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).

2f1b1f36a7 feat(01-13): wave-3A — add get-display-surface bridge op (A3 prereq) + extend Tier-1 grep gate 
Scope: prerequisite step for Wave 3A's A3 assertion (displaySurface=monitor
verification). The page→offscreen bridge gains a new op so the harness can
query the active stream's `getSettings().displaySurface` without needing
direct offscreen.evaluate access (impossible by-construction; the only
cross-isolate path is chrome.runtime.sendMessage).

Bridge op contract (`src/test-hooks/offscreen-hooks.ts`):
  - Protocol: { type: '__mokoshOffscreenQuery', op: 'get-display-surface' }
  - Response: { displaySurface: string|null }
    • null when no current stream (recording not active)
    • 'monitor' when installFakeDisplayMedia's monkey-patched
      getSettings() reports it (production code in
      src/offscreen/recorder.ts enforces this same value — tears down
      stream + throws 'wrong-display-surface' otherwise).
  - Failure: { ok: false, error: <message> } only on getSettings throw.

Tier-1 grep gate extension (`tests/background/no-test-hooks-in-prod-bundle.test.ts`):
  - FORBIDDEN_HOOK_STRINGS: 8 → 9 entries.
  - Added: 'get-display-surface' (the literal bridge-op string;
    matches the production-bundle absence invariant — the offscreen-hooks
    module is tree-shaken in production builds by the Vite mode gate in
    src/offscreen/recorder.ts top-of-module).

Verification:
  - npx tsc: clean
  - npm run build: clean (dist/ 4 chunks; no offscreen-hooks artifact)
  - npm run build:test: clean (dist-test/ adds offscreen-hooks-DfWtG71P.js, 2.38kB)
  - SKIP_BUILD=1 vitest run no-test-hooks-in-prod-bundle.test.ts → 10/10 GREEN
    (1 build-sanity + 9 forbidden-string checks; production bundle hook-free)
  - SKIP_BUILD=1 vitest run (full) → 93/93 GREEN
    (Wave 0+1+2 baseline 92 + 1 from the 9th grep-gate string)
  - npx tsx tests/uat/a6.test.ts → A6 5/5 GREEN
    (lib-driven path preserved; bridge op addition does not interfere)

Wave 3A continuation: assertA1/A2/A3/A4 land in the next commit which
wires the harness-page surface + driver wrappers + harness.test.ts
orchestrator. This commit is the bridge prerequisite — keeping the
bridge-op extension atomic + the grep-gate extension atomic so the
'production bundle hook-free' invariant is provable BEFORE the page-side
surface lands.

eb64521321 feat(01-13): wave-2 — launchHarnessBrowser + assertions + harness-page-driver scaffolding 
Build out the Approach-B harness driver utilities atop the Wave 1
production paths. Three new files form the shared scaffold that
Wave 3's 13 assertion drivers (A1-A5, A7-A13) and the eventual
orchestrator (`tests/uat/harness.test.ts`) will all consume. The
standalone A6 driver (`tests/uat/a6.test.ts`) is rewritten to use
the new lib — behavior-preserving: A6 still PASSES 5/5 in ~7s.

New files:

  - tests/uat/lib/launch.ts (~320 LoC)
      `launchHarnessBrowser({ headless?, downloadsDir? }) → HarnessHandles`
      Extracts the Chrome-launch + victim-page + harness-page + console-
      attach pattern from a6.test.ts into a single reusable helper.
      NEW vs prototype: CDP `Browser.setDownloadBehavior` wires
      Chrome's download path to a per-run `mkdtempSync` tmp dir so A5
      (SAVE_ARCHIVE) can poll a known location without colliding with
      the operator's real downloads. Architectural commitments
      enforced (per 01-11-SUMMARY): no `--auto-select-desktop-capture-
      source` flag; victim about:blank brought to front for the
      production `chrome.tabs.query({active:true})` workaround; SW
      console attach best-effort with bounded poll; offscreen console
      attach opportunistic via `targetcreated` listener (offscreen
      target appears later, when the harness page calls
      chrome.offscreen.createDocument).

  - tests/uat/lib/assertions.ts (~210 LoC)
      Host-side assertion primitives:
        * `AssertionRecord`, `CheckRecord`, `ConsoleBuffers` types —
          mirror the page-side shape returned by `assertA*` methods.
        * `runAssertion(name, fn, buffers)` — try/catch wrapper that
          dumps the SW + offscreen console tails (last 100 lines each)
          to stderr on failure, then returns `{passed: false, error}`
          if `fn` throws.
        * `printAssertionResult(result)` — single source of truth for
          the formatted result print. Extracted from the inline
          `printResult` previously in the prototype's a6.test.ts so
          Wave 3's orchestrator can reuse it across all 14 assertions.
        * `assertEqual / assertGte / assertMatch / assertTrue` —
          structured failure messages atop node:assert/strict.
        * `waitFor(probe, predicate, timeoutMs, description)` — host-
          side polling primitive; mirrors the page-side waitFor
          semantics verbatim (they can't share a module: page-side is
          bundled into the harness HTML, host-side runs in Node).
      NO chrome.* helpers here — all chrome.* work happens inside the
      extension-internal harness page. This module is host-side ONLY
      by construction (no chrome global in Node anyway).

  - tests/uat/lib/harness-page-driver.ts (~170 LoC)
      One driver wrapper per assertion (A1..A13). Each wraps a single
      `page.evaluate(() => window.__mokoshHarness.assertXX())`.
      Centralizing this means adding/renaming an assertion = two-file
      edit (extension-page-harness.ts impl + this file) instead of
      touching every test-file caller.
      Wave 2 wires `driveA6` (proven from c647f61). The 12 Wave-3
      drivers (driveA1..A5, A7..A13) are stubbed as
      `throw new Error('NOT YET IMPLEMENTED — Wave 3<X> wires driveXX')`
      so the future orchestrator's `for (const drive of drivers)` loop
      fails cleanly on the first unimplemented one (bail-on-first-
      failure semantics). The `AssertionWithBytes` type is declared
      for A5/A12/A13 which return `bytesBase64` payloads (zip / webm
      bytes that the host side processes after the page-side
      assertion completes).

Rewrite — `tests/uat/a6.test.ts`:
  - Drops ~80 LoC of Chrome-launch + console-attach + result-print
    plumbing now living in lib/launch.ts + lib/assertions.ts.
  - Now ~70 LoC total — pure orchestration of
    launchHarnessBrowser → runAssertion(driveA6) → printAssertionResult
    → browser.close() → exit code.
  - Behavior-preserving: A6 still 5/5 GREEN with the same diagnostic
    output (SETUP, A6.1-A6.4) and the same ~7s end-to-end runtime.

