wip(01-11): prototype — A6 via test-page+bridge+synthetic-stream PASSES
Plan 01-11 orchestrator commissioned a research+prototype investigation
into whether full MV3 UAT automation is feasible with the architecture:
extension-internal test page + chrome.runtime.sendMessage bridge +
synthetic MediaStream (canvas-captureStream + getSettings override).
EMPIRICAL VERDICT: feasible BUT plan 01-11 needs architectural revision.
Architectural findings (with proof):
1. DYNAMIC IMPORT BLOCKED IN MV3 SW. Top-of-module
`await import('../test-hooks/sw-hooks')` in src/background/index.ts
silently kills the SW (chunk loads, await never resolves, no
production listeners register, no console output). This is by design
per Chromium docs (es_modules.md) + w3c/webextensions#212. The Plan
01-11 RESEARCH §6 architecture was wrong for the SW side.
Workaround in this prototype: REMOVE the SW-side gated dynamic
import. SW-side test hooks need a different design (see verdict).
2. OFFSCREEN-SIDE DYNAMIC IMPORT WORKS. Offscreen is a DOM document,
not a SW, so top-level await + dynamic import behave normally. The
offscreen-hooks.ts gated import succeeds; installFakeDisplayMedia is
installed eagerly at module load.
3. EXTENSION-INTERNAL PAGE HAS FULL chrome.* SURFACE. Reachable via
chrome-extension://<id>/tests/uat/prototype/extension-page-harness.html
(added as rollup input in vite.test.config.ts). The page can call
chrome.action.getBadgeText, chrome.action.getPopup, chrome.offscreen
.createDocument, chrome.notifications.getAll, chrome.runtime
.sendMessage — everything needed for A6.
4. NO 'tabs' PERMISSION → tab.url IS UNDEFINED. Production
startVideoCapture's `chrome.tabs.query({active:true})` check
(`if (!tab.id || !tab.url) throw`) fails because the manifest lacks
the 'tabs' permission. Prototype workaround: bypass startVideoCapture
by sending START_RECORDING directly to offscreen. The Bug B
contract being tested is independent of how recording starts; it
only depends on the RECORDING_ERROR routing path.
5. SYNTHETIC MEDIASTREAM WORKS. installFakeDisplayMedia builds a
canvas-captureStream MediaStream + monkey-patches the video track's
getSettings() to report displaySurface: 'monitor'. Production code's
post-grant validation passes. getDisplayMedia returns the synthetic
stream immediately — no picker, no headless flakiness.
A6 prototype result (with Bug B fix in place — current HEAD state):
[PASS] SETUP: badge becomes REC after start
[PASS] A6.1: badge text is '' (NOT 'ERR') after user-stop
[PASS] A6.2: popup is '' (NOT manifest default) after user-stop
[PASS] A6.3: NO recovery notification fired (count delta === 0)
[PASS] A6.4: isRecording=false (via badge proxy)
A6 prototype result (with Bug B fix rewound to `if (false)`):
[PASS] SETUP: badge becomes REC after start
[FAIL] A6.1: badge text is '' (got "ERR")
[FAIL] A6.2: popup is '' (got chrome-extension://.../popup/index.html)
[FAIL] A6.3: notif delta = 0 (got 1)
[PASS] A6.4: isRecording=false ← false-positive (badge='ERR' not 'REC')
The Bug B regression rewind cycle proves the harness CAN catch regression:
4/5 checks turn RED on rewind, 5/5 turn GREEN with the fix restored.
Files in this commit:
- tests/uat/prototype/extension-page-harness.{html,ts} — the harness
page (chrome-extension URL, exposes window.__mokoshHarness.assertA6)
- tests/uat/prototype/a6.test.ts — Puppeteer driver (~270 lines)
- tests/uat/prototype/probe_*.mjs — diagnostic probes used to isolate
the SW dynamic-import blocker (probe_sw.mjs is the key one)
- src/test-hooks/offscreen-hooks.ts — added installFakeDisplayMedia +
dispatchEndedOnTrack + __mokoshOffscreenQuery bridge handler + auto-
install at module load
- vite.test.config.ts — added prototype harness page as rollup input;
added modulePreload.polyfill=false (red herring; harmless)
- src/background/index.ts — removed the broken SW-side gated dynamic
import (this is the BLOCKER unblocker — production 01-11 plan needs
to redesign SW-side test hooks before re-spawning)
Bundle hygiene: prototype runs against dist-test/; production dist/
remains hook-free (Tier-1 grep gate still GREEN, verified via
no-test-hooks-in-prod-bundle.test.ts in the unit test suite).
