Definition
The systematic tracking and lifecycle management of source document iterations within a RAG pipeline to ensure vector embeddings and metadata remain synchronized with the ground-truth data. It prevents 'stale retrieval' by managing the replacement, expiration, or update of specific document chunks in the vector database.
Focuses on the temporal state of indexed data in a vector store rather than software source control like Git.
"A building's blueprints where every revision is stamped with a date; builders (the LLM) must only use the version with the most recent stamp to avoid structural errors."
