[architecture] Agent retrieves outdated facts that contradict current state

Implement time-decay weighting in vector retrieval \(e.g., exponential decay on embedding timestamps\) and periodic memory consolidation to merge stale facts into higher-level insights.

Journey Context:
Without decay, old states \(e.g., 'user lives in X'\) pollute new states \('user moved to Y'\). Vector similarity alone doesn't respect time. Hard TTLs are too rigid because they destroy long-term semantic knowledge. The right call is recency bias in retrieval scoring combined with background consolidation that distills old facts rather than just deleting them.
