Report #6072

[architecture] Agent retrieves outdated code or deprecated APIs as valid answers

Attach a strict ISO timestamp metadata field to all memories. Use hybrid search that combines vector similarity with a time-decay function or explicit recency filters during retrieval.

Journey Context:
Embeddings have no concept of time. A 2021 document on a library looks identical to a 2024 document in vector space. Without temporal metadata, the agent confidently uses deprecated logic. The tradeoff is that strict recency filters might exclude older but still-valid foundational knowledge, so a decay function is usually preferred over hard cutoffs.
