 Repo Assist uses one schema-validated `notes.json` file to carry concise, actionable state across runs. It records backlog cursors, unresolved issue interactions, fix attempts, the latest engineering checks, maintainer-completed monthly actions, and a short priority queue. The workflow verifies remembered facts against current repository state before acting, replaces superseded entries, and removes stale records rather than accumulating a run-by-run activity log.
 
-Repositories upgrading from the earlier multi-file memory format are migrated automatically: legacy memory files are removed the next time Repo Assist saves `notes.json`.
+Repo Assist stores this file on the dedicated `memory/repo-assist-memory` branch. Repositories upgrading from an earlier Repo Assist version start with fresh memory on this branch; legacy memory branches are not migrated or modified.
