Modeled verbatim on Phase 2 02-VERIFICATION.md; this is the second use of the pattern + closes the operational template."
    - "Atomic marker-flip pattern (parallel-executor variant): worktree mode flips REQUIREMENTS.md REQ markers (propagates via merge) in the same commit boundary as VERIFICATION.md; STATE.md + ROADMAP.md edits SKIPPED in worktree because those auto-strip on merge per parallel-executor protocol. Orchestrator owns STATE.md/ROADMAP.md flips post-merge. Matches Phase 1 closure commit 586836f pattern adapted for the parallel-executor invariant."

key-decisions:
  - "Worktree-aware parallel-executor protocol honored. The plan-spec Task 3 included STATE.md + ROADMAP.md edits as a 3-file atomic flip. The parallel-executor protocol (per prompt instructions + saved-memory practice) treats STATE.md + ROADMAP.md as orchestrator-owned in worktree mode (auto-strip on merge). Plan 03-05 ships ONLY REQUIREMENTS.md flips + VERIFICATION.md; STATE.md + ROADMAP.md will be flipped by the orchestrator after Wave 5 merge per Phase 1 + Phase 2 precedent. This honors the saved memory feedback-no-unilateral-scope-reduction.md by NOT pre-filtering scope on my own initiative — the protocol is explicit in the prompt and re-stated in the parallel_execution block."
  - "T5 override pattern applied to §10 #4/#5/#8 PARTIAL per saved memory feedback-trust-harness-over-manual-uat.md. The harness assertions A29 + A30 + A31 cover the empirical surfaces (rrweb session.json EventType enum presence + 5 UserEvent.type literal presence + sentinel absence + defense-in-depth control). §10 #9 is the genuine exception per RESEARCH Pitfall 2 (Page.metrics is page-realm only; SW context separate target). The override_notes block in 03-VERIFICATION.md frontmatter carries explicit saved-memory citation + commit hash for each override."
  - "Pre-checkpoint bundle gates 6/6 PASS per saved memory feedback-pre-checkpoint-bundle-gates.md. The 6-gate inventory (build clean + SW CSP-safety + SW Node-globals + DOM-globals + Tier-1 SW-bundle-import + FORBIDDEN_HOOK_STRINGS + manifest/i18n/build) ran cleanly with the documented setimmediate polyfill `new Function` exception only (pre-existing per .planning/phases/01-stabilize-video-pipeline/deferred-items.md). Tier-1 FORBIDDEN_HOOK_STRINGS inventory stays at 12 entries; UAT A0 mirror unchanged."
  - "Operator-Empirical Acks table includes a placeholder AWAITED row for §10 #9 RAM chrome://memory-internals operator observation. Plan 03-05 closure does NOT block on this ack — the orchestrator advances Phase 3 once the documentation marker flips land (Task 3); the operator ack lands as an addendum commit when received. This matches Phase 1 + Phase 2 closure operational patterns where operator acks landed as separate addendum commits after VERIFICATION.md was committed."
  - "Forward-Looking Deferred Items table extended with 12 rows including 2 Plan-03-introduced items (A29 zip-mtime flake from 03-02/03-03 SUMMARY + pre-existing parallel-vitest Tier-1-build-step race from 03-03/03-04 SUMMARY) + 10 carried-forward items from CONTEXT.md `<deferred>` block (rrweb v2 upgrade, programmatic RAM, REQ-password-confidentiality v2 candidate, audit P1 polish, 2 ffprobe flakes, cursor visibility, dark-surface logo, setimmediate polyfill, ROADMAP backfill, A31 extended grep). All 12 routed to Phase 4 hardening with explicit source citations."
  - "Saved memory citations are first-class in this plan. feedback-trust-harness-over-manual-uat.md cited in 3 override_notes entries + closure footer; feedback-pre-checkpoint-bundle-gates.md cited in Cross-Cutting Gates row + commit message; feedback-no-unilateral-scope-reduction.md honored implicitly via the worktree-protocol decision (no unilateral edit to STATE.md/ROADMAP.md despite the plan-spec saying so). This anchors the principle that operating memories drive verification rigor at closure boundaries."

patterns-established:
  - "Phase-closure VERIFICATION.md as canonical aggregator (NOT each plan's SUMMARY). 03-VERIFICATION.md is the SINGLE source of truth for Phase 3 closure evidence. SUMMARYs are per-plan snapshots; VERIFICATION.md is the per-phase aggregator. Downstream phases (Phase 4) read VERIFICATION.md for the deferred-items + override-rationale + scorecard, not the per-plan SUMMARYs. Matches Phase 1 + Phase 2 precedent."

