name: differential-feature-refactor
description: >-
  Use when a feature already exists in code but has drifted from — or was never reconciled
  with — its intended design, and someone must decide what changes before a refactor is
  scoped. Triggers: two parallel implementations of the same thing, code that reads as dead
  but may be a ratified extension point, an architecture nobody can tell from accumulated
  cruft, or a refactor about to be scoped off review documents instead of decisions.
