 This is a NixOS flake-based configuration for multiple hosts:
 - **FredOS-Gaming** — gaming desktop
-- **FredOS-Mediaserver** — home media server

+- `hosts/` — per-host NixOS configuration modules (imported per-host by `mkHost` in flake.nix)
 - `hosts/hardware/` — hardware-specific configuration

-- `services/` — modular service definitions imported by hosts
+- `services/` — modular service definitions, gated by hostname with `lib.mkIf`
-- `settings/` — shared settings/variables
+- `settings/` — shared settings (desktop, hyprland, quickshell, stylix, …)
+- `modules/crowdsec/` — vendored crowdsec modules from nixpkgs PR #446307; delete once that PR lands in the pinned channel
+- `ports.toml` — WAN → LAN port forwards consumed by `services/router.nix`
+
+## Deployment
+
+Hosts never pull this repo locally — they rebuild from the Forgejo remote via the
+`update` alias (`nixos-rebuild switch --refresh --flake git+https://forg.gregersen.it/rope/nixos`).
+That means evaluation is **pure**: config can never read files outside the repo
+(e.g. `/var/secrets`) at eval time. Secrets must be injected at service runtime
+(see `services/crowdsec.nix` and `services/go2rtc.nix` for the pattern).

 ## Notes
 
-- `hosts/hardware/` files are committed to the repo — they contain UUIDs and disk layout but no sensitive credentials
+- The mediaserver is also the home router: `services/router.nix` owns nftables NAT/firewall and `networking.firewall` is **disabled** on that host. WAN exposure is controlled solely by `ports.toml`; LAN traffic is trusted wholesale.
-- Host-specific behaviour is gated with `lib.mkIf (config.networking.hostName == "...")` or `lib.elem config.networking.hostName [...]`
+- `hosts/hardware/` files are committed — they contain UUIDs and disk layout but no sensitive credentials
-- GitHub API rate limit (60 req/hour unauthenticated) can occasionally be hit if running `update` many times in quick succession during active config changes — wait ~15 minutes and retry
+- Host-specific behaviour is gated with `lib.mkIf (config.networking.hostName == "...")` or `lib.elem config.networking.hostName [...]`; host modules themselves are selected by `mkHost` in `flake.nix`
