Implementation Notes for Capturing Decision Evidence at Merge Points

Merge points combine work from parallel branches, and recording which inputs and rules produced the merged result is what makes later disputes resolvable.

When parallel branches disagree, the merge decides. Six weeks later, someone will ask why it decided that way, and the answer either exists in the record or does not exist at all.

Evidence to capture

• The candidate values from each branch, with versions.
• The rule or arbiter that selected the winner.
• What happened to the losing branches, retired or escalated.

Use the audit schema, architecture guide, and examples to make every merge outcome explainable from its recorded inputs.
