- ci: reject a manual dispatch with tag "latest"; concurrency group per tag - Dockerfile: declare GIT_COMMIT after the module download layer - Makefile: docker-build targets linux/amd64 by default - patch.go: no shared package-level pointers; main.go: no init() - tests: assert that merge replaces managed listener content - docs: flows.md startup section matches main.go; review saved to docs/reviews Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
