Knowledge-and-Memory-Management Project Finalizes Core Docs for Directions 1-3

The Knowledge-and-Memory-Management project has officially completed documentation for its first three core development tracks. Direction 1 standardizes the data ingestion pipeline, requiring all inputs to pass through a mandatory parse-validate-index sequence via a new KnowledgeIngestor interface. Direction 2 finalizes the memory storage layer, defining separate volatile and persistent backing stores with explicit eviction policies and required configuration variables. Direction 3 introduces the SynthesisPlan object and a unified retrieve_synthesis API, replacing fragmented retrieval methods with a single consistent entry point. Together, these finalized specifications aim to reduce ambiguity and provide clearer implementation guidance for developers building long-lived agent systems or knowledge bases.
