Plans cover the post-D-13 architecture and the auto-start UX charter
expansion that landed during 2026-05-16 UAT:
- Plan 01-08 — WebM remux via ts-ebml@3.0.2 + webm-muxer@5.1.4. Replaces
the broken file-concat in mergeVideoSegments with a real single-EBML
remux. Drives the 2 RED tests in tests/offscreen/webm-playback.test.ts
to GREEN. Regenerates the canonical fixture against the remuxer.
5 tasks (4 TDD + 1 operator empirical checkpoint), wave 1.
- Plan 01-09 — Whole-desktop constraint (displaySurface:'monitor',
cursor:'always') + post-grant validation, chrome.action.onClicked
direct toolbar invocation, chrome.action badge state machine
(REC/OFF/ERROR), chrome.runtime.onStartup notification + recovery
notification on onUserStoppedSharing, popup scoped to SAVE-only.
17 new test assertions across 4 test files. smoke.sh updated to
auto-select an entire screen. 5 tasks (4 TDD + 1 operator empirical
checkpoint), wave 2 (depends on 01-08).
- Plan 01-10 — chrome.runtime.onInstalled welcome tab on first install
via chrome.storage.local guard; vanilla welcome.html/ts/css bundle
with single "Начать запись" button consuming install-time activation.
Uses centralized Logger pattern. 4 tasks (3 TDD + 1 operator empirical
checkpoint), wave 3 (depends on 01-09).
CONTEXT.md amendment block appended with 4 disambiguated decisions:
- D-14-remux: WebM remux supersedes D-13 file-concat
- D-15-display-surface: whole-desktop + cursor visibility lifted from
Phase 5 deferral
- D-16-toolbar: toolbar onClicked + popup SAVE-only + badge state
machine + onStartup/recovery notifications
- D-17-onboarding: welcome tab on first install (distinct from
D-17-port-lifecycle from Option C)
The earlier D-17 port-lifecycle heading also renamed to hyphenated
form for cross-ref consistency.
Plan-check loop: 3 iterations (initial + 2 revisions). Iteration 1
surfaced 11 findings (2 BLOCKER + 6 WARNING + 3 INFO); all addressed
via revision iter 1 with checker-recommended fixes. Iteration 2
surfaced 3 derivative regressions (literal-string grep anchors from
the iter-1 fixes did not match live CONTEXT.md); all addressed in iter
2 with empirically-validated literals. Iteration 3 PASSED clean.
Validation: gsd-sdk frontmatter.validate + verify.plan-structure both
return valid=True for all 3 plans. Plan 01-08 Task 4 verify-chain
grep tested end-to-end against live CONTEXT.md (exit 0).
