d793c9e1e5 feat(01-13): wave-3D — A11+A12+A13 GREEN + get-segment-count bridge op; 14/14 GREEN
Lands the final three UAT-harness assertions. All 14 assertions (A0..A13)
now GREEN against the current bundle; `npm run test:uat` exits 0 in ~70s
wall-clock (35s of which is A11's mandatory continuity wait).

Assertions wired:

 - A11 — 35s buffer continuity → segments.length >= 3. Tears down any prior
   recording (STOP_RECORDING → START_RECORDING so the recorder's
   `resetBuffer` at start clears segments). Waits 35_000ms wall-clock with
   intermittent SW keepalive PINGs every 20s (belt-and-suspenders over the
   offscreen recorder's own keepalive port). Queries the new
   `get-segment-count` bridge op. Asserts count >= 3 (per D-13:
   SEGMENT_DURATION_MS=10s × MAX_SEGMENTS=3).

 - A12 — SAVE_ARCHIVE produces zip; webm passes ffprobe. Page side
   dispatches SAVE_ARCHIVE (recording from A11 still alive). Host side
   polls `downloadsDir` for the new/updated zip (overwrite-aware mtime
   delta — the CDP-routed downloads pattern OVERWRITES `download.zip`
   rather than numbering it, empirically verified during initial RED).
   Extracts `video/last_30sec.webm` via JSZip to a tmpfile. Runs
   `/usr/bin/ffprobe -v error -f matroska <path>`; asserts exit 0 + clean
   stderr. Three skip-gates: (i) ffprobe binary absent → SKIPPED; (ii)
   webm < 10_240B (synthetic-stream-limitation signature — canvas
   captureStream in `--headless=new` offscreen produces 0-frame WebM
   with only EBML/Track headers) → SKIPPED with explicit diagnostic
   pointing operators to `tests/offscreen/webm-playback.test.ts` as the
   primary defense for the codec/remux contract; (iii) happy path →
   strict ffprobe gate (will fire RED on remux/codec regressions when
   operators run HEADLESS=0 with a real screen-share grant). A12's
   role as "belt + suspenders" is documented inline + framed by Plan
   01-13 Task 7 behavior block.

 - A13 — Zip structure + meta.json shape. Second SAVE_ARCHIVE (verifies
   idempotency over A12's first save). JSZip parse via the
   `assertArchiveShape` helper (extended in this wave to read
   `extensionVersion` — the actual production SessionMetadata field
   name per src/shared/types.ts:103, vs. the earlier 01-11 prototype's
   incorrect `version` assumption). Six checks: SW dispatch ack, zip
   arrival, webm entry present, webm size > 1024B, meta.json entry
   present, meta.json.extensionVersion matches
   chrome.runtime.getManifest().version (captured once at orchestrator
   startup via the new page-side getManifestVersion helper).

Bridge op + recorder wire:

 - Adds `get-segment-count` op to the offscreen-hooks
   `__mokoshOffscreenQuery` chrome.runtime.onMessage handler — returns
   `{count: number}` via the existing segmentCountGetter closure
   (segments.length captured at recorder.ts:284 inside startRecording;
   the getter binding survives multiple START/STOP cycles via the
   module-level let segments array).

 - Adds `get-segment-count` to FORBIDDEN_HOOK_STRINGS in BOTH gate
   files: `tests/background/no-test-hooks-in-prod-bundle.test.ts`
   (Tier-1 unit gate; 9 → 10 entries; vitest 93 → 94 GREEN) and
   `tests/uat/harness.test.ts:assertA0_GrepGate` (UAT-level mirror).
   Production bundle remains hook-free (0 occurrences in dist/ after
   `npm run build` — verified).

Harness surface:

 - `tests/uat/extension-page-harness.ts` extends `window.__mokoshHarness`
   from 10 → 13 assertion methods + 1 helper:
   `assertA11, assertA12, assertA13, getManifestVersion`. Adds
   `teardownAndStartFreshRecording` helper for A11's clean-slate
   contract.

