# Blast radius

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Determine what a change could break. |
| Authority | Reversible local: writes only one local proof script or test; rollback is deleting it after the report. No remote mutation. No VCS, credential, or published mutation. |
| Side effect | May write and run one proof. |
| Done | Confirmed risks, cleared items, and cheapest pre-merge test. |

## Inputs

A diff, branch, or set of changed files to analyze. The change must be readable from the working tree or a supplied patch. Optional: the running application for in-app reproduction.
