Subject: [PATCH 1/9] chore: gitignore ephemeral runtime dirs, add research doc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ignore .claude/sessions/, .kata/verification-evidence/, and
eval-transcripts/ — these are generated at runtime and should
not be tracked.

+# Research: Dynamic Task Creation Generalization
+
+## Questions Explored
+- How does verify mode's dynamic task creation work?
+- Which other modes would benefit from the same pattern?
+- What changes are needed to generalize it?
+
+## Current State
+
+### Task creation mechanisms today
+
+| Mode | Task Creation | Method |
+|------|--------------|--------|
+| planning | 16 static tasks | Template phases → `buildPhaseTasks()` at enter time |
+| implementation | Static + spec-driven | Template + `buildSpecTasks()` with subphase patterns at enter time |
+| task | 6 static tasks | Template phases → `buildPhaseTasks()` at enter time |
+| verify | Static + **dynamic** | Template + `TaskCreate` at runtime in container phase |
+| research | **None** | Has phases/steps but no tasks created |
+| debug | **None** | Has phases/steps but no tasks created |
+| freeform | **None** | No phases at all |
+
+### Verify mode's pattern (the one that works)
+
+Verify mode uses a discover-then-expand pattern:
+
+```
+P0: Setup (static tasks)
+    → Discovers VP steps from spec, plan file, or git diff
+
+P1: Execute (container: true)
+    → expand-vp-steps calls TaskCreate per discovered VP step
+    → Each VP step becomes a trackable, completable task
+
+P2+: Operate on those dynamic tasks (fix loop, evidence)
+```
+
+Key design elements:
+- P1 is marked `container: true` in the template YAML
+- The template instruction explicitly tells the agent to call `TaskCreate`
+- A special exception overrides the "no TaskCreate" rule for verify mode only
+- Tasks are created ALL at once before execution begins
+- Each task is independently trackable (pass/fail per VP step)
+
+### The current gate
+
+Verify has a hardcoded exception:
+
+> "Verify mode is the **only mode** that uses `TaskCreate`. This overrides the standard `task_rules`..."
+
+This is the only thing preventing other modes from using the same pattern.
+
+## Key Finding: The Pattern is Template-Driven, Not Mode-Driven
+
+Verify's dynamic task creation isn't special infrastructure — it's just a template instruction that says "call `TaskCreate` here." The `container: true` phase marker already exists in the schema. The only blocker is the policy gate that restricts `TaskCreate` to verify mode.
+
+**Proposed change:** Make the `TaskCreate` exception phase-driven rather than mode-driven. Any phase with `container: true` allows `TaskCreate` within that phase.
+
+## Candidate Modes for Dynamic Task Creation
+
+### Planning Mode — strongest candidate
+
+**Current problem:** P2 (Spec Writing) has 3 static tasks regardless of feature complexity. A simple config change and a complex multi-service feature get the same task structure.
+
+**Dynamic pattern:**
+```
+P0: Research (static — 2 tasks)
+P1: Interview (static — 5 tasks)
+    → Discovers: behaviors, integration points, test scenarios
+
+P2: Spec Writing (container: true)
+    → After P1 requirements approval, expand per behavior:
+      - "Write B1: auth flow"
+      - "Write B2: token refresh"
+      - "Write B3: session management"
+    → Each behavior section independently trackable
+
+P3: Review Gate (static — 3 tasks)
+P4: Finalize (static — 3 tasks)
+```
+
+**Benefits:**
+- Progress tracking per behavior (not just "spec writing in progress")
+- Natural parallelism — behaviors can be written by parallel agents
+- Review can reference specific behavior tasks
+- Scales with feature complexity (2 behaviors = 2 tasks, 10 = 10)
+
+**Trade-off:** Currently a single agent writes the whole spec in one shot, which preserves cross-behavior coherence. Per-behavior tasks would need a "coherence pass" afterward, or a shared context doc that each behavior writer reads.
+
+### Debug Mode — strong candidate
+
+**Current problem:** No tasks at all. Progress is invisible.
+
+**Dynamic pattern:**
+```
