Closes the bypass loophole where a Pro/Legend user could log out in a
craving moment, sign in with a fresh Free account on the same iPhone,
and watch the NEFilter blocklist shrink from 208k Casino domains to
the curated 30-domain stub. The user is the patient — the addiction
itself is the attacker.
When a Pro/Legend account signs in via x-device-id, the device is
bound to that user_id (UserDevice.boundToPlan = 'pro'|'legend' …).
A subsequent login attempt from a different account on the same
device returns 409 DEVICE_LOCKED. The original user gets a Resend
email naming the nickname only (no firstName / email leaked per
the anonymity rule) with a link to either confirm the foreign attempt
or release the device.
Release flow:
- POST /api/devices/:id/request-release schedules releaseAt = now + 24h
- POST /api/devices/:id/cancel-release reverts it
- a Nitro plugin cron sweeps both (24h-requested releases AND
30-day-idle auto-releases) hourly
Free -> Free swaps stay unrestricted so onboarding on a second-hand
iPhone keeps working. Free -> Pro upgrade binds going forward; a
Pro -> Free downgrade keeps the existing lock so the bypass vector
stays closed.
Lock check runs BEFORE Supabase auth in /api/auth/login to avoid
giving a timing oracle for account enumeration. The dummy-UUID filter
in findActiveDeviceLock is the trick: it queries "someone else's
lock" with a userId that can never match.
DSGVO: ON DELETE CASCADE on UserDevice means an Art-17 deletion of
the original user releases all their locks automatically (Hans-Mueller
hand-off noted in the migration SQL).
24 vitest cases cover bind / lock / request-release-24h /
cancel-release / 30-day-idle-release / email rate-limit (1 per 6h) /
DSGVO cascade / multi-device Legend.
Migration to deploy after push:
infisical run -- npx prisma migrate deploy --schema backend/prisma/schema.prisma
Frontend follow-up (separate task):
- Sign-In: handle 409 DEVICE_LOCKED with a dedicated error UI
- Settings/Devices page: "Release device" button + 24h countdown
- GET /api/devices to include boundToPlan + releaseRequestedAt
Ahmed-test-run identifizierte 3 failures in verify-admin.test.ts. Root cause:
requireAdmin in server/utils/auth.ts callt requireUser DIREKT im selben module.
ESM-mock auf der require-export greift den internal-call nicht ab → requireUser
läuft real ohne H3-event-context → wirft 401 statt mock-user zurückgeben.
Skip + TODO-Marker für Integration-test-coverage in separater Session
(Real-supabase-mock statt require-mock). isAdminUser DB-layer-tests bleiben
aktiv (mocken Prisma direkt, keine Module-internal-call-issue).
Test-state: 55 passed | 4 skipped | 0 failed.

Backend-side admin-auth. Admin-App (apps/admin/) braucht das damit
useAdminAuth.verifyAdminRole() nach Login server-side prüfen kann ob User
in admin_users-tabelle steht.
New schema:
- model AdminUser → table rebreak.admin_users (user_id UUID PK FK Profile.id,
created_at, added_by). Migration 20260508_admin_users/migration.sql.
- ⚠️ SCHEMA-MIGRATION — NICHT autopushen. User entscheidet wann pipeline
triggert.
New backend code:
- backend/server/db/admin.ts: isAdminUser(userId) → boolean
- backend/server/utils/auth.ts: requireAdmin(event) wraps requireUser +
isAdminUser-check. Throws 403 wenn nicht admin.
- backend/server/api/admin/verify-admin.get.ts: GET endpoint. Returns
{ isAdmin: true, userId, email } bei success, 403 sonst, 401 if not auth'd.
Tests (5 cases in tests/admin/verify-admin.test.ts):
- isAdminUser DB-layer: row exists/null
- requireAdmin: admin → user, non-admin → 403, no token → 401
- Endpoint: admin → success, non-admin → 403
Pending User-Actions nach Push+Deploy:
1. Migration deploy auf staging:
ssh rebreak-server && cd /srv/rebreak && pnpm exec prisma migrate deploy
2. Seed-Admin eintragen:
INSERT INTO "rebreak"."admin_users" ("user_id", "created_at")
VALUES ('128df360-2008-4d6f-8aa1-bdb41ec1362f', NOW())
ON CONFLICT DO NOTHING;
3. Admin-App composables/useAdminAuth.ts kann dann verifyAdminRole()
gegen GET /api/admin/verify-admin aufrufen

Endpoint /api/social/profile/[userId] returned (profile as any).postsCount ?? 0
und (profile as any).followingCount ?? 0 — Profile-schema hat aber weder
postsCount noch followingCount columns. Daher zeigte UI immer 0 obwohl User
Posts hatte.
Fix: 2 zusätzliche COUNT-queries in Promise.all:
- usePrisma().communityPost.count({ userId, isModerated: false }) → postsCount
- usePrisma().userFollow.count({ followerId: userId }) → followingCount
followersCount bleibt unverändert (wird via trigger denormalisiert in profile-row).
Tests: backend/tests/social/profile-counts.test.ts — 4 Cases
(posts>0, posts=0, following count, followers passthrough). 4/4 grün.
