+<objective>
+Stand up the Playwright test-harness foundation in `apps/pwa`: add `@playwright/test` as a dev dependency, install the WebKit + Chromium browser engines, author `playwright.config.ts` with the two-profile device matrix (iPhone/WebKit + Pixel/Chromium), and isolate the new `e2e/*.spec.ts` glob from the existing Vitest `*.spec.ts` default glob. This is the blocking dependency for the seed plan and all spec plans.
+
+Purpose: Every downstream plan (global-setup, layout/calendar/lists specs) imports from `@playwright/test` and runs under this config. Nothing else in the phase can land until the config matrix, browser engines, and glob isolation exist.
+
+Output: `apps/pwa/playwright.config.ts`, the `@playwright/test` dev dep + installed browsers, `vitest.config.ts` exclude, package.json scripts, and `e2e/` brought into the `tsc --noEmit` gate.

Do NOT rely on the global `playwright-cli` Chromium — the harness brings its own browser store. Add three scripts to `apps/pwa/package.json` scripts block: `test:e2e` = `playwright test`, `test:e2e:ui` = `playwright test --ui`, `test:e2e:headed` = `playwright test --headed`.

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| harness → dev API | Playwright drives the PWA which calls the API; the API runs with `DEV_AUTH_BYPASS=true` (dev only) |
+| repo → CI/production | config + scripts checked into the repo; must not leak dev-only auth posture into production |

+|-----------|----------|-----------|-------------|-----------------|
+| T-07-01 | Elevation of Privilege | `DEV_AUTH_BYPASS=true` reaching production | mitigate | Config sets no auth-bypass itself — bypass is API-side and guarded by `NODE_ENV !== 'production'` (devBypass.ts). This plan documents in the README (Plan 02/04) that production compose MUST NOT set `DEV_AUTH_BYPASS`. The harness config only assumes the dev stack already has it. |
+| T-07-02 | Information Disclosure | checked-in `storageState.json` with a real OIDC session | accept (designed out) | N/A by D-01 — `playwright.config.ts` deliberately omits `storageState`; auth comes from the dev bypass, never a session file. No session cookie is ever serialized into the repo. |
+| T-07-03 | Tampering | `@playwright/test` package install | mitigate | Pinned to 1.60.0 (official Microsoft package, 38.6M wk downloads — RESEARCH.md Package Legitimacy Audit, verdict OK/Approved). No `[ASSUMED]`/`[SUS]`/`[SLOP]` packages introduced; mysql2 (SUS-but-approved) is already a project dep and is not added here. |

+<objective>
+Create the Playwright `globalSetup` (seeding runs in global-setup per D-07) that the harness runs once before any spec: poll the PWA `/health` endpoint until the dev stack is ready (D-08 readiness gate), then deterministically reset-and-seed the dev MariaDB (D-06) so dev-bypass user 1 — who natively has no calendars or lists — renders populated calendar and list views. This is the populated half of the D-05 hybrid strategy (the explicit empty-state assertions live in Plan 04). Document the run/CI invocation and the `DEV_AUTH_BYPASS`/production guardrail.
+
+Purpose: Without seeding, user 1's views are empty and the "populated state" assertions (UI-SPEC Rules 3/5) have nothing to assert against. Without the readiness poll, specs flake on ECONNREFUSED when the stack is still booting (especially in Phase 8 CI). This is the data + readiness precondition every spec plan depends on (TEST-02).

