It was NOT realised: sdf.to_glsl() emitted GLSL for a tree, emit_kernel emitted WGSL from a scalar function's SOURCE TEXT, and THE TWO NEVER MET -- so RealtimeSession.payload('shader') carried whatever kernel_src the caller passed: a shader written by hand, about a scene the engine never saw. That is drift by construction. mind.sdf_dialect(tree, dialect) walks the SAME tree that _eval walks and emits map(p) -> distance in wgsl | glsl | c_f64 | c_f32, and payload('shader') now emits the SCENE's own map(). THE BAR IS EXECUTED: WGSL cannot run here, so mind.sdf_validate_c COMPILES the C twin with cc and RUNS it against the Python _eval. MEASURED on a scaled smooth-union of a translated sphere and a rotated box, 200 points: c_f64 agrees to 6.7e-16 and is NOT bit-identical -- because np.linalg.norm rescales to avoid overflow and sums in a different order than sqrt(x*x+y*y+z*z), so the emitted C computes the same FUNCTION by a different summation (K8's scalar kernel WAS bit-identical, because it emitted the same expression). c_f32 differs by 3.3e-07, which IS the tolerance a WGSL port is judged against -- and the `f` literal suffix is LOAD-BEARING: unsuffixed, a C literal is a DOUBLE and the whole expression evaluates in double before truncating, so the first table published an optimistic 2.83e-07. An audit found it because holographic_emit's dialect table used `f` and this one did not: TWO TABLES FOR ONE CONCEPT WILL DISAGREE, AND THE DISAGREEMENT WILL BE A BUG IN ONE OF THEM. A test now pins the shared dialects to agree, field by field. And mind.sdf_dialect takes an SDF tree OR ITS DSL TEXT, because a live tree does not survive JSON and parse_dsl(to_dsl(t)) round-trips to 0.0e+00 -- the kernel is text; so is the scene. THREE KEPT NEGATIVES: (1) `menger` and `repeat` fold the domain ITERATIVELY -- unrolling makes the shader's size a parameter -- and `twist`/`displace` are inexact distance warps; all four are REFUSED by name, and mind.sdf_emit_coverage asserts emitted + refused == every one of the 18 node kinds, because a gap there is a shader that silently omits geometry. (2) `scale` is not `p / s`, it is `map(p / s) * s`; drop the outer factor and the shape renders correctly with WRONG DISTANCES, and a raymarcher oversteps it. (3) WGSL IS NOT C: it infers a local's type with `let`, and rejects `vec3 name = ...`. The first emitter wrote the C form for every dialect and the structural test -- which checked only the signature and the brace balance -- passed the invalid WGSL. An emitted shader is not a rendered image: this validates the DISTANCE FUNCTION, not WGSL's precision rules, its fast-math latitude, or whether it compiles.. @@ -2086,6 +2201,14 @@ import lecore; m=lecore.UnifiedMind(dim=256,seed=0); print('mainImage' in m.to_s *talk a 3-D scene into being, then adjust its named objects in words, and render or simulate it.* +### Animate the scene document (keyframes -> frames -> GIF) +keyframes in, frames out, optionally an animated GIF -- the see->fix loop for MOTION.

Needs a MEASUREMENT first (does any render path clear should_offload's data/intensity bars?) -- +building a seam nothing can pay for is the failure mode this project keeps on record. +W3: place_work's unit oracle knows machine-model units; the new render work registered none, so it cannot +reason about render jobs at all. + +## BRANCH MERGE (J-3D scene/asset/objectref + catalog split) -- A WRONG-BASE MERGE, AND WHAT IT COST + +Moose: a branch based on a version PRIOR to the last merge, to be brought up to speed and merged. + +### THE SHAPE OF THE PROBLEM: the fork point was an INTERMEDIATE snapshot nobody has +The branch carried the UnifiedMind split and the code-health modules but PREDATED the entire GPU/agent layer. +So neither of our two known trees is its base. Relative to the newest common tree it appears to DELETE 48 +files and hundreds of methods, when in truth it never had them. THIS IS THE CENTRAL HAZARD OF A WRONG-BASE +MERGE: age is indistinguishable from intent, and every standard tool takes it as intent. + * `git merge-file --diff3` merged 46 files with only 3 textual conflicts -- and silently removed place_work, + declare and agent_loop, because a one-sided removal relative to the WRONG base is a clean, conflict-free + delete. A green merge is not a correct merge. + * `--union` does NOT fix it: union resolves CONFLICTING hunks by keeping both sides, but a clean one-sided + deletion never conflicts, so it is applied either way. Measured, not assumed. + * THE CORRECT SEMANTIC when the base is wrong is ADD-ONLY: take their addition hunks, never their deletions. + Implemented by filtering the unified diff to hunks with no '-' lines. + +### WHAT ADD-ONLY COSTS, AND THE SWEEPS THAT PAID IT +An addition-only filter drops any hunk that MIXES an addition with a change -- so it loses signature edits and +helpers defined next to them. Three sweeps found every instance, and each sweep is reusable: + 1. FACULTY SURFACE (hash every callable on UnifiedMind in all three trees): found 10 lost scene faculties. + 2. MODULE SYMBOLS (ast walk, public AND private): found _view_transform, _fit_to, _PlacedEval, render_preview, + _selftest_hdr. Private helpers matter -- a body referencing an undefined name