Kill switch runbook
Triggers, the authorized roster, and the notice sent to people whose cases were held.
Give a named roster pre-authorized power to halt an automated system when harm indicators fire. The halt contains harm while the rule's owner corrects the rule and the people harmed are restored.

Where it acts
At Correction, one of the seven stages every consequential decision passes through. It halts the system when harm indicators fire, so harm stops spreading while the rule is fixed.
Steps
3 steps, in order. Check each one off as it is done; the records below show the work was done.
0 of 3 steps complete
What a team running this mechanism keeps, and what each record is for.
Triggers, the authorized roster, and the notice sent to people whose cases were held.
Each person harmed, what they are owed, and the date each was restored.
What fired the switch, what the rule's owner changed, and whether the trigger threshold moved.
Reuse-ready snippets

Policy requirement
Policy requirement (MEC-05 Kill switch for runaway automation) - Keep a pre-authorized halt path with a named roster, and protect anyone on it from retaliation for using it. - Publish halt triggers tied to harm indicators, each with a time-to-halt target. - Resume only after the rule's owner records a fix and a dated plan exists to restore the people harmed. Reference: https://ethotechnics.org/mechanisms/patterns/kill-switch
Product requirement
Product requirement (MEC-05) - Operators can fire the kill switch in one step from the monitoring view. - Each halt emits a receipt naming who fired it, the trigger, the cases held, and the restoration checklist.
Audit evidence checklist
Audit evidence checklist (MEC-05) [ ] The runbook names the authorized roster and the triggers. [ ] Drill logs show measured time to halt against the target. [ ] Each real halt links to the rule change that followed and a record of the people restored.
Postmortem trigger
Postmortem trigger (MEC-05) Trigger review when a time-to-halt target is missed, the kill switch is unavailable, or automation resumes with no recorded fix and no plan to restore the people harmed.
Example usage
One scenario with each part of the mechanism in place.
How it plays out
After a meter-data change, a utility's billing rule flags three times the usual number of homes for disconnection, and upheld disputes spike. The on-call operator halts disconnection notices in four minutes. The rule's owner corrects how the rule reads the new meter format. The 310 households already notified get a withdrawal letter and a fee refund. Then notices resume.
Anti-patterns
Each case passes on paper and fails in operation. The counterfactual shows what would have worked.
A halt path exists on paper but has never been fired, so the first real use finds missing permissions and stale contacts.
Counterfactual: The halt is drilled, and each drill records time to halt against the target.
Exception: A tabletop drill can stand in where a live halt would harm people, if the log records what it could not test.
Only one person can fire the halt, so at night or during their leave nobody can halt the system.
Counterfactual: A named roster can fire the halt at any hour, without sign-off and without retaliation.
Exception: A small team can run a primary and a secondary, if the roster shows who covers each hour.
Tools that size the risk this mechanism addresses.
Diagnostic
Walks a team through one workflow against six questions and returns an exposure score, the permissions nobody can justify, and whether its decisions can be undone. Start here when the system keeps no decision records yet; use the record conformance checker once it does.