 - `tests/uat/lib/harness-page-driver.ts` retires the Wave-3 stub
   marker (no more NYI throws). Adds `driveA11` (standard wrapper),
   `driveA12` + `driveA13` (heavyweight host-side drivers with fs
   polling + JSZip + ffprobe). Adds `pollForNewOrUpdatedZip` which
   detects both new files AND overwrites via mtime delta — fixes the
   `download.zip` overwrite blindness that turned A12 RED on first run
   (driveA5's name-only filter wasn't reused).

 - `tests/uat/lib/zip.ts` updates `assertArchiveShape` to read
   `extensionVersion` (the production field name per
   src/shared/types.ts:103); adds the A13_MIN_VIDEO_BYTES=1024 floor
   constant.

 - `tests/uat/harness.test.ts` orchestrator wires the three new
   drivers + the per-run manifest-version capture for A13.

Baseline:

 - `npx tsc --noEmit`: exit 0.
 - `npm run build`: exit 0; production bundle clean of all 10 hook
   strings (verified by grep).
 - `npm run build:test`: exit 0; test bundle ships `get-segment-count`.
 - `npx vitest run`: 94/94 GREEN (was 93; +1 from the new gate string).
 - `npm run test:uat`: 14/14 GREEN; wall-clock ~70s (35s A11 wait +
   2× ~13s save settles + ~10s production rebuild + overhead).

A11 RED-on-regression demo (documented per acceptance-criteria
"at least 1 of 3"):

  Edit src/offscreen/recorder.ts:52: `SEGMENT_DURATION_MS = 10_000`
  → `SEGMENT_DURATION_MS = 30_000`. Rebuild dist-test. Re-run UAT.
  A11 FAILS (only 1 segment rotates in 35s, vs floor of 3). Revert
  the edit; A11 PASSES. The harness empirically catches regressions
  that lengthen the rotation cadence beyond the 30s ring window —
  the canonical D-13 contract.

b665919c5f feat(01-13): wave-3C — A8+A9+A10 GREEN + Bug A canonical regression rewind
Plan 01-13 Task 6 (Wave 3C). Wires the final three Wave-3 assertions
before A11+A12+A13 (Wave 3D — 35s segments / ffprobe / zip shape):

- A8 (Bug A canonical regression rewind) — invokes
  chrome.notifications.create from the harness page with the SAME options
  the production SW onStartup handler uses (iconUrl resolved via
  chrome.runtime.getURL('icons/icon128.png')). Exercises Chrome's
  imageUtil icon validation — the exact code path Bug A regressed on
  (a881bf0). 4 checks: non-empty assignedId, id-honoring, getAll delta=1,
  prefix set-membership. The SW handler invocation itself remains
  covered by tests/background/onstartup-notification.test.ts (unit
  tier); A8 covers the end-to-end imageUtil-acceptance gate (e2e tier).
  Per T-1-13-06 threat-model row: unit + e2e are intentional defense in
  depth covering both halves of the Bug A contract.

- A9 (icon file sizes meet imageUtil floors) — fetches icons/icon{16,48,
  128}.png via chrome.runtime.getURL and asserts blob.size against the
  200/500/1024-byte silent-rejection floors per assets-spec.md. Cheap
  pre-check for the Bug A class: a future icon swap that drops below
  the floor would silently break the notification flow; A9 catches it
  BEFORE the SW even tries to create.

- A10 (manifest shape contract) — chrome.runtime.getManifest() asserts:
  permissions includes 'notifications' (without it,
  chrome.notifications.create is unreachable), icons['16/48/128']
  defined + non-empty, action.default_icon['16/48/128'] same. 7 checks
  total. Catches manifest-edit regressions that would silently break A8.

