-//
-// Origin: core#11 — canvas detail-panel config + filesystem load

-// deleteFileViaEIC pays the full setup cost even when fired

-//     instanceID don't both build a tunnel — the loser drops its
-//     setup and uses the winner's.
-//   - Refcount on each entry; eviction blocked while refcount > 0.

-// cp_orphan_sweeper.go — SaaS-mode counterpart to orphan_sweeper.go.
-//
-// The Docker sweeper (StartOrphanSweeper) runs only when prov != nil
-// (single-tenant Docker mode); SaaS tenants run cpProv != nil and prov
-// == nil, so they get no sweep coverage from that path. This file fills
-// the gap for the deprovision split-write race documented in #2989:
-//
-//	1. handlers/workspace_crud.go:365 marks workspaces.status = 'removed'.
-//	2. workspace_crud.go:439 calls StopWorkspaceAuto → cpProv.Stop, which
-//	   issues DELETE /cp/workspaces/:id?instance_id=… to controlplane.
-//	3. If step 2 fails (CP transient 5xx, network blip, AWS hiccup), the
-//	   inline path returns a 500 to the canvas — but the DB row is already
-//	   at status='removed' with instance_id still populated. There's no
-//	   retry, and the EC2 lives forever.
-//
-// This sweeper closes that gap by re-issuing cpProv.Stop on every cycle
-// for any workspace at status='removed' with a non-NULL instance_id.
-// Stop is idempotent: AWS TerminateInstance on an already-terminated
-// instance is a no-op (per AWS docs), and CP's Deprovision handler
-// (controlplane/internal/handlers/workspace_provision.go:289) handles
-// the already-terminated and already-deleted-DNS cases via best-effort
-// guards. On Stop success, the sweeper clears instance_id so the next
-// cycle skips the row.
-//
-// Cadence + safety filters mirror the Docker sweeper:
-//   - 60s tick (OrphanSweepInterval)
-//   - 30s per-cycle deadline (orphanSweepDeadline)
-//   - LIMIT 100 per cycle so a sustained CP outage that backs up many
-//     orphans doesn't blow the request timeout; subsequent cycles drain.
-//
-// SSOT note: Stop's idempotency (no-op on empty instance_id, AWS
-// terminate on already-terminated) is the load-bearing invariant. Any
-// future change that adds non-idempotent side effects to cpProv.Stop
-// must also gate this sweeper, or it will re-execute those side effects
