+"""Check that no root-anchored `.dockerignore` entry excludes tracked files.
+
+Docker builds bind-mount `.git` but copy the working tree through the build
+context, so git sees any tracked file that `.dockerignore` drops as deleted.
+That dirty tree fails `tools/check_repo.sh` in release builds
+(`GIT_REPO_CHECK=1`) and adds a `.dYYYYMMDD` dirty suffix to the wheel version.
+
+Usage:
+    python tools/pre_commit/check_dockerignore_tracked.py
