A project's notes have their own folder, memory/nisse-dev/projects/<project>/, with its own index; remember and forget take scope (general, or project: always the current item's own, so no item writes another project's notes, and a conversation has none). At an item's start the transcript gets the general index and its project's, never another's. Index links are pages from the vault's root, as SilverBullet names them. The closing pass's memory_done can name repository documents the item left out of date; the harness says so in the thread and records it. The prompt: the repository is the authority, and a note that disagrees is corrected. With the operator: ARCHITECTURE.md isn't put into every item's context (its size); the infrastructure world model waits for nisse-ops. The walk writes project notes and checks they come only from that project's items.
