The Runbook That Had Never Worked
An automated restart action passed its guardrail suite for weeks. It had never successfully restarted anything, on any host, because ssh does not preserve argument boundaries.

Checks That Lied
Three times a green signal meant nothing: a backup that restored an empty file, a failover test that proved the opposite of what it claimed, and a runbook that had never once worked.

The Backup That Restored an Empty File
A nightly Kubernetes backup reported success for weeks. Every restore produced a zero-byte cluster token, because tar archived a symlink instead of following it.
