SUMMARY.md documents:
- 3 RED tests in tests/background/blob-url-download.test.ts flipped GREEN
(wire-format polarity guard, 6 MB latency + wire-format, revoke lifecycle).
- 6 files modified (3 prod source + 3 test files; +518 / -35 lines).
- Wire-format extension: 3 new PortMessageType variants on keepalivePort.
- Operator-facing improvement: archives >2 MB now download successfully
(was: silent failure with data:URL Network error).
- Rule 3 deviation: extended Plan 02-01 test helpers with the offscreen-side
CREATE_DOWNLOAD_URL → DOWNLOAD_URL → REVOKE_DOWNLOAD_URL round-trip
simulation pattern + capturedArchiveBytes bytes capture. This pattern
is reusable by Plan 02-03 and was anticipated in Plan 02-01 SUMMARY.
- Forward link: Plan 02-03 (meta.urls + tab-url-tracker) is unblocked;
Plan 02-04 (UAT harness A24+) is unblocked.
Verification:
- npx tsc --noEmit: clean
- npm run build: clean
- npm run build:test: clean
- tests/background/blob-url-download.test.ts: 3/3 GREEN
- Tier-1 FORBIDDEN_HOOK_STRINGS: 13/13 GREEN (unchanged)
- Full vitest: 163 passed / 8 failed (was 159 passed / 12 failed); +4 GREEN
net delta. 8 remaining RED are exactly Plan 02-03 territory.
