McpExtension built its middleware chain entirely internally, so a consumer had no
way to add rate limiting, audit logging or tracing to /mcp — routine on every other
Flash route. McpConfig.middleware(...) appends to the chain after the transport
guards and after whatever McpSecurity resolved to, so it composes with OAuth2
protection instead of replacing it, and never satisfies REQUIRED.
Docs: flash-ext-auth-core and flash-ext-auth-oidc both get a docs/ directory —
oidc had none at all, and its module README documented types that no longer exist.
Includes a migration table from flash-ext-oidc.
AuthMiddleware.install(ctx, config, source) now owns the annotation processor and
the flash.auth.policy key, so a second credential source gets annotation-driven
authorization without copying the wiring. The key is public: an extension that
contributes middleware can order itself around authentication.
OidcSession becomes Session in auth-core, carrying claims, an expiry and an opaque
attribute map. OpenID Connect keeps its access, id and refresh tokens in that map
under its own keys, so renewal stays its business and core has no OAuth2 vocabulary
in it. isAccessTokenExpired() becomes isExpired(), with the 30s eager-renewal
window it always had and now a test for it.
flash-ext-oidc is renamed flash-ext-auth-oidc, matching cache-core/cache-caffeine
and data-core/data-hibernate.
