BLOCKING CONSTRAINTS — Read Before Anything Else

These persist from prior sessions and were reaffirmed this session:

• CONSTRAINT: No unilateral scope reduction — auto-memory feedback-no-unilateral-scope-reduction.md. Surface options via AskUserQuestion or default to FULL scope; never pre-narrow. Apply this to BOTH orchestrator AND when briefing subagents (subagents must not surface their own context anxiety as user-facing decisions).
• CONSTRAINT: GSD ceremony for fixes — auto-memory feedback-gsd-ceremony-for-fixes.md. Route bugs through /gsd-debug; orchestrator does not hot-edit src/.
• CONSTRAINT: Pre-checkpoint bundle gates — auto-memory feedback-pre-checkpoint-bundle-gates.md. Before surfacing any operator empirical checkpoint, run: SW CSP grep (new Function/eval), SW Node-globals grep (Buffer.from), Tier-1 SW-bundle-import gate (tests/background/sw-bundle-import.test.ts), manifest validation. Failure = route to /gsd-debug, NOT to operator.

Acknowledge each before proceeding.

Recurring anti-pattern this session

Subagent context-anxiety surfacing — gsd-executor at 66% and gsd-debug-session-manager at 72% both surfaced "should I split / pause" as user-facing decisions despite explicit anti-context-anxiety directives in their spawn prompts. The saved memory covers orchestrator-side surfacing; subagent-side surfacing needs stronger handling. For next session: when spawning subagents, include explicit failure-path instructions ("if you genuinely run out: commit clean stopping point + return; orchestrator handles failover via fresh executor — do NOT pause for user decision").

Current State

Phase 01 is mid-Wave-2 (Plan 01-09 closeout):

• Plan 01-08 (WebM remux): DONE. Resolved via 2-stage fix — resolve.alias for ebml CJS-main + vite-plugin-node-polyfills Buffer polyfill. Commits 5035314..e40949d. Tier-1 SW-bundle-import gate landed (tests/background/sw-bundle-import.test.ts, 2 layers).
• Plan 01-09 Tasks 1-4: DONE in code. Commits 333e0dc..c711d7e. 17 new tests GREEN. 81/81 vitest GREEN. tsc clean. Build exit 0.
• Plan 01-09 Task 5 operator empirical: SURFACED 2 BUGS:
  • Bug A (icon files corrupt placeholders): unblocked via auto-generated placeholders in working tree (uncommitted). icons/icon{16,48,128}.png at 574/1153/2615 bytes — all above Chrome notification API minimums.
  • Bug B (setErrorMode locks operator out): state machine routes user-stopped-sharing → setErrorMode → popup stays SAVE-only → toolbar.onClicked won't fire → operator has no restart UI path. Plus recovery notification failed due to Bug A. Operator perception: "recording never stops."
• Design intel committed: .planning/intel/design-system.md + assets-spec.md (commit 949aa03). Designer-team handoff specs.
• D-13 trade-off confirmed: operator reports "some seconds missing in tail." Documented architectural trade-off, NOT a Plan 01-09 regression. Defer to Phase 5 hardening (sub-second rotation OR in-flight inclusion with synthetic Matroska finalization).

Test/build baseline at pause:

• 81/81 vitest GREEN
• Tier-1 SW-bundle-import gate (Layer 1 + Layer 2) GREEN
• tsc clean
• npm run build exit 0
• Working tree has 5 uncommitted: STATE.md (auto-modified), 3 icon placeholders, tests/fixtures/last_30sec.webm (probably needs revert — verify against HEAD)

Plan 01-10

Pending. Wave 3. depends_on: [01-09]. PLAN.md exists at .planning/phases/01-stabilize-video-pipeline/01-10-PLAN.md. Unblocked once 01-09 closes.

Next-session order of operations

1. /gsd-resume-work to load HANDOFF.json.
2. Verify uncommitted files state: git diff tests/fixtures/last_30sec.webm — if it differs from HEAD (which it probably does because operator's smoke regenerated it), revert: git checkout HEAD -- tests/fixtures/last_30sec.webm. The Plan 01-08 fixture committed at e40949d is the canonical one.
3. Commit icon placeholders (Bug A unblock):

   git add icons/icon{16,48,128}.png
   git commit -m "fix(01-09): Bug A — auto-generated icon placeholders unblock notification API"
   

4. Spawn fresh /gsd-debug session for Bug B with explicit anti-context-anxiety directive in the prompt. Use this prompt skeleton:
   • slug: 01-09-recovery-flow
   • Bug B specifics: route src/background/index.ts:725-744 RECORDING_ERROR handler on message.error code — 'user-stopped-sharing' → setIdleMode(); other codes → setErrorMode() (preserved).
   • All 3 hypotheses already empirically verified (per prior session manager's checkpoint return); fresh session can skip verification phase and go straight to RED test + GREEN fix.
   • RED test belongs in tests/background/badge-state-machine.test.ts (extend with routed-error-code case).
5. Pre-checkpoint gates (per saved memory) BEFORE re-surfacing operator UAT.
6. Operator UAT re-run to confirm Bug A + Bug B fixed.
7. Wave 3: /gsd-execute-phase 1 continues to Plan 01-10.
8. /gsd-verify-work 1 goal-backward.
9. Phase 1 closure markers flip: REQUIREMENTS.md [ ] → [x], ROADMAP [ ] → [x], STATE.md phase_reopened → phase_complete.

Required reading (in order)

1. .planning/HANDOFF.json — structured state
2. .planning/intel/design-system.md + .planning/intel/assets-spec.md — design specs for designer team
3. src/background/index.ts lines 54 (NOTIFICATION_ICON_PATH), 85-108 (state machine), 725-744 (RECORDING_ERROR handler — fix target), 833-840 (startup notification)
4. src/offscreen/recorder.ts lines 451-480 (onUserStoppedSharing — confirms resetBuffer happens)
5. .planning/phases/01-stabilize-video-pipeline/01-09-PLAN.md — full Plan 01-09 spec
6. tests/background/badge-state-machine.test.ts — RED test target for Bug B

Infrastructure state

• Branch: gsd/phase-01-stabilize-video-pipeline, currently at 949aa03 (head)
• vite.config.ts has Buffer polyfill + ebml alias (Plan 01-08 critical fixes; do not touch)
• smoke.sh has timer overlay (commit 923aaca) AND SHARE_TARGET="Entire screen" (Plan 01-09); preserve both
• manifest.json has notifications permission (Plan 01-09)
• Tier-1 SW-bundle-import gate is the automation contract for ALL future bundle-touching changes
