Show HN: Find stale, orphaned, deleted-but-retrievable RAG vectors
Summary
Show HN post describes rag-staleness-check, a read-only tool to check stale/orphan/duplicates in vector indexes (pgvector, Qdrant, Chroma) for RAG pipelines; highlights how it identifies retrievable-after-delete, and enforces no-write behavior. Useful for data quality and governance in vector-based retrieval systems.
