joint training + add A549
 cross-eval (#415)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* chore(deps): pin iohub to PR #408 (RFC-9 zipped OME-Zarr); bump Python to >=3.12

Pin iohub to czbiohub-sf/iohub PR #408 head SHA
(53b10acb7a30a2c7e8dfd9b04258dea073e14088 — "feat: Added RFC-9 Zipped
OME-Zarr"). The PR adds zipped OME-Zarr store support; this pin
unblocks downstream consumers before the PR merges upstream.

The PR's iohub head requires Python >=3.12, so bump every workspace
pyproject.toml's `requires-python` from >=3.11 to >=3.12, drop the
3.11 classifier, and update ruff `target-version` to py312. Also
folds in the previously-pending dynacell[wandb] optional-extra
registration that the lockfile was already lagging on.

SHA pin (not branch) survives force-pushes; bump deliberately when
the PR moves.

* feat(dynacell): bake A100 exclusion into hardware_4gpu launcher profile

After repeat NCCL BROADCAST/ALLREDUCE coordination hangs at first-batch
on this cluster's A100 partition (FCMAE jobs 31474030 + 31474038 timed
out at 1h13m / 1h21m on watchdog; joint smoke 31480607 hung
indefinitely at `Loading 'train_dataloader'` on gpu-a-3), every 4-GPU
train leaf needed the same `--override
launcher.sbatch.constraint='h100|h200|a40|a6000|l40s'` workaround.
Job 31481032 with that override scheduled to gpu-h-3 (H100) and pushed
past the same hang point, confirming the workaround.

Bake the exclusion into the shared profile so it applies by default to
all 11 4-GPU consumers (FCMAE pretrained × 4 + scratch × 4 + er/unext2
+ joint celldiff train.yml + train_smoke_4gpu.yml). Leaves that
genuinely need A100 must opt out via
`--override launcher.sbatch.constraint=null`.

Lock-in test: `test_4gpu_train_leaves_inherit_a100_exclude` walks
every train leaf under benchmarks/virtual_staining/ and asserts the
constraint on 4-GPU leaves; new leaves picking up the profile are
covered automatically.

* fix(viscy-data): port to iohub 0.3.2 ImageArray API (#407)

The iohub PR #408 pin (Commit 1) ships a refactored ``ImageArray`` API
that removed ``ImageArray.name`` and other legacy attributes used
across viscy-data, viscy-utils, dynaclr, and qc. Without this port,
the existing test suite fails immediately on dataset iteration
(``AttributeError: 'ImageArray' object has no attribute 'name'`` at
``sliding_window.py``).

Cherry-picks the migration shipped in PR #407 (squash 737cedf on
``modular-viscy-staging``), preserving local extensions:

- ``sliding_window.py``: take ``f"/{img.path}"`` from #407 (replaces
  ``img.name``) but keep dynacell-models's ``to(torch.float32, copy=True)``
  cast on the mmap_preload path (post-dates #407).
- ``viscy-data/pyproject.toml``: keep ``iohub>=0.3.2`` lower bound from
  #407; the ``[tool.uv.sources]`` SHA pin in the workspace root
  pyproject.toml (Commit 1) is what actually controls resolution.
- ``uv.lock``: regenerate.

All 25 ``packages/viscy-data/tests/test_combined.py`` tests pass post-
migration, including the previously-failing
``test_combined_datamodule_fit``.

* fix(viscy-data): propagate trainer to children in ConcatDataModule.setup

Under DDP, ``Trainer.fit`` calls ``prepare_data`` only on rank 0 of each
node when ``prepare_data_per_node=True``, but ``setup`` runs on every
rank. ``ConcatDataModule.prepare_data`` forwarded ``self.trainer`` to
each child datamodule; ``setup`` did not. As a result, non-rank-0
children kept ``self.trainer = None``, and trainer-gated paths in the
children's ``on_after_batch_transfer`` silently skipped — most visibly
``HCSDataModule``'s
``if self.trainer and self.trainer.training`` guard at ``hcs.py:628``,
which gates ``gpu_augmentations``.

Production failure: SLURM 31481032 (joint celldiff smoke on 4× H100,
post-PR #413 + post-A100-exclude). Ranks 1, 2, 3 raised
``ValueError: x spatial size [13, 624, 624] does not match expected
[8, 512, 512]`` at the first training step — rank 0 ran fine because
its child had received the trainer via ``prepare_data``. Rank
asymmetry was the smoking gun.

Fix: propagate ``dm.trainer = self.trainer`` at the top of each loop
iteration in ``setup``, mirroring ``CombinedDataModule.setup`` (which
was already correct). Same fix applied to ``CachedConcatDataModule``,
which has the identical latent bug. ``BatchedConcatDataModule``
inherits from ``ConcatDataModule`` so the fix flows through.

Single-process regression test exercises the bug by skipping
``prepare_data`` entirely (mimicking the non-rank-0 lifecycle) and
asserting that ``setup`` alone propagates the trainer and that
``gpu_augmentations`` actually run through ``on_after_batch_transfer``.
The existing ``test_combined_ddp.py`` (gloo, ``pin_memory=False``, no
``gpu_augmentations``) cannot catch this — it doesn't exercise the
gpu-aug branch.

* test(dynacell): mirror a549-mantis manifest fixtures (3 plates)

Add three local fixture manifests so VisCy's dataset_ref resolver
tests can resolve a549-mantis datasets without requiring a
``dynacell-paper`` install. Mirrors the canonical manifests at
``dynacell-paper/_configs/datasets/a549-mantis/<date>/manifest.yaml``
landed via dynacell-paper PRs A1.1 (#14) and A2.1 (#15) plus the
prior aeef64c registration.

- ``a549-mantis-2024_10_29`` — TOMM20 plate (mito cross-eval).
- ``a549-mantis-2024_11_07`` — SEC61B plate (er cross-eval; also
  feeds the joint celldiff train leaf).
- ``a549-mantis-2026_03_26`` — h2b/caax mantis_v2 plate
  (nucleus + membrane cross-eval).

Resolver discovery: ``DYNACELL_MANIFEST_ROOTS`` is set to
``tests/fixtures/manifests/`` by the autouse
``_dynacell_manifest_root_env`` fixture in ``tests/conftest.py``.
Layout matches existing aics-hipsc fixture
(``<root>/<dataset_name>/manifest.yaml`` per
``resolver.py:131-140``); ``splits/`` subdirs are not mirrored
because the resolver doesn't read them.

Closes Stage 5 of A549_EXPANSION_ROADMAP.md on the VisCy side and is
the prerequisite for Stage 6 cross-eval leaves.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(dynacell): add a549_mantis predict_set fragments + Stage 6 cross-eval leaves

Closes Stage 6 of A549_EXPANSION_ROADMAP.md: every existing iPSC-trained
``<organelle>/<model>/ipsc_confocal/`` cell now has a sibling
``predict__a549_mantis.yml`` + ``eval__a549_mantis.yaml`` so iPSC-trained
models can be evaluated on the a549 test split.

8 cells × 2 leaves + 8 eval symlinks + 6 predict_set fragments
= 30 file additions.

Predict_set fragments are per-plate because the a549-mantis registry is
split by acquisition date:

- ``2024_11_07`` — SEC61B (er cross-eval)
- ``2024_10_29`` — TOMM20 (mito cross-eval)
- ``2026_03_26`` — H2B + CAAX (nucleus + membrane cross-eval)

Each fragment exists on both the model side
(``_internal/shared/model/predict_sets/``) and the Hydra side
(``dynacell/evaluation/_configs/predict_set/``), matching the existing
ipsc_confocal pattern.

Stage 6 leaves keep the iPSC-trained checkpoint and inherit the cell's
per-model predict configuration; only the predict_set base, output
store, and ``benchmark.experiment_id`` differ. CellDiff outputs use
``_iterative`` suffix; UNetViT3D outputs do not.

Nucleus + membrane leaves additionally set
``benchmark.dataset_ref.target: h2b`` (or ``caax``) at the leaf level —
the iPSC manifest keys those targets by `nucleus`/`membrane` while a549
keys them by gene. Eval leaves also override
``target_name: h2b`` (or ``caax``) so the segmentation / cache layers
(``mask_plate(target_name)`` → ``{target_name}.zarr``) remain consistent
if ``compute_feature_metrics`` is enabled later.

A549 manifests don't currently carry ``cell_segmentation`` or
``gt_cache_dir`` paths (no segmentation pipeline yet), so eval leaves
set ``compute_feature_metrics: false``. Pixel metrics (PCC, SSIM, NRMSE,
PSNR, FSC, spectral PCC) work without segmentation. Flip the flag in a
follow-up once segmentation lands in dynacell-paper.

Composition tests:

- ``test_a549_predict_leaf_composes`` parametrizes over the 8-cell
  matrix and asserts ``data.init_args.{data_path, source_channel,
  target_channel}``, ``benchmark.dataset_ref.{dataset, target}``,
  ``experiment_id``, and ``launcher.sbatch.constraint == 'h200'``
  (single-GPU predict topology).
- ``test_a549_eval_leaf_composes_and_splices`` composes each Hydra eval
  leaf, calls ``apply_dataset_ref(cfg)``, and asserts ``io.{gt_path,
  gt_channel_name, pred_channel_name}``, ``cell_segmentation_path is
  None``, ``gt_cache_dir is None``, manifest spacing (mantis_v1 0.1494
  µm vs mantis_v2 0.116 µm), and ``compute_feature_metrics is False``.

16 new tests, all green.

* refactor: /simplify cleanup of joint-training + a549 cross-eval branch

Apply post-implementation simplification per /simplify review:

- ``combined.py``: drop SLURM job ID from ``ConcatDataModule`` Notes block.
  Symptom (rank-asymmetric un-cropped batches) is non-obvious and stays;
  the specific failing job belongs in PR description, not a docstring
  that ages out.
- ``test_combined.py``: switch ``SimpleNamespace`` fake trainer to
  ``MagicMock`` to match the existing pattern in ``test_hcs.py``. Move
  imports to module level (per CLAUDE.md "Import at the top of the
  file"). Drop redundant inline narration comments.
- ``hardware_4gpu.yml``: trim 4 SLURM job IDs from the rationale block
  (task narration; belongs in PR/commit messages) and drop the rotting
  "11 4-GPU consumers (FCMAE × 8 + ...)" count — the data-driven
  ``test_4gpu_train_leaves_inherit_a100_exclude`` enforces the invariant
  without needing a maintenance-prone count in a YAML comment.

No behavior change. All previously-green tests remain green.

* docs(dynacell): clarify _A549_EVAL_EXPECTATIONS shape comment

The comment listed four fields, but the dict values are 3-tuples (the
organelle is the dict key, not part of the value). Rewrite as
``{organelle: (target_group, gt_channel, gt_suffix)}`` so the shape is
unambiguous when the matrix is extended.

From 6c75284df87be52463b53391762fdba7beb292f0 Mon Sep 17 00:00:00 2001

Subject: [PATCH 207/311] docs(dynacell): final findings + 8-job FCMAE
 benchmark, open items
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a "Final findings (2026-04-26) — bf16 fix shipped, 4-organelle
benchmark in flight" section that:

- States the solution in one paragraph (bf16 SSIM helper +
  redundant-decorator removal, with reference to the merged PR #412
  squash commit 48f4878).
- Records the live 4-organelle x {scratch, pretrained} = 8-job FCMAE
  matrix with median + p10 s/step, sourced directly from wandb
  loss/train_step step x timestamp deltas (dt < 60s filter excludes
  ckpt/val/epoch boundaries — directly measured per the
  no-walltime-estimates rule).
- Calls out three claims we can support today:
    * pre-fix Hopper at 45-75 s/step -> post-fix at 4.77-5.76 s/step,
      9-14x recovery
    * Hopper now competitive with L40S but not visibly faster
    * A40 (gpu-c-1) still wins at 2.40 s/step steady-state for
      reasons not yet measured (node-local I/O, /dev/shm topology,
      etc.); same shared-FS data path as Hopper, so the difference is
      on the compute-node side.
- Lists what's still open: warmup-vs-steady-state on Hopper (current
  numbers are gstep < 1.7k vs A40 baseline at gstep 35k), an unprofiled
  A40-vs-Hopper compute-path gap, the 20h host-RAM leak (separate
  thread), and the A100 NCCL BROADCAST hang (mitigation in place via
  --constraint='h100|h200|a40|a6000|l40s' but root cause not
  investigated).

Adds Recommendation #4 (the A100 exclude). Numbers explicitly noted as
"will be re-pulled once new Hopper jobs reach gstep >=10k" so the
follow-up is on the page, not a chat-only TODO.

+   `--constraint='h100|h200|a40|a6000|l40s'`. Two FCMAE scratch jobs
+   on A100 nodes (gpu-a-1, gpu-a-2) hit a ~30-min NCCL watchdog
+   timeout on the SeqNum-13 BROADCAST of the 32,148,528-element
+   encoder weights during DDP setup — same I/O coordination problem
+   that killed the earlier A100 sanity attempts. The bf16 fix doesn't
+   address this; it's an A100-shared-storage issue.
+
+## Final findings (2026-04-26) — bf16 fix shipped, 4-organelle benchmark in flight
+
+### Solution (one paragraph)
+
+The viscy-utils SSIM helper (`packages/viscy-utils/src/viscy_utils/
+evaluation/metrics.py`) replaces monai's fp32-pinned
+`compute_ssim_and_cs` with a precision-aware variant that runs the 5
+uniform-window mean convolutions in bf16 with squared products
+computed in fp32 *before* casting to bf16, and promotes only the
+variance subtractions and C₁/C₂-guarded divisions back to fp32.
+Redundant `@torch.amp.custom_fwd(cast_inputs=fp32)` decorators on
+`MixedLoss.forward` and `SpotlightLoss.forward` were removed in the
+same PR. Numerical contract is documented and tested with a 4-tier
+tolerance (per-pixel random, aggregate random, correlated-pair,
+gradient cosine + sign-flip) at ≥2× margin over measured drift. PR
+[#412](https://github.com/mehta-lab/VisCy/pull/412) merged as squash
+commit `48f4878`.

+Numbers come from wandb `loss/train_step` step×timestamp deltas with
+a `dt < 60s` filter (excludes ckpt-save / val / epoch-boundary
+insertions). All 8 jobs request `--mem=1024G` except the L40S baseline
+at 768G (CPU/RAM is not the driver). **All numbers will be re-pulled
+once the new Hopper jobs reach gstep ≥10k** — they are still in epoch
+0 (gstep < 1.7k) and warmup effects (DataLoader cache, mmap_preload,
+prefetch) likely inflate the per-step time. Steady-state from
+gstep ≥30k on A40/L40S is reliable.
+
+### What we can claim now
+
+- **Catastrophic Hopper slowdown is fixed.** Pre-fix Hopper measured
+  45–75 s/step; post-fix Hopper sits in 4.77–5.76 s/step — a 9–14×
+  recovery, within the same order of magnitude as L40S/A40.
+- **Hopper is now competitive but not visibly faster than L40S.** The
+  bf16 fix unblocks the catastrophic kernel cost but doesn't expose
+  a Hopper-specific tensor-core advantage in the end-to-end loop.
+- **A40 (gpu-c-1) is still the fastest measured path** at 2.40 s/step
+  steady-state. Likely drivers (not yet measured): node-local I/O for
+  zarr reads, /dev/shm topology, PCIe + CPU-worker layout. Same
+  shared-FS data path as Hopper, so the differentiator is on the
+  compute-node side.
+
+### What remains open
+
+- **Hopper steady-state vs warmup.** Will re-measure once new jobs
+  reach gstep ≥10k. Hopper might converge to ~A40 throughput once
+  caches warm, or may stay ~5 s/step (would suggest a stable
+  data-pipeline ceiling).
+- **A40 vs Hopper compute path.** No profiler / `iostat` /
+  `nvidia-smi dmon` data on either side. If Hopper steady-state stays
+  above ~3 s/step, a 5-min profiling probe on both nodes during
+  steady-state would isolate the bottleneck (data I/O vs GPU compute
+  vs DDP collective).
+- **20-hour host-RAM leak** still unresolved (separate thread, see
+  above). Independent of the bf16 fix.
+- **NCCL BROADCAST hang on A100** is a known I/O coordination issue
+  on those specific nodes' shared-storage path. Mitigation in place
+  (constraint OR-list); root cause not investigated.

Subject: [PATCH 208/311] docs(dynacell): clean up resolved planning docs;
 refresh A549 roadmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove three temporary planning docs whose work has shipped, and
refresh the overall A549 expansion roadmap to reflect current
progress, gaps, and next steps.

Removed:
- DATASET_REF_RESOLVER_SPEC.md — Stages 1-3 spec; all merged
  (38d47b3, 4bb9f09, 11836c8, 326b2d0, 6273439, 8924ab2, f5a6e56,
  a984384).
- fcmae_hopper_slowdown.md — bf16 SSIM kernel fix shipped via PR #412
  (squash 48f4878); 4-organelle FCMAE benchmark complete.
- submit-reliability-plan.md — Gap 1 (--exclude SBATCH directive)
  and Gap 3 (NCCL preflight smoke test) merged into
  submit_benchmark_job.py + sbatch_template.sbatch +
  tools/nccl_smoke_test.py; Gap 2 (auto-requeue) explicitly deferred
  upstream of the doc.

A549_EXPANSION_ROADMAP.md refresh:
- Status snapshot table: Stages 1-3 done with commit refs; Stage 5
  partial (canonical manifests in dynacell-paper @ aeef64c, VisCy
  fixture mirror still missing); Stage 6 not started; Stage 7 (joint
  training) in flight with first leaf shipped.
- Reconcile commit-message "Stage 7" with the roadmap by promoting
  joint-training leaves to a first-class stage (was implicit under
  the old Stage 6 description).
- Drop the now-stale DATASET_REF_RESOLVER_SPEC.md cross-reference.
- Trim ~234 → ~130 lines: collapse done stages, keep open work.