Then the calendar_id=10 FK guard (Pitfall 4): `INSERT IGNORE INTO calendars (id, user_id, url, display_name, color, is_shared) VALUES (10, 1, 'https://caldav.fastmail.com/dav/calendars/e2e/', 'FamilySync', '#4A90D9', true)` — IGNORE makes it a no-op on the dev DB where row 10 already exists and creates it on a fresh CI DB. Then seed one TIMED (not all-day) calendar_event onto calendar_id=10 with a deterministic uid `'e2e-seed-event-001'`, title `'Seeded Test Event'`, a future `dtstart_utc` (ISO UTC string ~tomorrow), a minimal VCALENDAR/VEVENT `raw_vevent`, `etag='e2e-etag-001'`, `all_day=false`, `has_rrule=false`. Then seed one list `INSERT INTO lists (owner_id, name, is_shared) VALUES (1, 'E2E Grocery List', true)`, capture `insertId` as `listId`, then `INSERT INTO list_shares (list_id, user_id) VALUES (?, 1)` and `INSERT INTO list_items (list_id, text, checked, rank) VALUES (?, 'Milk', false, 'a0'), (?, 'Eggs', false, 'a1')`. Use fractional-indexing rank strings `'a0'`/`'a1'` (active items render top-section). Seed BOTH `lists.owner_id=1` AND a `list_shares` row (Open Question 3 — belt-and-suspenders so `/api/lists` returns the list whether it filters by owner or by share). Determinism note: because every run truncates first, a second run yields identical row counts — no INSERT IGNORE on the seed rows themselves (D-06 mandates truncate+insert, NOT insert-if-absent). The list name `'E2E Grocery List'` and item texts `'Milk'`/`'Eggs'` are the stable anchors the lists spec (Plan 04) asserts on — do not change them without updating that spec.

(3) Env vars the harness reads: `PLAYWRIGHT_BASE_URL` (default http://localhost:5173), `DB_HOST` (default 127.0.0.1), `DB_PORT`, `DB_USER`, `DB_PASSWORD`, `DB_NAME` — all DB creds come from env, NEVER hardcoded (Information Disclosure mitigation).

(5) No `storageState`: the harness never reads or writes a session-state file (D-01); there is no expiring cookie to refresh, which is why it runs repeatably day-over-day (SC #3).

+<objective>
+Author `apps/pwa/e2e/layout.spec.ts`: the cross-route structural quality-bar assertions (UI-SPEC Rules 1-4) running on both the iPhone/WebKit and Pixel/Chromium profiles (per D-03 two-profile matrix + D-04 faithful engines) with `serviceWorkers: 'block'` on each context (D-02) — tap targets ≥44px, no horizontal overflow, critical elements visible and in-viewport, accessible names present. Bake in the harness self-validation: prove each core assertion FAILS on a deliberately injected defect, then PASSES once removed. This is the proof that the harness measures rendered geometry, not CSS source (TEST-01).
+
+Purpose: These are the mobile-only defect classes the harness exists to catch (sub-44px touch targets, Schedule-X horizontal overflow). A green suite alone does not prove the assertions are live — the injected-defect proofs are the acceptance bar (07-VALIDATION.md § Harness Self-Validation).

