From c647f6155311ce08823342da009b5da53f16908c Mon Sep 17 00:00:00 2001 From: Mark Date: Mon, 18 May 2026 12:06:08 +0200 Subject: [PATCH] =?UTF-8?q?wip(01-11):=20prototype=20=E2=80=94=20A6=20via?= =?UTF-8?q?=20test-page+bridge+synthetic-stream=20PASSES?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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:///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.
