- ROADMAP.md Phase 1 row [ ] → [x] with closure-arc summary
- REQUIREMENTS.md REQ-video-ring-buffer In-progress → Complete 2026-05-20
- VERIFICATION.md committed (orchestrator-bundle pattern per verifier
protocol)
Forward-looking deferred (NOT gaps):
- Phase 2: REQ-rrweb-dom-buffer + REQ-user-event-log +
REQ-password-confidentiality (audit P0 #6)
- Phase 5 hardening: getDisplayMedia cursor visibility; setimmediate
polyfill new Function pre-existing; tabs permission gap; dark-surface
logo contrast; 2 ffprobe/ffmpeg test flakes
Phase 2 (Stabilize DOM + event-capture privacy) kickoff pending.

# Phase 1 Verification — Stabilize Video Pipeline (Goal-Backward Audit)
|
||
|
||
**Verdict: ACHIEVED.** 14/14 functional plans landed; all REQs & decisions verified against codebase HEAD `d1ef77a`.
|
||
|
||
## Goal (verbatim, ROADMAP.md + PROJECT.md)
|
||
|
||
Stabilize video pipeline: continuous 30 s whole-desktop ring buffer via `getDisplayMedia` in offscreen; playable single-EBML WebM remux on export; toolbar + notification + first-install welcome activation; brand-fit operator-facing surfaces.
|
||
|
||
## Per-Requirement Scorecard

|
||
| 5 | D-01 whole-desktop charter | `recorder.ts:284-291` — `{video:{displaySurface:'monitor',cursor:'always'}, monitorTypeSurfaces:'include', audio:false}`; `:302-323` post-grant validation throws `wrong-display-surface` on mismatch; A3 + A23 harness GREEN | PASS |
|
||
| 6 | D-06 always-on charter (Amendment 3 reversal) | `src/background/index.ts:722-740` docstring locks no-finally; `:830-834` explicit NO finally block; `tests/background/save-archive-does-not-stop-recording.test.ts` (inverted); harness A14 inverted (commit 1baaf45) | PASS |

|
||
| 10 | SW respawn safety (CR-03) | `src/background/index.ts:962-986` `hasDocument()` + early-resolve `offscreenReadyResolve` on detected pre-existing offscreen; long-lived port (D-17, PORT_PING_MS=25_000) | PASS |
|
||
| 11 | Offscreen duality collapsed (P0-1) | `ls offscreen/` → ENOENT; `grep copy-offscreen vite.config.ts` → 0; `dist/src/offscreen/index.html` single source via crxjs rollupOptions.input | PASS |
|
||
|
||
## Cross-Cutting Gates
|
||
|
||
| Gate | Evidence | Status |
|
||
|---|---|---|
|
||
| vitest | 28 files / **153 tests / 153 GREEN** (SKIP_BUILD=1 after fresh `npm run build` — first-pass had 2 build-dependent + 1 known ffprobe flake, both resolved post-build) | PASS |
|
||
| UAT harness | 24 drivers (A0 grep gate + A1..A14 + A15..A17 + A18..A22 + A23); SUMMARY 01-10 verifies 24/24 GREEN | PASS |
|
||
| Tier-1 grep gate | 12 FORBIDDEN_HOOK_STRINGS (matches documented baseline); `dist/` contains 0 `__mokoshTest`/`installFakeDisplayMedia`/etc. | PASS |
|
||
| Pre-checkpoint bundle gates | 0 `googleapis`/`https://fonts` in dist; 0 test-hook leaks; manifest validation + en↔ru parity tests GREEN | PASS |
|
||
| tsc | `npx tsc --noEmit` exit 0 | PASS |
|
||
| Phase 1 surface `as any` / `@ts-ignore` | 0 in `src/offscreen/`, `src/background/index.ts`, `src/shared/`, `src/welcome/`, `src/popup/` (only comments mentioning the absence; `src/content/` matches are Phase 2 territory) | PASS |
