# PR walkthrough

## Contract

| Field | Bound contract |
|---|---|
| Trigger | User wants a zoomable PR map or graph-canvas orientation. |
| Authority | Reversible local: writes only the output HTML site and scratch files under the working directory; rollback is deleting or overwriting prior output. No remote mutation. |
| Side effect | Writes a self-contained static HTML site to the output directory. |
| Done | Four D3 views (file dependency graph, commit timeline, change heatmap, review thread flow) each with a guided tour, in a single HTML file with all assets bundled locally and no external network dependency. |

## Inputs

- PR diff or branch diff. Required. Supply as a unified diff file, a git range (`base..head`), or a GitHub PR URL.
