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.

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`

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