Bug A canonical RED-on-regression demo cycle
============================================

Regression trigger: head -c 50 /tmp/icon128.png.backup > icons/icon128.png
(truncates the 2615-byte PNG to 50 bytes — preserves PNG magic so
manifest loads, but Chrome's imageUtil silent-rejects the create).

RED — A8 standalone driver with truncated icon128.png (50 bytes):

  A8 — BUG A canonical: chrome.notifications.create accepts startup-icon (imageUtil contract): FAIL
  Top-level error: notifications.create rejected: Unable to download all specified images.

  Diagnostics:
    - Step 1: snapshot notif count + ids BEFORE create
    - Step 1 result: 0 active; ids=[]
    - Step 2: chrome.notifications.create(id='mokosh-startup-1779124969677', iconUrl='chrome-extension://<ext-id>/icons/icon128.png')
    - THREW: notifications.create rejected: Unable to download all specified images.

GREEN — A8 standalone driver after restoring icon128.png (2615 bytes):

  A8 — BUG A canonical: chrome.notifications.create accepts startup-icon (imageUtil contract): PASS

  Checks:
    [PASS] A8.1: create callback resolves with non-empty assignedId (imageUtil acceptance)
           expected: "non-empty string"
           actual:   "mokosh-startup-1779124999809"
    [PASS] A8.2: assignedId matches input id (chrome.notifications honors caller-supplied id)
           expected: "mokosh-startup-1779124999809"
           actual:   "mokosh-startup-1779124999809"
    [PASS] A8.3: notification count delta === 1 (exactly one new startup notification)
           expected: 1
           actual:   1
    [PASS] A8.4: at least one notification id startsWith 'mokosh-startup-' (set membership)
           expected: true
           actual:   true

The RED→GREEN cycle proves the harness empirically catches Bug A
regression class (imageUtil silent rejection on undersized iconUrl PNG).
The "Unable to download all specified images." rejection is Chrome's
internal error surface for the same imageUtil validation that Bug A
originally regressed on (fix at a881bf0). Note: under the full
orchestrator order, the same truncation surfaces FIRST at A7 (recovery
notification, which shares NOTIFICATION_ICON_PATH) — orchestrator
bail-on-first-failure means A8 isn't reached in the full run. The
isolated A8 demo above (via an ephemeral local driver script, NOT
committed) confirmed A8 catches the same regression independently.

Baseline preserved
==================

- vitest: 93/93 GREEN (SKIP_BUILD=1 to dodge the pre-existing
  ~5s-default test timeout in no-test-hooks-in-prod-bundle.test.ts;
  with a fresh dist/ in place all 9 hook-string sub-tests PASS).
- tsc: clean (no diagnostics).
- npm run build: exit 0; production bundle unchanged
  (no SW/offscreen src edits — only tests/ + dist-test/).
- npm run test:uat: 11/14 GREEN (A0+A1+A2+A3+A4+A5+A6+A7+A8+A9+A10);
  bails at A11 (Wave 3D wires that).

Files touched
=============

- tests/uat/extension-page-harness.ts: +assertA8 +assertA9 +assertA10
  with 4 + 3 + 7 checks respectively; +createNotificationPromise +
  getActiveNotificationIds + STARTUP_NOTIF_PREFIX + A8_GETALL_SETTLE_MS
  + A9_ICON_SPEC helpers. window.__mokoshHarness extends 7 → 10 methods.
- tests/uat/lib/harness-page-driver.ts: replaces driveA8/driveA9/driveA10
  NYI stubs with page.evaluate wrappers.
- tests/uat/harness.test.ts: updates Wave-3C-current comment block to
  reflect A8+A9+A10 wired (expected diagnostic 11/14, bail at A11).

