- Replace testRoot template assertion with 'health endpoint returns 200 with status ok'
- Compose only configureRouting() in testApplication — NOT Application.module()
- This keeps the test independent of Database.migrate / running Postgres (D-11 test invariant)
- Install ContentNegotiation { json() } inside application { } — production module() does it,
but the test composes routing directly and must install the plugin itself
- All imports explicit (D-11 allWarningsAsErrors); no wildcards
- Body checked via substring for "status" + "ok" — robust to JSON field ordering
Note: ./gradlew :server:test runtime verification deferred to Plan 07 (integration build)
since build-logic/recipe.jvm.server plugin is being authored in parallel Plan 02 worktree.
