+# Phase 4 Verification — Harden + Clean Up (Final v1 Milestone)
+
+**Verdict: ACHIEVED.** All 4 ROADMAP success criteria CLOSED; all 3 audit P1 polish items VERIFIED; 6 cross-cutting hardening items GREEN; 3 visual-polish + flake-stabilization items VERIFIED; UAT harness 33 → 36 GREEN; vitest 184 → 188 GREEN; 6/6 pre-checkpoint bundle gates PASS; Tier-1 FORBIDDEN_HOOK_STRINGS unchanged at 12; NEW Tier-2 leak gate added; 3 /gsd-debug sessions documented; 1 operator-empirical ack received 2026-05-26.
+
+## Goal (verbatim, ROADMAP.md + PROJECT.md)
+
+Eliminate the P1/P2 follow-ups identified in the audit so that the codebase is not just spec-conformant but maintainable. This phase has no new v1 requirements — it improves robustness and removes technical debt around already-shipped behaviour. Final v1 milestone phase; Phase 4 is the last phase per the 4-phase ROADMAP.
+
+## Per-Requirement Scorecard
+
+Phase 4 has NO new REQs (all v1 REQs are covered by Phases 1-3). The scorecard below verifies the 4 ROADMAP Success Criteria + the 3 audit P1 polish items + the cross-cutting hardening items.

+## Operator-Empirical Acks (verbatim + commit refs)
+
+| Date | Plan | Operator response (verbatim) | Commit |
+|------|------|-------------------------------|--------|
+| 2026-05-26 (cycle-1) | 04-06 Task 4 | TWEAK verdict — dark cascade flipped icon to ink-900 (indigo on madder; lower contrast than light theme); routed via /gsd-debug per `feedback-gsd-ceremony-for-fixes.md` | (no commit; verdict only — followed by debug session at `.planning/debug/resolved/04-06-dark-mode-mark-decouple.md`) |
+| 2026-05-26 (cycle-2) | 04-06 Task 4 | **"Confirmed fixed — close Plan 04-06"** | `a8bcc17` (debug-fix: --mks-mark-stroke brand-component token decoupling + A35.5 light+dark equality sub-check) → operator re-empirical CONFIRMED FIXED |
+
+The Plan 04-06 Task 4 operator-empirical cycle is the canonical Phase 4 operator-empirical case per `feedback-trust-harness-over-manual-uat.md` saved memory — aesthetics judgment (dark-mode contrast) is the genuinely-non-automatable case; A35.5 decouple-proof is the automated regression coverage; operator-empirical screenshot harness at scripts/04-06-welcome-hero-screenshots.mjs is the reproducible aesthetic-judgment surface. The TWEAK → fix → CONFIRMED FIXED arc is the canonical example of why D-P4-03 was scoped as `autonomous: false`.
+
+## /gsd-debug Session Inventory (3 sessions during Phase 4)
+
+Phase 4 routed 3 /gsd-debug sessions per the `feedback-gsd-ceremony-for-fixes.md` saved memory (no hot-edits; all bugs found during execution route through ceremony):
+
+### Session 1+2: Canvas-throttling investigation (Plan 04-04 SPIKE FAILED → REFUTED-architecture)
+
+- **Session 1** (`.planning/debug/sw-offscreen-persistence-investigation.md`; commit `d614462`): INCONCLUSIVE verdict (4 competing hypotheses for the 8505-byte deterministic result; recommended ~75 min cheap disambiguation plan: Step A fix offscreen target filter + re-run + capture logs; Step B segment-count probe pre-kill; Step C spike without worker.close())
+- **Session 2** (`.planning/debug/sw-offscreen-persistence-investigation-session-2.md`; commit `4ea1bbb`): **REFUTED-architecture verdict** (HIGH confidence); 3 independent spike runs converge on the same conclusion. Root cause = canvas.captureStream invisible-canvas throttling (Chrome bug 653548 + chromium auto-throttled-screen-capture design doc); offscreen-RAM segments survive SW kill structurally (POST-KILL probe count=3; Step C variant identical 8505 bytes WITHOUT worker.close() — kill irrelevant); direct Remux logs: `Segment ts=1..3: 0 frames, duration=0ms, trackInfo=320x180`; `Remux complete: 0 frames, total timeline=0ms, output=8505 bytes`.
