[architecture] Agent loses track of sequential instructions or recent tool outputs when using a vector database for all memory

Implement a tiered memory architecture: keep recent, high-salience interactions \(working memory\) in the context window, and use the vector store \(long-term memory\) only for archival retrieval. Flush working memory to long-term memory when context limits approach.

Journey Context:
Vector DBs destroy temporal ordering and co-occurrence context via chunking. Context windows preserve sequence but have hard limits. A single-tier memory architecture fails because either you lose sequence \(vector-only\) or you lose history \(context-only\). Tiered memory mimics human cognition, solving the recency/retrieval gap, but requires engineering an explicit flush/sync mechanism between the tiers.