Verification (all GREEN):
  - `npx tsc --noEmit` — exit 0 (root + tests/uat/tsconfig.json).
  - `npx tsx tests/uat/a6.test.ts` — exits 0 with "PASS"; 5 checks
    GREEN (SETUP, A6.1, A6.2, A6.3, A6.4). End-to-end runtime ~7s
    headless on this workstation.
  - `npm run build` — exit 0; Tier-1 grep gate GREEN (production
    bundle contains zero hook strings AND zero lib symbol names —
    the new lib files are test-only and not bundled into dist/).
  - `npm run build:test` — exit 0; dist-test/ still emits the
    extension-page-harness.html harness (lib files are host-side,
    not rollup inputs).
  - `npx vitest run` — 92/92 GREEN.

Wave 3 ready: harness-page-driver.ts has driveA1..A5/A7..A13 stubs
in place; extending requires only:
  1. Add `assertAXX` method to window.__mokoshHarness in
     tests/uat/extension-page-harness.ts.
  2. Replace the corresponding stub body in this file with the
     page.evaluate wrapper.
  3. (Wave 3A) Create tests/uat/harness.test.ts orchestrator that
     iterates over [A0 grep gate, driveA1..A13] with bail-on-fail.

eb2258a880 feat(01-13): wave-1 — promote c647f61 prototype to production paths; A6 GREEN 
Move the three load-bearing prototype files from `tests/uat/prototype/`
to their production paths under `tests/uat/`, leaving the architectural
narrative (research findings, BLOCKER citations, falsification table
references) intact. No behavioral changes — A6 still PASSES 5/5 in ~7s
end-to-end from the new paths.

File moves (git mv preserves history):
  - tests/uat/prototype/extension-page-harness.html
      → tests/uat/extension-page-harness.html
  - tests/uat/prototype/extension-page-harness.ts
      → tests/uat/extension-page-harness.ts
  - tests/uat/prototype/a6.test.ts
      → tests/uat/a6.test.ts

The `tests/uat/prototype/` directory is now empty (git does not track
empty directories; will not appear in subsequent `git status`).

Path-reference updates inside the moved files:
  - tests/uat/extension-page-harness.html: `<p>` line referencing the
    chrome-extension:// URL updated to drop `/prototype/`.
  - tests/uat/extension-page-harness.ts: file-header docstring rewritten
    to cite Plan 01-13 / Approach B / inheritance from c647f61. The
    load-bearing architectural-finding comment block (MV3 SW dynamic-
    import block falsification, Approach-B chrome.* surface summary)
    is REWORDED but its semantic content + research citations are
    PRESERVED — every load-bearing fact survives the rename.
  - tests/uat/a6.test.ts:
      * File-header rewritten to position the file as Plan 01-13's
        standalone single-assertion entry point (preserves the future-
        proof rationale: this entry stays around forever for fast TDD
        iteration on A6 even after Wave 3 folds A6 into the orchestrator
        harness.test.ts).
      * REPO_ROOT resolvePath chain corrected from `..,..,..` to `..,..`
        — the file is now two directory levels above the repo root
        instead of three. Without this fix DIST_TEST_DIR would resolve
        to a path one level above the actual repo root and
        assertBundlePresent would throw. **VERIFIED by running the
        driver: build path resolves correctly.**
      * harnessUrl constant updated to drop `/prototype/` from the
        chrome-extension://<id>/tests/uat/extension-page-harness.html
        URL — must match the rollup emission path in dist-test/.
      * Stdout labels updated: 'PROTOTYPE A6 result' → 'A6 result',
        'Plan 01-11 PROTOTYPE — A6 ... feasibility test' → 'Plan 01-13
        — A6 (Bug B canonical) standalone driver'. Inside the docstrings
        the historical 'originally landed as 01-11 prototype' provenance
        is preserved per the plan's contract.

vite.test.config.ts:
  - `rollupOptions.input` renamed `prototype_harness` → `extension_page_harness`
    pointing at the new production path. crxjs emits the harness HTML
    to `dist-test/tests/uat/extension-page-harness.html` (verified by
    `ls dist-test/tests/uat/`).
  - The `modulePreload: { polyfill: false }` line is PRESERVED — this
    is the CRITICAL SW FIX per 01-11-SUMMARY (disabling the polyfill
    is what makes the test bundle's offscreen-side dynamic import work
    without crashing in non-DOM contexts that incorrectly try to call
    document.querySelector).
  - File-header comment §4 and the inline `define.__MOKOSH_UAT__` comment
    are PRESERVED — load-bearing rationale for the dedicated build-time
    token (vs `import.meta.env.MODE === 'test'` which collides with
    vitest).

Verification (all GREEN):
  - `npm run build:test` — exit 0; dist-test/ emits
    `tests/uat/extension-page-harness.html` and `assets/extension_page_harness-*.js`.
  - `npx tsx tests/uat/a6.test.ts` — exits 0 with "A6 result: PASS";
    5/5 checks GREEN (SETUP: badge becomes REC; A6.1 badge==''; A6.2
    popup==''; A6.3 notif delta==0; A6.4 isRecording=false). End-to-end
    runtime ~7s headless on this workstation.
  - `npx tsc --noEmit` — exit 0 (root tsconfig + tests/uat/tsconfig.json).
  - `npx vitest run` — 92/92 GREEN; the moves do not touch any vitest-
    discovered files.
  - `npm run build` — exit 0; Tier-1 grep gate stays GREEN
    (the moves do not touch production code).

Wave 2 (next): build out `tests/uat/lib/{launch,assertions,harness-page-
driver}.ts` around the extension-page architecture; rewrite
`tests/uat/a6.test.ts` to use the shared lib (still PASSES 5/5).

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.

70f4f4136a docs(01-13): create UAT harness plan — Approach B (extension-internal page) 
5 waves, 9 tasks. Inherits Plan 01-11 spike-pivot rationale per
01-11-SUMMARY (commit ba5474c). Implements full 14-assertion harness
via Approach B architecture, proven by prototype c647f61.

- Wave 0: clean broken Approach-A artifacts (sw-hooks.ts, SW dynamic
  import, popup-bridge lib, feasibility probes); update Tier-1 grep
  gate to 10-string Approach-B forbidden inventory.
- Wave 1: promote c647f61 prototype (extension-page-harness +
  a6.test.ts) to production paths; A6 stays GREEN.
- Wave 2: rebuild Approach-B driver utilities (launch.ts,
  assertions.ts, harness-page-driver.ts) replacing deleted
  popup-bridge primitives.
- Wave 3 (4 task bundles): wire A1-A13 functional assertions; canonical
  Bug B (A6) + Bug A (A8) RED-on-regression demos mandatory in commit
  bodies.
- Wave 4: append 01-09 Amendment 2; update STATE.md + ROADMAP.md;
  operator brand/design checkpoint.

Open questions resolved: Wave 3 granularity = 4 bundles; tabs
permission gap = workaround retained (Phase 5 hardening); failure
isolation = single browser + bail-on-first; CI plumbing = defer.

