We added circuit breaker support for RAG failure paths. Repeating the same failing operation can waste latency and hide the real issue.
The breaker is part of failure transparency. When the system cannot proceed reliably, it should stop or degrade explicitly rather than producing a confident answer from weak evidence.
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.
Prompt loading work made behavior dependencies easier to inspect instead of hiding important instructions inside ad hoc strings.
