ADM.9:0 - Use this when

Use this pattern when a participant needs an authorized administrative condition to become usable, or when an approval or completion message does not establish that the promised result is available. Typical cases are access that still fails, accommodation that cannot be occupied or a payment instruction whose effect is unknown.

Start with what the recipient must be able to do and the provider action expected to make that possible. The first useful result is the promised usable condition with adequate evidence, or the exact remaining provision failure and accountable next action.

Use an adequate existing provision and recovery instruction directly. A request only for a permission answer can finish under ADM.8; a service whose promised result is a booking can finish with a usable booking. The completion criterion follows the actual promise, not a universal demand to prove all later business outcomes.
