Generated from bd help --doc heartbeat. Refresh the lease on an issue you currently hold in_progress. A claim carries a lease that expires after a TTL. A worker keeps its claim alive by heartbeating faster than the TTL; once it stops (because it died), the lease goes stale and ‘bd reclaim’ reverts the issue to ready so another worker can pick it up. Heartbeat pushes lease_expires_at forward and stamps heartbeat_at = now. Only the current owner may heartbeat. If the lease has already been reclaimed or the issue closed, heartbeat fails so the worker learns to stop. Heartbeat writes a Dolt commit, so heartbeat well below the TTL but not so fast it bloats history — cadence should be a small fraction of the TTL, not per-op.
