From f44ca3afbaa12b034e665f2484f1124adbbc1e78 Mon Sep 17 00:00:00 2001 From: Mark Date: Mon, 18 May 2026 09:24:06 +0200 Subject: [PATCH] =?UTF-8?q?wip(01-11):=20wave-3=20partial=20=E2=80=94=20A1?= =?UTF-8?q?+A4=20attempted,=20popup-bridge=20SW=20state=20query=20unreliab?= =?UTF-8?q?le?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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:///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.