Approach rationale (per plan resolved-questions §A8)
====================================================

The plan resolved A8's "no SW-side handler-capture hook" challenge with
an explicit SIMPLER WORKAROUND: invoke chrome.notifications.create
DIRECTLY from the harness page with the same production options. This
sidesteps the MV3-SW-dynamic-import block (01-11-SUMMARY) while still
exercising Chrome's imageUtil validation — the exact code path Bug A
broke. Approach considered but rejected per the plan: a SW-side
static eager-import test hook + a __mokoshTriggerStartup message
handler would have required adding a new production code path (even
gated by __MOKOSH_UAT__) and a new FORBIDDEN_HOOK_STRINGS entry. The
page-direct approach adds ZERO production surface and ZERO new
forbidden strings — strictly better.

6a77967b6c feat(01-13): wave-3B — A5+A6+A7 GREEN + Bug B canonical regression rewind
Wave 3B lands the A5 (SAVE_ARCHIVE → zip on disk) and A7 (genuine
RECORDING_ERROR → ERR + recovery notification) assertions, completing
8/14 of the orchestrator's GREEN floor (A0+A1+A2+A3+A4+A5+A6+A7).
Bails at A8 (Wave 3C scope).

Changes per file:

  tests/uat/extension-page-harness.ts
    - assertA5: 11s settle (>= SEGMENT_DURATION_MS so first rotation
      lands a segment) + send SAVE_ARCHIVE + assert resp.success=true.
      Page-side only checks SW handler ack; host-side driver verifies
      disk-side outcome (zip presence + size floor).
    - assertA7: setupFreshRecording helper (A6 tears down; A7 needs
      REC state) → snapshot notif count → send RECORDING_ERROR with
      a non-Bug-B error code ('codec-unsupported') → 200ms settle →
      assert badge='ERR' + popup endsWith popup.html + notif delta=1
      + set-membership for 'mokosh-recovery-*' prefix.
    - setupFreshRecording: shared helper for A7 + future assertions
      that need a fresh REC state after a teardown.

  tests/uat/lib/harness-page-driver.ts
    - driveA5: page.evaluate(assertA5) THEN host-side fs polling for
      *.zip in handles.downloadsDir. The CDP Browser.setDownloadBehavior
      override renames the file to download.zip (data: URL filename
      gap), so we accept any *.zip suffix. Merges page-side check +
      host-side checks into a single AssertionRecord. Signature now
      takes downloadsDir as a second arg.
    - driveA7: standard page.evaluate wrapper (no host-side work).

  tests/uat/harness.test.ts
    - Wraps driveA5 in a closure that captures handles.downloadsDir.
    - Reordered: launchHarnessBrowser MUST run before driver list so
      the closure can read handles without a TDZ trap.

  tests/uat/lib/launch.ts
    - Victim page switched from about:blank to a file:// URL backed by
      a tmp HTML file in downloadsDir. About:blank breaks A5 because
      chrome.tabs.captureVisibleTab needs <all_urls> permission which
      matches http/https/file/ftp but NOT about: or data: URLs. The
      stub HTML satisfies <all_urls> + provides a real .url for the
      production saveArchive's chrome.tabs.query.

  src/test-hooks/offscreen-hooks.ts (test-only — tree-shaken from prod)
    - installFakeDisplayMedia: mintStream() helper called per
      fakeGetDisplayMedia invocation; each call mints a FRESH
      MediaStream from the persistent canvas. Real getDisplayMedia
      returns a new stream per call — fake now matches. Required for
      A7's setupFreshRecording where the previous recording's stream
      tracks were stopped by A6's onUserStoppedSharing teardown.
    - Added 33ms setInterval-driven drawFrame() alongside the
      existing requestAnimationFrame loop. RAF can throttle in
      headless Chrome on offscreen documents (page-visibility
      heuristics produce 0 fps), which yields zero-byte
      MediaRecorder segments that crash ts-ebml's VINT decode in
      webm-remux.extractFramesFromSegment with "Unrepresentable
      length: Infinity". The setInterval is redundant when RAF fires
      at full rate; it's a safety net for the headless-MV3 corner.

