# BLOCKING CONSTRAINTS — Read Before Anything Else

> These are not suggestions. Each constraint below was discovered through failure in the prior session.
> Acknowledge each one explicitly before proceeding.

- [ ] **CONSTRAINT: Context-anxiety-driven scope reduction** — Do NOT surface harness hook "CONTEXT WARNING" messages to the user. Do NOT narrow scope based on extrapolated context budget. Do NOT conflate subagent context (200K) with orchestrator context (1M). The user validates every quality-driven change themselves; pre-filtering is the wrong default for this project. The auto-loaded memory `feedback-no-unilateral-scope-reduction.md` has the full rule including the context-anxiety sub-rule.

- [ ] **CONSTRAINT: Hot-edits bypassing GSD ceremony** — Do NOT call Edit/Write on `src/` files in response to bugs discovered during execute/verify. Route through `/gsd-debug` for investigation → RED test landed → `gsd-executor` agent for the fix. The auto-loaded memory `feedback-gsd-ceremony-for-fixes.md` has the full rule.

**Do not proceed until both boxes are checked.**

## Critical Anti-Patterns

| Pattern | Description | Severity | Prevention Mechanism |
|---------|-------------|----------|---------------------|
| Context-anxiety scope reduction | I'm on Opus 4.7 with 1M context; 30% remaining = ~300K tokens. The harness fires "CONTEXT WARNING at 65/67/70%" hooks calibrated for typical models — they are advisory infrastructure, not user voice. Treating them as user-binding led me to (a) pick "CR-only" unilaterally from a 3-option checkpoint without asking and (b) repeatedly surface hook messages to the user as if they were decisions to make. | blocking | Memory `feedback-no-unilateral-scope-reduction.md` is auto-loaded. The explicit rule: any time about to type "context is tight" / "this might exhaust context" / "let me ask whether to pause" — STOP and just continue work. Compact silently if needed. Never surface a harness hook to the user as a user-facing choice. |
| Hot-edits bypass GSD ceremony | When the D-12 bug surfaced (75-byte WebM), I started calling Edit on `src/shared/types.ts` to fix it inline. User correctly stopped me — fixes route through `/gsd-debug` → RED test → `gsd-executor`, not orchestrator hot-edits. | blocking | Memory `feedback-gsd-ceremony-for-fixes.md` is auto-loaded. Trigger: any Edit/Write on `src/` inside an execute/verify context in response to a checkpoint failure — STOP, route through `/gsd-debug` or proper plan-fix. |
| Pre-staged HIGH-risk fallback activation pattern | Both D-12 (base64 wire) and D-13 (restart-segments) pre-staged fallbacks from CONTEXT.md activated as designed when ffprobe + playback gates surfaced. Strong evidence the pre-staging strategy works. | advisory | No prevention needed — this is good behavior. But worth a GSD-framework retro item: should `/gsd-plan-phase` auto-inject empirical-acceptance gates (ffmpeg dry-run, Chrome playback) BEFORE phase close when RESEARCH.md flags HIGH-risk assumptions? See `01-07-SUMMARY.md` process-observation tail. |

<current_state>
Phase 1 is **functionally complete**:
- REQ-video-ring-buffer marked Complete in REQUIREMENTS.md
- ROADMAP.md Phase 1 row marked Complete (2026-05-15)
- SPEC §10 #7 satisfied (operator-confirmed clean Chrome playback + ffmpeg dry-run exit 0)
- 30/30 unit tests pass; tsc clean; `npm run build` succeeds
- Branch: `gsd/phase-01-stabilize-video-pipeline` (clean working tree)
- Two debug sessions resolved (`.planning/debug/resolved/d12-blob-port-transfer-fails.md`, `.planning/debug/resolved/webm-playback-freeze.md`)
- Phase 1 code review (deep depth) done — `01-REVIEW.md` (3 Critical + 9 Warning + 6 Info = 18 findings)
- Review fix **PARTIAL**: 5/18 landed in commit `2e3f524` (CR-01 + CR-02 + CR-03 + WR-03 + WR-09). 13 remain + 8 sweep targets discovered during review.

What's left: finish remaining review fixes, run verifier, start Phase 2.
</current_state>

<completed_work>

**Plans (all 7):**
- Plan 01-01: Doc cascade D-A1..D-A6 + manifest swap — commit `13b67f5`
- Plan 01-02: Vitest + 4 RED test files — commit `edc605d`
- Plan 01-03: `src/offscreen/recorder.ts` TDD GREEN (getDisplayMedia + ring buffer + codec strict-mode) — commit `30e5efd`
- Plan 01-04: Port keepalive + OFFSCREEN_READY handshake (TDD) — commit `05d0050`
- Plan 01-05: SW shrink + port host (T-1-04 sender-id check on both ends) — commit `9e236cb`
- Plan 01-06: Build pipeline collapse (vite.config 226 → 21 LoC; deleted orphan `offscreen/` dir) — commit `1ebfb42`
- Plan 01-07: Manual smoke + ffprobe gate + playback acceptance (3 attempts; closure commit `1d06d9d`)

**Debug sessions (both resolved):**
- `d12-blob-port-transfer-fails` (5 commits `c0d9166..bf07619`): base64 wire format for port messages; Blobs were collapsing to "[object Object]" through chrome.runtime port JSON serialization
- `webm-playback-freeze` (6 commits `5530292..872f25d`): D-13 restart-segments activation; retired D-09..D-11 single-continuous + age-trim + first-chunk-pin

**Code review + partial fix:**
- `01-REVIEW.md` committed
- `01-REVIEW-FIX.md` partial (`checkpoint: true`); 5/18 fixes landed in commit `2e3f524`
</completed_work>

<remaining_work>

**Priority 1 — Finish review fixes (`/gsd-code-review-fix 1`):**
13 review findings + 8 sweep targets remain. ALL documented in `.planning/phases/01-stabilize-video-pipeline/01-REVIEW-FIX.md` "Remaining Work" section with file:line + intended fix per item.

