 Status: in_progress
 
 DoD:
-- project has an idempotent PostgreSQL demo seed for live UI screens
-- demo seed fills workspaces, memberships, invitations, operations, agents, keys and usage
-- seed is controlled by env and does not live in migrations
-- docs explain how to enable and use demo data
+- `feat/agent-lifecycle-polish`
+- agents support explicit `publish`, `unpublish`, and `archive` lifecycle transitions
+- agents page reflects real backend lifecycle states without legacy `active/inactive` mapping
+- agent cards and editor can move between draft/published/archived without destructive hacks
 
 ## Next
