Ah, I think I know what's up. pre-commit needs dotnet, but it has:

    # fixes: Could not load ICU data. UErrorCode: 2
    propagatedSandboxProfile = lib.optionalString stdenv.hostPlatform.isDarwin ''
      (allow file-read* (subpath "/usr/share/icu"))
      (allow file-read* (subpath "/private/var/db/mds/system"))
      (allow mach-lookup (global-name "com.apple.SecurityServer")
                         (global-name "com.apple.system.opendirectoryd.membership"))
    '';

      "__sandboxProfile": "(allow file-read* (subpath \"/usr/share/icu\"))\n(allow file-read* (subpath \"/private/var/db/mds/system\"))\n(allow mach-lookup (global-name \"com.apple.SecurityServer\")\n                   (global-name \"com.apple.system.opendirectoryd.membership\"))\n ",

How would you read a <| b |> c ?

(a <| b) |> c or a <| (b |> c)

Currently it is syntax error for some reason.

chatgpt says

In languages that support both (e.g. F#), the binding strength is such that:

<| has lower precedence (binds less tightly) than |>.

Both are right-associative.

so the verbot to use them both in the same expression is unique to Nix

ok I did

    extra_nix_config: ${{ matrix.os == 'darwin' && 'sandbox = "relaxed"' || 'sandbox = true' }}

Hey peeps, I unknowingly ran into the leaveDotGit bug of unpredictable hash generation for nix derivations. I patched the dependency, but now ofborg says that my provided hash is wrong:
´´´bash
error: hash mismatch in fixed-output derivation '/nix/store/q59g9bk2kwh20sr8ir00gz5d5yjkb75r-source.drv':
specified: sha256-HoqFBkxXlmbWaFPOVvO0zUhlDBVzz++T6Fgf0MAuyao=

error: 1 dependencies of derivation '/nix/store/q5izjyv5iv1h0zdc06my4dp07wvv9j76-KnobKraft-orm-2.7.1.drv' failed to build
´´´

The point that I don't understand is that every architecture, aarch64, x64_86, etc. all have different hashes. However, I just want to build it for x64_86_linux. So how do I tell ofborg to only build on one architecture and why does the hash that works locally not work with ofborg?