Frontmatter validation: valid=true. Plan structure: valid=true,
task_count=9, all tasks have files/action/verify/done.

ba5474c54f docs(01-11): close as spike-pivot — SUMMARY landed, AMENDMENT-A deleted, pivots to 01-13 
Closes Plan 01-11 honestly per GSD spike-pivot pattern. Original
Approach A (Puppeteer sw.evaluate per RESEARCH §1+6) empirically
falsified across Wave 3 execution + feasibility research. Approach B
(extension-internal-page harness + offscreen synthetic stream) proven
via c647f61 prototype; full implementation moves to Plan 01-13.

What this commit does:
- ADDS 01-11-SUMMARY.md (spike-then-pivot framing per GSD artifact-
  types.md PLAN→SUMMARY lifecycle; captures retained infrastructure,
  falsified hypotheses, working prototype, bridge to 01-13)
- REVERTS frontmatter amendment block in 01-11-PLAN.md; replaces with
  closed_as/pivoted_in/closure_note pointing at SUMMARY + 01-13
- DELETES 01-11-PLAN-AMENDMENT-A.md (improvised artifact type — not
  recognized in GSD artifact-types.md; content folded into SUMMARY)

Lesson for orchestrator (captured in SUMMARY §Architectural Notes):
when a plan attempts an approach that proves infeasible, the right
move is honest SUMMARY + new plan, NOT in-place rewrite + AMENDMENT
artifact. The project's own pattern (01-08, 01-09, 01-10, 01-11
added mid-phase as new work surfaced) confirms add-new-plan-when-
scope-shifts is the established pattern.

Plan 01-09 closure via harness PASS NOT achieved by 01-11; still
requires operator UAT pending Plan 01-13 landing.

565f8fa44c docs(01-11): amendment A — pivot to extension-internal harness page 
Architectural pivot triggered by feasibility research prototype
(commit c647f61, A6 PASS 5/5 + Bug-B regression rewind verified).

Two empirical findings invalidate original architecture:
1. MV3 service workers BLOCK dynamic import. await import('test-hooks/
   sw-hooks') in src/background/index.ts silently kills the SW —
   chunk loads, await never resolves, no listeners register. Cited
   Chromium es_modules.md + w3c/webextensions#212.
2. Puppeteer WebWorker.evaluate against MV3 SW only exposes chrome.
   {loadTimes,csi} — not the extension chrome.* API surface.

The Wave 1 (cb1a729) SW-side hooks are fundamentally broken in test
builds (production unaffected — gated by __MOKOSH_UAT__ which is
false in prod). Executor must DELETE the SW-side dynamic import +
sw-hooks.ts entirely; offscreen-side hooks stay (offscreen IS a DOM
document; dynamic import works there).

Replacement (Verdict-A architecture, proven by prototype):
- Extension-internal harness page at chrome-extension://<id>/tests/
  uat/extension-page-harness.html — privileged extension context
  with FULL chrome.* API access
- Puppeteer drives the page via page.goto + page.evaluate
- For SW state: page calls chrome.runtime.sendMessage; SW responds
  via production messaging
- For getDisplayMedia: offscreen-side installFakeDisplayMedia() patches
  navigator.mediaDevices.getDisplayMedia → Canvas captureStream
  synthetic MediaStream

A6 (Bug B regression catch) PROVEN. Industry-standard pattern (MetaMask,
eyeo, Chrome MV3 official testing docs all converge).

Effort remaining: ~7-10h subagent budget (Wave 0 + bonus debug-import
commits keep; Wave 1 hooks rewire 30min; Wave 2 scaffolding 1-2h;
Wave 3 13 more assertions 4-6h; Wave 4 closure 1h).

c647f61553 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.

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.

0cd50fde94 docs(debug): import Bug B recovery-flow debug record from prior session 
Untracked file present at session spawn (per orchestrator pre-flight
intelligence). The Bug B debug investigation that produced commit
b9eeeeb (the conditional-routing fix in src/background/index.ts
RECORDING_ERROR handler that Plan 01-11 assertion 6 verifies) was
recorded under .planning/debug/resolved/01-09-recovery-flow.md but
never committed. Importing it now so the debug provenance is
preserved alongside Plan 01-11's harness coverage of the bug class.

96fa8e8e11 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).

2669ce38e7 docs(intel): designer follow-up #1 — Newsreader has no Cyrillic glyphs 
D-05 picked Newsreader as display serif. Engineering research
(01-12-RESEARCH.md §1, commit 3df2750) verified Newsreader ships NO
Cyrillic glyphs via designer's own Brief embedded subset list +
Production Type's repo README ("Google Fonts Latin Plus glyph set").

Russian display text (welcome hero, tagline) under current D-05 picks
silently falls through to Iowan Old Style → Times New Roman → serif.
Mokosh's audience is Russian-primary, so this is the default rendering
path, not a corner case.

Routing back to designer per D-05 OWNER (Design team) with 4 options:
- R1 fallback chain (Newsreader + Cyrillic-capable secondary)
- R2 substitute display family entirely
- R3 other (designer proposes)
- R4 accept the Iowan/Times fallback

Candidate Cyrillic-capable OFL serifs: PT Serif, EB Garamond, Lora,
Source Serif. PT Serif highlighted (ParaType, RU-foundry, pairs with
IBM Plex Sans).

Blocks Plan 01-12 planner spawn + Plan 01-10 welcome hero.
Plan 01-11 (harness) unaffected — non-overlapping surface.

3df2750c64 docs(01-12): research Plan 01-12 (Design Integration) — 13 areas + BLOCKER 
13 research surfaces investigated per Plan 01-12 prompt. Key findings:

- BLOCKER §1: Newsreader has no Cyrillic glyphs (verified via Decision
  Brief's own embedded @font-face subsets + Production Type README).
  Russian display text in Newsreader will silently fall through to
  serif fallback. Recommend §1 R1: add Cyrillic-capable OFL serif (PT
  Serif / EB Garamond / Lora) to --mks-font-display stack.

- §3 + §4: Mark legibility at 16 px is VERIFIED OK. rsvg-convert
  produces 406 / 784 / 1952 B PNGs at 16/48/128 — all clear Chrome
  imageUtil floors. The 2x2 weave holds at 16 px.

- §10: 8 i18n strings extracted verbatim from Brief §02 (decoded via
  Python JSON-decode of the bundler-template script). Recommended
  __MSG_*__ key names + source-file mapping table included.

- §12: D-09 (smoke gating) is NEAR-NO-OP. smoke.sh is a standalone
  bash script; nothing in src/ references it; dist/ carries no smoke
  artifacts. Recommend documenting current state + adding optional
  no-smoke-in-dist regression test.

- §13: tokens.css line 12 Google Fonts @import migration → 8 local
  @font-face rules (Plex variable consolidation collapses the
  estimated 12-18 down to 8).

All tooling verified installed on dev machine: rsvg-convert 2.60.0,
pyftsubset 4.63.0, woff2_compress, inkscape 1.4.4. No npm install
needed for execute-plan; only one-off font source TTF downloads.