Vitest baseline: 89/89 GREEN preserved.
Runtime: ~7 seconds end-to-end (launch Chrome + open page + ensure
offscreen + start recording + dispatch ended + settle + assert).
See: research return for VERDICT + recommended next step.

feat(01-11): wave-1 — gated test hooks for SW + offscreen, dist/ stays hook-free
Task 2 of Plan 01-11 (Puppeteer UAT harness).
Test hook surface:
- src/test-hooks/types.ts: canonical MokoshTestSurface — handlers
(onClicked, onStartup, notificationOnClicked), notificationCount,
lastNotificationOptions<true>, notificationIds, getCurrentStream,
getSegmentCount. globalThis.__mokoshTest ambient declaration.
- src/test-hooks/sw-hooks.ts: SW-side hook. Monkey-patches addListener
on chrome.action.onClicked / chrome.runtime.onStartup / chrome
.notifications.onClicked to capture handler refs while chaining to
the original. Wraps chrome.notifications.create across all four
overload shapes (id+options+cb, options+cb, id+options→Promise,
options→Promise) to increment notificationCount, save
lastNotificationOptions, push resolved id into notificationIds.
- src/test-hooks/offscreen-hooks.ts: offscreen-side hook. Exports
setCurrentStream + setSegmentCountGetter; the recorder calls both
inside startRecording after the mediaStream + segments assignments.
getCurrentStream getter closes over the cell so the harness reads
the live MediaStream for displaySurface inspection + 'ended'
dispatch (Bug B BLOCKER per RESEARCH §7).
- tests/uat/lib/test-hook-contract.d.ts: manual harness-side mirror of
MokoshTestSurface (decoupled from src/ to keep tests/ import-clean
per RESEARCH §11 resolution 5; drift risk documented inline).
Production-side wires (gated by __MOKOSH_UAT__ token):
- src/background/index.ts top-of-module: `if (__MOKOSH_UAT__) { await
import('../test-hooks/sw-hooks'); }`. MUST run before any chrome.*
addListener call below — top-of-module placement satisfies this.
- src/offscreen/recorder.ts top-of-module: symmetric gated dynamic
import + module-scoped testHooks reference.
- src/offscreen/recorder.ts inside startRecording (after mediaStream
assignment): `if (__MOKOSH_UAT__) { testHooks?.setCurrentStream(stream);
testHooks?.setSegmentCountGetter(() => segments.length); }`
- src/offscreen/recorder.ts inside onUserStoppedSharing (after
mediaStream = null): `if (__MOKOSH_UAT__) { testHooks?.setCurrentStream(null); }`
— T-1-11-05 (Repudiation: stale stream ref) mitigation.
Build-time token wiring:
- vite.config.ts: declares `define: { __MOKOSH_UAT__: 'false' }` (prod
default) + bumps `build.target: 'es2022'` so the top-level await in
the gated dynamic imports compiles (MDN: Chrome 89 / Edge 89 /
Firefox 89 / Safari 15 support TLA; MV3 floor Chrome 88 is
effectively Chrome 89+ in field — comfortably inside the envelope).
- vite.test.config.ts: overrides `define: { __MOKOSH_UAT__: 'true' }`
so the test bundle has the hooks active.
- vitest.config.ts: declares `define: { __MOKOSH_UAT__: 'false' }` for
vitest's own source-loading runs. CRITICAL — without this, vitest
would throw `ReferenceError: __MOKOSH_UAT__ is not defined` when
loading src/background/index.ts; OR if we'd used `import.meta.env.MODE
=== 'test'` (RESEARCH §6's initial guidance), vitest's default
MODE='test' would have ACTIVATED the hooks under unit tests +
clobbered every existing vi.fn() chrome.notifications.create mock.
The dedicated `__MOKOSH_UAT__` token sidesteps both failure modes
cleanly — a refinement on RESEARCH §6 documented in the comment
preambles of all three configs.
- globals.d.ts: declares `__MOKOSH_UAT__: boolean` ambient so
`npx tsc --noEmit` passes without per-file annotations.
- tsconfig.json: include adds `globals.d.ts`.
Notification options generic refinement:
- chrome.notifications.NotificationOptions is declared with a
`<true | false>` generic distinguishing "create" (all required —
true) from "update" (all optional — false). Plan 01-11's production
code always uses the create shape; types.ts + sw-hooks.ts pin to
`NotificationOptions<true>` so the harness reads iconUrl etc. as
definitely-present.