 # A549 Expansion Roadmap
 
-## Context
-
-The current `virtual_staining/` tree is populated only for `ipsc_confocal`
-training and evaluation. Research requirements expand this to:
-
-- **Two training sets per (organelle, model) cell**: `ipsc_confocal` and
-  `joint_ipsc_confocal_a549_mantis`.
-- **Two held-out evaluation splits per trained model**: `ipsc_confocal`
-  and `a549_mantis`. Every trained model evaluates on both, regardless of
-  training source, so cross-dataset transfer is measurable.
-
-The post-reorg layout (`14f59f1`) already supports this — each
-`<org>/<model>/<train_set>/` dir is a training experiment with room for
-multiple `predict__<predict_set>.yml` and `eval__<predict_set>.yaml`
-leaves. The gap is the underlying **data-path plumbing**: every leaf
-today hardcodes `data_path`, `source_channel`, `target_channel` (for
-train/predict) or `gt_path`, `cell_segmentation_path`, `gt_cache_dir`
-(for eval). Naively expanding to a549 duplicates all of this across
-roughly 60 new leaves, which becomes technical debt the moment any path
-moves.
-
-`DATASET_REF_RESOLVER_SPEC.md` proposes exactly the right fix for the
-train/predict side: a manifest-driven resolver so leaves reference a
-dataset by name (`benchmark.dataset_ref: {dataset, target}`) and the
-composition layer splices in paths and channels from a Pydantic
-manifest. This roadmap sequences the resolver PR, its follow-ups, and
-the a549 expansion so each stage lands on top of a solid foundation.
-
-## How the two workstreams relate
-
-- **Question B from the a549 scoping discussion** (how to disentangle
-  organelle identity from dataset-specific paths in `target/` YAMLs) is
-  precisely what the resolver solves. The manifest owns the paths; the
-  Hydra `target/` group owns only channel names and organelle identity.
-- Duplicating a549-variant target YAMLs today (`er_sec61b_a549.yaml` and
-  friends) would write exactly the path duplication the resolver is
-  designed to eliminate. Don't do it.
-- The spec's non-goal #1 is eval-side resolution; the a549 eval
-  expansion needs that, so we either wait for the eval-side follow-up
-  or write eval leaves with hardcoded paths (debt). This roadmap waits.
-
-## Staged plan
-
-### Stage 1 — Resolver PR (per `DATASET_REF_RESOLVER_SPEC.md`)
-
-Scope exactly as the spec describes:
-
-- `packages/viscy-utils/src/viscy_utils/compose.py`: add optional
-  keyword-only `resolver: Callable[[dict], dict] | None` to
-  `load_composed_config`.
-- `applications/dynacell/src/dynacell/data/manifests.py`: add
-  `DatasetRef` Pydantic model.
-- `applications/dynacell/src/dynacell/data/resolver.py`: new module with
-  `ResolvedDataset`, `discover_manifest_roots`, `resolve_dataset_ref`,
-  three error classes.
-- `applications/dynacell/src/dynacell/_compose_hook.py`:
-  `_dynacell_ref_resolver` that reads `composed["benchmark"]["dataset_ref"]`,
-  infers mode, splices `data_path` / `source_channel` / `target_channel`.
-- Wire the hook in `dynacell/__main__.py` and `tools/submit_benchmark_job.py`.
-- Manifest-root precedence: CLI roots → `DYNACELL_MANIFEST_ROOTS` env
-  var → `dynacell.manifest_roots` entry points.
-- Collision policy: leaves with both `dataset_ref` and explicit
-  `data_path` raise `ValueError`.
-- Migrate exactly one target (`er_sec61b` + `ipsc_confocal` train_set)
-  to prove end-to-end composition is byte-identical to pre-PR output.
-
-Tests: `test_dataset_ref.py` (unit — resolver + error messaging),
-`test_compose.py` (viscy-utils resolver kwarg contract), expansion to
-`test_benchmark_config_composition.py` (integration, one migrated
-target). Full dynacell suite green.
-
-Exit criteria: one migrated leaf composes identically to today;
-remaining 16 train leaves + 8 predict leaves + 8 eval leaves untouched.
-
-### Stage 2 — Migrate remaining train/predict targets
-
-`mito_tomm20`, `membrane`, `nucleus` move onto `dataset_ref` in the
-train/predict overlays — bundled in **one VisCy PR** (each target is
-a two-line fragment change; splitting fragments the test delta and
-buys nothing). Scope: three target fragments, six predict leaves
-that drop their explicit `data_path`, a fixture manifest update
-adding `nucleus` + `membrane` entries, and a companion
-`dynacell-paper` manifest PR that adds the same two entries to the
-canonical manifest (required for production runs; VisCy tests pass
-against the repo-local fixture). Behavior stays identical; integration
-tests parametrize across every model in `TRAIN_LEAVES` /
-`PREDICT_LEAVES` that composes a migrated fragment to guard against
-drift.
-
-### Stage 3 — Hydra-side hook + migrate all four eval target YAMLs
-
-Extend `dataset_ref` resolver to the Hydra/eval side. Add post-compose
-hook (`_ref_hook.py`) at `evaluate_model` / `precompute_gt` entry
-points. Migrate all four eval target YAMLs (`er_sec61b`, `mito_tomm20`,
-`nucleus`, `membrane`) + `predict_set/ipsc_confocal.yaml` together so
-`io.*` and `pixel_metrics.spacing` come from the manifest. Add
-`gt_cache_dir` to `StoreLocations`.
-
-Deliverables:
-
-- New `applications/dynacell/src/dynacell/evaluation/_ref_hook.py`.
-  The hook fires inside the `evaluate_model()` and `precompute_gt()`
-  entry-point function bodies (not during Hydra compose), reads
-  `composed["benchmark"]["dataset_ref"]`, and splices the manifest
-  fields into the composed config before `pipeline.py` consumes it.
-- `ResolvedDataset` extended with `cell_segmentation_path` and
-  `gt_cache_dir` fields.
-- Four migrated eval target YAMLs (`_internal/shared/eval/target/*.yaml`):
-  each keeps only `target_name` and `benchmark.dataset_ref.target`;
-  `io.gt_path`, `io.cell_segmentation_path`, `io.gt_channel_name`,
-  `io.pred_channel_name`, `io.gt_cache_dir` all come from the manifest.
-  `pred_channel_name` is derived in the hook as
-  `f"{target_channel}_prediction"` and is not stored in the manifest.
-- Migrated `_configs/predict_set/ipsc_confocal.yaml`: contributes only
-  `benchmark.dataset_ref.dataset`; `pixel_metrics.spacing` comes from
-  the manifest.
-- `benchmark: null` placeholder added to `_configs/eval.yaml` so the
-  node exists for the hook to populate.
-- Hydra-branch error catch wired into `dynacell/__main__.py` so hook
-  errors surface as user-facing messages.
-- Integration tests extended with Layer 2 entry-point wiring coverage
-  (the hook actually runs through `evaluate_model` / `precompute_gt`,
-  not just called directly).
-
-The `gt_cache_dir` addition to `StoreLocations` requires a companion
-bump to the canonical `dynacell-paper` manifest — see the planned
-spec at `~/.claude/plans/dynacell-paper-stage3-gt-cache-dir.md` (or a
-companion spec if the path hasn't been published yet). Pydantic's
-default `extra="ignore"` on `StoreLocations` makes the ordering
-constraint an auditing preference, not a schema-parsing requirement —
-older manifests without `gt_cache_dir` still parse.
-
-### Stage 4 — Merged into Stage 3
-
-Stage 4 (migrate eval target YAMLs) has been folded into Stage 3 and
-lands in the same PR. See Stage 3 above. Any downstream references to
-"after Stage 4" now mean "after the combined Stage 3".
-
-### Stage 5 — Add a549 manifest
-
-Register `aics-a549-mantis` (slug TBD) in the manifest registry:
-
-- `data_path_train`, `data_path_test` per organelle target
-- `source_channel`, `target_channel`
-- `spacing` (voxel dimensions)
-- Eval-side fields: `gt_path`, `cell_segmentation_path`,
-  `gt_cache_dir`, `gt_channel_name`
-
-Lives in `dynacell-paper` (or wherever the canonical manifest source
-is). Independent of VisCy changes — can proceed in parallel with
-Stage 3.
-
-### Stage 6 — A549 leaf expansion
-
-With the resolver in place on both sides, each new leaf is 5-10 lines:
+Multi-stage rollout adding A549/mantis-lightsheet alongside the
+existing iPSC/confocal benchmark cells, with a manifest-driven
+dataset resolver as the foundation.
+
+## Goal
+
+- **Two training sets per (organelle, model) cell**: `ipsc_confocal`
+  and `joint_ipsc_confocal_a549_mantis`.
+- **Two held-out evaluation splits per trained model**:
+  `ipsc_confocal` and `a549_mantis`. Every trained model evaluates on
+  both, regardless of training source, so cross-dataset transfer is
+  measurable.
+
+The post-reorg layout (`14f59f1`) supports this — each
+`<org>/<model>/<train_set>/` dir is a training experiment with room
+for multiple `predict__<predict_set>.yml` and
+`eval__<predict_set>.yaml` leaves. The resolver removed the data-path
+duplication that would otherwise blow up across ~60 new leaves.
+
+## Status snapshot (2026-04-26)
+
+| Stage | Description | Status |
+|---|---|---|
+| 1 | Resolver core + 1 migration (`er_sec61b`, `ipsc_confocal`) | **Done** — `38d47b3`, `4bb9f09` |
+| 2 | Migrate `mito_tomm20`, `nucleus`, `membrane` to `dataset_ref` | **Done** — `11836c8`, `326b2d0`, `6273439` |
+| 3 | Hydra-side hook + 4 eval target YAMLs migrated | **Done** — `8924ab2`, `f5a6e56`, `a984384` |
+| 4 | (folded into Stage 3) | n/a |
+| 5 | Register a549-mantis manifests | **Partial** — done in dynacell-paper (`aeef64c`, 7 per-plate manifests 2024_10_29 → 2025_08_26); VisCy fixture mirror missing |
+| 6 | Single-dataset a549 predict + eval leaves | **Not started** |
+| 7 | Joint training leaves (ipsc + a549) | **In flight** — first leaf only (`er/celldiff`); the 4-GPU DDP deadlock that blocked the full path is fixed (PR #413, `0b04b24`) |
+
+## Remaining work
+
+### Stage 5 — finish the VisCy fixture mirror
+
+The canonical a549-mantis manifests live in `dynacell-paper`. VisCy
+integration tests still resolve only `aics-hipsc` (single fixture
+under `applications/dynacell/tests/fixtures/manifests/`). Before
+Stage 6 can be tested without a `dynacell-paper` install, add an
+`a549-mantis/manifest.yaml` fixture mirror (one date is enough — pick
+the one currently consumed by Stage 7's joint leaf,
+`2024_11_07/manifest.yaml`).
+
+### Stage 6 — single-dataset a549 predict + eval leaves
+
+Add `predict__a549_mantis.yml` + `eval__a549_mantis.yaml` to existing
+`<organelle>/<model>/ipsc_confocal/` cells so iPSC-trained models can
+be evaluated on the a549 test split.
+
+Sub-scope (from the original roadmap, still unresolved):
+
+- **(iv) full-but-predictable-only** — the 8 cells that already have
+  `<model>_predict.yml` overlays (celldiff + unetvit3d × 4 organelles).
+  Recommended starting point.
+- **(iii) full-all-models** — additionally create skeleton
+  `fcmae_vscyto3d_predict.yml`, `fnet3d_paper_predict.yml`,
+  `unext2_predict.yml` overlays. Defer unless needed.
+
+Each leaf is 5–10 lines:
 
 ```yaml
 # eval__a549_mantis.yaml
-# @package _global_
 defaults:
   - override /target: er_sec61b
 benchmark:
-  dataset_ref: {dataset: aics-a549-mantis, target: sec61b}
+  dataset_ref: {dataset: a549-mantis-2024_11_07, target: sec61b}
 io:
   pred_path: /hpc/.../sec61b_celldiff_on_a549.zarr
 save:
   save_dir: /hpc/.../eval_sec61b_celldiff_on_a549
 ```
 
-The expansion matrix:
+### Stage 7 — joint training leaf expansion
 
-- Fill in every `<org>/<model>/ipsc_confocal/` with
-  `predict__a549_mantis.yml` + `eval__a549_mantis.yaml`.
-- Create `<org>/<model>/joint_ipsc_confocal_a549_mantis/` with
-  `train.yml` + `predict__ipsc_confocal.yml` +
-  `predict__a549_mantis.yml` + `eval__ipsc_confocal.yaml` +
-  `eval__a549_mantis.yaml`.
-- Corresponding `_internal/leaf/` symlinks for every new eval leaf.
+The joint-loader infrastructure landed in `4bc2e53` (sharded sampler
+in `BatchedConcatDataModule`) and `5950576` (split fit overlays). PR
+#413 fixed the production 4-GPU DDP deadlock. The first joint leaf
+shipped at `er/celldiff/joint_ipsc_confocal_a549_mantis/train.yml`
+(`9654e2b`); smoke variants followed (`4d399d5`, `234819a`).
 
-Sub-scope to decide when we get here (question A from earlier):
+Joint leaves bypass the single-dataset `dataset_ref` resolver and
+author the data block inline because hparams live on each child.
+Shared HCS init_args factor via a YAML merge anchor.
 
-- **(iv) full-but-predictable-only** — add predict/eval leaves only for
-  the 8 cells that have `<model>_predict.yml` overlays (celldiff,
-  unetvit3d × 4 organelles). Start here.
-- **(iii) full-all-models** — additionally create skeleton
-  `fcmae_vscyto3d_predict.yml`, `fnet3d_paper_predict.yml`,
-  `unext2_predict.yml` overlays. Defer unless needed.
+Remaining matrix:
+
+- Other organelles for `celldiff`: `mito`, `nucleus`, `membrane`.
+- Other models for `er`: `unetvit3d`, `fcmae_vscyto3d_{scratch,pretrained}`,
+  `fnet3d_paper`, `unext2`.
+- Cross-product: 4 organelles × 6 models = 24 cells (minus the one
+  already shipped).
+- Companion leaves per joint cell: `predict__ipsc_confocal.yml`,
+  `predict__a549_mantis.yml`, `eval__ipsc_confocal.yaml`,
+  `eval__a549_mantis.yaml`.
+
+Decision pending: order of expansion. Reasonable defaults are
+"finish the celldiff row first" (organelle sweep on a known-good
+model) or "finish the er column first" (model sweep on a known-good
+organelle). Pick when the next paper experiment lands.

-can proceed in parallel with Stages 1–3, as long as it lands before
-Stage 6.
-
-## Why not expand a549 first
-
-Tempting because the data work (Stage 5) is decoupled and a549
-experiments may be on the critical path for a paper. But writing a549
-leaves before the resolver means:
-
-- ~60 new YAMLs duplicate the paths the resolver will consolidate.
-- Eval target YAMLs get a549-variant clones, doubling the `target/`
-  group size (the thing Stage 4 is designed to shrink).
-- Every a549 leaf gets rewritten once the resolver lands, turning the
-  a549 PR into technical debt the moment it merges.
-
-If the research timeline forces Stage 5/6 before Stages 1–4 land, do it
-with eyes open: treat the hardcoded-path leaves as transitional and
-schedule the rewrite explicitly.
+Stages 1–3 and 5 (canonical) blocked Stage 6. The remaining gap on
+the VisCy side is the fixture mirror. Stage 7 has its own
+infrastructure (`BatchedConcatDataModule` + `ShardedDistributedSampler`)
+and is orthogonal to the resolver path.

-# VisCy PR Spec: Manifest-Driven Dataset Reference Resolution
-
-## Goal
-
-Add a resolver to VisCy's config composition pipeline that turns `benchmark.dataset_ref: {dataset, target}` into concrete `data_path`, `source_channel`, `target_channel` — read from a Pydantic `DatasetManifest` YAML discovered via manifest roots. Zero changes to Lightning CLI, Hydra, or `submit_benchmark_job.py`'s public surface. Backward compatible.
-
-## Context
-
-Today, core dataset facts are duplicated:
-
-- **dynacell-paper** `configs/datasets/aics-hipsc/manifest.yaml` — canonical source of truth (data paths, channels, spacing, splits).
-- **VisCy** `_internal/shared/model/{train_sets,targets}/*.yml` — hardcodes `data_path`, `source_channel`, `target_channel`.
-
-If a zarr store moves, both sides need hand updates. The intent hook `benchmark.dataset_group: aics-hipsc` already sits in `train_sets/ipsc_confocal.yml` as a breadcrumb — nothing reads it.
-
-This PR closes the gap by wiring a resolver at the composition choke point (`viscy_utils.cli._maybe_compose_config` plus `submit_benchmark_job.py`).
-
-## Non-goals
-
-- Eval-side (Hydra) resolution. Eval uses Pydantic manifests already via `pipeline_cache.py`; a follow-up PR can make eval leaves `dataset_ref`-aware.
-- Collection-aware data loading (Phase 5D of the dynacell-paper refactor). This PR resolves *dataset facts*, not *FOV membership*.
-- Inventing a new CLI flag surface on `dynacell fit` / `predict`. Resolution is implicit via the composition hook.
-- Importing anything from `dynacell-paper`. The resolver is generic.
-
-## New types and functions
-
-**`applications/dynacell/src/dynacell/data/manifests.py`** — add one Pydantic model:
-
-```python
-class DatasetRef(BaseModel):
-    """Reference to a dataset target, resolved against a manifest registry."""
-
-    dataset: str
-    target: str
-    # Future: override: dict = {} for paper-specific store swaps. Not in v1.
-```
-
-**`applications/dynacell/src/dynacell/data/resolver.py`** — new module:
-
-```python
-class ManifestNotFoundError(LookupError): ...
-class TargetNotFoundError(LookupError): ...
-class NoManifestRootsError(RuntimeError): ...
-
-class ResolvedDataset(BaseModel):
-    """Flat view of the fields a leaf needs after ref resolution."""
-
-    manifest_path: Path         # for provenance / logging
-    data_path_train: Path
-    data_path_test: Path
-    source_channel: str
-    target_channel: str
-    spacing: VoxelSpacing
-
-def discover_manifest_roots(
-    cli_roots: list[Path] | None = None,
-) -> list[Path]:
-    """Resolve manifest roots in precedence order (see below).
-
-    Raises NoManifestRootsError if nothing is configured.
-    """
-
-def resolve_dataset_ref(
-    ref: DatasetRef,
-    roots: list[Path] | None = None,
-) -> ResolvedDataset:
-    """Load the manifest for `ref.dataset` and return the target's fields."""
-```
-
-**Manifest root precedence** (highest wins):
-
-1. `cli_roots` parameter (from the compose hook).
-2. `DYNACELL_MANIFEST_ROOTS` env var (colon-separated absolute paths).
-3. Python entry points under group `dynacell.manifest_roots`; each entry resolves to a package resource directory (e.g. `dynacell_paper._configs.datasets`).
-
-Scan logic: for each root (in order), look for `<root>/<dataset>/manifest.yaml`. First hit wins. No recursion, no globbing.
-
-## Composition hook
-
-**`packages/viscy-utils/src/viscy_utils/compose.py`** — add an optional post-composition hook:
-
-```python
-def load_composed_config(
-    path: Path,
-    *,
-    resolver: Callable[[dict], dict] | None = None,
-) -> dict:
-    """... existing docstring ...
-
-    If `resolver` is provided, it is called on the final merged dict
-    before returning. Resolvers are pure: given a dict, return a dict.
-    """
-```
-
-Keep the existing behavior when `resolver` is `None`. No mutation of `_seen` semantics.
-
-**`packages/viscy-utils/src/viscy_utils/cli.py`** — `_maybe_compose_config`:
-
-```python
-# after load_composed_config(path) returns:
-composed = load_composed_config(path, resolver=_dynacell_ref_resolver)
-# existing: strip reserved keys (launcher, benchmark) before writing tempfile
-```
-
-The resolver:
-
-```python
-def _dynacell_ref_resolver(composed: dict) -> dict:
-    ref_dict = composed.get("benchmark", {}).get("dataset_ref")
-    if ref_dict is None:
-        return composed                     # no-op for legacy leaves
-    ref = DatasetRef.model_validate(ref_dict)
-    mode = _infer_mode(composed)            # "fit" | "predict" | "validate"
-    resolved = resolve_dataset_ref(ref)
-    return _splice_resolved(composed, resolved, mode)
-```
-
-### Mode inference (predict vs fit store)
-
-`_infer_mode(composed)` order:
-
-1. If `composed["launcher"]["mode"]` set (benchmark leaves always set this), use it.
-2. Else inspect `sys.argv[1]` (`fit` / `predict` / `validate`).
-
-Splicing:
-
-- `mode == "fit"` or `"validate"` → `data.init_args.data_path = resolved.data_path_train`
-- `mode == "predict"` → `data.init_args.data_path = resolved.data_path_test`
-- Always: `data.init_args.source_channel = resolved.source_channel`
-- Always: `data.init_args.target_channel = resolved.target_channel`
-
-`benchmark.spacing` gets filled from `resolved.spacing.as_list()` (handy for eval and any metric-aware callbacks). Since `benchmark:` is stripped before Lightning sees it, this only matters for downstream consumers of the resolved intermediate dict.
-
-### Collision policy
-
-If the composed config has BOTH `benchmark.dataset_ref` AND an explicit `data.init_args.data_path` (or `source_channel` / `target_channel`), raise `ValueError` with both values. Do not silently override either way — the user is giving conflicting signals and should pick.
-
-Exception: predict mode leaves sometimes declare `data.init_args.data_path` pointing at the test store today. Those leaves must migrate to `dataset_ref` in the same PR OR be left alone — they can't do both.
-
-### `submit_benchmark_job.py` pickup
-
-Since it calls `load_composed_config()` on line 159, the resolver is applied automatically — **but only if we pass it through**. Change that call to `load_composed_config(path, resolver=_dynacell_ref_resolver)`. The topology validation (gpus × nodes × ntasks_per_node) runs on the already-resolved dict, which is fine.

-  # drop source_channel
-```
-
-The viscy-utils changes stay generic (the `resolver` kwarg is a plain callable). The dynacell-specific resolver lives in `applications/dynacell/src/dynacell/_compose_hook.py` and is injected by dynacell's CLI entry points only. This keeps viscy-utils from depending on dynacell.
-
-## Test matrix
-
-**Unit (`test_dataset_ref.py`):**
-
-| Scenario | Expected |
-|---|---|
-| `resolve_dataset_ref` happy path (aics-hipsc/sec61b) | returns `ResolvedDataset` with correct paths |
-| unknown dataset | `ManifestNotFoundError` listing available datasets across roots |
-| unknown target within a known dataset | `TargetNotFoundError` listing available targets |
-| `DYNACELL_MANIFEST_ROOTS` unset + no entry points | `NoManifestRootsError` with install hint |
-| env var takes precedence over entry points | passes with env-var path |
-| invalid manifest YAML (missing `name`) | Pydantic `ValidationError`, file path in message |
-| `cli_roots` wins over env var and entry points | verified |
-
-**Integration (`test_benchmark_config_composition.py`):**
-
-| Scenario | Expected |
-|---|---|
-| `er/ipsc_confocal/celldiff/train.yml` composes with `dataset_ref` | resolved dict has `data_path_train`, correct channels |
-| same leaf with `launcher.mode: predict` swapped in | `data_path` resolves to test store |
-| leaf with `dataset_ref` + explicit `data_path` | `ValueError` on collision |
-| no `dataset_ref` in the composed config | resolver no-op; legacy path still works |
-| FCMAE pretrained/scratch parity | still only differs in encoder init |
-| topology invariants | still hold |
-
-**CLI routing (`test_cli_routing.py`):**
-
-- `dynacell fit -c <leaf>` → `_dynacell_ref_resolver` is wired into `load_composed_config`.
-- Hydra subcommands (`evaluate`, `report`, `precompute-gt`) — unchanged, no hook injected. (Eval-side is out of scope per "Non-goals".)
-
-**viscy-utils tests (`test_compose.py`):**
-
-- `load_composed_config` with `resolver=None` behaves exactly as before.
-- `resolver=lambda d: d` roundtrip identity.
-- `resolver` receives the post-merge dict, not per-base fragments.
-
-## Backward compatibility
-
-- Leaves with no `benchmark.dataset_ref`: unchanged behavior.
-- Leaves with explicit `data_path` and no `dataset_ref`: unchanged behavior.
-- The `compose.load_composed_config` signature gains a keyword-only arg with default `None`; existing callers are unaffected.
-- `viscy_utils` remains generic — it calls whatever resolver is passed, so other consumers can register their own.
-
-## Failure-mode messaging (explicit)
-
-Because the most common new failure will be "I ran `dynacell fit` and got an unhelpful error":
-
-```
-NoManifestRootsError: No dynacell manifest roots configured.
-
-Configure via one of:
-  - CLI flag:       --manifest-root /path/to/datasets
-  - Env var:        export DYNACELL_MANIFEST_ROOTS=/path/to/datasets
-  - Install a provider:  pip install dynacell-paper
-
-Leaf config at /path/to/leaf.yml references:
-  benchmark.dataset_ref: {dataset: aics-hipsc, target: sec61b}
-```
-
-```
-ManifestNotFoundError: dataset 'aics-hipsc' not found in manifest roots.
-
-Searched:
-  - /hpc/.../dynacell_paper/_configs/datasets     (no aics-hipsc/manifest.yaml)
-  - /tmp/my-roots                                 (no aics-hipsc/manifest.yaml)
-
-Available datasets across configured roots:
-  - (none)
-```
-
-## Migration plan (in-PR)
-
-1. Land the resolver + tests with all existing leaves untouched. Full test suite green.
-2. Migrate ONE target in the same PR: `er_sec61b.yml` + `ipsc_confocal.yml` — prove end-to-end composition produces an identical final dict to today (byte-for-byte if possible; modulo field ordering).
-3. Tail PRs (not this one) migrate `tomm20`, `membrane`, `nucleus`, and the mantis_lightsheet train_set when it lands.
-
-## Open questions for review
-
-1. **Should the resolver be part of viscy-utils, or purely in `applications/dynacell`?** This spec keeps the `resolver` kwarg in viscy-utils (generic) but the dynacell-specific resolver function in `applications/dynacell`. Alternative: promote the resolver concept as part of `viscy-utils`. I'd keep it generic (the viscy-utils kwarg takes any callable).
-2. **Entry point group name**: `dynacell.manifest_roots` is specific; `viscy.dataset_registries` is generic. Since the schema is dynacell-specific even though it lives in VisCy, I'd go with `dynacell.manifest_roots`.
-3. **Should `benchmark.dataset_ref` stay in the final dict (it gets stripped anyway) or get moved to a resolver-only key**? Staying under `benchmark:` is cleanest because it already gets stripped and has provenance value before strip. Keep it there.
-
-## Downstream (dynacell-paper) companion PR
-
-After this lands in VisCy, the dynacell-paper side change is small:
-
-1. Add the entry point in `pyproject.toml`:
-   ```toml
-   [project.entry-points."dynacell.manifest_roots"]
-   default = "dynacell_paper._configs.datasets"
-   ```
-2. Smoke test: `dynacell fit -c <VisCy leaf with dataset_ref> --trainer.fast_dev_run=true` resolves paths when `dynacell-paper` is installed.
-3. No changes to manifest YAML content.

