// Bring-your-own-compute — Machines view-model.
//
// The data-contract types (MachineView / MetricSample / MachinesResponse /
// MachineMetricsSeriesResponse / MachineKind / MachineState) are the
// orchestrator-owned SHARED DATA CONTRACT that M10 ships in `@opengeni/sdk`
// (hand-written mirrors of `@opengeni/contracts`, pinned by contract-parity).
// M9 RE-EXPORTS them here so the dashboard UI imports a single, stable name and
// never drifts from the API — exactly as the contract intends.
//
// (During concurrent M9/M10 development this module briefly carried a local
// view-model with the same field names; once M10 landed the SDK types we
// reconciled to re-export them — the field names were identical by design.)
//
// Endpoints these model (M10 owns the SDK client methods):
//   GET /v1/workspaces/:ws/machines                        -> MachinesResponse
//   GET /v1/workspaces/:ws/machines/:enrollmentId/metrics/series?window=1h
//                                                          -> { samples: MetricSample[] }