7 assumptions logged for planner to surface (A1 default_locale, A2
popup DOM rework, A4 Cyrillic serif fallback are highest-impact).

5efc2a89e3 docs(intel): ingest designer-team handoff v1 + record 9 brand decisions 
Designer-team delivered two bundles (2026-05-17):
- Mokosh.zip: presentation artifacts (Decision Brief + Surface Kit standalone HTMLs)
- Mokosh Design System.zip: implementation handoff (tokens.css + mark/lockup SVGs + memo)

Designer respected every contract: codename Mokosh preserved, MV3 CSP
acknowledged (flagged dev-only Google Fonts @import in tokens.css line 12
for engineering to replace), Cyrillic-first typography (IBM Plex Sans),
WCAG AA validation noted, made recommendations not unilateral decisions.

9 decisions resolved per user ack:
- D-01..06, D-08, D-09: accepted designer defaults
- D-07 OVERRIDE: B · "Mokosh — Session Capture" (vs designer's A · just "Mokosh")
  — operator-facing manifest:name surfaces capture purpose

Brand decisions persisted to brand-decisions-v1.md;
brand-identity.md Open Questions section marked resolved with backlink.

Designer artifacts staged at .planning/intel/design-incoming/ for Plan 01-12
(Design Integration) consumption. Mokosh.zip presentation HTMLs (3.4 MB)
preserved as audit/onboarding reference; can be pruned later if repo size
warrants.

Plan 01-12 implementation handoff catalogued in brand-decisions-v1.md
§"Implementation handoff" — covers tokens.css ingestion, WOFF2 self-hosting,
SVG → PNG rasterization, manifest:name + description update,
welcome layout, VITE_DEV smoke gating.

66e6c4af74 docs(01-11): create Puppeteer UAT harness plan (14 assertions, 9 tasks) 
Retires operator-as-assertion-library role from Plan 01-09 Task 5. Bug A
(notification icon API rejection) and Bug B (state-machine routing of
user-stopped-sharing) both escaped vitest unit coverage and cost ~4-6h of
operator UAT cycles in Phase 1. Plan 01-11 ships a Puppeteer-driven Node
harness with CDP attach to SW + offscreen contexts; the 14 assertions cover
the Plan 01-08/01-09 functional contract end-to-end.

Locked from research (RESEARCH §1-§11):
- Puppeteer 25.0.2 + tsx + node:assert/strict (no vitest browser mode)
- Two-bundle separation via vite.test.config.ts (mode 'test' + dist-test/)
- Hook gating: import.meta.env.MODE === 'test' + dynamic import (Vite
  tree-shakes from production)
- Bug B trigger: track.dispatchEvent(new Event('ended')) — NOT track.stop()
  (W3C spec + empirical probe7 — track.stop does NOT fire 'ended')
- Tier-1 grep gate (tests/background/no-test-hooks-in-prod-bundle.test.ts)
  enforces zero __mokoshTest in production dist/
- Single browser, serial assertions, bail-on-first-failure (open question 4)

Wave structure (4 waves):
- Wave 0 (Task 1): puppeteer+tsx install, vite.test.config, build:test +
  test:uat scripts, Tier-1 grep gate committed GREEN.
- Wave 1 (Task 2): gated SW + offscreen hooks at src/test-hooks/; production
  bundle remains hook-free.
- Wave 2 (Task 3): harness scaffolding — tests/uat/lib/* + harness.test.ts
  with assertion 0 wired GREEN + assertions 1-13 stubbed RED.
- Wave 3 (Tasks 4-7): wire 13 assertions in 4 logically-grouped bundles
  (1-4 toolbar/displaySurface; 5-7 SAVE+BugB+ERROR; 8-10 BugA+icons+manifest;
  11-13 buffer continuity + ffprobe + zip).
- Wave 4 (Tasks 8-9): amend Plan 01-09 Task 5 to redirect functional steps
  to npm run test:uat; operator confirms brand/design.

Bug A + Bug B each have RED-on-regression canonical demos required in the
respective task's commit body — proves the harness CAN catch the regression,
not just passes under current conditions.

- triggerExtensionAction works; popup-vs-onClicked contract confirmed
- --headless=new supports MV3 + getDisplayMedia (Xvfb not required)
- offscreen page reachable via background_page target type + .asPage()
- BLOCKER: track.stop() does NOT fire 'ended' per W3C spec — Bug B harness
  must use track.dispatchEvent(new Event('ended')) instead

13-assertion implementation table + 7 pitfalls + 2-bundle build design.

9d0313acd2 docs(01-09): amend Task 5 step 11 + success criteria #3 post-Bug B 
Original step 11 expected stop-sharing → ERROR badge + recovery
notification; under Bug B fix (b9eeeeb), user-stopped-sharing is
correctly routed → IDLE (badge OFF, no recovery notification) because
it's a deliberate lifecycle event, not an error.

Amendments:
- Step 11: badge OFF (not ERROR); no recovery notification; popup cleared
- Step 12: operator clicks toolbar directly (no notification to click)
- Step 14: failure-mode list updated to match new expectations
- Step 15 added: ERROR state coverage moved to separate genuine-error step
- Success criteria #3: split user-stopped-sharing (→ OFF) from genuine
  errors (→ ERROR + recovery notification, preserved fallback)

See .planning/debug/resolved/01-09-recovery-flow.md for the debug record.

b9eeeeb386 feat(01-09): GREEN — Bug B route user-stopped-sharing → IDLE; other codes → ERROR (preserved) 
Patches the RECORDING_ERROR onMessage handler in src/background/index.ts
(lines 725-744 pre-patch) with conditional routing on the incoming
`message.error` payload:

  - 'user-stopped-sharing' → setIdleMode() (popup empties; badge OFF;
    isRecording flipped to false). Recovery notification suppressed —
    the operator stopped deliberately, surfacing one would be UX noise.
    The offscreen recorder's onUserStoppedSharing has already cleared
    the buffer (src/offscreen/recorder.ts:457 resetBuffer), so IDLE is
    the correct landing state.

  - all other codes → setErrorMode() + recovery notification, preserving
    the existing operator-facing surface for genuine capture failures
    (codec-unsupported, wrong-display-surface, capture-failed, etc.).

Closes the operator-lockout regression observed in Plan 01-09 Task 5
empirical UAT: after Chrome's "Stop sharing" banner click, the badge
stayed yellow and the popup pinned to SAVE-only, gating
chrome.action.onClicked behind the popup forever. Operator had no
restart path. With IDLE routing, the popup empties and the toolbar
click fires startVideoCapture as designed.

Tests: 83/83 GREEN (was 81; +2 from Tests E+F). tsc clean. Build exit 0.

91b4475ea1 test(01-09): RED — Bug B route user-stopped-sharing → IDLE; other codes → ERROR 
Adds Tests E + F to tests/background/badge-state-machine.test.ts pinning
the conditional-routing contract for RECORDING_ERROR onMessage:

  E (RED today): RECORDING_ERROR{error:'user-stopped-sharing'} must route
    through setIdleMode — badge OFF (text '', red #D32F2F), popup ''. The
    current handler routes ALL codes through setErrorMode, locking the
    operator out of restart (popup wins toolbar.onClicked forever).

