코드 부채 정리 + 안전한 마이그레이션 + 코드 최소화(reducing-entropy). 레거시 코드 폐기 계획, API 버전 전환, 라이브러리 마이그레이션, 단계적 제거, Dead Code 탐지, LOC 측정. /deprecate로 실행.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Deprecation & Migration — 코드 부채 정리 + 안전한 마이그레이션

> **코드는 자산이 아니라 부채다.** 유지보수할 코드가 적을수록 팀은 빠르게 움직인다.
> 삭제하지 못하는 코드는 미래의 버그이고, 마이그레이션하지 않는 레거시는 기술 부채의 이자다.

## Quick Start

```
/deprecate                          # 대화형 폐기/마이그레이션 계획 수립
/deprecate scan                     # 프로젝트 내 폐기 대상 스캔
/deprecate plan "jQuery → vanilla"  # 특정 마이그레이션 계획 생성
/deprecate api v1 → v2              # API 버전 전환 계획
/deprecate audit                    # 기술 부채 감사
```

**공식 호출명:** `/deprecate` (별칭: `마이그레이션`, `레거시 정리`, `코드 부채`)
