  # FAILOVER: each Linux enterprise job resolves its pool through the
  # DSH_CI_FAILOVER repository variable. Unset (normal), the expressions
  # pick the hosted enterprise pools below. Setting the variable to
  # 'selfhosted' (repo Settings → Actions → Variables; admin-only, 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