  F (GREEN today, preserved after fix): RECORDING_ERROR with any other
    error code (representative: 'codec-unsupported') continues to route
    through setErrorMode — badge ERR + yellow #F9A825 + popup html. This
    is the defensive-fallback regression pin guarding against the patch
    over-rotating to IDLE for all codes.

949aa03db5 docs(intel): design system + assets spec for designer-team handoff 
Two new cross-phase intel docs surfacing the visual + interaction
language and the concrete asset deliverables list.

Triggered by Plan 01-09's notification-icon failure: the original
placeholder PNGs (icons/icon{16,48,128}.png at 79/123/306 bytes)
are too small for chrome.notifications.create's imageUtil validation.
Plan 01-09 closeout blocks on valid replacement icons.

design-system.md captures:
- Brand voice (quietly competent operator-tool; not playful)
- Identity (Mokosh codename + "AI Call Recorder" display name)
- Color tokens (semantic state + UI surfaces; WCAG AA validated)
- Typography (system fonts only; type scale)
- Iconography (solid filled, 24px grid, neutral mark + state via badge)
- Spacing (4px base scale)
- Motion (conservative; reduced-motion-aware)
- Component conventions (toolbar action, notification, popup, welcome)
- Accessibility & i18n (Russian-first, contrast floors)
- Open design decisions (mark concept, pulsing badge, tagline)

assets-spec.md captures:
- Priority 0 (blocks Plan 01-09): icons 16/48/128 with min file sizes
  + dimension/format requirements + validation commands
- Priority 1 (Plan 01-10): welcome page hero, optional 192px icon
- Priority 2 (future phases): per-state icon variants, popup polish,
  runbook visuals
- Three implementation paths: auto-generated placeholders (interim),
  design-first (commission), hire/commission

User will delegate execution to designer team; specs are handoff-ready
with binding technical floor + designer-judgment aesthetic direction.

06dee246c9 feat(01-09): GREEN — toolbar onClicked + badge state machine + onStartup notification + SAVE-only popup 
Plan 01-09 Task 4 GREEN — flips all 13 Task 3 RED tests to GREEN:

src/background/index.ts:
  • Badge palette + notification id prefix constants (SCREAMING_SNAKE).
  • setBadgeState(state) helper: 3-state machine REC/OFF/ERROR with
    deterministic setBadgeText + setBadgeBackgroundColor + setTitle.
    Each chrome call wrapped in try/catch (defense in depth).
  • setIdleMode / setRecordingMode / setErrorMode helpers — drive the
    setPopup dance: '' in OFF (so onClicked fires), html path in REC/
    ERROR (so popup opens for SAVE).
  • startVideoCapture wires setRecordingMode on success, setErrorMode
    in catch.
  • chrome.action.onClicked.addListener — direct toolbar-to-picker flow
    (no popup needed for start). isRecording guard prevents double-start.
  • chrome.runtime.onStartup.addListener — fires once per browser
    session; creates mokosh-startup- notification inviting recording.
  • chrome.notifications.onClicked.addListener — T-1-09-01 spoofing
    mitigation via 'mokosh-' prefix gate; clears notification + invokes
    startVideoCapture (notification click is a valid activation gesture).
  • RECORDING_ERROR onMessage branch — setErrorMode + creates a
    mokosh-recovery- notification inviting the operator to restart.
  • initialize() calls setIdleMode at SW boot — ensures fresh OFF state
    on every (re-)spawn including Chrome's idle-eviction respawn.
  • All new listener registrations wrapped in try/catch so unit-test
    chrome stubs that don't define action/notifications/onStartup don't
    crash SW load (preserves the 5 pre-existing request-id-protocol +
    1 port-lifecycle-continuous tests as GREEN).

src/popup/index.ts:
  • Removed checkPermissions + requestPermissions functions entirely
    (no more REQUEST_PERMISSIONS round-trip on popup open).
  • popupState defaults isRecording=true, hasPermissions=true under
    SAVE-only charter — the popup ONLY opens when recording is active
    (REC/ERROR setPopup html path), so SAVE button is always enabled.
  • init() calls updateUI() directly (no async permission probe).
  • Empty-state copy updated: 'Откройте запись через иконку расширения'
    (Open recording via the extension icon — points operator back to
    the toolbar for starting a new session).
  • saveArchive() simplified: no permission re-check.

manifest.json:
  • Added 'notifications' to permissions array (preserves all existing).
  • default_popup retained — popup still opens in REC/ERROR modes.

smoke.sh (W-04 5-sub-step update):
  • SHARE_TARGET='Entire screen' (was 'Mokosh Smoke Test').
  • Added 14-line locale-fallback comment block citing Chromium
    generated_resources.grd as authoritative source + 4 known locale
    strings + KEEP_PROFILE=1 fallback path.
  • <title> changed to 'Mokosh Smoke Test — monitor mode' to keep tab
    title distinct from the screen-source string.
  • <ol> instruction updated: picker auto-accepts entire screen, not
    the tab. Body intro paragraph also updated.
  • T+/wall timer overlay (commit 923aaca) preserved — no behavioral
    change to polling/Downloads-snapshot/ffprobe-gate logic.

Tests: 13/13 new GREEN; full suite 18 files / 81 tests / all GREEN.
tsc --noEmit exit 0. npm run build exit 0; dist/manifest.json has

2d7ff7d4e3 test(01-09): RED — toolbar-onClicked + badge state machine + onStartup notification + popup SAVE-only 
Plan 01-09 Task 3 RED — 13 tests across 3 new files:

tests/background/toolbar-action.test.ts (5 tests):
  A: chrome.action.onClicked.addListener registered at SW init
  B: onClicked while not recording triggers startVideoCapture
  C: onClicked while isRecording does NOT double-start
  D: setPopup('') in OFF mode, popup html path in REC mode
  E: popup init does NOT send REQUEST_PERMISSIONS + saveButton enabled
     (W-02 fix — without jsdom, uses node-env document stub)

tests/background/badge-state-machine.test.ts (4 tests):
  A: REC state = text 'REC' + #00C853 green + Recording title
  B: OFF state = text '' + #D32F2F red + Not recording title
     (fired at SW init via initialize → setIdleMode)
  C: ERROR state = text 'ERR' + #F9A825 yellow + error title
  D: RECORDING_ERROR onMessage triggers setBadgeText('ERR') within microtask

tests/background/onstartup-notification.test.ts (4 tests):
  A: chrome.runtime.onStartup.addListener registered at SW load
  B: onStartup fires exactly one mokosh-startup- notification
     with basic type + 'Mokosh ready' title + Click-instructed message
  C: notifications.onClicked with mokosh- id clears + triggers START_RECORDING
  D: RECORDING_ERROR onMessage triggers mokosh-recovery- notification

Task 4 will flip all 13 to GREEN by adding the listeners + state machine
+ helpers in src/background/index.ts, popup SAVE-only, manifest update.

