+# Phase 17 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+> Source: `17-RESEARCH.md` §Validation Architecture. Requirement IDs are TBD for this
+> phase (UI/UX polish + branding) — decisions D-01…D-10 (CONTEXT.md) and workstreams
+> A–D (UI-SPEC.md) stand in for REQ-IDs until promoted in plan-phase.

+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **E2E Framework** | Playwright 1.60.0 |
+| **Unit Framework** | Vitest ^4.1.8 |
+| **E2E config file** | `apps/pwa/playwright.config.ts` (profiles: `iphone` 390×844 WebKit, `pixel` 412×915 Chromium, `desktop` 1280×720) |
+| **Unit config file** | `apps/pwa/vitest.config.ts` |
+| **Quick run command** | `pnpm --filter @familysync/pwa exec playwright test --project=pixel layout.spec.ts` |
+| **Full suite command** | `pnpm --filter @familysync/pwa test:e2e` |
+| **Build gate** | `pnpm --filter @familysync/pwa build` |
+| **Estimated runtime** | ~45–90 seconds (quick: ~15s; full 3-profile suite: ~60–90s) |
+| **Browser-verification skill** | `playwright-cli` (desktop/Chromium UI checks the spec suite cannot cover) |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** Run `pnpm --filter @familysync/pwa exec playwright test --project=pixel layout.spec.ts` (phone profile covers the primary fix geometry)
+- **After every plan wave:** Run `pnpm --filter @familysync/pwa test:e2e` (full 3-profile suite) + `pnpm --filter @familysync/pwa build`
+- **Before `/gsd-verify-work`:** Full Playwright suite green + playwright-cli visual sweeps passed + **human logo approval received** (Workstream B checkpoint)
+- **Max feedback latency:** ~90 seconds
+

+
+## Per-Task Verification Map
+
+> Task IDs are assigned by the planner. This map is workstream/decision-keyed; the executor
+> binds each task ID to the matching row's automated command during execution.

+
+## Wave 0 Requirements
+
+- [ ] **Overlap regression assertion** — add the FAB↔BottomTabBar geometry test to `apps/pwa/e2e/layout.spec.ts` (Workstream A; runs on iphone + pixel, skipped on desktop). Contract in UI-SPEC §"Regression guard".
+- [ ] **Admin tab ARIA assertion** — add `role="tablist"`/`role="tab"`/`aria-selected`/`role="tabpanel"` checks to `apps/pwa/e2e/admin.spec.ts` (or append to `layout.spec.ts`) (Workstream D-10).
+- [ ] **Asset existence check** — Wave 0 npm script or inline CI step asserting all 7 `apps/pwa/public/` assets exist with valid format (ICO size, maskable dimensions).
+- [ ] **`@vite-pwa/assets-generator` devDependency** — install in `apps/pwa` (pulls `sharp` + `sharp-ico`; the only new package) before Workstream B asset derivation runs.
+
+*Existing infrastructure (Playwright 3-profile config + `layout.spec.ts` Rules 1–4 + Vitest) covers the bulk of the structural assertions.*
+

+
+## Manual-Only Verifications
+
+| Behavior | Decision | Why Manual | Test Instructions |
+|----------|----------|------------|-------------------|
+| Logo / icon set meets warm/rounded/at-home brief | D-03 | Aesthetic judgment; AI-generated art needs operator sign-off | playwright-cli screenshot of BrandSlot on `/login` + favicon in tab; operator approves at checkpoint before wiring is committed |
+| Brand accent selection (cool-blue vs warm rose/amber) | UI-SPEC Q1 | Subjective brand decision | Present both variants (one-line token swap); operator selects at logo checkpoint |
+| Maskable adaptive-icon render on a real device | D-04 | iOS/Android home-screen mask is device-only (cannot be driven by playwright-cli) | Install PWA on a device, confirm logo within safe-zone (optional spot-check; format validated automatically) |
+| Schedule-X calendar colors visually unchanged post-restructure | D-06 | Visual regression of third-party calendar theme | playwright-cli sweep of `/calendar` before/after the tokens.css restructure |
+
+---
+
+## Validation Sign-Off
+
+- [ ] All tasks have an automated verify command or a Wave 0 dependency
+- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
+- [ ] Wave 0 covers all MISSING references (overlap assertion, admin ARIA assertion, asset-existence check, assets-generator install)
+- [ ] No watch-mode flags (`playwright test` / `vitest run` are one-shot)
+- [ ] Feedback latency < 90s
+- [ ] `nyquist_compliant: true` set in frontmatter