+P0: Reproduce (static — 2 tasks)
+    → Discovers: symptoms, affected code paths
+
+P1: Hypotheses (container: true)
+    → After reproduction, expand per hypothesis:
+      - "H1: Race condition in session cleanup"
+      - "H2: Stale cache after config reload"
+      - "H3: Off-by-one in pagination"
+    → Each hypothesis independently testable/dismissable
+
+P2: Fix (static — depends on which hypothesis confirmed)
+P3: Verify fix (static — 2 tasks)
+```
+
+**Benefits:**
+- Hypotheses are tracked (tested/confirmed/dismissed)
+- Stop conditions can check "at least one hypothesis confirmed"
+- Natural debugging workflow — you don't know the hypotheses upfront
+
+### Research Mode — moderate candidate
+
+**Dynamic pattern:**
+```
+P0: Initial scan (static — 2 tasks)
+    → Discovers: research threads to investigate
+
+P1: Deep dive (container: true)
+    → After initial scan, expand per thread:
+      - "Investigate logging architecture"
+      - "Map auth middleware chain"
+      - "Compare caching strategies"
+    → Each thread independently explorable
+
+P2: Synthesize (static — 2 tasks)
+P3: Document (static — 2 tasks)
+```
+
+**Benefits:**
+- Research coverage tracked per thread
+- Natural parallelism for independent threads
+- Output doc can reference which threads were explored
+
+**Trade-off:** Research is intentionally exploratory. Too much structure might constrain discovery. Could make the container phase optional — only expand if the agent identifies discrete threads.
+
+### Task Mode — poor candidate
+
+Already lightweight (6 tasks). The whole point is "small change, minimal ceremony." Dynamic expansion would fight the mode's purpose.
+
+### Freeform — not a candidate
+
+Intentionally unstructured. No phases at all.
+
+## Implementation Path
+
+### Step 1: Make `TaskCreate` gate phase-driven
+
+Change the `TaskCreate` restriction from "mode === verify" to "current phase has `container: true`". This is likely in the mode-gate hook or task rules documentation.
+
+**Files to check:**
+- `src/commands/hook.ts` — mode-gate hook logic
+- Template task_rules section — documentation that agents read
+- Any PreToolUse hook that blocks `TaskCreate`
+
+### Step 2: Update templates that want dynamic creation
+
+Add `container: true` to the relevant phase and write the expand instruction. No TypeScript changes needed — this is purely template content.
+
+### Step 3: Wire stop conditions
+
+Modes using dynamic tasks should add `tasks_complete` to their `stop_conditions` in `modes.yaml` so the stop hook enforces completion.
+
+### Incremental rollout
+
+1. **First:** Just lift the verify-only restriction (step 1). No template changes yet.
+2. **Then:** Update debug template to use container phase for hypotheses — simplest template to modify, low risk.
+3. **Then:** Planning P2 — higher impact but needs the coherence-pass design decision.
+4. **Last:** Research — only if the pattern proves valuable in debug/planning.
+
+## Open Questions
+
+- **Planning coherence:** If behaviors are written as separate tasks, how do you ensure cross-behavior consistency? Options: shared context doc, coherence review pass, or keep single-agent-writes-all but track per-behavior review tasks instead.
+- **Task naming convention:** Verify uses `VP{N}: {title}`. Should other modes follow a similar pattern? (`H{N}:` for hypotheses, `B{N}:` for behaviors, `R{N}:` for research threads?)
+- **Container phase nesting:** Can a mode have multiple container phases? (e.g., planning could have container phases in both P2 and P3 for per-behavior writing AND per-behavior review)
+
+## Next Steps
+
+- Create GitHub issue for this feature
+- Start with step 1 (lift verify-only gate) as a small task
+- Design debug template update as proof of concept

Subject: [PATCH 2/9] feat: session-scoped file tracking via PostToolUse hooks
 (#62)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add PostToolUse hook that tracks which files each session modifies via
an append-only edits.jsonl log. Scope committed/feature_tests_added stop
conditions and task-evidence warnings to only consider session-owned files.