Deviation Rule 3: jsdom not in node_modules; refactored Test E to use a
node-env document stub instead of @vitest-environment jsdom pragma.

de162b4293 feat(01-09): GREEN — displaySurface:'monitor' constraint + post-grant validation 
Plan 01-09 Task 2 GREEN — flips Task 1 tests 1, 2, 4 to GREEN:

1. CaptureErrorCode union extended with 'wrong-display-surface'.
2. classifyCaptureError branch matches 'wrong-display-surface' prefix.
3. getDisplayMedia call carries {video:{displaySurface:'monitor',
   cursor:'always'},audio:false} (Plan 01-09 D-15-display-surface +
   Phase 5 cursor:'always' opportunistic lift).
4. Post-grant validation block reads track.getSettings().displaySurface;
   on non-monitor pick: tears down stream, nulls mediaStream, throws
   wrong-display-surface Error which routes through the existing
   classifyCaptureError + RECORDING_ERROR broadcast path.

Type note: lib.dom.d.ts MediaTrackConstraints omits 'cursor' — used
explicit type-widening cast (NOT 'as any') to add the field without
suppressing other type checking.

Tests: 4/4 GREEN; full suite 15 files / 68 tests / GREEN.

1. getDisplayMedia called with strict {video:{displaySurface:'monitor',

2. Non-monitor pick (browser/window) tears down stream + emits
   RECORDING_ERROR wrong-display-surface.
3. Monitor pick does NOT trip wrong-display-surface (over-fire guard).
4. classifyCaptureError routes 'wrong-display-surface' message prefix
   to 'wrong-display-surface' code.

Task 2 will flip Tests 1, 2, 4 to GREEN by adding constraints +

e40949d1d2 test(01-08): regenerate last_30sec.webm fixture + split remux input/output fixtures 
Plan 01-08 Task 5 closeout. The post-B+ smoke run produced a working
single-EBML WebM (28.76s, 676 frames, 1.89 MB, monotonic 0→28.76s
timestamps). Operator-confirmed empirically (timer overlay in smoke
HTML showed the latest frames matched expectations).

Two-fixture split resolves a test-design conflict surfaced when
last_30sec.webm flipped from pre-remux input shape to post-remux
output shape:

- tests/fixtures/last_30sec.webm — POST-REMUX output (single EBML,
  41 ffmpeg dry-run lines). Validates webm-playback.test.ts'
  playable-duration + structural assertions.

- tests/fixtures/raw-3ebml-concat.webm — PRE-REMUX input (3-EBML
  concat, 299 ffmpeg dry-run lines = 3 segment boundaries).
  Preserved from the original 2026-05-15 Phase 1 closure fixture.
  Used by webm-remux.test.ts to test that remuxSegments correctly
  transforms 3-EBML input → single-EBML output.

tests/background/webm-remux.test.ts FIXTURE_PATH updated to point at
raw-3ebml-concat.webm; the hardcoded EBML byte offsets [0, 509038,
970967] and frame bounds [905, 912] remain valid against that
preserved input.

Result: 64/64 vitest GREEN (was 61/64). tsc clean. Build exit 0.

923aaca3a8 test(smoke): add T+/wall timer overlay to smoke page for D-13 stale-gap measurement 
The smoke test page now displays a fixed top-right overlay showing
elapsed-since-load (T+) and wall-clock (HH:MM:SS). Operator can:
- Note timer values at save-click moment
- Examine the saved WebM's last frame for the visible timer values
- Compute (save-click value − last-frame value) = operator-visible
  "stale gap" the D-13 architecture leaks

This converts the subjective "video isn't latest" observation into a
precise measurement, enabling correct routing:
- Gap ≤ 10s → matches D-13 in-flight-segment trade-off (architectural,
  not a regression; would inform a follow-up plan to reduce the gap)
- Gap > 10s → real regression (ring buffer rotation broken or similar)

Pure diagnostic addition to smoke.sh; no extension code changed.

073e7b3584 docs(debug-01-08): update Resolution — B+ polyfill closed Layer 2 gap 
The 01-08 fix took TWO iterations, not one. Iteration 1
(commits 52c7636 + 74400ae, archived in cc6e81a) resolved
the SW INIT crash via resolve.alias for ebml + chrome.* mock
for the Tier-1 Layer 1 gate. That landing masked a SECOND
defect — ts-ebml's EBMLDecoder constructor crashes with
`ReferenceError: Buffer is not defined` because MV3 SW has
no Buffer global. The runtime path is unreachable at module
init (EBMLDecoder is only constructed when remuxSegments
runs, which only fires from the SAVE_ARCHIVE handler), so
Layer 1 of the gate could not catch it.

Iteration 2 (commits dd7bf00 + 761dfc0) closed that gap by
extending the Tier-1 gate to Layer 2 (source-imports
webm-remux.ts, invokes remuxSegments — caught the Buffer
bug empirically) and applying B+ — vite-plugin-node-polyfills
with narrow Buffer-only config — to provide Buffer at SW
runtime via bundler-level import rewrite.

Updates to the debug archive:
- frontmatter `updated:` bumped to 12:25Z
- two new Evidence entries (12:15Z Layer 2 RED, 12:20Z B+
  GREEN) document the iteration-2 empirical path
- one new Eliminated entry: "C-config alone is sufficient" —
  FALSIFIED by Layer 2 (the resolve.alias fix from iteration
  1 is necessary but not sufficient; ts-ebml's runtime Buffer
  use is an orthogonal concern that requires the polyfill)
- Resolution.root_cause rewritten to describe BOTH defects
  (bundler-config + runtime-Buffer) and explain why they
  surfaced sequentially
- Resolution.fix rewritten with iteration-1 / iteration-2
  structure, citing all 4 commits across both iterations
- Resolution.verification rewritten with explicit Layer 1
  vs Layer 2 verification claims and the full vitest count
  (62 passing, 2 failing — pre-existing fixture-dependent
  webm-playback duration tests, unchanged)
- Resolution.files_changed lists all 4 commits across both
  iterations + this archive update

The session was correctly resolved-and-archived after
iteration 1 with the information then available; iteration
2 is an additive correction once the extended gate surfaced
the second defect. Per the project's
feedback-pre-checkpoint-bundle-gates memory, the extended
Tier-1 gate is now the canonical bundle-loadability check
any future plan executor with SW surfaces must run before
operator-empirical checkpoints.

761dfc0388 test(debug-01-08): extend Tier-1 gate to Layer 2 (exercises remuxSegments) 
The original Layer 1 gate (74400ae) verified module-init under
SW-simulated globals. It did not exercise remuxSegments — the
actual runtime code path the SW reaches on SAVE_ARCHIVE.

