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
01-11	YES — [x] with PIVOTED to 01-13 annotation	93
01-12	YES — [x] with operator brand-fit ack annotation	94
01-13	YES — [x] with Plan 01-09 functional closure annotation	95
01-14	YES — [x] with Chrome 119+ picker enhancement annotation	96

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 (Harden + clean up)	8 (04-01..04-08, including inserted 04-08)	31	36/36 GREEN	188/188 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-).

Closure Statement

Phase 4 ACHIEVED its goal. All 4 ROADMAP success criteria CLOSED; all 3 audit P1 polish items VERIFIED; 6 cross-cutting hardening items GREEN; 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 (Plan 04-08); 3 /gsd-debug sessions documented + resolved; 1 operator-empirical ack received 2026-05-26.

This 04-VERIFICATION.md is the executor-created aggregator. Per the canonical Phase 1-3 precedent, an independent gsd-verifier audit runs after Plan 04-07 closure to perform the goal-backward audit and elevate Phase 4 to the formally-CLOSED state. After the verifier audit passes, the orchestrator flips:

• ROADMAP.md Phase 4 row [ ] → [x] with CLOSED date + verifier audit cite
• STATE.md progress.completed_phases: 3 → 4 + progress.percent: 93 → 100 + status: executing → completed
• Subsequent v1.0 tag + release notes (alpha redistribution per D-P4-04 charter — out-of-band; user-routed)
