Browse Source 
Three verified programs (JDK 25, Spring Security 7.1.1, Spring Boot 4.1.1 dependency
versions) backing the ankurm.com post: InheritableThreadLocal across thread models,
@Async on a virtual-thread SimpleAsyncTaskExecutor (DelegatingSecurityContextExecutor
vs ContextPropagatingTaskDecorator), and StructuredTaskScope.fork() propagation.
Captured console output and docs chapters included.
