Start with the record that can say attendance was missed
Choose one safely simulated or approved appointment fixture. Record its identity, the authority that can report attendance, the observation itself, and when it was made. Keep that record separate from a customer message, a fee decision, or an available slot. Those can be related, but none follows automatically from a label in a screen.
NIST's contingency-planning guide is used here only for the general discipline of owned recovery and exercises. It does not set an appointment policy or prove that a scheduling provider performed a recovery.
Retain one bounded recovery receipt
For the selected fixture, write down the recovery-policy reference, the capacity decision and owner, who owns customer contact, and how an ambiguous record is escalated. A capacity decision can be hold for review, release, or another named action under an approved policy; do not infer it from the attendance report.
The local fixture rejects an exercise that leaves the important boundary unnamed:
node --test sites/howtox.com/evidence/P146/no-show-recovery-receipt.test.mjs
It does not observe a person, create or release a real booking slot, deliver a message, apply a fee, or call a provider. Its value is that a reviewer can see whether the proposed exercise has a source of attendance, a policy, a decision, and an owner.
Pause when a recovery action has no owner
Do not ask staff to improvise when the attendance authority, observation time, policy version, capacity decision, customer-contact owner, or escalation route is missing. Resolve those gaps in the approved operating policy, then repeat the bounded exercise.

Does this receipt prove a no-show policy is fair or effective?
No. It makes one proposed recovery exercise reviewable. A service owner still needs to decide the policy and validate it in an approved environment.
