feat(scanner): add Docker disk image scanning (scan only) - #32
Merged
Conversation
Report the Docker Desktop VM disk image (Docker.raw) as a protected artifact. It is a stat-based scanner: a fixed home-relative path, scope- gated by the scan root like xcode/global. The image is marked Protected so the cleaner refuses to path-delete it — all Docker state lives in that one sparse file. Sizing runs through the shared sparse-aware Measure, so a 460G-declared image reports its real ~8G on-disk usage (Size) alongside the declared size (ApparentSize) with no Docker-specific code. Reclaiming space via `docker system prune` is destructive and stays deferred behind a future --include-destructive gate; this change reports the image and its footprint only, it does not wire up prune.

Refs #17 (scan track only —
docker system prunewiring deferred)요약
Docker Desktop VM 디스크 이미지(
Docker.raw)를 protected 아티팩트로 스캔한다. stat 기반 스캐너(xcode/global과 동형: 고정 home-relative 경로 + scan root scope 게이트).~/Library/Containers/com.docker.docker/Data/vms/0/data/Docker.raw(기본 경로만; 비기본 data root 미추적)Protected: true로 cleaner가 path 삭제 거부.Measure로 460G 선언 이미지가 실제 점유(~8G)로 산출. Docker 전용 sizing 코드 없음.스코프 결정 (이슈와의 차이)
이슈 완료조건은 "vendor prune 연동"까지지만,
docker system prune은 파괴적(이미지·볼륨·빌드캐시 삭제)이고 프로젝트 CLAUDE.md가 이를--include-destructive게이트 뒤로 미루도록 명시한다. 그 게이트는 현재 없음.게이트는 Docker 전용이 아닌 크로스커팅 기능(CLI 플래그 + VendorCleanup destructive 필드 + 필터 + 확인 UX)이라 별도 트랙으로 분리했다. 이 PR은 스캔·protected·실측 트랙만 완결하고, prune 연동은 게이트 신설 작업으로 남긴다. 이슈 17은 close하지 않음.