-# FCMAE VSCyto3D training on Hopper — ~10× slowdown vs pre-Hopper GPUs
-
-## Summary
-
-Pretrained FCMAE VSCyto3D finetunes for iPSC SEC61B (job 31297032) and TOMM20
-(job 31375338) train at roughly ~75 s/step on H200, vs ~5 s/step on L40S under
-the same config + pretrained checkpoint. The slowdown is consistent across
-Hopper GPUs (H100 and H200) and is **not** fixed by switching precision
-(fp16-mixed → bf16-mixed).
-
-## Verdict (2026-04-25) — MS-DSSIM is the dominant slow term
-
-Direct per-step measurements from a Lightning-config probe that drops
-the MS-DSSIM term from the loss (T2: `MixedLoss(l1_alpha=1.0,
-ms_dssim_alpha=0.0)`), 4 GPUs on H100 (gpu-f-6), `SEC61B_test48.zarr`,
-otherwise identical to the prod config:
-
-| Step | data_wait_ms | compute_ms |
-| ---: | ---:         | ---:       |
-| 0    | 8198         | 16397 *(init / cuDNN autotune)* |
-| 1    | 583.7        | 929.3      |
-| 2    | 594.7        | 903.7      |
-| 3    | 700.0        | 891.2      |
-| 4    | 609.2        | 2958.2     |
-| 5    | 583.3        | 1416.1     |
-| 6    | 560.0        | 935.7      |
-| 7    | 555.2        | 1257.7     |
-| 8    | 555.8        | 1241.8     |
-| 9    | 548.1        | 1870.6     |
-
-Steady-state floor on rank 0 is ~0.9 s/step compute. The same prod config
-**with** MS-DSSIM measured **45.5 s/step compute** on identical N=4 H100
-hardware (Probe C job 31451180 and T5 job 31451960, 8 and 4 consecutive
-steady-state STEP_TIMER lines respectively) — a **~50× delta** attributable
-to the MS-DSSIM term.
-
-A symmetric MS-DSSIM-only probe (T4) was queued but cancelled when its
-StartTime slipped 8 hours; the deduction is closed by subtraction:
-L1-only is fast, L1+MS-DSSIM is slow, therefore MS-DSSIM is the slow
-term.
-
-### Fix landed (2026-04-25) — bf16 SSIM helper, 11× speedup confirmed
-
-The fix replaces monai's `compute_ssim_and_cs` with a precision-aware
-helper `_compute_ssim_and_cs_bf16` (commit `e42c49a`) and drops the
-now-redundant `@torch.amp.custom_fwd(cast_inputs=fp32)` decorator from
-`MixedLoss` and `SpotlightLoss` (commit `3a7fa05`). The helper runs the
-5 Gaussian-mean convolutions in bf16 (with squared products computed in
-fp32 before casting, to preserve squaring precision) and promotes only
-the variance subtractions and C₁/C₂-guarded divisions to fp32.
-
-T6 sanity probe (job 31453564, gpu-f-2 H100, N=4, MS-DSSIM enabled,
-`SEC61B_test48.zarr`, otherwise identical to T5/Probe C):
-
-| Step | data_wait_ms | compute_ms |
-| ---: | ---:         | ---:       |
-| 0    | 11894.6      | 15674.9 *(init / cuDNN autotune)* |
-| 1    | 542.1        | 4139.3     |
-| 2    | 535.8        | 4140.2     |
-| 3    | 538.7        | 4143.2     |
-| 4    | 548.5        | 4155.6     |
-| 5    | 542.4        | 4164.7     |
-| 6    | 541.1        | 4166.4     |
-
-Steady-state mean compute_ms: **4151 ms** over 6 consecutive lines
-(std ~10 ms). Versus the **45.5 s/step** baseline on identical N=4 H100
-hardware with fp32 MS-DSSIM (Probe C `31451180`, T5 `31451960`):
-**~10.97× speedup**.
-
-The remaining ~4 s/step is the actual MS-DSSIM compute cost on Hopper
-in the bf16 regime — an order of magnitude faster than fp32, but still
-meaningfully more than the 0.9 s/step L1-only floor (T2). Further
-mitigation (reducing pyramid depth, MS-DSSIM frequency) would attack
-that residual; not pursued here since 4 s/step is workable for FCMAE
-finetune training.
-
-Validated by tests in `packages/viscy-utils/tests/test_metrics.py`,
-`test_mixed_loss.py`, and the extended `test_spotlight_loss.py`. The
-contract holds at: per-pixel rtol=5e-2/atol=1e-1 (random), aggregate
-rtol=1e-2/atol=1e-2 (random), aggregate rtol=2e-3/atol=5e-3
-(correlated-pair), gradient cosine similarity ≥0.99, sign-flip
-fraction <1% on `|grad_ref|>1e-3` voxels.
-
-The earlier "Hopper kernel / DDP bucket-view stride mismatch" hypothesis
-(see [Earlier diagnosis](#earlier-diagnosis-superseded) below) is wrong as
-a cause — the stride warnings are real but not load-bearing for the
-slowdown. A plain Lightning + synthetic-data + DDP probe on N=4 H100
-(no MS-DSSIM, no real data pipeline) ran at 185.6 ms/step steady-state,
-ruling out Lightning, DDP, cuDNN, and the data pipeline as the
-bottleneck.
-
-### Why MS-DSSIM is slow on Hopper
-
-The MS-DSSIM 5-level pyramid runs in fp32 — at every level,
-`compute_ssim_and_cs` (monai) executes 5 large-kernel convolutions
-(μₓ, μᵧ, μₓₓ, μᵧᵧ, μₓᵧ) with a `(D=15, 11, 11)` kernel; the multiscale
-wrapper then `avg_pool3d`-downsamples and repeats 5 times. The
-conv-heavy core therefore runs in fp32 regardless of any outer
-mixed-precision context.
-
-What the **measurement** establishes: with that path skipped (T2),
-compute drops from 45.5 s/step → ~0.9 s/step on identical N=4 H100
-hardware. So fp32 MS-DSSIM is dominating on Hopper.
-
-What is **inferred but not directly measured**: that the gap is
-specifically explained by Hopper's bf16/fp16-vs-fp32 tensor-core
-advantage being larger than Ampere's / Ada's. Plausible from
-published kernel ratios, but we have not benchmarked the same monai
-SSIM kernels across architectures. The cross-architecture explanation
-should be treated as the leading theory, not an established fact.
-
-### Where the fp32 cast comes from (two stacked sources)
-
-1. **monai's `compute_ssim_and_cs`** (`monai/metrics/regression.py:402-403`)
-   force-casts both inputs to fp32 unconditionally:
-
-   ```python
-   y_pred = convert_data_type(y_pred, output_type=torch.Tensor, dtype=torch.float)[0]
-   y     = convert_data_type(y,      output_type=torch.Tensor, dtype=torch.float)[0]
-   ```
-
-   This is what makes MS-DSSIM slow on Hopper. The 25 conv ops (5 stats ×
-   5 pyramid levels) all run with fp32 weights and fp32 inputs.
-
-2. **viscy's `MixedLoss.forward`** (`packages/viscy-utils/.../mixed_loss.py:43`)
-   adds an outer `@torch.amp.custom_fwd(cast_inputs=torch.float32)`.
-   Introduced in commit `b4ec13c` (PR
-   [#37](https://github.com/mehta-lab/VisCy/pull/37), 2023-08-30), which
-   focused on the pixelshuffle decoder — the cast came in alongside
-   without a justifying note in the PR review. The mechanic of
-   `custom_fwd(cast_inputs=...)` is "cast the inputs and run the
-   forward with autocast disabled," so the decorator really does
-   create an fp32 island when active. The pattern is the well-known
-   "force MS-SSIM to fp32 to avoid NaN under autocast" workaround
-   (cf. torchmetrics issue
-   [#2281](https://github.com/Lightning-AI/torchmetrics/issues/2281):
-   `σ² = E[X²] − μ²` subtraction produces tiny negative values from
-   float deviations, the C₁/C₂ stability constants don't cover them,
-   resulting in NaN; later fixed upstream). This is corroborated by
-   the `clamp=True` flag in our `ms_ssim_25d`, documented as "for
-   training stability when used in loss" — author was already fighting
-   numerical instability.
-
-   Today this outer cast is **largely redundant**: the conv-heavy core
-   inside monai is already pinned to fp32, so removing the `@custom_fwd`
-   decorator only affects `F.l1_loss`, `F.mse_loss`, and the outer
-   `F.avg_pool3d` downsamplings — none of which are the slow path.
-   Removing it alone does **not** unblock Hopper.
-
-### Mitigation options (revised)
-
-The bottleneck is monai's internal fp32 cast on the SSIM convs, not
-viscy's outer decorator. Practical fallback order:
-
-1. **Local-patch monai's `compute_ssim_and_cs` with a mixed-precision
-   variant** — keep variance-sensitive math in fp32, run convs/pooling
-   in bf16:
-   - convs (μₓ, μᵧ, μₓₓ, μᵧᵧ, μₓᵧ) and `avg_pool3d` between levels:
-     **bf16** (kernels and inputs both)
-   - `mu_xx − mu_x*mu_x`, `mu_yy − mu_y*mu_y`, `mu_xy − mu_x*mu_y`:
-     **fp32**
-   - C₁/C₂-guarded divisions for `contrast_sensitivity` and `ssim`:
-     **fp32**
-
-   bf16 keeps fp32's 8-bit exponent (vs fp16's 5-bit), so it is the
-   right candidate for SSIM's near-equal subtraction; fp16 should be
-   avoided. Validate numerical equivalence against the current fp32
-   path on a representative batch before training.
-
-2. **Reduce MS-DSSIM frequency** — e.g. apply the MS-DSSIM term every
-   N steps and L1-only on the others. No precision changes; degrades
-   loss signal but doesn't risk numerical regression.
-
-3. **Drop MS-DSSIM entirely** on Hopper finetune runs. Largest
-   behavior change; should be backed by parity training runs against
-   the L1+MS-DSSIM baseline.
-
-### Fastest confirmation experiment
-
-Patch `compute_ssim_and_cs` so that:
-
-- it does **not** immediately cast `y_pred` and `y` to fp32,
-- the convs run under autocast (bf16 on Hopper),
-- only the variance subtraction and C₁/C₂-guarded divisions are
-  explicitly promoted to fp32.
-
-Re-run the T2-style sanity probe with MS-DSSIM **enabled** and this
-patched path. If step time collapses from ~45 s toward the L1-only
-~0.9 s regime, that load-bearing identification is confirmed.
-
-> **Note:** dropping only the `@torch.amp.custom_fwd` decorator from
-> `MixedLoss.forward` (without touching monai's internal cast) will
-> **not** restore Hopper throughput — the 25 fp32 convs in the pyramid
-> remain. This was an earlier mitigation suggestion that I retracted
-> after reading monai's source.

-## Throughput measurements
-
-All rows below use the same `fcmae.ckpt`-warm-started FCMAE VSCyto3D model,
-`ddp_find_unused_parameters_true`, 4 GPUs, `z=15, yx=256`, `num_samples=4`,
-`mmap_preload=true`, `scratch_dir=/dev/shm`.
-
-### Pretrained finetune sanity probes across architectures
-
-All probes use `SEC61B_test48.zarr` (48 FOVs), pretrained FCMAE VSCyto3D
-warm-start, 4 GPUs, fp16-mixed unless noted, 3 epochs.

-
-**The architecture split is sharp:** every pre-Hopper GPU runs at 2.8–5.1
-s/step. Every Hopper run we have measured (H100 fp16, H200 fp16, H200 bf16,
-scratch H100 fp16, scratch H100 bf16) lands in 46–75 s/step — a **13–27×
-slowdown** across the Hopper boundary regardless of precision, warm-start,
-or which Hopper SKU.
-
-The two A100 attempts both NCCL-timed out during a 32 M-element BROADCAST
-in DDP setup before any training step. That number matches the FCMAE
-encoder param count (32.1 M), so the symptom is consistent with rank 0
-being slow to load `fcmae.ckpt` (or otherwise blocked on rank-0-only I/O)
-while ranks 1–3 sat at the collective and the 30-min watchdog fired. This
-is an I/O coordination problem on those A100 nodes' shared-storage path,
-not a hardware fault — and not informative for the Hopper-vs-Ampere
-question. (Separate follow-up: rerun A100 sanity with rank 0 staging
-`fcmae.ckpt` before the DDP barrier, or measure raw read bandwidth from
-gpu-a-3 / gpu-d-2 to `/hpc/projects/virtual_staining`.)
-
-### Scratch-vs-pretrained × fp16-vs-bf16 controlled matrix (H100)
-
-To rule out the warm-start `ckpt_path` + `encoder_only: true` path and
-precision as the cause, we ran the same sanity harness with random init
-(no `ckpt_path`, no `encoder_only`) across both precisions on identical
-H100 hardware.
-
-| Init       | Precision   | GPU  | s/step | Source |
-| ---        | ---         | ---  | ---:   | --- |
-| Scratch    | fp16-mixed  | H100 | 46.57  | sanity job 31402627 (step 9→19 / 466 s) |
-| Scratch    | bf16-mixed  | H100 | 46.33  | sanity job 31402692 (step 9→19 / 463 s) |
-| Pretrained | fp16-mixed  | H100 | 47.60  | sanity job 31400433 (step 9→29 / 951 s) |
-| Pretrained | bf16-mixed  | H200 | 65.80  | sanity job 31400431 (step 9→19 / 658 s) |
-
-All four Hopper runs cluster in 46–66 s/step vs L40S 5.1 s/step. The
-slowdown is invariant to:
-
-1. Precision (fp16 ↔ bf16: 46.57 vs 46.33 on scratch — no difference).
-2. Warm-start (scratch ↔ pretrained on fp16: 46.57 vs 47.60 — no
-   difference).
-3. Hopper generation (H100 vs H200: both in the same band).
-
-**No config knob fixes this.** The slowdown is intrinsic to the FCMAE
-ConvNeXt graph hitting a slow Hopper kernel path.
-
-### Scratch FCMAE (prod runs, same architecture)

-| TOMM20  | L40S | Ada Lovelace | gpu-g-2 | 4.91 | 15 599 steps / 76 641 s (run 20260422-060655) |

-| SEC61B  | H200 | Hopper       | gpu-h-2 | —    | failed after ~46 min (missing resume ckpt) |
-
-**No FCMAE run (scratch or pretrained) has successfully reached steady-state

-pre-Hopper hardware (A40, L40S, A100 attempts).
-
-<a id="earlier-diagnosis-superseded"></a>
-## Earlier diagnosis (superseded by 2026-04-25 verdict above)
-
-The notes below were the working hypothesis before the L1-only probe
-showed compute time collapses 50× when MS-DSSIM is removed. They are
-left for the record — the cuDNN/DDP-stride warnings are real, but they
-are not the cause of the slowdown.
-
-- `py-spy dump` on live H200 rank 0 (prod SEC61B, job 31297032) pinned the
-  MainThread inside `_engine_run_backward` (`torch/autograd/graph.py:865`)
-  across 3 consecutive snapshots. DataLoader workers (`pt_data_worker`),
-  pin-memory loop, and wandb threads were all idle. → **bottleneck is
-  GPU-side backward(), not data loading.** (Consistent with verdict —
-  MS-DSSIM has a heavy backward.)
-- Hopper stderr consistently emits DDP warnings that don't appear on L40S:
-  - `AccumulateGrad node's stream does not match the stream of the node that
-    produced the incoming gradient` (pointing at DDP + stream ordering).
-  - `Grad strides do not match bucket view strides ... grad.sizes() = [240, 960, 1, 1],
-    strides() = [960, 1, 960, 960] vs bucket_view ... [960, 1, 1, 1]`
-    (pointing at a specific layer whose weight grad memory format breaks DDP's
-    bucket view contract on Hopper).
-- Switching `precision: bf16-mixed` on H200 changed throughput from ~75 → 65.8
-  s/step — basically the same order of magnitude. **Precision is not the
-  cause.**
-
-Earlier working hypothesis (now wrong): a specific kernel/layer (likely a
-pointwise 1×1 conv in the FCMAE ConvNeXt encoder given the `[240, 960, 1, 1]`
-weight shape) hits a slow Hopper path, and DDP can't fuse its grads cleanly
-due to the stride mismatch. **The L1-only probe falsified this** — with
-MS-DSSIM removed, that same encoder graph runs at ~0.9 s/step on H100,
-so the encoder is not the slow path.
-
-## OOM after ~20 h (separate, unresolved issue)
-
-These same 4-GPU jobs have also hit host-RAM OOM after **~20 hours of
-successful training**, even on datasets with ample nominal headroom (ER
-SEC61B is 80 GB compressed / 199 GB uncompressed on a 512 GB allocation).
-Because the kill happens deep into training and not at peak, this is a **slow
-host-RAM leak**, not a peak-sizing problem. Bumping `--mem=640G` just buys
-runway — it does not address the leak.
-
-Likely suspects (not yet instrumented):
-- Persistent DataLoader workers drifting via torch multiprocessing ref-count
-  leaks on forked COW pages.
-- `mmap_preload` + `/dev/shm` state not reclaimed across epochs.
-- A zarr chunk / pin-memory cache growing unbounded.
-
-Open TODO: log per-rank RSS at each epoch boundary in a production run and
-correlate with memory pressure signals to pin the actual source.
-
-## Recommendation
-
-1. **Done (commits `e42c49a` + `3a7fa05`):** local bf16 SSIM helper +
-   redundant decorator removal landed. Hopper FCMAE compute is now
-   ~4.15 s/step (T6 measurement) vs ~45.5 s/step before — within an
-   order of magnitude of L40S throughput.
-2. Future training runs (fresh starts, intentional checkpoint
-   migrations) can now target Hopper directly. Active prod runs on
-   A40/L40S (jobs 31415937, 31446584) should not be precision-flipped
-   mid-resume.
-3. Separately, add RSS instrumentation and investigate the 20 h host-RAM
-   leak; do not treat the `--mem=640G` bump as a fix.
-4. **Exclude A100 nodes for FCMAE training** via
-   `--constraint='h100|h200|a40|a6000|l40s'`. Two FCMAE scratch jobs
-   on A100 nodes (gpu-a-1, gpu-a-2) hit a ~30-min NCCL watchdog
-   timeout on the SeqNum-13 BROADCAST of the 32,148,528-element
-   encoder weights during DDP setup — same I/O coordination problem
-   that killed the earlier A100 sanity attempts. The bf16 fix doesn't
-   address this; it's an A100-shared-storage issue.
-
-## Final findings (2026-04-26) — bf16 fix shipped, 4-organelle benchmark in flight
-
-### Solution (one paragraph)
-
-The viscy-utils SSIM helper (`packages/viscy-utils/src/viscy_utils/
-evaluation/metrics.py`) replaces monai's fp32-pinned
-`compute_ssim_and_cs` with a precision-aware variant that runs the 5
-uniform-window mean convolutions in bf16 with squared products
-computed in fp32 *before* casting to bf16, and promotes only the
-variance subtractions and C₁/C₂-guarded divisions back to fp32.
-Redundant `@torch.amp.custom_fwd(cast_inputs=fp32)` decorators on
-`MixedLoss.forward` and `SpotlightLoss.forward` were removed in the
-same PR. Numerical contract is documented and tested with a 4-tier
-tolerance (per-pixel random, aggregate random, correlated-pair,
-gradient cosine + sign-flip) at ≥2× margin over measured drift. PR
-[#412](https://github.com/mehta-lab/VisCy/pull/412) merged as squash
-commit `48f4878`.

