1. Rejections are logged. chassis v0.2.0 refused without a log line, so since #149 an unknown REST caller got silent 401s. v0.7.1 writes `mcp auth rejected` (reason, remote, token fingerprint, path) and `mcp auth accepted` per authenticated request. Tested through buildMux. 2. Fallout: since chassis v0.7 (mcp-chassis#4) NewJWTValidator no longer fails on OIDC discovery; the issuer resolves lazily and a JWT gets 503-and-retry until it does. #83's boot retry loop therefore never retried, and its tests failed. buildJWTValidator now builds once and logs an issuer still unresolved at boot. Behaviour change: a misconfigured issuer no longer exits the process; JWTs get 503, the static bearer keeps working. internal/startupretry is now unused. 3. Metrics: authenticated REST requests were already labelled by route (the REST mux sets Pattern on the same *http.Request the middleware reads). Requests refused by auth never reached the REST mux and were labelled path="/". labelRESTPattern now sets the REST route's pattern before auth; unmatched paths keep "/", so the label set stays bounded.
