Cs Issue Fix

This handles stage 3 of a bug workflow: taking a confirmed root cause and fix plan, implementing the minimal code changes, verifying the fix works, and writing a fix-note.md to close the loop. It enforces strict scope discipline by only touching files declared in the analysis phase and blocking "drive-by refactoring" that would muddy the PR. The skill runs verification checklists for reproduction steps, expected behavior, and regression surfaces, then switches to log-based debugging if the fix doesn't work instead of letting you guess repeatedly. It's opinionated about keeping bug fixes surgical and traceable, which feels restrictive at first but keeps git blame clean and code review focused.
