Menu Band (direct-download build) queues each exported take in ~/Library/Application Support/MenuBand/cloud-queue and drains it to /api/menuband-takes: begin, presigned PUTs, commit. A take waits on disk while offline or signed out. A two-bell chime (D6 → A5) rings when a take reaches @handle, quieter than the saved-on-Desktop arpeggio. Settings has the on/off switch. Auth0 rotates refresh tokens, so two refreshes of one token sign a Mac out. Every refresher on a Mac (ac-login, Menu Band and shared ACSession.swift, Aesel, whistlegraph-mcp, daily-token) now renews under the ~/.ac-token.lock directory and re-reads inside it, keeping a token another process already renewed. shared/ac-token.mjs is the Node helper; new `ac-login refresh` renews without a browser. Each machine keeps its own sign-in; ~/.ac-token is never copied between machines. Co-Authored-By: Claude <noreply@anthropic.com> (cherry picked from commit 9849a69f66d7b36d9a5ab63dba8f5cb7e9f6156b)
