Report #82898

[architecture] Storing every interaction permanently makes the vector database too noisy for accurate retrieval

Implement memory decay using a composite retrieval score: \`score = recency \* relevance \* importance\`. Periodically evict or archive memories that fall below a minimum score threshold.

Journey Context:
Infinite accumulation is a common anti-pattern. As the DB grows, cosine similarity alone fails because old, irrelevant facts might perfectly match the query embedding semantically, drowning out recent critical context. Time-weighted RAG fixes this. The tradeoff is tuning decay rates and importance weights versus losing rarely accessed but critical facts \(which requires an importance score override to protect key memories\).
