Git for Windows installs with core.autocrlf=true, so every repository the
suite creates checked committed LF files out as CRLF and byte-exact content
assertions in GitManager, CheckpointReactor, and the orchestration engine
integration test compared 'v2\r\n' against 'v2\n'. A vitest setup file
now pins autocrlf, filemode, longpaths, gpgsign, and the default branch
through GIT_CONFIG_* so every git child the driver spawns sees them, ahead
of whatever the host's ~/.gitconfig says.

Two tests compared an Effect realPath of os.tmpdir() against git's own
report of the same directory; on GitHub's Windows runners the temp dir is
spelled with its 8.3 short name (RUNNER~1) and only realpathSync.native
expands it. The newline-in-worktree-path test is skipped on Windows, where
NTFS rejects the name outright.
