 Turning a policy Off does not recreate lobbies it removed or remove lobbies it created. Once operations settle, use Collections to restore a fixed lineup through the normal capacity and empty-server gates.
 
+## Delete a policy
+
+Choose **Delete policy** and confirm to remove its settings, decisions, and measurements. Existing lobbies, saved keys, and Provisioning history are kept. Deleting a live policy releases ownership without changing the lineup, and a new policy can reuse the same scope.
+
+Deletion requires the current policy revision and no unsettled autoscaling operation. If work is outstanding, turn the policy Off and wait for its operation to settle before deleting. Delivered or uncertain host commands retain their policy and admission evidence until reconciliation finishes.

 `GET /api/autoscaling` returns policies, current evidence, recent decisions, measurements, and global pause state. Viewers may read it; mutations require an operator or administrator, using the existing authentication and origin checks.
 
-`POST /api/autoscaling` accepts `preview`, `save`, or `global-pause`. Preview/save requests contain `settings`, plus `id` and `revision` when editing. Use `mapSlug: '*'` for every map in the selected game; existing map-specific requests are unchanged. Scope cannot change when editing. Save also requires the preview `token`. Global pause uses a boolean `paused` field. Agent removal claims use a separate host-authenticated endpoint and are bound to the exact command, host, instance generation, policy revision, and expiry.

 Shared contracts live in `src/lib/autoscaling.ts`; the evaluator, snapshots, persistence, ownership, and authorization live in `src/lib/server/autoscaling/`. Provisioning remains the only lifecycle executor. See the [approved implementation plan](lobby-autoscaling-plan.md) for the design and rollout criteria.
