+"""Warm pool subsystem for `agent_session_endpoints` (LIT-2890).
+
+Pre-provisions a small pool of EC2 (or other provider) VMs per team so
+``POST /v2/sessions`` can attach a fully-booted VM in <3s instead of the
+30-90s cold-boot path.
+
+Public surface:
+- ``WarmPoolManager`` — async maintenance loop (start it on proxy boot)
+- ``attach_warm_vm`` — race-safe attach + hydrate, called from session create
+- ``HydratePayload`` — wire format the daemon receives