+- **Test-infra fix** (commit `9ac5808`): race-tolerant offscreen target attach at tests/uat/lib/launch.ts:225 (background_page → page, with full settle-and-retry; URL-pattern matching is load-bearing, type-based discrimination unreliable across event timings); permanent test-infra improvement.
+- **Recommendation**: do NOT proceed with IndexedDB persistence plan-fix; reframe SC#1 verification methodology (real getDisplayMedia in non-headless Puppeteer; OR video-file-backed fake stream that survives headless throttling). Plan 04-08 implements the video-file-backed methodology.
+
+### Session 3: Plan 04-06 dark-mode mark decoupling
+
+- **Session** (`.planning/debug/resolved/04-06-dark-mode-mark-decouple.md`; status: awaiting_human_verify → resolved at plan closure): operator-empirical Task 4 checkpoint returned TWEAK NEEDED — decouple welcome-hero mark stroke from `--mks-fg-inverse` (semantic token, flips with theme) via a dedicated `--mks-mark-stroke` brand-component token that stays linen-50 in BOTH light and dark themes.
+- **Root cause**: abstraction error. `--mks-fg-inverse` is a SEMANTIC text-foreground-on-inverse-surface token (linen-50 in light, ink-900 in dark via `.dark` override). The welcome-hero mark sits on a theme-INDEPENDENT madder-600 circle — so coupling its stroke to a theme-flipping token was the wrong abstraction.
+- **Fix** (commit `a8bcc17`): introduced NEW brand-component token `--mks-mark-stroke = var(--mks-linen-50)` in `src/shared/tokens.css` universal `:root` block (CRUCIALLY NOT overridden in `.dark, [data-theme="dark"]`); rewired `.welcome-hero__mark { color: var(--mks-mark-stroke); }` at `src/welcome/welcome.css:72`; introduced A35.5 light+dark equality decouple-proof sub-check at `tests/uat/lib/harness-page-driver.ts` via extracted `a35Probe(welcomePage, dark)` helper. Both themes now resolve `computedStroke` to `rgb(250, 247, 241)` (linen-50) — crisp linen-on-madder in both themes. SVG remains untouched (currentColor cascade plumbing identical; only wrapper's color source changed).
+- **Operator re-empirical** 2026-05-26: "Confirmed fixed — close Plan 04-06".
+- **Pattern encoded**: brand-component tokens for theme-independent surfaces; semantic tokens for theme-flipping surfaces.
+
+### Session 4: A33.1 SAVE-ack race (commit 7e0da63)
+
+- A33.1 was hard-gating on the best-effort MV3 sendMessage ack, which races after `worker.close()` (the woken SW runs the slow `saveArchive()` while the response port times out before the new instance resolves the callback). This is a known MV3 race pattern (`The message port closed before a response was received`).
+- **Fix** (commit `7e0da63`): A33.1 now gates on the race-free fresh-archive-on-disk signal (reusing `snapshotExistingZips` + `pollForNewOrUpdatedZip` from driveA12/A13/A27). Not a production bug; harness-coordination bug. A33.2/A33.3 substantive checks ALWAYS PASSED (1.56 MB video buffer survived SW kill structurally).
+- **Routing**: tracked as STATE.md Blocker (from Plan 04-05 SUMMARY Issues Encountered); resolved separately per `feedback-gsd-ceremony-for-fixes.md`.
