Mark b5181012a8 feat(03-02): Task 1 — assertA30 page-side orchestrator (5 event triggers + SAVE)
- Add assertA30 dispatching 5 synthetic browser events on the harness page:
  click (#probe-submit), input (#probe-email),
  navigation (history.pushState #a30-probe), js_error (window.dispatchEvent
  ErrorEvent), network_error (fetch https://example.com/<404-path>).
- Module-local timing/url constants: A30_SAVE_ARCHIVE_TIMEOUT_MS=15s,
  A30_SEGMENT_SETTLE_MS=11s, A30_TRIGGER_SETTLE_MS=500ms,
  A30_404_PROBE_URL (RFC 2606 reserved example.com).
- Wire assertA30 into declare global Window.__mokoshHarness interface +
  window.__mokoshHarness object literal (preserves assertA29 from Plan 03-01).
- Update statusEl banner A29 -> A30 and closing console.log to append
  "Plan 03-02: A30".
- A30 rides production listeners at src/content/index.ts:60-237 + existing
  setupFreshRecording / sendMessageWithTimeout helpers — Tier-1
  FORBIDDEN_HOOK_STRINGS inventory unchanged at 12.

Mokosh UAT harness (Plan 01-11)

Puppeteer-driven Node script that runs 14 assertions end-to-end against a real Chrome instance loaded with the Mokosh extension. Replaces Plan 01-09 Task 5's operator-empirical functional verification (the operator retains only step 1 — build — and step 14 — brand/design acceptance).

Quick start

npm run test:uat

This builds dist-test/ (the hook-enabled bundle) and runs the harness. Exit 0 means all 14 assertions passed. Final line: UAT harness: 14/14 assertions passed.

Local-debug mode

HEADLESS=0 npm run test:uat

Opens a real Chrome window so you can watch the picker auto-accept, the badge transitions, the popup appear, etc.

Developer iteration tricks

# Skip the production build inside assertion 0 (uses existing dist/):
SKIP_PROD_REBUILD=1 npm run test:uat

# Run the harness against an existing dist-test/ (skip npm run build:test):
npx tsx tests/uat/harness.test.ts

Failure isolation

Single browser, serial assertions, bail on first failure for setup- dependent assertions (assertion 0 abort means refusing to launch a potentially-leaky bundle). Per-assertion bail keeps the diagnostic output unambiguous — see RESEARCH §5 + Plan 01-11 open-question resolution 4.

On failure, the harness dumps the last 30 lines of SW console + last 30 lines of offscreen console (captured live during the run) to stderr BEFORE rethrowing — gives you contextual triage without needing to re- run with debug logging.

Known gotchas

Locale-specific picker auto-accept

The --auto-select-desktop-capture-source=Entire screen Chrome flag auto-accepts the screen-share picker. The string "Entire screen" is en_US-specific. If your Chrome is set to a non-English locale, the picker option label will differ and the auto-accept will silently fail (picker stays open; assertion 2 times out).

Fallback: switch your Chrome user-data-dir's locale to en_US for harness runs, OR adjust the launch arg in tests/uat/lib/launch.ts to match your locale's equivalent string.

dev-dep Chromium binary size

puppeteer pulls a ~150 MB Chromium binary at npm install time. CI must accept this. Production npm install --omit=dev skips it cleanly.

Xvfb is NOT required

Per Plan 01-11 RESEARCH §3 empirical probes against Chrome 148, the --headless=new mode handles screen capture without Xvfb on Linux CI runners. If a future Chrome regresses this, Xvfb :99 & DISPLAY=:99 npm run test:uat is the fallback.

CI runner screen-capture concern

The 35s recording assertion (A11) captures whatever is on screen during that window. CI MUST run the harness in an isolated container with no concurrent workload — see T-1-11-02 in Plan 01-11's threat model.

Real Chrome download (assertion 5 → A12)

The harness configures per-page download behavior via CDP to a fresh os.tmpdir()/mokosh-uat-downloads-* directory; downloads are NOT written to your real ~/Downloads. The temp directory is deleted by OS tmpdir GC.
