majiayu000 Refactor — one structural experiment
Refactor changes structure while preserving observable behavior. It performs one caller-selected transformation and reports the result.
Procedure
- Name the preserved behavior and the focused acceptance surface.
- Record an honest baseline, including any reproducible ambient failures.
- Apply one bounded transformation: extract, rename, inline, simplify, encapsulate, move, or delete dead code.
- Run the focused check and the smallest package-level regression check justified by the changed surface.
- Return the diff summary, commands, results, and behavior not checked.
Do not combine a newly discovered behavior fix with the structural change. A red result is evidence for the caller; this skill does not revert, narrow, retry, commit, validate, or route subsequent work automatically.
