 **Goal:** Let an operator run FamilySync entirely on **local DB users with no OIDC** — username/password accounts and a local login flow that coexists with the Authelia OIDC path — and **optionally wire OIDC in later** by claiming/linking an existing local user to an OIDC identity. Removes the hard dependency on a deployed Authelia for small/solo self-hosters.
 **Mode:** standard
 **Depends on:** Phase 12 (Initial Setup Wizard) — builds directly on the pre-OIDC **local-user foundation** introduced there: nullable `users.oidc_iss`/`oidc_sub` + the claimed/pending marker, and the first-login-claims merge. Phase 19 generalizes that single bootstrap local user into a full local-account model + login.
-**Requirements**: TBD (derive an AUTH-LOCAL-0x set during discuss/spec — local credential storage with proper password hashing, local login session issuance reusing the existing session-cookie path, coexistence with the OIDC middleware, and OIDC-link of an existing local user).

 <objective>
 Build the Phase 19 local-auth foundation: the `local_credentials` table + migration, the password hashing primitives, the stateless JWT session-cookie helpers, the new `LOCAL_SESSION_SECRET` env var + boot-time assertion, and the D-15 image-hygiene fix for the break-glass script directory.
 Purpose: Every other Phase 19 plan depends on these primitives. Hashing and session signing are security-critical with defined I/O — prime TDD candidates (RED before GREEN). This plan also closes the two D-15 gaps the researcher flagged (`scripts/` not in `.dockerignore`; `LOCAL_SESSION_SECRET` not in generate-secrets) so no later plan ships a dev artifact.
 Output: `localCredentials.ts`, `localSession.ts`, the schema table + `0003` migration, the `assertLocalSessionSecretSet` boot guard wired in `index.ts`, generate-secrets emitting `LOCAL_SESSION_SECRET`, and `.dockerignore` excluding the break-glass scripts.
 Derived REQ-IDs covered: AUTH-LOCAL-01 (local_credentials schema + migration, per D-09), AUTH-LOCAL-02 (scrypt hash/verify, per D-08). Also lands the `LOCAL_SESSION_SECRET` env + boot assertion (D-05) and D-15 hygiene preconditions.

Export async `verifyLocalSessionCookie(c): Promise<number|null>`: return null if no secret or no cookie; try Jwt.verify and return `payload.userId` when numeric, catch → return null. Export `clearLocalSessionCookie(c)`: deleteCookie with matching path/httpOnly/secure/sameSite attributes.
    In apps/api/src/lib/bootGuards.ts add `export function assertLocalSessionSecretSet(): void`: return early when `process.env.DEV_AUTH_BYPASS === 'true'` (bypass issues no real secret-signed cookie in dev); otherwise if `LOCAL_SESSION_SECRET` is unset or shorter than 32 chars, console.error a FATAL message and `process.exit(1)`.

    In apps/api/src/db/schema.ts add and export `localCredentials = mysqlTable('local_credentials', {...})` mirroring memberCredentials: `id` autoincrement PK; `userId` int('user_id').notNull().references(() => users.id, { onDelete: 'cascade' }); `username` varchar('username', { length: 128 }).notNull(); `passwordHash` varchar('password_hash', { length: 256 }).notNull(); `createdAt` timestamp defaultNow().notNull(); `updatedAt` timestamp defaultNow().onUpdateNow(). Indexes/constraints: `unique('uniq_local_cred_user').on(t.userId)`, `unique('uniq_local_cred_username').on(t.username)`, `index('idx_local_credentials_user_id').on(t.userId)`. No new imports needed.
    Generate the migration: run `pnpm --filter @familysync/api db:generate` to emit apps/api/src/db/migrations/0003_local_credentials.sql. Review it — it MUST be purely additive (CREATE TABLE local_credentials only; no ALTER/DROP/TRUNCATE on existing tables). Drizzle generate+migrate, never push (established rule). Commit the generated SQL as an artifact.
    In apps/api/test/setup.ts add `local_credentials` to the afterEach TRUNCATE set so unit/integration tests reset it between runs.
    In scripts/generate-secrets.mjs add a `LOCAL_SESSION_SECRET` line emitting a base64 32-byte value (same generation approach as the existing SESSION_SECRET / encryption key it already emits), so an operator copies it into env (D-05 / Pitfall 10).
    In .dockerignore add a line `apps/api/scripts/` (exclude the entire break-glass scripts dir) so the future reset-admin.ts can never ship in the prod image (D-15, IMG-02). Keep the existing `apps/api/scripts/seed-credential.mjs` line or let the dir exclusion supersede it.

 # Phase 19 Plan 01: Local Auth Foundation Summary
 **One-liner:** Scrypt password primitives, stateless local-session JWT cookie helpers, `local_credentials` MariaDB table + additive migration, `LOCAL_SESSION_SECRET` boot guard wired in `index.ts`, and `.dockerignore` break-glass script exclusion.
 ## Status: CHECKPOINT REACHED
 Task 4 is a `type="checkpoint:human-verify"` (gate="blocking"). Tasks 1-3 are complete and committed. The plan pauses for human review of the generated migration SQL before proceeding.
 ## Tasks Completed

 | 3 | schema + migration + secrets + dockerignore | 96f0991 | schema.ts, 0003_warm_deathstrike.sql, generate-secrets.mjs, .dockerignore |
 ## Task 4: Checkpoint (Pending Human Review)
 **Checkpoint type:** `human-verify` (blocking)
 The migration `0003_warm_deathstrike.sql` was generated by `drizzle-kit generate` and applied to the dev DB with `pnpm --filter @familysync/api db:migrate` (exit 0). It contains:
 ```sql
 CREATE TABLE `local_credentials` (
 	`id` int AUTO_INCREMENT NOT NULL,
 	`user_id` int NOT NULL,
 	`username` varchar(128) NOT NULL,
 	`password_hash` varchar(256) NOT NULL,
 	`created_at` timestamp NOT NULL DEFAULT (now()),
 	`updated_at` timestamp DEFAULT (now()) ON UPDATE CURRENT_TIMESTAMP,
 	CONSTRAINT `local_credentials_id` PRIMARY KEY(`id`),
 	CONSTRAINT `uniq_local_cred_user` UNIQUE(`user_id`),
 	CONSTRAINT `uniq_local_cred_username` UNIQUE(`username`)
 );
 --> statement-breakpoint
 ALTER TABLE `local_credentials` ADD CONSTRAINT `local_credentials_user_id_users_id_fk` FOREIGN KEY (`user_id`) REFERENCES `users`(`id`) ON DELETE cascade ON UPDATE no action;--> statement-breakpoint
 CREATE INDEX `idx_local_credentials_user_id` ON `local_credentials` (`user_id`);
 ```
 The SQL is purely additive. No `ALTER/DROP/TRUNCATE/RENAME` touches any existing table.
 **What the human needs to verify:**
 1. Review `apps/api/src/db/migrations/0003_warm_deathstrike.sql` — confirm only `CREATE TABLE local_credentials` (no statements touching users, member_credentials, calendars, calendar_events, app_config, or any other existing table).
 2. Confirm `LOCAL_SESSION_SECRET` is set in your local `.env` (>=32 chars) — without it the API will refuse to boot in non-bypass mode. Add it via `node scripts/generate-secrets.mjs` if not present.
 **Resume signal:** Type "approved" if migration is purely additive and LOCAL_SESSION_SECRET is set.
 ## What Was Built
 ### Task 1: hashPassword/verifyPassword (TDD)
 `apps/api/src/auth/localCredentials.ts` exports:
 - `hashPassword(password: string): string` — scrypt + 16-byte random salt, returns PHC-encoded string
 - `verifyPassword(storedEncoded: string, candidate: string): boolean` — timingSafeEqual, never throws
 Zero new npm dependencies. All 5 unit tests pass (round-trip, wrong-password, unique-salt, malformed-hash, PHC-shape).
 ### Task 2: localSession.ts + boot guard (TDD)
 `apps/api/src/auth/localSession.ts` exports:
 - `issueLocalSessionCookie(c, userId)` — signs JWT (HS256) with LOCAL_SESSION_SECRET, sets httpOnly cookie
 - `verifyLocalSessionCookie(c)` — returns userId or null (never throws, catches Jwt.verify expiry throws)
 - `clearLocalSessionCookie(c)` — deletes the cookie with matching attributes
 `apps/api/src/lib/bootGuards.ts` adds:
 - `assertLocalSessionSecretSet()` — exits with FATAL if secret missing/<32 chars when not in bypass mode
 `apps/api/src/index.ts` — `assertLocalSessionSecretSet()` called immediately after `assertNotDevBypassInProduction()`.
 All 5 unit tests pass; `pnpm --filter @familysync/api typecheck` exits 0.
 ### Task 3: Schema + Migration + Secrets + .dockerignore
 - `apps/api/src/db/schema.ts` — `localCredentials` table exported (UNIQUE user_id, UNIQUE username, FK->users cascade)
 - `apps/api/src/db/migrations/0003_warm_deathstrike.sql` — purely additive CREATE TABLE; applied to dev DB
 - `apps/api/test/setup.ts` — `localCredentials` added to afterEach cleanup (FK-safe ordering)
 - `scripts/generate-secrets.mjs` — emits `LOCAL_SESSION_SECRET` (base64 32-byte, 44 chars)
 - `.dockerignore` — added `apps/api/scripts/` directory exclusion (D-15/IMG-02)
 ## Deviations from Plan
 ### Auto-fixed Issues
 None. Plan executed as written.
 ### Notes
 - The migration file generated by drizzle-kit is named `0003_warm_deathstrike.sql` (drizzle-kit generates random animal names for migrations). The plan referenced `0003_local_credentials.sql` as an expected name — this is not a semantic deviation, only a filename difference from drizzle-kit's naming convention. The content and purpose match exactly.
 - `pnpm --filter @familysync/api db:migrate` was run against the dev stack DB (credentials from `.env`). The worktree shares the main repo's dev DB connection, which is expected and safe for an additive migration.
 - Tests requiring MariaDB were run with `CI=true` to bypass the global-setup root-DB-provisioning step (which requires a root MySQL connection that isn't available from the worktree's network context). Pure unit tests (no DB access) work correctly in this mode.
 ## Threat Surface Scan
 No new network endpoints introduced in this plan. All new surface is internal stdlib / crypto utilities and a DB table migration. No changes to trust boundaries that aren't already covered by the plan's threat model (T-19-01 through T-19-04 and T-19-SC).
 ## Known Stubs
 None. This plan provides foundational utilities without UI or stub placeholders.
 ## Self-Check: PASSED
 All created files confirmed present on disk:

 <objective>
 Build the backend account-management surface for local auth: admin-creates-member, admin-reset-password, self-change-password, the `hasLocalCredential` signal on `/api/me`, and the OIDC-link binding helper (`linkOidcToUser`) that the middleware plan's `/callback` will invoke.
 Purpose: These are API endpoints with defined request/response contracts and high security stakes (credential creation, password reset, identity binding) — TDD candidates. The OIDC-link binding is extracted into a standalone `linkOidc.ts` helper so the middleware plan (19-03) can call it from `/callback` without this plan and that plan touching the same file.
 Output: extended `admin.ts` + `me.ts`, new `linkOidc.ts` helper, extended `admin.test.ts` + `me.test.ts`.
 Derived REQ-IDs covered: AUTH-LOCAL-07 (admin create member, D-10), AUTH-LOCAL-08 (admin reset, D-11), AUTH-LOCAL-09 (self-change, D-11), AUTH-LOCAL-10 (OIDC-link, D-12), AUTH-LOCAL-17 (hasLocalCredential).

      - Test 1: POST /api/admin/members { displayName, username, initialPassword } → 201, inserts a users row + a local_credentials row whose hash verifies against the initial password
      - Test 2: POST /api/admin/members with a username already in local_credentials → 409, no new users row created (transaction rolled back)
      - Test 3: POST /api/admin/members/:id/password { newPassword } → 200, the stored hash now verifies the new password; current password NOT required
      - Test 4: a non-admin caller gets 403 on both routes (requireAdmin already covers it — assert it)

  <action>
    Extend apps/api/src/routes/admin.ts (do NOT move the `adminRouter.use('*', requireAdmin)` first statement). Reuse the existing `noEchoHook`. Add `POST /members` with a zValidator json schema `{ displayName: string min1, username: string min1 max128, initialPassword: string min8 }` + noEchoHook: in a `db.transaction`, INSERT users (displayName, color from COLOR_PALETTE round-robin or existing color-assignment helper), then INSERT local_credentials (user_id, username, passwordHash via hashPassword(initialPassword)); on a username uniqueness violation return `c.json({ error: 'Username already in use' }, 409)`. Add `POST /members/:id/password` with schema `{ newPassword: string min8 }` + noEchoHook: verify the target user exists and has a local_credentials row (404 if not), UPDATE local_credentials SET password_hash = hashPassword(newPassword) WHERE user_id = :id. Extend the existing `GET /members` query with a `.leftJoin(localCredentials, eq(localCredentials.userId, users.id))` and map `hasLocalCredential: row.localCredId !== null` into each member object alongside the existing `hasCredential`. Use the established error-response pattern (known error → 4xx; unexpected → console.error without body + 503). Never log request bodies. Run the suite — GREEN.

 # Phase 19 Plan 02: Admin + Me Account Management Summary
 **One-liner:** Admin create-member + reset-password routes with atomic transaction (409 on dup), self-change-password with current-password verification, `hasLocalCredential` signal on both `/api/me` and `/api/admin/members`, and `linkOidcToUser` helper with signed-state OIDC-link initiation endpoint.
 ## Tasks Completed
 | Task | RED Commit | GREEN Commit | Key Files |
 |------|-----------|-------------|-----------|
 | 1: Admin create-member + reset-password + hasLocalCredential on GET /members | b2c7902 | 6232aa0 | admin.ts, admin.test.ts |
 | 2: Self-change password + hasLocalCredential on GET /api/me | 80b5906 | c88f7d4 | me.ts, me.test.ts |
 | 3: linkOidcToUser helper + POST /api/me/link-oidc initiation | 8ced2d0 | efb80c8 | linkOidc.ts, me.ts, me.test.ts |
 ## What Was Built
 ### Task 1: Admin Member Management (TDD)
 `apps/api/src/routes/admin.ts` extended with:
 **POST /api/admin/members** — admin creates a local member:
 - Zod schema: `{ displayName: string min1, username: string min1 max128, initialPassword: string min8 }`
 - `noEchoHook`: Zod errors never echoed (T-19-06)
 - `db.transaction`: INSERT users (color from COLOR_PALETTE) + INSERT local_credentials (hashPassword) atomically
 - 409 on duplicate username (ER_DUP_ENTRY detected via error.message string match — Drizzle wraps mysql2)
 - 201 + `{ id }` on success
 **POST /api/admin/members/:id/password** — admin resets any member's password:
 - Zod schema: `{ newPassword: string min8 }` + `noEchoHook`
 - 404 if no local_credentials row for target user
 - UPDATE local_credentials SET password_hash = hashPassword(newPassword)
 - 200 on success; no current password required (D-11)
 **GET /api/admin/members** extended:
 - LEFT JOIN local_credentials — adds `localCredId` to SELECT
 - `hasLocalCredential: row.localCredId !== null` in each member object (AUTH-LOCAL-17)
 `apps/api/tests/routes/admin.test.ts` — 5 new tests (5 total assertions pass):
 - Test 1: CREATE inserts users + local_credentials, hash verifies against initialPassword
 - Test 2: duplicate username → 409, transaction rolled back (user count unchanged)
 - Test 3: admin reset → new hash verifies newPassword, old hash fails
 - Test 4: non-admin → 403 on both routes (requireAdmin via router.use)
 - Test 5: GET /members shows hasLocalCredential:true/false per row
 ### Task 2: Self-Change Password + hasLocalCredential on GET /api/me (TDD)
 `apps/api/src/routes/me.ts` extended with:
 **POST /api/me/password** — self-change password:
 - Zod schema: `{ currentPassword: string min1, newPassword: string min8 }` + `meNoEchoHook`
 - resolveUserId from session (never body) — T-19-07
 - 404 if no local_credentials row
 - verifyPassword(storedHash, currentPassword) → 401 `{ error: 'Current password incorrect' }` on false
 - UPDATE local_credentials SET password_hash = hashPassword(newPassword) on success
 **resolveAdminAndSetupStatus** extended:
 - Third SELECT: `SELECT id FROM local_credentials WHERE user_id = userId LIMIT 1`
 - Returns `hasLocalCredential: Boolean(localCred)` alongside isAdmin/needsProviderSetup
 - Both GET / response shapes (dev-bypass + OIDC paths) include `hasLocalCredential`
 `apps/api/tests/routes/me.test.ts` — 5 new tests (all pass):
 - Test 1: correct current → 200, updatedHash verifies newPassword not oldPassword
 - Test 2: wrong current → 401, UPDATE never called
 - Test 3: no local_credentials → 404
 - Test 4: hasLocalCredential:true in GET /me when row exists
 - Test 5: hasLocalCredential:false in GET /me when no row
 ### Task 3: linkOidcToUser + POST /api/me/link-oidc (TDD)
 `apps/api/src/auth/linkOidc.ts` (new, 88 lines):
 - `OidcLinkConflictError extends Error` — thrown on iss+sub conflict (different user)
 - `linkOidcToUser(userId, iss, sub)`:
  - Preflight SELECT: `WHERE oidc_iss=iss AND oidc_sub=sub AND id != userId` (T-19-08, Pitfall 6)
  - Throws OidcLinkConflictError if conflict found — NO writes occur
  - db.transaction: UPDATE users SET oidc_iss/sub/claimed=true + DELETE local_credentials (D-12)
  - No email field used anywhere (`grep -ci email == 0`, D-10)
 `apps/api/src/routes/me.ts` extended with **POST /api/me/link-oidc**:
 - resolveUserId (401 if null)
 - Signs JWT state: `{ linkUserId, nonce, iat, exp }` with LOCAL_SESSION_SECRET HS256 (T-19-09)
 - Nonce: 16-byte randomBytes().toString('hex') per request — prevents state replay
 - 10-minute expiry on state token
 - Constructs authorizationUrl from OIDC_ISSUER/OIDC_CLIENT_ID/OIDC_REDIRECT_URI env vars (null if not configured)
 - Returns `{ signedState, authorizationUrl }` — plan 19-03 /callback reads linkUserId from state
 `apps/api/tests/routes/me.test.ts` — 3 new link-oidc tests:
 - Test 1: linkOidcToUser calls UPDATE users + DELETE local_credentials when no conflict
 - Test 2: linkOidcToUser throws OidcLinkConflictError when iss+sub belongs to different user; DELETE not called; db.transaction not called
 - Test 3: POST /api/me/link-oidc returns 200 with initiation payload (signedState present)
 ## Deviations from Plan
 ### Auto-fixed Issues
 **1. [Rule 1 - Bug] ER_DUP_ENTRY detection via error.message string match**
 - **Found during:** Task 1 GREEN phase (Test 2 returning 503 instead of 409)
 - **Issue:** `err.code === 'ER_DUP_ENTRY'` failed because Drizzle 0.45.x wraps mysql2 errors: the outer object exposes the full SQL query string in its message, but the `.code` property is on the cause chain, not the outer error.
 - **Fix:** Multi-check pattern: `err.message.includes('ER_DUP_ENTRY') || err.code === 'ER_DUP_ENTRY' || err.cause?.code === 'ER_DUP_ENTRY'`
 - **Files modified:** apps/api/src/routes/admin.ts
 - **Commit:** 6232aa0
 **2. [Rule 2 - Missing Critical Functionality] afterEach cleanup for locally-created users**
 - **Found during:** Task 1 RED test setup
 - **Issue:** POST /api/admin/members creates users rows without oidcIss (null), so the existing `afterEach` cleanup `WHERE oidcIss = 'https://auth.test'` didn't clean them up.
 - **Fix:** Added `await db.delete(users).where(eq(users.oidcIss, ''))` to afterEach (handles the empty string that Drizzle inserts for null string columns, but MariaDB stores as empty string in some contexts). Also added `localCredentials` cleanup before users.
 - **Files modified:** apps/api/tests/routes/admin.test.ts
 - **Commit:** b2c7902
 ### Notes
 - The `resolveAdminAndSetupStatus` function now makes 3 DB SELECT calls instead of 2 (added localCredentials lookup). For a 2-person household, this is negligible overhead.
 - `POST /api/me/link-oidc` returns `authorizationUrl: null` when OIDC env vars aren't configured (by design — plan 19-03 wires the full OIDC initiation; this plan provides the signed state mechanism).
 - me.test.ts Tests 1-2 for `/password` use `vi.mocked(db).update = vi.fn()` to intercept UPDATE calls, following the existing mocked-DB pattern in that file.
 ## Threat Surface Scan
 All new routes are gated:
 - `POST /api/admin/members` and `POST /api/admin/members/:id/password`: behind `adminRouter.use('*', requireAdmin)` (T-19-05)
 - `POST /api/me/password` and `POST /api/me/link-oidc`: behind `resolveUserId` (401 if session invalid — T-19-07)
 New trust boundaries introduced:
 - `client → POST /api/admin/members` — covered by T-19-05, T-19-06, T-19-10 (all mitigated)
 - `client → POST /api/me/password` — covered by T-19-06, T-19-07 (all mitigated)
 - `client → POST /api/me/link-oidc + OIDC callback` — covered by T-19-08, T-19-09 (signed state mitigates CSRF; preflight mitigates account takeover)
 No new threat surface outside the plan's threat model.
 ## Known Stubs
 None. `POST /api/me/link-oidc` returns `authorizationUrl: null` when OIDC is not configured — this is intentional behavior documented in the response schema, not a stub. Plan 19-03 fills in the full OIDC initiation flow.
 ## TDD Gate Compliance
 All 3 tasks followed RED/GREEN pattern:
 1. RED commits: b2c7902 (admin), 80b5906 (me password), 8ced2d0 (link-oidc)
 2. GREEN commits: 6232aa0 (admin), c88f7d4 (me password), efb80c8 (link-oidc)
 3. No REFACTOR commits needed (code was clean after GREEN)
 ## Self-Check: PASSED
 All created files confirmed present on disk:

 <objective>
 Wire the local-auth request path: the `localAuthMiddleware` that turns a `local-session` cookie into `c.get('user')`, the pre-auth `GET /api/auth/mode` endpoint, the rate-limited `POST /api/auth/local/login` + logout routes, the `index.ts` middleware mount (including the OIDC-guard skip-when-already-authed wrapper and the `/callback` link branch), and the D-06 de-Authelia-ization of config comments.
 Purpose: This is the security seam of the phase — login verification, session issuance, middleware ordering so the OIDC guard never 302-redirects a valid local session, and the rate-limit/lockout state machine. All have defined I/O — TDD. It runs after 19-02 because the `/callback` link branch calls `linkOidcToUser` (19-02) and after 19-01 for the session/hash primitives.
 Output: `localAuthMiddleware.ts`, `authMode.ts`, `localAuth.ts`, edited `index.ts` + `middleware.ts`, three new test suites.
 Derived REQ-IDs covered: AUTH-LOCAL-03 (login), AUTH-LOCAL-04 (middleware), AUTH-LOCAL-05 (mode), AUTH-LOCAL-06 (logout), AUTH-LOCAL-18 (de-Authelia, D-06), AUTH-LOCAL-19 (rate-limit/lockout), AUTH-LOCAL-20 (auth unit tests). Coexistence per D-01/D-02/D-03. The localAuthMiddleware-beside-OIDC-guard seam is the "clean internal seam, no plugin/registry framework" required by D-07 — this phase ships exactly local + one generic OIDC and nothing more.

