# ⚠ Pin line endings for source, so a Windows checkout cannot change file bytes.
#
# Git for Windows defaults to `core.autocrlf=true`, which rewrites LF to CRLF on
# checkout. That is invisible until something reads a source file as TEXT rather
# than compiling it, and this repo does exactly that: several tests scan their
# own source to assert an invariant nothing else can hold (that a gate is wired
# into dispatch, that a module's tests live where its docs claim). Two of those
# needles contain `\n`, so on Windows they matched nothing and the tests failed
# for eighteen days for a reason that had nothing to do with the code.
#
# Normalising in each test works and is what shipped, but it treats a repository
# property as a per-test concern and the next such test will be written without
# it. This is the root fix.

# ⚠ The vendored Computer Use tree is HASHED, file by file, into
# `vendor/computer-use/source-manifest.json`, and the build verifies
# those hashes before the bytes become build input. So its bytes must be
# byte-identical on every platform, not merely equivalent.
#
# `-text` disables end-of-line conversion entirely — stronger than `text eol=lf`,
# which still declares the file text and invites tooling to normalise it. The
# rules above cover source by EXTENSION, and this tree is full of files that have
# none: `LICENSE`, `Makefile`, `CODEOWNERS`, `.gitignore`, `.gitattributes`.
# Measured on CI before this rule: a Windows checkout rewrote exactly those five
# to CRLF and the manifest check failed with `changed=['.gitattributes',
# '.gitignore', 'CODEOWNERS', 'LICENSE', 'Makefile']`, on a tree nobody had
# edited.