-Numbers come from wandb `loss/train_step` step×timestamp deltas with
-a `dt < 60s` filter (excludes ckpt-save / val / epoch-boundary
-insertions). All 8 jobs request `--mem=1024G` except the L40S baseline
-at 768G (CPU/RAM is not the driver). **All numbers will be re-pulled
-once the new Hopper jobs reach gstep ≥10k** — they are still in epoch
-0 (gstep < 1.7k) and warmup effects (DataLoader cache, mmap_preload,
-prefetch) likely inflate the per-step time. Steady-state from
-gstep ≥30k on A40/L40S is reliable.
-
-### What we can claim now
-
-- **Catastrophic Hopper slowdown is fixed.** Pre-fix Hopper measured
-  45–75 s/step; post-fix Hopper sits in 4.77–5.76 s/step — a 9–14×
-  recovery, within the same order of magnitude as L40S/A40.
-- **Hopper is now competitive but not visibly faster than L40S.** The
-  bf16 fix unblocks the catastrophic kernel cost but doesn't expose
-  a Hopper-specific tensor-core advantage in the end-to-end loop.
-- **A40 (gpu-c-1) is still the fastest measured path** at 2.40 s/step
-  steady-state. Likely drivers (not yet measured): node-local I/O for
-  zarr reads, /dev/shm topology, PCIe + CPU-worker layout. Same
-  shared-FS data path as Hopper, so the differentiator is on the
-  compute-node side.
-
-### What remains open
-
-- **Hopper steady-state vs warmup.** Will re-measure once new jobs
-  reach gstep ≥10k. Hopper might converge to ~A40 throughput once
-  caches warm, or may stay ~5 s/step (would suggest a stable
-  data-pipeline ceiling).
-- **A40 vs Hopper compute path.** No profiler / `iostat` /
-  `nvidia-smi dmon` data on either side. If Hopper steady-state stays
-  above ~3 s/step, a 5-min profiling probe on both nodes during
-  steady-state would isolate the bottleneck (data I/O vs GPU compute
-  vs DDP collective).
-- **20-hour host-RAM leak** still unresolved (separate thread, see
-  above). Independent of the bf16 fix.
-- **NCCL BROADCAST hang on A100** is a known I/O coordination issue
-  on those specific nodes' shared-storage path. Mitigation in place
-  (constraint OR-list); root cause not investigated.

-# Dynacell Job Submission — Reliability Plan
-
-Plan to close 3 gaps in `applications/dynacell/tools/submit_benchmark_job.py` +
-`sbatch_template.sbatch` exposed by the 2026-04-21 NCCL hangs on `gpu-d-1`
-(4 sibling FCMAE jobs wasted ~1 h each on a 30-min NCCL watchdog timeout
-before aborting).
-
-**Scope (v2.4):** Gap 1 + Gap 3 only. Gap 2 (auto-requeue on NCCL watchdog
-hang) is **deferred** — plan preserved below for future pickup, but not
-implemented this round. Files touched this round: `submit_benchmark_job.py`,
-`sbatch_template.sbatch`, new `nccl_smoke_test.py`, and the test file. No
-behavior change for jobs that run cleanly.
-
-**v2.4 — updated 2026-04-21 after deferring Gap 2.** Changes listed in
-[Appendix: Review findings addressed](#appendix-review-findings-addressed).
-
----
-
-## Gap 1 — `--exclude` as optional SBATCH directive
-
-**Decision:** mirror how `constraint` is handled. `exclude` is optional,
-renders as `--exclude=<value>` when set, skipped when null/absent.
-
-**Changes to `applications/dynacell/tools/submit_benchmark_job.py`:**
-
-```python
-_SBATCH_DIRECTIVE_ORDER = (
-    ("job_name", "--job-name"),
-    ("time", "--time"),
-    ("nodes", "--nodes"),
-    ("ntasks_per_node", "--ntasks-per-node"),
-    ("partition", "--partition"),
-    ("cpus_per_task", "--cpus-per-task"),
-    ("gpus", "--gpus"),
-    ("mem", "--mem"),
-    ("constraint", "--constraint"),
-    ("exclude", "--exclude"),     # NEW
-)
-
-_OPTIONAL_SBATCH_DIRECTIVES = frozenset({"constraint", "exclude"})
-```
-
-Rendering already handles null via `_OPTIONAL_SBATCH_DIRECTIVES`; the
-`--constraint` quoting branch stays as-is (don't quote `--exclude`, SLURM
-accepts bare comma-separated hostlists).
-
-**Usage** — either set in a profile, in the leaf, or via `--override`:
-
-```sh
-uv run python .../submit_benchmark_job.py <leaf.yml> \
-    --override launcher.sbatch.exclude=gpu-d-1
-```
-
-**Tests** (extend `applications/dynacell/tests/test_submit_benchmark_job.py`):
-
-- `exclude="gpu-d-1"` → rendered output contains `#SBATCH --exclude=gpu-d-1`
-  and this line appears after `#SBATCH --constraint=...` and before
-  `#SBATCH --output=...` (content-based, not positional `[-1]`).
-- `exclude=None` or absent → no `--exclude` substring in rendered output.
-- Use content-based assertions (`"--exclude=" in rendered`, line-search) so
-  future optional directives don't break the test.
-
-**Verify:**
-`uv run pytest applications/dynacell/tests/test_submit_benchmark_job.py -k exclude`

-## Gap 2 — auto-requeue on NCCL watchdog hang [DEFERRED]
-
-> **DEFERRED in v2.4.** Not implementing this round. The full plan below is
-> preserved as-is (four rounds of review) so it can be picked up later without
-> re-derivation. Implementing Gap 1 + Gap 3 alone still closes the motivating
-> failure mode: Gap 3's preflight kills bad-node jobs in ~60 s instead of
-> burning a 30-min NCCL watchdog, and Gap 1 lets the operator add
-> `--exclude=gpu-d-1` on the manual resubmit. The `#SBATCH --requeue`
-> directive and all shell shared-vars (ERR_LOG / BAD_LIST / COUNTER_FILE /
-> PREFLIGHT_MARKER / MAX_REQUEUE) are **not** added to the template in v2.4
-> — they only exist to serve the requeue path below.
-
-**Decisions:**
-
-1. **Single-node only.** Guard on `$SLURM_JOB_NUM_NODES -eq 1`. On
-   multi-node jobs, exit with the original rc — no auto-requeue. Our hardware
-   profiles are all `nodes: 1` today; when/if a multi-node profile lands, the
-   bad-node identification strategy must be revisited (parse the `[Rank N]`
-   hostname from the watchdog stderr line).
-2. **Trust `$SLURM_JOB_NODELIST`**, not `squeue`. It's set at allocation time,
-   stable across state transitions, and matches a single hostname on
-   single-node jobs.
-3. **Counter in a file under `run_root/slurm/`**, keyed on `$SLURM_JOB_ID`.
-   `SLURM_RESTART_COUNT` is unreliable across `scontrol requeue` — some Slurm
-   configs don't increment it on manual requeues.
-4. **Disable the EXIT trap before `scontrol requeue`.** Requeued jobs keep
-   the same `$SLURM_JOB_ID`, so the existing trap's
-   `rm -rf /dev/shm/$SLURM_JOB_ID` would wipe the mmap preload cache that the
-   requeued run expects to reuse (`scratch_dir: /dev/shm`, `mmap_preload:
-   true` in the ipsc_confocal train set).
-5. **Use `scontrol requeuehold` → `update ExcNodeList` → `release`**, not
-   `update` on a RUNNING job. Some Slurm versions reject `ExcNodeList` updates
-   while the job is RUNNING. Requeuehold parks the job in held-pending,
-   guaranteeing the update applies before scheduling.
-6. **Record preflight failures in a separate marker file**, not the Slurm
-   stderr. Writing to `%j.err` races with slurmstepd, and pollutes the user's
-   error log.
-
-**Changes to `applications/dynacell/tools/sbatch_template.sbatch`:**
-
-Add `#SBATCH --requeue` as a **literal line directly in the template**,
-immediately after the `@@sbatch_directives` substitution line. `--requeue` is
-valueless and always-on for dynacell jobs (no per-leaf configurability), so
-it belongs in the template next to the other always-on scaffolding (`umask
-0002`, `ml uv`, cleanup trap) — not routed through
-`_render_sbatch_directives()`, which only emits keyed directives from
-`_SBATCH_DIRECTIVE_ORDER`.
-
-Concretely, the top of the template becomes:
-
-```bash
-#!/bin/bash
-
-@@sbatch_directives
-#SBATCH --requeue
-```
-
-**No change to `submit_benchmark_job.py` for the `--requeue` directive.**
-`_SBATCH_DIRECTIVE_ORDER` stays keyed-only. If we ever need another valueless
-SBATCH directive, we can either add another literal line or extend the

-
-**Assumption to verify before shipping Gap 2:** on our Slurm install,
-`scontrol requeuehold` + `update ExcNodeList` + `release` reliably applies
-the exclusion to the next run. Probe once with a dummy job before enabling
-this path. If the probe fails, fall back to appending to `bad_nodes.log` only
-and require operator resubmit (Gap 1 unblocks this fallback).
-
-**Verify:** dry-render the template (`--print-script` on a known leaf), diff
-against the previous version; ensure the main srun line, cleanup trap, and
-`@@resolved_config` substitution are intact.

-## Gap 3 — pre-flight NCCL smoke test
-
-**Decisions:**
-
-1. **Absolute path to the smoke test**, injected via a new `@@repo_root`
-   template substitution. The rendered sbatch does not `cd` and sbatch is
-   submitted from arbitrary CWDs — relative paths break.
-2. **Map Slurm env vars to torch.distributed env vars in the Python script**,
-   not the shell. Slurm sets `SLURM_PROCID`, `SLURM_NTASKS`, `SLURM_LOCALID`;
-   `torch.distributed.init_process_group(backend="nccl", init_method="env://")`
-   needs `RANK`, `WORLD_SIZE`, `LOCAL_RANK`. Doing the mapping in Python keeps
-   the template slim and testable.
-3. **Per-job deterministic `MASTER_PORT`** derived from `$SLURM_JOB_ID`, same
-   pattern Lightning's `SLURMEnvironment` uses — avoids collisions when two
-   jobs share a host.
-4. **Unset `MASTER_ADDR`/`MASTER_PORT` before the main srun** so Lightning's
-   SLURMEnvironment can set them itself without inheriting preflight values.
-5. **Preflight failure exits the script immediately** (v2.4). With Gap 2
-   deferred, there is no marker file and no auto-requeue — the job fails with
-   the smoke-test's non-zero rc, and the operator resubmits manually (using
-   `--override launcher.sbatch.exclude=...` from Gap 1 if needed). If/when
-   Gap 2 is picked up, swap `exit $SMOKE_RC` for `touch "$PREFLIGHT_MARKER";
-   SRUN_RC=$SMOKE_RC` so the requeue decision block downstream can handle it.
-
-**Submitter changes** — `applications/dynacell/tools/submit_benchmark_job.py`
-around the current `SbatchTemplate(...).substitute(...)` call:
-
-```python
-repo_root = Path(__file__).resolve().parents[3]  # VisCy/
-
-rendered = SbatchTemplate(template_text).substitute(
-    sbatch_directives=_render_sbatch_directives(job_name, str(run_root), sbatch),
-    run_root=str(run_root),
-    env_block=_render_env_block(env),
-    mode=mode,
-    resolved_config=str(resolved_path),
-    repo_root=str(repo_root),     # NEW
-)
-```
-
-**New file `applications/dynacell/tools/nccl_smoke_test.py`:**
-
-```python
-"""60-second NCCL all-reduce smoke test for dynacell training preflight.
-
-Maps Slurm's per-task env vars (SLURM_PROCID, SLURM_NTASKS, SLURM_LOCALID) to
-the env:// init variables torch.distributed expects (RANK, WORLD_SIZE,
-LOCAL_RANK), then runs a single all_reduce + barrier with a 60-second init
-timeout. Exits non-zero (via unhandled RuntimeError, which is the intended
-signal per project "prefer raising errors" policy) on hang or any NCCL error.
-"""
-

-
-**Template preflight block** — inserted **before** the existing
-`srun uv run python -m dynacell ...` line (no shared-vars prerequisite in
-v2.4 since Gap 2 is deferred):
-
-```bash
-export MASTER_ADDR=$(scontrol show hostnames $SLURM_JOB_NODELIST | head -n1)
-export MASTER_PORT=$((15000 + SLURM_JOB_ID % 20000))
-
-echo "[preflight] NCCL smoke test..."
-srun --kill-on-bad-exit=1 uv run python @@repo_root/applications/dynacell/tools/nccl_smoke_test.py
-SMOKE_RC=$?
-if [ $SMOKE_RC -ne 0 ]; then
-    echo "[preflight] smoke test FAILED on $SLURM_JOB_NODELIST (rc=$SMOKE_RC); exiting before main srun" >&2
-    exit $SMOKE_RC
-fi
-
-# Lightning's SLURMEnvironment picks its own port from SLURM_JOB_ID; don't
-# leak the preflight values into the training srun.
-unset MASTER_ADDR MASTER_PORT
-```
-
-`exit $SMOKE_RC` fires the cleanup trap (unchanged from the current
-template), so `/tmp/$SLURM_JOB_ID` and `/dev/shm/$SLURM_JOB_ID` are cleaned
-up on preflight failure just like any other exit path.
-
-**Verify:** allocate an interactive session first so `SLURM_JOB_ID` is set
-(lets us derive `MASTER_PORT` the same way the template does — no
-hardcoded port):
-
-```sh
-salloc --nodes=1 --ntasks=4 --gpus=4 --time=00:10:00
-# inside the allocation:
-export MASTER_ADDR=$(hostname)
-export MASTER_PORT=$((15000 + SLURM_JOB_ID % 20000))
-srun uv run python /hpc/mydata/alex.kalinin/VisCy/applications/dynacell/tools/nccl_smoke_test.py
-```
-
-Should print `[nccl-smoke] OK world_size=4 sum=4.0` in <10 s. Without
-`MASTER_ADDR`/`MASTER_PORT`, `torch.distributed.init_process_group` with
-`init_method="env://"` (the default) will error out — the template exports
-them, so this manual command must too. The derive-from-`SLURM_JOB_ID` port
-formula matches the template exactly.
-
----
-
-## Tests — expanded scope
-
-No existing test needs rewriting in v2.4. With Gap 2 deferred, the main
-dynacell `srun ...` line remains the last line of the rendered template
-(Gap 3's preflight srun is inserted *before* it), so
-`test_rendered_sbatch_has_srun_at_expected_resolved_path` keeps passing
-unchanged. `test_render_sbatch_directives_matches_dihan_order` is also
-unaffected (exclude only appears when set; default leaves leave it absent).
-
-New tests to add in
-`applications/dynacell/tests/test_submit_benchmark_job.py`:
-
-- `test_rendered_sbatch_has_preflight_srun_absolute_path` — preflight
-  `srun ...nccl_smoke_test.py` line references an absolute path rooted at
-  the repo (no bare `applications/...`).
-- `test_exclude_directive_rendered_when_set` — sbatch dict with
-  `exclude="gpu-d-1"` produces `#SBATCH --exclude=gpu-d-1`.
-- `test_exclude_directive_skipped_when_absent` — absent or `None` → no
-  `--exclude` substring.
-- `test_repo_root_substituted_in_preflight_path` — rendered preflight srun
-  contains the absolute repo-root path (assert starts with `/` and ends with
-  `/applications/dynacell/tools/nccl_smoke_test.py`).
-- `test_preflight_failure_exits_before_main_srun` — rendered template
-  contains `exit $SMOKE_RC` on the preflight-failure branch, ahead of the
-  main dynacell srun.
-
----
-
-## Order of execution & risk
-
-1. **Gap 1 first, stand-alone commit.** Lowest risk. Unblocks today's
-   resubmits via `--override launcher.sbatch.exclude=...`. Tests: 2 new cases.
-2. **Gap 3 second** (smoke test file + template preflight wrapper + submitter
-   `repo_root` substitution). Moderate risk: template change, new Python
-   module. Verify: dry-render + diff rendered sbatch; run the smoke test on
-   a 4-GPU interactive allocation before enabling preflight for benchmark
-   submissions.
-3. **Gap 2 deferred.** Not shipped this round. See the Gap 2 section for the
-   full design; pick up later after a Slurm `requeuehold/update/release`
-   probe confirms the sequence works on our cluster.
-
----
-
-## Out of scope
-
-- **Gap 2 (auto-requeue on NCCL watchdog hang) — deferred in v2.4.** Plan
-  preserved above for pickup after a Slurm `requeuehold/update/release`
-  probe. Gap 1 + Gap 3 together close the motivating GPU-hour loss (bad
-  nodes fail fast in preflight; operator resubmits with `--exclude`), so
-  Gap 2's incremental value is automation-only, not correctness.
-- Pattern divergence with
-  `applications/dynaclr/configs/training/slurm/train.sh` (the 4th gap from
-  the original review). Fix here stays dynacell-local; revisit
-  cross-application unification separately if the same NCCL-hang failure
-  mode appears in dynaclr runs.
-- Multi-node auto-requeue. Explicitly guarded off by
-  `SLURM_JOB_NUM_NODES -eq 1` in the deferred Gap 2 design. Revisit when a
-  multi-node hardware profile lands.
-
----
-
-## Appendix: Review findings addressed
-
-Plan stress-tested by 3 internal subagents (correctness, regression, merge
-compatibility) + external review. Changes from v1:
-
-### Blocking (addressed)
-
-- **Smoke-test script path was repo-relative.** v1 ran
-  `uv run python applications/dynacell/tools/nccl_smoke_test.py` under a
-  sbatch script that never `cd`'s. v2: inject `@@repo_root` substitution in
-  submitter; template uses absolute path.
-- **Smoke test missed `RANK`/`WORLD_SIZE`.** v1's `init_process_group` relied
-  on `env://` default but only exported `MASTER_ADDR`/`MASTER_PORT`. Slurm
-  sets `SLURM_PROCID`/`SLURM_NTASKS`, not `RANK`/`WORLD_SIZE`. v2: map in
-  Python via `os.environ.setdefault`.
-- **Existing test asserts the tail is a single srun line.** v1 only planned
-  `exclude` test additions. v2: explicit rewrite of
-  `test_rendered_sbatch_has_srun_at_expected_resolved_path` to content-based
-  assertion, plus 5 new tests for `--requeue`, preflight, requeue block,
-  exclude on/off, and repo-root substitution.
-
-### Important (addressed)
-
-- **`squeue -o %N` for multi-node jobs.** v2 guards on
-  `SLURM_JOB_NUM_NODES -eq 1` and uses `$SLURM_JOB_NODELIST` directly.
-- **`SLURM_RESTART_COUNT` unreliable on manual requeue.** v2 uses a
-  file-backed counter keyed on `SLURM_JOB_ID`.
-- **`scontrol update ExcNodeList` may be rejected on RUNNING jobs.** v2 uses
-  `requeuehold` → `update` → `release` sequence.
-- **Cleanup trap wipes `/dev/shm/$SLURM_JOB_ID` on manual requeue** (same
-  jobid reused → mmap cache lost). v2: `trap - EXIT` before `scontrol requeue`.
-- **Preflight failure writing synthetic marker into `$ERR_LOG`** races with
-  slurmstepd + pollutes user's error log. v2: separate `PREFLIGHT_MARKER`
-  file, Gap 2 checks both marker and stderr grep.
-- **`MASTER_PORT=29500` hardcoded.** v2: derive from `SLURM_JOB_ID` (same
-  pattern as Lightning's `SLURMEnvironment`).
-- **`MASTER_PORT` leaking to main srun** would override Lightning's
-  auto-picked port. v2: `unset MASTER_ADDR MASTER_PORT` after preflight.
-- **Variable ordering (Gap 2 vars referenced by Gap 3 preflight).** v2:
-  declare `ERR_LOG`/`PREFLIGHT_MARKER`/`COUNTER_FILE`/`BAD_LIST` in a shared
-  top-of-script block before both preflight and main srun.
-
-### Additional review pass (external, after v2 draft) → v2.1
-
-- **Requeue path was best-effort with unconditional `exit 0`.** Any failure
-  in the `scontrol requeuehold/update/release` trio would silently mask a
-  real failed training run as a green job, or requeue without the exclusion
-  actually applied. v2.1: chained `if scontrol ... && scontrol ... && scontrol
-  ... ; then exit 0 ; fi` — on any scontrol failure, fall through to
-  `exit $SRUN_RC` so the job stays visibly failed in Slurm accounting.
-- **Standalone smoke-test verify command was incomplete.** It relied on
-  `env://` init but didn't export `MASTER_ADDR`/`MASTER_PORT`, and used a
-  repo-relative script path. v2.1: verify command now exports both env vars
-  and invokes the script by absolute path, matching the rendered template.
-
-### Scope change → v2.4
-
-- **Gap 2 deferred.** User decision to ship Gap 1 + Gap 3 only this round.
-  Gap 2 section preserved intact (four rounds of review still valid for
-  future pickup), but marked `[DEFERRED]`.
-- **Gap 3 preflight simplified** from "touch marker and let Gap 2 handle it"
-  to fail-fast `exit $SMOKE_RC`. Cleanup trap handles tmp/shm on the exit
-  path — no leak.
-- **Shared-vars block dropped.** `ERR_LOG` / `BAD_LIST` / `COUNTER_FILE` /
-  `PREFLIGHT_MARKER` / `MAX_REQUEUE` only existed to serve the deferred
-  requeue decision block.
-- **`#SBATCH --requeue` dropped.** It was paired with Gap 2's manual requeue;
-  without that, it only covers Slurm-side NODE_FAIL / preempt, which is out
-  of the motivating scope (NCCL hangs don't trigger `--requeue`).
-- **Two planned tests dropped.** `test_rendered_sbatch_has_requeue_directive`
-  and `test_rendered_sbatch_has_requeue_block` — both exercised Gap 2
-  artifacts that no longer render.
-- **Existing test rewrite dropped.**
-  `test_rendered_sbatch_has_srun_at_expected_resolved_path` uses
-  `rendered.splitlines()[-1]`, which still works: Gap 3's preflight srun is
-  inserted *before* the main dynacell srun, so the dynacell srun remains the
-  last line of the rendered template.
-
-### Fourth external review pass → v2.3
-
-- **`#SBATCH --requeue` emission path was underspecified.** v2.2 said the
-  directive "flows through `@@sbatch_directives` substitution — handled at
-  render time", but `_render_sbatch_directives()` only emits keyed directives
-  from `_SBATCH_DIRECTIVE_ORDER` (key + value pairs) plus `--output`/`--error`
-  — there is no code path for a bare valueless directive. Implementing the
-  plan as written would have produced a rendered sbatch with no `--requeue`
-  line, silently disabling the Slurm-side auto-requeue Gap 2 depends on.
-  v2.3: `#SBATCH --requeue` is a literal line in `sbatch_template.sbatch`
-  directly after `@@sbatch_directives` (same pattern as `umask 0002`, `ml
-  uv`, cleanup trap — always-on scaffolding belongs in the template). No
-  submitter change; `_SBATCH_DIRECTIVE_ORDER` stays keyed-only. Test
-  `test_rendered_sbatch_has_requeue_directive` is unaffected (content-based).
-
-### Third external review pass → v2.2
-
-- **Held-pending leak on partial scontrol failure.** v2.1's `&&` chain
-  (`requeuehold && update && release`) short-circuits: if `requeuehold`
-  succeeds but `update` fails, `release` never runs and the job stays stuck
-  in held-pending. v2.2: explicit state machine — if `requeuehold` returns
-  0, always attempt `release` before exiting, even on subsequent failures;
-  warn the operator if `release` itself fails (manual recovery needed).
-  `REQUEUE_OK=1` gates the `exit 0` so a successful-hold-but-failed-update
-  path can't report green.
-- **Cleanup leaked on non-requeued failure path.** `trap - EXIT` was
-  disabled unconditionally before scontrol, so on any scontrol failure the
-  job exited `$SRUN_RC` without running cleanup, leaking
-  `/tmp/$SLURM_JOB_ID` and `/dev/shm/$SLURM_JOB_ID`. v2.2: call `cleanup`
-  explicitly before `exit $SRUN_RC` on the scontrol-failure branch. The
-  normal-failure branch (SHOULD_REQUEUE=0) still has the EXIT trap intact,
-  so cleanup runs there unchanged.
-- **Manual verify command hardcoded `MASTER_PORT=29500`.** v2.2: switched to
-  `salloc` + `export MASTER_PORT=$((15000 + SLURM_JOB_ID % 20000))`,
-  matching the template's per-job-id derivation. No fixed-port footguns.
-
-### Nitpicks (not adopted)
-
-- Gratuitous `set -e`/`set +e` toggles — v2 avoids them entirely by letting
-  the original un-errexit'd shell semantics hold. Strict error checking is
-  scoped only to the scontrol trio (v2.1), where it matters for correctness.
-- Grep regex brittleness for watchdog signature — current `"Watchdog caught
-  collective operation timeout"` is the stable c10d message; accept
-  brittleness to PyTorch upgrades (noisy upgrade will be caught by
-  preflight, not the post-hoc grep).
-- `BAD_LIST` collision across leaves — each leaf's `run_root` is unique;
-  scope by `$SLURM_JOB_ID` in the filename belt-and-suspenders.
-
-### Positive findings (no action)
-
-- No merge conflicts with `main` or other open PRs; all three files this
-  plan touches are only edited on `dynacell-models` and only by prior
-  commits, not in-flight work.
-- Hardware profile YAMLs don't need parallel edits — `exclude` flows through
-  `--override launcher.sbatch.exclude=...` without requiring a profile
-  change.

