[I] langchain4j-embeddingstore: RAG augmentor auto-detection ignores synthetic EmbeddingStore/EmbeddingModel beans [camel-quarkus]

["jiriOndrusek-agent (via GitHub)" <gi...@apache.org>]

jiriOndrusek-agent opened a new issue, #9225:
URL: https://github.com/apache/camel-quarkus/issues/9225

   The docs promise a default `RetrievalAugmentor` from the `@Default` `EmbeddingStore` and `EmbeddingModel` beans. With a Quarkus LangChain4j store (e.g. `quarkus-langchain4j-pgvector`) none is produced: injecting `RetrievalAugmentor` fails with `Unsatisfied dependency for type dev.langchain4j.rag.RetrievalAugmentor`, and `@RegisterAiService` silently runs without RAG.
   
   Cause: `Langchain4jEmbeddingstoreRagProcessor.BeanCensus` counts beans from `BeanDiscoveryFinishedBuildItem`, which by its javadoc excludes synthetic beans. All Quarkus LangChain4j store and model beans are synthetic. The existing IT passes only because its store is an application-produced `InMemoryEmbeddingStore`.
   
   Proposed fix: also count Quarkus LangChain4j's `EmbeddingStoreBuildItem` (stores) and `EmbeddingModelProviderCandidateBuildItem` / `InProcessEmbeddingBuildItem` (models). `SynthesisFinishedBuildItem` is not an option, as the step itself produces a synthetic bean.
   
   Reproducer: the `langchain4j-ingest-rag` example (PR to follow), with `DocumentsAugmentor` removed. camel-quarkus main, quarkus-langchain4j 1.13.3.
