Mark 3f8e31a329 feat(04-06): A35 live-DOM inline-SVG harness check + A17.8 raw-source update + back-patch
Closes the iter-2 BLOCKER 1 resolution end-to-end: the inline-SVG
strategy now has HONEST automated coverage at two layers — source
contract (Task 1 unit tests + the narrowed A17.8 source-bundling
grep) and live-DOM cascade (the NEW host-side A35 harness assertion
that opens welcome.html as a real Puppeteer tab).

- tests/uat/extension-page-harness.ts (A17.8 NARROWED HONESTLY):
  swap the data:image/svg+xml URL-grep + .svg filename-grep target
  for a raw-source grep — A17.8 now asserts the welcome chunk JS
  contains the raw SVG signature `stroke="currentColor"` AND the
  canonical `viewBox="0 0 32 32"` (the `?raw` import's output). The
  explanatory comment block now DISAVOWS the live-DOM claim and
  points at the NEW A35 driver for the runtime injection + cascade
  proof. A17.8 is honest source-bundling only.
- tests/uat/lib/harness-page-driver.ts (NEW host-side driveA35):
  appended LAST per the iter-2 ADV-2C concern (any driver-pollution
  worry is moot since nothing reads A35's return value, AND
  welcomePage.close() in finally guarantees no tab leak). driveA35
  opens chrome-extension://<id>/src/welcome/welcome.html in a fresh
  browser.newPage() tab, waits for the `.welcome-hero__mark svg`
  selector at DOMContentLoaded, then runs a single page.evaluate()
  that reads four signals: A35.1 inline <svg> present, A35.2
  stroke=currentColor, A35.3 getComputedStyle().stroke resolves to
  a non-default colour (the real cascade proof), A35.4 no legacy
  <img> in the slot. Host-side pattern mirrors driveA32/A33/A34.
- tests/uat/harness.test.ts (orchestrator wiring):
  + driveA35 added to the import block from './lib/harness-page-driver'.
  + driveA35Wrapped closure capturing handles.browser + handles.extensionId
    (alongside driveA33Wrapped/driveA34Wrapped).
  + { name: 'A35', drive: driveA35Wrapped } appended as the LAST
    entry of the `drivers` array. Total auto-increments via
    `drivers.length + 1` (line 580) — no hardcoded count to bump.
  + Architecture banner string (line 283) refreshed with A33, A34,
    A35 inline (ADV-2A cosmetic advisory — banner was already stale
    pre-04-06; A33+A34 added at the same time).
- .planning/phases/01-stabilize-video-pipeline/01-07-SUMMARY.md
  (back-patch, DEFECT 2 resolution):
  Flipped 5 lines (22, 47, 82, 135, 205) that carried the now-stale
  "deferred to Phase 5" framing for cursor visibility — the
  `cursor: 'always'` constraint was opportunistically shipped in
  Plan 01-09 (recorder.ts:285) and is verified by Plan 04-06 Task 1
  (tests/build/cursor-visibility.test.ts). Each flip is surgical
  (single line / single bullet, with explicit "back-patched in
  Phase 4 Plan 04-06" citation). Historical commit-description
  lines 40, 89, 109, 110 are LEFT unchanged — they describe what
  the Phase-1-closure commits literally did at the time, not
  forward-looking deferrals.
- .planning/phases/04-harden-clean-up-optional/deferred-items.md
  (correction, BLOCKER 2 resolution):
  Corrected the misdiagnosed entry from commit 6a989e8. The prior
  entry named tests/build/strict-meta-json-validation.test.ts as
  failing on a clean tree — that diagnosis was WRONG (the test is
  8/8 GREEN in isolation). The real root cause is the pre-existing
  04-CONTEXT #9 + #10 parallel-vitest / ffprobe-timeout flake
  family (lands non-deterministically on whichever ffprobe / race
  test loses the worker race; observed instance this session was
  tests/background/webm-remux.test.ts > ffprobe -count_frames,
  which is also 5/5 GREEN in isolation). True clean baseline is
  184/184 GREEN; 188/188 after Plan 04-06's +4 new tests.

Gates run:
- npx tsc --noEmit exit 0.
- npm run build:test exit 0; dist-test/assets/welcome-CMygHJ_J.js
  carries the raw SVG source.
- HEADLESS=1 SKIP_PROD_REBUILD=0 SKIP_LONG_UAT=1 npm run test:uat:
  36/36 UAT assertions GREEN (was 35/35; +A35). A17.8 PASS:
  currentColorStroke=true, canonicalViewBox=true. A35 live-DOM
  probe: svgPresent=true strokeAttr=currentColor
  computedStroke="rgb(250, 247, 241)" (linen-50, the
  --mks-fg-inverse value flowing through the cascade — the
  currentColor strategy WORKS in real Chrome) imgPresent=false.
- All Task 3 acceptance greps PASS: driveA35 count in
  harness-page-driver.ts=5, in harness.test.ts=6; name:'A35'=1;
  getComputedStyle=6; stroke="currentColor" in
  extension-page-harness.ts=4; data:image/svg+xml=0 (grep target
  and comment refs both removed).

# Phase 04 — Deferred Items (out-of-scope discoveries during execution)
Items discovered during plan execution that are NOT caused by the current
plan's changes. Logged per the executor scope-boundary rule; NOT fixed in
the discovering plan.
| Item | Discovered During | Description | Disposition |
|------|-------------------|-------------|-------------|
| Non-deterministic parallel-vitest / ffprobe-timeout flake family (04-CONTEXT.md in-scope items #9 + #10) | Plan 04-06 baseline check (2026-05-22; corrected 2026-05-26 in Plan 04-06 Task 3) | Full `npx vitest run` intermittently produces **183 passed / 1 failed (184 total)** on a clean tree. The "1 failed" lands non-deterministically on whichever ffprobe / parallel-worker race test loses the worker race — observed instances include `tests/background/webm-remux.test.ts > ffprobe -count_frames reports between 905 and 912 frames inclusive` (`Error: Test timed out in 5000ms`). Both `webm-remux.test.ts` (5/5) and `tests/build/strict-meta-json-validation.test.ts` (8/8) pass deterministically when run in isolation (`npm test -- <file> --run`). **CORRECTION**: a prior version of this entry (commit `6a989e8`) named `strict-meta-json-validation.test.ts` as failing on a clean tree — that diagnosis was wrong; that test is GREEN in isolation. The real root cause is the pre-existing **04-CONTEXT #9** (parallel-vitest Tier-1-build-step race; ~1/5 full-suite runs) + **#10** (2 ffprobe/ffmpeg vitest flakes), which are already enumerated as in-scope items in `04-CONTEXT.md`. The true clean baseline is **184/184 GREEN** (188/188 after Plan 04-06 adds 4 new tests). Plan 04-06 Task 2's VITEST GATE LOGIC tolerates a single isolation-passing flake (NOT a hard-coded named test) and FAILS on any reproducible-in-isolation failure or 2+ failures. | Out of scope for Plan 04-06. Routed as "04-CONTEXT #9/#10 parallel-vitest ffprobe flake family" (NOT as "strict-meta-json fails on a clean tree" — that prior diagnosis is wrong). If a `/gsd-debug` is opened, route to the parallel-vitest worker-isolation strategy (the canonical Vitest mitigation is `poolOptions.threads.singleThread:true` for the affected files, OR raising `testTimeout` on the ffprobe `it.skipIf` block). Do NOT fix in Plan 04-06. |
