The Rehearsal: Proving You Can Stop the Agent Before You Have To | Governed by Design #8

You filled in the Suspension Authority Ledger. A name, measurable triggers, an ordered notification chain. One question remains: is any of it true?

In this episode, Alex and Jaime take Edition 7's sixth primitive from declaration to evidence. A ledger that has never been exercised isn't a control, it's a hypothesis about a control. And the first real test of a hypothesis shouldn't be a live incident. You'll learn:

• Why every field of a ledger can be correct and the ledger can still fail on the day it matters
• The Rehearsal Loop, five timestamped stations: simulate, detect, escalate, execute, notify
• Why "Execute the suspension" is the station that finds expired credentials and missing permissions
• A worked run: 26 minutes, two findings, the unconfigured alert rule and the read-only authority holder
• How rehearsal findings feed the Gap Register (the sixth primitive strengthening the fifth)
• The Tested field in full form, Date · Authority holder · Observer, and why two names are two different assurances
• The 90-minute run-sheet: three roles, four pre-conditions, findings logged, not fixed
• What suspension does to in-flight work: draining vs hard stop, idempotency, downstream timeouts
• Why this plugs into the DORA resilience testing programme financial firms already run

This edition pays off Edition 7's closing promise: the Tested field. Not a seventh primitive, one field added to the sixth, the field that separates a ledger somebody wrote from a ledger somebody proved.

Key Insight: Documented capability and demonstrated capability diverge in exactly the moments that matter. A rehearsal moves every discovery to an afternoon you chose, instead of an incident you didn't. The first time you stop an agent shouldn't be the first time you try.