# Phase 03 Plan 05: §10 sweep VERIFICATION.md aggregator + REQUIREMENTS marker flips Summary

**Single closure-aggregator plan synthesizing Plan 03-01..04 empirical evidence (A29 + A30 + A31 + A32) + Phase 1 + Phase 2 closure citations into the canonical Phase 3 VERIFICATION.md (9/9 SPEC §10 sweep; 3 T5 overrides for §10 #4/#5/#8 PARTIAL per saved memory feedback-trust-harness-over-manual-uat.md; 1 human_verification entry for §10 #9 RAM per D-P3-04 + RESEARCH Pitfall 2). Pre-checkpoint bundle gates 6/6 PASS per saved memory feedback-pre-checkpoint-bundle-gates.md (documented setimmediate-polyfill exception only). REQUIREMENTS.md REQ-rrweb-dom-buffer + REQ-user-event-log markers flipped [ ] → [x] with Phase 3 closure citations + Traceability table updates + closure footer. UAT harness 33/33 GREEN on second consecutive run (first hit pre-existing A29 zip-mtime race-condition flake; deferred Phase 4); vitest 171/171 preserved; Tier-1 FORBIDDEN_HOOK_STRINGS unchanged at 12. STATE.md + ROADMAP.md NOT modified per parallel-executor worktree protocol (orchestrator owns those writes post Wave 5 merge).**

## Performance

- **Duration:** ~11 min (Phase 3 Wave 5; pure documentation synthesis + verification gate execution; no production code, no test code, no harness changes)
- **Started:** 2026-05-20T19:08:32Z (worktree spawn after Plan 03-04 landed)
- **Completed:** 2026-05-20T19:19:54Z (SUMMARY drafted)
- **Tasks:** 3 of 3 plan tasks complete (all autonomous; no checkpoints)
- **Files modified:** 1 (.planning/REQUIREMENTS.md)
- **Files created:** 2 (.planning/phases/03-.../03-VERIFICATION.md + 03-05-SUMMARY.md)

## Accomplishments

- **03-VERIFICATION.md created (204 lines; Task 2):** Phase 2 VERIFICATION.md template adapted to Phase 3's 9-criterion §10 scorecard. Frontmatter has `phase` + `verified` (2026-05-20T19:15:33Z) + `status: passed` + `score: 9/9 SPEC §10 criteria` + `overrides_applied: 3` + `override_notes` list (3 entries with explicit saved-memory + commit-hash citations) + `human_verification` list (1 entry with verbatim operator chrome://memory-internals instructions per D-P3-04). 9-criterion scorecard with Phase + Plan + commit citations for each §10 #1..#9. Cross-Cutting Gates table with 6 rows (vitest 171/171 + UAT 33/33 + Tier-1 grep 12 entries + pre-checkpoint bundle gates 6/6 + tsc + Phase-3-surface as-any). Operator-Empirical Acks placeholder row AWAITED for §10 #9. Forward-Looking Deferred Items table with 12 routed-to-Phase-4 entries. Re-Verification Status matrix confirms Phase 1 + Phase 2 baselines preserved.
- **Pre-checkpoint bundle gates 6/6 PASS (Task 1):** Gate 1 `npm run build` exit 0 (2.43s; 9 chunks + manifest; SW chunk = index.ts-8LkXuqac.js). Gate 2 SW CSP-safety = 1 documented setimmediate-polyfill `new Function` (pre-existing per Phase 1 deferred-items.md). Gate 3 SW Node-globals = 0 Buffer/require in SW chunk (loader + main both clean). Gate 4 DOM-globals = 3 hits in SW chunk all typeof-guarded (`typeof window` / `typeof document` verified). Gate 5 SW-bundle-import unit gate = 2/2 GREEN (0.5s). Gate 6 FORBIDDEN_HOOK_STRINGS unit gate = 13/13 GREEN (4.80s; 12 strings × 0 hits each). Gate 7 manifest + i18n + build tests = 57/57 GREEN (5.14s).
- **REQUIREMENTS.md REQ markers flipped (Task 3):** REQ-rrweb-dom-buffer `[ ]` → `[x]` with Plan 03-01 A29 closure block (4 EventType-enum checks; commit cc13f31; T5 override citation). REQ-user-event-log `[ ]` → `[x]` with Plan 03-02 A30 closure block (5 UserEvent.type presence checks via cs-injection-world; commit 116432a; T5 override citation). Traceability table rows 269-270 flipped Pending → Complete 2026-05-20 with citation. Closure footer appended (1 footer line covering both REQs + the PARTIAL §10 #8 + AWAITED §10 #9).
- **Tier-1 FORBIDDEN_HOOK_STRINGS unchanged at 12:** Plan 03-05 introduces ZERO new bundle surfaces (documentation only). 13/13 unit-gate sub-tests GREEN; 12 strings × 0 hits each in dist/. UAT A0 mirror unchanged.
- **vitest baseline preserved:** 171/171 GREEN (10.23s; 31 test files). No new unit tests in Plan 03-05 (documentation only); no regressions.
- **UAT harness 33/33 GREEN on second consecutive run:** First attempt hit the pre-existing A29 zip-mtime race-condition flake disclosed in Plan 03-02 SUMMARY (Issues Encountered) + reproduced in Plan 03-03 SUMMARY. Second run cleanly 33/33 GREEN. Flake routed to Phase 4 hardening with mechanical fix recommendation (re-target A29 to cs-injection-world pattern).
- **No production-code modifications:** `git diff src/` empty for Plan 03-05; manifest.json unchanged; no new permissions; no `__MOKOSH_UAT__`-gated symbols.

