Walkthrough

Explain a completed change with a few annotated visuals. Run this after final verification. A walkthrough explains proof; it does not replace proof.

Honor The Caller Contract

The caller decides whether the walkthrough is required. Follow the stricter repo rule when one exists.

For UI-gated workflows, treat app pages, websites, components, styles, visual content, and generated or rendered output as UI changes. If the packet changed one of those surfaces, run the walkthrough in the final handoff.

When the caller requires a walkthrough and it cannot be produced, block closeout with the exact missing tool, access, or artifact. Do not waive it silently.
