Eighteen modules carried a convenience re-export of a symbol defined
elsewhere. In each case the callers the comment describes now import the
concrete module directly, so the line had no importer left. Where the
whole re-export block went, the comment explaining it went with it —
doctor-report-pdf-core, trend-card and medication-extract-prompt each
claimed to be a single import surface that nothing was using.
Definitions are untouched; imports that existed only to feed a removed
re-export go too.
Self-hosters can sign in to the iOS app through their own domain, so the
password manager files credentials under the right site and passkeys run in
the correct origin. The app opens the instance's own web login inside an
ASWebAuthenticationSession; after an interactive login the server mints a
single-use, PKCE-locked handoff code on a compiled-in custom scheme, which the
app exchanges for the standard native token bundle. The token pair never rides
a URL — only the opaque code does.
Three endpoints mirror the OIDC native handoff and share its mint/consume core,
now extracted to native-handoff.ts (the OIDC leg keeps working unchanged, as
the default flow):
- GET /api/auth/native/login validates the PKCE challenge, sets a
short-lived encrypted state cookie, and
redirects to /auth/login?flow=native.
- GET /api/auth/native/complete validates the web session, enforces the
freshness binding, mints the code, and
redirects to healthlog://login-callback.
- POST /api/auth/native/token exchanges the code under the cookie-less
native transport gate for the native bundle.
The freshness binding refuses any session older than the flow start, so a
pre-existing browser session can never silently complete a handoff. The start
time is stamped from the database clock (SELECT now()) to stay comparable to
Session.createdAt with no app/DB skew, and createdAt is read through a
dedicated projection so the comparison cannot be silently dropped. A flow
discriminator on the handoff row (migration 0268) makes an OIDC code
non-redeemable at the web-login route and vice versa.
The callback scheme is a compile-time constant with no redirect_uri parameter,
requireAdmin and requireFreshMfa stay cookie-only, and the exchange mints no
wider scope than password login. The state cookie is AES-256-GCM with a fresh
IV. Adds the flow=native login-page banner in all six locales and the three
routes to the OpenAPI contract.
Adversarial review found the transport gate (isCookielessNativeCaller) was
broader than finishLogin's bearer predicate: a blank-UA caller with no
X-Client-Type could pass it and fall into the cookie branch, receiving a
Set-Cookie session instead of the token bundle (inert, not exploitable, but
the endpoint's own invariant was false). Also require isNativeClientRequest
so the cookie path is structurally unreachable here, and report the actual
revoke outcome on a replay so the wide event never overclaims.
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.
