Agent Canvas

Agent Canvas is the shared Alera surface for an agent run. The runtime host owns persistence, revisions, decisions, retention, and events. Use the alera canvas command instead of writing to an application socket or modifying runtime SQLite directly.

Identity

Run inside an Alera terminal so ALERA_WORKSPACE_ID and ALERA_TERMINAL_SESSION_ID identify the one canvas owned by that terminal. ALERA_TAB_ID and ALERA_AGENT_TYPE are used when available. A canvas is scoped by workspace and terminal session.
