# Line endings are part of this repository's published claims.
#
# Git stores text with LF. Without this file, a Windows checkout with
# core.autocrlf=true materializes CRLF in the working tree while a Linux
# checkout materializes LF, so the same commit has different bytes on disk
# depending on who checked it out. Anything that hashes working-tree bytes then
# gets a different answer per platform.
#
# That is not hypothetical here: the checkpoint-B artifact regression gate
# hashes artifacts/evaluations/checkpoint-b/raw-results.json as checked out. Its
# committed expectation was generated on Windows (CRLF), so CI on Linux computed
# a different digest and failed on every push since the first public commit.
#
# Normalizing the working tree to LF everywhere makes a checkout byte-identical
# on every platform, which is the property a byte-level gate needs to mean
# anything. text=auto still leaves genuinely binary files alone.
