Compose Contract Audit

Audit one Docker Compose file and resolve its internal references. Reports two services publishing the same host port, where only one can bind; a named volume or network mounted and never declared; a dependency on a service this file does not define; a depends_on with no condition, so Compose waits for the container to start rather than for the service to be ready; and a wait for a service with no healthcheck, which can never be satisfied.