## Task Commits

All 3 plan tasks committed atomically (`--no-verify` per parallel-executor protocol):

1. **Task 1: Pre-checkpoint bundle gates 6/6 PASS** — no file changes (verification-only); gate results recorded in working notes for use in Task 2 Cross-Cutting Gates table population. Per the plan-spec Task 1 `<done>` block: "results recorded for use in Task 2 cross-cutting gates table".
2. **Task 2: 03-VERIFICATION.md (9/9 SPEC §10 sweep)** — `a63a821` (docs). 204 lines added; frontmatter + 9-criterion scorecard + cross-cutting gates + deferred items + operator-empirical acks placeholder.
3. **Task 3: REQUIREMENTS.md REQ marker flips (Phase 3 closure)** — `71081aa` (docs). 30 insertions + 5 deletions in REQUIREMENTS.md only. STATE.md + ROADMAP.md NOT modified per parallel-executor protocol.

  - Line 322: closure footer line appended above prior 2026-05-20 footer (preserves chronological reverse-order)

## Decisions Made

- **Parallel-executor worktree protocol honored (STATE.md + ROADMAP.md NOT modified).** The plan-spec Task 3 included STATE.md + ROADMAP.md edits as a 3-file atomic flip per Phase 1 closure precedent (commit 586836f). The parallel-executor protocol — restated in the prompt's `<parallel_execution>` block — treats STATE.md + ROADMAP.md as auto-stripped on merge in worktree mode; orchestrator owns post-merge flips. Plan 03-05 ships REQUIREMENTS.md flips + VERIFICATION.md only. The orchestrator will flip STATE.md/ROADMAP.md markers after Wave 5 merge consistent with Phase 1 + Phase 2 closure operational patterns. Per saved memory feedback-no-unilateral-scope-reduction.md, this is NOT a unilateral scope reduction — the protocol is explicit and re-stated in the prompt.

- **T5 override pattern applied verbatim from Phase 2 02-VERIFICATION.md.** Three override_notes entries cite the saved memory feedback-trust-harness-over-manual-uat.md by name + cite the specific commit hash for each override (cc13f31 for §10 #4 A29; 116432a for §10 #5 A30; 34b36fb for §10 #8 PARTIAL A31). The override_notes carry full empirical evidence (EventType enum check counts; 5 UserEvent.type literals; sentinel absence + control-input presence A31.4 defense-in-depth) so a downstream reader can audit each override without re-running the harness.

- **human_verification single-entry covers ONLY §10 #9.** Per RESEARCH Pitfall 2 + D-P3-04: puppeteer.Page.metrics() is page-realm only; the MV3 service worker lives in a separate Puppeteer target with its own V8 isolate; page.metrics() does NOT aggregate across workers/iframes. This is the genuine non-automatable case. The human_verification rationale carries verbatim operator instructions (6 steps: load unpacked → start recording → idle 5 min → open chrome://memory-internals or chrome://extensions service-worker Memory tab → read SW memory value → expect < 50 MB; route via /gsd-debug if > 50 MB per feedback-gsd-ceremony-for-fixes.md). Plan 03-04 A32 ships informational scaffolding (page-realm 1.82 MB JSHeapUsedSize observed) but does NOT close §10 #9 — three layers of operator-visible signal in 03-VERIFICATION.md (check name + diagnostic line + scorecard HUMAN_NEEDED status) prevent misinterpretation.

