# Line endings, decided here rather than by whoever cloned the repository.
#
# Without this file git normalises on commit and translates on checkout
# according to each developer's `core.autocrlf`. For source that is harmless.
# For a `.tooltrace` bundle it is not: the manifest carries a SHA-256 of every
# file, taken over the bytes on disk, so a translated checkout hashes to
# something else and `tooltrace verify` reports a checksum mismatch on a bundle
# nobody touched.
#
# That is not hypothetical. Bundles regenerated on Windows were committed with
# CRLF content and CRLF checksums, and CI failed on macOS and Linux with six
# checksum mismatches per bundle.

# Source: normalised to LF in the repository, checked out as LF everywhere.
* text=auto eol=lf

# Published artifacts: byte-exact, never translated, on any platform. These are
# checksummed and reproduced; a newline "fixed" in transit breaks both.
