# Phase 260610-k1z: Persist OIDC Session Cookie with Max-Age — Verification Report

**Phase Goal:** Persist the OIDC session cookie with maxAge so PWA/browser sessions survive close — WITHOUT ever resurrecting a deleted/logged-out session.
**Verified:** 2026-06-10T18:35:00Z
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Truthy oidcAuthJwt → response re-sets oidc-auth cookie with Max-Age, SameSite=Lax, HttpOnly, Secure | VERIFIED | `persistSessionCookie.ts` lines 47–76: guard passes, `setCookie(c, name, jwt, { httpOnly:true, secure:true, sameSite:'Lax', maxAge, ... })` called before `await next()` |
| 2 | Falsy/absent oidcAuthJwt → NO oidc-auth Set-Cookie emitted (no resurrection guard) | VERIFIED | Lines 47–50: `if (!jwt) { await next(); return }` — hard early exit before any `setCookie` call; covered by Test B (absent) and guard variant (empty string), both passing |
| 3 | Cookie carries httpOnly:true, secure:true, sameSite:'Lax'; domain included only when OIDC_COOKIE_DOMAIN set | VERIFIED | Options object built lines 63–69 (always includes httpOnly/secure/sameSite); `if (process.env.OIDC_COOKIE_DOMAIN)` guard at line 71 adds domain key only when env var is set — key absent (not undefined) when unset |
| 4 | `pnpm --filter @familysync/api typecheck` exits 0 | VERIFIED | Run output: `$ tsc --noEmit` — exit 0, no diagnostic output |

**Score:** 4/4 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `apps/api/src/auth/persistSessionCookie.ts` | persistSessionCookie() MiddlewareHandler; min 25 lines | VERIFIED | 81 lines; exports `persistSessionCookie(): MiddlewareHandler`; imports only `hono` and `hono/cookie` — no new dependencies |
| `apps/api/tests/auth/persistSessionCookie.test.ts` | Vitest unit tests; contains "persistSessionCookie" | VERIFIED | 123 lines; 4 tests across 2 describe groups; pure unit test (no MariaDB, no @hono/oidc-auth import) |
| `apps/api/src/index.ts` | Mounts persistSessionCookie immediately after oidcAuthMiddleware inside !devBypassActive | VERIFIED | Line 14: import present; lines 52–54: `app.use('/api/*', oidcAuthMiddleware())` followed immediately by `app.use('/api/*', persistSessionCookie())` — both inside `if (!devBypassActive)` block |

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| `apps/api/src/index.ts` | `apps/api/src/auth/persistSessionCookie.ts` | `import { persistSessionCookie } from './auth/persistSessionCookie.js'` + `app.use('/api/*', persistSessionCookie())` inside `if (!devBypassActive)` | VERIFIED | Import at line 14; usage at line 54; ordering correct — line 53 oidcAuthMiddleware, line 54 persistSessionCookie |
| `apps/api/src/auth/persistSessionCookie.ts` | oidcAuthJwt context var (@hono/oidc-auth) | `c.get('oidcAuthJwt' as never)` read; cookie re-issued only when truthy | VERIFIED | Line 40: `const jwt = c.get('oidcAuthJwt' as never) as string | undefined`; line 47: falsy guard; no import of @hono/oidc-auth |

### Behavioral Spot-Checks (Vitest)

| Behavior | Command | Result | Status |
|----------|---------|--------|--------|
| Full tests/auth/ suite | `pnpm --filter @familysync/api exec vitest run tests/auth/` | 3 test files, 14 tests, all passed | PASS |
| Test A — persist path (Max-Age + SameSite=Lax + HttpOnly + Secure present) | included in suite above | passes | PASS |
| Test A variant — same JWT value re-issued unchanged | included in suite above | passes | PASS |
| Test B — guard path (absent oidcAuthJwt → no Set-Cookie) | included in suite above | passes | PASS |
| Test B variant — empty string oidcAuthJwt → no resurrection | included in suite above | passes | PASS |

### Anti-Patterns Found

None. No TBD/FIXME/XXX markers, no placeholder returns, no empty handlers, no hardcoded empty data in modified files. `persistSessionCookie.ts` is fully implemented; all three modified files are substantive.

### Scope Constraint Verification

| Constraint | Status | Evidence |
|------------|--------|----------|
| No changes to @hono/oidc-auth | VERIFIED | Only files modified: persistSessionCookie.ts (new), index.ts (import + 2 lines), persistSessionCookie.test.ts (new) |
| No changes to package.json | VERIFIED | No package.json in modified files list; only `hono/cookie` used, which ships with the existing `hono` dependency |
| No changes to .env | VERIFIED | Not in modified files list |
| Cookie set BEFORE await next() | VERIFIED | `setCookie(c, name, jwt, options)` at line 76; `await next()` at line 78 |
| Middleware NOT mounted under dev bypass | VERIFIED | Both `oidcAuthMiddleware()` and `persistSessionCookie()` registrations are inside `if (!devBypassActive)` block (index.ts lines 51–55) |

### Human Verification Required

None — all behavioral properties verified programmatically via unit tests and static code analysis.
