+#### How to Complete the Audit Template
+
+- **Acceptance Criterion:** Copy the exact requirement from the issue.
+- **Implementation Evidence:** List the files modified, attach a screenshot, or explain the change.
+- **Test Evidence:** Reference the automated test file, or describe the manual verification step.
+- **Documentation Impact:** List any updated documentation files, or write "None needed" if applicable.
+- **Status:** Must be exactly one of: `Complete`, `Partial`, `Not Applicable`, `Not Implemented`.
+
+#### Handling Incomplete Criteria
+
+When a piece of work cannot be fully completed in the current pull request:
+- Explain why a criterion is incomplete in the *Implementation Evidence* column.
+- Link to follow-up issues if applicable.
+- Clearly distinguish completed work from future work.
+- Avoid marking incomplete work as complete (use `Partial` or `Not Implemented`).