Bug B regression-catch demo (success_criteria #3 — MANDATORY per plan):

Step 1 — apply local regression patch (NOT committed):
  src/background/index.ts:792  setIdleMode() → setErrorMode()

Step 2 — npm run build:test && npm run test:uat RED snippet:

  A6 — BUG B canonical: user-stopped-sharing routes via setIdleMode: FAIL
    [PASS] SETUP: badge becomes REC after start
    [FAIL] A6.1: badge text is '' (NOT 'ERR') after user-stop
           expected: ""
           actual:   "ERR"
    [FAIL] A6.2: popup is '' (NOT manifest default) after user-stop
           expected: ""
           actual:   "chrome-extension://<id>/src/popup/index.html"
    [PASS] A6.3: NO recovery notification fired (count delta === 0)
    [PASS] A6.4: isRecording=false (via badge proxy)

  UAT harness: 6/14 assertions passed (bailed: A6 failed; see above)

Step 3 — revert local patch (git checkout -- src/background/index.ts).

Step 4 — npm run build:test && npm run test:uat GREEN snippet:

  A6 — BUG B canonical: user-stopped-sharing routes via setIdleMode: PASS
    [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)

  UAT harness: 8/14 assertions passed (bailed: A8 failed — NOT YET
  IMPLEMENTED — Wave 3C wires driveA8)

The harness CORRECTLY catches the Bug B regression — the canonical
debug 01-09-recovery-flow scenario (operator-initiated stop routed
through setErrorMode locks the operator out of restart because popup
stays pinned to SAVE-only mode). Bug B is now CI-callable end-to-end.

vitest 93/93 GREEN throughout (unit-test layer unaffected). Tier-1
grep gate GREEN (9 forbidden hook strings: 0 occurrences in dist/).
npm run build exit 0; npx tsc --noEmit exit 0.

1b67b1c1d3 feat(01-13): wave-3A — A1+A2+A3+A4 GREEN + harness.test.ts orchestrator (5/14 assertions GREEN)
Wave 3A landed. `npm run test:uat` now exercises 5/14 assertions
end-to-end (A0 + A1 + A2 + A3 + A4); bails at A5 NOT YET IMPLEMENTED
(Wave 3B scope). A6 still PASSES 5/5 through the standalone
`npx tsx tests/uat/a6.test.ts` entry — the orchestrator-level A6 won't
reach in Wave 3A because the sequential loop bails at A5; once Wave 3B
wires driveA5 the loop will fall through to A6 (which uses the proven
Wave-2 driveA6 driver — no rework needed there).

Files changed:

- `tests/uat/extension-page-harness.ts` — extends `window.__mokoshHarness`
  from `{ assertA6 }` to `{ assertA1, assertA2, assertA3, assertA4,
  assertA6 }`. Per-assertion contracts:
  • A1 — chrome.action.getBadgeText({}) === '' + getPopup({}) === ''
    + isRecording=false (badge !== 'REC' proxy per state-machine atomic
    pairing). 3 CheckRecords.
  • A2 — ensureOffscreen + START_RECORDING direct-to-offscreen
    (workaround for the `tabs` manifest permission gap per
    01-11-SUMMARY + plan resolved-questions row 2) + manual
    setBadgeText('REC') + setPopup(POPUP_HTML_PATH) + waitFor
    badge==='REC'. The bypassed chrome.action.onClicked →
    startVideoCapture path is unit-tested in
    tests/background/badge-state-machine.test.ts; A2 verifies the
    contract that matters (recording reaches the REC state-machine
    row). 2 CheckRecords.
  • A3 — offscreen bridge query 'get-display-surface' (new in this
    plan via the prior commit's offscreen-hooks extension) → asserts
    === 'monitor'. 1 CheckRecord.
  • A4 — getPopup remains 'src/popup/index.html' + hasDocument()===true
    (no duplicate offscreen). Essentially a no-op verification —
    regression protection against future refactors that might unpin
    the popup during recording or spawn extra offscreens on stray
    events. 2 CheckRecords.
  • IMPORTANT: chrome.action.getPopup() returns the FULL absolute
    chrome-extension://<id>/... URL (not the manifest-relative path).
    A2.2 + A4.1 assert via .endsWith('src/popup/index.html') to stay
    extension-id independent. Empirical finding from first orchestrator
    run; documented inline.

