Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Adding a host Copy the closest existing host and change what differs. The current inventory and naming scheme are in [hosts/README.md](../../../hosts/README.md). ## Core rules 1. **Three names, decided up front.** The directory (`hosts/idols-ai/`), the hostname (`hostName = "ai"`), and the configuration name (`ai-niri`) differ. Servers use the hostname as the configuration name; Niri desktops append `-niri`, because `just niri` deploys `$(hostname)-niri`. The `hostname` eval test encodes this. 2. **Secrets come from another repository.** The new host decrypts nothing until its host key is a recipient in `nix-secrets`; see the `nix-config-secrets` skill. A new desktop also needs its synced dotfiles restored before the first switch, or the shell starts without them. 3. **The shared policy modules are not optional.** Several eval tests assert a policy for every configuration, so an under-wired host fails `just test` instead of failing in production. 4. **Build before you install.** `just test`, `just eval-host <name>`, and `just build-host <name>` pass before anything is partitioned or flashed. `disko` destroys the target disk, and …

How to install
mdr add ryan4yin/nix-config/nix-config-new-host@sha256:84f95accd4118e91The line at the top of this page pins the label git:20261010.0e70582, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
