- structured-logger.ts header bullet "External system integration via hooks with circuit breaker" -> updated to describe current fire-and-forget hook semantics + hookFailures metric counter. - retry-utils.ts retryConfigs.rsocket comment referenced the prometheus-metrics -> circuit-breaker.ts circular import chain. circuit-breaker.ts is gone; trimmed the parenthetical to keep just the core reasoning (avoid ESM init-order issues via prometheus-metrics). No code change. Build clean, 35/35 suites, 809/809 tests pass.
