[architecture] Agent loses the chronological order of events when storing memories leading to broken procedural reasoning

Maintain an append-only event stream \(episodic memory\) for chronological sequences, separate from the semantic vector store \(semantic memory\).

Journey Context:
Chunking and embedding text into a vector store destroys temporal order. If an agent needs to recall the steps taken to debug a server, semantic similarity is useless; it needs the sequence. The tradeoff is storage overhead vs. temporal fidelity. By separating episodic memory \(a time-ordered log\) from semantic memory \(a vector store\), the agent can query the log for what happened and the vector store for what it means.
