# RAG: vector store + structured store
# 2026-05-14: pinned to 1.5.9 to match the local .venv version that builds
# rag/vectors. Schema drift between chroma versions caused KeyError('_type')
# in earlier deploys, wiping the index and forcing a 45-min re-ingest.
# Bump both local AND this pin together if upgrading.
