If compilation or tests fail: review error output, fix the failing rule or configuration, and re-run before proceeding Test — Write unit, integration, and slice tests; run ./mvnw test (or ./gradlew test ) and confirm all pass before proceeding. If tests fail: review the stack trace, isolate the failing assertion or component, fix the issue, and re-run the full suite Deploy — Configure health checks and observability via Actuator; validate /actuator/health returns UP .