Layer 2 imports webm-remux.ts as SOURCE in a spawned Node child
under SW-simulated globals, invokes remuxSegments with a synthetic
single-segment EBML payload, and classifies the outcome:
- `ok` (returned a Blob) or `domain_error` (e.g. invalid EBML
  header — proves runtime path is structurally reachable) → PASS
- `sw_incompat` (ReferenceError for Node globals, EvalError /
  unsafe-eval for CSP) → FAIL with the specific error surfaced

This is the gate that empirically caught the ts-ebml Buffer issue
addressed by the preceding polyfill commit; it closes the loop
between "bundle loads" (Layer 1) and "bundle works at runtime"
(Layer 2).

Polyfill-aware design: Layer 2 leaves `Buffer` AVAILABLE in the
child env (split strip list: SW_SOURCE_STRIP_GLOBALS omits
'Buffer'). The vite-plugin-node-polyfills rewrite is BUNDLER-LEVEL
(Buffer → imported polyfill chunk) and does not apply when source
is loaded outside Vite. Leaving Buffer available faithfully
models what the polyfilled bundle provides at SW runtime, while
keeping the classifier ready to flag Buffer regressions if the
polyfill ever gets removed. `process`/`window`/`document` remain
stripped (polyfill is configured globals.process: false; SW
genuinely lacks DOM).

Node 24 native TS transform (`--experimental-transform-types`)
is used for source loading; a tiny inline resolution hook
appends `.ts` to extensionless relative specifiers, mimicking
vite/rollup's extension policy. Hook is base64-encoded as a
data: URL so the test stays self-contained (no on-disk hook file).

dd7bf00d1d fix(01-08): B+ — vite-plugin-node-polyfills for Buffer (resolves runtime ts-ebml crash) 
Layer 2 of the extended SW-bundle-import gate caught a runtime
ReferenceError: Buffer is not defined at EBMLDecoder.constructor
(this._buffer = Buffer.alloc(0)). Reached from remuxSegments via
extractFramesFromSegment for every input segment — would crash
the SW on every SAVE_ARCHIVE click in real Chrome.

ts-ebml has a 5-year-old open issue (legokichi/ts-ebml#37,
"Can't use Buffer in browser") acknowledging the incompatibility
with no maintainer fix. The canonical Vite workaround is
vite-plugin-node-polyfills with a narrow Buffer-only config (per
the plugin author's official docs).

Changes:
- vite-plugin-node-polyfills@0.27.0 added as devDependency
- vite.config.ts adds nodePolyfills plugin with narrow config:
  include: ['buffer'], globals.Buffer: true, globals.global: false,
  globals.process: false, protocolImports: false (Buffer only, no
  stdlib pull-in)
- bundle delta: SW chunk 373.05 kB (-0.49 kB vs C-config alone);
  +27.48 kB shared polyfill chunk (index-CgqXENQe.js, used by SW
  and offscreen). Net cost ~26.3 kB for full Buffer support.

Bundle verification:
- bundled EBMLDecoder.js now reads `this._buffer = me.alloc(0)`
  where `me` is the imported polyfill Buffer (was `Buffer.alloc(0)`
  against undefined globalThis.Buffer). Same rewrite applied to
  all 3 Buffer.alloc/Buffer.concat/Buffer.from sites in ts-ebml.
- bundle does NOT depend on globalThis.Buffer (the polyfill
  rewrites references as imports, not as global assignments) —
  Layer 1 of the gate still strips Buffer from globalThis and
  passes, confirming this.

Layer 2 gate: RED → GREEN. resolve.alias.ebml fix from commit
52c7636 preserved — still required for ebml CJS-interop;
the polyfill addresses an orthogonal runtime concern.

74400ae6ac test(debug-01-08): complete SW-bundle-import gate — mock chrome.* surface 
The Tier-1 SW-bundle-loadability gate (c75854c) stripped
Buffer/process/window/document from the spawned Node isolate
but did not mock chrome.*. A correctly-bundled SW that reaches
addListener calls at module init would (correctly) progress to
chrome.runtime.onMessage.addListener(...) and throw
ReferenceError because chrome was undefined — a false-positive
RED.

This commit adds a minimal Proxy-based chrome.* stub that
no-ops any chrome.<api>.<method>(...) chain. The gate now
verifies what its file-header comment claims: "bundled artifact
reaches module-init completion under SW-simulated globals."

RED->GREEN: the gate now correctly passes against the post-fix
bundle and would catch any future regression in SW
bundle-loadability.

52c76362ae fix(01-08): resolve ebml via CJS main entry to bypass Vite/Rollup tree-shake bug 
Vite's @rollup/plugin-commonjs failed to bridge ts-ebml's
`require("ebml")` against ebml's mixed-main/module/browser package.
Rollup tree-shook ebml.esm.js entirely, leaving `var Pc={}` as a
dangling placeholder. ts-ebml/tools.js's destructure
`{tools:f}=Pc` threw TypeError at SW top-level module init,
blocking handler registration -> chrome://serviceworker-internals
Status=STARTING forever.

`resolve.alias: { ebml: 'ebml/lib/ebml.js' }` forces resolution to
the CJS main entry whose assignment-style exports survive
plugin-commonjs's namespace allocation. Empirically verified:
bundle init progresses ~340 KB further; readVint error gone.

Probes C1 (resolve.mainFields), C2 (treeshake.moduleSideEffects),
C3 (C1+C2 combined), C4 (commonjsOptions.strictRequires) were
all falsified before C-config landed.

c75854cbef test(debug-01-08): RED Tier-1 SW-bundle-loadability gate + corrected hypothesis 
Adds tests/background/sw-bundle-import.test.ts that loads the built SW
chunk under SW-simulated globals (Buffer/process/window/document stripped)
via a spawned Node child process. Pins the orchestrator-side gap that
caused Plan 01-08's SW init crash: the prior deps test only checked
SOURCE packages under default Node globals, never the bundled output, so
Vite/Rollup's CJS-interop bug (tree-shaking the `ebml` package while
leaving a dangling `{tools:f}=Pc` destructure against an empty Pc) went
undetected until operator empirical smoke.

RED against HEAD aabbd0c — failure surfaces the exact production error
("Cannot read properties of undefined (reading 'readVint')"), proving
the test is a true regression gate, not a tautology.

Also rewrites .planning/debug/01-08-sw-incompatibility.md to reflect the
actual root cause (Vite/Rollup CJS interop) rather than the orchestrator's
initial falsified hypothesis (new Function + Buffer globals — disproven
by Node simulation showing the throw fires at module-init line 12:33809
before any CSP-eval or Buffer-ref code path executes).

Full vitest: 60 passing + 3 RED (this gate + the 2 pre-existing Task 5
fixture-dependent duration tests). No regressions.

Per feedback-pre-checkpoint-bundle-gates.md (auto-loaded memory): any
future plan executor whose work surfaces a SW must run this test before
any operator-empirical checkpoint.

