Product, order and inventory services behind Spring Cloud Gateway (WebMVC), configuration from a Config Server, discovery with Eureka, a Resilience4j circuit breaker on order -> inventory and Brave tracing. Run as six plain jars; output/ holds real transcripts (config, registry, requests, trace propagation, circuit breaker, startup race and the load-balanced RestClient.Builder trap). Dockerfile and docker-compose.yml are included but were not run. Co-Authored-By: Claude Sonnet 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01HhW8LD8r3EigoBaCGrQZx5