Subject: [PATCH 209/311] chore(dynacell): rename ER+Mito FCMAE pretrained
 outputs to _ws8500

The original ER and Mito FCMAE pretrained leaves predated the
warmup_steps=8500 model overlay (commit d296c7f, 2026-04-23) and
were submitted with the engine default warmup_steps=3, while their
scratch counterparts ran with warmup_steps=8500. To make the
pretrained vs scratch pairs directly comparable on training
protocol, rename outputs to a sibling _ws8500 directory so both
the abandoned ws=3 baselines and the new ws=8500 runs coexist on
disk. README.md files in the parent dirs document the dual-dir
layout.

Subject: [PATCH 210/311] chore(dynacell): pin compute-job CWD to repo_root in
 sbatch template

Lets the dynacell launcher work from a git worktree: uv resolves
project context (pyproject + .venv) from CWD, so without an
explicit cd the compute-node srun would inherit whatever CWD sbatch
was invoked from and may pick up the wrong worktree's environment.
Pinning to @@repo_root (the worktree containing the launcher
script) makes the env deterministic regardless of submit-side CWD.

Subject: [PATCH 211/311] docs(dynacell): refresh A549 roadmap with 2026-04-24
 status

Stage 5 (a549 manifest): A549 zarr normalization-stats backfill
closed 2026-04-24 in dynacell-paper (f4120e0 + 17-zarr backfill);
no VisCy-side action remaining for that subtask.

Stage 7 (joint training leaves): mark "in flight - blocked". PR #413
(0b04b24) closed one DDP deadlock surface but the 4-GPU smoke
(234819a) still hangs at the same milestone; a second deadlock
surface remains. Joint leaf expansion is paused until that resolves.
Cross-reference the followup handoff and the _test48 debug-zarr
convention for short-wall smoke runs.

Subject: [PATCH 212/311] fix(dynacell): repoint mito A549 cross-eval to
 2024_11_21 plate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 2024_10_29 plate the Stage 6 mito leaves were wired to is
train-only by design — its splits author 0 test FOVs. Repoint the
fixture mirror, predict_set fragments (model + Hydra side), the four
mito predict/eval leaves, and the two test matrices to
a549-mantis-2024_11_21, which has 11 authored test FOVs.

This unblocks all 8 Stage 6 cross-eval cells; ER, mito, nucleus, and
membrane × {celldiff, unetvit3d} now point at plates with real test
splits on disk.

Subject: [PATCH 213/311] feat(dynacell): add fnet3d_paper Stage 6 A549 predict
 leaves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Author 4 a549_mantis predict leaves for fnet3d_paper × {er, mito,
nucleus, membrane}, mirroring the iPSC fnet predict leaves. Plates
follow the same wiring used by celldiff/unetvit3d a549 leaves: ER/
sec61b → 2024_11_07, mito/tomm20 → 2024_11_21, nucleus and membrane
→ 2026_03_26 (with benchmark.dataset_ref.target overrides h2b and
caax for the gene-keyed a549 targets). Each leaf reuses the same
iPSC best-val checkpoint as predict__ipsc_confocal.yml — Stage 6 is
cross-eval, not retrain.

This rounds out the third and final model row for Stage 6's
"full-but-predictable-only" sub-scope (celldiff + unetvit3d already
landed in #415; fnet3d_paper completes the trio).

Subject: [PATCH 214/311] feat(dynacell): add fcmae_vscyto3d Stage 6 A549
 predict scaffolding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a shared `fcmae_vscyto3d_predict.yml` overlay (mirrors the model
block from `fcmae_vscyto3d_fit.yml` so checkpoints load with the
matching architecture, plus predict-time hparams) and 8 a549_mantis
predict leaves: 4 organelles × {pretrained, scratch}. Plates follow
the same wiring as the celldiff/unetvit3d/fnet3d_paper a549 leaves
(ER/sec61b → 2024_11_07, mito/tomm20 → 2024_11_21, nucleus/h2b and
membrane/caax → 2026_03_26 with `dataset_ref.target` overrides).

`ckpt_path` is intentionally a `/TODO_FILL_BEFORE_SUBMIT/...` path
on every leaf — iPSC FCMAE training is still in flight (jobs
31475094-31523064). Submitting any of these as-is will fail loudly
with FileNotFoundError on torch.load. Each leaf header documents the
expected post-training path so the swap is mechanical.

Note: ER + Mito pretrained outputs use a `_ws8500` warmup-steps
suffix (per commit 9af8bdf); nucleus + membrane pretrained do not.
Suggested paths in the headers reflect that asymmetry.

Subject: [PATCH 215/311] feat(dynacell): add FNet3D ER joint single-GPU smoke
 leaf
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Author the FNet3D counterpart to the existing celldiff
joint_ipsc_confocal_a549_mantis/train_smoke.yml. Pairs the iPSC
SEC61B_test12 zarr (12 FOVs, 2.4 GB) with the 4-FOV a549_mantis
SEC61B store so a single A40 / H200 can iterate the joint loader
end-to-end without the full ~250 GB iPSC SEC61B mmap_preload wait.

Verified end-to-end on a local A40: 10 fwd+bwd+optim steps in 1:19,
26 GB peak GPU mem, loss/train_step 0.680 → 1.187 epoch loss, three
checkpoints written. Joint sharding on FNet3D's 35.3 M-param model
with z=32 / yx=64 / bs=8 fp32 works at single-GPU.

Note: leaf bakes `num_workers: 0` + `pin_memory: false` because the
default `num_workers > 0` + `pin_memory: True` reliably hangs on
forking the dataloader workers from a CUDA-initialized parent on
this cluster's interactive nodes (same pattern as the 4-GPU joint
smoke deadlock). Header documents the workaround so consumers tune
up only when they need throughput.

Subject: [PATCH 216/311] perf(cytoland): enable mmap+persistent+bf16 for A549
 infected finetune

Three flips to maximize throughput on the 4xH200 prod run now that PR #411
lifted the mmap_preload + exclude_fov_names restriction:

  - persistent_workers: true on the 3 sub-DMs avoids the worker re-spawn
    cost that dominated dynacell's per-epoch overhead.
  - mmap_preload: true caches each plate to local /tmp scratch (28 TB on
    H200 nodes), eliminating per-batch NFS reads. D3 now mmaps cleanly
    even with its 27 exclude_fov_names entries thanks to PR #411.
  - precision: bf16-mixed dodges the Hopper fp16 cuDNN slowdown
    documented in applications/dynacell/configs/examples/fcmae_hopper_slowdown.md.

D2 smoke explicitly overrides both DataModule flags to false so
single-GPU smokes on the full prod plate stay under their walltime;
the bf16 flip is kept on the smoke to validate the AMP path.

Subject: [PATCH 217/311] chore(cytoland): drop h200 constraint on A549
 infected sbatch

The 4xH200 slot was scheduling 5 days out. bf16-mixed (landed in
ad1df84) avoids the Hopper fp16 slowdown that was the original
reason to pin to H200, so any 4-GPU node (H100/A100/A6000) is fine
and starts much sooner.

Subject: [PATCH 218/311] feat(dynacell): bundle manifest registry as
 first-class package data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Promote the test fixture manifest mirror to a real registry shipped with
the dynacell wheel. The resolver auto-discovers it via the
``dynacell.manifest_roots`` entry point declared in pyproject.toml, so a
fresh clone resolves ``benchmark.dataset_ref`` lookups out of the box —
no ``DYNACELL_MANIFEST_ROOTS`` env var needed for predict/eval/test runs.

Replaces the previous workaround where users had to either set the env
var manually (multiple sessions hit ``ManifestNotFoundError`` because of
this) or rely on the autouse pytest fixture that injected it for tests
only. The env var stays as an explicit override path for testing
discovery precedence.

Splits/ subdirs were missing in the old fixture mirror but present in
canonical; copy them alongside their manifests so consumers that
resolve ``target.splits`` (currently latent in VisCy, used by
dynacell-paper) work correctly.

Drift between this bundled copy and dynacell-paper canonical is guarded
by ``test_manifest_sync.py`` — parametrized over every shipped dataset,
parses both YAML files and asserts canonical is a subset of VisCy
(VisCy may carry additive fields like ``gt_cache_dir``). Skipped unless
``DYNACELL_PAPER_PATH`` is set, so CI behaves predictably while local
dev catches drift early.

This is the cheapest fix for the viscy <-> dynacell-paper logical
cycle: single PR, no new package. Heavier options (extracting a
``dynacell-manifests`` leaf package + ``DYNACELL_DATA_ROOT`` for path
portability) deferred per architecture discussion.

 infected sbatch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds --constraint='h200|h100_80|a100_80' so the 4xGPU prod run is
guaranteed at least 80 GB per device. The 3-DM CombinedDataModule in
MAX_SIZE_CYCLE produces 16x4x3 = 192 crops/step/GPU — measured
against a live dynacell FCMAE H200 reference (~45 GB at single-DM
128 crops/step), the projected per-GPU footprint is ~67 GB. That
fits comfortably on H200, ~84% of an 80 GB H100/A100, and would OOM
on a 40 GB A100 or 48 GB A40/A6000.

Subject: [PATCH 220/311] docs(dynacell): note manifest registry drift policy
 in README

Direct follow-up to 2395e1d (bundled manifest registry). Explains the
two-source-of-truth split: VisCy ships the manifest content
(``src/dynacell/_manifests/``, auto-discovered via the
``dynacell.manifest_roots`` entry point), and ``dynacell-paper`` remains
the source of truth for manifest authoring. When a new plate lands in
``dynacell-paper``, mirror it back into VisCy; ``test_manifest_sync.py``
catches drift when ``DYNACELL_PAPER_PATH`` is set.

+## Manifest registry (drift policy)
+
+Benchmark leaves resolve `benchmark.dataset_ref` lookups against a bundled
+manifest registry shipped with the dynacell wheel at
+`applications/dynacell/src/dynacell/_manifests/`. The resolver auto-discovers
+this via the `dynacell.manifest_roots` entry point, so `uv run dynacell
+predict -c <leaf>` works out of the box without `DYNACELL_MANIFEST_ROOTS`.
+Override the env var to point at an alternate registry for testing.
+
+VisCy is the source of truth for manifest **content**; `dynacell-paper`
+remains the source of truth for manifest **authoring**. When a new plate
+is preprocessed in `dynacell-paper`, mirror the new manifest (and its
+`splits/` siblings) into `applications/dynacell/src/dynacell/_manifests/`.
+The `tests/test_manifest_sync.py` suite catches drift when run with
+`DYNACELL_PAPER_PATH=/path/to/dynacell-paper` set.

Subject: [PATCH 221/311] feat(dynacell): submit_benchmark_job.py supports
 optional --dependency, --parsable (#416)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(dynacell): submit_benchmark_job.py supports optional --dependency, --parsable

Adds two opt-in flags to enable orchestration that needs to chain
sbatch jobs by ID:

- --dependency afterok:<job_id> appends --dependency=<value> to the
  sbatch invocation. Default off.
- --parsable invokes sbatch with --parsable (which makes sbatch print
  just the numeric job ID instead of "Submitted batch job <id>"),
  captures that ID, and forwards it to stdout. Default off.

Both flags default off. Manual submit_benchmark_job.py <leaf>
invocations build the same ["sbatch", str(sbatch_path)] command as
before, with stdout untouched — every existing workflow (smoke jobs,
ad-hoc submissions, model-iteration scripts) sees no behavior change.

Why: dynacell-paper's upcoming benchmarks orchestrator (Phase 5F)
needs to capture train job IDs so it can submit predict with
--dependency=afterok:<train_id>, chaining the train → predict pair
via SLURM. Without these flags, the orchestrator would have to parse
"Submitted batch job <id>" prose from a non-captured stdout — brittle.

Tests: 5 new monkeypatched cases covering the default shape (backward
compat) plus the three new flag combinations. No live sbatch.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(dynacell): keep stderr attached + clarify --parsable wording

Two Copilot findings on PR #416:

1. ``--parsable`` previously used ``capture_output=True``, which
   captures both stdout and stderr — sbatch warnings and diagnostics
   were silently swallowed on success. Switch to
   ``stdout=subprocess.PIPE`` so stderr stays attached to the parent
   and only the parsable line is captured.

2. ``--parsable`` help text claimed to "forward the parsed job ID"
   but the implementation forwards sbatch's parsable stdout verbatim,
   which can be ``job_id;cluster`` on multi-cluster setups. Update
   wording to describe the forwarding accurately.

Test asserts the new kwarg shape (``stdout=PIPE``, no ``stderr``,
no ``capture_output``).

 predict_set fragments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds bundled manifests for a549-mantis plates 2024_10_31, 2024_11_05,
2025_07_24, 2025_08_26 — the per-plate predict_set fragments below need
their dataset_ref to resolve at compose time, so the manifests are
mirrored into dynacell._manifests parity with canonical dynacell-paper
configs (test_manifest_sync.py enforces).

Predict_set fragments author one-line dataset_ref redirects per plate so
existing per-plate predict leaves can switch plates without touching the
data block.

Subject: [PATCH 223/311] feat(dynacell): per-plate A549 predict leaves for ER
 + MITO across 5 models

Today's predict__a549_mantis.yml only covered ONE plate (ER: 2024_11_07,
MITO: 2024_11_21). The A549 SEC61B test budget spans 4 plates and TOMM20
spans 4 plates, so a single-plate predict leaf cannot cover the full
test set. Plan-time gap: per-plate iteration was deferred under the
assumption a single demo plate was enough, which conflicts with the
data-design test-set spec.

For each (organelle, model) in {er, mito} x {celldiff, fcmae_vscyto3d_*,
fnet3d_paper, unetvit3d}, replace predict__a549_mantis.yml with one
plate-scoped leaf per applicable test plate (ER: 2024_10_31, 2024_11_07,
2025_07_24, 2025_08_26; MITO: 2024_11_05, 2024_11_21, 2025_07_24,
2025_08_26). Each leaf composes its plate's predict_set and writes to
a plate-suffixed output zarr so concurrent runs never clobber.

40 leaves total (4 models x 4 plates x 2 organelles + 5th model on each
side: FNet ER already had 4 from the SEC61B-only refactor, MITO adds 4).

Subject: [PATCH 224/311] =?UTF-8?q?feat(dynacell):=20submit=5Fbenchmark=5F?=
 =?UTF-8?q?batch.py=20=E2=80=94=20chain=20N=20predict=20leaves=20into=20on?=

Path-1 batching for predict-only workflows: composes each leaf via
load_composed_config, writes one resolved config per leaf with stable
plate-scoped names under {run_root}/resolved/, and renders ONE sbatch
script that loops `python -m dynacell predict --config <resolved>` over
all of them. Amortizes queue submission and GPU allocation; total
compute is unchanged from N per-leaf jobs.

Validates that all leaves agree on launcher.mode (predict only),
launcher.run_root, and the sbatch hardware profile (nodes/gpus/mem/etc).
trainer.devices must equal sbatch.ntasks_per_node — same Lightning
SLURMEnvironment invariant as submit_benchmark_job.py.

predict_all_a549.sh wraps the new tool: globs every
predict__a549_mantis_*.yml under <organelle>/<model>/ipsc_confocal/ and
hands them to submit_benchmark_batch.py with a composite job_name. Used
to re-run FNet ER + MITO predictions across all 4 plates (jobs
31558746 + 31558818).

+r"""Submit a sequence of dynacell predict leaves as ONE sbatch job.
+
+Composes each leaf via :func:`viscy_utils.compose.load_composed_config`,
+strips reserved keys, writes one resolved config per leaf to
+``{run_root}/resolved/`` with stable plate-scoped filenames, then renders
+ONE sbatch script (from ``sbatch_template_batch.sbatch``) that invokes
+``python -m dynacell predict --config <resolved>`` for each leaf in
+order. Useful for chaining per-plate predict leaves into a single sbatch
+to amortize queue submission and GPU allocation.
+
+Constraints (predict-only by design):
+  * All leaves must share ``launcher.mode == 'predict'`` and the same
+    ``launcher.run_root``. Mixing modes or run_roots raises.
+  * Leaves' SBATCH directives are merged from the FIRST leaf's
+    ``launcher.sbatch`` block; subsequent leaves' sbatch blocks must
+    match (same hardware profile). The composite job_name is taken
+    from ``--job-name`` if provided, else derived from the first
+    leaf with a ``_batch`` suffix.
+  * Wall time defaults to ``--time`` if provided; else uses the first
+    leaf's ``sbatch.time`` multiplied by len(leaves) (rounded up to
+    the next hour).

Subject: [PATCH 225/311] feat(dynacell): compute FID/KID at dataset level
 across all cells

Pool all cell features from every FOV and timepoint before computing
FID and KID, replacing the previous per-timepoint image-to-image
comparison. Cosine similarity remains per-timepoint. The single
dataset-level FID/KID value is broadcast to every row in the output
CSV so the column structure is preserved.

Subject: [PATCH 226/311] feat(dynacell): add per-model eval scripts in model
 subfolders

One script per CELL-Diff variant (denoise, sliding_window, iterative)
in celldiff/, one for UNetViT3D in unetvit3d/, and one for FNet3D in
fnet3d/. Each script covers all four organelles (ER, membrane,
mitochondria, nucleus) following the run_eval_fnet.sh format.

Subject: [PATCH 227/311] fix(dynacell): use uv run consistently and fix pred
 path in eval scripts

Add missing force_recompute.all=true and uv run prefix to run_eval_fnet.sh.
Fix nucleus UNetViT3D pred path (nucleus_ -> nucl_) in run_eval_nucl.sh.

Subject: [PATCH 228/311] refactor(dynacell): consolidate eval scripts into
 model subfolders

Remove top-level per-organelle and per-model scripts; canonical scripts
now live in celldiff/, unetvit3d/, and fnet3d/. Fix source path to
use relative .envrc in all subfolder scripts.

Subject: [PATCH 229/311] chore(manifests): point a549-mantis stores at .ozx
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Flip stores.{train,test}: paths from .zarr to .ozx across all 7
bundled a549-mantis plate manifests. Mirrors the same change in
dynacell-paper (commit 6514090); test_manifest_sync.py asserts
semantic equality with canonical.

OZX is the new test corpus container — RFC-9 packed, 512x512
center-crop. 9 test stores exist on disk (all hosting plates).
The 2026_03_26 train side has no OZX yet; both CAAX/H2B train:
paths are placeholders that will land when train assembly runs.

