Wires sops-nix as a flake input and bakes the NixOS module into
configuration.nix via modules/secrets.nix. Per-host defaults live in
modules/secrets.nix:
- defaultSopsFile = ../secrets/${settings.hostName}.yaml
- defaultSopsFormat = yaml
- age.keyFile = /home/${settings.user}/.config/sops/age/keys.txt
The whole sops block is gated on `builtins.pathExists` so flake eval
succeeds before the encrypted file is created — important during the
scaffold-bootstrap phase where the consumer hasn't yet generated an
age key.
Adds .sops.yaml with a placeholder admin recipient (overwrite with
your real age public key before encrypting anything) and a
creation_rules block matching `secrets/*.yaml`.
.gitignore loosened so `secrets/*.yaml` and `secrets/README.md` can
be checked in while plaintext key material (`*.key`, `*.pem`) and
anything else under `secrets/` stays ignored. The pre-commit secret
scanner most consumers use is the second line of defense.
secrets/README.md documents the workflow at the directory level.
The substantive beginner walkthrough lands in a follow-up commit at
docs/secrets-management.md.
`nix flake check --no-build` stays green.

Three blockers off the path so the skeleton evaluates cleanly:
1. flake.lock generated (no inputs were pinned before).
2. hardware-configuration.nix shipped as a placeholder — unbootable
/dev/null root + grub on nodev — so `system.build.toplevel` resolves
without complaining about missing fileSystems / boot.loader. The
file carries a big "overwrite with nixos-generate-config" warning;
the consumer regenerates it before any real switch.
3. Primary user + group declared in configuration.nix (was tripping
the assertion about implicit nogroup defaults and isNormalUser
missing).
Also: `home.homeDirectory` now uses `lib.mkForce` to override
home-manager's nixos-module default of /var/empty, and the deprecated
`programs.git.user{Name,Email}` options migrated to the new
`programs.git.settings.user.{name,email}` shape.
`nix flake check --no-build` now finishes with `all checks passed!`
and no warnings, giving every subsequent change a cheap signal.
