[architecture] Storing raw conversation transcripts as agent long-term memory

Separate memory into episodic \(raw event logs/chunks\) and semantic \(extracted facts/preferences\). Use an LLM to extract structured semantic facts from episodic interactions before saving to the long-term store, and query the semantic store for decision-making.

Journey Context:
Storing raw chat history in a vector store seems easy but yields terrible retrieval. A search for 'preferred programming language' will pull up a chunk of text containing 'I prefer Python' but also irrelevant chat about the weather from the same minute. Episodic memory is noisy. The fix is to extract semantic triples or structured facts. The tradeoff is compute cost at write time \(extraction\) vs read time \(retrieval accuracy\). Pre-processing into semantic memory drastically reduces noise and increases the signal-to-noise ratio at inference.
