 During `keploy test`, Enterprise rewrites the Compose file and injects its own shared `/tmp` volume for the dedup control/data sockets. The base sample Compose file does not need a host `/tmp` bind mount.
+Re-run `docker compose build` whenever the jar, JaCoCo agent, or Dockerfile changes so replay uses the current image.
+
+The CI pipeline also validates additional production-style Docker layouts for the same app, including exploded classpath, restricted runtime, and distroless packaging.