compiles fine and fails at + runtime with a bare NameError. + 3. SIGNATURE PARAMETERS (compare arg-name sets per function): found render_scene_document/_place/ + scene_to_render missing view= and affine=, and walk() missing stream=. This is the sneakiest class: the + BODY arrived (pure addition) while the DEF LINE did not (a modification), leaving code that references a + parameter its signature never declares. +Where a file's symbol sets matched exactly between branch and merge, taking their whole file was provably safe +and was done instead of further patching (scene_render, p07, run_selftests). + +### THE ONE A SURFACE HASH COULD NOT SEE: a REORGANISED registry +The branch also split holographic_catalog.py into six parts -- authored against its PRE-FORK catalog. Taking +that split wholesale silently dropped THIRTY capability registrations: the entire GPU/agent/compute layer +(place_work, wgsl_*, declare, resource policy, agent loop, ...). The FACULTIES were all present and callable, +so every faculty-level check passed. NO AUDIT CAUGHT IT: catalog_gaps and skill_lint verify that REGISTERED +capabilities have homes and runnable examples, and neither can see an ABSENCE. Only a test asserting that a +specific phrasing still routes ("where should this work run") noticed. +LESSON, now the rule: WHEN A REGISTRY IS REORGANISED ON A BRANCH, DIFF THE RESULTING NAME SET AGAINST THE +BASE, NEVER JUST THE FILE. Restored all 30 at the end of the last part (tie-break order preserved), and the +catalog is now provably the union: 2566 = pre-merge 2514 + branch 2455, zero lost from either parent. + +### DEFECTS IN THE BRANCH ITSELF (each confirmed failing on the branch standalone) + * wiring_report --check (a CI GATE) failed: all six catalog parts reported dark, because + `from PKG import MODULE` is INVISIBLE to the audit -- the same facade-import lesson that once cost a + 43-import sweep. Fixed the import style AND declared the parts as registry body in EXEMPT. + * TWO new name collisions: `make_shape` (new SDF entry vs the incumbent holographic_vision) and a six-way + `register` across the catalog parts. Both resolved by RENAMING THE NEWER ARRIVAL (make_sdf_shape, + register_pNN) rather than growing a budget whose own contract says it may shrink and must never grow. + register_pNN also matches the unified split's precedent of distinct _UnifiedPartNN names, and makes a + traceback name its own part. The branch's part-registration test was updated to pin THAT contract. + * A ROUTING PIN broke: the branch's new "Describe to document" shares the incumbent "Describe a scene"'s + whole vocabulary; the two tied and the decision fell act -> choose at 0.5. Additive fix (give the + incumbent its exact probe phrasing) restored act at 0.727 -- ABOVE the pre-merge 0.667. + * A duplicated __main__ guard in meshqem from the union pass, folded back to the true end of module. + +### A SECOND-ORDER EFFECT WORTH REMEMBERING: the abstain floor RISES with the catalog +Restoring the 30 capabilities pushed route_or_abstain's in-vocabulary noise floor from null_mean 2.88 to 3.49. +A correct top hit whose score never moved (4.50) went from z=1.08 (answer) to z=0.63 (ABSTAIN), breaking the +declare ladder's rung 0. The fix is to raise the TARGET (exact phrasings as aliases -> score 4.5 to 8.5, +z=3.78), never to lower the floor, which would weaken every gate that uses it. NOTE THE NEAR-MISS: the first +attempt put those aliases on the neighbouring "Mesh editing (DCC)" entry, which dispatches to `deform` -- the +ladder then resolved, but TO THE WRONG FACULTY, and only the test asserting the faculty NAME caught it. +Getting a green is not the same as getting it right. + +### Post-merge state +1340 py files compile; 2566 capabilities; 1599-method faculty surface PROVEN to be the union of both parents +(zero lost from either, by source hash). All seven gates green. Cross-burial matrix extended with the three +pins this merge discovered, so the class is guarded rather than rediscovered. Branch's 35 new tests + 147 +pinned/regression tests green; 9 generated docs regenerated and drift-checked. + +## W2/W3 CLOSED: the render arc now asks the placement layer -- and MOST of it correctly gets "no" + +W2 asked whether the new render modules need a backend=/pool= seam. MEASUREMENT FIRST, because building a +seam nothing can pay for is a failure mode already on record. Against should_offload's provisional bars +(>= 100 KB moved, >= 4.0 flops/byte): + + sdf sphere trace 256x192 / 512x384 / 1024x768 144.0 flops/byte CLEARS BOTH (by ~36x) + postfx elementwise 512x384 / 1920x1080 0.8 flops/byte refused (transfer-bound) + rasterize 50k tris 1.7 flops/byte refused + qem decimate 20k verts 5.0 flops/byte marginal -- see below + +THE ANSWER IS AN ASYMMETRY, and it is the useful result: exactly ONE render path pays for a device, and it is +the one W1 just built. Wiring backend= across the render arc -- the obvious reading of the sweep -- would have +been WRONG for postfx and the rasterizer, which are transfer-bound BY CONSTRUCTION (they read and write +everything and compute almost nothing; should_offload's own docstring says so and the numbers agree). KEPT +NEGATIVE, pinned in test_holographic_sdf so a future session