Support matrix

Feature	Status
@Component, @Service, @Repository, @Controller, @RestController (direct)	Supported
Constructor injection, exactly one non-private constructor	Supported
Concrete and non-generic interface resolution	Supported
Singleton scope (default, or @Scope("singleton"))	Supported
Missing / ambiguous / eager constructor cycle	Supported (SG001 / SG007 / SG003)
Declared runtime boundaries	Supported (report only); typos, stale and shadowed declarations reported as SG009
Spring Data repository interfaces (extend Repository, not @NoRepositoryBean)	Recognized, reported as "created at runtime", never counted as validated
@Value constructor parameters	Recognized as property values, not bean dependencies
Other scopes	SG004, component excluded
Zero or multiple constructors	SG005, component excluded
Generics, collections, Optional, Provider, @Lazy	SG006, dependency not validated
@Qualifier("name") on a constructor parameter	Supported since 0.1.0-rc.3. A candidate matches by its class-level @Qualifier value (also inherited from a superclass) or by its bean name, as in Spring
@Qualifier without a value; @Named or custom qualifier annotations on a parameter	SG008, dependency not validated
@Qualifier when a candidate is named by @Named / @ManagedBean or has a custom qualifier	SG008, dependency not validated
Several candidates match the same @Qualifier	SG006: Spring then chooses by bean name, which is not modelled
@Primary	Supported since 0.1.0-rc.3: a unique @Primary candidate is validated; several are SG007. Also via meta-annotation
@Fallback (Spring 6.2+)	Supported since 0.1.0-rc.3: without @Primary, a unique non-@Fallback candidate is validated
A component that requests its own type (decorator pattern)	Supported since 0.1.0-rc.3: it is not its own candidate unless nothing else matches, as in Spring
@Priority among several remaining candidates	SG006, dependency not validated
Several candidates, parameter name equals one bean name	SG006: Spring's name fallback needs -parameters, which the processor cannot see
Lombok-generated constructors (@RequiredArgsConstructor, @AllArgsConstructor)	Supported, any processor order (Maven checked; see maven-lombok.md)
Maven annotationProcessorPaths	Supported (plain Maven 3.8.8 checked)
@Profile / @Conditional* components (also via meta-annotation)	Kept in the graph and their own dependencies are checked, but never used to resolve a dependency. A dependency with conditional candidates is SG006 unless its type is declared a runtime boundary.
@Configuration / @Bean	Not interpreted; listed as excluded in the report
Composed stereotypes, field/method injection, conditions, profiles, multi-module, Kotlin	Not supported

In advisory mode every diagnostic is a warning; in strict mode every diagnostic is an error.
