  reconciliation (dist/src/offscreen/index.html), full dist layout
  for Plan 07's smoke test, T-1-NEW-06-01 / T-1-NEW-06-02 grep gates
- STATE.md: completed_plans 5 → 6, percent 71 → 86, current plan
  advanced 6 → 7, two new decisions logged, session stopped_at updated
- ROADMAP.md: Phase 1 plan progress row 4/7 → 6/7; 01-06-PLAN.md

 - [Phase ?]: [Phase 01-05]: SW is now a pure coordinator — onConnect host bound to 'video-keepalive' port with T-1-04 sender check; getVideoBufferFromOffscreen replaces synchronous SW-local buffer fetch; OFFSCREEN_READY handshake closes the audit P1 #12 race