Key changes:
- New src/tracking/edits-log.ts module (appendEdit, readEditsSet, baseline)
- handlePostToolUse in hook.ts for Edit/Write/NotebookEdit/Bash tracking
- Bash mutation detection via safe-list → suspicious-regex → git-status diff
- Baseline snapshot on kata enter to exclude pre-existing dirty files
- Session-scoped checkGlobalConditions and checkFeatureTestsAdded
- Advisory warning for out-of-scope dirty files
- PostToolUse hook registration in settings.json via setup.ts

Subject: [PATCH 3/9] fix(test): migrate test paths from .claude/ to .kata/
 layout

Fix 17 pre-existing test failures caused by tests writing session state
and config to .claude/ paths while runtime code expects .kata/ paths.
Also fix schema validation for agent expansion and add missing stage
fields to stop-hook-test template.

From 193df9bed54131300416ef01978bafc3087cfd6e Mon Sep 17 00:00:00 2001
From: codevibesmatter <ben@codevibesmatter.com>
Date: Fri, 17 Apr 2026 13:24:20 -0400
Subject: [PATCH 4/9] fix(test): reset process.exitCode to 0 in tests (bun
 compat)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bun does not honor `process.exitCode = undefined` — once set to 1, it
stays latched. Use `process.exitCode = 0` instead. Also fix missing
exitCode destructuring in enter.test.ts rejects-unknown-mode test.

Subject: [PATCH 5/9] chore: update settings.json to consolidated PreToolUse +
 PostToolUse hooks

Replaces legacy mode-gate/task-deps/task-evidence entries with single
pre-tool-use handler. Adds PostToolUse hook for session file tracking.

Subject: [PATCH 7/9] fix: feature_tests_added graceful fallback when session
 edits don't cover test files

When session-scoped filtering produces an empty test file set (e.g.,
tests were written by agents before PostToolUse was registered), fall
back to the unfiltered list rather than failing the check.

`git status --porcelain` emits a leading space for worktree-only modifications
(index untouched), e.g. " M README.md". Four call sites used `.trim()` on the
full output, which stripped that leading space from the first line. Combined
with `parseGitStatusPaths`' `line.slice(3)`, this corrupted the first character
of the first dirty file's path — e.g. baseline captured "EADME.md" instead of
"README.md".

Fix: replace `.trim()` with `.replace(/\n+$/, '')` at all four sites (baseline
capture, scoped committed check, task-evidence pre-check, Bash pre/post
snapshots). This strips trailing newlines from execSync output without eating
the leading space of the first porcelain line.

Add two regression tests documenting worktree-only modification/deletion
status lines so callers' expected input shape is guarded.

Discovered during verify-mode e2e of PR #63 against issue #62.

Review of 0c687d7 found two concrete gaps:

1. **Missed call site**: handleTaskEvidence (src/commands/hook.ts:409) still
   used .trim() on porcelain output. While this site only uses the count
   (not parseGitStatusPaths), leaving it inconsistent invites the same bug to
   resurface if paths are later parsed. Fixed for consistency.

2. **Weak regression test**: the prior commit's tests only exercised the leaf
   parseGitStatusPaths helper, which was always correct — the bug was in the
   caller's .trim() corrupting input. Reintroducing .trim() at any fix site
   would not fail the prior tests. Added a real integration test that builds a
   git repo, makes a worktree-only modification (emitting " M README.md"),
   runs kata enter, and asserts baseline.json records "README.md" — verified
   to fail with the old .trim() and pass with the fix.
