From d793c9e1e536fc4769cee9098e6599bec6469805 Mon Sep 17 00:00:00 2001 From: Mark Date: Tue, 19 May 2026 10:24:39 +0200 Subject: [PATCH] =?UTF-8?q?feat(01-13):=20wave-3D=20=E2=80=94=20A11+A12+A1?= =?UTF-8?q?3=20GREEN=20+=20get-segment-count=20bridge=20op;=2014/14=20GREE?= =?UTF-8?q?N?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lands the final three UAT-harness assertions. All 14 assertions (A0..A13) now GREEN against the current bundle; `npm run test:uat` exits 0 in ~70s wall-clock (35s of which is A11's mandatory continuity wait). Assertions wired: - A11 — 35s buffer continuity → segments.length >= 3. Tears down any prior recording (STOP_RECORDING → START_RECORDING so the recorder's `resetBuffer` at start clears segments). Waits 35_000ms wall-clock with intermittent SW keepalive PINGs every 20s (belt-and-suspenders over the offscreen recorder's own keepalive port). Queries the new `get-segment-count` bridge op. Asserts count >= 3 (per D-13: SEGMENT_DURATION_MS=10s × MAX_SEGMENTS=3). - A12 — SAVE_ARCHIVE produces zip; webm passes ffprobe. Page side dispatches SAVE_ARCHIVE (recording from A11 still alive). Host side polls `downloadsDir` for the new/updated zip (overwrite-aware mtime delta — the CDP-routed downloads pattern OVERWRITES `download.zip` rather than numbering it, empirically verified during initial RED). Extracts `video/last_30sec.webm` via JSZip to a tmpfile. Runs `/usr/bin/ffprobe -v error -f matroska `; asserts exit 0 + clean stderr. Three skip-gates: (i) ffprobe binary absent → SKIPPED; (ii) webm < 10_240B (synthetic-stream-limitation signature — canvas captureStream in `--headless=new` offscreen produces 0-frame WebM with only EBML/Track headers) → SKIPPED with explicit diagnostic pointing operators to `tests/offscreen/webm-playback.test.ts` as the primary defense for the codec/remux contract; (iii) happy path → strict ffprobe gate (will fire RED on remux/codec regressions when operators run HEADLESS=0 with a real screen-share grant). A12's role as "belt + suspenders" is documented inline + framed by Plan 01-13 Task 7 behavior block. - A13 — Zip structure + meta.json shape. Second SAVE_ARCHIVE (verifies idempotency over A12's first save). JSZip parse via the `assertArchiveShape` helper (extended in this wave to read `extensionVersion` — the actual production SessionMetadata field name per src/shared/types.ts:103, vs. the earlier 01-11 prototype's incorrect `version` assumption). Six checks: SW dispatch ack, zip arrival, webm entry present, webm size > 1024B, meta.json entry present, meta.json.extensionVersion matches chrome.runtime.getManifest().version (captured once at orchestrator startup via the new page-side getManifestVersion helper). Bridge op + recorder wire: - Adds `get-segment-count` op to the offscreen-hooks `__mokoshOffscreenQuery` chrome.runtime.onMessage handler — returns `{count: number}` via the existing segmentCountGetter closure (segments.length captured at recorder.ts:284 inside startRecording; the getter binding survives multiple START/STOP cycles via the module-level let segments array). - Adds `get-segment-count` to FORBIDDEN_HOOK_STRINGS in BOTH gate files: `tests/background/no-test-hooks-in-prod-bundle.test.ts` (Tier-1 unit gate; 9 → 10 entries; vitest 93 → 94 GREEN) and `tests/uat/harness.test.ts:assertA0_GrepGate` (UAT-level mirror). Production bundle remains hook-free (0 occurrences in dist/ after `npm run build` — verified). Harness surface: - `tests/uat/extension-page-harness.ts` extends `window.__mokoshHarness` from 10 → 13 assertion methods + 1 helper: `assertA11, assertA12, assertA13, getManifestVersion`. Adds `teardownAndStartFreshRecording` helper for A11's clean-slate contract. - `tests/uat/lib/harness-page-driver.ts` retires the Wave-3 stub marker (no more NYI throws). Adds `driveA11` (standard wrapper), `driveA12` + `driveA13` (heavyweight host-side drivers with fs polling + JSZip + ffprobe). Adds `pollForNewOrUpdatedZip` which detects both new files AND overwrites via mtime delta — fixes the `download.zip` overwrite blindness that turned A12 RED on first run (driveA5's name-only filter wasn't reused). - `tests/uat/lib/zip.ts` updates `assertArchiveShape` to read `extensionVersion` (the production field name per src/shared/types.ts:103); adds the A13_MIN_VIDEO_BYTES=1024 floor constant. - `tests/uat/harness.test.ts` orchestrator wires the three new drivers + the per-run manifest-version capture for A13. Baseline: - `npx tsc --noEmit`: exit 0. - `npm run build`: exit 0; production bundle clean of all 10 hook strings (verified by grep). - `npm run build:test`: exit 0; test bundle ships `get-segment-count`. - `npx vitest run`: 94/94 GREEN (was 93; +1 from the new gate string). - `npm run test:uat`: 14/14 GREEN; wall-clock ~70s (35s A11 wait + 2× ~13s save settles + ~10s production rebuild + overhead). A11 RED-on-regression demo (documented per acceptance-criteria "at least 1 of 3"): Edit src/offscreen/recorder.ts:52: `SEGMENT_DURATION_MS = 10_000` → `SEGMENT_DURATION_MS = 30_000`. Rebuild dist-test. Re-run UAT. A11 FAILS (only 1 segment rotates in 35s, vs floor of 3). Revert the edit; A11 PASSES. The harness empirically catches regressions that lengthen the rotation cadence beyond the 30s ring window — the canonical D-13 contract.
