Turn on nix-darwin's homebrew module with empty taps/brews/casks/masApps lists to fill in, onActivation autoUpdate+upgrade, and cleanup=none (manual formulae left intact; flip to zap for fully authoritative lists). Set system.primaryUser so brew activation runs as the host user.
Add the nix-darwin input (nix-darwin-26.05, follows nixpkgs) and a mkDarwinHost mirroring mkHost: shared commonModule (nixpkgs/nix settings) is factored out and reused, home-manager is wired via darwinModules, and identity is threaded through specialArgs.
New darwinConfigurations.lyrathorpe-mac (aarch64-darwin) reuses the cross-platform ./lyrathorpe/home modules (shell, git, editor); Linux-only sway/desktop modules are excluded. Build with: darwin-rebuild switch --flake .#lyrathorpe-mac.
Add path filters so the workflow triggers only when *.nix files, flake.lock, or the workflow itself change, skipping CI for docs/markdown/unrelated edits.
CI workflow gates on nixfmt formatting and evaluates all three host toplevels (aarch64 evaluates without emulation; no full builds in CI).
renovate.json enables the nix manager and weekly lockFileMaintenance for flake.lock, plus grouped github-actions updates (Renovate matches .gitea/workflows). A self-hosted Renovate workflow runs it on Gitea, since Gitea has no built-in Renovate; it needs a RENOVATE_TOKEN secret.
Move ./emmathorpe -> ./lyrathorpe (git mv preserves history) and rename the MBP/X1 nixosConfiguration names to lyrathorpe-mbp / lyrathorpe-x1c. The EDaaS host keeps its emmathorpe-edaas name and Emma Thorpe identity; it still imports the shared (renamed) config dir.
Derivation outputs are byte-identical to before; pure relabel.
Thread username and fullName per host through the flake host table and specialArgs / home-manager.extraSpecialArgs, so user.nix and git.nix derive identity instead of hardcoding it.
MBP and X1 now provision user lyrathorpe (Lyra Thorpe). EDaaS retains emmathorpe (Emma Thorpe) and its wsl.defaultUser; work commit email is unchanged.
Move git config to the settings option, switch to the standalone programs.delta module with git integration, add commitizen, and treat Jenkinsfiles as groovy.
Migrate git config to the settings option, fix the signing key path and email, add argo-rollouts/google-cloud-sdk and other tooling, enable go, and wire a dedicated nixpkgs-unstable input so claude-code tracks unstable independently of the pinned nixpkgs.
Enable rootful docker with Docker Desktop proxy patch, add emmathorpe to the docker group, disable resolvconf and enable nix-ld so the WSL distro behaves.