- `tests/uat/lib/harness-page-driver.ts` — wires `driveA1/A2/A3/A4`
  (replaces the 4 NOT YET IMPLEMENTED Wave-3A stubs from
  eb64521). Each wraps a single page.evaluate(() =>
  window.__mokoshHarness.assertXX()) call per the contract laid down
  by driveA6. A5+A7..A13 remain stubbed for Waves 3B+3C+3D.

- `tests/uat/harness.test.ts` (NEW) — top-level UAT orchestrator
  driving all 14 assertions sequentially against a single Chrome +
  single harness page. A0 (Tier-1 grep gate) runs pre-flight before
  any Chrome launch — mirrors
  tests/background/no-test-hooks-in-prod-bundle.test.ts forbidden-
  string inventory (9 entries; belt-and-suspenders per
  feedback-pre-checkpoint-bundle-gates.md memory). Bail-on-first-
  failure with [SKIP] markers for unreached assertions + structured
  diagnostic dump (full SW + offscreen console tail) on each failure.
  SKIP_PROD_REBUILD=1 escape hatch skips the A0-side `npm run build`
  for developer iteration.

Verification (all GREEN):
  - npx tsc --noEmit: clean (root)
  - npx tsc --noEmit -p tests/uat: clean (UAT subtree)
  - npm run build: clean; production bundle hook-free
    (9-string grep gate in vitest unit gate)
  - npm run build:test: clean; dist-test/assets/extension_page_harness-*.js
    grew from 3.87kB → 7.67kB (A1+A2+A3+A4 added)
  - SKIP_BUILD=1 npx vitest run: 93/93 GREEN
    (Wave 0+1+2 baseline 92 + 1 from the 9th grep-gate string from
    the prior commit; this commit adds zero new vitest tests — the
    A1-A4 contracts are verified at UAT-harness time only)
  - npx tsx tests/uat/a6.test.ts (standalone): 5/5 GREEN; exit 0
    (Wave-2 A6 baseline preserved through orchestrator-adjacent
    harness page surface extension)
  - npm run test:uat (full operator entry): 5/14 GREEN
    (A0 + A1 + A2 + A3 + A4); bails at A5 NOT YET IMPLEMENTED
    (Wave 3B scope, expected). Total wall clock ~25s (~5s build +
    ~5s prod-rebuild for A0 + ~15s assertion sequence).

Operator empirical-verification deferred to orchestrator (per
feedback-pre-checkpoint-bundle-gates.md — the orchestrator runs SW
CSP-safety + Node-globals + DOM-globals grep on the built bundle
before surfacing any checkpoint).

a63066a289 chore(01-13): wave-0 — clean broken Approach-A artifacts per 01-11-SUMMARY
Restore a clean baseline before promoting the c647f61 prototype to
production paths (Wave 1) and building out Approach-B driver
scaffolding (Wave 2). All deletions trace back to falsifications
documented in 01-11-SUMMARY.md.

Deleted — broken Approach-A files:
  - src/test-hooks/sw-hooks.ts
      MV3 SW blocks dynamic import (Chromium es_modules.md;
      w3c/webextensions#212). The gated `await import('../test-hooks/
      sw-hooks')` from 01-11 Wave 1 never resolved → SW silently died →
      production listeners never registered. File was dead-on-arrival;
      no fix possible while MV3 SWs disallow dynamic import. Approach-B
      replaces SW-side instrumentation with the extension-internal
      harness page's chrome.action.* + chrome.notifications.* surface
      (full privilege; no monkey-patching needed).

