- src/lib/auth/bearer.ts is the single identity dispatch for both
server-side token consumers (RSC apiFetch and the /api proxy route):
local -> httpOnly tc_session cookie; clerk -> Clerk getToken() session
JWT. The Clerk SDK is imported lazily, so the air-gapped/local path
never loads it
- Runtime env (AUTH_MODE / CLERK_PUBLISHABLE_KEY / CLERK_SECRET_KEY),
deliberately NOT build-time NEXT_PUBLIC_*: the same standalone image
serves both deployment targets
- Conditional <ClerkProvider> in the root layout (publishableKey passed
at render from runtime env); /login renders Clerk's <SignIn /> in
clerk mode and the local form otherwise; proxy.ts middleware delegates
to clerkMiddleware() only when active
- Helm: frontend deployment injects the Clerk keys from a Secret when
auth.mode=clerk
- mode.ts unit-tested (default local, exact-match clerk, loud failure
without the publishable key); the local path stays proven by all 29
journeys; the Clerk branch is thin delegation to the SDK, exercised in
deployment smoke per docs/clerk.md
157 Rust + 68 frontend tests + 29 Playwright journeys.

- tc-auth JwtVerifier: OIDC discovery -> JWKS, RS256 with the issuer
pinned, 5s leeway (the crate's default 60s would double the life of
Clerk's 60s session tokens), key cache with one refresh on unknown kid
(Clerk rotates). Serves auth.mode = clerk AND generic oidc — a Clerk
instance IS an OIDC issuer, so one verifier covers both
- AuthService.authenticate dispatches: JWT-shaped bearers take the
hosted-identity path, everything else stays a local opaque session.
External users JIT-provision keyed by the stable sub claim
(users.auth_subject, unique partial index in migration 0007); an
existing local account with the same email is LINKED, not duplicated;
role tracks the issuer claim every request (org:admin -> Owner)
- Config auth.mode = "clerk" (requires issuer_url; validated), server
pins the issuer at boot, Helm values/configmap accept mode=clerk
- Tests with REAL crypto, no mocks: fresh RSA keypairs, a live local
issuer publishing real discovery + JWKS docs, Clerk-shaped tokens —
JIT + role mapping, repeat-subject no-dup, expired refused (leeway
regression), wrong-key forgery refused, foreign issuer refused, and
the full router round trip with Authorization: Bearer <session JWT>
- docs/clerk.md: dashboard session-token customization (email + org
role claims), config, @clerk/nextjs getToken() wiring, what CI proves
157 Rust + 63 frontend tests + 29 journeys. Air-gapped installs keep
local auth — Clerk is a cloud-only alternative, not a replacement.