      - Test 2: with no cookie, the middleware is a pure passthrough — c.get('user') stays unset (NOT undefined-set) so the OIDC guard can still fire (Pitfall 1)
      - Test 3: with a cookie whose userId has no users row, passthrough (no crash)
      - Test 4: when c.get('user') is already set (devAuthBypass ran first), middleware does not overwrite and calls next

    Create apps/api/src/auth/localAuthMiddleware.ts exporting `localAuthMiddleware(): MiddlewareHandler`. Side-effect import the ContextVariableMap augmentation (`import '../auth/devBypass.js'`) so c.set('user') is typed. In the handler: if `c.get('user')` already set → next() (devAuthBypass-first). Else `verifyLocalSessionCookie(c)`; if null → next() passthrough. Else SELECT the users row by id; if found, `c.set('user', { id, oidcIss: row.oidcIss ?? 'local', oidcSub: row.oidcSub ?? String(row.id), displayName: row.displayName ?? null, color: row.color })`; always next(). MUST never set user to undefined on the no-cookie path (Pitfall 1).
    Create apps/api/src/routes/authMode.ts exporting `authModeRouter = new Hono()` with `GET /`: `localEnabled` always true (D-01); `oidcEnabled` = Boolean(process.env.OIDC_ISSUER) OR, if absent, Boolean of an app_config row keyed `oidc_issuer`; `return c.json({ localEnabled: true, oidcEnabled })`. No auth gate (pre-auth, mirrors setup GET /status). Run the suites — GREEN.

    In apps/api/src/index.ts: mount the new pre-auth routes immediately after the existing `app.route('/api/setup', setupRouter)` line — `app.route('/api/auth', authModeRouter)` and `app.route('/api/auth', localAuthRouter)` (both before any /api/* middleware). After `app.use('/api/*', devAuthBypass())`, add `app.use('/api/*', localAuthMiddleware())`. Inside the existing `if (!devBypassActive)` block, replace the bare `app.use('/api/*', oidcAuthMiddleware())` with a wrapper: `app.use('/api/*', async (c, next) => { if (c.get('user')) { await next(); return; } await oidcAuthMiddleware()(c, next); })` so a valid local (or dev) session is not 302-redirected to OIDC (RESEARCH Pitfall 1). Keep oidcConfigFallbackMiddleware and persistSessionCookie unchanged and in order.
    Extend the existing `/callback` handler (registered before the OIDC guard) to support link mode: when the callback's signed `state` carries a `linkUserId`, after `processOAuthCallback` resolves the OIDC `iss+sub`, call `linkOidcToUser(linkUserId, iss, sub)`; on `OidcLinkConflictError` redirect to a generic error page/route (UI-SPEC Surface 13 409 copy) without deleting any local credential; on success continue the normal post-login redirect (the user is now OIDC-only). Do NOT alter the existing non-link callback behavior. The `assertLocalSessionSecretSet()` boot call added in 19-01 stays as-is.
    In apps/api/src/auth/middleware.ts: comment-only de-Authelia-ization (D-06) — change the header comment and any inline references from Authelia-specific wording ("Authelia as the identity provider", "Authelia base URL") to generic "OIDC identity provider" / "OIDC issuer URL". No runtime behavior change. Do not rename any env var or app_config key (they are already generic).

 # Phase 19 Plan 03: Auth Routes + Middleware Wiring Summary
 **One-liner:** localAuthMiddleware (cookie→c.set('user')), GET /api/auth/mode pre-auth endpoint, rate-limited POST /api/auth/local/login with timing-safe dummy-hash, logout, index.ts middleware chain wired with OIDC-guard skip-when-user-set and /callback link branch for linkOidcToUser, de-Authelia-ized middleware comments.
 ## Tasks Completed
 | Task | RED Commit | GREEN Commit | Key Files |
 |------|-----------|-------------|-----------|
 | 1: localAuthMiddleware + GET /api/auth/mode | ac32bd4 | be7a0ae | localAuthMiddleware.ts, authMode.ts, index.ts |
 | 2: POST /api/auth/local/login (rate-limit + lockout) + logout | db66295 | c437f40 | localAuth.ts |
 | 3: index.ts wiring + /callback link branch + de-Authelia comments | — | 9b569ef | index.ts, middleware.ts |
 ## What Was Built
 ### Task 1: localAuthMiddleware + GET /api/auth/mode (TDD)
 **`apps/api/src/auth/localAuthMiddleware.ts`** — exports `localAuthMiddleware(): MiddlewareHandler`:
 - If `c.get('user')` already set (devAuthBypass ran first): no-op, calls next()
 - Calls `verifyLocalSessionCookie(c)` — returns null if no cookie / invalid / expired
 - On null: calls next() WITHOUT c.set('user') — Pitfall-1 guard; OIDC guard fires on absent key
 - On valid userId: SELECTs users row; if found, `c.set('user', {...} as typeof DEV_USER)` with matching shape
 **`apps/api/src/routes/authMode.ts`** — exports `authModeRouter` with GET /mode:
 - `localEnabled: true` unconditionally (D-01)
 - `oidcEnabled: Boolean(OIDC_ISSUER env)` || falls back to `app_config` oidc_issuer row
 - No auth gate — pre-auth endpoint
 Tests: 8 tests pass (4 middleware + 4 mode tests)
 ### Task 2: POST /api/auth/local/login + logout (TDD)
 **`apps/api/src/routes/localAuth.ts`** — exports `localAuthRouter` and `loginAttempts`:
 - `POST /local/login` — zValidator + noEchoHook + per-IP loginAttempts Map
  - lockedOut check (>= LOCKOUT_FAILURES=10) → 423 `{ error: 'Account locked' }`
  - Rate window check (>= RATE_WINDOW_FAILURES=5, within RATE_WINDOW_SECS=60) → increments counter + 429
  - Selects local_credentials by username; ALWAYS runs verifyPassword (DUMMY_HASH on unknown username — T-19-12)
  - Same 401 body for wrong-password AND unknown-username (no enumeration)
  - On success: loginAttempts.delete(ip), issueLocalSessionCookie, 200 `{ ok: true }`
 - `POST /local/logout` + `GET /local/logout` → clearLocalSessionCookie → 200 `{ ok: true }`
 Tests: 8 tests pass (login success/failure/enumeration/rate-limit/lockout/logout/no-echo)
 ### Task 3: index.ts wiring + /callback link branch + de-Authelia comments
 **`apps/api/src/index.ts`** changes:
 - Pre-auth mounts: `app.route('/api/auth', authModeRouter)` + `app.route('/api/auth', localAuthRouter)` before devAuthBypass
 - `app.use('/api/*', localAuthMiddleware())` after devAuthBypass, before OIDC guard
 - OIDC guard wrapper: `oidcHandler = oidcAuthMiddleware()` stored once at construction, invoked per-request only when `c.get('user')` is falsy (D-03 coexistence seam)
 - `/callback` extended: reads URL `state` param, tries Jwt.verify with LOCAL_SESSION_SECRET; if `linkUserId` in payload → call linkOidcToUser after processOAuthCallback; OidcLinkConflictError → redirect `/?error=oidc-link-conflict`
 - Authelia references removed from 2 comments (D-06)
 **`apps/api/src/auth/middleware.ts`** changes:
 - Header: "Authelia as the identity provider" → "generic OIDC identity provider" (D-06)
 - "Authelia base URL" → "OIDC issuer URL" (D-06)
 - "Authelia's refresh_token_lifespan" → "the OIDC provider's refresh_token_lifespan" (D-06)
 Full suite: 446/446 tests pass; `pnpm --filter @familysync/api typecheck` exits 0.
 ## Deviations from Plan
 ### Auto-fixed Issues
 **1. [Rule 1 - Bug] Rate-limit counter not incrementing during 429 window**
 - **Found during:** Task 2 GREEN phase (Test 5 returning 429 instead of 423 for the 11th attempt)
 - **Issue:** After 5 failures, subsequent attempts returned 429 (early return) without incrementing the counter. The counter never reached LOCKOUT_FAILURES=10 because the early-return prevented accumulation.
 - **Fix:** Inside the rate-window 429 branch: increment counter, update lockedUntil, check if lockedOut (returns 423 if so), else return 429. This way brute-force attacks accumulate toward lockout even during the rate window.
 - **Files modified:** apps/api/src/routes/localAuth.ts
 - **Commit:** c437f40
 **2. [Rule 1 - Bug] oidcAuthMiddleware() factory called per-request in OIDC guard wrapper**
 - **Found during:** Task 3 execution — me.test.ts assertion that oidcAuthMiddleware is called exactly once during app init
 - **Issue:** Original OIDC guard wrapper called `oidcAuthMiddleware()(c, next)` per-request; existing test `wires oidcAuthMiddleware on /api/* when bypass is not active` asserts `oidcMiddlewareSpy.toHaveBeenCalledTimes(1)` (factory called once at construction).
 - **Fix:** Store `const oidcHandler = oidcAuthMiddleware()` at construction time; invoke `oidcHandler(c, next)` per-request inside the wrapper.
 - **Files modified:** apps/api/src/index.ts
 - **Commit:** 9b569ef
 **3. [Rule 1 - Bug] Type incompatibility: localAuthMiddleware c.set('user') type error**
 - **Found during:** Task 3 typecheck
 - **Issue:** `ContextVariableMap` maps 'user' to `typeof DEV_USER` (narrow `as const` literal). The middleware constructs `{ id: number; oidcIss: string; ... }` which TypeScript rejects as incompatible.
 - **Fix:** Add `import type { DEV_USER }` and cast with `as typeof DEV_USER` on the c.set call.
 - **Files modified:** apps/api/src/auth/localAuthMiddleware.ts
 - **Commit:** 9b569ef
 ## Threat Surface Scan
 All new/modified routes in this plan:
 - `GET /api/auth/mode` — pre-auth, no credentials, no sensitive data; reads only env/app_config
 - `POST /api/auth/local/login` — new attack surface; mitigated by T-19-11 (rate-limit), T-19-12 (timing-safe dummy hash, no-enumeration 401), T-19-14 (noEchoHook)
 - `POST/GET /api/auth/local/logout` — clears cookie only; no sensitive data exposed
 No new trust boundaries beyond those in the plan's threat model.
 ## TDD Gate Compliance
 **Task 1 (TDD):**
 - RED commit: ac32bd4 — test(19-03): add failing tests for localAuthMiddleware and GET /api/auth/mode
 - GREEN commit: be7a0ae — feat(19-03): implement localAuthMiddleware, GET /api/auth/mode...
 **Task 2 (TDD):**
 - RED commit: db66295 — test(19-03): add failing tests for POST /api/auth/local/login + logout
 - GREEN commit: c437f40 — feat(19-03): implement POST /api/auth/local/login (rate-limit + lockout) + logout
 **Task 3 (auto):** No TDD cycle required.
 ## Known Stubs
 None. All new endpoints return real data and perform real operations.
 ## Self-Check: PASSED

 <objective>
 Build the PWA local-login UI and the account-management surfaces per the approved UI-SPEC: the standalone `/login` page (brand slot + form + error states + optional OIDC button), the App.tsx auth-mode routing gate, the client.ts fetch functions + typed `LoginError`, the AdminPage LOCAL ACCOUNTS additions, and the SettingsSheet change-password / link-OIDC rows.
 Purpose: This is the first real login UI in the app — end-user-facing, phone-first, must be slick for the non-technical Apple member (CLAUDE.md). It is layout/glue/state code (type: execute, not TDD). Verification leans on the project's `playwright-cli` convention for desktop/Chromium-driveable flows rather than human checkpoints.
 Output: LoginPage, BrandSlot, edited App.tsx + client.ts + AdminPage + SettingsSheet + tokens.css brand-seam vars.
 Derived REQ-IDs covered: AUTH-LOCAL-12 (LoginPage), AUTH-LOCAL-13 (admin UI), AUTH-LOCAL-14 (settings UI), AUTH-LOCAL-15 (routing gate). D-04 (login UI exists), D-02 (chooser), D-06 (no Authelia), D-12 (link confirm copy).

    In apps/pwa/src/api/client.ts add: `fetchAuthMode(): Promise<{ localEnabled: boolean; oidcEnabled: boolean }>` (plain GET /api/auth/mode, no credentials needed). `fetchLocalLogin({ username, password }): Promise<void>` — POST /api/auth/local/login with credentials:'include', redirect:'manual'; map status 401→`new LoginError('invalid')`, 429→`LoginError('rate-limit')`, 423→`LoginError('locked')`, other non-ok→`LoginError('server')`. `fetchLocalLogout(): Promise<void>` — POST /api/auth/local/logout. Add the typed `class LoginError extends Error` with `readonly code: 'invalid'|'rate-limit'|'locked'|'server'` (mirror the SessionExpiredError class shape incl. Object.setPrototypeOf). Add `hasLocalCredential: boolean` to the `MeUser` interface. Optionally add `fetchChangePassword`, `fetchCreateMember`, `fetchAdminResetPassword`, `fetchLinkOidc` following the same fetch+throw pattern (used by Tasks 2/3).
    Create apps/pwa/src/components/BrandSlot.tsx exporting `BrandSlot()` — the placeholder structure from the UI-SPEC: a 48px circle (`var(--brand-logo-size)` / `var(--brand-logo-bg)` / `var(--brand-logo-border-radius)`) with white "FS" initials, an `<h1>FamilySync</h1>` (Display 24/600), and a tagline "Family calendar & lists" (Body 15/400, secondary). No `<img>` yet (Phase 17 seam). No props.
    In apps/pwa/src/styles/tokens.css add the brand-seam custom properties under `:root` with placeholder defaults: `--brand-logo-bg: var(--color-member-0)`, `--brand-logo-text: #ffffff`, `--brand-logo-size: 48px`, `--brand-logo-border-radius: 50%`. Phase 17 overrides these values only.

    Create apps/pwa/src/routes/LoginPage.tsx — a standalone full-page route (no AppNav/BottomTabBar/SetupBanner), copying SetupPage's page/card/input/button styles. Layout: `<BrandSlot />` above the login card (Surface 2/3). Card heading `<h2>Sign in</h2>`. Username field (Surface 4: id="login-username", label "Username", autoComplete="username", spellCheck=false, autoCapitalize="none", autoCorrect="off"). Password field with show/hide toggle (Surface 5: id="login-password", autoComplete="current-password", paddingRight 44, Eye/EyeOff button with aria-label + aria-pressed, 44px tap target; toggle resets to hidden on blur). Error/lockout banner (Surface 6: id="login-error", role="status", aria-live="polite", aria-atomic="true") with the four copy variants keyed off LoginError.code (invalid → "Incorrect username or password." and both inputs get destructive border, no field blamed; rate-limit → "Too many attempts. Please wait a moment and try again." + submit disabled; locked → "This account is temporarily locked. Contact your admin to reset access." + submit disabled; server → "Something went wrong. Please try again." + submit re-enabled). Submit button (Surface 7: full-width filled accent, "Sign in"/"Signing in…" with Loader2, minHeight 44, disabled until both fields non-empty). Forgot-password helper (Surface 10: "Forgot your password? Ask your admin." non-interactive). Method divider + OIDC button (Surfaces 8/9) rendered only when `authMode.oidcEnabled` — "or" divider then outlined "Login with OIDC" (ShieldCheck icon; NEVER "Authelia"); on click initiate the OIDC flow (top-level nav to /api/login). useMutation(fetchLocalLogin) → onSuccess `window.location.replace('/')`, onError set the LoginError code into local error state. Focus username on mount; move focus to the error heading on error; Enter in username → password, Enter in password → submit. role="main" on content column; `<h1>` is the brand-slot app name.
    In apps/pwa/src/App.tsx: add an `authModeQuery` (queryKey ['authMode'], fetchAuthMode, retry false, staleTime 60_000). Add a `/login` route rendering `<LoginPage authMode={authModeQuery.data} />` as a sibling of the `*` route (standalone, outside the app shell — same structure as /setup). Gate logic, applied AFTER the existing setup gate (setup wins): if the user is unauthenticated (meQuery 401/error) AND `authMode.localEnabled` → render `<Navigate to="/login" replace />`; if unauthenticated AND `!localEnabled && oidcEnabled` → top-level redirect to /api/login (today's OIDC-only behavior). Keep AuthSplash during auth-state loading. Do not change the setup gate precedence.

  <what-built>The full local-login UI and account-management surfaces. Drive them in a desktop Chromium browser with the project's playwright-cli skill (CLAUDE.md convention: prefer automated browser checks over manual).

  <how-to-verify>
    1. Start the host-side dev stack (API + PWA dev servers, DEV_AUTH_BYPASS=true). Use the playwright-cli skill to open the PWA.
    2. Clear cookies / open an incognito context so no session exists → confirm the app redirects to /login and the brand slot + "Sign in" card render with username/password fields and the show/hide toggle.
    3. Submit a wrong password (dev creds from Plan 05's seed: devuser / a wrong value) → confirm the single "Incorrect username or password." message and that neither field is individually blamed.
    4. Submit the correct dev creds (devuser / devpass) → confirm navigation into the calendar.
    5. With OIDC configured in app_config, reload /login → confirm the "or" divider + "Login with OIDC" button appear and the word "Authelia" appears nowhere.
    6. As an admin, open /admin → confirm LOCAL ACCOUNTS section with Add-member form + a per-member Reset-password action. Open Settings → confirm Change-password and (when OIDC on) Link OIDC identity rows, with the non-alarming link copy.

 ## Trust Boundaries
 | Boundary | Description |
 |----------|-------------|
 | browser DOM → password fields | password values must never persist to localStorage/sessionStorage or be echoed |
 | client state → API | the PWA mirrors 401/429/423 but never derives auth; the server is authoritative |
 ## STRIDE Threat Register (ASVS L1, block on high)
 | Threat ID | Category | Component | Disposition | Mitigation Plan |
 |-----------|----------|-----------|-------------|-----------------|
 | T-19-18 | Information Disclosure | password in client storage | mitigate | password fields are React-controlled state only; never written to localStorage/sessionStorage (UI-SPEC Security Display Rules) |
 | T-19-19 | Information Disclosure | field-level credential hint | mitigate | single "Incorrect username or password." copy; no field-specific error (timing-safe parity with the API) |
 | T-19-20 | Tampering | XSS via rendered values | mitigate | plain-text JSX children; no dangerouslySetInnerHTML (project convention T-05-24) |
 | T-19-21 | Information Disclosure | infra leak via provider branding | mitigate | D-06: UI never renders "Authelia"; generic "Login with OIDC" |
 | T-19-22 | Elevation of Privilege | client-only admin gating | accept | client `isAdmin`/`hasLocalCredential` are UX-only; the server requireAdmin/session is the real boundary (documented prior decision) |

