f44ca3afba wip(01-11): wave-3 partial — A1+A4 attempted, popup-bridge SW state query unreliable
Task 4 of Plan 01-11 attempted A1-A4 wiring. Empirical run reveals an
architectural blocker that needs orchestrator-level decision.

Current state after this commit (SKIP_PROD_REBUILD=1 npx tsx tests/uat/harness.test.ts):
- A0 [PASS]: production bundle hook-leak grep gate (17ms)
- A1 [FAIL]: SW bootstrap → setIdleMode — popup state never transitions
  to '' despite keepalive ping + 3s waitFor. chrome.action.getPopup({})
  from the popup page consistently returns the manifest default
  (chrome-extension://<id>/src/popup/index.html), not the '' that
  setIdleMode's chrome.action.setPopup({popup:''}) should produce.
- A2 [FAIL]: toolbar onClicked — badge never transitions to "REC" after
  page.triggerExtensionAction(extension); 8s timeout. Either the
  toolbar action isn't reaching the SW listener, OR getDisplayMedia's
  picker isn't resolving in headless mode (despite the auto-select flag).
- A3 [FAIL]: offscreen target never appears (correlates with A2 — no
  recording started, no offscreen document spawned).
- A4 [PASS]: trivially passes (offscreen count is 0 → 0, both before
  + after the click). Not a true assertion of behavior; would also pass
  if the whole extension were broken.
- A5-A13: stubbed RED per plan.

Architectural blocker (Rule 4 — needs orchestrator decision):
- Puppeteer 25.0.2 + Chrome 148 + headless cannot reliably keep the MV3
  SW alive long enough OR expose its real chrome.* state to a popup
  page query. The popup-bridge architecture (Task 3 commit dbd977c)
  works for synchronous bridge queries (snapshot, fire-on-startup)
  but does NOT reliably reflect chrome.action.setPopup / setBadgeText
  state changes initiated by the SW.

Three plausible paths forward (need orchestrator pick):

  Option A — Content-script bridge: inject a content script that
    bridges chrome.* queries to a webpage's window.* RPC surface;
    harness uses page.evaluate against the content script instead of
    popup.evaluate. Pros: content scripts have stable lifetime tied to
    the page they're injected into. Cons: content scripts have
    DIFFERENT chrome.* surface (no chrome.action API surface — they
    can't read getBadgeText / getPopup at all). Likely DOESN'T solve
    the underlying problem.

  Option B — Headful with Xvfb on CI: relax the headless requirement;
    accept Xvfb dependency. Per Plan 01-11 RESEARCH §3, RESEARCH
    claimed headless works on Chrome 148 — empirical refutation here.
    Pros: SW lifetime is more stable in headful mode; setPopup
    propagation is reliable. Cons: introduces Xvfb dep that RESEARCH
    explicitly said wasn't needed; CI complication.

  Option C — Shrink harness scope to bridge-able assertions: A0 (grep
    gate), A8 (Bug A onStartup via bridge), A9 (icon sizes via popup
    fetch), A10 (manifest via popup), A13 (zip shape — operator runs
    SAVE_ARCHIVE manually + drops zip to a known path; harness reads
    it). Skip A1-A7, A11, A12 (the ones that require live SW state
    observation through chrome.action API). Pros: ships the
    bug-A-coverage portion of the harness today; keeps Plan 01-09's
    Task 5 operator-checkpoint partly automated. Cons: doesn't retire
    operator entirely; Plan 01-09 stays open on operator-empirical
    A1-A7.

  Option D — Switch to WebDriver BiDi (the Puppeteer 25 alternative
    backend): Puppeteer 25 supports BiDi via {protocol: 'webDriverBiDi'}.
    BiDi may handle extension SW evaluation differently (different
    isolation model). Speculative — no empirical evidence either way.

What landed cleanly:
- Tier-1 hook-leak grep gate (T-1-11-01) GREEN: dist/ has zero
  __mokoshTest / simulateUserStop / getSegmentCount / setCurrentStream
  / setSegmentCountGetter / __mokoshTestQuery / __mokoshKeepalive
  occurrences after npm run build.
- Two-bundle infrastructure (dist/ vs dist-test/) operational.
- Bridge handler in sw-hooks.ts works for snapshot + fire-on-startup
  + handler-types ops (verified by no-hang on keepalivePing call).
- Existing 89-test vitest baseline preserved (no regression from any
  Wave 0/1/2/3 work).

Verification:
- npx tsc --noEmit (src/): exit 0
- npx tsc --noEmit -p tests/uat: exit 0
- npm run build: exit 0; dist/ hook-free
- SKIP_BUILD=1 npx vitest run: 89/89 GREEN
- SKIP_PROD_REBUILD=1 npx tsx tests/uat/harness.test.ts:
  2/14 passed (A0 + A4-trivially), 12 FAIL — non-zero exit as expected.

dbd977c815 feat(01-11): wave-2 — Puppeteer harness scaffolding + A0 GREEN, popup-bridge architecture
Task 3 of Plan 01-11 (Puppeteer UAT harness).