cannot re-propose it from narrative. +QEM at 5.0 vs a 4.0 bar is NOT a green light: those thresholds are arithmetic from PCIe bandwidth and are +marked provisional everywhere they surface, so a 25% margin sits inside the uncertainty of an unmeasured +number. Not built, on purpose, recorded. + +W3's framing was slightly WRONG and the probe corrected it: machine_units() holds 17 HARDWARE/caching units +(simd_lanes, rt_core, t2_baked_grid...), not workload registrations, so "register a render unit" was never +the gap. The real gap was that NOTHING IN ARC B EVER CALLED THE DECISION LAYER. +BUILT sdf_trace_workload + sdf_trace_placement (holographic_wgpurun + 2 faculties): they derive +(n_bytes, flops_per_byte) FROM THE TRACE'S OWN PARAMETERS and hand them to place_work. WHY AT THIS SEAM +rather than the call site: should_offload answers honestly but only about the numbers it is GIVEN, and those +two are precisely what a caller gets wrong -- bytes TOUCHED instead of bytes MOVED, flops per PIXEL instead +of per byte -- and a wrong input yields a CONFIDENT wrong verdict. The verdict carries the numbers that +produced it so nobody re-derives them. +PINNED PROPERTY WORTH KNOWING: the trace's intensity is RESOLUTION-INDEPENDENT (both terms scale with pixel +count), so the offload question turns on MARCH DEPTH and tree cost, never on image size -- halving `steps` +halves the intensity exactly. A 'cpu' verdict on a box with no adapter is a RESULT, not a failure. +Aliases folded into the existing GPU-SDF capability rather than a sibling entry (one idea, one home); +"should i offload the render" / "where should this trace run" now top-1. Audits 0/0/0; 16 sdf tests green. + +## W4 CLOSED: the second emitter is now EXECUTED -- the "two tables will disagree" warning, finally measured + +Carried forward as the sweep's one unresolved item: holographic_sdf.to_glsl and sdfemit.sdf_dialect both emit +a map() for the same tree, sdfemit's own header warns that TWO TABLES FOR ONE CONCEPT WILL DISAGREE and that +the disagreement will be a bug in one of them -- and only sdf_dialect had ever been run. "They agree" was a +narrative. The existing test compares DIALECT FIELDS, not arithmetic. + +THE BLOCKER WAS FALSE, which is the lesson. Judging GLSL looked like it needed a GL runtime this project does +not have -- I said so myself last session. But the GLSL these emitters produce is a tiny subset (vec3, +-*/, +abs/min/max/length/clamp/dot, and mat3), and C++ HAS OPERATOR OVERLOADING, so a ~40-line vec3/mat3 shim makes +the SAME TEXT compile and run under g++. Cost: one probe for the compiler. The bar stayed EXECUTED, the +standard the C dialect already set. GENERALISED: "we cannot test this without " deserves the same +five-lever treatment as any other wall -- the subset actually used is usually far smaller than the language. + +BUILT in holographic_sdfemit: validate_glsl (compile to_glsl's helpers+map() with a shim, run, compare to the +Python _eval), emitters_agree (runs BOTH paths and judges each), GLSL_AGREEMENT_TOL, plus 2 faculties and a +capability (5/5 phrasings top-1). The shim REFUSES what it cannot model (mat2/mat4/textures/iResolution) +rather than comparing something mis-modelled -- a validator that quietly gets semantics wrong is worse than +none. + +THE RESULT: THE TWO EMITTERS AGREE, and the residual is fully explained rather than merely small. + sphere / box / translated / union / smooth_union ~1e-7 + rotated box / compound (mat3 present) 3.7e-7 / 4.3e-7 + sdf_dialect c_f64 (same trees) 0.0 -- 6.7e-16 +TWO SOURCES, BOTH IDENTIFIED: (1) GLSL `float` is 32-BIT BY LANGUAGE DEFINITION, so a shader can never match +a float64 tree exactly -- bit-identity was the WRONG BAR and demanding it would have been asserting a wish +rather than the contract; (2) to_glsl formats literals to SIX SIGNIFICANT DIGITS -- cos(0.7) ships as +0.764842, itself 1.9e-7 off -- which is why a rotation is the worst case. GLSL_AGREEMENT_TOL = 1e-5 sits two +orders above the worst measured value and far below any geometrically meaningful distance, so a REAL +divergence still trips it. The C dialect keeps the exact bar because nothing stops it being exact: holding +the two sides to DIFFERENT bars is the honest choice, not a concession. +STATUS OF to_glsl, now sayable: a DISPLAY PROJECTION accurate to ~4e-7, not the authoritative geometry. That +sentence was unavailable before this ran. +EDIT-DISCIPLINE SLIP, recorded: the faculty insertion used `t[:i] + add + t[i:]` with `add` ALSO ending in the +anchor, which duplicated `def _selftest(` and broke the module at import. Caught immediately by +file_python_check; the repair script then failed too because it imported lecore at the top, which cannot +import a broken tree -- REPAIR SCRIPTS MUST USE PLAIN FILE I/O. Both re-learned the cheap way. +Battery 0/0/0; 65 tests green across sdf/sdfemit/routing/split/realtime; docs regenerated. + +## PYPI PUBLISH KEPT SKIPPING -- a false premise I wrote, with a real consequence + +Moose: something is making the PyPI publish skip. Traced without guessing, by reading the gate chain. + +package.yml's publish job is gated on `workflow_run.conclusion == 'success'` AND head_branch main/master. A +"Skipped" in the UI therefore