35db6c2357 feat(01-08): swap mergeVideoSegments -> await remuxSegments at call site 
- src/background/index.ts now imports remuxSegments from './webm-remux'
  and awaits it in createArchive instead of synchronously calling the
  retired file-concat mergeVideoSegments.
- mergeVideoSegments function declaration deleted entirely; only a
  retirement comment remains naming Plan 01-08 D-14-remux as the
  superseding decision.
- EmptyVideoBufferError throw paths preserved on (a) zero segments
  AND (b) zero-byte output. Error message free-text changed from
  "merged video blob is zero bytes" to "remuxed video blob is zero
  bytes"; pre-flight grep (W-01 fix from plan checker pass)
  confirmed no downstream consumer matches on the legacy string —
  request-id-protocol.test.ts asserts on error.code ('empty-video-
  buffer'), not the free-text message.
- createArchive remains async (was already declared async); saveArchive
  already awaits createArchive so no upstream signature changes.
- Stale comment in decodeBufferSegments referencing mergeVideoSegments
  updated to reflect the new remux pipeline (Rule 3: keep forward-
  references accurate).
- CONTEXT.md amendment provenance verified intact via 4 grep checks
  (B-01 fix from plan checker, folded from retired Task 6):
  (a) D-14-remux disambiguated marker present  (1 match)
  (b) original D-13 line preserved              (1 match)
  (c) D-17-port-lifecycle amendment intact      (1 match)

- Parses each VideoSegment via ts-ebml Decoder; tracks current Cluster

- Re-emits all frames through a single webm-muxer Muxer<ArrayBufferTarget>
  configured with type:'webm', codec:'V_VP9', and adjusted monotonic
  timestamps (segmentBaseMs + cluster.Timestamp + block.timecode,
  microseconds for the muxer).
- Picks track info (PixelWidth, PixelHeight, optional CodecPrivate)
  from first segment that exposes them; falls back to 1024x768 with
  a logged warning per Task 5's failure-mode (e).
- Defensive: empty input -> empty Blob (Test 5); sort by timestamp
  ascending (mirrors retired mergeVideoSegments order discipline).
- 434 LOC including extensive JSDoc per project style; 8 small named
  helpers, no nested mega-functions.
- Empirically: 3-segment fixture -> 912 frames in 29.954 s,

- Note: webm-muxer 5.1.4 upstream-deprecated in favor of Mediabunny; the
  pinned version still meets the d13 architectural requirement
  (single-EBML output via addVideoChunkRaw). Migration to Mediabunny is

Plans cover the post-D-13 architecture and the auto-start UX charter
expansion that landed during 2026-05-16 UAT:

- Plan 01-08 — WebM remux via ts-ebml@3.0.2 + webm-muxer@5.1.4. Replaces
  the broken file-concat in mergeVideoSegments with a real single-EBML
  remux. Drives the 2 RED tests in tests/offscreen/webm-playback.test.ts
  to GREEN. Regenerates the canonical fixture against the remuxer.
  5 tasks (4 TDD + 1 operator empirical checkpoint), wave 1.

- Plan 01-09 — Whole-desktop constraint (displaySurface:'monitor',
  cursor:'always') + post-grant validation, chrome.action.onClicked
  direct toolbar invocation, chrome.action badge state machine
  (REC/OFF/ERROR), chrome.runtime.onStartup notification + recovery
  notification on onUserStoppedSharing, popup scoped to SAVE-only.
  17 new test assertions across 4 test files. smoke.sh updated to
  auto-select an entire screen. 5 tasks (4 TDD + 1 operator empirical
  checkpoint), wave 2 (depends on 01-08).

- Plan 01-10 — chrome.runtime.onInstalled welcome tab on first install
  via chrome.storage.local guard; vanilla welcome.html/ts/css bundle
  with single "Начать запись" button consuming install-time activation.
  Uses centralized Logger pattern. 4 tasks (3 TDD + 1 operator empirical
  checkpoint), wave 3 (depends on 01-09).

CONTEXT.md amendment block appended with 4 disambiguated decisions:
- D-14-remux: WebM remux supersedes D-13 file-concat
- D-15-display-surface: whole-desktop + cursor visibility lifted from
  Phase 5 deferral
- D-16-toolbar: toolbar onClicked + popup SAVE-only + badge state
  machine + onStartup/recovery notifications
- D-17-onboarding: welcome tab on first install (distinct from
  D-17-port-lifecycle from Option C)
The earlier D-17 port-lifecycle heading also renamed to hyphenated
form for cross-ref consistency.

Plan-check loop: 3 iterations (initial + 2 revisions). Iteration 1
surfaced 11 findings (2 BLOCKER + 6 WARNING + 3 INFO); all addressed
via revision iter 1 with checker-recommended fixes. Iteration 2
surfaced 3 derivative regressions (literal-string grep anchors from
the iter-1 fixes did not match live CONTEXT.md); all addressed in iter
2 with empirically-validated literals. Iteration 3 PASSED clean.

Validation: gsd-sdk frontmatter.validate + verify.plan-structure both
return valid=True for all 3 plans. Plan 01-08 Task 4 verify-chain
grep tested end-to-end against live CONTEXT.md (exit 0).

bc310d98cf revert(01): reopen Phase 1 — D-13 multi-EBML-concat is unplayable 
REQ-video-ring-buffer flipped from [x] back to [ ]. ROADMAP.md Phase 1
row reverted from [x] Closed 2026-05-15 to [ ] reopened 2026-05-16.
STATE.md status flipped phase_complete → phase_reopened with full
historical narrative preserved.

Root cause (confirmed at byte level by gsd-debugger 2026-05-16):
D-13's concat-of-self-contained-WebM-segments architecture produces a
3-EBML-header WebM that standards-compliant Matroska parsers
(mpv, ffmpeg, Chrome HTMLMediaElement) play only as the first segment
(~9.94 s) and silently drop the remaining 2 segments. Confirmed via
operator mpv drag-drop test of BOTH the canonical 2026-05-15 closure
fixture and the 2026-05-16 UAT-produced fixture — both exhibit the
same broken playback.

The 2026-05-15 "operator-confirmed clean Chrome playback" assessment
was insufficient: it verified the file plays without freezing but did
not measure total duration. Phase 1's primary deliverable
(REQ-video-ring-buffer / SPEC §10 #7) is therefore NOT satisfied.

Fix path chosen by user: ts-ebml (parse) + webm-muxer (write) to
replace mergeVideoSegments file-concat with real single-EBML remux.
Will land as Plan 01-08 via fresh /gsd-plan-phase ceremony.

RED test landed in tests/offscreen/webm-playback.test.ts (2 new
assertions on container-format-duration + ffmpeg-full-decode-duration).
2 failures, 53 baseline tests still GREEN.

Option C port-lifecycle refactor (debug session
empty-archive-port-race, commits 674c415..f0871c0) DID land cleanly
and is retained — that fix was orthogonal and correctly resolved the
silent-empty-archive symptom that previously masked this deeper bug.
