[architecture] Old retrieved memories polluting current context window and overriding new instructions

Apply a relevance threshold and cross-encoder reranking before injecting memories into the prompt; never inject memories with higher confidence than the system prompt.

Journey Context:
Just dumping top-k vectors from a DB into the context introduces stale, contradictory, or low-signal info. The LLM then hallucinates or gets confused, prioritizing the injected text over its instructions. You need a strict curation step \(e.g., cross-encoder reranking, thresholding\) between retrieval and injection to ensure only high-signal, currently relevant memories make it into the working context.
