📝 WalkthroughWalkthroughOAuth configuration now separates system-loadable fields from engine-only OIDC fields. Runtime conversion seeds OIDC defaults and discovery metadata reads configured values. Tests and application setup now use the system OAuth configuration type. ChangesConfigurable OAuth and OIDC discovery
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR changes how OIDC discovery metadata and engine-only OAuth allow-lists are configured and advertised. Without the required documentation, engine integrators and API users may not know how to configure or interpret these behaviors, so the PR is not merge-ready until the documentation is added or explicitly accepted. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Restore configured core OAuth discovery coverage.
This test only verifies engine-only scopes, claims, and subject types. The removed tests covered configured response types, grant types, and token endpoint authentication methods. Add non-default values to config.OAuthConfig, derive the runtime config, and assert ResponseTypesSupported, GrantTypesSupported, and TokenEndpointAuthMethodsSupported.
As per coding guidelines, “Write tests for new features and bug fixes, targeting at least 80% coverage.”

mainPurpose
Introduces the plumbing for #5063: expose the OIDC discovery metadata (supported scopes, claims, subject types, and the default scope→claims mapping) as engine-only configuration. Deployments embedding ThunderID via
thunderidenginecan now override what the well-known endpoint advertises without touchingdeployment.yaml/default.json.Approach
OAuthConfigat the yaml boundary.internal/system/confignow has its ownOAuthConfigthat mirrors every yaml/json-loaded field ofengineconfig.OAuthConfigand nothing else. AToEngineConfig()converter copies fields into anengineconfig.OAuthConfigvalue. This structurally preventsdeployment.yaml/default.jsonfrom setting the new engine-only fields, because they do not exist on the yaml-loaded struct.engineconfig.OAuthConfig:AllowedScopes,AllowedClaims,DefaultScopeClaimsMapping,AllowedSubjectTypes. Named to match the existingAllowedGrantTypes/AllowedResponseTypes/AllowedAuthMethodsfields already on the struct. Engine integrators populate them via the existingWithOAuthConfig(...)option, no new engine options.oauthconfig.FromServerRuntime()callsToEngineConfig()and seeds the four fields (plusAllowedGrantTypes/AllowedResponseTypes/AllowedAuthMethodswhen empty) with the built-in defaults derived fromconstants.StandardOIDCScopes,providers.SupportedGrantTypes, etc. This keeps stock Thunder behavior byte-identical while giving engine embedders full control.getAllowed*getters (and the twogetAllowedScopes/getAllowedSubjectTypes) now return the configured slices directly. All fallback logic moved intoapplyOIDCDefaults.constants.GetSupportedResponseTypes/GetSupportedGrantTypes/GetSupportedTokenEndpointAuthMethods/GetSupportedSubjectTypeshelpers along with their tests. Callers underapplication/tools.goand the discovery service read the config directly. This also breaks the previousconstants→oauthconfigimport cycle that appeared onceoauthconfigneeded to reach intoconstants.StandardOIDCScopes.Related Issues
