forked from wrenn/wrenn
Replaces the hardcoded CP_HOST_AGENT_ADDR single-agent setup with a DB-driven registration system supporting multiple host agents (BYOC). Key changes: - Host agents register via one-time token, receive a 7-day JWT + 60-day refresh token; heartbeat loop auto-refreshes on 401/403 and pauses all sandboxes if refresh fails - HostClientPool: lazy Connect RPC client cache keyed by host ID, replacing the single static agent client throughout the API and service layers - RoundRobinScheduler: picks an online host for each new sandbox via ListActiveHosts; extensible for future scheduling strategies - HostMonitor (replaces Reconciler): passive heartbeat staleness check marks hosts unreachable and sandboxes missing after 90s; active reconciliation per online host restores missing-but-alive sandboxes and stops orphans - Graceful host delete: returns 409 with affected sandbox list without ?force=true; force-delete destroys sandboxes then evicts pool client - Snapshot delete broadcasts to all online hosts (templates have no host_id) - sandbox.Manager.PauseAll: pauses all running VMs on CP connectivity loss - New migration: host_refresh_tokens table with token rotation (issue-then- revoke ordering to prevent lockout on mid-rotation crash) - New sandbox status 'missing' (reversible, unlike 'stopped') and host status 'unreachable'; both reflected in OpenAPI spec - Fix: refresh token auth failure now returns 401 (was 400 via generic 'invalid' substring match in serviceErrToHTTP)
