memory architecture

Article references 'memory layer' as source for context injection and mentions 'compacted memory summary' as MVC component. Memory architecture is operational substrate for context engineering.

Distinguishes between learned context (core+archival) and transcript history (recall) as separate persistence layers

Proposes three-layer memory system for knowledge accumulation across sessions—directly addresses intelligence compounding rather than session resets.

Engram system demonstrates stratified memory design (static knowledge vs dynamic reasoning) as a context management pattern

Introduces episodic/semantic/procedural memory taxonomy for LLM systems, providing structured framework for thinking about knowledge persistence

Scratchpad pattern (agent writes and reads back notes) is a specific memory architecture pattern within longer agent workflows.

Session management is foundational memory architecture—distinguishing between ephemeral (within-session) and persistent (cross-session) context.

Tutorial explicitly implements short-term and long-term memory as separate systems, demonstrating the architectural pattern of dual-layer memory design.

Discusses 'how memory works in multi-agent systems' as foundational to agent coordination, implying distributed memory/context challenges.