+  </read_first>
+  <action>
+    Create `apps/pwa/e2e/layout.spec.ts` importing `test, expect` from `@playwright/test`. Tests run against BOTH projects automatically (config matrix per D-03/D-04) — write profile-agnostic specs; do not hardcode viewport widths (read `page.viewportSize()` when needed). STRICT-MODE CAVEAT: both `BottomTabBar` (phone) and `AppNav`/`PhoneNav` expose a `navigation` landmark named "Main navigation" and `link`s named "Calendar"/"Lists" — a bare `getByRole('link', { name: 'Calendar' })` may match 2 elements and throw a strict-mode violation. Scope tap-target assertions to the BottomTabBar specifically: locate the bar via its nav landmark, then query links WITHIN it (e.g. `const bar = page.getByRole('navigation', { name: 'Main navigation' }).last()` or scope by the bottom-bar container, then `bar.getByRole('link', { name: 'Calendar' })`). Confirm the correct scoping by reading BottomTabBar.tsx vs AppNav.tsx before writing the locator; if both share the exact landmark name, disambiguate by position (bottom bar is the fixed-bottom one) or add a `.last()`/filter — document the chosen disambiguation in a comment. Implement, on `/calendar` (and `/lists` where the route applies):
+    Rule 1 (tap targets, UI-SPEC table): BottomTabBar Calendar tab ≥44×44, Lists tab ≥44×44, PhoneNav settings button (`getByRole('button', { name: /open settings/i })`) ≥44×44, New Event FAB (`getByRole('button', { name: 'New Event' })`) ≥56×56 — measure via `await locator.boundingBox()`, assert non-null and width/height thresholds. (Retry button tap target is covered in the calendar error-state spec, Plan 04 — do not duplicate here.)
+    Rule 2 (overflow): on `/calendar` and `/lists`, `page.evaluate(() => ({ scrollWidth: document.documentElement.scrollWidth, clientWidth: document.documentElement.clientWidth }))`, assert `scrollWidth <= clientWidth`. No allowed exceptions (Schedule-X overflow is the defect to catch).
+    Rule 3 (in-viewport): assert the BottomTabBar nav `isVisible()` is true and its `boundingBox().y + height <= page.viewportSize()!.height` (safe-area-inset is 0 in emulation); assert the PhoneNav header is visible.
+    Rule 4 (accessible names): the fact that the Rule 1 locators resolve by role+name already proves accessible names exist; additionally assert the navigation landmark `getByRole('navigation', { name: 'Main navigation' })` is present (scoped per the caveat above). Use relative `page.goto('/calendar')` / `page.goto('/lists')` — NEVER an absolute URL (resolves against config baseURL, Rule 8).

Approach: do NOT structure these as tests that intentionally fail the suite — structure each as a single passing test that internally proves the assertion would have failed under a defect and passes after removal. For the tap-target proof: navigate to `/calendar`, inject `page.addStyleTag({ content: 'nav[aria-label="Main navigation"] a { min-height: 20px !important; height: 20px !important; }' })` (or the equivalently-scoped BottomTabBar selector), measure the Calendar tab boundingBox, assert its height is now < 44 (proving the measurement tracks the rendered box, not the source CSS). Then remove the injected style — use `page.addStyleTag` returning a handle and `handle.evaluate(el => el.remove())`, OR reload the page to drop the injected tag — re-measure and assert height ≥ 44 again. For the overflow proof: on `/calendar`, inject `page.addStyleTag({ content: 'body { width: 2000px !important; }' })`, evaluate scrollWidth/clientWidth, assert `scrollWidth > clientWidth` (defect detected), then remove/reload and assert `scrollWidth <= clientWidth` (clean). Each proof is one test that PASSES by demonstrating the fail→clean transition; the suite stays green while proving the assertions detect real defects. Keep these in the same file so they share the config matrix (run on both profiles).

+Author `apps/pwa/e2e/calendar.spec.ts` and `apps/pwa/e2e/lists.spec.ts`: the route-specific populated / empty / error state assertions (UI-SPEC Rules 4/5) on both device profiles, plus the TEST-02 precondition assertion that the harness reached the authenticated PWA via `DEV_AUTH_BYPASS` (no Authelia login, no OIDC mock) with no service-worker-sourced responses.
+
+Purpose: These specs prove the seeded data (Plan 02) renders correctly, that empty and error states degrade gracefully, and that the auth + SW-block preconditions (D-01/D-02) actually hold at runtime — the heart of TEST-01 (state coverage) and TEST-02 (authed reach).
+
+Output: `apps/pwa/e2e/calendar.spec.ts`, `apps/pwa/e2e/lists.spec.ts`.

