Report #13706

[architecture] Agent runs out of context window or loses early conversation details

Implement a tiered memory architecture: use the context window as working memory for immediate reasoning, and a vector store as long-term memory. Evict older context by summarizing it and saving the summary to the vector store.

Journey Context:
Agents often try to stuff the context window or rely purely on RAG. Pure context limits scale and is expensive; pure RAG loses the sequential reasoning flow required for multi-step tasks. The tradeoff is latency vs capacity. Summarization/eviction to a vector store bridges this, keeping the active context small while preserving facts.
