Summary

Closes #441 — static guard-test for the workorder rule that session/run/task/chain/delegate/queue keyed Map/Set/WeakMap holding future/process-needed state needs an explicit safe-volatile justification or a substrate path. Until now: code-review-only. Now: substrate-canon enforced statically.

What it does

Scans the §4 continuation prod surface (per docs/test-trap-walk/codewalk-file-list.txt) for new Map|Set|WeakMap. Every occurrence must appear in an in-test ALLOWLIST array with five required fields:

  • owner — original author / current substrate owner
  • purpose — what the structure tracks
  • classificationsafe-volatile | load-bearing | ephemeral
  • restartContract — explicit description of restart behavior
  • justification — why this is safe-volatile (or why a load-bearing TODO is acceptable as interim state)

What it catches

  • New unallowlisted new Map<sessionKey, …> in any §4 prod file → fails with canonical Found N new \new Map|Set|WeakMap` occurrence(s) in §4 continuation surface that are NOT in the volatile-Map allowlist` message + remediation guidance
  • Stale allowlist entries (file/line no longer matches a prod occurrence) → fails with stale-entry message; prevents silent allowlist widening when prod code is deleted/moved

Initial allowlist (8 entries, 5 files at canonical2 cf7830ffb3702bf7d826d70838893e2e41709f12)

File Line Symbol Classification
request-compaction-tool.ts 48 pendingCompactionSessions safe-volatile
continuation/context-pressure.ts 44 lastFiredBand safe-volatile
continuation/delegate-dispatch.ts 33 hedgeTimers safe-volatile
continuation/delegate-store.ts 341 delayedReservations safe-volatile
continuation/state.ts 14 continuationTimerHandles safe-volatile
continuation/state.ts 17 continuationTimerRefs safe-volatile
continuation/state.ts 72 inline new Set([handle]) initializer ephemeral
reply/post-compaction-delegate-dispatch.ts 504 entryIds (function-local) ephemeral

All eight have explicit comment-block or RFC justifications already in source; the allowlist surfaces them as testable canon.

Load-bearing verification

# 1. Baseline: 1/1 pass on cfa27eee834
$ vitest run src/auto-reply/continuation/volatile-map-allowlist.test.ts
✓ 1/1 PASS (5ms)

# 2. Sabotage: append `const sabotageMap = new Map<string, string>();` to state.ts
$ vitest run src/auto-reply/continuation/volatile-map-allowlist.test.ts
× 1/1 FAIL — "Found 1 new \`new Map|Set|WeakMap\` occurrence(s) … NOT in the volatile-Map allowlist"

# 3. Restore: 1/1 pass
$ vitest run src/auto-reply/continuation/volatile-map-allowlist.test.ts
✓ 1/1 PASS

Companion test-trap surface

Third leg of the test-trap-walk's substrate-canon enforcement on the continuation surface:

Encoding-shape ⊕ API-surface ⊕ substrate-shape = three orthogonal regression-classes; no overlap.

… Maps

Static guard-test scanning the §4 continuation surface for `new Map` /
`new Set` / `new WeakMap` occurrences. Every prod occurrence MUST appear
in an allowlist with five required fields:

  - owner          : original author / current substrate owner
  - purpose        : what the structure tracks
  - classification : safe-volatile | load-bearing | ephemeral
  - restartContract: explicit description of restart behavior
  - justification  : why safe-volatile (or why load-bearing TODO is OK)

Adding a new `new Map<sessionKey, …>` without an allowlist entry fails
the test by construction. Stale allowlist entries (file/line no longer
matches a prod occurrence) also fail — prevents silent allowlist widening
when prod code is deleted/moved.

Closes #368-class enforcement gap: workorder rule for session/run/task/
chain/delegate/queue keyed Map/Set/WeakMap holding future/process-needed
state was code-review-only; now substrate-canon enforced statically.

Companion to:
  - PR #462 (#438): mode-only PendingContinuationDelegate trap (encoding-shape)
  - PR #463 (#446): continue_delegate descriptor closed-set trap (API-surface)

This is the third leg — substrate-shape enforcement over runtime state.