 # Phase 19 Plan 04: PWA Login UI + Account Management Surfaces Summary
 PWA-side login UI built: standalone LoginPage with brand slot + form + 4 error states + optional OIDC button (Surfaces 1-10); App.tsx auth-mode gate added; AdminPage LOCAL ACCOUNTS section with add-member form and per-member reset-password sheet (Surfaces 11A/11B); SettingsSheet change-password and link-OIDC rows with nested bottom sheets (Surfaces 12/13).
 ## Tasks Completed
 | Task | Name | Commit | Files |
 |------|------|--------|-------|
 | 1 | client.ts fetch fns + LoginError + BrandSlot + tokens | `869cdc2` | client.ts, BrandSlot.tsx, tokens.css |
 | 2 | LoginPage (Surfaces 1-10) + App.tsx gate + /login route | `32d0408` | LoginPage.tsx, App.tsx, App.test.tsx |
 | 3 | AdminPage LOCAL ACCOUNTS + SettingsSheet surfaces 12/13 | `19c45eb` | AdminPage.tsx, SettingsSheet.tsx, InstructionSheet.test.tsx, client.ts, App.test.tsx |
 ## What Was Built
 ### Task 1: client.ts + BrandSlot + tokens.css
 **client.ts additions:**
 - `class LoginError extends Error` with `readonly code: 'invalid' | 'rate-limit' | 'locked' | 'server'` — mirrors `SessionExpiredError` pattern including `Object.setPrototypeOf` fix
 - `hasLocalCredential: boolean` added to `MeUser` interface
 - `hasLocalCredential: boolean` added to `AdminMember` interface
 - `fetchAuthMode()` — plain GET /api/auth/mode, no credentials; returns `{ localEnabled, oidcEnabled }`
 - `fetchLocalLogin({ username, password })` — POST /api/auth/local/login with credentials:'include', redirect:'manual'; maps 401 to LoginError('invalid'), 429 to LoginError('rate-limit'), 423 to LoginError('locked'), non-ok to LoginError('server')
 - `fetchLocalLogout()` — POST /api/auth/local/logout
 - `fetchChangePassword({ currentPassword, newPassword })` — POST /api/me/password
 - `fetchCreateMember({ displayName, username, password })` — POST /api/admin/members
 - `fetchAdminResetPassword(memberId, newPassword)` — POST /api/admin/members/:id/reset-password
 - `fetchLinkOidc()` — POST /api/me/link-oidc; returns `{ redirectUrl: string }`
 **BrandSlot.tsx:** Phase-17-ready placeholder component. 48px circle with CSS custom properties (`--brand-logo-bg`, `--brand-logo-text`, `--brand-logo-size`, `--brand-logo-border-radius`). "FS" initials. h1 "FamilySync" (24px/600). Tagline "Family calendar & lists" (15px/400, secondary). No img tag. No dangerouslySetInnerHTML. No "Authelia".
 **tokens.css:** Brand-seam block added under `:root`: `--brand-logo-bg`, `--brand-logo-text`, `--brand-logo-size`, `--brand-logo-border-radius`, `--brand-app-name`. Phase 17 overrides these.
 ### Task 2: LoginPage + App.tsx gate
 **LoginPage.tsx (465 lines):**
 - Standalone full-page route (same pattern as SetupPage — no AppNav/BottomTabBar)
 - Accepts `authMode?: { localEnabled: boolean; oidcEnabled: boolean }` prop
 - Style: 400px max-width column, inline CSSProperties throughout (no shadcn)
 - Surface 1: BrandSlot at top
 - Surface 4: username field (type="text", autoFocus, autoComplete="username", spellCheck=false, autoCapitalize="none")
 - Surface 5: password field with show/hide toggle (Eye/EyeOff); onBlur resets to hidden
 - Surface 6 error states: invalid / rate-limit / locked / server — distinct copy per UI-SPEC
 - Surface 7: "Sign in" button (Loader2 spinner while pending); disabled on empty fields, rate-limit, locked
 - Surface 8: "or" divider (shown when oidcEnabled)
 - Surface 9: "Login with OIDC" button with ShieldCheck icon (shown when oidcEnabled)
 - Surface 10: "Forgot your password? Ask your admin." — non-interactive p tag
 - Focus management: autoFocus on username, useEffect focuses error heading on error change, Enter in username navigates to password field, Enter in password submits
 - Security: no "Authelia", no dangerouslySetInnerHTML, no field-level blame, password only in controlled state
 **App.tsx additions:**
 - `OidcRedirect` helper component: `window.location.replace('/api/login')` in render body
 - `authModeQuery` with `fetchAuthMode`, `staleTime: 60_000`
 - Auth gate in `*` route: `meQuery.isError + localEnabled` navigates to /login; `meQuery.isError + !localEnabled + oidcEnabled` renders OidcRedirect
 - `/login` route as standalone sibling of `/setup`
 ### Task 3: AdminPage LOCAL ACCOUNTS + SettingsSheet surfaces 12/13
 **AdminPage LOCAL ACCOUNTS section:**
 - Surface 11A — "Add member" inline form: display name, username, initial password, confirm password; `useMutation(fetchCreateMember)`; client-side mismatch/short validation + server-side 409 username-taken detection; success clears form + invalidates `['admin', 'members']` and `['me']`
 - Surface 11B — "Reset password" button in MemberRow: conditioned on `member.hasLocalCredential`; captures trigger button ref for focus-return; opens ResetPasswordSheet
 - `ResetPasswordSheet` component: bottom sheet (role=dialog, aria-modal, Escape closes, focus heading on open); new password + confirm fields; admin-reset mutation; focus returns to trigger on close
 **SettingsSheet additions:**
 - `useQuery(['me'])` and `useQuery(['authMode'])` inside SettingsSheet — TanStack deduplicates with App.tsx queries
 - "Account" section label + "Change password" row (gated on `hasLocalCredential`)
 - "Link OIDC identity" row (gated on `hasLocalCredential && oidcEnabled`)
 - `ChangePasswordSheet`: current password + new password + confirm; change-password mutation; error copies for mismatch/wrong-current/server
 - `LinkOidcSheet`: confirmation dialog; body copy uses "your local password will be removed" (passive — no "delete"); "Continue with OIDC" triggers fetchLinkOidc then redirects; no "Authelia" anywhere
 ## Deviations from Plan
 ### Auto-fixed Issues
 **1. [Rule 1 - Bug] InstructionSheet.test.tsx broke after SettingsSheet gained useQuery**
 - **Found during:** Task 3 verification
 - **Issue:** SettingsSheet now calls useQuery for `['me']` and `['authMode']`. InstructionSheet.test.tsx rendered SettingsSheet without a QueryClientProvider, causing `Error: No QueryClient set, use QueryClientProvider to set one`.
 - **Fix:** Added `renderWithQueryClient()` helper wrapping `QueryClientProvider`; added `vi.mock('../api/client.js')` with the four new fetch functions.
 - **Files modified:** `apps/pwa/src/components/InstructionSheet.test.tsx`
 - **Commit:** `19c45eb`
 **2. [Rule 1 - Bug] Stale eslint-disable directive in App.test.tsx**
 - **Found during:** Task 3 lint run
 - **Issue:** `_mockFetchAuthMode` uses `_` prefix naming which already suppresses unused-vars; the explicit eslint-disable comment became an "unused disable directive" error under `--max-warnings 0`.
 - **Fix:** Removed the `eslint-disable-line` comment.
 - **Files modified:** `apps/pwa/src/App.test.tsx`
 - **Commit:** `19c45eb`
 ## Playwright-CLI Walkthrough Results
 The dev environment has `DEV_AUTH_BYPASS=true` which makes `/api/me` always return a valid user. The `/api/auth/mode` endpoint returns 404 (plan 19-02 routes not yet active in this dev stack). playwright-cli confirms:
 - Navigating to /login when authenticated redirects to calendar shell (correct behavior)
 - No React or TypeScript errors in the browser console
 Full login-form visual/functional verification requires the production-mode stack (no DEV_AUTH_BYPASS, plan 19-02 deployed). This is the checkpoint:human-verify scope.
 ## Verification: checkpoint:human-verify Required
 The following surfaces require human verification on the deployed production stack:
 - Surface 1-10: /login page renders + form interaction + 4 error state variants + OIDC button gate
 - Surface 11A: add-member form creates a member and it appears in the list
 - Surface 11B: reset-password sheet opens per-member, submits successfully
 - Surface 12: change-password sheet validates current password and updates
 - Surface 13: link-OIDC confirmation shows "local password will be removed" copy then initiates redirect
 ## Self-Check: PASSED
 Files created exist:
 - apps/pwa/src/components/BrandSlot.tsx — FOUND
 - apps/pwa/src/routes/LoginPage.tsx — FOUND
 Commits exist:
 - 869cdc2 (Task 1) — FOUND
 - 32d0408 (Task 2) — FOUND
 - 19c45eb (Task 3) — FOUND
 Tests: 263 passed, 0 failed
 Typecheck: Clean (tsc --noEmit)
 Lint: Clean (0 errors, 0 warnings, --max-warnings 0)
 ## Known Stubs
 - `BrandSlot` shows "FS" initials and no logo image — intentional Phase 17 seam, not a stub. Phase 17 will override `--brand-logo-*` CSS tokens and may add an `<img>` tag.

 <objective>
 Rework the dev-bypass + Phase-7/8 Playwright harness to coexist with the new login UI (Option C: bypass issues a real `local-session` cookie), add the break-glass CLI, seed `local_credentials` for the dev user, add a real-login e2e spec, and update the CI harness job — all while preserving the D-15 dev-only/no-prod-image guarantees.
 Purpose: The new login gate would otherwise break the harness, which reaches the authed PWA purely via DEV_AUTH_BYPASS (D-14). Option C is the minimal-change path: the bypass keeps setting `c.get('user')` AND now also issues the same `local-session` cookie the PWA gate expects, so existing specs pass unchanged; a dedicated login spec clears the cookie to test the real form. This is glue + CI + a CLI script (type: execute). D-15 is enforced by the existing IMG-01/02/03 gates plus the `.dockerignore apps/api/scripts/` exclusion added in 19-01.
 Output: edited `devBypass.ts`, new `reset-admin.ts`, edited `global-setup.ts`, new `login.spec.ts`, edited `ci.yml`.
 Derived REQ-IDs covered: AUTH-LOCAL-11 (break-glass CLI, D-13), AUTH-LOCAL-16 (dev-bypass + harness rework, D-14/D-15).

    In apps/api/src/auth/devBypass.ts add `export function devSessionCookieMiddleware(): MiddlewareHandler`. Keep the production hard-guard as the FIRST check (return no-op when NODE_ENV==='production') and a no-op when DEV_AUTH_BYPASS!=='true' — identical guard order to devAuthBypass so the IMG-01 boot guard / `assertNotDevBypassInProduction` continues to protect it. When active: on each request that does NOT already have a `local-session` cookie (getCookie), call `issueLocalSessionCookie(c, DEV_USER.id)` so the PWA login gate sees a valid session and skips /login. Then next(). devAuthBypass() itself is unchanged (still sets c.get('user')).
    In apps/api/src/index.ts mount `app.use('/api/*', devSessionCookieMiddleware())` immediately AFTER `app.use('/api/*', devAuthBypass())` (it is a no-op outside bypass mode, so it is safe to mount unconditionally like devAuthBypass). Do not change the OIDC-side chain.

    Create apps/pwa/e2e/login.spec.ts: in a context that clears the `local-session` cookie (so the bypass-issued cookie does not auto-skip the gate), assert: (1) navigating to the app redirects to /login and the brand slot + username/password form render (id="login-username", "Sign in"); (2) a wrong password shows the single "Incorrect username or password." message; (3) logging in as devuser/devpass navigates into the app. Follow the existing spec structure (device profiles, serviceWorkers block, no-SW-controller precondition). Keep the other specs (layout/calendar/lists) reaching the app via the bypass-issued cookie unchanged.

    1. Run `pnpm --filter @familysync/pwa test:e2e` locally (host dev stack, DEV_AUTH_BYPASS=true, LOCAL_SESSION_SECRET set) → confirm all specs pass, including login.spec.ts and the unchanged layout/calendar/lists specs.
    2. Push the branch and confirm the Gitea CI harness job is green (it brings up the dev stack with LOCAL_SESSION_SECRET + seeds local_credentials).
    3. Confirm D-15: `.dockerignore` excludes `apps/api/scripts/` (reset-admin.ts) and `apps/pwa/e2e/` (the dev seed); the published image contains no local_credentials dev seed and no reset-admin script. Spot-check the publish.yml image-hygiene assertion still passes.

 # Phase 19 Plan 05: Dev-Bypass Rework + Harness + CI Summary
 **One-liner:** Option C devSessionCookieMiddleware issues real local-session cookie under DEV_AUTH_BYPASS, break-glass reset-admin CLI, login.spec.ts real-form e2e, global-setup seeds local_credentials, and CI harness job gets LOCAL_SESSION_SECRET.
 ## Status: CHECKPOINT REACHED
 Task 4 is a `type="checkpoint:human-verify"` (gate="blocking"). Tasks 1-3 are complete and committed. The plan pauses for human confirmation that the full Playwright harness + CI run are green and that no dev artifact ships in the published image (D-15 boundary).
 ## Tasks Completed
 | Task | Name | Commit | Key Files |
 |------|------|--------|-----------|
 | 1 | Option C — devSessionCookieMiddleware | 3094df8 | devBypass.ts, index.ts |
 | 2 | Break-glass reset-admin CLI | 8239187 | apps/api/scripts/reset-admin.ts |
 | 3 | global-setup seed + login.spec.ts + CI env | 1f94dc5 | global-setup.ts, login.spec.ts, ci.yml + 7 test mocks |
 ## Task 4: Checkpoint (Pending Human Verification)
 **Checkpoint type:** `human-verify` (blocking)
 ### What was verified locally
 **API tests:** 446/446 tests pass (all 34 test files, including devBypass.test.ts: 3/3).
 **Typecheck:** `pnpm --filter @familysync/api typecheck` and `pnpm --filter @familysync/pwa typecheck` both exit 0.
 **reset-admin --dry-run:** Exit 0; no password value ("ignored") in output.
 **D-15 boundary verified:**
 - `.dockerignore` excludes `apps/api/scripts/` (reset-admin.ts never ships) — confirmed in file.
 - `.dockerignore` excludes `apps/pwa/e2e/` (global-setup seed never ships) — confirmed in file.
 - `devSessionCookieMiddleware()` production hard-guard is FIRST check (line 105 of devBypass.ts).
 - `reset-admin.ts` NODE_ENV=production throw is FIRST executable statement (line 26).
 - `LOCAL_SESSION_SECRET` in ci.yml is a documented dev-only value, never in the published image.
 **E2E login.spec.ts:** Cannot run locally yet — `LoginPage.tsx` is being produced by the concurrent plan 04 executor in the same wave. The spec is structurally correct (matches UI-SPEC selectors `id="login-username"`, `role="heading" name="Sign in"`, etc.) and will run as part of the full harness after wave 4 merges.
 ### What the human needs to verify
 1. **Push and run CI:** Push the branch → confirm the Gitea CI `harness` job is green. The harness job now includes `LOCAL_SESSION_SECRET` and the `local_credentials` seed step. The full Playwright suite (iphone + pixel + desktop) should pass including `login.spec.ts` on the desktop profile.
 2. **D-15 image boundary:** Confirm the `publish.yml` image-hygiene assertion still passes (no `apps/api/scripts/` or `apps/pwa/e2e/` artifacts in the published image). Spot-check `.dockerignore` covers both dirs.
 3. **Confirm login.spec.ts passes:** After wave 4 merges (plan 04 completes LoginPage.tsx), confirm `pnpm --filter @familysync/pwa test:e2e --grep "login"` exits 0 on the desktop profile.
 **Resume signal:** Type "approved" if the full harness + CI are green and no dev artifact ships.
 ## What Was Built
 ### Task 1: devSessionCookieMiddleware (Option C)
 **`apps/api/src/auth/devBypass.ts`** — new export `devSessionCookieMiddleware(): MiddlewareHandler`:
 - Production hard-guard FIRST check: `NODE_ENV === 'production'` → no-op (T-19-24, D-15)
 - No-op when `DEV_AUTH_BYPASS !== 'true'`
 - No-op when `LOCAL_SESSION_SECRET` not set (degrades gracefully)
 - When active: if no `local-session` cookie present, calls `issueLocalSessionCookie(c, DEV_USER.id)`
 - Imports: `getCookie` from hono/cookie, `issueLocalSessionCookie` from localSession.ts
 **`apps/api/src/index.ts`** — mounts `devSessionCookieMiddleware()` immediately after `devAuthBypass()` on `/api/*`.
 ### Task 2: reset-admin.ts (Break-Glass CLI)
 **`apps/api/scripts/reset-admin.ts`** — standalone break-glass CLI (149 lines):
 - NODE_ENV=production throw as FIRST executable statement (D-13/D-15)
 - `.dockerignore apps/api/scripts/` excludes it from the prod image (IMG-02)
 - Inline scrypt PHC `hashPassword()` (Pitfall 11 — cannot import compiled TS from plain script)
 - Parses `--username` / `--password` / `--dry-run` from process.argv
 - Upserts `users` row (is_admin=true, claimed=true) then upserts `local_credentials` row
 - Never logs the password value (T-19-26)
 - `--dry-run`: validates args + DB connection without writing; exit 0
 ### Task 3: global-setup seed + login.spec.ts + CI harness env
 **`apps/pwa/e2e/global-setup.ts`**:
 - Added `hashPasswordInline()` inline scrypt PHC (Pitfall 11 — plain Node.js)
 - Added `TRUNCATE TABLE local_credentials` to the TRUNCATE block
 - Added `INSERT INTO local_credentials (user_id, username, password_hash) VALUES (1, 'devuser', ?) ON DUPLICATE KEY UPDATE ...` after member_credentials seed
 **`apps/pwa/e2e/login.spec.ts`** (new, 98 lines):
 - Scoped to desktop/Chromium only (other profiles use bypass cookie)
 - Uses `context.clearCookies()` before each test to strip the bypass-issued cookie
 - Test 1: unauthenticated navigation → /login; brand + "Sign in" heading + form visible
 - Test 2: wrong password → `role="status"` shows "Incorrect username or password."
 - Test 3: devuser/devpass → navigates away from /login
 **`.gitea/workflows/ci.yml`** harness job:
 - Added new "Seed local_credentials for dev user (id=1)" step (CJS inline script with hashPassword)
 - Added `LOCAL_SESSION_SECRET: 'dev-secret-change-me-0000000000000000'` to harness env
 - LOCAL_SESSION_SECRET is a dev-only value, never in the published image (IMG gates)
 **Test mock fixes (Rule 1 — Bug):** Added `devSessionCookieMiddleware: () => async (_c, next) => next()` to all 7 `vi.mock('../../src/auth/devBypass.js', ...)` blocks that used an explicit factory return object (admin, setup, push, lists, localAuth, authMode, requireAdmin tests). `events.test.ts` uses `importOriginal` + spread and already picks up the new export automatically.
 ## Deviations from Plan
 ### Auto-fixed Issues
 **1. [Rule 1 - Bug] vitest mock missing devSessionCookieMiddleware export**
 - **Found during:** Task 3 — running the full API test suite after Task 1's devBypass.ts change
 - **Issue:** 7 test files mock `devBypass.js` with an explicit factory object. After adding `devSessionCookieMiddleware` to devBypass.ts, vitest reported "No `devSessionCookieMiddleware` export is defined on the mock" for every mock that did not include it.
 - **Fix:** Added `devSessionCookieMiddleware: () => async (_c, next) => next()` to all 7 explicit mock factories: admin.test.ts, setup.test.ts, push.test.ts (both `vi.mock` and `vi.doMock`), lists.test.ts, localAuth.test.ts, authMode.test.ts, requireAdmin.test.ts.
 - **Files modified:** 7 test files
 - **Commit:** 1f94dc5
 ## D-15 Guarantee
 | Artifact | Dev boundary | Enforcement |
 |----------|--------------|-------------|
 | `devSessionCookieMiddleware` | NODE_ENV=production hard-guard (FIRST check) + IMG-01 boot guard | T-19-24 |
 | `reset-admin.ts` | NODE_ENV=production throw (FIRST statement) + .dockerignore apps/api/scripts/ | T-19-25, IMG-02 |
 | `local_credentials` dev seed | Lives in apps/pwa/e2e/global-setup.ts (.dockerignore apps/pwa/e2e/) + CI step only | T-19-23 |
 | `LOCAL_SESSION_SECRET` in CI | Dev-only value in harness job env; never in Dockerfile or published image | IMG-01/02/03 |
 ## Known Stubs
 None. All new code performs real operations.
 ## Threat Surface Scan
 No new network endpoints introduced. New surface:
 - `devSessionCookieMiddleware`: internal middleware, no external exposure; guarded by NODE_ENV=production FIRST check (T-19-24).
 - `reset-admin.ts`: CLI only (docker exec), guarded by NODE_ENV=production throw + .dockerignore exclusion (T-19-25).
 All surfaces are within the plan's threat model (T-19-23 through T-19-26).
 ## Self-Check: PASSED
 All created files confirmed present on disk:
 - FOUND: apps/api/scripts/reset-admin.ts
 - FOUND: apps/pwa/e2e/login.spec.ts
 All commits confirmed in git log:
 - 3094df8: feat(19-05): Option C — devSessionCookieMiddleware issues real local-session cookie under bypass

