Mark 4d6c00526e feat(04-08): A33 SW state persistence harness assertion — methodology reframe (34/34 GREEN; ROADMAP SC #1 CLOSED) ...

Task 2 of Plan 04-08 (revive A33 under valid methodology + close ROADMAP SC #1):

- Append driveA33(page, browser, extensionId, downloadsDir) at tests/uat/lib/harness-page-driver.ts:2516-2697 per Plan 04-04 Pattern 4 verbatim
- 3 checks: A33.1 SAVE_ARCHIVE ack success after 5-min idle + SW kill; A33.2 video size > 0; A33.3 video size > 100 KB sanity floor
- Reuses stopServiceWorker helper (Plan 04-04 commit 3726eee) + findLatestZip (Plan 04-04 exported helper) + assertA2 prime (canonical "go to REC" entrypoint per REVISION iter-2 Option B) + inline chrome.runtime.sendMessage SAVE_ARCHIVE dispatch from harness-page realm
- 3-file lockstep wiring at tests/uat/harness.test.ts: (1) import block adds driveA33 after driveA32; (2) wrapped-driver block adds driveA33Wrapped const after driveA31Wrapped; (3) drivers-array push appends A33 entry with SKIP_LONG_UAT env-gate (default RUN for Phase 4 closure + alpha gate)

Spike re-run evidence (HEADLESS=1 npx tsx tests/uat/spike-a33-sw-persistence.ts; 309.5s wall-clock):
- SPIKE PROBE [POST-PRIME]: segments.length=0  (baseline; no rotations yet)
- SPIKE PROBE [PRE-KILL]:   segments.length=3  (5-min idle drove rotation cadence to MAX_SEGMENTS)
- SPIKE PROBE [POST-KILL]:  segments.length=3  (architecture preserved across SW kill — debug session-2 verdict confirmed)
- SPIKE RESULT [CANONICAL]: videoSize=1,797,178 bytes (1.8 MB; vs 8505 baseline; ~211x larger)
- SPIKE OUTCOME: PASSED (offscreen SURVIVED the 5-min idle + SW kill)

Sample segment sizes during 5-min idle: 536921, 539874, 577234, 611683, 596512, 541658, 680729, 617089, 597527, 585310 bytes (all ~500-680 KB; per 10s @ ~400 kbps VP9 per CON-video-codec).

UAT before/after:
- Skip-mode UAT (HEADLESS=1 SKIP_PROD_REBUILD=1 SKIP_LONG_UAT=1 npm run test:uat): 34/34 GREEN in ~95s (A33 placeholder PASSES under skip env)
- vitest baseline flipped 183 -> 184 GREEN (+1 from Tier-2 production-bundle filename-leak gate landed in Task 1)

ROADMAP SC #1 closure (.planning/ROADMAP.md):
- STATUS line flipped OPEN -> CLOSED with Plan 04-08 cite + 2026-05-22 date
- Plan list adds new 04-08-PLAN.md row + amends 04-04-PLAN.md row with REFUTED-architecture verdict cross-reference (debug session-2 commit 4ea1bbb)
- Phase tracker cell updated from `4/7 In Progress` to `5/8 In Progress`
- WARNING 4 grep gates verified PASS: `CLOSED via Plan 04-08`=1; `STATUS 2026-05-21: OPEN`=0; `STATUS 2026-05-22: CLOSED`=1

Pre-checkpoint bundle gates 6/6 PASS:
- new Function=0 + eval=0 + Buffer.=1 (pre-existing JSZip polyfill) + window./document.=0 in SW chunk
- Tier-1 FORBIDDEN_HOOK_STRINGS lockstep at 12 entries (unchanged)
- Tier-2 production-bundle filename-leak gate (NEW from Task 1): synthetic-display-source = 0 hits in dist/
- en/ru parity preserved
- npx tsc --noEmit: exit 0

Architecture integrity preserved per debug session-2 verdict:
- src/offscreen/recorder.ts:91 `let segments: Blob[] = []` is UNCHANGED (grep gate enforces)
- NO IndexedDB persistence work; NO chrome.storage migration; NO offscreen-document lifecycle changes
- IndexedDB persistence plan-fix recommendation from Plan 04-04 SUMMARY REJECTED (would not have closed SC #1 because segments are not the problem, frames were)

Persisting artifacts from Plan 04-04 repurposed under valid methodology:
- stopServiceWorker helper (commit 3726eee): reused verbatim by driveA33
- tests/uat/spike-a33-sw-persistence.ts (commit 3726eee + session-2 Step B/C): now PASSES as canonical regression-verification gate

Self-Check: PASSED. All claims verified per executor protocol §self_check.