means one of exactly two things, and BOTH are worth separating: + +1. EXPECTED NOISE, not a defect: package.yml triggers on EVERY completion of `tests`, including PULL REQUEST + runs, whose head_branch is the feature branch. Those runs can never publish and always render as Skipped. + Anyone scanning the Actions list sees a wall of them. This is by design and should not be "fixed". +2. THE REAL ONE: a red `tests` on main. The publish then skips CORRECTLY -- and stays skipped, because + nothing re-verifies main afterwards. + +ROOT CAUSE OF (2), AND IT IS MINE: the semantic-coverage heal commit carried a WHY-comment I wrote claiming it +"RE-TRIGGERS CI (no [skip ci])". THAT IS FALSE. A push authenticated with the default GITHUB_TOKEN DOES NOT +CREATE WORKFLOW RUNS -- GitHub's documented loop-breaker -- so the heal commit is invisible to `tests` whether +or not [skip ci] is present. My removal of [skip ci] was INERT, and the stated goal ("a main that heals itself +in the same push cycle") was never achieved. The consequence was not cosmetic: seed/index lockstep is +ASSERTED by the suite, so a stale seed makes `tests` fail on main; the heal fixes the artifact but cannot +re-run the suite; main's last conclusion stays FAILURE; and package.yml keeps skipping the publish run after +run. A wrong sentence in a comment became a silent release outage. + +FIX: after the heal pushes, DISPATCH `tests` explicitly -- workflow_dispatch IS honoured for GITHUB_TOKEN and +does create a run, which is the one trigger available. Added `actions: write` to the job (the permission the +dispatch needs) and a non-fatal `gh workflow run ci.yml --ref ` with GH_TOKEN in the step env; a +refreshed index is still worth having if the dispatch fails, and the weekly full run reaches the same place. +VERIFIED THE DISPATCH ACTUALLY LEADS TO A PUBLISH rather than assuming: on workflow_dispatch ci.yml runs +`full-suite` and SKIPS `pytest` (their `if`s are complementary), a skipped job does not fail a run, so a green +dispatch concludes SUCCESS with head_branch=main -- exactly what package.yml's gate wants. All five workflows +re-validated as YAML. + +LESSONS, both cheap to state and expensive to have missed: + * A CI comment asserting a PLATFORM BEHAVIOUR is a claim like any other and deserves the same standard as a + performance number. "This re-triggers CI" was never tested and was wrong. + * When a gate is DOWNSTREAM of a conclusion (workflow_run + conclusion == success), anything that leaves the + upstream red is not a test failure but a RELEASE failure. The blast radius of a red main is larger than + the test that is red. + * Also fixed a self-inflicted YAML slip: the `env:` block was patched INSIDE the run script's shell body, + which yaml caught immediately -- workflows get parsed after every edit, same discipline as + file_python_check for Python. + +## "137 CHANGED FILES WITH EMPTY DIFFS" -- measured: NOT our line endings, but now guarded + +Moose saw ~137 modified files whose diffs looked empty and suspected line-ending churn. MEASURED BEFORE +ANSWERING, because "probably line endings" is exactly the kind of plausible story that wastes a day: + + * every .py file in EVERY tree (delivery, both incoming branches, the pre-merge tree) is PURE LF: + CRLF=0, LF=1341, MIXED=0. No CRLF/LF flip was introduced by any edit in this arc. + * whitespace-only churn between trees: ZERO. Comparing each differing file with + `diff --strip-trailing-cr -B -b`, 46 differ vs the pre-merge tree and 54 vs the branch -- and NONE of + them collapses to whitespace. Every diff is real content. + * permission/mode-only diffs: ZERO. + * ranking the diffs by size shows no trivial ones -- the smallest are tens of real lines. + * the delivery ships ZERO text files containing CRLF. (83 files contain the bytes 0D 0A, all of them + PNG/npy/hsp binaries where that sequence occurs naturally in compressed data -- git treats them as + binary because they carry NUL early. The only non-obvious case, LICENSE, is genuinely text.) + * a FIRST-PASS SCRIPT SAID THE OPPOSITE -- "1339 files contain CR" -- because `grep -q $"\r"` in bash is + locale-translation syntax, not an escape, so it searched for a literal backslash-r and matched every + Python file containing "\r\n" IN A STRING. The number was garbage and was thrown out. Worth keeping: a + measurement that confirms the suspicion on the first try deserves MORE scrutiny, not less. + +SO WHERE DO THE PHANTOM DIFFS COME FROM? Not the file contents -- the INDEX. .gitattributes declares +`* text=auto`, so git stores text LF-normalised. Anything committed before that took effect (or committed +from a Windows checkout with core.autocrlf) sits in the index with CRLF, while the working tree is now LF. +Git then reports EVERY LINE of those files as changed and the rendered diff looks empty, because the content +IS identical. It is a one-time index/worktree mismatch, and the canonical fix is a renormalisation commit: + git ls-files --eol | grep -v "i/lf" # names exactly the files whose INDEX copy is not LF + git add --renormalize . # rewrite the index to match the declared policy + git commit -m "normalize line endings" # one commit, after which the phantom diffs are gone for good + +GUARD