- internal/auth/oidc.go: OIDCService mit go-oidc v3
- id_token-Verifikation via JWKS (Signatur, iss, aud, exp)
- Provider-Caching (sync.Map, lazy init per Issuer-URL)
- Unterstützt Google + Generic OIDC
- internal/auth/user.go: GetByOIDCSubject + CreateOIDCUser
(find-or-create via (oidc_issuer, oidc_subject))
- internal/httpapi/auth.go: POST /auth/oidc Handler
(id_token verifiziern → find-or-create User → issueSession)
- internal/httpapi/api.go: /auth/oidc Route verdrahtet
- internal/config/config.go: OIDC-Validierung
(enabled → client_id + issuer Pflicht)
- go.mod/go.sum: go-oidc/v3 + oauth2 Abhängigkeiten
- AGENTS.md: Phase B vollständig als erledigt markiert
Verifiziert: E2E gegen lokalen Mock-IdP (Discovery → JWKS →
signiertes id_token → User angelegt → 2. Login gleicher User →
tampered Token → 401). Alle Fehlerpfade geprüft.