 # Phase 19: Local Auth (No-OIDC Mode) - Context
 **Gathered:** 2026-06-16
 **Status:** Ready for planning
 <domain>
 ## Phase Boundary
 Let an operator run FamilySync entirely on **local DB username/password accounts with no OIDC/Authelia required**, while keeping OIDC available as an opt-in, generic (RFC-compliant, not Authelia-specific) provider that can be wired in later from the admin UI. Builds directly on the Phase-12 pre-OIDC local-user foundation (nullable `users.oidc_iss`/`oidc_sub`, the `claimed` marker, and the first-login-claims merge in `upsertUser`).
 **In scope:** local credential storage (scrypt) + local login flow; a new local login UI in the PWA; a stateless local-session cookie + middleware; coexistence with the existing OIDC middleware; admin-managed local account creation + password set/change/reset; per-user OIDC-link (replacing local for that user); de-Authelia-izing OIDC config/copy to a generic OIDC provider; a lockout/break-glass recovery mechanism; reworking dev-bypass + the Phase 7/8 Playwright harness to cover the new login UI.
 **Out of scope:** a full pluggable multi-auth-provider framework (LDAP, magic-link, multiple OIDC) — that is the auth-layer counterpart of backlog 999.1, a future phase. Email-based password reset (email is out of project scope). BYO-CalDAV provider abstraction (999.1, separate).
 </domain>
 <decisions>
 ## Implementation Decisions
 ### Mode & Coexistence
 - **D-01:** Local auth is the **default and always available**. OIDC is **opt-in/additive**, never a replacement for the local path at the system level.
 - **D-02:** OIDC is configured from the **admin UI** (extends the Phase-12 config that already lands in `app_config`: `oidc_issuer`, `oidc_client_id`, `app_external_url`). When OIDC is configured, **both methods are offered and the user chooses at login** (local username/password OR "Login with OIDC").
 - **D-03:** This must **not break the existing live OIDC deployment**. The two current household members already authenticate via Authelia (`oidc_iss`/`oidc_sub` set, `claimed=true`); they continue as OIDC users. Local auth is layered on additively.
 - **D-04:** A **new local login UI (username + password) must be built in the PWA** — none exists today. The PWA currently boots straight into the authed app (OIDC redirect) or via dev-bypass; there is no login form.
 ### Session Issuance
 - **D-05:** Local logins are backed by a **stateless signed httpOnly JWT cookie** carrying `userId`, validated by a **new local-auth middleware that sets `c.get('user')`** the same way `auth/devBypass.ts` does — so every downstream route resolves the user unchanged. **No DB sessions table** (consistent with the app's existing storage-less-JWT approach; right for household scale). Tradeoff accepted: a password change cannot retroactively invalidate other live sessions; logout = clear cookie.
 - **D-06 (BYO-Auth principle):** Local auth is first-class; OIDC is treated as a **generic RFC-compliant provider, not Authelia-hardcoded**. `@hono/oidc-auth` is already provider-agnostic — work is to de-Authelia-ize config keys and user-facing copy and treat issuer/client as generic OIDC config. Mirrors the planned BYO-CalDAV provider abstraction (999.1).
 - **D-07 (BYO-Auth scope):** Ship **local + one generic OIDC** with a **clean internal seam** for future methods. **No plugin/registry framework** in this phase.
 ### Password Hashing & Storage
 - **D-08:** Hash local passwords with **`node:crypto` scrypt** — zero new dependency, no native node-gyp build in the Docker image (honors the stack's deliberate no-native-dep stance, the same reason Drizzle was chosen over Prisma). Encode **algorithm + params + salt alongside the hash** so parameters can evolve. (argon2id/bcrypt native addons explicitly rejected.)
 - **D-09:** Store local credentials in a **new `local_credentials` table** — `user_id` (FK to `users`, UNIQUE), `username` (UNIQUE), `password_hash` (encoded), `createdAt`/`updatedAt` — mirroring the `member_credentials` pattern. Keeps the `users` row identity-method-agnostic. **Auth methods are a per-user property**: a user has local login iff a `local_credentials` row exists, and OIDC login iff an `oidc_iss+oidc_sub` binding exists. Drizzle **generate+migrate, never push** (additive migration on populated MariaDB — same rule as Phases 10/12).
 ### Accounts & OIDC-Link
 - **D-10:** **Admin creates members** + sets an initial password; the member changes it later. **No open self-signup** (wrong trust model for a private household app exposed via Pangolin).
 - **D-11:** Password lifecycle = **self-change (current + new) + admin-reset** from the admin UI. **No email reset** (email out of project scope). Reuses the admin surface that already rotates Fastmail app passwords.
 - **D-12:** **OIDC link replaces local at the per-user level**: when a local user links an OIDC identity (explicit action while authenticated as that user — never an email match, per Phase-12 D-10), **delete that user's `local_credentials` row** → they become OIDC-only. OIDC-only users never receive a local credential. The returned `iss+sub` must not already belong to another user.
 - **D-13 (break-glass):** Lockout recovery does **not** need to be a permanent local user account (avoids a member-vs-operator capability split — explicitly rejected). Instead, recovery is a **CLI/console command and/or env override** (e.g. create/reset a local admin, or disable/force-off OIDC), run on the host/container. **No new role/capability model**; reuse today's single `users.is_admin`. Exact form → researcher (see Open Questions).
 ### Testing & Dev-Bypass
 - **D-14:** The new login UI requires touching existing API/unit tests and the **Phase 7/8 Playwright harness** (which today reaches the authed PWA purely via `DEV_AUTH_BYPASS`, skipping any login). Both the already-authed fast path and the **real login form** must remain testable.
 - **D-15 (hard constraint):** Any seeded test login / reworked dev-bypass mechanism **stays dev-only and never ships in the Docker/prod image**. It is bound by the existing Phase-16 image-hygiene gates: the IMG-01 boot guard (`assertNotDevBypassInProduction`), `.dockerignore` (IMG-02), and the publish-time hygiene assertion (IMG-03). New dev-seed-login artifacts must be covered by those same gates.
 ### Claude's Discretion (decided in-discussion)
 - Session backing mechanism (chose stateless signed JWT cookie — D-05).
 - Credential storage location (chose separate `local_credentials` table — D-09).
 These were "you decide" responses; rationale captured above. Researcher/planner may refine implementation detail but should not reverse the locked choice without cause.
 </decisions>
 <canonical_refs>
 ## Canonical References
 **Downstream agents MUST read these before planning or implementing.**
 ### Auth foundation this phase extends
 - `apps/api/src/auth/user.ts` — `upsertUser` (identity = `oidc_iss+oidc_sub`, never email; first-login-claims of the single unclaimed row; first-login-wins `is_admin` bootstrap; `claimed` semantics). The local-account + OIDC-link model generalizes this.
 - `apps/api/src/auth/middleware.ts` — OIDC middleware wiring + `oidcConfigFallbackMiddleware` (env-OR-`app_config` fallback for `OIDC_ISSUER`/`OIDC_CLIENT_ID`/`app_external_url`). The generic-OIDC config path lives here.
 - `apps/api/src/auth/devBypass.ts` — `devAuthBypass()` + `DEV_USER`; the `c.set('user', …)` pattern the new local-auth middleware mirrors. Subject of the dev-bypass rework (D-14/D-15).
 - `apps/api/src/auth/persistSessionCookie.ts` — session-cookie persistence helper (referenced by the session model).
 - `apps/api/src/index.ts` — middleware mount order (`/api/setup` pre-auth → `devAuthBypass` → `oidcConfigFallback` → `oidcAuthMiddleware` → `persistSessionCookie`); `devBypassActive` computed once at boot; `assertNotDevBypassInProduction()` boot guard. Local-login routes + middleware slot in here.
 - `apps/api/src/routes/me.ts` — `resolveUserId` (dev-bypass `c.get('user')` first, else `getAuth`) + `needsProviderSetup`/`isAdmin` exposure. The user-resolution seam for all routes.
 - `apps/api/src/db/schema.ts` — `users` (nullable `oidc_iss`/`oidc_sub`, `claimed`, `is_admin`, `uniq_oidc_identity`), `member_credentials` (pattern to mirror for `local_credentials`), `app_config` (k/v config; PROHIBITION list for secrets-in-DB).
 - `apps/api/src/routes/admin.ts` + `apps/api/src/lib/requireAdmin.ts` — admin route surface + role guard the account-management UI and OIDC config UI extend.
 - `apps/api/src/routes/setup.ts` + `apps/api/src/lib/setupGuard.ts` — Phase-12 pre-auth wizard + 423 lock; the first-local-admin bootstrap replaces the current unclaimed-user provisioning.
 ### Image hygiene / dev-prod boundary (constrains D-15)
 - `apps/api/src/lib/bootGuards.ts` — `assertNotDevBypassInProduction` (IMG-01).
 - `.dockerignore` (repo root) — IMG-02 dev-artifact exclusion.
 - `.gitea/workflows/publish.yml` — IMG-03 publish-time image-hygiene + boot-smoke assertions.
 ### Test harness this phase must update
 - `apps/pwa/playwright.config.ts` + `apps/pwa/e2e/` (global-setup deterministic mysql2 seed, `layout.spec.ts`, `calendar.spec.ts`, `lists.spec.ts`) — Phase 7 harness; auth reached via `DEV_AUTH_BYPASS`.
 - `.gitea/workflows/ci.yml` — CI `harness` job (brings up dev stack with `DEV_AUTH_BYPASS=true`).
 ### Provenance / prior decisions
 - `.planning/phases/12-initial-setup-wizard/12-CONTEXT.md` §Deferred Ideas — origin of this phase (full local-auth/no-OIDC mode deferred from Phase 12; D-07 local-user groundwork is the deliberate foundation).
 - `.planning/ROADMAP.md` §"Phase 19" — goal, dependency on Phase 12, and the four seed open questions.
 - `.planning/PROJECT.md` §Constraints / §Auth — Authelia-OIDC constraint context; MariaDB-only; no-native-dep stance.
 </canonical_refs>
 <code_context>
 ## Existing Code Insights
 ### Reusable Assets
 - `member_credentials` table shape + `validateEncryptAndStoreCredential` flow (`broker/credentialSync.ts`) — direct template for the `local_credentials` table and an admin-managed create/reset write path.
 - `devAuthBypass()`'s `c.set('user', …)` pattern — the new local-auth middleware reuses it so downstream routes (`resolveUserId` in every router) need no change.
 - `oidcConfigFallbackMiddleware` (env-OR-`app_config`) — the established pattern for admin-UI-written OIDC config taking effect.
 - Phase-12 `upsertUser` claim/link machinery — the OIDC-link flow (D-12) is a generalization (bind `iss+sub` to an already-authenticated local user, then drop their local credential).
 - `assertNotDevBypassInProduction` + `.dockerignore` + `publish.yml` hygiene assertions — the enforcement surface for D-15.
 ### Established Patterns
 - **Identity = `oidc_iss+oidc_sub`, never email** (Phase-12 D-10) — local accounts are a separate per-user credential, and OIDC-link must be explicit (no email matching).
 - **Drizzle generate+migrate, never push** — additive migration on populated MariaDB (Phases 10/12 precedent); applies to the new `local_credentials` table.
 - **`is_admin` is the server boundary; client `isAdmin` is UX-only** — local-auth admin gating reuses `requireAdmin`.
 - **Secrets stay in env, never in `app_config`/DB** (Phase-12 PROHIBITION) — the local-session signing secret and scrypt config live in env, not the DB.
 - **Storage-less JWT session cookie** (CLAUDE.md, `@hono/oidc-auth`) — the local-session cookie follows the same stateless philosophy (D-05).
 ### Integration Points
 - New local-login routes + local-auth middleware mount in `index.ts` alongside (and ordered against) `devAuthBypass`/`oidcAuthMiddleware`; the OIDC guard must not 302-redirect local-mode requests.
 - The PWA gate (App.tsx setup/login routing) gains a login screen and a login-vs-OIDC chooser; `/api/me` / a new auth-mode endpoint tells the PWA which methods to offer.
 - Setup wizard bootstrap shifts from "provision one unclaimed user" to "create the first local admin (username+password)".
 </code_context>
 <specifics>
 ## Specific Ideas
 - "Bring Your Own Auth" framing (user's words) — explicitly do not pigeon-hole into Authelia; OIDC is one generic provider, parallel to the intended "Bring Your Own CalDAV provider" direction (999.1).
 - User leans toward **"replace dev-bypass with seeded auto-login"** for the harness, but defers the final call to the researcher.
 - User prefers the **break-glass to be a CLI/env override rather than a user account**, to avoid added user/capability complexity.
 </specifics>
 <deferred>
 ## Deferred Ideas
 - **Full pluggable auth-provider framework** (registry/plugin for LDAP, magic-link, multiple simultaneous OIDC providers) — auth-layer counterpart of backlog 999.1; its own future phase/milestone. Phase 19 builds only a clean internal seam.
 - **Member-vs-operator capability/role split** — considered for the break-glass account, explicitly rejected in favor of a CLI/env recovery mechanism + the existing single `is_admin` flag.
 - **Email-based password reset** — out of project scope (no email features).
 ## Open Questions for Research
 - **Dev-bypass rework (decide among 3):** (a) keep bypass + seed a real test login for login-specific specs; (b) replace bypass with seeded auto-login through the real local flow (user's lean); (c) bypass auto-issues a real local-session cookie. Must satisfy D-14 + the D-15 dev-only/no-prod-image constraint.
 - **Break-glass recovery form:** CLI/console command vs env override (or both) for create/reset-local-admin and/or disable-OIDC; how it interacts with the boot-time mode/middleware selection.
 - **OIDC-only user provisioning:** how an OIDC-only user is first created given D-10 forbids email-matching unclaimed rows — just-in-time on first OIDC login vs admin pre-creation + claim (the Phase-12 single-unclaimed-row claim can't disambiguate multiple pre-created placeholders).
 - **Login-vs-OIDC mode signalling to the PWA:** reuse/extend `/api/me` or `/api/setup/status`, or a new pre-auth `/api/auth/mode` endpoint, so the login page knows which methods to render.
 - **Local-login hardening:** rate-limiting / lockout / timing-safe compare on the local login endpoint (household scale, but Pangolin-exposed).

 # Phase 19: Local Auth (No-OIDC Mode) - Discussion Log
 > **Audit trail only.** Do not use as input to planning, research, or execution agents.
 > Decisions are captured in CONTEXT.md — this log preserves the alternatives considered.
 **Date:** 2026-06-16
 **Phase:** 19-local-auth-no-oidc-mode
 **Areas discussed:** Mode & coexistence, Session issuance, Password hashing & storage, Accounts & OIDC-link, Testing & dev-bypass
 ---
 ## Mode & Coexistence
 ### Q1 — How should the app decide between local-auth and OIDC?
 | Option | Description | Selected |
 |--------|-------------|----------|
 | app_config flag (runtime) | `auth_mode` row in app_config, set by wizard; no restart | |
 | Deploy-time env switch | `AUTH_MODE` env read at boot | |
 | Both always live | Local form + OIDC button always shown | |
 **User's choice:** Free-text — "Default to local and add the ability to wire OIDC in later if wanted."
 **Notes:** Local is the always-available default; OIDC is additive/opt-in.
 ### Q2 — How does the app know OIDC is wired in, and what happens to local login?
 | Option | Description | Selected |
 |--------|-------------|----------|
 | Auto-detect, local stays live | OIDC on when config present; local always available | (partial) |
 | Auto-detect, OIDC takes over | Local disabled once OIDC present | |
 | Explicit app_config toggle | Separate `auth_mode` controlled from admin UI | (partial) |
 **User's choice:** Free-text — OIDC config is set/stored in a later step, so wire it into the **admin UI**; give users the choice of which to use at login; **no local login UI exists today** so it must be built.
 **Notes:** Blend — admin-UI-configured OIDC, both methods offered at login, user chooses.
 ---
 ## Session Issuance
 ### Q1 — What backs a local login session?
 | Option | Description | Selected |
 |--------|-------------|----------|
 | Stateless signed JWT cookie | userId in signed httpOnly cookie; no DB table | ✓ (Claude) |
 | Server-side session table | sessions table for true revocation | |
 | You decide | — | ✓ |
 **User's choice:** "You decide" + "do not pigeon-hole the user into Authelia — Bring Your Own Auth and Bring Your Own CalDAV provider."
 **Notes:** Claude chose stateless signed JWT cookie. User added the BYO-Auth architectural principle (generic OIDC, not Authelia-locked).
 ### Q2 — How far should the BYO-Auth abstraction go in Phase 19?
 | Option | Description | Selected |
 |--------|-------------|----------|
 | Local + generic OIDC | Two concrete methods, clean seam, no framework | ✓ |
 | Full pluggable framework | Provider registry/plugin (LDAP, magic-link, multi-OIDC) | |
 | Local only for now | Leave Authelia OIDC as-is, defer generic OIDC | |
 **User's choice:** Local + generic OIDC (recommended).
 **Notes:** Clean internal seam now; full framework deferred.
 ---
 ## Password Hashing & Storage
 ### Q1 — Which password hashing approach?
 | Option | Description | Selected |
 |--------|-------------|----------|
 | scrypt via node:crypto | Stdlib, zero-dep, no native build | ✓ |
 | argon2id (native dep) | OWASP top pick, needs native addon | |
 | bcrypt (bcryptjs) | Pure JS, older KDF | |
 **User's choice:** scrypt via node:crypto (recommended).
 **Notes:** Honors the stack's no-native-dep stance.
 ### Q2 — Where to store username + hash?
 | Option | Description | Selected |
 |--------|-------------|----------|
 | Separate local_credentials table | Mirrors member_credentials; user-agnostic users row | ✓ (Claude) |
 | Columns on users | Add username + password_hash to users | |
 | You decide | — | ✓ |
 **User's choice:** "You decide."
 **Notes:** Claude chose a separate `local_credentials` table — best fits the BYO-Auth per-user-method seam (one row can hold both a local credential and an OIDC binding).
 ---
 ## Accounts & OIDC-Link
 ### Q1 — How are local accounts created?
 | Option | Description | Selected |
 |--------|-------------|----------|
 | Admin creates members | Wizard creates first admin; admin creates rest | ✓ |
 | Admin creates + invite link | One-time set-password link | |
 | Open self-signup | Anyone can register | |
 **User's choice:** Admin creates members.
 ### Q2 — Password change/reset?
 | Option | Description | Selected |
 |--------|-------------|----------|
 | Self-change + admin reset | Member self-change; admin resets lockouts | ✓ |
 | Self-change only | No admin reset | |
 | Admin reset only | No self-change | |
 **User's choice:** Self-change + admin reset.
 **Notes:** No email reset (email out of scope).
 ### Q3 — After OIDC-link, what methods stay valid? (reformulated after clarification)
 | Option | Description | Selected |
 |--------|-------------|----------|
 | Both stay valid | Row holds local + OIDC; either logs in | |
 | OIDC primary, local fallback | Same data model, UI emphasis on OIDC | |
 | OIDC replaces local | Linking removes local credential | ✓ (per user) |
 **User's choice:** Initially requested clarification; then chose **OIDC replaces local per user** — there can/should be OIDC-only users with no local creds. Raised the need for a break-glass path.
 **Notes:** Auth methods are per-user (presence of local_credentials row and/or OIDC binding). Break-glass need surfaced here.
 ### Q4 — Break-glass capability model?
 | Option | Description | Selected |
 |--------|-------------|----------|
 | Protected local admin (no new role model) | Initial admin, un-removable local cred | |
 | Operator-only account (member/operator split) | Strip member capability from break-glass | |
 | Let researcher scope it | Lock the requirement, defer the how | ✓ (twist) |
 **User's choice:** Let researcher scope it — **with a twist: break-glass can be a CLI/console command or env override instead of a user**, removing the added-user/capability complexity.
 **Notes:** No new role/capability model; reuse `is_admin`. Recovery mechanism (not account) to be scoped by researcher.
 ---
 ## Testing & Dev-Bypass (added mid-discussion at user's request)
 ### Q1 — How should DEV_AUTH_BYPASS evolve?
 | Option | Description | Selected |
 |--------|-------------|----------|
 | Bypass stays + seed a real test login | Fast bypass for most specs; real form for login specs | |
 | Replace bypass with seeded auto-login | Harness logs in via real local flow | (user's lean) |
 | Bypass auto-issues a real local session | Bypass logs in seeded user, skips form | |
 **User's choice:** Defer final determination to the **research agent**; user **leans toward "replace bypass with seeded auto-login."**
 **Notes:** Hard constraint — the seeded test login / dev-bypass **stays dev-only and never ships in the Docker/prod image** (Phase 16 IMG-01/02/03 gates apply).
 ---
 ## Claude's Discretion
 - Local session backing → stateless signed JWT cookie (D-05).
 - Credential storage location → separate `local_credentials` table (D-09).
 ## Deferred Ideas
 - Full pluggable auth-provider framework (registry/plugin; LDAP, magic-link, multi-OIDC) — future phase, counterpart of 999.1.
 - Member-vs-operator capability/role split — rejected in favor of CLI/env break-glass recovery.
 - Email-based password reset — out of project scope.

 # Phase 19: Code Review Fix Report
 **Fixed at:** 2026-06-17T20:39:00Z
 **Source review:** .planning/phases/19-local-auth-no-oidc-mode/19-REVIEW.md
 **Iteration:** 1
 **Summary:**
 - Findings in scope: 15 (4 critical, 4 blocker, 7 warning, 4 info — fix_scope: all)
 - Fixed: 15
 - Skipped: 0
 **Verification:** Full API suite **452/452** (34 files, live MariaDB) and full PWA suite **266/266** (22 files) pass; both `tsc --noEmit` clean. Findings classified as security/availability logic (CR-04, BL-03, WR-06, IN-04) are flagged "requires human verification" below — syntax/tests pass but a human should confirm the threat-model intent.
 ## Fixed Issues
 ### CR-01: OIDC-link flow broken — client/server response-shape mismatch
 **Files modified:** `apps/pwa/src/api/client.ts`, `apps/pwa/src/components/SettingsSheet.tsx`
 **Commit:** 1688f22
 **Applied fix:** Changed `fetchLinkOidc` to return `{ authorizationUrl: string | null }` matching the server's `{ signedState, authorizationUrl }` contract, and updated `LinkOidcSheet` to navigate to `authorizationUrl` (handling the `null`/unconfigured case by surfacing an error instead of navigating to `undefined`).
 ### CR-02: Admin "create member" always fails — request field-name mismatch
 **Files modified:** `apps/pwa/src/api/client.ts`
 **Commit:** 93c47b3
 **Applied fix:** `fetchCreateMember` now sends `initialPassword` (the field `createMemberSchema` requires) instead of `password`, and maps HTTP 409 to `Error('conflict')` so the AdminPage's existing conflict branch renders the right banner.
 ### CR-03: Self-service password change logs user out on wrong current password
 **Files modified:** `apps/api/src/routes/me.ts`, `apps/pwa/src/api/client.ts`, `apps/api/tests/routes/me.test.ts`
 **Commit:** 6ef8e03
 **Applied fix:** Server returns **403** (not 401) for an incorrect current password; client `fetchChangePassword` branches on 403 → `Error('wrong-current')` before the 401→`SessionExpiredError` path, so a mistyped password no longer triggers the global session-expiry logout. Updated me.test Test 2 to expect 403.
 ### CR-04: Login lockout per-IP, global, permanent, unrecoverable — *requires human verification*
 **Files modified:** `apps/api/src/routes/localAuth.ts`, `apps/api/src/routes/admin.ts`, `apps/pwa/src/routes/LoginPage.tsx`, `apps/api/tests/routes/localAuth.test.ts`
 **Commit:** b083cb7
 **Applied fix:** Re-scoped the rate limiter from client IP to the **validated username**; added a **15-minute TTL** so a 423 lockout auto-expires (self-healing, no restart); wired admin password-reset to call `resetLoginAttempts(username)` for an immediate unlock; corrected the LoginPage banner copy. Added Test 5b asserting TTL auto-expiry. *Human verification: confirm the username-scoping + TTL behaviour matches the intended threat model for the tunnel deployment.*
 ### BL-01: devSessionCookieMiddleware issues a session without verifying secret strength
 **Files modified:** `apps/api/src/auth/devBypass.ts`
 **Commit:** 3674b25
 **Applied fix:** Apply the same `secret.length >= 32` floor used by the boot guard inside `devSessionCookieMiddleware` before minting the dev cookie (degrade to no-op if too short), and emit a loud warning when the secret is the well-known dev placeholder.
 ### BL-02: Logout cannot clear the cookie in non-production (Secure attribute mismatch)
 **Files modified:** `apps/api/src/auth/localSession.ts`
 **Commit:** cd095e5
 **Applied fix:** `clearLocalSessionCookie` now mirrors the issue-time `secure: process.env.NODE_ENV === 'production'` logic instead of hard-coding `secure: true`, so the deletion cookie is accepted over plain HTTP and logout actually clears the session in HTTP-only self-hosts.
 ### BL-03: OIDC-link binding swallows failure / binds on stale/blank identity — *requires human verification*
 **Files modified:** `apps/api/src/index.ts`
 **Commit:** 7153760
 **Applied fix:** In the `/callback` link path, reject the bind unless the current local session (`verifyLocalSessionCookie`) matches `linkUserId` (account-takeover guard), and reject when `iss`/`sub` are empty (never call `linkOidcToUser` with blank identity, which would corrupt identity and delete the user's local credential). *Human verification: confirm the session cross-check closes the replay-takeover path described in the review.*
 ### BL-04: localAuthMiddleware fabricates oidcSub collisions for local users
 **Files modified:** `apps/api/src/auth/devBypass.ts`, `apps/api/src/auth/localAuthMiddleware.ts`, `apps/api/tests/auth/localAuthMiddleware.test.ts`
 **Commit:** 40666e1
 **Applied fix:** Introduced a `ContextUser` interface with nullable `oidcIss`/`oidcSub`; the middleware now stores `null` for local users instead of the `'local'`/`String(id)` sentinels that shared the `uniq_oidc_identity` uniqueness domain. Added Test 1c asserting null context for a null-OIDC local user.
 ### WR-01: reset-admin.ts arg parsing trusts `--password ''` and echoes username
 **Files modified:** `apps/api/scripts/reset-admin.ts`
 **Commit:** c4d8d76
 **Applied fix:** Rewrote `parseArgs` to support `--key=value` and to treat `--username`/`--password` as value-taking (consuming the next token verbatim, so a `--`-prefixed or empty password is preserved) and `--dry-run` as boolean; removed username interpolation from log lines.
 ### WR-02 + WR-04: hardcoded Authelia auth path / OIDC-config detection divergence
 **Files modified:** `apps/api/src/auth/oidcConfig.ts` (new), `apps/api/src/routes/me.ts`
 **Commit:** 322929a
 **Applied fix:** New `oidcConfig.ts` centralizes the env-OR-app_config resolution (`resolveOidcConfig`) and discovers the `authorization_endpoint` from the provider's `/.well-known/openid-configuration` (`discoverAuthorizationEndpoint`). me.ts link-oidc now uses both, so a wizard-configured instance no longer reports `oidcEnabled:true` while returning `authorizationUrl:null`, and the URL is no longer Authelia-path-specific. (Two findings fixed in one commit — they share the same handler/lines and are inseparable.)
 ### WR-03: scryptSync blocks the event loop on the login hot path
 **Files modified:** `apps/api/src/auth/localCredentials.ts`, `apps/api/src/routes/localAuth.ts`, `apps/api/src/routes/me.ts`, `apps/api/src/routes/admin.ts`, plus their tests
 **Commit:** 30ad25c
 **Applied fix:** Converted `hashPassword`/`verifyPassword` to async (threadpool scrypt via a typed Promise wrapper), awaited at all call sites, made the login DUMMY_HASH a module-level promise, and moved create-member hashing outside the DB transaction. Updated all test call sites to await. Preserves the timing-defense property while keeping the event loop responsive.
 ### WR-05: noEchoHook pass-through is correct-but-untested
 **Files modified:** `apps/api/tests/routes/admin.test.ts`, `apps/api/tests/routes/me.test.ts`
 **Commit:** 4bd6b2c
 **Applied fix:** Added focused no-echo tests for the admin create-member and me password hook sites asserting a malformed body never includes the submitted password or Zod's `received`/`issues`. `@hono/zod-validator` is already pinned to exact `0.8.0` in package.json.
 ### WR-06: rate-limit lockedUntil refreshed on every blocked attempt — *requires human verification*
 **Files modified:** `apps/api/src/routes/localAuth.ts`
 **Commit:** 4cf2ad4
 **Applied fix:** The 429 (already-rejected) branch no longer re-arms `lockedUntil`; the cooldown window stays anchored to when it was first armed, so sustained attacker traffic can no longer slide the window forward indefinitely. *Human verification: confirm the window now expires on schedule for a legitimate user behind the same identity.*
 ### WR-07: parseInt member/calendar id accepts trailing garbage
 **Files modified:** `apps/api/src/routes/admin.ts`, `apps/api/tests/routes/admin.test.ts`
 **Commit:** 32bdd1e
 **Applied fix:** Added `parsePositiveIntParam` using `Number.isInteger(Number(raw))` and applied it to `/members/:id/password` and `/calendars/:id/shared`, so `"12abc"` is now rejected with 400. Added a test for the calendar route.
 ### IN-01: localSession maxAge/expiry parsing has no validation
 **Files modified:** `apps/api/src/auth/localSession.ts`
 **Commit:** f2fc140
 **Applied fix:** Coerce and validate `LOCAL_SESSION_EXPIRES` — fall back to 86400s for any non-finite or non-positive value, preventing a `NaN` exp/maxAge.
 ### IN-02: duplicated inline scrypt implementation across three locations
 **Files modified:** `apps/api/tests/auth/localCredentials.test.ts`
 **Commit:** e392bf2
 **Applied fix:** Added a lockstep test that builds a hash using the inlined scrypt parameters (N=16384, r=8, p=1, KEY_LEN=32 — matching reset-admin.ts and ci.yml) and asserts it round-trips against the canonical `verifyPassword`, so a parameter drift fails CI loudly.
 ### IN-03: loginAttempts map is unbounded
 **Files modified:** `apps/api/src/routes/localAuth.ts`
 **Commit:** f02521d
 **Applied fix:** Added `evictStaleLoginAttempts`, called opportunistically per login request, dropping entries that are neither in an active rate-limit window nor an active lockout TTL — bounding the map under input churn without weakening the limiter.
 ### IN-04: link-oidc nonce generated but never persisted/verified — *requires human verification*
 **Files modified:** `apps/api/src/auth/linkNonceStore.ts` (new), `apps/api/src/routes/me.ts`, `apps/api/src/index.ts`
 **Commit:** 2691dd0
 **Applied fix:** New in-memory single-use nonce store: me.ts registers the issued nonce (valid until the state JWT's exp); the `/callback` link path consumes it and rejects any replayed/unknown/expired nonce before binding. Combined with BL-03's session cross-check, the captured-state replay window is closed. *Human verification: confirm single-use semantics are sufficient for the single-process deployment (move to Redis if multi-process).*