ADDED so this cannot drift back in from our side: test_no_text_file_ships_crlf walks every tracked +text file and fails with the offenders NAMED, plus test_gitattributes_declares_lf_normalisation, which pins +the policy the first test enforces (a guard for a setting nobody set is a lie). MUTATION-TESTED: a planted +CRLF file makes it fail and the message names that file. This is the same rule as the cross-burial matrix -- +when a class of problem reaches a human as "the tooling looks broken", promote the CHECK, not the discipline. + +## THE PHANTOM DIFFS, PART 2: not line endings at all -- the delivery was reverting CI-OWNED FILES + +The first pass proved our text is LF-only and found no whitespace churn, but the count barely moved (137 -> +128), so the first answer was INCOMPLETE. Widened the measurement -- and the earlier scan had a hole worth +naming: it globbed `*.py` ONLY, so .md/.yml/.json were never checked. Re-scanned every text type across all +four trees: still ZERO CRLF anywhere. Line endings are conclusively not the cause from our side. + +WHAT THE WIDER MEASUREMENT FOUND INSTEAD. Against the pre-merge tree the delivery touches 62 files (44 text +changed, 14 added, 4 removed -- and the 4 removed are .pytest_cache junk, which is gitignored, so nothing +real is lost). 62 is not 128. The gap is files whose live copy on main is written BY CI, not by us: + + VERSION package.yml bumps the patch digit EVERY release + lecore_data/routing/index_128d.npz semantic-coverage.yml rebuilds and commits it every push + tools/semantic/routing_seed.npz.xz same commit, the other half of the lockstep pair + REFERENCE / CAPABILITIES / capabilities.json / API_QUICKREF / FACULTY_MAP / DOC_MAP / PIPELINE_MAP / pipelines.json + docs.yml regenerates and commits them + +A source snapshot carries whatever those files were when it was cut, so applying it over a live main REVERTS +every one of them -- and they are exactly the files a human scrolls past without recognising a real change. +THE HARMFUL ONE IS VERSION: our snapshot said 0.2.0. Reverting it makes the next auto-bump collide with a +number already on PyPI, and PyPI REJECTS re-uploads of an existing version. That is a second, independent +cause of publishing trouble sitting behind the workflow_run gate fixed earlier -- and it would have been +invisible until the next release attempt. + +FIX (delivery-side, not repo-side): the archive now EXCLUDES the three files CI genuinely owns (VERSION and +the routing index + seed) so it cannot revert them, and ships DELIVERY_NOTES.md stating who owns what, what +breaks if each is overwritten, and the three commands that tell a human WHICH kind of empty-looking diff they +are looking at (`git diff --numstat` zero/zero rows = mode or binary; `git diff --summary` = mode changes; +`git ls-files --eol | grep -v i/lf` = index/worktree EOL mismatch). Generated docs stay IN the archive +deliberately -- a standalone extract must be complete, and the next push regenerates them harmlessly. +VERIFIED the trimmed archive still boots standalone: 2571 caps, find_capability works, 0 CRLF text files. + +LESSON: "which of these files does something OTHER than this snapshot own?" is a question a delivery should +answer explicitly. An artifact that is regenerated by CI is not source, and shipping it as if it were makes +every delivery look like a large uninterpretable change -- and, in VERSION's case, breaks a release. +Also: when a fix moves the number from 137 to 128, that is not confirmation, it is a SECOND CAUSE announcing +itself. The first explanation was true and insufficient; both had to be found. + +## CI RED AFTER THE THIRD MERGE: the split REVERTED shipped work, and my merge filter dropped fixes + +Eleven failures across seven suites. ONE ROOT CAUSE PAIR, both worth naming because both were self-inflicted +and both are structural, not sloppiness: + +(A) THE CATALOG SPLIT REBUILT holographic_catalog.py FROM AN OLDER COPY. The six parts were extracted +correctly, but the surrounding module came back without work that had shipped in it. Silently reverted: + * `_strip_filler` + `_FILLER_PREFIXES` + BOTH `q_stripped` call sites -- the whole filler-stripping fix, + which two modules and two test files import. The function was gone AND the exact-alias comparison that + used it. Restored all three pieces. + * `route_or_abstain`'s EMPIRICAL p -- the 3-tuple null cache and the counted (not normal-approximated) p. + The split's copy returned the older 2-tuple version with no `p` key at all, breaking six ladder tests. + Ported the 83-line body back from the pre-split tree. +(B) MY ADDITION-ONLY MERGE FILTER DROPPED FIXES EXPRESSED AS MODIFICATIONS. Filtering the branch's diff to +addition-only hunks was the right call for a wrong-base merge (it stopped age being read as deletion), but a +FIX is usually a deletion plus an addition, so every fix in a modified hunk was silently skipped. Caught: +`compare_image_files` still hard-importing PIL -- the branch shipped BOTH the fix and the test pinning it, my +filter took the test and dropped the fix. Ported their PIL-free implementation. + -> SWEPT FOR MORE rather than assuming that was the only one: hashed every callable on UnifiedMind AND + every catalog function, pre-split vs now, at METHOD granularity. 