Paired Implementation Consistency

Why this rule exists

Parallel implementations of the same behavior with inverted predicates usually indicate a copy/paste logic bug rather than an intentional difference.

Code example

+ // FooValidator and BarValidator disagree on the same IsActive check
+ if (!user.IsActive) return;
+ if (user.IsActive) return;

+ // Both validators use the same polarity or document why they differ