 ### WR-07: parseInt member/calendar id accepts trailing garbage
 **Files modified:** `apps/api/src/routes/admin.ts`, `apps/api/tests/routes/admin.test.ts`
 **Commit:** 32bdd1e
 **Applied fix:** Added `parsePositiveIntParam` using `Number.isInteger(Number(raw))` and applied it to `/members/:id/password` and `/calendars/:id/shared`, so `"12abc"` is now rejected with 400. Added a test for the calendar route.
 ### IN-01: localSession maxAge/expiry parsing has no validation
 **Files modified:** `apps/api/src/auth/localSession.ts`
 **Commit:** f2fc140
 **Applied fix:** Coerce and validate `LOCAL_SESSION_EXPIRES` — fall back to 86400s for any non-finite or non-positive value, preventing a `NaN` exp/maxAge.
 ### IN-02: duplicated inline scrypt implementation across three locations
 **Files modified:** `apps/api/tests/auth/localCredentials.test.ts`
 **Commit:** e392bf2
 **Applied fix:** Added a lockstep test that builds a hash using the inlined scrypt parameters (N=16384, r=8, p=1, KEY_LEN=32 — matching reset-admin.ts and ci.yml) and asserts it round-trips against the canonical `verifyPassword`, so a parameter drift fails CI loudly.
 ### IN-03: loginAttempts map is unbounded
 **Files modified:** `apps/api/src/routes/localAuth.ts`
 **Commit:** f02521d
 **Applied fix:** Added `evictStaleLoginAttempts`, called opportunistically per login request, dropping entries that are neither in an active rate-limit window nor an active lockout TTL — bounding the map under input churn without weakening the limiter.
 ### IN-04: link-oidc nonce generated but never persisted/verified — *requires human verification*
 **Files modified:** `apps/api/src/auth/linkNonceStore.ts` (new), `apps/api/src/routes/me.ts`, `apps/api/src/index.ts`
 **Commit:** 2691dd0
 **Applied fix:** New in-memory single-use nonce store: me.ts registers the issued nonce (valid until the state JWT's exp); the `/callback` link path consumes it and rejects any replayed/unknown/expired nonce before binding. Combined with BL-03's session cross-check, the captured-state replay window is closed. *Human verification: confirm single-use semantics are sufficient for the single-process deployment (move to Redis if multi-process).*

 # Phase 19: Code Review Report
 **Reviewed:** 2026-06-17
 **Depth:** deep
 **Files Reviewed:** 39 (auth source + routes + PWA + CI)
 **Status:** issues_found
 ## Summary
 Phase 19 adds a local username/password authentication mode alongside the existing
 OIDC flow. The cryptographic core (scrypt PHC hashing, constant-time compare, dummy-hash
 timing defense, HS256 session JWT with boot guards) is implemented carefully and is sound.
 The middleware chain (`devAuthBypass → devSessionCookie → localAuthMiddleware → OIDC guard`)
 and the admin-privilege boundary (`requireAdmin` DB-enforced on every `/api/admin/*` request)
 are correct.
 The serious problems are at the **client↔server API contract boundary** — the exact place
 a deep cross-file review is meant to catch. Three Phase-19 client functions in
 `apps/pwa/src/api/client.ts` disagree with their server routes on field names, response
 shape, or status-code handling, so the corresponding features (OIDC-link, admin
 create-member, and self-service password change error handling) are broken end-to-end
 despite each side individually passing its own unit tests. There is also an
 authentication availability defect: the per-IP login lockout is mislabeled as
 "account locked," is global, and never expires — a single attacker IP can permanently
 deny login for the whole household with no self-recovery path.
 ## Critical Issues
 ### CR-01: OIDC-link flow is broken — client/server response-shape mismatch
 **File:** `apps/pwa/src/api/client.ts:226-238` and `apps/api/src/routes/me.ts:301-341`
 **Issue:** `fetchLinkOidc()` reads `result.redirectUrl` and its return type is
 `{ redirectUrl: string }`. The server's `POST /api/me/link-oidc` returns
 `{ signedState, authorizationUrl }` — there is no `redirectUrl` key. The caller
 (Surface 13 "Link OIDC") will navigate to `undefined`, so the entire OIDC-link feature
 (AUTH-LOCAL-10) cannot work in the browser. Each side's own unit tests pass because
 neither test crosses the boundary. Additionally `authorizationUrl` can legitimately be
 `null` (OIDC unconfigured), which the client type does not model.
 **Fix:** Make the contract agree. Either return `redirectUrl` from the server, or read
 `authorizationUrl` on the client and handle `null`:
 ```ts
 export async function fetchLinkOidc(): Promise<{ authorizationUrl: string | null }> {
  // ...
  return res.json() as Promise<{ signedState: string; authorizationUrl: string | null }>;
 }
 // caller:
 const { authorizationUrl } = await fetchLinkOidc();
 if (authorizationUrl) window.location.href = authorizationUrl;
 ```
 ### CR-02: Admin "create member" always fails — request field-name mismatch
 **File:** `apps/pwa/src/api/client.ts:176-194` and `apps/api/src/routes/admin.ts:123-133`
 **Issue:** `fetchCreateMember` POSTs `{ displayName, username, password }`. The server's
 `createMemberSchema` requires `{ displayName, username, initialPassword }`. The `password`
 field is ignored and `initialPassword` is missing, so Zod validation fails and the route
 returns `400 { error: 'Invalid request' }` (via `noEchoHook`) for *every* valid admin
 attempt to create a local member (AUTH-LOCAL-07). The Admin UI maps a non-409 error to
 the generic "Something went wrong" banner, so the admin can never create an account.
 **Fix:** Send the field the server expects:
 ```ts
 body: JSON.stringify({
  displayName: body.displayName,
  username: body.username,
  initialPassword: body.password,
 }),
 ```
 ### CR-03: Self-service password change logs the user out on a wrong current password
 **File:** `apps/pwa/src/api/client.ts:148-165` and `apps/api/src/routes/me.ts:233-261`
 **Issue:** `fetchChangePassword` treats `res.status === 401` as `SessionExpiredError`,
 which the global MutationCache handler interprets as "session expired → arm the
 re-auth interstitial / redirect to login." But `POST /api/me/password` returns **401**
 `{ error: 'Current password incorrect' }` when the supplied current password is wrong
 (me.ts:259-260). So a user who simply mistypes their current password is forcibly logged
 out instead of seeing "current password incorrect." The client doc comment even claims
 "401 → wrong current password" while the code routes 401 to `SessionExpiredError`. The
 documented 422 validation branch also never fires — the server returns 400 (noEchoHook)
 or 404, not 422.
 **Fix:** Distinguish auth-expiry from an in-app 401. Have the route return a distinct
 status for "wrong current password" (e.g. 403 or a body code), and branch on it client-side
 before treating 401 as session expiry:
 ```ts
 if (res.status === 401) {
  const body = await res.json().catch(() => ({}));
  if (body?.error === 'Current password incorrect') throw new Error('wrong-current');
  throw new SessionExpiredError();
 }
 ```
 ### CR-04: Login lockout is per-IP, global, permanent, and unrecoverable
 **File:** `apps/api/src/routes/localAuth.ts:55-140`
 **Issue:** Multiple correctness/availability defects in one mechanism:
 1. The `loginAttempts` map is keyed by **IP**, yet the 423 response and the PWA banner say
   "This account is temporarily locked." It is neither account-scoped nor temporary.
 2. Once `count >= LOCKOUT_FAILURES (10)`, `lockedOut` is set permanently. The only documented
   clear path is "admin password reset" — but no admin route ever clears `loginAttempts`
   (admin.ts reset-password updates the hash, not the in-memory map). So **the lockout is
   genuinely unrecoverable without a process restart**.
 3. Because it is per-IP and all household traffic arrives via the Pangolin tunnel with the
   same `X-Forwarded-For` first hop, one bad actor (or one user fat-fingering 10 times) can
   lock out **every** member at that egress IP. This is a self-inflicted DoS on a 2-person
   household whose entire reason for existing is low-friction access.
 4. `X-Forwarded-For` is attacker-controllable on any request that does not pass through the
   trusted proxy; an attacker can rotate the header to get unlimited fresh rate-limit
   buckets, defeating the brute-force defense entirely while still being able to lock
   *other* identities by spoofing their IP if it were ever known.
 **Fix:** Re-scope the limiter to the submitted username (not IP), make the 423 lockout
 expire on a timer (or actually wire admin reset to clear it), correct the banner copy, and
 only trust `X-Forwarded-For` when the request demonstrably came from the known proxy
 (or use the leftmost-trusted hop). At minimum, give the lockout a TTL so a restart is not
 required:
 ```ts
 // derive key from the validated username, and expire lockout after N minutes
 const LOCKOUT_TTL_MS = 15 * 60 * 1000;
 if (attempt?.lockedOut && Date.now() < attempt.lockedUntil) { /* 423 */ }
 ```
 ## Blockers
 ### BL-01: `devSessionCookieMiddleware` issues a session for user id=1 without verifying the user exists or the secret is strong
 **File:** `apps/api/src/auth/devBypass.ts:102-131` and `apps/api/src/lib/bootGuards.ts:53-66`
 **Issue:** In dev-bypass mode the boot guard `assertLocalSessionSecretSet()` is *skipped*
 entirely (returns early when `DEV_AUTH_BYPASS==='true'`). `devSessionCookieMiddleware` then
 only checks that `LOCAL_SESSION_SECRET` is *present* (truthy), not that it is ≥32 chars, and
 mints a real, fully-valid `local-session` JWT for `DEV_USER.id (=1)`. The CI sets a weak
 fixed secret `'dev-secret-change-me-0000000000000000'`. Any cookie minted under bypass is a
 genuine, signature-valid session token for user 1 — if that same weak/known secret is ever
 present in a non-bypass environment (e.g. an operator copies the dev compose), forged
 sessions are trivial. The hard `NODE_ENV==='production'` guard mitigates the worst case, but
 this is a latent footgun: the boot guard's length check is the documented defense and it is
 bypassed here.
 **Fix:** Apply the same `secret.length >= 32` floor inside `devSessionCookieMiddleware`
 before issuing, and emit a loud warning if the dev secret is the placeholder value. Do not
 treat "present" as "safe."
 ### BL-02: Logout cannot clear the cookie in non-production (attribute mismatch)
 **File:** `apps/api/src/auth/localSession.ts:53-59` vs `97-106`
 **Issue:** `issueLocalSessionCookie` sets `secure: process.env.NODE_ENV === 'production'`
 (i.e. `secure:false` in dev/test over HTTP). `clearLocalSessionCookie` hard-codes
 `secure: true`. Browsers require the `Secure` attribute on a deletion cookie to match the
 context: over plain HTTP a `Secure` delete-cookie is rejected, so `POST /local/logout`
 returns 200 but the `local-session` cookie is **not actually cleared** in any non-HTTPS
 deployment (local dev, and any HTTP-only self-host). The user appears logged in after
 "logout." The inline comment acknowledges the mismatch but waves it away with "logout should
 happen over HTTPS" — that is an unsafe assumption for a self-hosted app that explicitly
 supports private-IP/HTTP internal access.
 **Fix:** Mirror the issue-time logic on delete:
 ```ts
 deleteCookie(c, COOKIE_NAME, {
  path: '/', httpOnly: true,
  secure: process.env.NODE_ENV === 'production',
  sameSite: 'Lax',
 });
 ```
 ### BL-03: OIDC-link binding swallows `processOAuthCallback` failure and can bind on a stale/blank identity
 **File:** `apps/api/src/index.ts:57-101`
 **Issue:** In the `/callback` link path the code calls `processOAuthCallback(c)` then
 `getAuth(c)` and binds whatever `iss`/`sub` it finds to `linkUserId`. Two problems:
 (1) `iss`/`sub` fall back to `''` (`auth.iss ?? ''`, `auth.sub ?? ''`); if `getAuth` returns
 a partially-populated session, `linkOidcToUser(linkUserId, '', '')` will write
 `oidc_iss=''`/`oidc_sub=''` onto the user and **delete their local_credentials** — locking
 them out of both auth methods. (2) `linkUserId` comes from a JWT signed with
 `LOCAL_SESSION_SECRET`, but nothing verifies the *currently authenticated session* matches
 `linkUserId`; the signed-state CSRF defense assumes the state can only have been produced by
 `POST /api/me/link-oidc`, but the callback binds to `linkUserId` regardless of who completes
 the OIDC login. An attacker who can get a victim to complete an OIDC login while replaying a
 captured (still-valid, 10-min) link state binds the *attacker's* OIDC identity to the
 *victim's* account — account takeover.
 **Fix:** Reject the bind unless `iss` and `sub` are both non-empty, and cross-check that the
 OIDC identity being bound is the one the initiating user intended (e.g. require the
 post-callback session's subject to be confirmed by the user, or bind only when the
 initiating local session is still present and matches `linkUserId`). Never call
 `linkOidcToUser` with empty iss/sub.
 ### BL-04: `localAuthMiddleware` fabricates `oidcSub` collisions for local users
 **File:** `apps/api/src/auth/localAuthMiddleware.ts:88-94` and `apps/api/src/db/schema.ts:60-64`
 **Issue:** When populating context for a local user with null OIDC fields, the middleware
 substitutes `oidcIss: 'local'` and `oidcSub: String(row.id)`. This is only a context shape
 and is not persisted by the middleware — but `me.ts:resolveUserId` (the OIDC path) and
 `upsertUser` key identity on `iss+sub`, and the `users` table has
 `unique('uniq_oidc_identity').on(oidcIss, oidcSub)`. If any code path ever upserts using the
 context's `('local', String(id))` pair (e.g. a future call to `upsertUser` with these
 values), two local users would deterministically collide or a local user could shadow a real
 OIDC identity whose `(iss,sub)` happened to equal `('local','<n>')`. The fabricated values
 leak a synthetic identity namespace that overlaps the real one.
 **Fix:** Keep the context `oidcIss/oidcSub` as `null` for local users (widen the
 `ContextVariableMap` `user` type to allow null) rather than inventing `'local'`/`String(id)`
 sentinels that share a uniqueness domain with real OIDC identities.
 ## Warnings
 ### WR-01: `reset-admin.ts` interpolates the username into a log line and trusts `--password ''`
 **File:** `apps/api/scripts/reset-admin.ts:60-66, 123, 133`
 **Issue:** Two issues. (1) The arg parser treats any token starting with `--` as a new flag,
 so `--password --foo` yields `password=''`; combined with the dry-run branch the validation
 is loose. More importantly a password that legitimately begins with `--` (or is the empty
 string) is silently coerced to `''`. (2) The username is interpolated directly into
 `console.log(... username="${username}")`; while not an injection into SQL (queries are
 parameterized — good), logging the username is a minor info disclosure for a break-glass tool
 and inconsistent with the password-never-logged contract.
 **Fix:** Parse `--password=value` and `--password value` explicitly; do not infer empty
 strings from a following flag. Avoid echoing the username, or document it as acceptable.
 ### WR-02: `me.ts` builds the OIDC authorization URL with a hardcoded Authelia path
 **File:** `apps/api/src/routes/me.ts:331`
 **Issue:** `new URL(`${issuer}/api/oidc/authorization`)` hardcodes Authelia's authorization
 endpoint path. The project's stated design is to discover endpoints via
 `/.well-known/openid-configuration` (the whole reason `@hono/oidc-auth` is used). Any
 non-Authelia or differently-mounted provider will get a wrong URL. This is a latent
 correctness bug that compounds CR-01.
 **Fix:** Resolve the authorization endpoint from the discovery document rather than assuming
 `/api/oidc/authorization`.
 ### WR-03: `scryptSync` blocks the event loop on the login hot path
 **File:** `apps/api/src/auth/localCredentials.ts:42-53, 71-90` and `localAuth.ts:127-129`
 **Issue:** `verifyPassword` always runs `scryptSync` (N=16384) synchronously, including the
 dummy-hash branch on every failed/unknown login. The file comment justifies this for a
 2-person household, but combined with the per-IP rate limiter and the always-run dummy hash,
 a burst of unauthenticated `POST /local/login` requests can pin the single Node event loop
 (each scrypt is ~tens of ms of blocking CPU) and stall *all* other API traffic — a cheap
 unauthenticated DoS. The rate limiter does not protect this because the scrypt runs *before*
 the failure counter is consulted on the dummy path for new IPs.
 **Fix:** Use `promisify(scrypt)` (async) so hashing does not block the loop, as the comment
 itself suggests. This keeps the timing-defense property while preventing loop starvation.
 ### WR-04: `authMode` / OIDC-enabled detection diverges across three files
 **File:** `apps/api/src/routes/authMode.ts:33-49`, `apps/api/src/auth/middleware.ts:62-114`,
 `apps/api/src/routes/me.ts:323-328`
 **Issue:** Three independent notions of "is OIDC configured": `authMode` checks
 `OIDC_ISSUER` env OR `app_config.oidc_issuer`; the fallback middleware injects
 issuer/client-id/external-url from app_config; but `me.ts` link-oidc only builds a URL when
 `OIDC_ISSUER && OIDC_CLIENT_ID && OIDC_REDIRECT_URI` are all in **env** (it never consults
 app_config). So a wizard-configured-but-not-restarted instance reports `oidcEnabled:true`
 from `/api/auth/mode`, shows the "Link OIDC" button, but `link-oidc` returns
 `authorizationUrl:null` — inconsistent state surfaced to the user.
 **Fix:** Centralize the "OIDC configured" resolution (env-or-app_config) in one helper and
 use it in all three sites.
 ### WR-05: `noEchoHook` return value is ignored by `@hono/zod-validator` in one of two styles
 **File:** `apps/api/src/routes/localAuth.ts:39-43`, `apps/api/src/routes/admin.ts:74-78`,
 `apps/api/src/routes/me.ts:178-182`
 **Issue:** The hook signature is `(result, c)` and returns `c.json(...)` only on failure. This
 relies on zValidator short-circuiting when the hook returns a Response. That contract holds
 for current `@hono/zod-validator`, but the hook does not `return` anything on success and does
 not assert `result.success` narrows the type, so a future validator version that requires an
 explicit early-return-on-success, or that passes through when the hook returns `undefined`,
 would silently start echoing Zod errors (the exact T-19-14 leak this guards against). It is
 correct today but fragile and untested for the pass-through case.
 **Fix:** Add a focused test asserting that a malformed body never includes `received`/the
 submitted value for each hook site (localAuth has one; admin/me password routes should too),
 and pin the `@hono/zod-validator` version.
 ### WR-06: Rate-limit `lockedUntil` is refreshed on every blocked attempt, extending the window indefinitely
 **File:** `apps/api/src/routes/localAuth.ts:97-106, 133-137`
 **Issue:** On a 429 the code sets `attempt.lockedUntil = Date.now() + RATE_WINDOW_SECS*1000`
 again, so an attacker who keeps hitting the endpoint perpetually slides the cooldown forward —
 a legitimate user behind the same IP can never get back in even after pausing, because every
 attacker request re-arms the window. Coupled with CR-04 this makes the household-wide lock
 effectively permanent under sustained traffic.
 **Fix:** Do not extend `lockedUntil` on requests that are themselves rejected by the window;
 only set it when transitioning from below-threshold to at-threshold.
 ### WR-07: `parseInt` member/calendar id accepts trailing garbage
 **File:** `apps/api/src/routes/admin.ts:215-218, 307-311`
 **Issue:** `parseInt(c.req.param('id'), 10)` returns `12` for `"12abc"` and the `isNaN`
 guard passes. Not exploitable here (the value is used only in a parameterized `eq`), but it
 silently accepts malformed ids and could mask client bugs. The `/members/:id/password` and
 `/calendars/:id/shared` routes both use this pattern.
 **Fix:** Validate with `Number.isInteger(Number(raw))` or a Zod param schema so `"12abc"` is
 rejected with 400.
 ## Info
 ### IN-01: `localSession` `maxAge`/expiry parsing has no validation
 **File:** `apps/api/src/auth/localSession.ts:31`
 **Issue:** `Number(process.env.LOCAL_SESSION_EXPIRES ?? 86400)` yields `NaN` for a malformed
 value, producing a JWT with `exp = now + NaN` (→ `NaN`) and a cookie `maxAge: NaN`. Verify
 behavior is then "always expired" or "never expires" depending on the JWT lib's NaN handling.
 **Fix:** Coerce and validate: `const n = Number(env); SESSION_MAX_AGE = Number.isFinite(n) && n > 0 ? n : 86400;`
 ### IN-02: Duplicated inline scrypt implementation across three locations
 **File:** `apps/api/scripts/reset-admin.ts:45-51`, `.gitea/workflows/ci.yml:307-311`,
 `apps/api/src/auth/localCredentials.ts:42-53`
 **Issue:** The PHC scrypt hash is copy-pasted in the reset-admin script, the CI seed step,
 and the canonical module. If the parameters ever change (the file comment advertises
 parameter evolution as a feature), these three drift and produce incompatible hashes. The
 duplication is documented as necessary (cannot import compiled TS from a plain script), but
 there is no test asserting the three stay in lockstep.
 **Fix:** Add a test that imports `hashPassword` and asserts a known input round-trips against
 a hash produced by the inlined parameters, so a parameter change fails CI loudly.
 ### IN-03: `loginAttempts` map is unbounded (memory growth)
 **File:** `apps/api/src/routes/localAuth.ts:66`
 **Issue:** Entries are only removed on a *successful* login for that IP. Spoofed/rotated
 `X-Forwarded-For` values (see CR-04) accumulate map entries with no eviction, a slow memory
 leak. Out of strict v1 perf scope, noted because it is reachable by unauthenticated input.
 **Fix:** Add periodic eviction of entries whose `lockedUntil` is far in the past.
 ### IN-04: `me.ts` link-oidc nonce is generated but never persisted/verified
 **File:** `apps/api/src/routes/me.ts:312-320` and `apps/api/src/index.ts:60-74`
 **Issue:** The signed state carries a `nonce` "to prevent replay," but the `/callback`
 handler never records or checks the nonce — it only verifies the JWT signature and reads
 `linkUserId`. A captured state JWT is fully replayable within its 10-minute window (the
 signature stays valid), so the nonce provides no actual replay protection. This underlies
 the takeover concern in BL-03.
 **Fix:** Persist issued nonces (or a single-use jti) and reject a state whose nonce was
 already consumed, or shorten the window and bind the state to the initiating session cookie.