|
||
|
||
## 7 P0 Audit Defects — Traceability
|
||
|
||
| P0 # | Defect | Closed by | Status |
|
||
|---|---|---|---|
|
||
| 1 | Offscreen duality (`offscreen/index.ts` + vite inline) | Plans 01-03 + 01-06 | CLOSED |
|
||
| 2 | MediaRecorder shadow bug | Plan 01-03 | CLOSED |
|
||
| 3 | WebM ring buffer 200ms→2000ms + playability | Plans 01-03/04/07 + D-13 + Plan 01-08 D-14-remux | CLOSED |
|
||
| 4 | Always-on capture (`onActivated`/`onUpdated`) | Plan 01-05 SW shrink + Plan 01-09 onStartup notification + Amendment 3 always-on charter | CLOSED (architecturally; `chrome.tabs.onActivated`/`onUpdated` absent — `grep` exit 1 — replaced by single MediaStream across rotations via D-15 amended) |
|
||
| 5 | tabCapture user gesture | Plan 01-09 D-01 obviation via `getDisplayMedia` in offscreen + toolbar `chrome.action.onClicked` + notification onClicked paths | CLOSED |
|
||
| 6 | rrweb data-sensitive masking | Phase 2 (deferred per REQUIREMENTS.md line 220) | DEFERRED to Phase 2 (out of Phase 1 scope) |
|
||
| 7 | base64 data: URL download | Plan 01-08 webm-remux + JSZip; Note: `downloadArchive` at `src/background/index.ts:709-710` still uses `data:application/zip;base64,` URL via `blobToBase64` (REVIEW-FIX WR-08 single-source) — accepted Phase 1 trade-off; Phase 3 owns Blob-URL minted in offscreen per ROADMAP line 27 | CLOSED-in-scope (Blob-URL refinement is Phase 3 P0-6 territory) |
|
||
|
||
## Operator-Empirical Acks (verbatim + commit refs)
|
||
|
||
| Date | Plan | Operator response | Commit |
|
||
|---|---|---|---|
|
||
| 2026-05-15 | 01-07 (D-12 + A3 closure) | Chrome playback clean, ffmpeg dry-run exit 0 | cd61cbc (fixture) |
|
||
| 2026-05-19 | 01-13 (harness UAT Task 9) | "all good" (recovery + restart-after-click) | 9c5ff8b + 1baaf45 |
|
||
| 2026-05-20 | 01-12 (Wave 7 brand-fit) | "all good" (toolbar Loom icon, popup palette, manifest:name resolution EN+RU, Lora display, chrome.i18n notification copy) | f319c7d + 66e6f50 |
|
||
| 2026-05-20 | 01-10 (cycle-2 onboarding) | "All good" (welcome page + canonical mark + Lora hero + Cyrillic tagline + onStartup CTA + notification.onClicked → startVideoCapture + reload-does-not-re-open + re-install branch) | 52dc2e6 + d1ef77a |
|
||
| 2026-05-20 | 01-10 (cycle-2 brand-rename follow-up) | (same-day brand-polish ack on `d21ed17`) | d21ed17 |
|
||
|
||
## Initial-Pass Residue (May 16) — Now Closed
|
||
|
||
The May 16 initial verification flagged 3 operator-side items as `human_needed`. All resolved by subsequent plans + operator UAT:
|
||
|
||
1. **OPR-1** (getDisplayMedia picker grant) → Plan 01-09 + Plan 01-14 ship `displaySurface:'monitor' + monitorTypeSurfaces:'include'`; operator empirically grants via picker; A3 + A23 harness GREEN.
|
||
2. **OPR-2** (continuous capture across tab switches) → Plan 01-09 D-15-display-surface confirms no per-tab re-acquisition; A11 buffer-continuity harness GREEN over 35 s wait.
|
||
3. **OPR-3** (SW idle-unload survival) → Plan 01-04 long-lived port + CR-03 fix verified; harness A2 (toolbar→record) reaches GREEN after SW respawn cycles.
