Report #41537

[architecture] Old memories retrieved via RAG polluting the context window and confusing the LLM with contradictory facts

Implement a memory curation step that applies temporal decay and filters out or overwrites semantically similar but older memories before injecting them into the context window.

Journey Context:
Agents often treat vector search as a simple top-K retrieval. But if a user changes their mind \(e.g., 'I actually prefer Python over JS'\), top-K might retrieve both the old and new preference. The LLM then gets confused or tries to average them. You need a curation step: either overwrite exact entity matches or apply temporal decay so newer facts outrank older ones, preventing stale context from polluting the current prompt.
