# Visual argument diagram
## Contract
| Field | Bound contract |
|---|---|
| Trigger | User wants to create a conceptual, workflow, architecture, or protocol diagram, repair an existing diagram's visual layout, or render an existing `.excalidraw` file to PNG without editing it (render-only mode). |
| Authority | Reversible local: writes only named artifacts; rollback is deleting those files on failure or quality non-convergence. In render-only mode the source `.excalidraw` file is read-only and no partial PNG is ever written. No remote mutation. |
| Side effect | Writes one `.excalidraw.json` file and one `.png` render (create or repair), or one `.png` only (render-only). First run may bootstrap pinned Playwright/Chromium. |
| Done | Create or repair: JSON and PNG exist; rendered vision and defect checks pass for conceptual structure, evidence, eye flow, dominance, clipping, overlap, arrow routing, spacing, balance, and export readability; fewer than 30% of text elements are container-bound. Render-only: the PNG exists on disk and represents the source diagram at the requested scale; the source file is unmodified. |
