  # FAILOVER (Linux): each Linux enterprise job resolves its pool through the

  # pick the hosted enterprise pools below. Setting the variable to
  # 'selfhosted' (repo Settings → Actions → Variables; writer-manageable
  # repository state — not PR-editable, no merge required) retargets all
  # three onto the in-house
  # vm-backup pool and re-running the failed jobs is the entire switch —
  # see .agents/notes/implemented/process/2026-07-26-ci-failover-runbook.md. The
  # in-house pool's readiness is re-proven on every master push by the
  # serial-linux-selfhosted standby lane in ci-master.yml. The Windows failover
  # switch is the separate DSH_CI_FAILOVER_WINDOWS variable on the windows-native
  # job below.
