# Maintain tax payable mapping during the Commerce transition: Capability Test Specification

## Coverage

- Resolve payable accounts at posting.
- Validate criteria for each zone kind.
- Bound rate definitions.
- Retain issued tax after zone replacement.
- Select zones in order with a default country.
- Protect tax classes already referenced.

The structured coverage map distinguishes specified examples from remaining findings. Proposed examples require executable proof before qualification.

## Interactions With Related Capabilities

- Default tax mapping supplies an unmapped rate.

Related-capability and workflow references identify the seams each scenario exercises. The lifecycle coverage record retains transitions that still need individual proof.

## Binding Review

The pinned service and browser assertions support the registered bindings. Original test references remain beside each scenario so partial evidence and unresolved conformance remain reviewable.