Subject: [PATCH 230/311] feat(dynacell): add --override + --overwrite to
 submit_benchmark_batch.py

The batch submitter previously had no way to inject per-leaf flags, so
re-running a chained predict over plates whose output stores already
contained the prediction channel required either rm-ing the stores or
hand-editing every leaf.

Add two CLI flags, both off by default:

- --override KEY.PATH=VALUE (repeatable): same dotlist semantics as
  submit_benchmark_job.py, applied to each composed leaf via
  viscy_utils.compose.deep_merge.
- --overwrite: dedicated alias that walks trainer.callbacks per leaf
  and sets init_args.overwrite=True on every entry whose class_path
  ends with HCSPredictionWriter. Sidesteps deep_merge's dict-key-only
  limitation (callbacks[0]-style overrides silently no-op).

predict_all_a549.sh forwards extra args via "$@" already; doc comment
updated to mention --overwrite as the canonical way to re-run a plate
with existing predictions.

Subject: [PATCH 231/311] feat(dynacell): add --overwrite alias to
 submit_benchmark_job.py for parity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirror the alias just added to submit_benchmark_batch.py: a dedicated
--overwrite flag that walks trainer.callbacks and sets
init_args.overwrite=True on every HCSPredictionWriter entry, off by
default.

The existing --override "trainer.callbacks[0].init_args.overwrite=true"
recommendation was a latent no-op — viscy_utils.compose.deep_merge is
dict-key-only and the [0] segment becomes a literal key, leaving the
real callback untouched. The alias matches by class_path suffix and
works against the actual list, so single-leaf submitters now have the
same path as the batch submitter.

Also clarifies the --override help text on the same caveat so callers
don't reach for the broken syntax.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirror of predict_all_a549.sh but for local execution rather than sbatch
submission. Stages resolved YAMLs through submit_benchmark_job.py
--dry-run (so the resolved/ tree gets the same provenanced timestamped
filenames a sbatch run would), then invokes `dynacell predict` directly
on each, optionally N at a time on the same GPU.

Args:
- <organelle> <model>       — discover predict__a549_mantis_*.yml leaves
                              under configs/.../<organelle>/<model>/ipsc_confocal/
- --overwrite                — forwarded to submit_benchmark_job.py;
                              required to re-run a leaf whose output
                              store already contains the prediction channel
- --parallel N (default 1)   — run N predicts concurrently on one GPU,
                              waiting between batches. Tune to fit VRAM
                              (~2 fnet predicts fit on an A40)

Logs land at $run_root/slurm/local_<TS>_<organelle>_<model>_<plate>.log.
Uses `unbuffer` when available so TQDM progress bar streams to the log;
falls back to plain `uv run` with a warning otherwise. SIGINT trap kills
backgrounded predicts on early exit. Fail-fast: a failing plate aborts.

Subject: [PATCH 233/311] fix(dynacell): predict_local_a549.sh dying after
 first plate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Under set -e, ((i++)) returns exit status 1 when i is 0 (the post-
increment value 0 is treated as a failure by bash's arithmetic-eval
exit-status rule). On the first loop iteration i goes 0 → 1, the
((i++)) expression evaluates to 0 → script exits → the EXIT trap fires
kill 0 → both the script and the already-launched predict child are
SIGTERM'd. Symptom: stage phase completes, run phase prints the first
[start] line, then job control reports "terminated" with no logs and
no zarr output.

Replace with a pure-assignment increment (i=$((i + 1))) which has no
exit-status side effect. Loop now actually iterates. Reproducer:

  bash -c 'set -e; i=0; ((i++)); echo survived' || echo killed
  # → killed

Subject: [PATCH 234/311] fix(dynacell): predict_local_a549.sh - probe unbuffer
 + catch child failures

Two issues exposed by the mito fnet3d run that completed in 30s with no
output:

1. unbuffer detection was PATH-only. On nodes that ship the wrapper
   without the Tcl Expect package, unbuffer crashes immediately
   ("can't find package Expect"), all backgrounded predicts die in <1s.
   Add a runtime probe (`unbuffer true`) so a broken install falls
   through to the plain-uv runner.

2. set -e does NOT propagate background-job failures through `wait`
   (bash treats async failures as already-handled), so a batch where
   every child died still printed "[done] all leaves complete". Track
   each backgrounded predict's PID + plate + log path; after each
   batch, wait per-PID and record non-zero exits in FAILED_PLATES;
   on script end, print a [fail] summary and exit 1 if any plate
   failed.

Subject: [PATCH 235/311] feat(dynacell): tomm20 fcmae scratch predict leaves
 pinned to best ckpt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add the 4 mito/fcmae_vscyto3d_scratch/ipsc_confocal predict leaves
(3 a549_mantis + 1 ipsc_confocal) pinned to epoch=69-step=21840.ckpt
(val 0.5527) from training run J31475715. Run was cancelled at epoch
164 — val loss plateaued at epoch ~51 and never recovered, so later
checkpoints are not better than the locked-in best.

Subject: [PATCH 236/311] feat(dynacell): matrix-fill iPSC predict leaves for
 remaining 7 FCMAE leaves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add ipsc_confocal predict configs across the FCMAE_VSCyto3D family
(scratch + pretrained × {nucleus, membrane, er} + mito pretrained).
All 7 use the TODO_FILL_BEFORE_SUBMIT sentinel for ckpt_path; header
comments cite the corresponding training job ID and on-disk dir to
search once each run locks in a best-val checkpoint.

Sibling families (celldiff, fnet3d_paper, unetvit3d) all had iPSC
predict leaves; FCMAE didn't. Closing the matrix gap so a single
submit-all sweep covers every model × organelle.

From b0c0f24b83aff3fe3e232f07b140ba845ef04aaf Mon Sep 17 00:00:00 2001
From: Alexandr Kalinin <alxndrkalinin@users.noreply.github.com>

Subject: [PATCH 237/311] chore(dynacell): drop legacy per-date a549_mantis
 registry + leaves

Remove the old per-date a549_mantis configuration tree across three
layers:

  - 7 manifest registries (2024_10_31, 11_05, 11_07, 11_21, 2025_07_24,
    2025_08_26, 2026_03_26) under src/dynacell/_manifests/, including
    their per-organelle train_test split files.
  - 7 shared predict_sets/a549_mantis_<date>.yml shards.
  - 56 per-date predict__a549_mantis_<date>.yml + eval__a549_mantis.yaml
    leaves under <organelle>/{celldiff,unetvit3d,fnet3d_paper,fcmae_*}/
    ipsc_confocal/ and the matching _internal/leaf/ templated stubs.

Replaced by per-condition leaves (mock/denv/zikv) anchored to a single
2026_03_26 plate, landing in subsequent commits. Leaving these files
in the tree would let stale path references resolve and silently run
against deprecated data.

Subject: [PATCH 238/311] feat(dynacell): per-condition a549_mantis registry +
 predict/eval matrix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the deleted per-date a549_mantis tree with a per-condition
layout keyed on (organelle_marker, viral_condition):

  - 12 manifest registries: a549-mantis-{caax,h2b,sec61b,tomm20}-{mock,
    denv,zikv}/ with manifest.yaml + splits/*_train_test.yaml.
  - 12 shared predict_sets: _internal/shared/model/predict_sets/
    a549_mantis_<marker>_<condition>.yml, each resolving its data_path
    via dataset_ref to the matching pooled test store.
  - 60 _internal/leaf templated stubs: 4 organelles × 5 model families ×
    3 conditions for eval__a549_mantis_<cond>.yaml (concrete predict
    files duplicate the leaf body so are not symlinked).
  - 117 concrete user-facing leaves: predict__a549_mantis_<cond>.yml +
    eval__a549_mantis_<cond>.yaml under <organelle>/<model_family>/
    ipsc_confocal/, mock/denv/zikv per leaf. The mito/fcmae_vscyto3d_
    scratch trio is already in ac6c1592 and skipped here.

Each leaf composes against the same shared predict_set + the existing
target/model_overlay/launcher_profile bases — no new shared bases.

Subject: [PATCH 239/311] feat(dynacell): a549 evaluation runner scripts for
 fnet3d + unetvit3d
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add bash launchers that drive the existing dynacell evaluate CLI over
the cropped 512x512 OZX test corpus for A549. Pixel + segmentation
tracks only — cell_segmentation_path is not authored for A549 yet, so
compute_feature_metrics=false. force_recompute.all=true is mandatory
because the OZX rebuild changed shape and any cached gt_masks /
final_metrics from prior runs are stale.

 =?UTF-8?q?c.sh=20=E2=80=94=20local=20ipsc=5Fconfocal=20predict=20runner?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Companion to predict_local_a549.sh for the ipsc_confocal predict_set.
Stages <organelle>/<model>/ipsc_confocal/predict__ipsc_confocal.yml via
submit_benchmark_job.py --dry-run, then runs `uv run dynacell predict`
directly on the current host's GPU — no sbatch.

Each ipsc leaf dir holds a single predict__ipsc_confocal.yml (vs. the
3 per-plate a549 leaves), so the script drops --parallel and the glob
loop, but keeps the staging + unbuffer probe + log-naming idioms from
the a549 script.

Subject: [PATCH 242/311] feat(dynacell): ER joint train uses pooled a549
 SEC61B_all store

Swap the a549-side data_path from the per-date single-plate store
mantis_v1/2024_11_07_A549_SEC61_DENV/train/SEC61B.zarr to the pooled
all-conditions store mantis_v1/train/SEC61B_all.zarr in 4 ER joint
train YAMLs (celldiff train + train_smoke + train_smoke_4gpu, plus
fnet3d_paper train_smoke). Pooled store mirrors the per-condition
manifest registry layout introduced in 503774b5.

Subject: [PATCH 243/311] chore(dynacell): drop legacy predict__a549_mantis
 leaves for membrane + nucleus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Finishes the per-date → per-condition predict-leaf sweep started in
b0c0f24b (er + mito) and 503774b5 (per-condition manifest registry +
predict/eval matrix). The single-file legacy a549 predict leaves
under <organelle>/<model>/ipsc_confocal/predict__a549_mantis.yml are
replaced by per-plate predict__a549_mantis_{mock,denv,zikv}.yml which
already exist for all 5 model variants × 2 organelles.

From d985a76b19c399e0e833f2ca24d71b9f5876865e Mon Sep 17 00:00:00 2001
From: Alexandr Kalinin <alxndrkalinin@users.noreply.github.com>
Date: Wed, 29 Apr 2026 23:49:21 -0700
Subject: [PATCH 244/311] feat(dynacell): nucleus fcmae pretrained predict
 leaves pinned to best ckpt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pin the 4 nucleus/fcmae_vscyto3d_pretrained/ipsc_confocal predict
leaves (ipsc_confocal + 3 a549 plates) to the best-val checkpoint
from training run J31475094 (val 0.3921, epoch 89). Run cancelled at
epoch 172 — val plateaued at epoch 89 and never recovered (~83
epochs without improvement). Replaces /TODO_FILL_BEFORE_SUBMIT
sentinels and reflows headers to record the cancellation rationale.

Subject: [PATCH 245/311] feat(dynacell): sec61b fcmae scratch predict leaves
 pinned to best ckpt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pin the 4 er/fcmae_vscyto3d_scratch/ipsc_confocal predict leaves
(ipsc_confocal + 3 a549 plates) to the best-val checkpoint from
training run J31483778 (val 0.4119, epoch 122). Run cancelled at
epoch 164 — val plateaued at epoch 122 and never recovered (~42
epochs without improvement, drifting up in last 5 epochs). Replaces
/TODO_FILL_BEFORE_SUBMIT sentinels and reflows headers to record the
cancellation rationale.

Subject: [PATCH 247/311] chore(security): warn against upgrading past
 lightning 2.6.1
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PyPI lightning 2.6.2 / 2.6.3 ship a credential-harvesting payload that
runs on import (socket.dev advisory, 2026-04-30: exfiltrates AWS / Azure
/ GCP creds + GitHub / npm tokens, plants .claude/router_runtime.js).
The current uv.lock pins 2.6.1 (the last clean release), so
`uv sync --frozen` / CI flows are safe — but `uv lock --upgrade` would
silently jump to 2.6.3.

Adding a hard constraint via [tool.uv] {constraint,override}-dependencies
breaks resolution: lightning 2.6.1's transitive chain (torch>=2.10 has
no py3.14+win32/linux wheel) doesn't fully resolve under uv's universal
locking once 2.6.2+ is excluded. Inline warning instead, until Lightning
AI publishes a clean post-2.6.3 release we can pin upward to.

Subject: [PATCH 248/311] feat(dynacell): joint ipsc_confocal+a549_mantis train
 leaves for 7 cells
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds production 4-GPU DDP joint train.yml for the 7 missing
organelle×model cells (er/unetvit3d, mito/{celldiff,unetvit3d},
nucleus/{celldiff,unetvit3d}, membrane/{celldiff,unetvit3d});
er/celldiff already had the reference leaf.

Mirrors the existing er/celldiff/joint_*/train.yml pattern:
BatchedConcatDataModule wrapping two HCSDataModule children (iPSC
single-marker store + A549 pooled-conditions store), inherits the
A100-excluded constraint from hardware_4gpu, per-model ckpt
conventions preserved (celldiff: save_top_k=-1; unetvit3d:
monitor=loss/validate save_top_k=4). Channel + data_path mapping
follows each target's manifest (er/mito → Structure on
{SEC61B,TOMM20}, nucleus → Nuclei on cell.zarr+H2B_all.zarr,
membrane → Membrane on cell.zarr+CAAX_all.zarr).

Unblocks Stage 7 of A549_EXPANSION_ROADMAP.md once the
ConcatDataModule.setup trainer-propagation fix lands.

From 4c53eaf89f73048dfc20ee7f2e41d852f3d781be Mon Sep 17 00:00:00 2001

Subject: [PATCH 249/311] fix(security): pin lightning to direct CDN URL after
 PyPI quarantine
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PyPI quarantined the entire `lightning` package on 2026-04-30 in
response to the 2.6.2 / 2.6.3 supply-chain compromise (socket.dev
advisory: malicious payload exfiltrates AWS / Azure / GCP creds +
GitHub / npm tokens on import). The package index now serves zero
versions, so `uv lock` cannot resolve `lightning>=2.3` against PyPI
at all — and the inline-comment guard from 0d72bbfd is unenforceable.

Switch to a direct wheel URL pin via [tool.uv.sources] — the
files.pythonhosted.org CDN still serves the clean 2.6.1 wheel
independently of the index quarantine. The URL embeds the SHA, so
the wheel can't be silently swapped, and `uv lock --upgrade` has no
effect because the source is fixed.

Drop this pin once PyPI un-quarantines lightning and Lightning AI
publishes a clean post-2.6.3 release.

Subject: [PATCH 250/311] fix(viscy-utils): HCSPredictionWriter idempotent on
 multi-timepoint inputs

The existence check ``img_name in self.plate.zgroup`` does not
reliably detect positions created earlier in the same writer
(zarr3 nested-path lookups combined with the leading slash in
img_name miss in-progress entries). On any multi-timepoint input
the second batch for a given FOV re-entered the create branch and
crashed with ``FileExistsError`` from ``position.create_zeros``.
Surfaced on every prediction over A549 mantis test pools (T=10).
The iPSC test corpora have T=1 so the bug stayed latent there.

Replace the membership check with try/except on plate.__getitem__
which iohub already accepts for both leading-slash and
stripped-path lookups and raises KeyError on miss.

Subject: [PATCH 251/311] feat(dynacell): joint train leaves for
 fcmae/fnet3d/unext2 (13 cells)

Adds joint_ipsc_confocal_a549_mantis/train.yml across the remaining
model x organelle cells the prior celldiff/unetvit3d joint commit
(eef14596) did not cover:

  - er/{fcmae_pretrained, fcmae_scratch, fnet3d_paper, unext2}
  - mito/{fcmae_pretrained, fcmae_scratch, fnet3d_paper}
  - membrane/{fcmae_pretrained, fcmae_scratch, fnet3d_paper}
  - nucleus/{fcmae_pretrained, fcmae_scratch, fnet3d_paper}

All 13 follow the established joint pattern: compose only
model_overlays/<model>_fit.yml + mode_fit + hardware_4gpu +
runtime_shared, then author the BatchedConcatDataModule data block
inline with two HCSDataModule children sharing init_args via the
&hcs_init_args YAML anchor. Per-organelle constants (target_channel,
ipsc/a549 zarr paths) match the existing celldiff/unetvit3d joint
leaves.

Per-model deltas vs the celldiff/unetvit3d joint shape:
- fcmae_*: data hparams from data_overlays/fcmae_vscyto3d_fit.yml
  (z=20, bs=32, yx=384, RandWeightedCropd[20,600,600,n=4], no
  safe_crop_size, post-affine center crop to 15x384x384). Pretrained
  variant adds model.init_args.encoder_only/ckpt_path. No leaf-level
  ddp override -- ddp_4gpu + ddp_find_unused_parameters_true come from
  the model overlay.
- fnet3d_paper: data hparams from data_overlays/fnet3d_paper_fit.yml
  (z=32, bs=48, yx=64, RandWeightedCropd[32,64,64,n=8], target
  normalized with mean/std not median/iqr, GPU flip-only augs, CPU
  CenterSpatialCropd val_augmentations). Adds strategy=ddp + devices=4
  override since the overlay pulls in topology/single_gpu.yml.
  Topology deviates from the paper's single-GPU run for joint-config
  consistency; override leaf-level strategy/devices for paper-faithful
  joints.
- unext2: data hparams from data_overlays/unext2_fit.yml (z=20, bs=32,
  yx=384, RandWeightedCropd[20,600,600,n=4]). Only er has a single-set
  unext2 leaf today; mito/membrane/nucleus joint unext2 not generated.

Run roots track each single-set's existing convention:
  dynacell/joint_ipsc_confocal_a549_mantis/<short>/<model_subdir>
where <model_subdir> matches each single-set's tail (e.g. er + mito
fcmae_pretrained ship the _ws8500 suffix, memb + nucl do not).

Each leaf was verified with `submit_benchmark_job.py
--print-resolved-config`: all 13 compose to devices=4 with the right
strategy and bs.

Subject: [PATCH 252/311] fix(dynacell): fnet3d_paper joint train leaves are
 single-GPU like iPSC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 4 fnet3d_paper joint train leaves (er/mito/nucleus/membrane) were
inheriting hardware_4gpu and overriding strategy/devices to ddp/4 —
diverging from the paper baseline which is single-GPU. Joint runs need
to mirror their iPSC counterpart's topology so iPSC-only and joint
runs are apples-to-apples; otherwise the only signal the experiment
isolates is "joint vs iPSC", but the device count is also changing.

Switch to hardware_gpu_any_long (1 GPU, no constraint, 20-day wall —
same as fnet3d_paper/ipsc_confocal/train.yml) and drop the leaf-level
strategy: ddp / devices: 4 overrides so the model_overlay's
single_gpu topology survives. Update the topology comment to reflect
the alignment with the iPSC fnet leaf.

Subject: [PATCH 253/311] fix(dynacell): align joint train channel typing with
 iPSC (str not list)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

iPSC train leaves resolve `data.init_args.{source,target}_channel` as
scalar strings via the manifest dataset_ref. The joint leaves were
hard-coding them as single-element YAML lists, so composed configs
diverged on channel typing for every leaf. HCSDataModule normalizes
both forms via `_ensure_channel_list`, so behavior is identical at
runtime — but to keep iPSC-only and joint runs apples-to-apples in
the resolved YAML, switch joint leaves to scalar form.

Affects all 21 joint train.yml leaves (4 organelles × every model
present, plus er/celldiff existing reference).

Subject: [PATCH 254/311] fix(dynacell): celldiff + unetvit3d joint train
 leaves are single-H200 like iPSC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 8 celldiff and unetvit3d joint train leaves were using
hardware_4gpu and overriding strategy/devices to ddp/4 — diverging
from their iPSC counterparts which are single-H200 (hardware_h200_single).
For a clean iPSC-vs-iPSC+A549 comparison, the only thing that should
differ between the runs is the data: changing GPU count too confounds
the experiment.

Switch to hardware_h200_single (1 GPU, h200 constraint, 4-day wall —
same as <model>/ipsc_confocal/train.yml) and drop the leaf-level
strategy: ddp / devices: 4 overrides so the model_overlay's
single_gpu topology survives. Update the topology comment to reflect
the alignment with the iPSC leaf.

Note: the BatchedConcatDataModule sampler block still works on a
single GPU — torch.distributed.is_initialized() returns False, the
sharded sampler isn't attached, and the joint dataset uses a normal
DataLoader shuffler.

 membrane (matches iPSC)

cell.zarr-backed preload pushes MaxVMSize past hardware_gpu_any_long's
256G default. The single-set fnet leaves for nucleus/membrane already
override `launcher.sbatch.mem: "512G"` for this reason; mirror it on
the joint side so the only difference between iPSC-only and joint
runs is the data block.

Subject: [PATCH 256/311] fix(dynacell): bump joint train mem to 512G (preloads
 two stores)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Joint training uses BatchedConcatDataModule with mmap_preload on two
HCSDataModule children (iPSC + A549 pool), so /dev/shm holds both
stores plus per-worker peak mem. The 256G default from
hardware_h200_single / hardware_gpu_any_long was sized for single-set
runs (iPSC alone, ~85-100G data) and OOMs on joint runs once A549
preload starts on top of iPSC's already-preloaded /dev/shm
(observed on SLURM 31811526 — fnet3d_paper er joint OOM'd 3:31 in,
right after iPSC SEC61B preload completed and A549 SEC61B_all preload
began).

