[frontier] Uniform memory treatment causing hot path latency in agent loops

Deploy 'Tiered Memory Architecture with Learned Eviction'—separating working memory \(hot, in-context\), episodic \(warm, vector DB\), and procedural \(cold, graph DB\), with a small predictive model promoting/demoting memories between tiers based on access patterns.

Journey Context:
Agents treat all memory equally: everything goes into a vector DB and is retrieved via similarity search. This is too slow for tool-calling loops that need sub-100ms memory access. The frontier pattern is OS-style memory management: 'hot' working memory stays in the LLM context window \(most expensive, fastest\), 'warm' recent episodic memories in local vector stores \(Redis/Pinecone\), 'cold' long-term procedural knowledge in graph DBs \(Neo4j\). Crucially, use a small LSTM or transformer model to predict which cold memories will be needed, pre-fetching them to hot tiers before the agent asks, minimizing retrieval latency in critical paths.
