# 18 - Double-edged evidence across criteria

## Input
One evidence item describes a decision pushed through quickly over peer objections: it
matches an effective indicator on a pace-of-execution criterion and an ineffective
indicator on a collaboration criterion.

## Correct behavior
- The item carries two coding entries with different computed valences (positive for one
  criterion, negative for the other); the validator accepts both.
- Both criteria's statuses reflect their own valence; the prose interprets the tension
  rather than averaging it away.

## Fail conditions
- Forcing a single valence across criteria.
- The validator or builder rejecting a legitimately double-edged item.