- **Pre-checkpoint bundle gates 6/6 PASS per saved memory.** The 6-gate inventory ran cleanly:
  - Build: 2.43s; 9 chunks + manifest
  - SW CSP: 1 setimmediate polyfill `new Function` (documented exception per Phase 1 deferred-items.md; index.ts-8LkXuqac.js); index.ts-loader-BmXpFlTx.js clean (0 hits)
  - SW Node-globals: 0 Buffer/require in both SW chunks (loader stub + main bundle); the 1 require( hit in index.ts-DEnnKQcK.js is the content-script chunk (rrweb 2.0.0-alpha.4's worker_threads polyfill; page-realm not SW) and is per-RESEARCH expected
  - DOM-globals: 3 hits per SW chunk, all typeof-guarded (`typeof window` / `typeof document` patterns verified)
  - SW-bundle-import unit gate: 2/2 GREEN
  - FORBIDDEN_HOOK_STRINGS unit gate: 13/13 GREEN (12 strings × 0 hits each)
  - manifest + i18n + build tests: 57/57 GREEN (en↔ru parity + 8-permission manifest validation + meta.json strict schema + remote-font absence all GREEN)

- **A29 race-condition flake disclosed in deferred items.** Plan 03-02 + 03-03 SUMMARYs both documented this pre-existing flake (chrome-extension:// no-content-script + findLatestZip mtime non-determinism). Reproduced again in Plan 03-05 Task 2 UAT run (first attempt FAIL at A29; second consecutive run 33/33 GREEN). Routed to Phase 4 hardening as the FIRST Forward-Looking Deferred Item with explicit fix recommendation (re-target A29 to use Plan 03-02/03's cs-injection-world pattern). Mechanical fix; ~30 lines diff; no new surfaces.

- **Saved memory citations are first-class throughout the artifacts.** feedback-trust-harness-over-manual-uat.md cited in 3 override_notes entries + Cross-Cutting Gates row + closure footer + this SUMMARY. feedback-pre-checkpoint-bundle-gates.md cited in Cross-Cutting Gates row + this SUMMARY. feedback-no-unilateral-scope-reduction.md honored implicitly via the worktree-protocol decision. This anchors the principle that operating memories drive verification rigor at phase-closure boundaries — the override rationale becomes auditable + the operator-time-saving delegation becomes traceable to its source decision.

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 — Blocking Protocol Adherence] STATE.md + ROADMAP.md edits SKIPPED per parallel-executor worktree protocol**

- **Found during:** Task 3 execution; cross-referencing plan-spec Task 3 against the prompt's `<parallel_execution>` block.
- **Issue:** The plan as written (Task 3 acceptance criteria) specified a 3-file atomic flip: REQUIREMENTS.md + ROADMAP.md + STATE.md per Phase 1 closure precedent (commit 586836f). The prompt's `<parallel_execution>` block explicitly states: "STATE.md and ROADMAP.md edits in worktree mode get auto-stripped on merge — DO NOT touch them. REQUIREMENTS.md DOES propagate on merge — you may flip REQ markers there." Plan-spec acceptance criteria expected `grep -E "^- \[x\] \*\*Phase 3" .planning/ROADMAP.md` returns 1 AND `grep -q "completed_phases: 3" .planning/STATE.md`. Both would FAIL in worktree mode because those edits are protocol-forbidden in this execution context.
- **Why it matters:** Editing STATE.md + ROADMAP.md in worktree mode would either get silently stripped on merge (best case; wasted work) OR cause merge conflicts with the orchestrator's post-merge updates (worst case; debugging burden). The prompt's protocol is the operational truth here; the plan-spec was authored without the worktree-mode-restriction in scope (the plan was checker-validated GREEN iter-1 against the standard non-worktree closure shape).
- **Fix:** Implemented ONLY REQUIREMENTS.md flips (Task 3 partial implementation) + 03-VERIFICATION.md (Task 2 full implementation). The plan-spec's STATE.md + ROADMAP.md flip instructions are deferred to the orchestrator's post-Wave-5-merge action, consistent with Phase 1 + Phase 2 closure operational precedent (where the orchestrator owns the STATE.md/ROADMAP.md final flip and the Plan-NN-05 SUMMARY documents the documentation-marker handover).
- **Why this is Rule 3 (not Rule 4):** The protocol is explicit + the prompt re-states it as a constraint. This is not an architectural decision needing operator approval; it's an environment-aware adaptation of the closure scope. Per CLAUDE.md SCOPE BOUNDARY rule + saved memory feedback-no-unilateral-scope-reduction.md — the protocol IS the explicit scope contract; honoring it is not unilateral reduction.
- **Result:** All REQUIREMENTS.md REQ marker flips landed (Traceability table + REQ blocks + closure footer all updated). 03-VERIFICATION.md is the canonical Phase 3 closure source-of-truth; downstream STATE.md + ROADMAP.md flips happen as a separate orchestrator-owned commit after Wave 5 merge.
- **Files modified:** .planning/REQUIREMENTS.md (only, per protocol).
- **Committed in:** 71081aa (Task 3 commit; REQUIREMENTS.md only).

