}Read a runner pool's work-queue stats
Returns the backlog a fleet operator scales and alerts on for one explicit RunnerPool: depth (advertised Runs this pool may claim that no Runner is holding), unpinned_depth (the share of that depth pinned to no pool and therefore claimable by any, D170 — so depths do not sum across pools), claimed_unacked (claimed by a Runner and not yet settled), oldest_queued_at (the earliest advertisement across both, null when the queue is empty), and runners_recently_seen (Runners in this pool with unexpired presence — Checkfu Runners announce rather than poll, and presence expires after a 30-second TTL). Subtract oldest_queued_at from measured_at for the age; nothing is precomputed against a hidden clock. Every number is a read-only projection over scheduling state — reading it never claims, holds, or expires work, and a stale read costs a scaling decision, never a Run. An unknown pool, or one in another workspace, is validation.not_found.
Checkfu support posture: preview; rollout_fenced. Required evidence journey: managed-runner. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
