// ── JobStatus mapping ───────────────────────────────────────────────────────

// JobStatusFromString maps the apiserver's job status string to a URM JobStatus.
//
// The input is the output of apiserver models.JobStateStr() — one of:
//
//	PEND, PSUSP, RUN, USUSP, SSUSP, RUNKWN, EXIT, DONE, UNKWN, ERR, TRANSIENT

// ── QueueStatus mapping ─────────────────────────────────────────────────────

// QueueStatusFromString maps the apiserver's composite queue status string
// (e.g. "open:active", "closed:inactive_adm") to a URM status:
//
//	active   — queue is open and accepting jobs
//	inactive — queue is administratively or window-closed
//	draining — open but has an inactive-time window active (will close)
//	unknown  — unrecognised format

// ── NodeStatus mapping ─────────────────────────────────────────────────────

// NodeStatusFromString maps the apiserver's host status string (output of
// models.HostStateStr()) to a URM node status:
//
//	idle    — OK, accepting work
//	busy    — running jobs
//	down    — CLOSED, CLOSED_BY_ADMIN
//	drain   — LOCKU, LOCKW (not accepting new work, existing jobs finish)
//	unknown — UNAVAIL or unrecognised
