When running nix flake check I get this error:
error: a 'aarch64-darwin' with features {} is required to build '/nix/store/wprydkf14qwvnnyz8vvhbn7rbhchr8rz-cabal2nix-borsh.drv', but I am a 'x86_64-linux' with features {benchmark, big-parallel, kvm, nixos-test, uid-range}
I am importing these libraries into the main flake like this:
flake-parts.lib.mkFlake {inherit inputs;} {
systems = nixpkgs.lib.systems.flakeExposed;
imports = [
inputs.haskell-flake.flakeModule
];
perSystem = {
self',
config,
pkgs,
inputs',
system,
...
}: {
haskellProjects.default = {
imports = [
inputs.zcash-haskell.haskellFlakeProjectModules.output
inputs.persistent-sqlite.haskellFlakeProjectModules.output
inputs.qrc.haskellFlakeProjectModules.output
];
...
};
The new addition is the qrc library and I don't understand why this is causing nix to try to build the wrong architecture for borsh. All these flakes pass their checks and build correctly on their own.

Research direction
Reproduce the failure with nix flake check from the main flake and inspect the perSystem Haskell project imports for zcash-haskell, persistent-sqlite, and qrc. Trace the qrc dependency path through foreign-rust and borsh, focusing on why cabal2nix-borsh.drv requests aarch64-darwin on x86_64-linux. Done means the architecture mismatch is explained and the relevant flake checks behave consistently.
