+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## What This Repo Is
+
+A NixOS flake configuration managing multiple hosts (desktops, laptops, servers). All hosts share common settings via `hosts/configuration_common.nix` and are assembled in `hosts/default.nix`.
+
+## Common Commands
+
+```bash
+# Format all nix files
+nix fmt
+
+# Build a host configuration (no activation)
+nixos-rebuild build --flake .#<host>
+
+# Switch the current host
+sudo nixos-rebuild switch --flake .#<host>
+
+# Build a custom package
+nix build .#<package>
+
+# Edit an age-encrypted secret
+agenix -e secrets/<path>.age
+
+# Re-key all secrets after adding a new host key to secrets/secrets.nix
+agenix -r
+```
+
+## Architecture
+
+### Entry Points
+
+- `flake.nix` — defines inputs (nixpkgs stable=25.11, unstable, home-manager, agenix, lanzaboote, jovian-nixos, microvm, impermanence, noctalia) and calls `hosts/default.nix` for `nixosConfigurations`
+- `hosts/default.nix` — instantiates every host via `lib.nixosSystem`; contains the `mkHM` helper that wires home-manager into a host's modules list
+
+### Host Structure
+
+Each host lives in `hosts/<name>/`:
+- `default.nix` — imports either `../../modules/desktop` or `../../modules/server`, sets the module options (`myDesktop.*` / `myServer.*`), and adds host-specific settings
+- `home.nix` — host-specific home-manager config (merged with `hosts/home.nix` for desktops or `hosts/home_server.nix` for servers)
+- `hardware-configuration.nix` — generated hardware config
+
+Shared host-level files:
+- `hosts/configuration_common.nix` — applied to every host: SSH (key-only, no root), locale, nix GC/settings, zsh, fonts, auto-upgrade flake URL
+- `hosts/home.nix` — desktop home-manager base
+- `hosts/home_server.nix` — server home-manager base
+
+### Module System
+
+Two top-level NixOS modules expose all major knobs as typed options:
+
+**`modules/desktop/default.nix`** — `myDesktop.*`
+- `windowManager`: `"niri"` (default) | `"sway"` | `"kde"`
+- `cpu`: `"amd"` | `"intel"` | `"none"` — selects KVM kernel params
+- `virtualisation.enable` — podman (docker-compat) + qemu/libvirt + virt-manager
+- `syncthing.{enable,devices,folders}`
+- `openrgb.{enable,motherboard}`
+- `laptop.{enable,lidSwitch,hibernateDelaySec}`
+- `nitrokey.enable`
+- `niri.hotkeyVariant`: `"default"` | `"lifebook"`
+- `git.signingKey` — SSH key for commit signing
+- `extraSystemPackages`
+
+**`modules/server/default.nix`** — `myServer.*`
+- `sshPort` (default 2220)
+- `virtualisation.{enable,cpu}` — podman only (no libvirt)
+- `fail2ban.enable`
+- `autoUpgrade.enable` (default true)
+- `uid`, `sudoRequiresPassword`, `extraGroups`, `extraSystemPackages`
+
+Service bundles are imported as lists in host `default.nix`:
+- `modules/services/server/` — kabtop services (gitea, nextcloud, matrix, coturn, hydra, mealie, etc.)
+- `modules/services/nas/` — jupiter services (nfs, vaultwarden, syncthing, paperless)
+- `modules/services/dmz/` — dmz services (gitea runner microVM)
+- `modules/services/kabtopci/` — kabtopci services (hydra, gitea runner)
+- `modules/services/nasbackup/` — nasbak backup jobs
+
+### Secrets (agenix)
+
+`secrets/secrets.nix` declares which age public keys (users + host SSH keys) can decrypt each `.age` file. Add a new host: add its `ssh-ed25519` host key to `secrets/secrets.nix` in the relevant groups, then run `agenix -r` to re-key.
+
+### Custom Packages & Overlays
+
+- `packages/` — custom packages (e.g. `corosync-qdevice`), imported at `flake.nix` level
+- `overlays/` — nixpkgs overlays applied globally
+- Per-host overlays: set `nixpkgs.overlays` inside the host's `default.nix` so only that host is affected
+
+### Disk Layouts
+
+`disko/` contains reusable disko modules: `btrfs.nix`, `btrfs_luks.nix`, `nas_luks.nix` — referenced during initial install.
+
+## Active Hosts
+
+| Host | Role | WM / Notes |
+|---|---|---|
+| hades | Desktop | niri, AMD, Secure Boot (lanzaboote) |
+| lifebook | Laptop | niri, Intel, Secure Boot |
+| steamdeck | Gaming | KDE/Jovian-NixOS, Secure Boot |
+| kabtop | Main server | gitea, nextcloud, matrix+bridges, coturn, hydra, mealie |
+| kabtopci | CI server | hydra, nix-serve |
+| jupiter | NAS | nfs, vaultwarden, syncthing, paperless |
+| dmz | DMZ | gitea Actions homerunner microVM |
+| nasbak | NAS backup | — |
+| kubemaster-1 | K8s master | — |
+
+See `SERVICES.md` for port-level service details per host.
