A Spring self-check tests spring core ownership using the source-kit contracts.
Review before answering
- Spring ApplicationContext: construct and close an object graph
- Spring constructor injection: required dependencies stay visible
- Spring qualifiers: select a collaborator when types are ambiguous
- Spring bean scopes: singleton identity is not thread safety
- Spring ObjectProvider: deferred resolution without hiding ownership
- Spring lifecycle cleanup: close container-owned resources
- Spring application events: local delivery is not a durable queue
- Spring AOP proxies: self-invocation bypasses proxy advice

Common Mistakes
Distinguish a checked local fixture from a production guarantee. Container ownership, database atomicity and request authorization require separate evidence.
