Simulate the attack with Atomic Red Team, then re-run the rule’s own converted query over the attack window and ask it directly whether it matched. not_triggered is the honest answer.

Idempotent deployment keyed on the Sigma UUID, so a renamed rule updates in place instead of spawning a duplicate. And a –dry-run that never lies about being deployed.

Don’t assume what a SIEM’s REST API can do. Write a prober that asks the live instance, and let the answer shape the architecture.