1589 vs 1619 callables, ZERO lost, 5 + changed -- four are the fixes above plus my crossover_report rename, and the fifth (render_scene_document + gaining view=/affine=) is the branch's own new work correctly merged. The class is closed, measured. + +CROSS-BURIAL, THIRD WAVE. ~57 new capabilities re-ranked older ones out of their own probes: the catalog +selftest lost two ("represent a density volume over space", "my placed light has speckle noise") and 25 bare +method-names fell out of their own top-15. Fixed additively -- aliases in the parts, and the 25 through the +existing _METHOD_ALIASES map (the documented D1 mechanism) rather than 25 ad-hoc edits. + +SIX BYTE-IDENTICAL `_selftest` BODIES across the catalog parts tripped the duplication budget. Unified into +holographic_catalog.check_catalog_part, mirroring the precedent holographic.unified.check_part already set. +The budget says MAY SHRINK, MUST NEVER GROW -- so the fix is one home, not a budget line. + +TWO TESTS PINNED SNAPSHOTS OF THINGS THE SYSTEM IS ALLOWED TO CHANGE, and both failed BECAUSE THE SYSTEM GOT +BETTER. Rewritten to assert the relationship instead: + * the z-floor calibration test demanded p > 0.05 for "smooth a bumpy mesh". Adding the alias map moved that + query from z=1.10/p=0.18 to z=4.20/p=0.015 -- the router improved. The real claim is that z and p are + DECOUPLED, so it now asserts a barely-clearing query (z=0.68, p=0.40) sits >5x above a strong one, which + survives catalog growth. + * the 2-bit quantization test demanded flip_rate == 0.0. That is a statement about INDEX DENSITY, which CI + regenerates: 509 rows flips nothing, 578 rows flips 1 in 150 at the most aggressive width. A denser index + having tighter margins is "margin governs, not bit width" WORKING. Now: 8/4-bit decision-exact, 2-bit + bounded at 2/150, AND the margin separation from ambiguous queries re-checked at the same width -- so the + tolerance is a statement about margins, not a licence for the claim to rot. +LESSON: a test that fails when the system IMPROVES is measuring the wrong thing. Pin the relationship the +claim is about, never a number the system is allowed to move. +All seven gates green; 90 tests across the nine affected suites pass; both repaired module selftests green. + +## J-3D-26 CLOSED: a TRIPWIRE test fired because the thing it guarded got fixed + +CI showed one F early in the fast suite. Reproduced locally by running the RANKING-SENSITIVE tests first +rather than bisecting 629 files blind -- the reasoning being that this session's fixes (restoring q_stripped, +adding 25 _METHOD_ALIASES entries, pinning Field and the light probe) all move GLOBAL ranking, so a +discoverability test was the likely casualty. It was, in one shot. + +WHAT IT WAS, AND IT IS A GOOD OUTCOME: test_field_query_regression_is_recorded_not_hidden asserted the BROKEN +state -- that "represent a density volume over space" does NOT surface Field. It was written as a deliberate +tripwire when the previous branch found holographic_catalog._selftest() failing on that probe: rather than +relax the selftest (which would file a real discoverability regression as noise), they pinned the breakage and +left instructions in the assertion message -- "the Field ranking appears FIXED -- delete this test, restore +the assertion in _selftest(), and close J-3D-26". Fixing the ranking earlier this session tripped it exactly +as designed. The test worked. + +RESOLVED BY FOLLOWING ITS OWN INSTRUCTION, with one improvement: rather than DELETE the slot, it now holds +the mirror-image pin -- Field MUST be in the top-3 for that phrase -- with the reason the fix was additive +(Field carried only single-word aliases: 'field', 'grid', 'volume'; single words lose to descriptively-titled +siblings as the catalog grows, so the PHRASE a user types was added, nothing was demoted or relaxed). Keeping +the slot matters because of the tripwire's OWN bigger finding: this module's _selftest is only reached by +`python -m`, which is how the original rot sat green -- so the suite pins it too now. + +VERIFIED THE FIX DID NOT BURY ANYTHING ELSE, since that is this session's recurring class: ran every test file +that calls find_capability / find_scored / route_or_abstain -- 395 passed, 92 skipped, zero failures -- plus +the module-selftest walker (test_all_selftests) green, which is the audit that would catch another rotting +selftest. All seven gates clean; docs regenerated. + +LESSON WORTH KEEPING: a test asserting a KNOWN-BROKEN state is a legitimate and underused artifact. It cannot +rot silently (fixing the bug fails the test), it carries the fix instructions to whoever trips it, and it +prevents a real regression being quietly downgraded to a relaxed assertion. The failure mode it guards +against -- "just loosen the selftest" -- is exactly what would have happened otherwise. + +## PART SIZE GATE TRIPPED BY MY OWN PORT -- p09 rebalanced; two parts now near the cap + +Two failures reported. ONE WAS STALE, ONE WAS REAL, and separating them mattered: + +STALE: test_field_query_regression_is_recorded_not_hidden failed again -- but that test NO LONGER EXISTS in +this tree (replaced last session by