# Line endings are part of these files' CONTENT, not a display preference.
#
# Git's Windows default is core.autocrlf=true, so without this file a stock clone
# materialises every text file with CRLF. Three things then break, all silently:
#
#   * the IR maps are read with `IFS=$'\t' read -r rel csv`, which splits on tabs only, so
#     the last field keeps its CR. The staging step looks for a file whose name ends in a
#     carriage return, never finds one, and takes the documented "absent CSV stages an empty
#     relation" branch. Every relation stages empty, the solve finds nothing, and the run
#     exits 0 with a graph containing no call sites and no edges.
#   * SCHEMA.md is byte-compared against freshly generated output, which is always LF. The
#     gate reports the committed file stale, and regenerating it does not help because it is
#     checked back in as CRLF.
#   * the engine id hashes the rule text, so CRLF rules hash differently: a published engine
#     built in CI is refused on a Windows clone as "built from other rules".
#
# Pinning to eol=lf keeps the working tree LF on every platform. The shell reads these files
# with bash, awk and sed, which want LF everywhere, and no editor needs them to be CRLF.
* text=auto eol=lf

# Binary, so git must never touch them. An engine binary rewritten by newline conversion is
# corrupt, and the checksum that guards it would be computed over the corruption.
