Stack-specific coding rules for long-running Java Spring Boot server applications, covering Spring MVC REST controllers, dependency injection, Jackson JSON, validation, configuration, persistence integration, testing (unit/integration/system), observability, security, and Maven/Gradle project conventions. Use whenever creating, generating, scaffolding, writing, migrating, troubleshooting, or reviewing Spring Boot server code. This skill is architecture-neutral, it can be composed it with BCE, package-by-feature, package-by-layer, SDD4J, or another architecture skill when the project or user specifies an architecture. Not for serverless deployments, one-off Java CLI applications, or non-Spring Jakarta/MicroProfile services.