+    Create `apps/pwa/e2e/calendar.spec.ts` importing `test, expect` from `@playwright/test`; runs on both profiles via the config matrix; relative `page.goto('/calendar')` only (Rule 8 — no absolute URL).
+    POPULATED state (Rule 5, after global-setup seed): goto `/calendar`; assert the Schedule-X calendar grid is visible (prefer a stable ARIA/role anchor; if none exists the codebase exposes `data-testid="schedule-x-calendar"` — use role/landmark first, testid only as the documented fallback for the widget wrapper since Schedule-X provides no semantic role); assert the EmptyState text `Nothing here` is NOT present (`await expect(page.getByText('Nothing here')).toHaveCount(0)`). Optionally assert the seeded event title `Seeded Test Event` is visible — but note Schedule-X renders the current week/month by default and the seed is ~tomorrow, so the chip is only guaranteed visible if tomorrow falls in the default view; if it may not, assert grid-present + empty-absent rather than chip-visible to keep the spec date-stable (DO NOT introduce date-dependent flakiness — this is exactly the Schedule-X drift the phase avoids).
+    ERROR state (Rule 5): register `await page.route('/api/events*', route => route.fulfill({ status: 500, body: JSON.stringify({ error: 'simulated' }) }))` BEFORE `page.goto('/calendar')` (route must be registered before navigation — Pattern 5); the events query retries twice (config), so allow time for the error branch; assert `getByRole('heading', { name: "Couldn't load events" })` is visible and `getByRole('button', { name: 'Retry' })` is visible; assert the Retry button boundingBox height ≥44 (Rule 1 within error state); assert no horizontal overflow (scrollWidth ≤ clientWidth) in the error state too. Call `await page.unroute('/api/events*')` (or use `{ times: ... }`) so the mock does not leak to later tests (Pattern 5 caution).
+    AUTH-BYPASS / SW precondition (TEST-02, Rule 7): add a test that, on goto `/calendar`, asserts the page did NOT land on the Authelia login (assert authed content is present — the BottomTabBar nav `getByRole('navigation', { name: 'Main navigation' })` and that the URL is not redirected to an external auth host) — proving DEV_AUTH_BYPASS reached the authed PWA without an OIDC mock. For SW-block evidence (D-02/Pitfall 15): the `serviceWorkers: 'block'` config option prevents registration; assert no service worker is registered via `await page.evaluate(() => navigator.serviceWorker?.controller)` returning null (no controlling SW), documenting in a comment that trace-level SW-source audit is the post-hoc check per UI-SPEC Rule 7. Header comment names TEST-01/TEST-02 + the run command (PATTERNS.md convention).

Assert no horizontal overflow on the populated list view.
+    EMPTY state (Rule 5): the harness needs an emptied lists view. DO NOT mutate the shared seeded DB mid-suite (that would race the populated test and break determinism — D-06).

(Confirm the exact lists endpoint path — `/api/lists` — by reading ListsIndex.tsx's query before finalizing the route glob.)

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| spec → dev PWA/API | Playwright drives the authed PWA via DEV_AUTH_BYPASS; read-only assertions + in-process page.route mocks; no real form writes |
+| harness → production | the auth posture asserted here (dev bypass) must never be the production posture |
+
+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Disposition | Mitigation Plan |
+|-----------|----------|-----------|-------------|-----------------|
+| T-07-09 | Elevation of Privilege | DEV_AUTH_BYPASS reaching production | mitigate | The spec asserts the authed PWA was reached via the bypass on the DEV stack only; the bypass is API-side and guarded by `NODE_ENV !== 'production'` (devBypass.ts). Production compose must not set it (documented in Plan 02 README). The spec does not enable the bypass; it depends on the dev stack having it. |
+| T-07-10 | Spoofing | OIDC/auth mocking masking a broken auth path | accept (designed out) | No OIDC mock is used (D-01) — auth comes from the real dev-bypass middleware; the auth-precondition test asserts genuine authed content, not a faked session. |
+| T-07-11 | Tampering | page.route mocks leaking between tests | mitigate | Every `page.route` (events 500, lists empty) is paired with `page.unroute` (or `{ times }`) so the mock does not bleed into the populated/auth tests; the shared seeded DB is never mutated by a spec (empty state is network-simulated, not a DB delete). |
