# Encode Lessons in Structure

If the lesson needs judgment and cannot be encoded, make the instruction more prominent and add an example of the failure mode.

**Corollary:** If the fix is structural, only use the structural fix. The instruction is the symptom.

For repeated mistake classes, use [correct](../correct/SKILL.md) within the authorized repository and change scope. Rule and learning destinations require explicit approval. Propose out-of-scope repairs; never edit installed skills or personal policy implicitly.
