UAT harness extended with 5 new page-side assertions following the 01-13 Approach B pattern (page-side assertA* + host-side driveA* wrapper + harness.test.ts orchestrator entry): A18 — Lora WOFF2 reachable from harness page (font self-host MV3 CSP invariant). Walks document.styleSheets for the first @font-face rule referencing Lora, resolves the rebased asset URL (handles Vite's content-hashing), fetches, asserts byteLength >= 40_000 (subset Lora is ~49 KB) + WOFF2 signature 'wOF2'. 4 checks. A19 — icons rasterized from Loom mark (not Bug A placeholders). Fetches icon128.png, parses IHDR bytes 24-25 (bit-depth + color-type), asserts (8, 6) RGBA vs the placeholder (16, 2) RGB. 2 checks. A20 — manifest:name resolves via chrome i18n. Reads chrome.runtime.getManifest().name; asserts it matches EN extName 'Mokosh — Session Capture' OR RU 'Mokosh — Запись сессии' (robust to whatever locale Chrome uses); explicitly checks no __MSG_ placeholder leaks. 2 checks. A21 — --mks-font-display resolves to Lora stack. Creates transient .mks-display-1 probe div, reads getComputedStyle.fontFamily, asserts the stack starts with 'Lora' or '"Lora"' (accommodates both quoted + unquoted forms across Chrome versions); explicitly checks no Newsreader leak (R2 substitution complete). 2 checks. A22 — welcome page tokens.css adoption (CONDITIONAL on Plan 01-10). Skip-gate on missing welcome.html: catches both HTTP 404 AND network-layer fetch failure (Chrome extensions throw TypeError 'Failed to fetch' for non-web_accessible_resources paths). On reachable: extracts <link rel=stylesheet> hrefs, fetches each, asserts >= 3 var(--mks-*) usages OR tokens.css reference. 1 check. Companion changes: - tests/uat/extension-page-harness.html gains `<link rel="stylesheet" href="../../src/shared/tokens.css">` so A18 + A21 have the @font-face rules + .mks-display-1 class + CSS custom properties resolvable via document.styleSheets + getComputedStyle. Vite's crxjs plugin handles the asset path rebasing at build:test time. - tests/uat/lib/harness-page-driver.ts: driveA18..driveA22 wrappers following the established driveA8 pattern (page.evaluate → window. __mokoshHarness.assertXX). No new host-side fs/ffprobe primitives; all A18-A22 work is page-side. - tests/uat/harness.test.ts: orchestrator drivers list extended with A18-A22 between A14 and A23. FORBIDDEN_HOOK_STRINGS UNCHANGED at 12 entries post-Plan-01-14 (A18-A22 use production chrome.* + fetch + getComputedStyle exclusively; no new test-mode symbols). Verification (this commit): - npm run test:uat: 21/21 GREEN (was 16/16 post-01-14) - SKIP_BUILD=1 npm test: 147/147 GREEN - Tier-1 grep gate: 13/13 GREEN (no FORBIDDEN_HOOK_STRINGS growth) - npx tsc --noEmit: clean - npm run build + npm run build:test: both succeed The chain of A1..A14 + A18..A22 + A23 runs in ~95 seconds end-to-end under Puppeteer headless mode against the bundled Chrome at ~/.cache/puppeteer/chrome/linux-148.0.7778.167.

Mokosh UAT harness (Plan 01-11)
Puppeteer-driven Node script that runs 14 assertions end-to-end against a real Chrome instance loaded with the Mokosh extension. Replaces Plan 01-09 Task 5's operator-empirical functional verification (the operator retains only step 1 — build — and step 14 — brand/design acceptance).
Quick start
npm run test:uat
This builds dist-test/ (the hook-enabled bundle) and runs the harness.
Exit 0 means all 14 assertions passed. Final line: UAT harness: 14/14 assertions passed.
Local-debug mode
HEADLESS=0 npm run test:uat
Opens a real Chrome window so you can watch the picker auto-accept, the badge transitions, the popup appear, etc.
Developer iteration tricks
# Skip the production build inside assertion 0 (uses existing dist/):
SKIP_PROD_REBUILD=1 npm run test:uat
# Run the harness against an existing dist-test/ (skip npm run build:test):
npx tsx tests/uat/harness.test.ts
Assertion catalog
| # | Title | Bug class | Hook used |
|---|---|---|---|
| 0 | Production bundle has no test-hook leaks | T-1-11-01 | filesystem grep |
| 1 | SW bootstrap → setIdleMode | — | sw.evaluate |
| 2 | Toolbar onClicked-idle → REC + popup | — | triggerExtensionAction |
| 3 | Offscreen displaySurface === monitor | D-15 | __mokoshTest.getCurrentStream |
| 4 | Toolbar onClicked-recording → popup, no new offscreen | — | targets count |
| 5 | SAVE_ARCHIVE → download fires | — | downloads polling |
| 6 | BUG B: simulateUserStop → badge OFF + no recovery notif | b9eeeeb |
dispatchEvent('ended') |
| 7 | RECORDING_ERROR codec-unsupported → ERR + recovery notif | — | sendMessage |
| 8 | BUG A: onStartup → mokosh-startup- notification creates | a881bf0 |

| 9 | Icon file sizes meet floors | Bug A precondition | sw.evaluate(fetch) |
| 10 | Manifest has notifications + 3 icons | Bug A precondition | chrome.runtime.getManifest |
| 11 | 35s recording → segments.length >= 3 | D-13 | __mokoshTest.getSegmentCount |
| 12 | ffprobe on extracted webm exits 0 | Plan 01-08 | jszip + execFile |
| 13 | Archive shape — video + meta.json version match | Plan 01-07 | jszip |
Failure isolation
Single browser, serial assertions, bail on first failure for setup- dependent assertions (assertion 0 abort means refusing to launch a potentially-leaky bundle). Per-assertion bail keeps the diagnostic output unambiguous — see RESEARCH §5 + Plan 01-11 open-question resolution 4.
On failure, the harness dumps the last 30 lines of SW console + last 30 lines of offscreen console (captured live during the run) to stderr BEFORE rethrowing — gives you contextual triage without needing to re- run with debug logging.
Known gotchas
Locale-specific picker auto-accept
The --auto-select-desktop-capture-source=Entire screen Chrome flag
auto-accepts the screen-share picker. The string "Entire screen" is
en_US-specific. If your Chrome is set to a non-English locale, the
picker option label will differ and the auto-accept will silently fail
(picker stays open; assertion 2 times out).
Fallback: switch your Chrome user-data-dir's locale to en_US for
harness runs, OR adjust the launch arg in tests/uat/lib/launch.ts to
match your locale's equivalent string.
dev-dep Chromium binary size
puppeteer pulls a ~150 MB Chromium binary at npm install time. CI
must accept this. Production npm install --omit=dev skips it cleanly.
Xvfb is NOT required
Per Plan 01-11 RESEARCH §3 empirical probes against Chrome 148, the
--headless=new mode handles screen capture without Xvfb on Linux CI
runners. If a future Chrome regresses this, Xvfb :99 & DISPLAY=:99 npm run test:uat is the fallback.
CI runner screen-capture concern
The 35s recording assertion (A11) captures whatever is on screen during that window. CI MUST run the harness in an isolated container with no concurrent workload — see T-1-11-02 in Plan 01-11's threat model.
Real Chrome download (assertion 5 → A12)
The harness configures per-page download behavior via CDP to a fresh
os.tmpdir()/mokosh-uat-downloads-* directory; downloads are NOT
written to your real ~/Downloads. The temp directory is deleted by OS
tmpdir GC.