+
+## D-P4-* Charter Closures (5/5 GREEN)
+
+| Charter | Scope | Plans | Closure |
+|---------|-------|-------|---------|
+| **D-P4-01** (Full Phase 4 scope) | All 4 ROADMAP SC + meaningful subset of 12 deferred items from 03-VERIFICATION.md; exclusions: rrweb v2 + programmatic SW-RAM; estimated 6-8 plans | Plans 04-01 through 04-08 (8 plans incl. inserted 04-08) + 3 /gsd-debug sessions | **CLOSED** via the 8 plans + 3 debug sessions; estimate 6-8 plans → actual 8 plans (within range) |
+| **D-P4-02** (Audit P1 #11+#14+#15 — all three) | Address all three audit P1 correctness items (single dedicated plan or two cohesive plans) | Plan 04-01 (single dedicated TDD plan) | **CLOSED 2026-05-21** via Plan 04-01 (commits `3dbc51c` + `7da30af`) — 3/3 P1 polish items CLOSED |
+| **D-P4-03** (Both visual polish items: cursor + dark-logo) | Cursor visibility verification + dark-surface logo contrast | Plan 04-06 (cursor verification + decoupling fix) | **CLOSED 2026-05-26** via Plan 04-06 (commits `f0b88d4` → `c790c6a` end-to-end) — both items CLOSED; multi-iteration ceremony with operator-empirical confirmation |
+| **D-P4-04** (Alpha tester out-of-band) | Alpha-tester findings routed via user's separate channels; Phase 4 proceeds independently | (honored throughout Phase 4) | **HONORED** throughout Phase 4 (no alpha-tester findings routed inline; user-handled per 2026-05-20 ack 'no no, if something i'll tell you') |
+| **D-P4-05** (ROADMAP backfill in scope) | Plans 01-08..01-13 inline-tracked but not row-added per Plan 01-13 plan-checker flag #4 | This Plan 04-07 (verification step) | **CLOSED** — Plans 01-08..01-14 rows verified present in ROADMAP.md lines 90-96; all `[x]` with closure annotations; no row additions needed (PATTERNS.md mapping holds) |
+
+## ROADMAP backfill verification (D-P4-05)
+
+Plan 01-13 plan-checker flag #4 noted that Plans 01-08..01-13 were inline-tracked in STATE.md decisions/context but may not have row-added in the ROADMAP.md Phase 1 plan-row block. Per the actual file inspection:
+
+| Plan | ROADMAP.md row present? | Line |
+|------|-------------------------|------|
+| 01-08 | YES — `[x]` with closure annotation | 90 |
+| 01-09 | YES — `[x]` with closure annotation + cycle-2 closure cross-ref | 91 |
+| 01-10 | YES — `[x]` with cycle-2 operator ack + 5 inter-cycle debug fixes annotation | 92 |

+
+**Verified — no row additions needed; plan-checker flag #4 CLOSED via this Plan 04-07.** The rows were added during Phase 1 plan closures (Plans 01-08..01-14 each emitted ROADMAP edits per their respective SUMMARY commits) and have been canonical since.
+
+## Per-Phase Plans Across Phases 1-4
+
+| Phase | Plans | Total Plans | Cumulative UAT | Cumulative vitest |
+|-------|-------|-------------|----------------|-------------------|
+| Phase 1 (Stabilize video pipeline) | 14 (01-01..01-14) | 14 | 24/24 GREEN | 153/153 GREEN |
+| Phase 2 (Stabilize export pipeline) | 4 (02-01..02-04) | 18 | 29/29 GREEN | 171/171 GREEN |
+| Phase 3 (SPEC §10 smoke + DOM/event-log verification) | 5 (03-01..03-05) | 23 | 33/33 GREEN | 171/171 GREEN |

+
+**Phase 4 contribution: +8 plans, +3 UAT assertions, +17 vitest tests, 3 /gsd-debug sessions, 1 operator-empirical ack, 4/4 ROADMAP SC closed, Tier-2 leak gate added.**
+
+## Threat Surface Scan
+
+Phase 4 introduced no NEW production-bundle security-relevant surface beyond what was already canonical in Phases 1-3. The closures (Plan 04-01 surgical edits in src/content/index.ts; Plan 04-02 build/CSP hygiene; Plan 04-03/04-05/04-06/04-08 harness extensions; Plan 04-04 SPIKE FAILED with zero source-code changes) ride existing production surfaces or modify test-only artifacts.
+
+**Plan 04-08 added a NEW test-only asset surface** (`tests/uat/fixtures/synthetic-display-source.webm` + `*.webm?url` Vite import + `assets/*.webm` web_accessible_resources entry in manifest.json). Production tree-shake via `__MOKOSH_UAT__` keeps the asset out of `dist/` entirely (Tier-2 gate at `tests/background/no-test-hooks-in-prod-bundle.test.ts` verifies 0 hits of `synthetic-display-source` literal in `dist/`). The WAR entry is inert in production (production dist/ has zero `*.webm` files; `find dist -name '*.webm' | wc -l = 0`).
+
+**No `## Threat Flags` section.** All threat-register dispositions from each plan's `<threat_model>` block were honored (mitigate / accept dispositions; threat IDs T-04-01-*..T-04-08-*).
