github-runner-fleet
Stand up, verify and repair a fleet of self-hosted GitHub Actions runners on one Windows host. Load when CI jobs sit queued while gh api .../actions/runners shows an online runner, when adding parallel capacity, when a workflow cannot get a runner, or before deleting any runner registration. Encodes the four failure modes measured 2026-08-12 — three of which each cost a failed attempt — plus the ghost-registration trap that makes a dead runner look like capacity.
