Diff Integrity

Why this rule exists

Mixed-scope diffs hide intent. When a single commit reformats whitespace, renames variables, and fixes a bug, reviewers cannot tell which lines actually change behavior. Bugs ride into production under cover of noise.

Code example

// Same commit: reformats 200 lines AND changes a calculation
- decimal total = price + tax;
+ decimal total = (price + tax) * discount;
+ // ...plus 200 lines of unrelated reformatting

// Commit 1: reformatting only
// Commit 2: behavioral change
- decimal total = price + tax;
+ decimal total = (price + tax) * discount;