Remaining labeled findings:
- 7 Warning: WR-01, WR-02, WR-04, WR-05, WR-06-defer, WR-07, WR-08
- 6 Info: IN-01, IN-02, IN-03, IN-04, IN-05, IN-06
- 8 sweep targets: described in REVIEW-FIX.md remaining-work section (ranked by impact)

**Priority 2 — Phase 1 verifier (`/gsd-verify-work 1`):**
Goal-backward verification: confirm REQ-video-ring-buffer + SPEC §10 acceptance criteria are actually delivered by code (not just claimed by SUMMARYs). Per Quality settings, verifier is enabled.

**Priority 3 — Phase 2 (`/gsd-plan-phase 2`):**
Stabilize DOM + event capture privacy. Per ROADMAP §"Phase 2": REQ-rrweb-dom-buffer, REQ-user-event-log, REQ-password-confidentiality. P0 #5 from original audit (rrweb v2 maskInputFn + content-script input-logger password+data-sensitive guard).
</remaining_work>

<decisions_made>

- **Switched capture API to `getDisplayMedia()`** (amends DEC-003). Operator picks share target; Chrome shows "Sharing your screen" banner. Trade-off accepted per D-04. Manifest swap: `tabCapture` → `desktopCapture`.
- **Activated D-13 restart-segments** lifecycle. Retired D-09..D-11. Each segment is a self-contained ~10s WebM with its own keyframe; up to MAX_SEGMENTS=3 retained.
- **Base64 wire format** for port messages (`TransferredVideoSegment.data: string`). Survives chrome.runtime port JSON serialization (Blobs don't).
- **Cursor visibility refinement deferred to Phase 5** (logged in ROADMAP.md Phase 5 P1/P2 list).
- **Cleanup decision: deleted `chrome.alarms` keepalive entirely** (audit P1 #8 + amends DEC-010). Long-lived `chrome.runtime.connect` port from offscreen → SW is the real keepalive.
</decisions_made>

<blockers>
None. Working tree is clean. All next-step commands are unblocked.

## Required Reading (in order)

1. `.planning/phases/01-stabilize-video-pipeline/01-REVIEW-FIX.md` — "Remaining Work" section is the work list for `/gsd-code-review-fix 1`.
2. `.planning/phases/01-stabilize-video-pipeline/01-REVIEW.md` — original review (cross-reference for ambiguity).
3. `.planning/phases/01-stabilize-video-pipeline/01-07-SUMMARY.md` — wraps Phase 1's two-attempt journey; has the process observation about pre-staged fallback strategy.
4. `.planning/phases/01-stabilize-video-pipeline/01-CONTEXT.md` — locked decisions; especially D-01..D-A6 (now mostly retired by amendments).
5. `.planning/debug/resolved/d12-blob-port-transfer-fails.md` — Resolution section explains the JSON-serialization root cause.
6. `.planning/debug/resolved/webm-playback-freeze.md` — Resolution section explains the A3 keyframe-gap root cause + D-13 activation.
7. `.planning/STATE.md` — current state; Decisions log appended.
8. `.planning/ROADMAP.md` — Phase 1 = Complete; Phase 2 next; cursor-visibility deferral now in Phase 5 P1/P2 list.

## Infrastructure State

- **Git:** branch `gsd/phase-01-stabilize-video-pipeline` checked out in main repo. Working tree clean. ~37 commits since the initial `chore: import broken Phase-1 extension as received`.
- **Chrome smoke profile:** `/tmp/mokosh-smoke-profile/` — extension loaded; KEEP_PROFILE=1 ./smoke.sh reuses it.
- **Tests:** `npx vitest run` → 30/30 across 8 test files. `npx tsc --noEmit` clean. `npm run build` succeeds; `dist/` is current.
- **Fixture:** `tests/fixtures/last_30sec.webm` (1.6 MB VP9 1142×1038, regenerated 2026-05-15 against D-13 recorder).

## Pre-Execution Critique Required

N/A — no design artifact awaiting critique. The two pre-staged fallback skeletons (D-12 base64, D-13 restart-segments) were both activated and resolved; no orphan designs remain.

<context>
The session went from "initialize GSD on a half-broken zip" → fully GSD-tracked Phase 1 closure across discuss → plan → execute → 2 debug sessions → code review → partial code-review-fix. The user is engaged, makes substantive decisions, and pushed back hard on two things I should never repeat: (1) unilateral scope reduction when they signaled max rigor + "I validate everything", (2) hot-edits bypassing GSD ceremony. Both memories saved at `~/.claude/projects/-home-parf-projects-work-repremium/memory/`.

The MAIN unfinished thread is the 13 review findings + 8 sweep targets. They're all documented; a fresh-context `gsd-code-fixer` agent should finish them in one pass without checkpointing. After that, verifier + Phase 2.
</context>

<next_action>
Run `/gsd-resume-work` to load this handoff cleanly, then:

```
/gsd-code-review-fix 1   # finish 13 review findings + 8 sweep targets (full scope, no narrowing)
/gsd-verify-work 1       # goal-backward verifier confirms REQ-video-ring-buffer delivered
/gsd-plan-phase 2        # begin Phase 2: rrweb + event log + password masking
```

Do NOT narrow scope on the review-fix pass. The user said "Do all the problems" and pushed back twice on context-anxiety-driven narrowing in the prior session. If a subagent checkpoints offering scope options, surface the choice to the user via AskUserQuestion — do not pick for them.
</next_action>
