# 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):
   ```bash
   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
