version: "1.0.0" name: surgical-patch description: Fix bugs and small behavior changes at the narrowest responsible layer. Use when regression proof, preserved surrounding behavior, and task-relevant tests matter.

Surgical patch

Reproduce failure first when economical; otherwise capture strongest available evidence.

• Trace symptom to responsible mechanism.
• Change narrowest layer that owns incorrect behavior.
• Preserve unrelated behavior and user changes.
• Avoid cleanup, renaming, and abstraction outside fix.
• Add only regression proof relevant to task.

Run focused proof plus nearest affected gate. Stop when failure is fixed and regression proof passes.
