33f4797ceb FN-126: fix inert sync-lane validation
Prevent inert synchronization lanes from bypassing merge-gate validation while preserving task-lane cache and archive lifecycle behavior.

- Reject sync-resolved lane conversions in the static validator.
- Preserve task-lane cache emissions and active-session cleanup across task mutations and archival.
- Add regression coverage, baseline updates, documentation, and a release changeset.

c05d44d44a fix(engine): bound planning retries and cap the planning turn
Three changes to the triage planning path.

1. Unclassified planning failures are bounded. specifyTask's catch-all branch —
the one reached by every error the classifiers above do not recognize — restored
the card's claimable status and wrote nothing else: no counter, no
nextRecoveryAt, no park. Triage rediscovery re-admitted the card on the very next
poll, and replaceActiveTaskWorkflowContinuation replaced the terminal work item
with a fresh one carrying no attempt count, so nothing recorded that the task had
already failed N times. It now consumes the same recoveryRetryCount/nextRecoveryAt
budget the transient branch uses (MAX_RECOVERY_RETRIES = 3, 60s/120s/300s jittered
backoff) and parks status:"failed" with a PLANNING_FAILED_EXHAUSTED: error once
spent — status:"failed" is what suppresses rediscovery. Classifying one error
string fixes one symptom; this budget is what makes the NEXT unrecognized error
fail safely instead of looping for a day.

2. The planning turn has a ceiling. Fusion set no timeout on it at all:
workflowStepTimeoutMs covers pre-merge workflow steps only, and the provider SDK's
300s APIConnectionTimeoutError caps time-to-first-byte and is cleared once headers
arrive, after which the stream is uncapped. configureHttpDispatcher, which would
install undici idle timeouts, is only called from pi's CLI entrypoints and never
in the in-process engine. Observed consequence: single attempts ran to 126 minutes,
with failed-attempt durations spread smoothly from 1 to 126 min and no clustering —
the signature of nothing enforcing a bound. New workflow-native planningTimeoutMs
(default 90 min) aborts the session; the failure consumes one bounded attempt.

The default is deliberately generous rather than tight. Successful planning work
items measured over 7 days ran p50 12.7 / p90 39.5 / p99 105.7 minutes, so a
tighter bound would abort legitimate plans and pay for the restart — the churn
this work exists to remove. It bounds hung turns, not slow ones.

3. [event:task:moved] executor tracing dropped from log to debug. It fires on
every dispatch, rebound, requeue, archive and self-healing move across every task,
which made it the loudest line in engine output and buried operator-actionable
events. No test pins the level; the information remains at debug.

Also fixes a test break shipped in 963dba6f80: the review blocking-severity
settings landed inside BUILTIN_REVIEW_REVISION_SETTINGS, whose contents
builtin-workflow-settings-triage.test.ts asserts exactly.

1cf86baa1c refactor: package code organization wave 18 (executor pure peels) (#3317)
## Summary

Wave 18 continues the package code-organization program after wave 17
domain folders (U4 Slice A from
`docs/plans/2026-07-14-001-refactor-package-code-organization-plan.md`).

### What changed
Peel **pure, behavior-preserving** helpers out of
`packages/engine/src/executor.ts` into domain modules under
`packages/engine/src/executor/`, with **stable re-exports** from
`executor.ts` so deep imports and `vi.mock("../executor.js")` keep
working.

| New module | Symbols |
|------------|---------|
| `executor/task-done-refusal.ts` | `evaluateTaskDoneRefusal`,
`determineRevisionResetStart`, skip-bypass refusal helper |
| `executor/workflow-feedback-paths.ts` |
`extractReferencedPathsFromWorkflowFeedback`,
`isAlwaysAllowedScopeLeakPath`, `workflowPathMatchesDeclaredScope` |
| `executor/workflow-step-verdict.ts` |
`FUSION_WORKFLOW_STEP_CONVENTIONS_PREAMBLE`, `parseWorkflowStepVerdict`
/ `parseWorkflowStepOutput`, step outcome types |
| `executor/await-input-parse.ts` | `parseAwaitInputSentinel`,
`parseAwaitInputQuestionToolCall` |
| `executor/no-commit-eligibility.ts` | `getNoCommitEligibilityReason`
(+ prompt heuristics) |

`executor.ts` live LOC ~**22817 → ~22427** (first pure-peel batch; more
peels needed to approach the 2k cap).

### Shims
- `old path` `executor.ts` public exports → `new path` `executor/*.ts` →
delete-when consumer deep-imports are re-pointed (not this PR)

### Test plan
- [x] `@fusion/engine` typecheck
- [x] Oracle: task-done refusal, skip-bypass, workflow malformed
verdict, scope-leak allowlist, executor-step-session, executor-prompt
- [x] `vitest --project=engine-core` (merge-gate curated suite)
- [ ] CI merge gate

**Stack:** wave17 (merged) → **this PR**
