- oidc/oidcState.ts (pure, +3 tests): dynamic-registration cache (by issuer +
redirectUri, corrupt-tolerant) and parseOidcCallbackParams (success/error/invalid).
- oidc/oidcLoginUtil.ts: getOrRegisterClientId (cache + registerOidcClient) and
startOidcLogin (discoverAndValidateOIDCIssuerWellKnown -> generateOidcAuthorization
Url -> redirect; invalidates the cache on failure). redirectUri is the
deterministic getOidcCallbackUrl(), and the SDK returns clientId/issuer on
callback, so no hand-rolled transient state is needed.
- login/OidcLogin.tsx: native-OIDC button mirroring SSOLogin + TokenLogin async/error.
- login/Login.tsx: issuer-gated — when discovery advertises an issuer, render
OidcLogin and suppress password/legacy-SSO; non-OIDC servers unchanged.