Harness file tree (tests/uat/):
- harness.test.ts: tsx-runnable top-to-bottom harness entry point.
  Runs A0 inline (filesystem grep gate, abort-on-fail T-1-11-01),
  then launches Chrome + opens popup bridge + queries manifest, then
  iterates A1-A13 stubs. Each stub throws "NOT YET IMPLEMENTED —
  Plan 01-11 Task N wires this assertion". Exit code = 0 on full
  pass, 1 otherwise. Final line: "UAT harness: N/14 assertions passed".
- lib/launch.ts: launchHarnessBrowser() — wraps puppeteer.launch with
  enableExtensions:[dist-test/], headless default (HEADLESS=0
  override), --no-sandbox + --auto-select-desktop-capture-source flags.
  Polls browser.extensions() until the extension registers (empirically
  ~100ms but the first call right after launch returns Map(0)).
  Opens both a blank page (for triggerExtensionAction) AND the popup
  page (the bridge surface). Returns { browser, extension, extensionId,
  sw, downloadsDir, page, popup }.
- lib/extension.ts: waitForOffscreenTarget + attachToOffscreen +
  countOffscreenTargets. Offscreen attach uses target.type() ===
  'background_page' + .asPage() (NOT .page() — RESEARCH §4 Pitfall 1).
- lib/sw.ts: chrome.* state queries via the POPUP page handle (NOT
  the WebWorker handle — see architecture note below). getBadgeText,
  getPopup, getManifest, getIconSize, getIsRecording (side-channeled
  through badge text), fireOnStartup (via __mokoshTestQuery bridge),
  sendSyntheticRecordingError, getNotificationSnapshot (via bridge),
  keepalivePing (no-op message to wake SW for ~30s).
- lib/offscreen.ts: getDisplaySurface, simulateUserStop (the
  dispatchEvent('ended') path per RESEARCH §7 BLOCKER — DO NOT REFACTOR
  to track.stop()), getSegmentCount.
- lib/assertions.ts: runAssertion(idx, name, buffers, fn) wrapper —
  records pass/fail/duration; on failure dumps last 30 lines of SW
  + offscreen console buffers to stderr before rethrowing. assertEqual
  / assertMatch / assertTrue / assertGte / waitFor polling helper.
- lib/zip.ts: jszip-based assertArchiveShape + extractEntryToFile for
  assertions 12 + 13.
- README.md: runtime + local-debug + CI semantics + locale gotcha
  + dev-dep size note + assertion catalog table.
- tsconfig.json: per-tree type-check config (mirrors root tsconfig.json
  compiler options but includes the harness tree explicitly).

Architecture refinement (DEVIATION from RESEARCH §1 — Rule 1+3 inline fix):
- RESEARCH §1 sketched `sw.evaluate(() => chrome.action.getBadgeText({}))`
  as the chrome.* query path. Empirical probes during Task 3 execution
  against Puppeteer 25.0.2 + Chrome 148 + --headless=true revealed two
  blockers:
    1. Puppeteer's WebWorker.evaluate runs in an ISOLATED WORLD that
       carries SW globals (clients, registration, ...) but NOT the
       extension's full chrome.* API surface. Object.keys(chrome) inside
       sw.evaluate returns ["loadTimes","csi"] — the public webpage
       chrome, not the extension chrome.
    2. Chrome 148's headless mode aggressively suspends MV3 service
       workers; subsequent swTarget.worker() calls return
       "Protocol error: No target with given id found".
- WORKAROUND: open the popup page (chrome-extension://<id>/src/popup/
  index.html) as a separate Puppeteer Page. The popup has full
  chrome.* access (it's an extension context with same privileges as
  the SW) AND stable Puppeteer lifetime. For SW-globalThis state
  (__mokoshTest in the SW isolate, NOT in the popup), bridge via
  chrome.runtime.sendMessage. The popup sends
  { type: '__mokoshTestQuery', op: 'snapshot' | 'fire-on-startup' |
  'handler-types' }; the SW hook's onMessage handler responds.
- Bridge implementation added to src/test-hooks/sw-hooks.ts — registers
  AFTER the production listeners so it never intercepts production
  messages (__mokoshTest* type is unambiguously test-only). Tier-1
  grep gate (no-test-hooks-in-prod-bundle.test.ts) continues to enforce
  ZERO __mokoshTest occurrences in dist/ — the bridge handler is
  tree-shaken alongside the rest of the hook module via the
  __MOKOSH_UAT__ gate.

Other configuration changes:
- vitest.config.ts: exclude tests/uat/** from vitest discovery. The
  Puppeteer harness is invoked via `npm run test:uat` (not vitest);
  running it under vitest would try to launch real Chrome inside a
  vitest worker. The .test.ts suffix is retained for editor +
  naming-convention consistency with the rest of the tree.

Verification:
- npx tsc --noEmit (src/): exit 0
- npx tsc --noEmit -p tests/uat: exit 0
- npm run build: exit 0
- grep -rln '__mokoshTest|simulateUserStop|getSegmentCount|setCurrentStream|setSegmentCountGetter|__mokoshTestQuery|__mokoshKeepalive' dist/: ZERO matches
- npm run build:test: exit 0; dist-test/ populated with the new bridge code
- SKIP_BUILD=1 npx vitest run: 89/89 GREEN
- SKIP_PROD_REBUILD=1 npx tsx tests/uat/harness.test.ts:
  → A0 [PASS]: production bundle has no test-hook leaks (19ms)
  → Browser launches; popup opens; manifest read succeeds
  → A1-A13 [FAIL]: NOT YET IMPLEMENTED — Plan 01-11 Task N wires this
  → "UAT harness: 1/14 assertions passed, 13 failed (first failure: A1)"
  → Exit code: 1 (expected — 13 RED stubs intentional)

cb1a729962 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.
