+(ns vibe.integration.coverage
+  "Entry point that runs the vibe server under Cloverage instrumentation so the
+   black-box integration tests produce a line-coverage report.
+
+   Cloverage normally instruments the source and then runs a test suite in-process.
+   Here the 'suite' is the outside world: the runner starts the real server and blocks
+   until the JVM gets SIGTERM (`docker compose stop`), then Cloverage writes its reports.
+
+   Deliberately does not require any vibe.* source namespace at load time: those must
+   be loaded by Cloverage (instrumented), not by us."
