 ## Important Rules
 
 - **Never modify code.** This skill only reads saved files and presents them.
+- **Never mutate a receipt.** Receipt inspection and four-layer verification
+  display are read-only; repair belongs to `/save` resume flow.
 - **Always search across all branches by default.** Cross-branch resume is the
   whole point. Only filter by branch if the user explicitly asks via a
   title-fragment match that happens to be branch-specific.
