We expanded the observability surface around RAG infrastructure. The codebase includes health and metrics modules so runtime state can be inspected instead of inferred.
This does not claim production uptime or performance. It establishes the plumbing required to measure and debug those properties.
Ingestion guardrails were added to make document handling and chunk quality more explicit before retrieval uses the content.
A feedback store was added so retrieval and answer behavior can be improved from recorded outcomes instead of anecdotes.
A circuit breaker path was added so repeated retrieval or generation failures can be surfaced instead of retried blindly.