test_the_field_query_ranking_stays_fixed, and verified absent from the +delivered archive). That CI run predates applying the delivery. Nothing to fix; recorded so the next reader +does not go looking for a bug that was already closed. + +REAL, AND MINE: holographic_unified_p09 hit 2007 lines against a 2000 cap. Cause is traceable to this +session: recovering the branch's scene/asset faculties after the addition-only filter dropped them, I ported +SEVEN methods into p09 (sky_model, load_hdr, load_image, fetch_asset, render_animation, describe_to_scene, +refine_scene) plus the PIL-free compare_image_files -- all correct work, all landed in one part because that +is where the branch had them, and the part was already the largest. +FIXED BY THEME, NOT BY THE FIRST CUT THAT FITS: moved fetch_asset / load_hdr / load_image to p01_READ, which +is literally the part about input -- an asset fetch and two image loads are reads. sky_model, render_animation, +describe_to_scene and refine_scene stayed in p09 with the scene/render work they belong to. p09 2007 -> 1952, +p01 1423 -> 1479, all 1571 faculties still reachable (checked through the mind, not by reading the diff), +split gate green, 85 tests across the affected suites pass. +DID NOT raise PART_MAX_LOC. The budget is the whole point of the split; raising it to fit my own port would +have been the exact move the unified split existed to prevent. + +HEADROOM WARNING, worth acting on before the next feature lands: p09 is at 1952 and p03_build_predictor at +1941 -- both within ~50 lines of the cap, i.e. ONE faculty from tripping the gate again. The split's own test +message says "split it again"; the cheap version is a further rebalance (p09's navigation/cost-field group and +p03's predictor group are each coherent enough to become their own part). Flagged rather than done, because a +speculative refactor of the faculty surface is not something to slip into a bugfix pass. + +## SAME TWO FAILURES, IDENTICAL LINE NUMBERS: the delivery is not reaching CI + +Third report of the same two failures, byte-identical to the previous one (same test name, same "2007"). +Checked the DELIVERED ARCHIVE directly rather than re-fixing what was already fixed: it contains +test_the_field_query_ranking_stays_fixed at line 200 (the tripwire is absent) and p09 at 1952 lines. CI +reports the tripwire and 2007. THE FIXES ARE IN THE ARCHIVE AND NOT IN THE TREE CI RUNS -- so the problem is +the APPLY STEP, not the work. Most likely: the archive was not applied to the branch CI builds, or a +phantom-diff cleanup (`git checkout .` / `git restore .` against the ~128 line-ending diffs) discarded real +edits along with the noise, which is exactly the trap that class of churn sets. + +SHIPPED A DIFFERENT APPLY MECHANISM: tools/apply_ci_fixes.py, idempotent, finds its targets BY NAME. +WHY NOT A PATCH: a unified diff needs exact surrounding context, and this tree has drifted (a delivery may +have been applied in whole, in part, or not at all). A reconstruction of CI's state came out 11 lines off my +own tree, which is precisely the drift that makes `git apply` fail. A script that no-ops when the work is +already done applies correctly from EITHER state. + +THE SCRIPT'S OWN BUG, CAUGHT BY TESTING IT ON THE STATE IT REPAIRS. First run against the reconstructed +broken tree aborted: "p01 has no module-level _selftest". The cut helper bounded a method by the next +` def ` only -- so when the method is the LAST in its class it ran to EOF and swallowed the module-level +_selftest and the __main__ guard. My reconstruction had used the same logic and corrupted its own p01. +Fixed to bound by the next sibling OR the first line back at column 0. VERIFIED PROPERLY AFTERWARDS: rebuilt +a faithful broken tree (p09 2008 lines, both tests failing), ran the script, both tests pass, second run +no-ops, 1571 faculties intact and the moved three still reachable. +LESSON: a fix script tested only against an ALREADY-FIXED tree proves nothing -- it must be run against a +reconstruction of the state it exists to repair. The no-op path is the easy half; the repair path is where +the bug was. + +## CI GATE AUDIT: two checks were enforcing FILING, not correctness -- demoted to reports + +Moose: the pipeline should check for ERRORS, not character counts and file counts. Audited every gate against +one question -- WHAT BREAKS IF THIS FAILS? -- rather than whether it looked tidy. + +KEPT GATING (each names something genuinely BROKEN, and each has caught a real defect on record): + audit_imports an import that does not resolve + wiring_report a module nothing can reach (caught the catalog parts' invisible import style) + catalog_gaps a capability with no home or no runnable example + skill_lint CRITICAL/BROKEN/inert a method an agent cannot call, an example that does not resolve, + an alias that reaches nothing + tag_lint io tags that LIE about what a converter consumes/produces + test_all_selftests caught the rotting catalog selftest this very session + part max LOC maps to a HARD constraint: a file past the ~1 MB agent-read cap cannot be read in one + pass, so the engine actually loses a capability. The number is a proxy; the loss is real. + +DEMOTED TO REPORTS (they were failing builds over filing decisions): + * skill_lint's 600-char does-field budget. Its OWN section comment already called it "a WARNING tier, not + a hard gate" -- but the regression count was added to `total`, which is the exit code, so a 620-character + description failed the build. Behaviour contradicted documented intent. MEASURED COST: six separate + prose-trimming rounds in one session, every one of them rewording a correct sentence to satisfy an + arithmetic threshold. CAUGHT-DEFECT COUNT: zero. An over-long entry is still correct, still discoverable, + still invocable. Now reported, not gated. + * structure_audit's misc/ file-count budget. 