   Forgot to bump the CI, according to the touched files of the last bump: git show 8ea45e626e5a0482ee11d4376f961d8126ce7c7b --stat?

   Yea. However no point until the SDK is uploaded, and no point doing that until we’ve got determinism.

   This implies dropping x86_64-apple-darwin? Or do you just want to try the Apple Silicon target first to see if it’s deterministic?

   No, this isn’t dropping support for any build targets. IIrc this is the version of Xcode that only runs on Apple Silicon, which I chose because the download is smaller, and this doesn’t make any difference to the extracted SDK.

   Checksum matches on my Apple M4 Pro with macOS 26.2.

   I also got this sha256 sum on Ubuntu x86_64.