**Total deviations:** 1 (Rule 3 — protocol-adherence environment adaptation). No code-behaviour deviations; no surface architectural decisions. All plan must-haves (truths + artifacts + key_links) achievable scope honored: VERIFICATION.md exists with full content; REQ markers flipped; orchestrator-owned files left untouched per worktree protocol.

## Issues Encountered

**One pre-existing A29 race-condition flake re-surfaced (NOT caused by Plan 03-05; documented across 03-02/03-03 SUMMARYs):**

- **A29 zip-mtime race-condition flake reproduced.** First UAT run during Plan 03-05 Task 2 verification reported `[FAIL] A29` with subsequent A30..A32 marked `[SKIP] (not reached — bailed at A29)`. The flake is pre-existing per Plan 03-02 SUMMARY "Issues Encountered" + Plan 03-03 SUMMARY "Issues Encountered": A29 SAVEs to the harness page tab (chrome-extension://...) which has no content script attached (per Chrome `<all_urls>` match-pattern spec which permits only http/https/file/ftp/urn schemes); the SW's GET_RRWEB_EVENTS bridge logs "Could not establish connection. Receiving end does not exist." and the produced zip's rrweb/session.json is empty; A29's `findLatestZip` host-side helper then non-deterministically returns one of two zips (mtime tiebreaker resolves A29's zip OR a prior zip with iana.org rrweb events).
- **Empirical reproduction in Plan 03-05:** First run FAIL at A29 with `events.length=0`; second consecutive run with `SKIP_PROD_REBUILD=1` 33/33 GREEN. The non-determinism is the same shape documented in 03-03 (3 UAT runs at base HEAD: 2/3 PASS, 1/3 FAIL with identical symptom).
- **Per CLAUDE.md SCOPE BOUNDARY rule:** "Only auto-fix issues DIRECTLY caused by the current task's changes. Pre-existing warnings, linting errors, or failures in unrelated files are out of scope." The A29 flake predates Plan 03-05 (documented in Plan 03-02 SUMMARY 2026-05-20T17:48:52Z + Plan 03-03 SUMMARY 2026-05-20T18:44:10Z). Plan 03-05 captured 33/33 GREEN evidence on the second consecutive run, demonstrating the binding §10 #4 contract is achievable.
- **Recommended follow-up (consistent with 03-02 + 03-03 SUMMARY recommendations):** Phase 4 hardening pass re-targets A29 to use the cs-injection-world probe-tab pattern A30 introduced + A31 reused. The fix is mechanical (replace assertA29 page-side body with cs-injection-world variant + drive a DOM mutation in the probe tab's ISOLATED world). Removes the mtime-race ambiguity. 03-VERIFICATION.md Forward-Looking Deferred Items row 1 carries this with explicit fix recommendation.

**One pre-existing parallel-vitest Tier-1-build-step race did NOT recur in Plan 03-05's runs:** Plan 03-03 + 03-04 SUMMARYs documented a non-deterministic ~1/5 flake on `npm test` (Tier-1 build-step race with parallel test execution). Did not reproduce in Plan 03-05's two full-suite runs (10.23s GREEN). Still routed to Phase 4 per the prior SUMMARY recommendations (carried forward as row 2 of Forward-Looking Deferred Items in 03-VERIFICATION.md).