 # Phase 19: Code Review Report (Iteration-2 Re-Review)
 **Reviewed:** 2026-06-17
 **Depth:** deep
 **Files Reviewed:** 41
 **Status:** clean
 ## Summary
 This is the iteration-2 re-review confirming the fixer correctly applied all 15
 findings from the prior review (4 critical, 4 blocker, 7 warning, 4 info). I read
 every listed source file, traced the high-judgment fixes through their full call
 chains across module boundaries, ran `tsc --noEmit` on both `@familysync/api` and
 `@familysync/pwa` (both clean, exit 0), and confirmed the CI seed parameters and
 inlined scrypt copies all agree. The runtime test suite could not execute in this
 sandbox (global-setup requires a live MariaDB with root grants — `ER_ACCESS_DENIED`),
 so test verification is static: the relevant assertions were read directly and the
 production source typechecks against them.
 **Verdict: all 15 prior findings are correctly and completely resolved. No
 regressions, no re-occurrence at other call sites, and no new critical/blocker/warning
 issues.** Two low-severity Info observations are recorded below; neither blocks ship.
 ### Confirmation of high-judgment fixes (verified by tracing, not just diff)
 - **CR-01/02/03 (client↔server contracts):**
  - CR-01 shared-calendar: `admin.ts` `PUT /calendars/:id/shared` now does an
    existence check inside a transaction (404 on missing id), so a stale id can no
    longer silently clear the shared lane. Client `setSharedCalendar` agrees.
  - CR-02 create-member: client `fetchCreateMember` maps `password → initialPassword`
    (client.ts:199-204) and the server `createMemberSchema` requires `initialPassword`
    (admin.ts:140); 409 maps to the `'conflict'` sentinel the AdminPage `onError`
    expects (AdminPage.tsx:229). Server returns 409 on `ER_DUP_ENTRY` (admin.ts:202).
    Both ends agree; admin.test.ts Tests 1–2 cover the round-trip + 409 rollback.
  - CR-03 wrong-current-password: server returns **403** (`me.ts:267`), client checks
    403 **before** the 401 session-expiry branch (client.ts:166) and maps it to
    `'wrong-current'`, which `ChangePasswordSheet.onError` surfaces without dropping
    the session (SettingsSheet.tsx:569). me.test.ts Test 2 asserts 403 + update-not-called.
 - **CR-04 / WR-06 / IN-03 (login limiter):** the limiter key is the validated,
  trimmed username (localAuth.ts:138) — no `x-forwarded-for`/IP residue remains
  anywhere in `routes/localAuth.ts` or `src/auth/*` (grep clean). 423 lockout
  auto-expires after `LOCKOUT_TTL_MS` (15 min, localAuth.ts:149-155); admin reset
  calls `resetLoginAttempts(credRow.username)` for an instant unlock (admin.ts:262).
  WR-06: the 429 branch deliberately does **not** re-arm `lockedUntil`
  (localAuth.ts:164-169), so a rejected attempt can no longer slide the window
  forward; the window is only re-anchored by a genuine failure in the failure path.
  IN-03: `evictStaleLoginAttempts` only drops entries that are both window-expired
  and lockout-TTL-expired (localAuth.ts:113-121) — behaviourally identical to natural
  expiry, so eviction never weakens the brute-force defense. Tests 4, 5, 5b cover it.
 - **BL-01 (dev-bypass secret floor):** `devSessionCookieMiddleware` applies the same
  `>= 32` length floor before minting a real DEV_USER session JWT (devBypass.ts:144-151)
  and warns on the well-known placeholder. The CI placeholder
  `dev-secret-change-me-0000000000000000` is 36 chars, so it passes the floor and only
  triggers the warning — intended.
 - **BL-02 (logout cookie Secure match):** `clearLocalSessionCookie` now mirrors the
  issue-time `secure: NODE_ENV==='production'` (localSession.ts:114), so the
  delete-cookie is accepted over plain HTTP and the user is actually logged out on
  non-HTTPS deployments. `sameSite`/`path`/`httpOnly` also match issue-time.
 - **BL-03 (OIDC-link takeover guard):** `/callback` (index.ts:84-123) now enforces
  three gates before binding: (1) single-use nonce via `consumeLinkNonce`; (2) the
  initiating local session must still match `linkUserId`
  (`verifyLocalSessionCookie(c) === linkUserId`); (3) `iss`/`sub` from `getAuth` must
  be non-empty. `/callback` is registered outside `/api/*` so `localAuthMiddleware`
  does not run, but the `local-session` cookie (path `/`) is still present and read
  directly — the cross-check is effective. All three gates fail-closed to
  `/?error=oidc-link-conflict`. The preflight conflict check in `linkOidcToUser`
  (linkOidc.ts:65-74) remains the backstop.
 - **BL-04 (no fabricated identity sentinels):** `localAuthMiddleware` passes through
  the DB `oidcIss`/`oidcSub` as `?? null` (localAuthMiddleware.ts:91-97); `ContextUser`
  widens both to `string | null` (devBypass.ts:56-62). No `'local'`/`String(id)`
  sentinels are written, so a local user cannot collide in the `uniq_oidc_identity`
  domain. localAuthMiddleware.test.ts Test 1c pins null.
 - **WR-03 (async scrypt):** `hashPassword`/`verifyPassword` are async over the libuv
  threadpool (localCredentials.ts:33-45, 65, 101) at every call site — login
  (dummy-hash promise awaited, localAuth.ts:128/199), create-member (hash before the
  transaction, admin.ts:159), admin reset, and self-change. The always-run dummy-hash
  path preserves the timing-oracle defense (localAuth.ts:197-199). reset-admin.ts
  legitimately keeps `scryptSync` (standalone CLI, no event loop to starve).
 - **IN-04 (single-use nonce):** `linkNonceStore.ts` records the nonce at issue
  (me.ts:333) and `consumeLinkNonce` returns true exactly once per unexpired nonce,
  with opportunistic sweep keeping the map bounded; `/callback` consumes before binding.
 ### Cross-cutting checks
 - Inlined PHC scrypt parameters agree across all three copies: canonical module
  (N=16384,r=8,p=1,keylen=32), `reset-admin.ts`, and `.gitea/workflows/ci.yml`
  (seed step lines 309-310). localCredentials.test.ts Test 6 pins this round-trip.
 - `oidcConfig.ts` (`resolveOidcConfig` + `discoverAuthorizationEndpoint`) is the single
  env-OR-app_config source now shared by `/api/auth/mode`, the fallback middleware, and
  `me.ts` link-oidc, closing the WR-04 divergence where link-oidc could return
  `authorizationUrl:null` while `/mode` reported `oidcEnabled:true`.
 - `LOCAL_SESSION_EXPIRES` NaN-coercion guard (localSession.ts:35-38) and boot guards
  (`assertLocalSessionSecretSet` >= 32, exempt under bypass) are correct and wired
  first in the `isMainModule()` block (index.ts:262-265).
 - Migration `0003_warm_deathstrike.sql` matches the `localCredentials` Drizzle schema
  (unique on user_id and username, FK cascade, varchar(256) hash).
 ## Info
 ### IN-01: `fetchLinkOidc` declared return type is narrower than the cast it returns
 **File:** `apps/pwa/src/api/client.ts:250,261`
 **Issue:** The function signature declares `Promise<{ authorizationUrl: string | null }>`
 but the body returns `res.json() as Promise<{ signedState: string; authorizationUrl: string | null }>`.
 The widening cast is harmless (the only consumer, `SettingsSheet.tsx` `LinkOidcSheet`,
 reads `data.authorizationUrl` only and never `signedState`), and `tsc` is clean. It is a
 minor contract-doc inconsistency: the declared type drops a field the server actually
 sends. Not a defect — recorded only so the next editor does not "fix" the cast and
 accidentally start relying on the absent field.
 **Fix:** Align the declared return type with the cast for clarity:
 ```ts
 export async function fetchLinkOidc(): Promise<{ signedState: string; authorizationUrl: string | null }> {
 ```
 ### IN-02: 429 rate-limit branch short-circuits before the dummy-hash work
 **File:** `apps/api/src/routes/localAuth.ts:162-177`
 **Issue:** Once an identity is in the 429 window, the handler returns before the DB
 lookup and the always-run `verifyPassword`/dummy-hash. This is a deliberate and correct
 DoS/throughput tradeoff (a rate-limited identity should not pay scrypt cost), and it does
 NOT leak username existence because the 429 path is reached identically for valid and
 invalid usernames (the limiter is keyed on the submitted username regardless of whether a
 credential row exists). The timing-oracle defense is only required on the *credential-check*
 path, which still always runs the dummy hash. Recorded for completeness; no change needed.
 **Fix:** None required. If a future reviewer wants strict constant-time even under
 rate-limiting, the dummy-hash could be awaited before the 429 return — but that would
 re-introduce the exact event-loop-starvation cost WR-03 removed, so leaving it as-is is
 the right call.

 ## Deviation Note — T-19-11 (rate-limit key)
 The register declares "per-IP rate-limit". The implementation (`localAuth.ts`, CR-04) keys the
 limiter on the **submitted username**, not the client IP. This is a deliberate, documented
 deviation: in this Pangolin-tunnel deployment all household traffic shares one X-Forwarded-For
 first hop (so IP-keying let one actor lock out every member) and X-Forwarded-For is spoofable.
 The declared security property — brute-force resistance via 5→429 and 10→423 with admin-reset
 recovery and a self-healing TTL — is fully present. Treated as CLOSED. The register wording is
 stale relative to the shipped (stronger-for-this-topology) mechanism.
 ---
 ## Accepted Risks Log
 | Threat ID | Risk | Rationale |
 |-----------|------|-----------|
 | T-19-22 | Client `isAdmin` / `hasLocalCredential` flags are UX-only and trivially editable in the browser. | Accepted: these flags only gate PWA nav/affordances. The real authorization boundary is server-side `requireAdmin` on every `/api/admin/*` request (`admin.ts:47`) and session-derived `resolveUserId` on `/api/me/*`. Client gating is never the security boundary. Documented prior decision. |
 | T-19-16 | "Authelia" provider name could leak infrastructure detail in UI/comments. | Low-severity hygiene (accept→mitigate). D-06 applied across Phase-19-touched surfaces; remaining occurrences are in the out-of-scope Phase 12 `SetupPage.tsx` wizard and in source comments, not on the local-auth surfaces this phase introduced. |
 ---
 ## Unregistered Flags
 The two `## Threat Flags` entries in `19-04-SUMMARY.md`
 (`threat_flag: credential-in-controlled-state` for `LoginPage.tsx` and `SettingsSheet.tsx`)
 both map to existing register threats **T-19-18** (password in client storage). Informational
 only — no unregistered attack surface. No WARNING raised.
 ---
 ## Out-of-Scope Observation (non-blocking, not a Phase 19 gap)
 `apps/pwa/src/routes/SetupPage.tsx` (lines 379, 498, 627, 645, 695) renders the literal string
 "Authelia" in the first-run setup wizard. This file was **not** modified in Phase 19
 (`git diff main...HEAD` = no changes) — it is the pre-existing Phase 12 wizard, outside the
 T-19-21 mitigation scope ("any PWA source touched by this plan"). It does not affect the local-auth
 login/admin/settings surfaces. Flagged here for a future D-06 sweep of the setup wizard; it is
 **not** an open Phase 19 threat.

 ## Live UAT Session (resumed 2026-06-17, post code-review-fix)
 **Stack configured for local-auth / no-OIDC mode** (Phase 19's canonical deployment):
 - API rebuilt from the phase-19 branch (all 18 code-review fixes live; verified `initialPassword` + 403 present in running `dist`).
 - `DEV_AUTH_BYPASS=false` and `OIDC_ISSUER=""` via throwaway `docker-compose.uat.yml` override
  (tracked files untouched; restore the normal bypass stack after UAT).
 - Seeded local admin: **username `uatadmin` / password `UATtest1234!`** (user id 2, is_admin=1).
 - PWA on host Vite at **http://localhost:5173**.
 **Automated API smoke (pre-checks):**
 - ✅ `POST /api/auth/local/login` (uatadmin) → 200 + `local-session` cookie.
 - ✅ Wrong password → 401 `{"error":"Invalid credentials"}` (generic, no field blame).
 - ✅ Authenticated `GET /api/me` → `{id:2, isAdmin:true, hasLocalCredential:true}`.
 - ⚠️ Unauth `GET /api/me` → **500 `Invalid session`** (not 401) in no-OIDC mode: the OIDC guard
  is mounted whenever bypass is off and errors trying to redirect with a blank issuer. **Cosmetic**
  — PWA gates on `meQuery.isError && localEnabled` (App.tsx:213) so it still redirects to `/login`.
  Candidate follow-up: short-circuit the OIDC guard to a clean 401 when no issuer is configured.
 **Note on Item 1 OIDC button:** the "OIDC button appears when oidcEnabled" sub-check can't be
 exercised on this box (no reachable Authelia → blanked). Covered at unit/e2e level. This session
 verifies the no-OIDC local-auth surface, which is the phase's primary deliverable.
 # Phase 19: Local Auth (No-OIDC Mode) — User Acceptance Tests
 All automated verification passed (API 446/446, PWA 266/266, e2e desktop 42 passed
 / 3 skipped, typecheck clean; VERIFICATION.md status: passed, 21/21 must-haves).
 The single blocker found during verification (admin reset-password URL mismatch) was
 fixed and confirmed live (commit `53da4be`).
 The items below are the remaining **human / live-stack** checks that cannot be driven
 from the dev `DEV_AUTH_BYPASS` harness or a headless box. They do not block automated
 goal achievement but should be confirmed before shipping.
 ## UAT Items
 ### 1. Login page visual + flow (real, non-bypass stack)
 - **Test:** Run the stack with OIDC/Authelia configured and `DEV_AUTH_BYPASS` **off**.
  Visit the app unauthenticated → confirm redirect to `/login`. Verify the brand slot
  ("FS" mark, "FamilySync", "Family calendar & lists"), the form (username auto-focus,
  password show/hide), wrong-creds single error ("Incorrect username or password."),
  correct-creds navigation into the app, and the OIDC button only when `oidcEnabled`.
 - **Expected:** All surfaces per 19-UI-SPEC; no "Authelia" text anywhere; error copy
  never blames a specific field.
 - **Why human:** The unauth login-gate redirect is unreachable under the bypass-only
  harness (covered at unit level in `App.test.tsx`); the full visual flow needs a real
  browser against a non-bypass deployment. (Desktop/Chromium portions are already e2e-
  covered via `login.spec.ts`.)
 - **result: pass** (2026-06-17, live no-OIDC stack, operator-confirmed — all steps:
  redirect to /login, brand slot, username autofocus, password show/hide, generic
  wrong-creds error, successful login into the app). Setup-gate precedence confirmed:
  `setupComplete===true` so /login is reachable (App.tsx checks `/setup` redirect first).
 ### 2. Admin Reset-password sheet (live, end-to-end)
 - **Test:** As an admin, open Admin → Local Accounts → Reset password for a member;
  submit a new password; confirm the member can then log in with it.
 - **Expected:** `POST /api/admin/members/:id/password` returns 200; new password works.
 - **Why human:** Needs a live stack with an admin session and a real local member.
  (URL fix already verified: route reachable, 404 eliminated.)
 - **result: pass (functional) — with UX gap.** Operator created `testmember` + reset its
  password via the admin UI. Verified at DB/login level: member exists (user 3, non-admin);
  login with the **reset** pw (`MemberPass456!`) → 200; login with the **original**
  (`MemberPass123!`) → 401. So **CR-02 create-member + reset both work and persist.**
  BUT neither action showed a success confirmation (see Finding F-01).
 ### 3. Settings Change-password sheet (live, local user)
 - **Test:** As a local user, Settings → Account → Change password; verify wrong current
  password shows "Current password is incorrect.", correct current updates, and the new
  password works on next login.
 - **Expected:** Current-password verification enforced; update succeeds; re-login works.
 - **Why human:** Needs a live stack with a local-user session.
 - **result: pass** (2026-06-17, verified functionally via API on the live no-OIDC stack as
  `testmember`). CR-03 confirmed: wrong current password → **403 (not 401)** and the session
  stays valid (`/me`→200, no force-logout); correct current → 200; new password logs in (200),
  old password rejected (401).
 ### 4. Rate-limit / lockout test flakiness (harden)
 - **Test:** Run `apps/api/tests/routes/localAuth.test.ts` Test 5 (10 failures → 423)
  ~10 times; characterize the intermittent failure the orchestrator observed (1 failure
  across 3 runs, then stable).
 - **Expected:** Stable pass; if timing-dependent, harden the in-memory rate-limit test
  (e.g. fake timers / deterministic clock).
 - **Why human:** Timing-dependent in-memory test; needs repeated runs to characterize.
 - **result: resolved-by-fix.** The code-review fix (CR-04/WR-06/IN-03) rewrote the limiter and
  made the lockout test **deterministic** — it back-dates `lockedAt` instead of using wall-clock
  timers (`localAuth.test.ts:280`), structurally removing the timing flakiness. The fixer ran the
  full API suite **452/452** (incl. Test 5/5b). Couldn't be re-run in this session's shell (no
  test-DB root creds — `ER_ACCESS_DENIED`); confirm via CI or `set -a; . ./.env; set +a;
  DB_HOST=127.0.0.1 pnpm --filter @familysync/api test`.
 ### 5. CI harness green + D-15 image boundary (push, outward-facing)
 - **Test:** Push the branch and open the PR so Gitea CI runs. Confirm the `harness` job
  (iphone + pixel + desktop, incl. `login.spec.ts`) is green, the `api` job is green,
  and the published-image hygiene checks (no `apps/api/scripts/` or `apps/pwa/e2e/` in
  the prod image) pass.
 - **Expected:** CI all green; no dev artifact in the shipped image (D-14/D-15).
 - **Why human:** Pushing to the remote / triggering CI is an outward-facing action the
  operator owns. (Plan 19-05's blocking checkpoint.)
 - **result: deferred to `/gsd-ship`** (operator decision 2026-06-17). The push/PR/CI run +
  image-hygiene gate is owned by the ship workflow, not this UAT session.
 ## Live Session Findings (2026-06-17)
 Surfaced by the operator during Test 2. **Operator decision (2026-06-17): route ALL four UI
 findings — including the logout button — to Phase 17 (UI Optimization & Polish), which has not yet
 kicked off. None block Phase 19**, whose auth machinery is functionally complete and verified.
 All four added to `17-CONTEXT.md` (Phase-17 branch):
 - **F-02 — No logout button in the UI (functional-UI).** Logout is fully plumbed — endpoint
  `POST/GET /api/auth/local/logout` returns 200 and clears the cookie (BL-02 verified live), and
  `fetchLocalLogout()` exists in `apps/pwa/src/api/client.ts:127` — but **no component calls it**
  (grep of `apps/pwa/src` finds zero logout buttons/handlers). Phase 17 wires a logout control to
  the existing client function (no backend work). Per operator: a UI concern, not a Phase-19 blocker.
 - **F-01 — Admin create/reset give no success feedback.** Both succeed (verified at DB/login level)
  but show no success toast/confirmation. Add success feedback to the admin local-account flows.
 - **F-03 — Dialogs/popups render at bottom-center instead of properly centered (cosmetic).** Fits
  Phase 17's fixed-chrome/sheet-positioning sweep.
 - **F-04 — Admin UI navigation is clunky and needs a rework.** UX-polish item for Phase 17.
 **Status:** Phase 19 UAT **complete (functional)** — Tests 1–3 pass (live), Test 4 resolved-by-fix,
 Test 5 deferred to `/gsd-ship`. No Phase-19 blockers. F-01–F-04 carried to Phase 17.

 # Phase 19 — UI Design Contract: Local Auth (No-OIDC Mode)
 > Visual and interaction contract for the local login screen, login-method chooser,
 > and admin-surface additions for local account management.
 > Generated by gsd-ui-researcher. Verified by gsd-ui-checker.

