Stand up the walking skeleton the rest of the laptop MVI extends and re-verifies against: the whole neogaia Host evaluates and its system toplevel builds (nix flake check green). - flake.nix: hand-rolled flake (no flake-parts). Base nixos-unstable, plus nixpkgs-unstable and nixos-25.05 for the per-package unstable/stable overlays, home-manager (nixpkgs followed), and chaotic-nyx (deliberately not following our nixpkgs, to keep its binary cache usable). checks build each Host toplevel. - lib/: trimmed helper lib — the Auto-loader (recursive .nix discovery, no null-placeholder hack), the host-builder, and the script-from-file helper. Deps inherited explicitly; no with lib.my, no nixosModules output. - system/: shared base config — the unstable/stable overlays, the user option (defaults to alexion, in wheel, drives system + home-manager user in lockstep), flakes, git, and home-manager as a NixOS module. - modules/example.nix: Auto-loader / Enable-convention reference Module, inert until enabled. - hosts/neogaia/: minimal laptop Host — placeholder filesystems, bootloader, and hardware profile. - CLAUDE.md: project agent instructions with a Gotchas section (nix on the CachyOS dev host, the chaotic overlay/cache behaviour, the forge CLI).