|
||
|
||
## Documentation Drift (NOT a gap — orchestrator marker-flip territory)
|
||
|
||
REQUIREMENTS.md line 218 traceability table row reads "In progress (reopened 2026-05-16…)" but line 19 already shows `[x]` and SUMMARY chain + footer note (line 244) confirm the closure. STATE.md `progress.completed_phases: 0` and ROADMAP.md Phase 1 row `[ ]` are similarly pending marker flip. This is the explicit "Phase 1 final-closure marker flip pending" task the orchestrator owns post-verification per STATE.md `stopped_at` field.
|
||
|
||
## Forward-Looking Deferred Items (NOT gaps)
|
||
|
||
| Item | Owner | Source |
|
||
|---|---|---|
|
||
| REQ-rrweb-dom-buffer + REQ-user-event-log + REQ-password-confidentiality (P0 #6) | Phase 2 | REQUIREMENTS.md lines 220-222 |
|
||
| Popup state machine + base64→Blob URL (P0-4 + P0-6) | Phase 3 | ROADMAP.md line 27 |
|
||
| SPEC §10 full smoke pass (#1 install + #6 <5s latency + #8 password + #9 RAM) | Phase 4 | ROADMAP.md line 28 |
|
||
| getDisplayMedia cursor visibility refinement (already mitigated via `cursor:'always'` in Plan 01-09 — but Phase 5 refinement remains for picker-UI polish) | Phase 5 | STATE.md line 187 |
|
||
| setimmediate polyfill `new Function` in SW chunk | Phase 5 | deferred-items.md (pre-existing across Phase 1 history) |
|
||
| `tabs` permission gap | Phase 5 | 01-13-SUMMARY.md line 186 |
|
||
| 2 ffprobe/ffmpeg test flakes (build-dependent + frame-count timeout) | Phase 5 | This verification (153/153 GREEN with SKIP_BUILD=1; flakes are test-harness fragility, not production-code bugs) |
|
||
| Dark-surface logo contrast | Phase 5 | (designer follow-up) |
|
||
| ROADMAP 01-08..01-13 backfill verification | Phase 5 | 01-13-SUMMARY.md line 185 (now backfilled in ROADMAP lines 81-87) |
|
||
|
||
## Per-Plan Closure Anchor Map
|
||
|
||
| Plan | Closed | Commit | Operator Ack |
|
||
|---|---|---|---|
|
||
| 01-01..01-07 | 2026-05-15 | cd61cbc + REQ flip | smoke.sh + Chrome playback |
|
||
| 01-08 (webm-remux) | 2026-05-17 | 9c5ff8b (closure) | (build-time gate; no UAT needed) |
|
||
| 01-09 (toolbar+badge+notification) | 2026-05-19 (functional via harness) + 2026-05-20 (CTA-text fix) | Multiple incl. 4bba679 + a2dfc8c | "all good" + cycle-2 |
|
||
| 01-10 (welcome tab) | 2026-05-20 | 52dc2e6 + d1ef77a | cycle-2 "All good" + brand-rename ack |
|
||
| 01-11 (spike-pivot) | 2026-05-18 | ba5474c | (architectural learning only) |
|
||
| 01-12 (design integration) | 2026-05-20 | f319c7d + 66e6f50 | brand-fit "all good" |
|
||
| 01-13 (UAT harness) | 2026-05-19 | 9c5ff8b | Task 9 "all good" |
|
||
| 01-14 (monitorTypeSurfaces) | 2026-05-19 | b467123 | (single-task; harness GREEN) |
|
||
|
||
---
|
||
|
||
**Final Verdict: Phase 1 goal ACHIEVED.** All must-haves verified in code; all operator empirical acks recorded; all deferred items routed to correct future phase. Orchestrator may flip `REQUIREMENTS.md`/`ROADMAP.md`/`STATE.md` markers + advance `progress.completed_phases: 0 → 1`.
