Report #81948
[frontier] Agent context window overflows causing loss of critical early-conversation instructions or user preferences
Implement three-tier hierarchical memory: working buffer, episodic vector store, and semantic summary with importance-weighted eviction policies
Journey Context:
Sliding windows drop important old tokens indiscriminately. Hierarchical systems treat context as a memory hierarchy: an OS-managed virtual context that pages data between fast \(context window\) and slow \(vector DB\) storage. Importance scores determine what gets evicted to disk versus kept in context, preserving critical instructions while maintaining conversational coherence.
