A description of a seven-layer cognitive architecture for AI agents — memory, beliefs, feelings, reflexes, immunity, predictions, and narrative, bound by a nightly consolidation pass. The system has been running in production for about a year; live counts from the database are in the post.
Opens with a meta moment: while drafting the section on the immune layer, one of the system's own hooks fired and blocked the author mid-paragraph — the architecture working on its writer in real time.
The post describes the shape of the architecture without publishing the internals — schemas, update math, trigger grammar, and phase pipeline are held back. It is a description of what has been built, not a research proposal. Interested to see how this composed-layers approach reads against the current memory-layer-focused work from Mem0, Letta, and others.
