 Use `/agent auto|coder|researcher` to control routing. `/learning status [profile]`, `/learning metrics [profile]`, `/learning evidence <id>`, `/learning explain <id>`, and `/learning rollback <id>` expose lifecycle state and proof. Shadow replay accepts paired frozen results through the authenticated API and never executes replay commands. Project indexing remains separate knowledge ingestion.
 
+Inferred facts and preferences remain candidates until repeated independent evidence supports them. Explicit owner claims activate immediately. Typed global, profile, project, and task scopes resolve deterministically; `/memory why <id>` explains a claim and `/memory forget <id>` removes it together with solely dependent learned behavior.

 ### Memory storage
 
 OpenKyrozen v2 uses **SQLite as the source of truth** (`~/.kyrozen/v2/openkyrozen.sqlite3`) and ChromaDB as a rebuildable semantic index. Memories have a kind, scope, confidence, source events, and lifecycle status. Workspaces and sessions are isolated, raw observations are marked as data, and `/forget` removes records by durable ID. If ChromaDB is unavailable, SQLite keeps durable keyword retrieval.
