[architecture] Agent keeps resurrecting outdated assumptions from old sessions into new conversations

Split durable memory into semantic \(facts\), episodic \(past tasks\), and procedural \(tool-use patterns\). Refresh semantic facts before retrieval, apply time-decay weights to episodic memory, and only persist deltas that were explicitly validated.

Journey Context:
Dumping every chat into a vector store makes old, wrong, or context-dependent statements resurface forever. The fix is to classify what kind of memory each item is. Semantic memory needs grounding and periodic reconciliation; episodic memory should fade unless marked high-impact; procedural memory should be stored as validated traces. Without this taxonomy, retrieval rankers are forced to treat a stale workaround the same as a current API contract.