 ## Context & Audience
 This phase introduces the **first real login UI** in the FamilySync PWA. Today the PWA boots
 straight into the authed app (OIDC redirect) or via dev-bypass — there is no login form. Phase 19
 builds:
 1. A **local login screen** (username + password) — full-viewport, pre-auth, the first surface an
   unauthenticated user sees. This is the highest-value branding surface in the app.
 2. A **login-method chooser** rendered when OIDC is also configured (D-02) — local form OR
   "Login with OIDC" (generic, never says "Authelia" — D-06).
 3. Admin-surface additions (in-app shell `/admin` route, extending Phase 10): local member
   creation + initial password; self password-change; admin password-reset; per-user
   "Link OIDC identity" action.
 The login screen is **end-user-facing**, not operator-facing. The non-technical Apple household
 member is the primary user — UX must be slick and low-friction (CLAUDE.md hard constraint).
 The login screen is a **standalone full-page route**, most closely analogous to the Phase 12
 setup wizard (`/setup`). It renders none of the AppNav / BottomTabBar / SetupBanner chrome.
 All design tokens are inherited from `apps/pwa/src/styles/tokens.css`. No new tokens are
 introduced.
 ---
 ## Design System
 | Property | Value |
 |----------|-------|
 | Tool | none (existing CSS custom properties) |
 | Preset | not applicable |
 | Component library | none (hand-rolled inline `React.CSSProperties`, project convention) |
 | Icon library | lucide-react (already installed — `Lock`, `User`, `Eye`, `EyeOff`, `Loader2`, `AlertCircle`, `LogIn`, `ShieldCheck`) |
 | Font | system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', sans-serif (var(--font-family-base)) |
 Source: `apps/pwa/src/styles/tokens.css` — pre-populated from existing codebase scan.
 Pattern baseline: `apps/pwa/src/routes/SetupPage.tsx` (full-viewport standalone page),
 `apps/pwa/src/routes/AdminPage.tsx` (admin-surface additions).
 ---
 ## Spacing Scale
 Uses the existing 4px-based scale. No new tokens.
 | Token | Value | Usage in this phase |
 |-------|-------|---------------------|
 | --space-1 | 4px | Icon gaps, label-to-input gap, helper-text margin-top |
 | --space-2 | 8px | Compact element spacing, password show/hide button gap, form field gap within a group |
 | --space-3 | 12px | Input padding (vertical), row gaps |
 | --space-4 | 16px | Between form fields, button horizontal padding, card horizontal padding |
 | --space-6 | 24px | Card padding, section gap, brand slot bottom margin |
 | --space-8 | 32px | Between the brand slot and the login card, between major sections |
 | --space-12 | 48px | Page top/bottom padding (matches SetupPage pattern) |
 Exceptions:
 - Login card max-width: 400px (narrower than wizard 540px; a two-field login needs less width).
 - All interactive elements: `minHeight: 44px; minWidth: 44px` (WCAG 2.5.5 Touch Target).
 - Password show/hide toggle: 44px tap target embedded inside the input row (right-side icon button).
 - Brand logo slot: reserved 48px height (aspect-ratio box 1:1); see Brand Slot section.
 ---
 ## Typography
 All values from `tokens.css`. No new sizes or weights.
 | Role | Size | Weight | Line Height | Variable |
 |------|------|--------|-------------|----------|
 | Body | 15px | 400 | 1.5 | var(--text-body-size) / var(--text-body-weight) / var(--text-body-line-height) |
 | Label | 13px | 400 | 1.4 | var(--text-label-size) / var(--text-label-weight) / var(--text-label-line-height) |
 | Heading | 18px | 600 | 1.25 | var(--text-heading-size) / var(--text-heading-weight) / var(--text-heading-line-height) |
 | Display | 24px | 600 | 1.2 | var(--text-display-size) / var(--text-display-weight) / var(--text-display-line-height) |
 Usage in this phase:
 - App name "FamilySync" in brand slot: Display (24px/600/1.2) — `var(--color-text-primary)`
 - App tagline "Family calendar & lists" in brand slot: Body (15px/400/1.5) — `var(--color-text-secondary)`
 - Login card heading ("Sign in"): Heading (18px/600/1.25) — `var(--color-text-primary)`
 - Field labels, helper text, divider label ("or"): Label (13px/400/1.4)
 - Field labels use weight 600, helper text uses weight 400
 - Section labels in admin additions ("LOCAL ACCOUNTS", "OIDC LINK"):
  13px/600/uppercase/0.06em letter-spacing (AdminPage `sectionLabelStyle` pattern)
 - Error messages: Body (15px/400/1.5) — `var(--color-destructive)`
 - Primary CTA label: Label (13px/600)
 ---
 ## Color
 All values from `tokens.css`. No new hex values.
 | Role | Value | Variable | Usage |
 |------|-------|----------|-------|
 | Dominant (60%) | #ffffff | var(--color-surface) | Page background, card background, input background |
 | Secondary (30%) | #f7f7f8 | var(--color-surface-dim) | Divider area between form methods, info banners, rate-limit notice background |
 | Accent (10%) | #4a90d9 | var(--color-member-0) | Primary CTA button ("Sign in"), spinner, focus ring, "Login with OIDC" button border |
 | Destructive | #dc2626 | var(--color-destructive) | Error message text, error-state input border, lockout notice, rate-limit warning |
 Accent reserved for:
 - "Sign in" button (filled background)
 - "Login with OIDC" button (outlined, `1px solid var(--color-member-0)`, accent text)
 - `Loader2` spinner during login submit
 - Focus ring on all inputs and buttons (`var(--color-focus-ring)`, 2px outline, 2px offset)
 - Text links (e.g., "Forgot password? Ask your admin.")
 Additional semantic colors (not new — already in tokens.css):
 - `var(--color-border)` #e2e4e9 — card border, input border (default), divider line
 - `var(--color-border-subtle)` #eceef2 — section dividers in admin additions
 - `var(--color-text-primary)` #111318 — headings, field values, app name
 - `var(--color-text-secondary)` #6b7280 — descriptions, helper text, tagline, divider label
 - `var(--color-text-muted)` #9ca3af — placeholder text, inactive admin rows
 - `var(--color-overlay)` rgba(0,0,0,0.32) — modal backdrop for confirmation dialogs

 ## Brand Slot — Phase 17 Readiness
 The login screen is the **highest-value branding surface** in the app — full-viewport,
 unauthenticated, the first thing any user sees. A reserved brand slot sits above the login
 card and is designed as a **theming/asset seam**: Phase 19 ships a minimal shippable
 placeholder; Phase 17 drops in real assets without restructuring the layout.
 ### Brand slot structure (Phase 19 ships this)
 ```
 [brand-slot]
  [--brand-logo placeholder] — 48×48px box, aspect-ratio 1/1, reserved intrinsic dimensions
                               Placeholder: a 48px circle, background var(--color-member-0),
                               initials "FS" in white Display (24px/600).
                               No broken image ref. No layout shift when replaced.
  [--brand-app-name]         — "FamilySync" text (Display 24px/600, var(--color-text-primary))
                               Rendered from a CSS custom property / named slot; not hardcoded.
  [--brand-tagline]          — "Family calendar & lists" (Body 15px/400, var(--color-text-secondary))
 ```
 Layout:
 - Centered column, `textAlign: center`
 - Logo mark: `width: 48px; height: 48px; borderRadius: 50%; margin: 0 auto var(--space-2)`
 - App name: `marginTop: var(--space-2); marginBottom: var(--space-1)`
 - Tagline: `marginBottom: var(--space-8)` (32px gap before the login card)
 ### Asset seam tokens
 Define in `tokens.css` (Phase 19 sets placeholder defaults; Phase 17 overrides):
 ```css
 :root {
  /* Phase 17 replaces these values — never the component structure */
  --brand-logo-bg: var(--color-member-0);       /* placeholder circle background */
  --brand-logo-text: #ffffff;                    /* placeholder initials color */
  --brand-logo-size: 48px;                       /* reserved slot height; keep 1:1 aspect */
  --brand-logo-border-radius: 50%;               /* circle for initials; Phase 17 may change */
  --brand-app-name: 'FamilySync';                /* not used as CSS content — drives doc only */
 }
 ```
 The logo slot renders via a React component `<BrandSlot />` in the login page — not inline JSX.
 This isolates the seam: Phase 17 replaces `<BrandSlot>` internals (swap placeholder div for
 `<img src="...">`) without touching `<LoginPage>` layout.
 ### Phase 17 readiness subsection
 **Phase 17 contract — what Phase 17 must honor:**
 | Slot | Asset Phase 17 provides | Constraints Phase 17 must respect |
 |------|-------------------------|-----------------------------------|
 | Logo mark | SVG or PNG, favicon-derived | Must fit in 48×48px box at 1x; provide 2x/3x for retina. `alt=""` (decorative — app name already in text) |
 | App name text | Same string "FamilySync" or updated display name | Rendered as text, not image — screen readers read it |
 | Tagline | Optional; may be removed | If removed, set `--brand-tagline-display: none` — no layout reflow |
 | Background hero | Optional — if added, must go behind the entire page, not just the brand slot | `var(--brand-bg): none` default; Phase 17 sets to a CSS gradient or subtle image |
 | Aspect-ratio box | Phase 17 MUST keep the 48px height reserve | Prevents layout shift; use `aspect-ratio: 1/1; width: var(--brand-logo-size)` |
 Phase 17 asset swap is: update `<BrandSlot>` internals (image src) + set CSS custom property
 values. No changes to `<LoginPage>` layout, spacing, or card structure are permitted by this
 contract.

 ## Surface Architecture
 ### Surface 1 — Login Page Shell (`/login`)
 A standalone full-page route. No AppNav, no BottomTabBar, no SetupBanner, no
 PermissionDeniedBanner at any breakpoint.
 - Background: `var(--color-surface)` (#ffffff)
 - Layout: `minHeight: 100dvh; display: flex; flexDirection: column; alignItems: center; justifyContent: flex-start`
 - Content column: `maxWidth: 400px; width: 100%; margin: 0 auto; padding: var(--space-12) var(--space-6)`
 Routing gate:
 1. On app load, `GET /api/auth/mode` (pre-auth endpoint — no session required) returns
   `{ localEnabled: true, oidcEnabled: boolean }`.
 2. If the user already has a valid session (local JWT cookie or OIDC session), they are
   redirected to `/calendar` before the login page renders.
 3. The `/login` route renders the `<LoginPage>` (full-viewport, no shell).
 4. After successful login, navigate to `/` (which redirects to `/calendar`).
 ### Surface 2 — Brand Slot
 Sits at the top of the content column, above the login card. Detailed in "Brand Slot" section.
 Not inside the login card — floats above it in the flow.
 ### Surface 3 — Login Card
 The primary login interaction area.
 - Background: `var(--color-surface)` (#ffffff)
 - Border: `1px solid var(--color-border)` (#e2e4e9)
 - Border-radius: 8px
 - Padding: `var(--space-6)` (24px) all sides
 - Box-shadow: `0 1px 4px rgba(0,0,0,0.06)` (matches SetupPage cardStyle)
 - Card heading "Sign in": Heading (18px/600/1.25), `var(--color-text-primary)`,
  `marginBottom: var(--space-6)` (24px)
 ### Surface 4 — Username Field
 - Label: "Username" — 13px/600, `var(--color-text-primary)`, `marginBottom: var(--space-1)` (4px)
 - Input: `type="text"`, `autoComplete="username"`, `id="login-username"`
 - Style: full-width, `padding: var(--space-3) var(--space-4)`, `border: 1px solid var(--color-border)`,
  `borderRadius: var(--space-1)`, 15px/400, `var(--color-text-primary)`, `background: var(--color-surface)`
 - Error state border: `1px solid var(--color-destructive)`
 - `aria-describedby="login-error"` when error state is active
 - `spellCheck={false}`, `autoCapitalize="none"`, `autoCorrect="off"`
 ### Surface 5 — Password Field with Show/Hide Toggle
 - Label: "Password" — 13px/600, `var(--color-text-primary)`, `marginBottom: var(--space-1)` (4px)
 - Input wrapper: `position: relative`
 - Input: `type="password"` (toggled to `"text"` by show/hide button), `autoComplete="current-password"`,
  `id="login-password"`, `paddingRight: 44px` (space for toggle)
 - Error state border: `1px solid var(--color-destructive)`
 - Show/hide toggle button: `position: absolute; right: 0; top: 0; height: 100%; minWidth: 44px;
  background: none; border: none; cursor: pointer; color: var(--color-text-muted)` —
  renders lucide `Eye` (show) or `EyeOff` (hide), 16px, `aria-label="Show password"` /
  `"Hide password"`, `aria-pressed` reflects current state
 - Field container `marginBottom: var(--space-4)` (16px)
 ### Surface 6 — Form Error / Lockout Banner
 Shown below the password field, above the submit button. Uses `role="status"` + `aria-live="polite"`.
 **Error states in order of severity:**
 1. **Invalid credentials** (incorrect username or password):
   - Icon: `AlertCircle` (16px, `var(--color-destructive)`) inline
   - Copy: "Incorrect username or password." — Body (15px/400), `var(--color-destructive)`
   - Both fields remain editable; no field is specifically blamed (timing-safe: do not indicate
     which field is wrong)
   - Input borders: both switch to `var(--color-destructive)`
 2. **Rate limit** (too many attempts, not yet locked):
   - Background: `var(--color-surface-dim)` pill/banner, `border-radius: var(--space-1)`,
     `padding: var(--space-3) var(--space-4)`
   - Icon: `AlertCircle` (16px, `var(--color-destructive)`) inline
   - Copy: "Too many attempts. Please wait a moment and try again." — 13px/400,
     `var(--color-destructive)`
   - Submit button: disabled during rate-limit window
 3. **Account locked** (persistent lockout — household scale break-glass is CLI only, D-13):
   - Same banner style as rate-limit
   - Copy: "This account is temporarily locked. Contact your admin to reset access."
   - Submit button: disabled
 4. **Generic server error** (5xx / network):
   - Copy: "Something went wrong. Please try again." — Body (15px/400), `var(--color-destructive)`
   - Submit button: re-enabled after error
 ### Surface 7 — Primary Submit Button ("Sign in")
 - Filled: `background: var(--color-member-0)`, `color: #ffffff`
 - Width: 100% (full-width login button — D-04 low-friction for non-technical user)
 - Label: 13px/600, `fontFamily: var(--font-family-base)`
 - `minHeight: 44px`, `borderRadius: var(--space-1)` (4px), `border: none`
 - `transition: background 0.15s ease`
 - Disabled state: `background: var(--color-border)`, `cursor: default` (during submission or lockout)
 - Loading state: `Loader2` icon (16px, #ffffff, `animation: spin 1s linear infinite`) inline before
  label text; label changes to "Signing in…"
 - Enabled only when both username and password fields are non-empty
 ### Surface 8 — Method Divider (OIDC mode only)
 Rendered between the local login card and the OIDC button when `oidcEnabled === true` from
 `/api/auth/mode`. Not rendered when OIDC is not configured.
 - A horizontal rule with centered label "or":
  - `display: flex; alignItems: center; gap: var(--space-3); marginTop: var(--space-4); marginBottom: var(--space-4)`
  - Left/right lines: `flex: 1; height: 1px; background: var(--color-border)`
  - "or" label: 13px/400, `var(--color-text-secondary)`, `flexShrink: 0`
 ### Surface 9 — OIDC Login Button (OIDC mode only)
 Rendered below the method divider when `oidcEnabled === true`. Not rendered when OIDC is not
 configured. This is NOT inside the login card — it sits below the card, after the divider.
 - Outlined style: `background: transparent; border: 1px solid var(--color-member-0); color: var(--color-member-0)`
 - Width: 100% (matches Surface 7 width)
 - Label: "Login with OIDC" — 13px/600 (never says "Authelia" — D-06 BYO-Auth principle)
 - `minHeight: 44px`, `borderRadius: var(--space-1)`, `cursor: pointer`
 - On click: initiates the OIDC authorization-code flow (same as today's redirect)
 - `lucide ShieldCheck` (16px) inline before label text — represents "your SSO provider"
 - No loading state needed (redirect is instant)
 ### Surface 10 — Forgot Password Helper
 Below Surface 7 (sign-in button), inside the login card.
 - A single-line text: "Forgot your password? Ask your admin." — 13px/400,
  `var(--color-text-secondary)`, `textAlign: center; marginTop: var(--space-4)`
 - No link — password reset is admin-only (D-11), no self-service email reset (D-11, email
  out of project scope). The text is informational only; not interactive.
 - This copy is non-alarming for the non-technical user: frames it as a quick admin action,
  not a problem.
 ### Surface 11 — Admin Additions: Local Accounts Section
 Extends the existing `/admin` route (AdminPage.tsx), below the "MEMBERS" section and "SHARED
 CALENDAR" section. New section labeled "LOCAL ACCOUNTS" (section-label style: 13px/600/uppercase/
 0.06em letter-spacing, `var(--color-text-muted)`).
 **Sub-surface 11A — Create Member / Set Initial Password**
 A card/form within the LOCAL ACCOUNTS section:
 - Heading (inline, not a card): "Add member" — Body (15px/600/`var(--color-text-primary)`)
 - Fields (same input style as CredentialSheet):
  - Display name — `type="text"`, label "Display name"
  - Username — `type="text"`, label "Username", `autoComplete="off"`, `spellCheck={false}`, `autoCapitalize="none"`
  - Initial password — `type="password"`, label "Initial password", `autoComplete="new-password"`
  - Confirm password — `type="password"`, label "Confirm password", `autoComplete="new-password"`
 - Field error: inline below the specific field, 13px/400, `var(--color-destructive)`, same style as
  CredentialSheet validation failure
 - Submit: "Add member" — filled accent button (same style as admin Save Credential button),
  `minHeight: 44px`, right-aligned in action row. Disabled when any required field is empty or
  passwords do not match.
 - Success: form clears; member appears in the MEMBERS section above.
 - Error copy variants:
  - Username already taken: "That username is already in use. Choose a different one."
  - Passwords do not match: "Passwords do not match."
  - Weak password (if enforced): "Password is too short. Use at least 8 characters."
 **Sub-surface 11B — Admin Password Reset (per-member)**
 Accessible from each member row in the MEMBERS section via a new "Reset password" action button
 (alongside existing "Rotate credential"/"Add credential" buttons — shown only for members who have
 a local credential row).
 Opens a bottom sheet (mobile) / centered modal (desktop), identical pattern to CredentialSheet
 (role="dialog", aria-modal, Escape closes, focus returns to trigger):
 - Heading: "Reset password" — 18px/600
 - Member subtitle: "{DisplayName}" — 15px/400, `var(--color-text-secondary)`
 - Fields:
  - New password — `type="password"`, `autoComplete="new-password"`, label "New password"
  - Confirm new password — `type="password"`, `autoComplete="new-password"`, label "Confirm new password"
 - No current-password field — admin reset does not require knowing the old password
 - Action row (right-aligned, gap `var(--space-3)`):
  - Cancel: ghost button (same ghostBtnStyle as CredentialSheet)
  - "Reset password": filled accent button, disabled while fields empty or mismatch
 - Success: sheet closes; no toast (the action is silent — admin-only, not user-visible)
 - Error: inline below confirm field in `var(--color-destructive)`, 13px/400
 ### Surface 12 — Self Password-Change (member self-service)
 Accessible from the SettingsSheet (existing Settings bottom sheet the user opens from the avatar
 button). A new "Change password" row in SettingsSheet, shown only when the current user has a
 local credential (`hasLocalCredential: true` from `/api/me`). Tapping opens a bottom sheet
 (same pattern as CredentialSheet):
 - Heading: "Change password" — 18px/600
 - Fields:
  - Current password — `type="password"`, `autoComplete="current-password"`, label "Current password"
  - New password — `type="password"`, `autoComplete="new-password"`, label "New password"
  - Confirm new password — `type="password"`, `autoComplete="new-password"`, label "Confirm"
 - Action row:
  - Cancel: ghost button
  - "Change password": filled accent, disabled while any field empty or new/confirm mismatch
 - Success: sheet closes; no toast (self-service action is low-stakes confirmation)
 - Error variants:
  - Wrong current password: "Current password is incorrect."
  - Passwords do not match: "Passwords do not match."
  - Generic error: "Something went wrong. Please try again."
 - `aria-describedby` on each field pointing to the specific inline error
 ### Surface 13 — Link OIDC Identity (per-user action)
 Shown in SettingsSheet for the currently authenticated user, only when:
 - The user has a local credential (is a local user, not already OIDC-only)
 - OIDC is enabled (`oidcEnabled === true` from app state)
 Entry point: a "Link OIDC identity" row in SettingsSheet, below "Change password" (if shown).
 Tapping opens a **confirmation bottom sheet** (not a form — the actual linking happens via OIDC
 redirect, so the sheet just explains consequences):
 - Heading: "Link OIDC identity" — 18px/600
 - Body (15px/400, `var(--color-text-secondary)`, `lineHeight: 1.5`):
  "After linking, you'll sign in with your OIDC provider instead of a username and password.
  Your local password will be removed."
 - This is informational, not alarming: frame as an upgrade, not a removal.
 - Do NOT use the word "delete" or "remove" in the primary copy.
 - A secondary note in `var(--color-text-muted)` 13px/400:
  "This can't be undone from the app. Contact your admin if you need to revert."
 - Action row:
  - "Cancel" ghost button
  - "Continue with OIDC" filled accent button (D-06: never "Continue with Authelia")
 - On "Continue with OIDC": sheet closes; OIDC authorization-code flow initiates.
  On callback, backend binds `iss+sub` to the user and deletes the `local_credentials` row (D-12).
  User is then redirected to `/calendar` as a now-OIDC-only user.
 - If the OIDC `iss+sub` already belongs to another user: the callback returns a 409 error.
  The PWA shows a generic error page: "This OIDC identity is already linked to another account.
  Please contact your admin." (not shown in the sheet — occurs post-redirect)
 ---
 ## Routing & App-Level Gate
 1. On app load, `GET /api/auth/mode` is fetched pre-auth (before OIDC middleware, no session
   required). Returns: `{ localEnabled: true, oidcEnabled: boolean }`.
 2. If the user has a valid session (any method): skip `/login`, proceed to normal app routes.
 3. If no valid session AND `localEnabled === true`: render `/login` (Surface 1).
 4. If no valid session AND `localEnabled === false` AND `oidcEnabled === true`: initiate OIDC
   redirect directly (no login page shown — OIDC-only mode, today's behavior).
 5. The `/login` route does NOT render inside the normal App shell — no AppNav, no BottomTabBar.
 The existing `AuthSplash` component (spinner + "Signing you in") continues to be shown during
 any auth-state loading before the login page is reached.
 The Phase 12 setup gate (`/api/setup/status`) takes priority: if `setupComplete === false`, the
 app redirects to `/setup` before reaching the login gate.
 ---
 ## Interaction Contract
 ### Login form state machine
 ```
 fields empty                → Submit disabled
 username OR password empty  → Submit disabled
 both fields non-empty       → Submit enabled
 submit tapped               → loading state (Loader2 spinner, "Signing in…", submit disabled)
  success                   → navigate to /calendar (cookie set by API)
  401 invalid credentials   → error state (Surface 6, variant 1); fields remain editable; reset loading
  429 rate limit            → error state (Surface 6, variant 2); submit temporarily disabled
  423 locked                → error state (Surface 6, variant 3); submit disabled
  5xx / network             → error state (Surface 6, variant 4); submit re-enabled
 ```
 ### Password show/hide
 Toggle button (Surface 5): clicking switches `type` between `"password"` and `"text"`.
 The toggle state resets to hidden (`type="password"`) when the field loses focus.
 `aria-pressed` reflects current show state.
 ### OIDC button (Surface 9)
 Rendered only when `oidcEnabled === true`. Clicking initiates OIDC authorization-code flow
 (same redirect as today). No loading state — the redirect is immediate.
 ### Focus management
 - On page mount, focus moves to the username field (autofocus — login form is the only content)
 - On submit error, focus moves to the heading of Surface 6 (`tabIndex={-1}`, `ref` + `.focus()`)
 - On Enter key in username field: focus moves to password field
 - On Enter key in password field: submit fires (if button not disabled)
 ### Keyboard-only login
 The entire login form is keyboard-navigable. Tab order: username → password → show/hide toggle →
 "Sign in" button → "Login with OIDC" button (if shown). No tab traps outside the OIDC
 confirmation sheet.

 ## Copywriting Contract
 ### Login Screen (Surface 1–10)
 | Element | Copy |
 |---------|------|
 | App name in brand slot | "FamilySync" |
 | App tagline in brand slot | "Family calendar & lists" |
 | Login card heading | "Sign in" |
 | Username field label | "Username" |
 | Password field label | "Password" |
 | Show password toggle aria-label | "Show password" |
 | Hide password toggle aria-label | "Hide password" |
 | Primary CTA | "Sign in" |
 | Primary CTA loading state | "Signing in…" |
 | Forgot password helper | "Forgot your password? Ask your admin." |
 | Method divider label | "or" |
 | OIDC button label | "Login with OIDC" |
 | Error — invalid credentials | "Incorrect username or password." |
 | Error — rate limit | "Too many attempts. Please wait a moment and try again." |
 | Error — account locked | "This account is temporarily locked. Contact your admin to reset access." |
 | Error — server/network | "Something went wrong. Please try again." |
 | Empty state | N/A — login form always has explicit content |
 ### Admin Additions (Surfaces 11–13)
 | Element | Copy |
 |---------|------|
 | Section label | "LOCAL ACCOUNTS" |
 | Add member form heading | "Add member" |
 | Display name field label | "Display name" |
 | Username field label | "Username" |
 | Initial password field label | "Initial password" |
 | Confirm password field label | "Confirm password" |
 | Add member submit button | "Add member" |
 | Error — username taken | "That username is already in use. Choose a different one." |
 | Error — passwords mismatch (create) | "Passwords do not match." |
 | Error — password too short | "Password is too short. Use at least 8 characters." |
 | Admin reset sheet heading | "Reset password" |
 | Admin reset new password label | "New password" |
 | Admin reset confirm label | "Confirm new password" |
 | Admin reset submit button | "Reset password" |
 | SettingsSheet — change password row | "Change password" |
 | Self-change sheet heading | "Change password" |
 | Self-change current password label | "Current password" |
 | Self-change new password label | "New password" |
 | Self-change confirm label | "Confirm" |
 | Self-change submit button | "Change password" |
 | Self-change error — wrong current | "Current password is incorrect." |
 | Self-change error — passwords mismatch | "Passwords do not match." |
 | SettingsSheet — link OIDC row | "Link OIDC identity" |
 | Link OIDC sheet heading | "Link OIDC identity" |
 | Link OIDC sheet body | "After linking, you'll sign in with your OIDC provider instead of a username and password. Your local password will be removed." |
 | Link OIDC secondary note | "This can't be undone from the app. Contact your admin if you need to revert." |
 | Link OIDC cancel button | "Cancel" |
 | Link OIDC confirm button | "Continue with OIDC" |
 | Link OIDC post-redirect error (409) | "This OIDC identity is already linked to another account. Please contact your admin." |
 | Admin member row CTA — reset (local user) | "Reset password" |
 | Generic admin error | "Something went wrong. Please try again." |
 ### Copywriting rules (D-06 BYO-Auth principle)
 - Never use the word "Authelia" in any user-facing copy. Use "your OIDC provider" or
  "Login with OIDC" everywhere.
 - Never say "delete" or "remove" when describing the OIDC-link consequence — use
  "your local password will be removed" (passive, factual, non-alarming).
 - Admin copy ("Reset password") is direct — admins are comfortable with technical vocabulary.
 - End-user copy ("Sign in", "Forgot your password? Ask your admin.") is warm and low-friction —
  optimized for the non-technical Apple household member.

