SHA1 is the primary key of this collection and there was no
.gitattributes, so git guessed. Git for Windows sets core.autocrlf=true
by default: a clone there rewrites every file git considers text,
meaning the shaders, .ini, .txt and .dat assets under bios/ arrive with
CRLF and a different hash from the one published. Verification then
fails on files nobody touched.
bios/ and data/ are exempt from normalisation, generated artefacts are
pinned to LF so a Windows checkout does not show them modified, and the
rule order is asserted rather than assumed.
