Adds the OpenID Connect login flow Dialectic.Frontend will drive. Pattern
mirrors Fabric.Backend.Center: SPA → /api/auth/oidc/start → IdP →
/api/auth/oidc/callback → 302 to SPA with one-time ticket in URL fragment
→ SPA POST /api/auth/oidc/exchange → HttpOnly session cookie set.
What's added:
- internal/oidc/service.go — runtime OIDC service:
* BuildAuthorizeURL (PKCE S256 + random state, 10min ttl)
* HandleCallback (token exchange + ID token verify + ticket mint, 60s ttl)
* ExchangeTicket (ticket → session JWT, HS256 24h)
* VerifySession (cookie validation)
* GetConfig/SetConfig with sync.Map-backed state/ticket stores
* SweepExpired (call from background goroutine; clears stale entries)
- internal/db/migrations/004_oidc_config.sql — single-row oidc_config
table (issuer/client_id/client_secret/redirect_uri/post_login_redirect/
scopes/enabled). Runtime-mutable via dialectic-cli.
- internal/httpapi/handlers/auth.go — 5 endpoints:
GET /api/auth/oidc/status — { enabled }
GET /api/auth/oidc/start — 302 to IdP
GET /api/auth/oidc/callback — IdP returns; we 302 to SPA with ticket
POST /api/auth/oidc/exchange — ticket → cookie + user
GET /api/auth/me — current session user (401 if anon)
POST /api/auth/logout — clears cookie
- internal/auth: replaces the OIDCBrowser Phase-2C stub with one that
reads the session cookie via SessionVerifier; keeps dev-bypass
behind cfg.OIDCOnly gate (set OIDC_ONLY=true in prod to disable
dev-bypass entirely)
- cmd/dialectic-cli/main.go — new binary; subcommand
'config oidc [--issuer ... --client-id ... --client-secret ...
--callback-url ... --enabled true|false]'
Runs against same DB the backend uses; reachable via
'docker exec dialectic-backend dialectic-cli config oidc ...'
- Dockerfile: build both binaries; put on PATH for docker exec
Config:
- SESSION_SIGNING_KEY env: required in prod, ephemeral random in dev.
HS256 secret for session JWTs. Stable across restarts (rotation
invalidates every session — kill switch).
- OIDC_ONLY env: 'true' disables the dev-bypass path entirely; use
in prod once OIDC is configured.
- OIDC_ISSUER + OIDC_CLIENT_ID env are no longer required at boot —
they're advisory bootstrap values for the oidc_config DB row.
Deps:
- github.com/coreos/go-oidc/v3 (discovery + JWKS verify)
- golang.org/x/oauth2 (token exchange + PKCE)
- github.com/golang-jwt/jwt/v5 (session JWT)
- Bumped go.mod toolchain to 1.25.
Pairs with Dialectic.Frontend (next commit) which removes the
/agents/:id admin page and adds the login button + /oidc/callback
SPA route + AuthProvider that talks to these new endpoints.