Initial allowlist captures 8 occurrences across 5 §4 prod files at
canonical2 `cf7830ffb3702bf7d826d70838893e2e41709f12`:
  - request-compaction-tool.ts:48 (pendingCompactionSessions)
  - continuation/context-pressure.ts:44 (lastFiredBand)
  - continuation/delegate-dispatch.ts:33 (hedgeTimers)
  - continuation/delegate-store.ts:341 (delayedReservations)
  - continuation/state.ts:14, 17, 72 (timer registries + init)
  - reply/post-compaction-delegate-dispatch.ts:504 (entryIds, ephemeral)

Load-bearing verified: sabotage with unallowlisted `new Map` in
`continuation/state.ts` → 1/1 fail with canonical 'NOT in the
volatile-Map allowlist' message. Restored → 1/1 pass.

Closes #441

💡 Codex Review

void dispatchToolDelegates({
sessionKey,
chainState: refreshedChainState,
ctx: params.ctx,
maxChainLength: params.maxChainLength,
loadFreshChainState: params.loadFreshChainState,
}).catch((err) => {

P1 Badge Persist chain state after hedge-triggered delegate dispatch

Handle the dispatchToolDelegates result in the hedge timer path and persist the returned chainState; right now the callback fire-and-forgets the promise and drops the updated counter/tokens. This means delayed delegates that fire in quiet channels (no subsequent turn to run agent-runner/followup-runner persistence) can spawn successfully while continuationChainCount in session state remains stale, so later budget checks use an undercount and can exceed maxChainLength.

Per figs's directive 2026-05-01 ~19:50Z (path-(b) handoff-state-self-contained):
v3 candidate should carry awareness of OV-5 work in flight on canonical2 so
canonical-lineage drive doesn't discover OV-5 as a surprise during the merge.

Captures:
- What OV-5 is + why (volatile-Map allowlist guard-test for continuation surface)
- Two competing PRs: #464 (Elliott🌻 yesterday, stale base) + #505 (frond-scribe
  dispatched copilot today, current canonical2 base) — figs called "viable compare"
- 10 canonical2 allowlist anchors (file:line:symbol:type:restart-contract)
- Test file path: src/auto-reply/continuation/volatile-map-allowlist.test.ts
- v3 candidate carries identical continuation surface; test applies unchanged

Closes the OV-5 / canonical-lineage-handoff awareness gap from figs's earlier
"copilot needs to know about its content of finding RE: its v3 rebase" question.

🩸 Real-byte-walk per figs's "quality only deliverable, zero shortcuts" directive (2026-05-02 ship-evening unfucking).

Verdict: CLOSE-WITH-REASON, defer to v29-uptake portfolio (#541).

This PR adds src/auto-reply/continuation/volatile-map-allowlist.test.ts (static guard scanning §4 continuation surface for unallowlisted volatile Maps).

Substance state across branches:

Ancestor-check evidence:

git merge-base --is-ancestor a448042c2edd94a4e8ee86d5ed90a5ed9fe8e4cd <pr-464-head>
exit: 1  # WRONG basis (head doesn't include v2026.4.29)

Recommended path: close-with-reason here. The substance is live on canonical2 (#505) and falls under the v29-uptake portfolio in #541 — copilot is currently classifying canonical2 commits onto v29-base via PORT/ALREADY-ON-V3/DROP/CONFLICT. The volatile-map-allowlist guard should ride that uptake, not be separately re-revived from this PR's branch.

Per cohort tetrachotomy (banked tonight in MEMORY.md): this is case-(3) supersession via canonical2-#505 + v29-uptake-pending — distinct from "supersession via v29 direct landing" but operationally identical (close-with-reason, don't re-port).

🌻 CLOSE-WITH-REASON — SUPERSEDED-BY-LANDING.

Byte-walk (elliott-seat, 2026-05-03):

Cohort cosign chain: 🩸 byte-walk + recommendation 2026-05-02 → 🌫️ ack-with-shape 2026-05-03 → 🌻 v5.2 byte-confirmation + close 2026-05-03.

No follow-up PR needed; substance is on v5.2/canonical. The companion test-trap PRs cited in the original PR body (#462 mode-only trap, #463 descriptor closed-set trap) are likely in the same family — separate determination per their own bases.