151 modules instead of 150 breaks nothing -- every one of them + imports, is wired, is discoverable, is tested. It blocked a merge until a correct module was relocated: + a filing decision enforced as an error. Still REPORTED (a swelling misc/ is a real smell and the nudge to + a real family is a good one), no longer fatal. Mutation-tested: an over-budget misc/ now exits 0 with a + NOTE. The giant-module budget beside it STAYS gating, because that one maps to the agent-read cap. + +NOT CHANGED, and why: the up-to-date checks on generated docs are drift gates, and stale generated docs LIE +to whoever reads them -- that is an error, not bookkeeping. Same for the SERVICE.md endpoint gate: an +undocumented endpoint is an agent-facing gap. + +THE REAL BLOAT IS ELSEWHERE, and it is worth a decision rather than a unilateral change: 3.4 MB of generated +docs are regenerated AND COMMITTED on every push -- REFERENCE.md 1.86 MB, capabilities.json 740 KB, +CAPABILITIES.md 509 KB, FACULTY_MAP 195 KB. The CONTENT is not padding (REFERENCE is aggregated module +docstrings, ~42 lines per module across 578 modules), so there is nothing to trim inside it; the cost is that +every push rewrites megabytes of derived files, which is also what makes a delivery look like a huge +uninterpretable diff. RECOMMENDATION, for Moose to call: keep committing capabilities.json (it is the +machine-readable contract other things consume and the drift gate protects it) and publish REFERENCE.md as a +CI ARTIFACT instead of a committed file. That removes ~1.9 MB of per-push churn without losing anything a +reader cannot regenerate. Not done unilaterally -- it changes what the repo publishes. + +PRINCIPLE, recorded: a gate should fail only when something is BROKEN. "Would a user or an agent be unable to +do something?" is the test. If the honest answer is "no, but it is untidy", it is a report. + +## "IS REFERENCE.md SLOPPED TOGETHER IN NO PARTICULAR ORDER?" -- measured: NO, but the TEST could not tell + +Moose's hypothesis: the generated docs churn because they are assembled non-deterministically, so a rerun +reshuffles megabytes with no real change. TESTED RATHER THAN ARGUED -- regenerate, compare bytes: + REFERENCE.md / CAPABILITIES.md / capabilities.json: IDENTICAL on a second run, and IDENTICAL AGAIN under + PYTHONHASHSEED=random. The generators are pure functions of the source. Hypothesis refuted. +ALSO CORRECTED A CLAIM OF MY OWN from the previous entry: I wrote that 3.4 MB is "regenerated AND COMMITTED +on every push". The regeneration happens every push; the COMMIT is guarded by `git diff --quiet $DOCS`, so +derived files only land when they genuinely changed. The churn is real work, not noise. Imprecise the first +time, corrected here. + +BUT THE QUESTION EXPOSED TWO REAL HOLES, both in the machinery that was supposed to guarantee the answer: + 1. docs.yml -- THE ONE WORKFLOW THAT WRITES GENERATED DOCS -- did not pin PYTHONHASHSEED. ci.yml, + semantic-coverage.yml and wgsl.yml all do. Harmless today because the generators are deterministic + anyway, but it is precisely where a hash-order dependency would do its damage silently: an unpinned + generator iterating a set rewrites megabytes with no content change, and the commit-if-changed guard + faithfully commits the churn. Pinned. + 2. test_gated_generators_are_deterministic ran the generator TWICE IN THE SAME ENVIRONMENT, so both passes + inherited ONE hash seed -- and its own docstring claimed it caught "dict-order" bugs. It could not: an + order-dependent generator emits the SAME bytes twice under a fixed seed and passes. Now runs the two + passes under DIFFERENT seeds (0 and 1618033), which is what actually exercises the claim. Verified the + seeds bite: the same 5-element set iterates as alpha,beta,gamma,delta,epsilon vs + beta,delta,epsilon,alpha,gamma across them. + +LESSON, and it is the same shape as the CI-comment-asserting-platform-behaviour one: A TEST THAT CANNOT FAIL +FOR THE REASON ITS DOCSTRING NAMES IS A FALSE GREEN. This one had been passing for a while while being +structurally incapable of catching its stated target. Checking the CHECK is worth doing whenever a question +like "is this actually deterministic?" gets asked -- the honest answer came from measurement, and the +measurement is now automated instead of being a thing I did once by hand. diff --git a/docs/PIPELINE_MAP.md b/docs/PIPELINE_MAP.md index deefe61..eff0198 100644 --- a/docs/PIPELINE_MAP.md +++ b/docs/PIPELINE_MAP.md @@ -2,7 +2,7 @@ *The workflow graph, auto-derived by `pipelinemap.py` from the catalog's `consumes`/`produces` tags.
