   - **No stale storage-state** (Pitfall 14): use `DEV_AUTH_BYPASS=true` for the automated harness rather than a checked-in storage-state.json with an expiring session cookie; decide the auth strategy before the first test.
   - **Service worker block** (Pitfall 15): set `serviceWorkers: 'block'` (or explicitly unregister) in the context so a previous run's SW does not intercept requests / return stale cached responses; verify no SW-sourced responses in the trace.
   - Hard constraints: targets the dev build via `DEV_AUTH_BYPASS` (DEV_AUTH_BYPASS user 1 has no CalDAV credential/calendars — verify layout/flows, not live event-create); real prod-service-worker / iOS-Safari-standalone mobile testing stays a human/device gate (out of scope).

+- [ ] 07-01-PLAN.md — Harness foundation: @playwright/test + WebKit/Chromium browsers, playwright.config.ts (iPhone/WebKit + Pixel/Chromium matrix, serviceWorkers block, env baseURL, vite webServer), vitest exclude, scripts (Wave 1)
+- [ ] 07-02-PLAN.md — global-setup.ts: /health readiness poll + deterministic mysql2 reset-and-seed (calendar id 10 INSERT IGNORE guard, list + items) + e2e README/guardrails (Wave 2)
+- [ ] 07-03-PLAN.md — layout.spec.ts: tap targets >=44px, no overflow, in-viewport, accessible names (UI-SPEC Rules 1-4) + harness self-validation injected-defect proofs (Wave 3)
+- [ ] 07-04-PLAN.md — calendar.spec.ts + lists.spec.ts: populated/empty/error states (Rules 4/5) + DEV_AUTH_BYPASS auth-reached + no-SW-controller precondition (Wave 3)
