Marc-André Bombeck e6d9cc229a feat(auth): native OIDC SSO session handoff for the iOS client
The web OIDC flow ends in a session cookie the Bearer-transport native
client cannot consume, so on an OIDC_ONLY instance the iOS app had no
sign-in. Add a native leg: the app opens the login URL with
client=native and its own PKCE S256 challenge inside an in-app browser;
the callback resolves identity exactly as before, then mints a one-time
handoff code and 302s to the fixed compiled-in scheme
healthlog://oidc-callback (or hands back the existing MFA ticket when
the account has a second factor). The app exchanges the code plus its
PKCE verifier at POST /api/auth/oidc/native/token for the standard
native token bundle.

The return address is a compile-time constant — no redirect_uri
parameter and no env allowlist, so the open-redirect / scheme-hijack
class is removed by construction. The native flag and app challenge
travel only inside the AES-256-GCM state blob, so a network attacker or
the IdP cannot flip a web login into a native one. The handoff code is
256-bit CSPRNG, HMAC-hashed at rest, 90-second TTL, single-use via a
guarded consume; a failed PKCE check burns it. A replay of a consumed
code revokes exactly the pair the first exchange issued. The token pair
never rides a URL; only the opaque code or the MFA ticket do. The SSO
login can never satisfy requireFreshMfa step-up — the transport is
Bearer and step-up is cookie-only.

Adds the OidcNativeHandoff model (migration 0252), the token-exchange
route, a daily cleanup sweep, and the OpenAPI entry.

prisma/

The database layer. HealthLog runs PostgreSQL 16 via Prisma 7. This directory holds the single schema file and the forward-only migration history; the generated client is emitted elsewhere.

Contents

  • schema.prisma — 61 models, one file. cuid() primary keys, snake_case columns via @map(...), encrypted columns mostly suffixed *Encrypted (search the file; there are 24 encrypted column references). The generator client block emits to ../src/generated/prisma (imported as @/generated/prisma).
  • migrations/ — numbered, forward-only SQL migrations (0001_… upward). migration_lock.toml pins the provider to postgresql.

Migration workflow

# author a migration from a schema edit
pnpm dlx prisma migrate dev --name <short_snake_case_name>

# regenerate the client after any schema change
pnpm dlx prisma generate

Number a new migration with the next free prefix. The production entrypoint runs prisma migrate deploy on boot, so every migration must apply cleanly forward — there is no down-migration path. Always include the migration file in the same change as the schema edit.

Conventions

  • Encryption is fail-closed: *Encrypted columns are written through @/lib/crypto (AES-256-GCM, versioned key ids); never store plaintext in an encrypted column. Key rotation is scripts/rotate-encryption-key.ts + docs/ops/encryption-key-rotation.md.
  • The generated client under src/generated/prisma is build output — do not edit it.
  • Schema-touching changes that affect the API surface must regenerate docs/api/openapi.yaml (see ../CLAUDE.md).
