# Repository whitespace check. `git diff --check` alone only inspects
# unstaged modifications to already-tracked files, so it silently passes on
# untracked new files (every Phase 0 artifact starts out untracked) and is a
# no-op on a clean checkout. Check every tracked-or-untracked, non-ignored,
# non-binary file directly for trailing whitespace instead. Markdown is
# excluded: a trailing double-space is CommonMark's hard-line-break syntax,
# not sloppy whitespace, and the plan document uses it intentionally.
