Adds the server side of the per-user encryption vault. Phase 1 shipped
the client foundation (no-op while every table is enabled:false). This
commit lets the client actually fetch a master key when Phase 3 flips
the registry switches.
Schema (Drizzle + raw SQL migration)
- auth.encryption_vaults: per-user wrapped MK + IV + format version +
kek_id stamp + created/rotated timestamps. PK = user_id, ON DELETE
CASCADE so account deletion wipes the vault.
- auth.encryption_vault_audit: append-only trail of init/fetch/rotate
actions with IP, user-agent, HTTP status, free-form context.
- sql/002_encryption_vaults.sql: idempotent CREATE TABLE + ENABLE +
FORCE row-level security with a `current_setting('app.current_user_id')`
policy on both tables. FORCE makes the policy apply to the table
owner too — no bypass via grants.
KEK loader (services/encryption-vault/kek.ts)
- Loads a 32-byte AES-256 KEK from the MANA_AUTH_KEK env var (base64).
- Production: missing or wrong-length input is fatal at boot.
- Development: 32-zero-byte fallback so contributors can run the
service without provisioning a secret. Logs a loud warning.
- wrapMasterKey / unwrapMasterKey use Web Crypto AES-GCM-256 over the
raw 32-byte MK with a fresh 12-byte IV per wrap. Returns base64
pair for storage.
- generateMasterKey + activeKekId helpers used by the service.
- Future migration to KMS / Vault: only loadKek() changes; the
kek_id stamp on each row tracks which KEK produced it.
EncryptionVaultService (services/encryption-vault/index.ts)
- init(userId): idempotent — returns existing MK or mints a new one.
- getMasterKey(userId): unwraps the stored MK; throws VaultNotFoundError
on no-row so the route can return 404 cleanly.
- rotate(userId): mints fresh MK, replaces wrap. Caller is on the
hook for re-encryption — destructive by design.
- withUserScope(userId, fn): wraps every read/write in a Drizzle
transaction with set_config('app.current_user_id', userId, true)
so the RLS policy admits only the matching row. Empty userId is
rejected up-front.
- writeAudit() appends a row to encryption_vault_audit on every
action including failures, so probing attempts leave a trail.
Routes (routes/encryption-vault.ts)
- POST /api/v1/me/encryption-vault/init — idempotent bootstrap
- GET /api/v1/me/encryption-vault/key — fetch the active MK
- POST /api/v1/me/encryption-vault/rotate — destructive rotation
- All return base64-encoded master key bytes plus formatVersion +
kekId. JWT-protected via the existing /api/v1/me/* middleware.
- readAuditContext() pulls X-Forwarded-For + User-Agent off the
request for the audit row.
Bootstrap (index.ts)
- loadKek() runs at top-level await before any route can fire so a
misconfigured KEK fails closed at boot, never at request time.
- encryptionVaultService is mounted under /api/v1/me/encryption-vault
so it inherits the existing JWT middleware and shows up next to the
GDPR self-service endpoints.
Tests (services/encryption-vault/kek.test.ts)
- 11 Bun-test cases covering: KEK load (happy path, wrong length,
idempotent, before-load guard), generateMasterKey randomness,
wrap/unwrap roundtrip, IV uniqueness across repeated wraps,
wrong-MK-length rejection, tampered-ciphertext rejection,
wrong-length IV rejection, wrong-KEK rejection.
- Service-level integration tests deferred — they need a real
Postgres for the RLS behaviour, set up via existing mana-sync
test pattern in CI.
Config + env
- .env.development gains MANA_AUTH_KEK= (empty → dev fallback)
with a comment explaining the production requirement.
- services/mana-auth/package.json gains "test": "bun test".
Verified: 11/11 KEK tests passing, 31/31 Phase 1 client tests still
passing, only pre-existing TS errors remain in mana-auth (auth.ts:281
forgetPassword + api-keys.ts:50 insert overload — both unrelated).
Phase 3: client wires the MemoryKeyProvider to GET /encryption-vault/key
on login, flips registry entries to enabled:true table by table, and
extends the Dexie hooks to call wrapValue/unwrapValue on configured
fields.
Phase 4: settings UI for lock state, key rotation, recovery code opt-in.

Replace direct Brevo SMTP sending with HTTP calls to mana-notify's
notification API. This centralizes all email configuration in one
service (mana-notify) and removes the nodemailer dependency from
mana-auth. SMTP provider is now swappable via a single env var.

Rewrite the central authentication service from NestJS to Hono + Bun.
Uses Better Auth's native fetch-based handler — no Express conversion.
Key architecture changes:
- Better Auth handler mounted directly on Hono (app.all('/api/auth/*'))
- No NestJS DI, modules, guards, decorators — plain TypeScript
- JWT validation via jose (same as extracted services)
- Email via nodemailer (simplified, German templates)
- ~1,400 LOC vs ~11,500 LOC in NestJS (88% reduction)
Service structure:
- auth/better-auth.config.ts — copied from mana-core-auth (framework-agnostic)
- auth/stores.ts — in-memory stores for email redirect URLs
- email/send.ts — nodemailer email functions
- middleware/ — JWT auth, service auth, error handler (shared pattern)
- db/schema/ — copied from mana-core-auth (Drizzle, framework-agnostic)
Port: 3001 (same as mana-core-auth — drop-in replacement)
Database: mana_auth (same DB, same schemas)
Better Auth plugins: Organization, JWT (EdDSA), OIDC Provider,
Two-Factor (TOTP), Magic Link
Note: This is the initial version. Guilds, API keys, Me (GDPR),
security (lockout/audit), and admin endpoints will be added
incrementally. The old mana-core-auth remains until fully replaced.
