Tri-Tier Architecture of Permanence
Structural memory, episodic memory, and working memory are physically isolated — and a policy tier sits above them to carry transferable experience without contamination.
Engineering substance
Foundation models forget on contact and confuse the rules with the events. Chonglou physically isolates three memory layers and adds a policy tier that absorbs reusable action experience — promoting memory architecture into experience architecture.
Three tiers · one policy layer
Each layer has a single responsibility. They never bleed into each other; the policy layer governs what may transfer.
- 01Structural memory — invariant laws and stable knowledge
- 02Episodic memory — one-time events and concrete experience
- 03Working memory — transient context inside the current task
- 04Policy tier — transferable action experience, guarded against hallucinated transfer
Eastern Narrative
Chonglou — a tri-tiered pavilion: each storey keeps to itself, never intrudes on the next.
Why It Matters
Cures the foundation-model disease of forgetting on sight, mixing memories, and losing long-horizon consistency.
