[architecture] Agent retrieves irrelevant old memories and repeats stale decisions

Score memories by recency, importance, and relevance; decay low-signal entries and blend vector similarity with time-decayed weights.

Journey Context:
Pure vector retrieval returns semantically similar facts, but similarity is not the same as usefulness. A memory from six months ago can be close in embedding space to today's problem while being dangerously stale. Generative Agents showed that human-like memory retrieval combines recency, importance \(manually or automatically scored\), and relevance. Without decay and salience weighting, the store fills with noise and retrieval precision collapses. The cost is domain-specific tuning of decay constants and importance heuristics.