 ## Destructive Actions
 | Action | Trigger | Confirmation approach |
 |--------|---------|----------------------|
 | Link OIDC identity (removes local credential for that user) | "Link OIDC identity" in SettingsSheet → "Continue with OIDC" tap | Two-step: open confirmation sheet (step 1, explains consequence) + explicit "Continue with OIDC" tap (step 2). The confirmation sheet clearly states "your local password will be removed." No additional modal/dialog beyond this sheet. |
 | Admin password reset | "Reset password" in admin member row → sheet submit | Two-step: open reset sheet (step 1) + explicit "Reset password" tap with filled-in new password (step 2). No separate confirmation dialog — the act of filling and submitting a new value is the acknowledgement. |
 No hard-delete of local accounts in this phase. Account removal is out of scope.
 ---
 ## Accessibility Contract
 ### Login page (Surfaces 1–10)
 - `role="main"` on the content column
 - `<h1>` is the app name "FamilySync" in the brand slot (page-level heading);
  `<h2>` is "Sign in" (login card heading)
 - Username input: `id="login-username"`, `<label htmlFor="login-username">`, `spellCheck={false}`,
  `autoCapitalize="none"`, `autoCorrect="off"`
 - Password input: `id="login-password"`, `<label htmlFor="login-password">`, `aria-describedby="login-error"` (when error active)
 - Error container: `id="login-error"`, `role="status"`, `aria-live="polite"`, `aria-atomic="true"` —
  screen readers announce errors without focus movement
 - Show/hide toggle: `aria-pressed`, `aria-label="Show password"` / `"Hide password"`, 44px tap target
 - Submit button: `disabled` attribute (not just `pointer-events: none`) when disabled
 - Focus on mount: `autoFocus` on username field
 - Focus management on error: move focus to error heading (`tabIndex={-1}`, `.focus()`)
 - OIDC button: `type="button"`, descriptive label (no ambiguous icon-only)
 - Focus ring: `var(--color-focus-ring)` (#4a90d9), 2px outline, 2px offset on all focusable elements
 ### Admin additions (Surfaces 11–13)
 - All sheets: `role="dialog"`, `aria-modal="true"`, `aria-label` matching heading, Escape closes,
  focus returns to trigger element on close
 - All password fields: `type="password"`, correct `autoComplete` values (never cross-contaminate
  new-password / current-password)
 - Field errors: `aria-describedby` from input to its specific inline error element
 - Sheet heading: `<h2>` (heading hierarchy under page `<h1>`)
 - Minimum touch targets: `minHeight: 44px; minWidth: 44px` on all buttons
 ---
 ## Responsive Behavior
 The login page is **phone-first** (the primary user is on mobile — CLAUDE.md hard UX constraint).
 - Phone (<768px): card fills viewport minus `var(--space-6)` horizontal padding (12px each side);
  brand slot centered; no bottom tab bar; no AppNav
 - Desktop (≥768px): card centered at maxWidth 400px; brand slot centered above it
 - At all breakpoints: no AppNav, no BottomTabBar rendered on the login page
 Admin additions (Surfaces 11–13) follow the existing AdminPage responsive pattern:
 - Mobile: bottom sheet for all sheets (borderRadius 12px top corners, slides up)
 - Desktop: centered modal (maxWidth 480px, same as CredentialSheet)
 - Add-member form (Surface 11A) is inline within `/admin` content, not a sheet
 ---
 ## Security Display Rules
 Hard UI rules — not implementation notes:
 - Password fields always render as `type="password"` initially — show/hide is explicit user action
 - No password is ever pre-filled, echoed, or returned to the UI after save
 - Password values are never written to localStorage, sessionStorage, or any client-side store
 - Error messages for invalid credentials do NOT indicate which field is wrong
  (timing-safe: same copy for "wrong username" and "wrong password")
 - No `dangerouslySetInnerHTML` anywhere on the login page (project convention T-05-24)
 - The OIDC button label never contains provider-specific branding that would leak infrastructure
  details (D-06)
 - The "Link OIDC identity" flow is only accessible to an already-authenticated local user —
  never from the unauthenticated login page

 ## Registry Safety
 | Registry | Blocks Used | Safety Gate |
 |----------|-------------|-------------|
 | shadcn official | none — not initialized | not applicable |
 | third-party | none | not applicable |
 No third-party component registries. All components hand-rolled following existing project
 convention. No new npm dependencies for UI are required beyond lucide-react (already installed;
 new icons needed: `Lock`, `User`, `Eye`, `EyeOff`, `LogIn` — all available in lucide-react).

 ## Pre-Population Sources
 | Decision | Source | Value |
 |----------|--------|-------|
 | Spacing scale | apps/pwa/src/styles/tokens.css | --space-1 through --space-12; no new tokens |

 | Admin section label style | AdminPage.tsx | sectionLabelStyle (13px/600/uppercase/0.06em) |
 | Bottom sheet pattern | CredentialSheet.tsx | role="dialog", aria-modal, Escape, focus-return, borderRadius 12px top |
 | Button styles | SetupPage.tsx / AdminPage.tsx | Filled accent + ghost button — exact match |
 | Input style | SetupPage.tsx | Same inputStyle(hasError) — border switches to destructive on error |
 | No OIDC-specific branding | CONTEXT.md D-06 | Never "Authelia"; use "Login with OIDC" / "your OIDC provider" |
 | Local-only + OIDC-optional coexistence | CONTEXT.md D-01/D-02 | localEnabled always true; oidcEnabled from /api/auth/mode |
 | OIDC link removes local credential | CONTEXT.md D-12 | Confirmation sheet required; copy non-alarming |
 | No email password reset | CONTEXT.md D-11 | "Ask your admin" copy only |
 | Admin creates accounts only (no self-signup) | CONTEXT.md D-10 | Add member form is admin-only |
 | Stateless JWT session cookie | CONTEXT.md D-05 | No session table UI; logout = clear cookie |
 | Break-glass is CLI/env only | CONTEXT.md D-13 | No break-glass UI in scope |

 # Phase 19: Local Auth (No-OIDC Mode) Verification Report
 **Phase Goal:** Let an operator run FamilySync entirely on local DB users with no OIDC — username/password accounts and a local login flow that coexists with the Authelia OIDC path — and optionally wire OIDC in later by claiming/linking an existing local user to an OIDC identity. Removes the hard dependency on a deployed Authelia for small/solo self-hosters.
 **Verified:** 2026-06-17T17:51:00Z
 **Status:** gaps_found
 **Re-verification:** No — initial verification
 ## Goal Achievement
 ### Observable Truths
 | # | Truth | Status | Evidence |
 |---|-------|--------|----------|
 | 1 | A password can be hashed and the same password verifies true; a wrong password verifies false | VERIFIED | `localCredentials.ts` exports `hashPassword`/`verifyPassword`; 5/5 tests pass in `tests/auth/localCredentials.test.ts` |
 | 2 | `verifyPassword` returns false (never throws) on a malformed stored hash | VERIFIED | Test 4 in `localCredentials.test.ts` confirms try/catch wraps all crypto errors |
 | 3 | A signed local-session JWT round-trips: issue then verify returns the same userId | VERIFIED | Test 1 in `localSession.test.ts` passes; `Jwt.sign`/`Jwt.verify` HS256 with `LOCAL_SESSION_SECRET` |
 | 4 | An expired or tampered local-session token verifies to null, never throws | VERIFIED | Test 3 in `localSession.test.ts` passes; `verifyLocalSessionCookie` wraps `Jwt.verify` in try/catch |
 | 5 | The API process refuses to boot (exit 1) when `LOCAL_SESSION_SECRET` is missing/short and dev-bypass is off | VERIFIED | `assertLocalSessionSecretSet()` in `bootGuards.ts` (line 53); called from `index.ts` line 230; test confirms exemption for DEV_AUTH_BYPASS=true |
 | 6 | The `local_credentials` table exists after migration with unique user_id and unique username | VERIFIED | `0003_warm_deathstrike.sql` has `UNIQUE(user_id)` + `UNIQUE(username)` + FK; migration applied; schema exports `localCredentials` |
 | 7 | An admin can create a local member (users row + local_credentials row with a hashed initial password) in one transaction | VERIFIED | `POST /api/admin/members` in `admin.ts` uses `db.transaction`; Test 1 + Test 2 in `admin.test.ts` pass (transaction rollback on dup username) |
 | 8 | Creating a member with an already-used username returns 409, not a 500 or a partial insert | VERIFIED | ER_DUP_ENTRY detection in `admin.ts` returns 409; Test 2 confirms no users row created |
 | 9 | An admin can reset any local member's password without knowing the current one | FAILED | API route `POST /api/admin/members/:id/password` is correctly implemented and tested, but **`client.ts` `fetchAdminResetPassword` calls `/api/admin/members/${memberId}/reset-password`** — path mismatch causes 404 in production |
 | 10 | A user can change their own password only after verifying their current password | VERIFIED | `POST /api/me/password` calls `verifyPassword(current)` before `hashPassword(new)`; Test 2 confirms wrong current → 401, hash unchanged |
 | 11 | `GET /api/me` returns `hasLocalCredential` so the PWA knows whether to show Change-password / Link-OIDC | VERIFIED | `resolveAdminAndSetupStatus` selects from `local_credentials` and returns `hasLocalCredential: Boolean(localCred)`; Tests 4 + 5 in `me.test.ts` pass |
 | 12 | Linking an OIDC identity binds iss+sub to the current user and deletes their local_credentials row; a conflicting iss+sub is rejected (409) and no local row is deleted | VERIFIED | `linkOidcToUser` in `linkOidc.ts`: preflight SELECT + db.transaction(UPDATE users + DELETE local_credentials); Tests 1 + 2 in `me.test.ts` pass |
 | 13 | A valid username+password POST to `/api/auth/local/login` returns 200 and sets a local-session cookie | VERIFIED | `localAuth.ts` Test 1 in `localAuth.test.ts` passes (200 + Set-Cookie) |
 | 14 | A wrong password and an unknown username both return the same 401 with the same body (no enumeration, no field discrimination) | VERIFIED | `DUMMY_HASH` timing defense; Test 3 in `localAuth.test.ts` confirms identical 401 body; test passes |
 | 15 | After 5 failed attempts the endpoint returns 429; after 10 it returns 423 until an admin reset | VERIFIED | `loginAttempts` Map; counter increments on 429 path too; Tests 4 + 5 in `localAuth.test.ts` pass |
 | 16 | A request carrying a valid local-session cookie resolves `c.get('user')` and is NOT 302-redirected to OIDC | VERIFIED | `localAuthMiddleware` sets `c.get('user')`; OIDC guard wrapped with `if (c.get('user')) { next(); return; }` in `index.ts` line 157; middleware Tests 1 + 4 pass |
 | 17 | `GET /api/auth/mode` is reachable pre-auth and returns `{ localEnabled:true, oidcEnabled }` reflecting app_config/env | VERIFIED | `authModeRouter` mounted before devAuthBypass (line 114 of index.ts); Tests 5/6/6b in `authMode.test.ts` pass |
 | 18 | Logout clears the local-session cookie | VERIFIED | `clearLocalSessionCookie` called on `POST /api/auth/local/logout` and `GET` alias; Test 6 + 6b pass |
 | 19 | An unauthenticated user with no valid session lands on `/login` (when localEnabled) and sees the brand slot + username/password form | VERIFIED | App.tsx `authModeQuery` gate; `App.test.tsx` Phase 19 describe block passes; `LoginPage.tsx` has id="login-username", "Sign in" heading; `BrandSlot` component renders |
 | 20 | No user-facing string or config comment says "Authelia" | VERIFIED | All modified API and PWA source files return 0 case-insensitive matches for "authelia" in user-facing code (one occurrence in SettingsSheet.tsx is a comment prohibiting the word, not user-facing) |
 | 21 | An admin sees a LOCAL ACCOUNTS section to add a member and a per-member Reset-password action | PARTIAL | LOCAL ACCOUNTS section exists in `AdminPage.tsx` (line 691); add-member form is wired to `fetchCreateMember` (correct URL `/api/admin/members`); Reset-password button exists gated on `hasLocalCredential`, but `fetchAdminResetPassword` calls wrong URL — see gap for truth #9 |

 ### Anti-Patterns Found
 | File | Line | Pattern | Severity | Impact |
 |------|------|---------|----------|--------|
 | `apps/pwa/src/api/client.ts` | 204 | Wrong URL in `fetchAdminResetPassword` — calls `/reset-password` instead of `/password` | Blocker | Admin password reset 404s in production |

 No unreferenced TBD/FIXME/XXX debt markers found in Phase 19 files.
 ### Human Verification Required
 #### 1. Login Page Visual + Flow Verification
 **Test:** Using playwright-cli against the non-bypass stack (or deploy stack), navigate to the PWA without a session. Confirm /login renders with BrandSlot ("FamilySync", "Family calendar & lists"), Sign in heading, username + password fields with show/hide toggle. Test all 4 error states.
 **Expected:** BrandSlot visible at top; form renders with id="login-username" and id="login-password"; submitting wrong credentials shows exactly "Incorrect username or password." (no field blame); submitting correct credentials navigates into the app. When oidcEnabled, "or" divider + "Login with OIDC" button appear (no "Authelia").
 **Why human:** LoginPage renders in a real browser; DEV_AUTH_BYPASS prevents real login-gate testing under dev harness. playwright-cli can drive /login directly (not the gate redirect) in Chromium.
 #### 2. Admin Reset Password (After Fixing Gap)
 **Test:** After fixing the `fetchAdminResetPassword` URL in `client.ts`, log in as admin, open /admin, expand LOCAL ACCOUNTS for a member with `hasLocalCredential:true`, click Reset-password, enter a new password, submit.
 **Expected:** 200 from `POST /api/admin/members/:id/password`; the member can then log in with the new password.
 **Why human:** The gap (URL mismatch) must be fixed first; then requires a live admin session with real local credential data.
 #### 3. Settings Change-Password Flow
 **Test:** Log in as a local user. Open Settings. Confirm "Account" section with "Change password" row visible (only when hasLocalCredential). Click, enter wrong current password — confirm "Current password is incorrect." error. Enter correct current and new password — confirm success.
 **Expected:** Current password validation works server-side (401 on wrong current); hash updated on success; new password works on next login.
 **Why human:** Requires live stack with a local user session; involves stateful password update.
 #### 4. Rate-Limit Flakiness Characterization
 **Test:** Run `pnpm --filter @familysync/api test tests/routes/localAuth.test.ts` 10 times in sequence and note pass rate for Test 5 (10 failures → 423).
 **Expected:** 10/10 pass. Orchestrator noted one intermittent failure across 3 run history.
 **Why human:** Timing-dependent in-memory state machine; could be flaky under CI load; needs repeated observation to characterize.
 ---
 ## Gaps Summary
 ### 1. `fetchAdminResetPassword` URL Mismatch (AUTH-LOCAL-08 / AUTH-LOCAL-13)
 **Root cause:** `apps/pwa/src/api/client.ts` line 204 calls `/api/admin/members/${memberId}/reset-password` but the API registers the route as `POST /api/admin/members/:id/password` (in `apps/api/src/routes/admin.ts` line 212). These paths are different — `/reset-password` vs `/password`.
 **Impact:** The Admin page "Reset password" sheet (`AdminPage.tsx` → `ResetPasswordSheet` → `fetchAdminResetPassword`) will receive a 404 response on every submit in a production (non-mocked) environment. The underlying API endpoint is correctly implemented and tested; only the client URL is wrong.
 **API tests pass** because `admin.test.ts` calls the correct `/api/admin/members/${newMemberId}/password` path directly via `jsonRequest`, not via `client.ts`.
 **Fix:** Change line 204 of `client.ts`:
 ```typescript
 // Wrong:
 const res = await fetch(`/api/admin/members/${memberId}/reset-password`, {
 // Correct:
 const res = await fetch(`/api/admin/members/${memberId}/password`, {
 ```
 This is a one-line fix. No API change needed.

 * Local authentication credentials per member (Phase 19 — D-09).

 * Stores username + PHC-encoded scrypt password hash for members who authenticate
 * via local username/password rather than (or before) OIDC.
 *
 * Design decisions:
 *   - Separate table from `users` to keep the users row identity-method-agnostic (D-09).
 *   - A user has a local login iff a `local_credentials` row exists (UNIQUE on user_id).
 *   - OIDC-link flow (D-12): when a local user links OIDC, their `local_credentials`
 *     row is deleted — they become OIDC-only.
 *   - CASCADE DELETE on users.id keeps credentials clean when a member is removed.
 *   - username is globally unique (login identifier, separate from displayName).
 *   - password_hash is PHC-encoded: scrypt$N$r$p$<salt_b64url>$<hash_b64url> (varchar 256).
 *
 * PROHIBITION: LOCAL_SESSION_SECRET (the signing key for this table's sessions) is an
 * env-only secret and must NEVER be stored in this table or app_config (SC-3).

 /**
 * login.spec.ts — Phase 19 AUTH-LOCAL-12/15/16
 *
 * Real-login-form e2e tests covering the PWA login gate + form interaction.
 *
 * Strategy (Option C):
 *   The global-setup seeds 'devuser'/'devpass' into local_credentials and the API's
 *   devSessionCookieMiddleware issues a local-session cookie on every /api/* request
 *   under DEV_AUTH_BYPASS=true. The OTHER specs (layout, calendar, lists) rely on that
 *   cookie being present and do NOT clear it — they still reach the authed app unchanged.
 *
 *   IMPORTANT — bypass constraint: this harness is DEV_AUTH_BYPASS-only (global-setup
 *   refuses a non-bypass DB). Under the bypass, devAuthBypass() injects DEV_USER into
 *   every /api/* request, so /api/me is authed regardless of the local-session cookie —
 *   clearing the cookie does NOT produce a logged-out state in the browser. We therefore
 *   exercise the /login page DIRECTLY (the /login route always renders the form) for the
 *   form + real-login round-trip, and cover the unauthenticated root→/login redirect gate
 *   at the unit level in src/App.test.tsx (where meQuery.isError is controllable).
 *
 * Specs covered:
 *   1. /login renders all brand + form surfaces (real browser, real CSS/tokens)
 *   2. Wrong password → single "Incorrect username or password." error message
 *   3. Correct devuser/devpass → navigates into the app (out of /login)
 *
 * Only runs on the desktop/chromium project (Chromium handles local-session cookies
 * consistently; WebKit PWA restrictions are irrelevant here since the login form is
 * a normal web page, not a Home Screen PWA). Other profiles inherit the bypass cookie.
 *
 * Run:
 *   pnpm --filter @familysync/pwa test:e2e --grep "login"
 *   pnpm --filter @familysync/pwa exec playwright test --project=desktop login.spec.ts

 * BrandSlot — Phase 17 seam component for the login page brand area.
 *
 * Phase 19 ships a minimal shippable placeholder: a 48px circle with "FS"
 * initials, the app name "FamilySync", and the tagline "Family calendar & lists".
 *
 * Phase 17 replaces the internals of this component (swap the placeholder div for
 * an <img> with a real logo) without touching LoginPage's layout. This isolates
 * the branding seam — see 19-UI-SPEC.md §Brand Slot section.
 *
 * CSS custom properties used (all set in tokens.css with placeholder defaults;
 * Phase 17 overrides these values):
 *   --brand-logo-bg           — logo circle background (default: var(--color-member-0))
 *   --brand-logo-text         — initials color (default: #ffffff)
 *   --brand-logo-size         — circle diameter (default: 48px)
 *   --brand-logo-border-radius — circle shape (default: 50%)
 *
 * Accessibility:
 *   <h1> contains the app name — screen readers read "FamilySync" as the page title.
 *   The logo circle is aria-hidden (the text is the accessible label).
 *   No <img> today → no broken image ref → no layout shift when Phase 17 replaces it.
 *
 * Security: all copy is plain-text JSX children — no dangerouslySetInnerHTML (T-05-24).

 * Two-step confirmation: open sheet (step 1) + tap "Continue with OIDC" (step 2).
 *
 * Copywriting rules (UI-SPEC §Copywriting Contract):
 *   - Never use "Authelia" (D-06) — use "your OIDC provider"
 *   - Never say "delete" or "remove" when describing consequence — use "will be removed" (passive)
 *   - Body copy: non-alarming, frames linking as an upgrade

 * Security: T-19-21 — no provider-specific branding that leaks infrastructure details.

 * LoginPage — standalone /login route (Phase 19, D-04).
 *
 * UI-SPEC §Surface Architecture Surfaces 1–10:
 *   Surface 1: Full-page standalone route (no AppNav/BottomTabBar/SetupBanner)
 *   Surface 2: BrandSlot — app logo placeholder + name + tagline (Phase 17 seam)
 *   Surface 3: Login card — "Sign in" heading
 *   Surface 4: Username field (id="login-username", spellCheck/autoCapitalize/autoCorrect off)
 *   Surface 5: Password field with show/hide toggle (Eye/EyeOff, 44px tap target)
 *   Surface 6: Error/lockout banner (role="status", aria-live="polite", 4 error variants)
 *   Surface 7: Primary "Sign in" / "Signing in…" submit button (full-width)
 *   Surface 8: Method divider ("or") — rendered only when oidcEnabled
 *   Surface 9: "Login with OIDC" outlined button — rendered only when oidcEnabled
 *   Surface 10: "Forgot your password? Ask your admin." helper (informational only)
 *
 * Auth gate: App.tsx renders this route when meQuery returns 401 AND localEnabled.
 * On success: window.location.replace('/') — the cookie is set by the API server.
 *
 * Security:
 *   T-19-18: password field is controlled state only; never written to localStorage/sessionStorage
 *   T-19-19: single shared "Incorrect username or password." — no field-level blame
 *   T-19-20: plain-text JSX children; no dangerouslySetInnerHTML (T-05-24)
 *   T-19-21: D-06 — UI never renders the provider name; uses generic "Login with OIDC"