Set leaf-level mem=512G on the 10 joint leaves whose composed mem
was 256G (er/mito {celldiff, unetvit3d, fnet3d_paper} +
nucleus/membrane {celldiff, unetvit3d}). Other joint leaves are
unchanged: nucleus/membrane fnet3d_paper already at 512G;
fcmae+unext2 already at 1024G via hardware_4gpu.

Subject: [PATCH 257/311] =?UTF-8?q?feat(dynacell):=20a549-only=20train=20l?=
 =?UTF-8?q?eaves=20for=20all=2021=20organelle=C3=97model=20cells?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a549-only training configs as a third train_set alongside
ipsc_confocal and joint_ipsc_confocal_a549_mantis. Composed configs
match the iPSC counterpart exactly except for the data block, naming,
and run_root/log paths — verified across all 21 cells with the same
audit harness used for the joint leaves.

New train_set fragment:
  _internal/shared/model/train_sets/a549_mantis.yml — provides
  benchmark.train_set + dataset_group + bare HCS hparams (split_ratio,
  mmap_preload, scratch_dir, persistent_workers, source_channel).
  Does NOT set dataset_ref because no canonical manifest exists for
  the pooled mantis_v1/train/<TARGET>_all.zarr stores; the resolver
  is a strict no-op when dataset_ref.dataset is missing, so leaves
  authoring data.init_args.{target_channel, data_path} inline alongside
  the targets/<X>.yml fragment compose cleanly.

Per-cell leaves at <organelle>/<model>/a549_mantis/train.yml:
  Generated by mirroring each ipsc_confocal/train.yml — same model
  overlay, data overlay, target fragment, hardware profile, callbacks,
  and per-model hparams. The only delta is data_path (pointing at the
  pooled A549 store) and the train_set/path/name suffixes
  (a549_mantis vs ipsc_confocal). Mem allocations match iPSC: the
  pooled A549 stores (47-75G) are smaller than iPSC SEC61B/cell.zarr,
  so any iPSC-side mem override (e.g., nucleus/membrane fnet at 512G)
  is preserved verbatim and remains generous for a549-only.

Subject: [PATCH 258/311] feat(dynacell): switch celldiff a549_mantis predict
 configs to iterative, z_window=48

All organelles (er, membrane, mito, nucleus) updated to iterative predict_method
with z_window_size=48; output store paths updated to reflect iterative suffix.
Drop legacy predict__a549_mantis.yml leaves (membrane + nucleus).

Subject: [PATCH 260/311] fix(dynacell): bump joint fnet3d nucl/memb mem
 512G->1024G (OOM)

J31812394 (FNet3DPaper_JOINT_NUCL) was OOM-killed during mmap_preload
(MaxRSS 432.9 GB, ReqMem 512G). Two datasets stack in /dev/shm: the
500-FOV iPSC cell.zarr already burns ~430 GB on its own, and the
A549 H2B_all.zarr (or CAAX_all.zarr for membrane) staging on top
pushes the cumulative working set past the 512G cgroup cap.

Single-set fnet3d_paper at 512G is fine because only cell.zarr is
preloaded; the joint variant needs 1024G headroom for both stages.
ER + MITO joint fnet3d configs are unaffected (SEC61B/TOMM20 zarrs
are smaller) and stay at 512G.

Subject: [PATCH 261/311] fix(dynacell): bump a549 nucl fnet3d mem 512G->1024G
 (OOM)

J31817942 (FNet3DPaper_A549_NUCL) OOM-killed during mmap_preload of
H2B_all.zarr alone (no joint with cell.zarr). MaxRSS hit 498 GB on
the 512G cap. The dense theoretical stage size is only ~71 GB
(30 FOVs * T=10 * 2 ch * Z=48 * Y=640 * X=960 * 4 bytes), so the
T>1 multi-timepoint pooled A549 store amplifies ~7x in cgroup
accounting (tmpfs file + 16-thread transient buffers + zarr
decompression overhead). Bump to 1024G with margin to clear the cap.

Comment also updated: prior copy-pasted "cell.zarr-backed" rationale
was wrong for the a549-only leaf (no cell.zarr in that train_set).

Subject: [PATCH 262/311] chore(cytoland): repoint A549 infected configs from
 Lustre to VAST

The three A549 infection zarrs (D1 Hummingbird 2026-01-29, D2 Hummingbird
2026-03-10, D3 Mantis 2026-03-26) are being copied from Lustre
(/hpc/projects/intracellular_dashboard/...) to VAST under
/hpc/projects/virtual_staining/training/a549/2026_05_infected_cell/ so the
finetune isn't bottlenecked by Lustre read latency under mmap_preload.

Updates 7 data_path references across:
- recipes/data/hcs_a549_infected_d{1,2,3}*.yml (3 fragments)
- vscyto3d/finetune_a549_infected.yml (3 inline sub-DMs)
- vscyto3d/preprocess_a549_infected_d3.sh (--data_path arg)

Configs will only resolve once the rclone copy lands on VAST. The copy
itself is driven by copy_a549_infected_to_vast.sh in the same dir.

Subject: [PATCH 263/311] fix(viscy-data): mmap_preload reads via BasicIndexer
 (~6x less RAM)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

prepare_data was using arr.oindex[:, ch_idx, :] to select channels.
For sharded zarr v3 stores, that path routes through CoordinateIndexer,
which np.broadcast_arrays the per-axis index arrays up to the full
output shape (zarr/core/indexing.py:1206-1216) — i.e., 5 dense int64
arrays sized prod(out_shape) per call. Memray attributed 75.9% of
total allocations to that single genexpr.

Empirically the inflation peaks at ~7x dense for slab selections on
sharded T>1 stores. Concretely on the dynacell pipeline:
  - 30-FOV H2B_all (70.8 GB dense) → OOM at 990 GB cgroup mem (1T cap)
  - 5-FOV probe → 81 GB peak heap

Replace with per-channel basic indexing + numpy concat. BasicIndexer
allocates O(out_shape) only, same I/O, same chunk-granular reads,
identical bytes. Probe v4 confirms peak drops 81 GB → 16 GB on the
same 5-FOV workload (5.2x reduction); 30-FOV preload now sits at
~75 GB (the legitimate dirty-mmap-pages residual on tmpfs).

Apply the same pattern to the optional fg_mask staging path so the
mask buffer doesn't blow up the same way.

Add test_mmap_preload_matches_oindex: parameterized over zarr v2 and
v3 (sharded) via the existing preprocessed_hcs_dataset fixture,
asserts the staged buffer is byte-equal to arr.oindex[:, ch_idx, :]
per FOV. All 57 tests in test_hcs.py pass.

Refs upstream zarr-python issues #3164, #3641 (sharded indexing
memory) — does not depend on an upstream fix.

Subject: [PATCH 264/311] revert(dynacell): drop fnet3d mem overrides after
 mmap_preload fix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 1024G mem overrides on a549/nucl, joint/nucl, and joint/memb
fnet3d_paper leaves were workarounds for the prepare_data oindex heap
blowup, addressed in the prior commit. With BasicIndexer routing,
peak preload heap is now ~75 GB for H2B_all alone and ~185 GB for the
joint cell.zarr + H2B_all/CAAX_all stages — all comfortably under the
hardware_gpu_any_long default of 256G.

Drop the leaf-level sbatch.mem overrides and let the configs inherit
the profile default. Reduces wasted node memory reservation across
the four affected runs.

Subject: [PATCH 266/311] fix(dynacell): set
 PYTORCH_ALLOC_CONF=expandable_segments:True

Adds the env var to runtime_shared.yml so all dynacell jobs run with
PyTorch's expandable VA segments enabled. Avoids fragmentation-driven
CUDA OOMs in workloads where activation tensors change shape across a
forward+backward pass (e.g. U-Net skip-concat doubling channels mid-
decoder).

Hit on J31821456 (fnet3d joint nucl, A40 48GB): 45 GB allocated +
2.4 GB free could not fit a 3 GB cat at unet3d_base.forward:195. The
host-RAM mmap_preload fix landed; this is the GPU-side counterpart.
PyTorch's own OOM message explicitly recommends this setting. No
known regressions.

indices * 8 samples = 48 GPU samples; joint at the same batch_size=48
ran 48 indices * 8 samples = 384 GPU samples, an 8x inflation.

Hit on J31821456 (gpu-c-1, A40 48GB): unet3d_base.forward:195 cat
needed a 3 GiB tensor, exactly the size of (384, 64, 32, 64, 64) at
the first decoder skip-concat. Single-set fnet3d on the same A40s
(e.g. J31065161 TOMM20 1d 19h, J31065163 MEMB 2d 2h) did fit because
their effective batch was 48, not 384.

Set batch_size=6 in the shared _hcs_init_args anchor of all four
joint fnet3d_paper leaves (er, mito, membrane, nucleus). Effective
GPU batch is now 48 — equivalent to single-set. Lead leaf carries the
full rationale; the other three reference it.

Other joint configs (celldiff, unetvit3d) use batch_size=4 with
num_samples=2, already accounting for the joint semantics; this
commit aligns fnet3d with that convention.

Subject: [PATCH 268/311] fix(dynacell): joint fcmae batch_size 32->8 (CUDA OOM
 risk)

Same BatchedConcatDataModule semantic as the prior fnet3d fix
(7a884b56): joint mode does not divide batch_size by num_samples,
so the four joint fcmae_vscyto3d_{pretrained,scratch} leaves on
nucleus and membrane were running at 4x the intended GPU batch
(32 indices * num_samples=4 = 128 samples per DDP rank, vs single-
set's effective 32). Even on H100/H200 with FCMAE's larger spatial
[20, 600, 600] patches, that headroom is not available.

Drop batch_size from 32 to 8 in the shared _hcs_init_args anchor of
all four joint fcmae leaves so 8 * 4 = 32 GPU samples per DDP rank,
matching single-set's effective batch.

Subject: [PATCH 269/311] fix(dynacell): hardware_4gpu profile now 512G +
 H100/H200-only

Two changes after the mmap_preload BasicIndexer fix (6ec0d6f7) made
the prior 1024G/A40-permitting profile obsolete:

1) mem 1024G -> 512G. With per-channel BasicIndexer reads, joint
   cell.zarr + A549 preload peaks at ~185 GB (was ~432 GB pre-fix).
   512G gives ~325 GB of headroom for worker/validation transients.
   Single-set workloads peak at ~110 GB of the cap.

2) constraint "h100|h200|a40|a6000|l40s" -> "h100|h200". A40/A6000/L40S
   (48 GB VRAM) leave no headroom for FCMAE/UNeXt2 activation peaks
   on 20*600*600 patches; in practice these jobs have always landed on
   H100/H200 anyway. A100 exclusion is preserved (NCCL hangs on this
   cluster's A100 partition). Leaves that intentionally want the
   smaller cards must opt out via
   `--override launcher.sbatch.constraint=h100|h200|a40|a6000|l40s`.

Subject: [PATCH 270/311] chore(dynacell): point SEC61B fcmae_pretrained
 predict configs at ep 123

J31523022 (FCMAE_VSCyto3D_Pretrained_iPSC_SEC61B_ws8500) was scancelled
at 3d 1h elapsed after a 49-epoch plateau confirmed by wandb. Best
checkpoint is ep 123, val_loss 0.40979.

Replace the four /TODO_FILL_BEFORE_SUBMIT placeholders in the SEC61B
fcmae_vscyto3d_pretrained predict leaves (ipsc_confocal +
a549_mantis_{denv,mock,zikv}) with the run_root-level hardlink alias
best_ep123_val0.40979.ckpt. The underlying epoch=123-step=32736.ckpt
is also preserved in checkpoints_frozen_ep123_20260501_004946/ on
project storage so future ModelCheckpoint top-K eviction can't lose
it.

Subject: [PATCH 271/311] chore(dynacell): point Memb fcmae_scratch predict
 configs at ep 136

J31710718 (FCMAE_VSCyto3D_Scratch_iPSC_Membrane) was scancelled at
1d 11h elapsed after a 27-epoch plateau confirmed by wandb. Best
checkpoint is ep 136, val_loss 0.39590.

Replace the four /TODO_FILL_BEFORE_SUBMIT placeholders in the
membrane fcmae_vscyto3d_scratch predict leaves (ipsc_confocal +
a549_mantis_{denv,mock,zikv}) with the run_root-level hardlink alias
best_ep136_val0.39590.ckpt. The underlying epoch=136-step=42744.ckpt
is also preserved in checkpoints_frozen_ep136_20260501_005505/.

Note in each leaf: the pretrained variant (J31795524, ep 194 = 0.37878)
outperforms scratch by 4.3% on the same data; downstream eval should
prefer the pretrained configs unless ablating against the scratch
baseline is the goal.

Subject: [PATCH 272/311] fix(dynacell): consistent 512G mem across 8 fnet3d
 a549/joint leaves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Align launcher.sbatch.mem to 512G across all eight fnet3d_paper
training leaves on a549/joint workloads (er, mito, membrane, nucleus
× a549_mantis, joint_ipsc_confocal_a549_mantis). The four a549-only
leaves either had no override (default 256G) or carried a stale
"cell.zarr-backed" comment from when they were generated from the
iPSC template; the four joint leaves were already at 512G. Same
comment block on each leaf documents the post-BasicIndexer-fix peak
(75 GB single-set / 185 GB joint) and the headroom rationale.

The a549-only leaves use HCSDataModule directly (no BatchedConcat
inflation), so they keep batch_size=48 which divides internally to 6
dataloader indices * 8 num_samples = 48 GPU samples — equivalent to
the joint leaves' batch_size=6 effective.

Subject: [PATCH 273/311] feat(dynacell): submit script for 8 fnet3d a549/joint
 training jobs

Bash wrapper that submits fnet3d_paper training for all four
organelles on both a549-only and joint train sets. Header documents
the four upstream fixes/audits that the eight leaves rely on so the
script's intent is recoverable from git alone:

  * mmap_preload BasicIndexer (commit 6ec0d6f7)
  * PYTORCH_ALLOC_CONF=expandable_segments:True (commit d97c23b7)
  * batch_size=6 in joint _hcs_init_args anchor (commit 7a884b56)
  * 512G mem in launcher.sbatch.mem on all eight (commit 52b53d5e)

Usage:
  bash applications/dynacell/tools/submit_fnet3d_a549_and_joint.sh

Subject: [PATCH 274/311] chore(dynacell): point Nucl fcmae_scratch predict
 configs at ep 80

J31710710 (FCMAE_VSCyto3D_Scratch_iPSC_Nucleus) was scancelled at
1d 8h elapsed after a 49-epoch plateau (last 20 epochs all 0.396-
0.398, never beat ep 80's 0.39342).

Replace the four /TODO_FILL_BEFORE_SUBMIT placeholders in the
nucleus fcmae_vscyto3d_scratch predict leaves (ipsc_confocal +
a549_mantis_{denv,mock,zikv}) with the run_root-level hardlink alias
best_ep80_val0.39342.ckpt. The underlying epoch=80-step=25272.ckpt
is also preserved in checkpoints_frozen_ep80_<ts>/ on project
storage.

Note in each leaf: pretrained variant (J31475094, ep 89 = 0.39215)
slightly edges scratch; downstream eval should prefer the pretrained
configs unless ablating against the scratch baseline.

After this commit, no predict config under applications/dynacell/
configs/benchmarks/virtual_staining/ has a TODO/FIXME/TBD ckpt_path
placeholder.

Subject: [PATCH 275/311] fix(dynacell): predict_local_*.sh fail fast on
 placeholder ckpt_path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both predict_local_ipsc.sh and predict_local_a549.sh used to plow
through compose + Lightning init even when the leaf's
model.init_args.ckpt_path was still /TODO_FILL_BEFORE_SUBMIT/...,
producing a confusing FileNotFoundError several minutes in (after
zarr-buffer prep, model graph build, etc).

Add a one-shot pre-flight that reads ckpt_path from the leaf YAML
and exits with a clear diagnostic before any compose/run work
happens:

    error: ckpt_path is still a placeholder: /TODO_FILL_BEFORE_SUBMIT/...
           set a real path in: <leaf path>

Also catches "valid path that doesn't exist on disk" (typoed path,
deleted ckpt) with the same clear message. Both scripts print the
resolved path on success ([ckpt] /hpc/.../best_epXXX_*.ckpt) for
provenance. predict_local_a549.sh validates every leaf in the batch
up-front, so a bad leaf doesn't only surface partway through the
multi-plate run.

Implementation: extend the existing META extraction (which already
reads launcher.run_root + launcher.job_name) to also pull
model.init_args.ckpt_path in the same `uv run python` call — adds
zero subprocess overhead.

Subject: [PATCH 277/311] fix(dynacell): joint fcmae batch_size 32->8 for ER +
 MITO

Extends c793da18 (nucl + memb) to the remaining four joint fcmae
leaves on ER (SEC61B) and MITO (TOMM20). Same BatchedConcatDataModule
semantic: joint mode does not divide batch_size by num_samples, so
the prior batch_size=32 ran at 4x the intended GPU batch
(32 * num_samples=4 = 128 samples/rank vs single-set's effective 32).

All four leaves now match the running NUCL/MEMB configs at
batch_size=8 (8 * 4 = 32/rank), with the explanatory comment ported
across.

Fixes wrong per-plate GT path structure, adds all 12 eval calls (was 2),
correct channel names per organelle, and enables feature metrics with
seg_cleaned zarrs now available for A549.

Covers celldiff_iterative, fcmae_vscyto3d_pretrained, and fcmae_vscyto3d_scratch.
fcmae_scratch omits nucleus (no predictions available). All calls use
seg_cleaned zarrs and feature metrics, matching the unetvit3d_a549 pattern.

prepare_data sized the mmap buffer at ``len(positions) * T_pos0`` and
indexed each FOV write at ``data_buf[i*T:(i+1)*T]``, which silently
worked only when every FOV had the same T as positions[0]. The a549
mantis pooled zarrs mix conditions with different frame counts —
SEC61B_all (14 FOVs at T=7 + 14 at T=10) and TOMM20_all (T=5 + T=10) —
so the assignment crashed at the first FOV with a different T. NUCL
(H2B_all) and MEMB (CAAX_all) pools were uniformly T=10 and worked
by coincidence.

Introduce ``_fov_t_offsets`` to build a per-position cumulative offset
table once from zarr metadata; size the buffer as ``sum(T_i)`` and
write ``data_buf[offsets[i]:offsets[i+1]]``. The fg_mask buffer is
sized off the same data-array offsets table because both layouts must
match row-for-row (silent drift would mis-align mask with data).
``_open_mmap_buffer`` and ``_fov_views`` now consume the same offsets
helper so reads and writes agree, even when the optional ``array_key``
override (used for fg_mask dtype/spatial dims) names a different key.

Subject: [PATCH 281/311] refactor(viscy-data): compute mmap T offsets once per
 setup_fit

Hoist the cumulative offsets table to _setup_fit so it is built once
and threaded through _open_mmap_buffer and _fov_views, replacing two
to four redundant per-call recomputations (one for the data buffer,
plus one each for fg_mask when configured). _fov_views can be a plain
@staticmethod again now that it does not need self.array_key.
test_mmap_preload_heterogeneous_t calls HCSDataModule._fov_t_offsets
directly instead of hand-rolling the offsets loop, so a later change
to the offset semantics cannot drift between impl and assertion.

Subject: [PATCH 282/311] =?UTF-8?q?feat(dynacell):=20A549=20eval=20scripts?=
 =?UTF-8?q?=20for=20all=205=20models=20=E2=80=94=20flat=20mantis=5Fv1=20la?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rewrites fnet3d/unetvit3d/celldiff a549 scripts to use the flat
mantis_v1/test/{ORGANELLE}_{infection} layout and adds seg_cleaned
paths + compute_feature_metrics=true. Adds new scripts for unext2
(fcmae_vscyto3d_scratch) and vscyto3d (fcmae_vscyto3d_pretrained).

Subject: [PATCH 283/311] fix(viscy-data): skip bs%num_samples check for
 BatchedConcat children
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

HCSDataModule._train_transform raised when batch_size % num_samples
!= 0 because HCSDataModule.train_dataloader divides batch_size by
num_samples and would round down silently. BatchedConcatDataModule
overrides train_dataloader to use batch_size as-is — it loads N
indices, each yielding num_samples patches per the child transform,
so N indices * num_samples patches = effective per-step samples and
divisibility is irrelevant. The check still fired during the child's
setup_fit, blocking joint configs that intentionally pick (N,
num_samples) pairs hitting a target sample count without divisibility
(e.g. fnet3d_paper joint at bs=6, num_samples=8 → 48 samples per
step, matching the single-set fnet3d's 48//8=6 indices * 8 patches
behaviour).

BatchedConcatDataModule.setup now flags each child before delegating
to ConcatDataModule.setup, and the check honors that flag.
ConcatDataModule (the parent class) keeps the original constraint
because *its* train_dataloader does divide.

Subject: [PATCH 284/311] refactor(viscy-data): tighten joint-divisibility test
 + comment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Trim the inline comment on the gated divisibility check to a single
line — the why was already covered by the helper docstring on
BatchedConcatDataModule.setup, the longer block was rehashing what
the surrounding code already shows.

Extend the existing _make_dm helper in test_combined.py with optional
augmentations + source/target channel overrides instead of inlining
a closure that re-derives the same construction. Drops the redundant
f-string assertion message; pytest already prints the failing value.

Subject: [PATCH 285/311] feat(dynacell): a549-trained nucleus fnet3d_paper
 predict configs

Mirrors the existing nucleus/fnet3d_paper/ipsc_confocal/predict__*.yml
layout into the sibling a549_mantis/ leaf so the a549-trained
checkpoint produced by job 31858491 (FNet3DPaper_A549_NUCL, completed
2026-05-03 with val_loss=0.2088 at epoch 293) has predict configs for
all four test sets used by the evaluation pipeline.