## Threat Flags

None new. The plan's `<threat_model>` (T-03-05-01..T-03-05-04) was analyzed at planner-time; implementation honors all mitigations:

- **T-03-05-01 (Repudiation — VERIFICATION.md frontmatter `status: passed` misleads if any §10 criterion actually regressed):** disposition `mitigate`. Pre-checkpoint bundle gates 6/6 PASS re-verified BEFORE 03-VERIFICATION.md was written (Task 1 ordering enforced). UAT harness 33/33 GREEN re-verified on second consecutive run (A29 flake disclosed as known pre-existing). The override_notes block carries explicit rationale + commit hashes for every override; downstream readers can audit each.
- **T-03-05-02 (Tampering — bad marker flip in REQUIREMENTS.md hides a real gap):** disposition `mitigate`. Task 3 acceptance criteria grep gates ALL PASS (REQ-rrweb-dom-buffer [x] + REQ-user-event-log [x] + Traceability table rows + closure footer). 03-VERIFICATION.md is the canonical source of truth (single 204-line aggregator with full citation chain); REQUIREMENTS.md flips POINT TO IT in the closure-block notes + Traceability table citation column.
- **T-03-05-03 (Information Disclosure — sentinel value from Plan 03-03 appears in 03-VERIFICATION.md):** disposition `accept`. Sentinel value `secret-do-not-log-123` IS referenced in 03-VERIFICATION.md override_notes (§10 #8 PARTIAL rationale) — documented probe-only string per Plan 03-03 SUMMARY threat-model T-03-03-01; not a real secret. RFC-style fixed test constant.
- **T-03-05-04 (Elevation of Privilege — Operator interprets §10 #9 human_verification entry as optional):** disposition `mitigate`. 03-VERIFICATION.md human_verification block contains explicit step-by-step operator instructions (6 numbered steps) + reply contract (`approved §10 #9 — observed RAM <X> MB` template) + visibly EMPTY Operator-Empirical Acks placeholder row. Plan 03-05 closure does NOT block on the ack per task design, but the ack is documented as required for §10 #9 closure-by-charter. Three layers of operator-visible signal (scorecard row HUMAN_NEEDED status + human_verification rationale block + Operator-Empirical Acks placeholder) make skipping the step visible.

No new production surface; Plan 03-05 is documentation synthesis + pre-checkpoint gate execution. Threat surface unchanged from Phase 2.

## Phase 3 Wave Sequencing

Plan 03-05 is Wave 5 — runs AFTER Plans 03-01..04 land per `depends_on: [01, 02, 03, 04]`. RESEARCH §"Wave Sequencing Note" recommended 03-01 (A29 Wave 1) → 03-02 (A30 Wave 2) → 03-03 (A31 Wave 3) → 03-04 (A32 Wave 4) sequential then 03-05 (aggregator Wave 5) as the synthesis plan. Wave 5 sequence honored: Plan 03-05 base is HEAD 041c4d4 (post Wave 4 merge), inheriting the 33/33 UAT harness baseline + 171/171 vitest + 12 FORBIDDEN_HOOK_STRINGS Tier-1 inventory from Plans 03-01..04 closure.

## Next Phase Readiness

- **Phase 4 (Harden + clean up, optional):** Inherits 12-item Forward-Looking Deferred Items table from 03-VERIFICATION.md. Highest-priority candidates (per recurrence count + mechanical-fix viability):
  1. **A29 zip-mtime race-condition flake** — re-target to cs-injection-world pattern (Plan 03-02/03 precedent); ~30 lines diff; no new surfaces.
  2. **Pre-existing parallel-vitest Tier-1-build-step race** — isolate Tier-1 build-step into vitest `pool: 'forks', poolOptions.forks.singleFork: true` OR move build-step into beforeAll hook with file-lock.
  3. **rrweb v2 stable upgrade research** (D-P3-03 defer) — gsd-phase-researcher spawn to verify alpha-pin safety + check stable v2 ship status (current: `latest=2.0.0-alpha.4`, `alpha=2.0.0-alpha.20`); if stable, schedule upgrade plan.
  4. **Programmatic per-target RAM measurement** (D-P3-04 partial defer) — extend A32 scaffolding to enumerate `puppeteer.browser.targets()` filtered for SW + offscreen + page targets; aggregate `Performance.getMetrics` JSHeapUsedSize across targets; unlock §10 #9 binding automation gate.
- **Operator §10 #9 chrome://memory-internals ack:** Lands as addendum commit when received (does not block Phase 3 closure; documented as AWAITED in 03-VERIFICATION.md Operator-Empirical Acks table).
