• zenbrain_consolidateConsolidate memorycan change or delete data

  Run one consolidation pass: among the 100 most recent episodes, each one with an emotional weight above 0.5 becomes a semantic fact — once, however often the pass runs. Working-memory slots lose relevance with age, and slots whose relevance has dropped to 0.01 or below are removed; that is the only deletion, and nothing in long-term memory is deleted. Run it between sessions or after a batch of zenbrain_store calls, not on every turn; compare zenbrain_health before and after to see the effect.

• zenbrain_forgetForget a memorycan change or delete data

  Permanently delete a memory, addressed by the id and layer that zenbrain_recall returned for it, together with what consolidation linked to it; this cannot be undone. Forgetting an episode also deletes the fact zenbrain_consolidate made from it; forgetting such a fact also deletes every episode consolidated into it; both also delete the working-memory copies of that content. Forgetting a working-memory result deletes only that copy. alsoForgotten lists everything deleted besides the memory itself. A memory stored on its own and never consolidated keeps its long-term entry. Use it when the user…

• zenbrain_healthInspect memory stateread-only

  Report how full the memory layers are: working-memory slots in use, interactions held, episodes, facts and how many are due for review, procedures, core blocks. Read-only and cheap, safe to call at any time. It returns counts only; to read the memories themselves, use zenbrain_recall.

• zenbrain_storeStore a memory

  Write something into long-term memory so it survives this conversation. Routing is automatic by default, first match wins: `steps`, or wording such as "How to", "Steps:" or "workflow:", make a procedure; an emotional weight above 0.5 (detected, or set via `emotionalWeight`) an episode; a `confidence` above 0.9 a pinned core memory; anything else a semantic fact. Set `type` only when you want to override that. Every call adds a new memory, except that storing the same core memory again updates it; the content is also kept in working memory (the most recent seven) while the server runs, so once …