Verification:
- npx tsc --noEmit: exit 0
- npm run build: exit 0
- grep -rln '__mokoshTest\|simulateUserStop\|getSegmentCount\|setCurrentStream\|setSegmentCountGetter' dist/:
ZERO matches (Tier-1 gate stays GREEN)
- npm run build:test: exit 0; dist-test/ emits separate sw-hooks-*.js
+ offscreen-hooks-*.js chunks (the gated dynamic imports survive
tree-shaking when __MOKOSH_UAT__ === true)
- grep -rln '__mokoshTest' dist-test/: 2 matches
(assets/sw-hooks-*.js + assets/offscreen-hooks-*.js)
- SKIP_BUILD=1 npx vitest run: 89/89 GREEN
(83 baseline + 6 Tier-1 hook-leak surfaces)
- sw-bundle-import.test.ts: GREEN (the gated dynamic import does not
break production module init — the `if (false)` branch is never
reachable so the await + import are dead code in dist/)
In-flight bugs auto-fixed (Rule 1 + Rule 3):
- Rule 3: original RESEARCH §6 plan called for `import.meta.env.MODE
=== 'test'` as the gate; switched to `__MOKOSH_UAT__` define-token
after observing vitest contamination (vitest defaults MODE='test'
→ hooks activated under unit tests → 8 existing tests broke with
"Cannot read properties of undefined (reading 'calls')" because the
hook wrapper replaced vi.fn() mocks). Documented in the comment
preambles of all three configs as a refinement on RESEARCH §6.
- Rule 3: esbuild rejected TLA against the default ES2020 target;
bumped to es2022 (Chrome 89+ supports TLA per MDN — inside MV3
envelope). Recorded in vite.config.ts preamble.

chore(01-11): wave-0 — install puppeteer + tsx, add vite.test.config + Tier-1 hook-leak grep gate
Task 1 of Plan 01-11 (Puppeteer UAT harness). - npm install --save-dev puppeteer@^25.0.2 tsx@^4 @types/node resolved: puppeteer@25.x, tsx@4.22.1, @types/node@25.8.0 pulls ~150MB Chromium binary at install time (T-1-11-03 — accepted, package-lock pins resolved hashes via @puppeteer/browsers). - package.json scripts: add build:test + test:uat (per RESEARCH §10 two-bundle orchestration); existing dev/build/preview/test untouched. - vite.test.config.ts: extends ./vite.config.ts via mergeConfig with mode:'test' + build.outDir:'dist-test' + emptyOutDir:true. Verified npm run build:test produces dist-test/ in 7.93s; npm run build keeps producing dist/ in 7.67s (no clobber). - tsconfig.json `include: ["src"]` already covers src/test-hooks/**/* via wildcard — no edit needed. - tests/background/no-test-hooks-in-prod-bundle.test.ts: Tier-1 gate mirroring sw-bundle-import.test.ts's execFile pattern. Greps the BUILT dist/ tree for 5 forbidden hook surfaces (one `it` per surface for granular failure isolation): __mokoshTest, simulateUserStop, getSegmentCount, setCurrentStream, setSegmentCountGetter. All 5 surfaces absent today (RED-then-GREEN polarity inverted — the gate is GREEN now and MUST stay GREEN after Task 2 lands the hooks). SKIP_BUILD=1 escape hatch for developer iteration. - .gitignore: add dist-test/ (no point versioning generated test bundle). Verification: - npx tsc --noEmit: exit 0 - npm run build: exit 0; dist/ populated (375.37 kB SW chunk) - npm run build:test: exit 0; dist-test/ populated (identical chunk sizes — the gated dynamic imports do not land until Task 2; this commit only proves the two-bundle plumbing) - SKIP_BUILD=1 npx vitest run tests/background/no-test-hooks-in-prod-bundle.test.ts: 6/6 GREEN (1 build-sanity + 5 forbidden-surface) - SKIP_BUILD=1 npx vitest run (full suite): 89/89 GREEN (83 baseline + 6 new Tier-1 surfaces = 89) Working-tree cleanup: a stale 5.4 MB tests/fixtures/last_30sec.webm (unrelated operator smoke regen present at session spawn) was stashed before running the baseline — it caused the webm-playback test to time out at 5s. After stashing back to HEAD's 1.9 MB fixture, baseline passes cleanly. Not committing the fixture restoration here (pre-existing working-tree state, not part of Task 1).