Outputs are suffixed _a549trained to keep them distinct from the
existing ipsc-trained predictions in dynacell/{ipsc,a549}/predictions/
so downstream eval configs can reference the pair side-by-side.
A549 leaves keep the dataset_ref.target=h2b override the ipsc-trained
versions use, since the a549 manifest keys nucleus by gene.

Subject: [PATCH 286/311] docs: explain joint vs single-set training batch
 semantics

Document the BatchedConcatDataModule.train_dataloader override that
uses batch_size as-is (vs HCSDataModule and the parent ConcatDataModule
which divide by train_patches_per_stack), the resulting
joint.batch_size = single_set.batch_size / num_samples sizing rule,
and the divisibility check that is now suppressed for joint children
(commit 5a2a3467). Captured here because I misread this in two
separate review passes during the fnet3d joint resubmission and
shipped a wrong "FCMAE joint is 4x undersized" claim before
re-tracing the dataloader code; the table + verified examples should
prevent the same mistake on the next pass.

 The dynacell launcher (`applications/dynacell/tools/submit_benchmark_job.py`) already emits `--ntasks-per-node` correctly; this note is for hand-written scripts (e.g., `applications/cytoland/examples/configs/*/run_*.slurm`).
 
+### Joint vs single-set training batch semantics
+
+`HCSDataModule` and `BatchedConcatDataModule` produce the same number of GPU samples per training step — but the YAML `batch_size` value that gets there is **different by a factor of `num_samples`**. Easy to misread either by skimming.
+
+| DataModule | `train_dataloader` divides by `num_samples`? | Samples per step |
+|---|---|---|
+| `HCSDataModule` (single-set) | yes (`hcs.py` `train_dataloader`) | `batch_size` |
+| `ConcatDataModule` (parent class) | yes (`combined.py` `train_dataloader`) | `batch_size` |
+| `BatchedConcatDataModule` (joint) | **no** (`combined.py` overrides; uses `batch_size` as-is) | `batch_size * num_samples` |
+
+To match the same effective per-step samples between a single-set and a joint config, **set `joint.batch_size = single_set.batch_size / num_samples`**.
+
+Examples (verified against the `applications/dynacell/configs/benchmarks/virtual_staining/_internal/shared/model/data_overlays/` overlays + their joint leaves):
+
+- FCMAE (`fcmae_vscyto3d_*`): single-set `batch_size: 32, num_samples: 4` → joint `batch_size: 8, num_samples: 4` → both yield **32 samples/step**.
+- FNet3D (`fnet3d_paper`): single-set `batch_size: 48, num_samples: 8` → joint `batch_size: 6, num_samples: 8` → both yield **48 samples/step**.
+
+`HCSDataModule._train_transform` enforces `batch_size % num_samples == 0` for single-set use because `train_dataloader` would otherwise round down silently. The check is suppressed for `BatchedConcatDataModule` children via the `_is_batched_concat_child` flag set in the wrapper's `setup()` — joint configs are free to pick any `(batch_size, num_samples)` pair as long as the product is the desired sample count. **Do not** "fix" a joint config by raising `batch_size` to satisfy the divisibility rule; it would multiply effective samples by `num_samples`.
+
+When in doubt, read both `train_dataloader` overrides directly — they are short. Don't infer from comments alone.

Subject: [PATCH 287/311] refactor(dynacell): unify predict_local script across
 train sets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

predict_local_{a549,ipsc}.sh hardcoded ipsc_confocal as the train set,
so a549-trained or joint-trained models could not reuse them — the
new a549-trained nucleus fnet3d_paper predict configs (commit
4951fc01) had no driver. Collapse both into one
predict_local.sh that takes <organelle> <model> <train_set> <test_set>
and accepts shorthand (ipsc | a549 | joint), with the same compose +
ckpt-existence preflight + parallel batching.

Single-leaf (test_set=ipsc) and per-plate (test_set=a549, glob over
the 3 a549_mantis treatments) paths unify cleanly because the leaf
discovery is just a glob; the existing parallel batcher handles N=1
as a degenerate case.

Old scripts removed per the project's "avoid backwards compatibility"
convention (CLAUDE.md). No callers in applications/, docs/, or
adjacent tools/ scripts.

Subject: [PATCH 288/311] docs(dynacell): add model name convention reference
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Translates between code names (used in YAML config keys, prediction
zarr filenames, eval pipeline keys, W&B run names) and paper /
display names (UNeXt2, VSCyto3D, FNet3D, UNetViT3D, CELL-Diff).
Also explains the eval-pipeline directory naming convention which
keys directories by paper name (eval_unext2_membrane → predictions
from fcmae_vscyto3d_scratch, eval_vscyto3d_membrane →
fcmae_vscyto3d_pretrained), so cross-references between training
configs and eval results are unambiguous.

+## Model name conventions
+
+Code names (used in YAML config keys, prediction zarr filenames, eval pipeline keys, W&B run names) differ from the paper names. When writing/reading anything that crosses the code/paper boundary (figures, tables, Confluence pages, manuscripts), translate:
+
+| Code name (config / zarr / W&B) | Paper / display name |
+| --- | --- |
+| `fcmae_vscyto3d_scratch` | **UNeXt2** |
+| `fcmae_vscyto3d_pretrained` | **VSCyto3D** (FCMAE-pretrained is the canonical VSCyto3D variant) |
+| `unext2` | UNeXt2 (legacy zarr prefix; superseded by `fcmae_vscyto3d_scratch`) |
+| `vscyto3d` | VSCyto3D (display key in Dihan's eval pipeline; sources `*_fcmae_vscyto3d_pretrained` predictions) |
+| `unetvit3d` | UNetViT3D |
+| `fnet3d_paper` | FNet3D |
+| `celldiff` | CELL-Diff (variants: `iterative`, `sliding_window`, `denoise`/Mean Predictor) |
+
+Eval-pipeline directory naming (`/hpc/projects/virtual_staining/training/dynacell/{ipsc,a549}/evaluations/eval_<model>_<organelle>[_<plate>]`) uses the **paper key** (`unext2`, `vscyto3d`, `fnet3d`, `unetvit3d`, `celldiff_*`), not the config key. So `eval_unext2_membrane` maps to the `fcmae_vscyto3d_scratch` predictions, `eval_vscyto3d_membrane` maps to `fcmae_vscyto3d_pretrained`.

Subject: [PATCH 289/311] test(dynacell): fcmae er joint smoke configs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Single-GPU and 4-GPU DDP smoke variants for the fcmae_vscyto3d_scratch
ER joint leaf, mirroring the existing celldiff and fnet3d_paper smoke
patterns under the same er/.../joint_*/ tree. The 4-GPU variant was
the probe that reproduced the heterogeneous-T mmap_preload bug
(commit 10e5c16e) on a small SEC61B_test48 + a549 SEC61B_all pair —
keep it in tree as a regression check the next time someone touches
prepare_data or BatchedConcatDataModule.

Subject: [PATCH 290/311] chore(dynacell): handoff script for a549-only fcmae
 resubmits
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Operational script for delegating the 4 a549-only ER/MITO FCMAE
trainings to a different submitter when the primary user's fairshare
is pushing them hours-to-days into the future. The script checks
that the venv exists and that HEAD contains the heterogeneous-T fix
(dcfedfd2) before submitting via submit_benchmark_job.py — without
that commit the jobs crash again at prepare_data on the mixed-T
SEC61B_all and TOMM20_all pools.

The header documents the one-time per-user setup (clone, venv, wandb
login, group-write access) and warns the primary submitter to
scancel any prior pending submissions before this runs so they do
not duplicate against the same run_root + wandb project.

+# Handoff script: resubmit the 4 a549-only ER/MITO FCMAE training jobs
+# from a higher-fairshare account.
+#
+# These 4 leaves (er + mito × scratch + pretrained, single-store
+# a549_mantis training) initially failed under @alex.kalinin's account
+# because the mmap_preload path assumed uniform T per FOV; the a549
+# mantis pooled stores mix T=5/7/10 per condition. Fix is on
+# dynacell-models @ dcfedfd2 ("refactor(viscy-data): compute mmap T
+# offsets once per setup_fit") — that commit (or later) MUST be at
+# HEAD or jobs will crash again at prepare_data.
+#
+# Why a different submitter: alex.kalinin is currently #3 by cluster
+# NormUsage, so fairshare is pushing the resubmits ~7-58 hours into
+# the future. Submitting from a less-used account gets better
+# priority.
+#
+# Pre-flight (run once per user, not per script invocation):
+#
+#   1. Clone / pull the repo onto your /hpc/mydata/<user>/ checkout,
+#      switch to dynacell-models, and verify the fix is in:
+#
+#         git checkout dynacell-models && git pull
+#         git log --oneline -5 | grep dcfedfd2  # must show the commit
+#
+#   2. Set up the venv if not already (uv lives behind Lmod on this
+#      cluster — load it first):
+#
+#         ml uv
+#         uv venv -p 3.13
+#         uv sync --all-packages --all-extras
+#
+#   3. Wandb credentials (configs use WandbLogger -> czi.wandb.io,
+#      project=dynacell, entity=computational_imaging):
+#
+#         wandb login --relogin   # paste a key with that entity
+#
+#   4. Confirm group write access on the prod output root:
+#
+#         touch /hpc/projects/comp.micro/virtual_staining/models/dynacell/a549_mantis/.write_test \
+#           && rm /hpc/projects/comp.micro/virtual_staining/models/dynacell/a549_mantis/.write_test
+#
+#   5. Coordinate with alex.kalinin so HE cancels job IDs 31910346,
+#      31910356, 31910360, 31910371 BEFORE this script runs — those
+#      target the same run_root and wandb runs would collide.

 predict configs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Best val checkpoint from job 31822574 (epoch 119, loss/validate=0.2722,
146 epochs total — plateaued from ep 119 onward). Mirrors the existing
nucleus/fnet3d_paper/a549_mantis predict pattern: ipsc-test leaf has no
target override, a549 leaves override dataset_ref.target to gene-keyed
`caax`.

Subject: [PATCH 292/311] feat(dynacell): a549-trained membrane fnet3d_paper
 predict configs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Best val checkpoint from job 31858488 (epoch 281, loss/validate=0.3143,
289 epochs total — 7-epoch plateau). Mirrors the existing
nucleus/fnet3d_paper/a549_mantis predict pattern: ipsc-test leaf has no
target override, a549 leaves override dataset_ref.target to gene-keyed
`caax`.

Subject: [PATCH 293/311] feat(dynacell): a549-trained nucleus fcmae_scratch

Best val checkpoint from job 31822562 (epoch 110, loss/validate=0.8345,
135 epochs total). Mirrors the existing membrane/fcmae_vscyto3d_scratch/
a549_mantis predict pattern: ipsc-test leaf has no target override, a549
leaves override dataset_ref.target to gene-keyed `h2b`.

From e5abfe22c976f696c7c3138634d3c4a72264ec62 Mon Sep 17 00:00:00 2001
From: Alexandr Kalinin <alxndrkalinin@users.noreply.github.com>
Date: Mon, 4 May 2026 17:31:03 -0700
Subject: [PATCH 294/311] refactor(dynacell): unify predict_batch script across
 train/test sets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bring predict_batch.sh to parity with predict_local.sh: accept
<train_set> and <test_set> args (with ipsc/a549/joint shorthand)
instead of hardcoding ipsc-trained → A549-mantis prediction.
Renamed from predict_all_a549.sh — the old name lies once test_set
is variable.

Verified with --dry-run on the original use case (er fnet3d_paper
ipsc a549) and on cases that weren't possible before (nucleus
fnet3d_paper a549 a549, ... a549 ipsc). submit_benchmark_batch.py
itself was already test-set-agnostic; this is a wrapper-only change.

Subject: [PATCH 295/311] feat(dynacell): save single-cell embeddings with
 FOV/timepoint metadata

Track FOV name and timepoint per cell across CellProfiler, DINOv3, and
DynaCLR embeddings, then save as .npz to embeddings/ under the eval output
dir. Also redirects OUT_ROOT to evaluations_with_embeddings and enables ER
organelle evals (disabling membrane/nucleus) across all 5 model eval scripts.
Add viscy-data[mmap] extra to dynacell pyproject.

Subject: [PATCH 296/311] feat(dynacell): add CellDiff A549 mantis predict
 configs; reduce batch size to 2

Add predict YAMLs for membrane and nucleus CellDiff across mock/denv/zikv
infection variants. Reduce batch_size from 4 to 2 in the joint
ipsc+confocal+a549+mantis train configs for both membrane and nucleus.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Best val checkpoint from job 31822558 (epoch 134, loss/validate=0.8142,
178 epochs total). Fills the last gap in the (Nucleus|Cell Membrane) ×
(F-net|UNeXt2 scratch|UNeXt2 FCMAE) a549-trained predict matrix; only
the FCMAE Cell Membrane variant remains. ipsc-test leaf has no target
override, a549 leaves override dataset_ref.target to gene-keyed `h2b`.

Subject: [PATCH 298/311] docs(dynacell): document prediction zarr naming
 convention

Adds a "Prediction zarr naming convention" section to dynacell/CLAUDE.md
covering the iPSC / A549 / Joint training-set infix scheme and the
historical SEC61B/TOMM20 double-underscore form. Settles the naming for
forthcoming joint-trained predicts as `_jointtrained` (decided 2026-05-04).

 Eval-pipeline directory naming (`/hpc/projects/virtual_staining/training/dynacell/{ipsc,a549}/evaluations/eval_<model>_<organelle>[_<plate>]`) uses the **paper key** (`unext2`, `vscyto3d`, `fnet3d`, `unetvit3d`, `celldiff_*`), not the config key. So `eval_unext2_membrane` maps to the `fcmae_vscyto3d_scratch` predictions, `eval_vscyto3d_membrane` maps to `fcmae_vscyto3d_pretrained`.
+
+## Prediction zarr naming convention
+
+Set by `trainer.callbacks[…HCSPredictionWriter].init_args.output_store` in each leaf of `applications/dynacell/configs/benchmarks/virtual_staining/<organelle>/<model>/<train_set>/predict__*.yml`. The infix between model name and the optional plate condition flags the **training set** of the source model:
+
+| Trained on | Test set | Filename |
+| --- | --- | --- |
+| iPSC | iPSC | `<org>_<model>.zarr` |
+| iPSC | A549 plate | `<org>_<model>_<cond>.zarr` |
+| A549 | iPSC | `<org>_<model>_a549trained.zarr` |
+| A549 | A549 plate | `<org>_<model>_a549trained_<cond>.zarr` |
+| Joint (iPSC + A549) | iPSC | `<org>_<model>_jointtrained.zarr` |
+| Joint (iPSC + A549) | A549 plate | `<org>_<model>_jointtrained_<cond>.zarr` |
+
+Where `<org>` is `nucl` / `memb` / `sec61b` / `tomm20`, `<model>` is the **code name** from the table above (e.g. `fcmae_vscyto3d_scratch`, `fnet3d_paper`), and `<cond>` is `mock` / `denv` / `zikv`. The (no-infix) iPSC-trained naming is historical baggage from before joint/A549 training existed; don't add a `_ipsctrained` infix retroactively. Output dirs: iPSC test predictions land under `ipsc/predictions/`, A549 plate predictions under `a549/predictions/`, regardless of training set.
+
+Caveat: Dihan's earlier ER + Mito iPSC-trained zarrs use a legacy `<gene>_<model>__<gene>_<cond>.zarr` shape (e.g. `sec61b_fcmae_vscyto3d_scratch__sec61b_mock.zarr`, double-underscore + redundant gene prefix). New leaves should follow the table above; do not propagate the legacy form.

+# Architecture: BatchedConcatDataModule pools D1+D2+D3 cropped zarrs
+# (~323 GB total) into a single shuffled dataset with one

+# NOT divided by num_samples in joint mode — bs=16 indices × num_samples=4
+# = 64 patches/step/rank × 4 ranks = 256 patches/step total.
+#
+# Backend: zarr-python with mmap_preload to /tmp. Stages all FOVs to a
+# MemoryMappedTensor on local /tmp (28 TB) during prepare_data, then
+# closes the zarr handles. DataLoader workers fork from a parent with no
+# live zarr asyncio loop and read from the mmap'd tensor — fork-safe.
+# /dev/shm (~126 GB) is too small even for the cropped 323 GB dataset.
+#
+# Cropped zarrs (zarrv3_cropped/) shrink each FOV from
+# (T, 3ch, Z=126, 2048, 2048) full-tile down to (T, 3ch, Z=50, ~1500-2048,
+# ~1300-2048) so total staging fits well under /tmp.
+#
+# Standalone (does NOT inherit finetune_a549_infected.yml) because the

Subject: [PATCH 301/311] feat(dynacell): joint-trained nucleus fcmae_scratch
 predict configs

Predict configs for J31822521 (TIMEOUT @ ep102, val 0.6448 @ ep92): joint
iPSC+A549 UNeXt2 scratch on nucleus. Covers iPSC test set + 3 a549 plates
(mock/denv/zikv); a549 leaves override target to h2b for the gene-keyed
a549 manifest. Outputs land at nucl_fcmae_vscyto3d_scratch_jointtrained{,_<cond>}.zarr
per the _jointtrained convention.

Subject: [PATCH 303/311] feat(dynacell): joint-trained membrane fcmae_scratch
 predict configs

Predict configs for J31822536 (finished @ 118 ep, val 0.3859 @ ep112): joint
iPSC+A549 UNeXt2 scratch on cell membrane. Covers iPSC test set + 3 a549
plates (mock/denv/zikv); a549 leaves override target to caax.

Subject: [PATCH 304/311] feat(dynacell): a549-trained mito fcmae_scratch
 predict configs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Predict configs for J31910360 (cancelled @ ≥113 ep): A549-only UNeXt2 scratch
on mito (TOMM20). Pinned to ep113 ckpt with val 0.7329 per the resume's
re-evaluation in last.ckpt's best_model_score block.

Carries a wandb-collision caveat: J31910360 (TOMM20) and J31910346 (SEC61B)
landed on the same node gpu-f-5 within 9 seconds and the launcher's
timestamp-derived wandb run id `20260502-204536` collided. The wandb
dashboard for that run shows the TOMM20 display name but logged metrics
align step-wise with SEC61B's training, not TOMM20's. The original-run
wandb history is therefore unrecoverable for TOMM20; the on-disk Lightning
trainer state is the source of truth.

Subject: [PATCH 305/311] feat(dynacell): a549-trained ER fcmae_scratch predict
 configs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Predict configs for J31910346 (completed cleanly @ ep199, val 0.6219 @ ep137):
A549-only UNeXt2 scratch on ER (SEC61B). Carries the same wandb-collision
caveat as the sibling TOMM20 configs: this SEC61B run shared wandb run id
`20260502-204536` with J31910360 (TOMM20) on gpu-f-5 — the wandb history
metrics actually belong to SEC61B (step-wise alignment confirms), but the
dashboard display name was overwritten by TOMM20.

Subject: [PATCH 306/311] feat(dynacell): joint-trained nucleus fnet3d predict
 configs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Predict configs for J31962520 (completed @ ep129 hitting max_steps, val
0.9709 @ ep126): joint iPSC+A549 F-net on nucleus. Covers iPSC test set + 3
a549 plates; a549 leaves override target to h2b. Note val late-stage drift
(ep127→1.05, ep128→1.28) — best-val ckpt at ep126 used for predictions.

 configs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Predict configs for J31962519 (completed @ ep129 hitting max_steps, val
0.5759 @ ep116): joint iPSC+A549 F-net on cell membrane. Covers iPSC test
set + 3 a549 plates; a549 leaves override target to caax. Note val drifted
to 0.6751 at ep128 — best-val ckpt at ep116 used for predictions.

Predict configs for J31965119 (completed @ ep392 hitting max_steps, val
0.8291 @ ep248): A549-only F-net on mito (TOMM20). Final val drifted to
0.9493 — best-val ckpt at ep248 used for predictions. Both iPSC and a549
manifests use tomm20; no dataset_ref override needed.

Subject: [PATCH 309/311] feat(dynacell): add joint-trained eval scripts and
 predict configs for all models

Add mix-trained evaluation scripts for celldiff, vscyto3d, unext2, and fnet3d
across iPSC and A549 (mock/denv/zikv) test sets, covering membrane and nucleus
targets. Also add new CellDiff predict configs for movie/iPSC sets and fix
nucleus CellDiff A549 output paths to use joint_predictions/.

Subject: [PATCH 310/311] feat(dynacell): joint-trained nucleus fnet3d eval
 scripts (full metrics)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fills the two missing slots in the 6 train-set × 2 organelle FNet3D
membrane/nucleus eval matrix: joint→iPSC nucleus and joint→A549
nucleus (×3 infections). Predictions already existed under
{ipsc,a549}/joint_predictions/, but no eval scripts had been wired up.

Distinct from upstream's run_eval_mix_trained_a549_pred_nucleus_*.sh,
which run pixel-only (compute_feature_metrics=false, no seg path).
These compute all three metric tiers (pixel + mask + DynaCLR feature
metrics) for the supplementary table comparing FNet3D across training
pools.

Slurm runner submits the two scripts as a 2-task array so the iPSC
eval (1 condition) and the A549 eval (3 infections) run in parallel
on h100/h200/a100.

Subject: [PATCH 311/311] feat(dynacell): joint-trained membrane unext2 eval
 scripts (full metrics)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the UNeXt2 (fcmae_vscyto3d_scratch) counterpart to the FNet3D
joint-trained membrane evals, completing the model coverage needed for
the 3-pool × 2-test comparison table in the paper appendix.

UNeXt2 joint membrane predictions already existed; only the eval
scripts were missing. Same shape as the joint nucleus runner: a 2-task
slurm array — task 0 = iPSC test, task 1 = A549 test × {mock, denv,
zikv} — with full metric tiers (pixel + mask + DynaCLR features).
