There is no way to see the raw nix commands Coleman is calling?

Not at the moment and I really should add a bunch of debug prints. You can manually evaluate from the repo with

nix-instantiate -E 'let eval = import ./src/nix/hive/eval.nix; hive = eval { rawHive = import ./path/to/your/hive.nix; }; in hive.nodes.helios64.config.system.build.toplevel'

If I run

NIX_PATH=nixpkgs=https://github.com/NixOs/nixpkgs/archive/nixpkgs-21.11-darwin.tar.gz colmena build

I get