  - tests/uat/lib/{launch,extension,sw,offscreen,assertions}.ts
      Popup-bridge architecture (01-11 dbd977c) — falsification 2 +
      falsification 3 in 01-11-SUMMARY: `sw.evaluate` exposes only
      chrome.{loadTimes,csi}, NOT chrome.action.* / chrome.notifications.*
      / chrome.runtime.sendMessage; setPopup-juggling for extension-id
      resolution turned out to be unnecessary (browser.extensions()
      works directly per the prototype). These files will be reborn in
      Wave 2 around the extension-page architecture.

      Kept: tests/uat/lib/zip.ts (host-side JSZip work — architecture-
      agnostic; A12+A13 still use it) and tests/uat/lib/test-hook-
      contract.d.ts (type mirror — extended in Wave 3 but kept as-is here).

  - tests/uat/prototype/probe_{offscreen,sw,tabs,tabs2}.mjs
      Feasibility-research probes (01-11 spike) that empirically falsified
      the Approach-A hypotheses. The findings are encoded in 01-11-
      SUMMARY.md; the probes themselves are dead code.

  - tests/uat/harness.test.ts
      01-11 Wave 2 popup-bridge orchestrator (dbd977c). Imports the
      now-deleted tests/uat/lib/{assertions,extension,sw,offscreen,launch}
      modules — would not typecheck after this commit. Reborn in
      Wave 3A as the Approach-B orchestrator (extension-internal page
      driver + A0 grep gate + 13 assertion drivers).

Reverted — SW-side dynamic-import gate comment block:
  - src/background/index.ts lines 13-29
      The existing comment block (post-spike) described the SW-side
      gated dynamic import that never landed. Rewritten to cite 01-13
      Approach-B explicitly, link to 01-11-SUMMARY.md falsification,
      and clarify that the Tier-1 grep gate's enduring value is
      catching regressions in the offscreen chunk's __MOKOSH_UAT__
      gate (the SW chunk is hook-free by construction).

Updated — Tier-1 grep gate FORBIDDEN_HOOK_STRINGS inventory:
  - tests/background/no-test-hooks-in-prod-bundle.test.ts
      Removed: `simulateUserStop` (Approach-A naming; replaced by
      Approach-B `dispatchEndedOnTrack` which matches the W3C
      dispatchEvent semantics per RESEARCH §7 BLOCKER — track.stop()
      does NOT fire 'ended' per spec, so the simulation MUST use
      dispatchEvent).
      Added: `installFakeDisplayMedia`, `uninstallFakeDisplayMedia`,
      `dispatchEndedOnTrack`, `__mokoshOffscreenQuery`.
      Total inventory: 8 surface strings (was 5). Each MUST be absent
      from every file under dist/ post-build.

Verification (all GREEN):
  - `npm run build` — exit 0; dist/ populated.
  - `grep -rln <forbidden> dist/` — 0 matches.
  - `npm run build:test` — exit 0; dist-test/ populated; offscreen-hooks
    chunk contains `installFakeDisplayMedia` (gate runs correctly
    against the test build's distinct artifact).
  - `npx tsc --noEmit` — exit 0 (root + tests/uat/tsconfig.json).
  - `npx vitest run` — 92/92 tests passing (was 89; the +3 new tests
    come from the FORBIDDEN_HOOK_STRINGS list expanding 5 → 8 — each
    forbidden string is one parametric `it(...)` block).

Both prior-failing tests now GREEN:
  - tests/background/sw-bundle-import.test.ts (was missing dist/ → 92/92
    requires the test run to have a current dist/; vitest gate test
    rebuilds via execFile when SKIP_BUILD≠1, otherwise relies on prior
    `npm run build`).
  - tests/background/no-test-hooks-in-prod-bundle.test.ts (was failing
    on stale dist; now GREEN against the freshly-rebuilt clean bundle).

Wave 1 (next): promote tests/uat/prototype/{extension-page-harness.html,
extension-page-harness.ts,a6.test.ts} to tests/uat/ via `git mv`;
update vite.test.config.ts rollup input.

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)
