+Title: Add nix-darwin Support to Clan Services (clan.service)
+
+Summary
+- Extend clan services so authors can ship a darwinModule alongside nixosModule.
+- Wire service results into darwin machines the same way we already do for NixOS.
+- Keep full backward compatibility: existing services that only export nixosModule continue to work unchanged.
+
+Goals
+- Service authors can return perInstance/perMachine darwinModule similarly to nixosModule.
+- Darwin machines import the correct aggregated service module outputs.
+- Documentation describes the new result attribute and authoring pattern.
+
+Non-Goals (initial phase)
+- No rework of service settings schema or UI beyond documenting darwinModule.
+- No OS-specific extraModules handling (we will keep extraModules affecting only nixos aggregation initially to avoid breaking existing users).
+- No sweeping updates of all services; we’ll add a concrete example (users) and leave others to be migrated incrementally.
+
+Design Overview
+- Service result attributes gain darwinModule in both roles.<name>.perInstance and perMachine results.
+- The service aggregator composes both nixosModule and darwinModule per machine.
+- The machine wiring picks the correct module based on the machine’s class (nixos vs darwin).
+
+Changes By File (with anchors)
+- lib/inventory/distributed-service/service-module.nix
+  - Add darwinModule to per-instance return type next to nixosModule.
+    - Where: lib/inventory/distributed-service/service-module.nix:536 (options.nixosModule = mkOption { … })
+    - Action: Add sibling options.darwinModule = mkOption { type = types.deferredModule; default = { }; description = "A single nix-darwin module for the instance."; }.
+  - Add darwinModule to per-machine return type next to nixosModule.
+    - Where: lib/inventory/distributed-service/service-module.nix:666 (options.nixosModule = mkOption { … })
+    - Action: Add sibling options.darwinModule = mkOption { type = types.deferredModule; default = { }; description = "A single nix-darwin module for the machine."; }.
+  - Compose darwinModule per (role, instance, machine) similarly to nixosModule.
+    - Where: lib/inventory/distributed-service/service-module.nix:878–893 (wrapper that builds nixosModule = { imports = [ instanceRes.nixosModule ] ++ extraModules … })
+    - Action: Build darwinModule = { imports = [ instanceRes.darwinModule ]; }.
+      Note: Do NOT include roles.*.extraModules here for darwin initially to avoid importing nixos-specific modules into darwin eval.
+  - Aggregate darwinModules in final result.
+    - Where: lib/inventory/distributed-service/service-module.nix:958–993 (instanceResults builder and final nixosModule = { imports = [ machineResult.nixosModule ] ++ instanceResults.nixosModules; })
+    - Actions:
+      - Track instanceResults.darwinModules in parallel to instanceResults.nixosModules.
+      - Add final darwinModule = { imports = [ machineResult.darwinModule ] ++ instanceResults.darwinModules; }.
+
+- modules/clan/distributed-services.nix
+  - Feed the right service module to each machine based on machineClass.
+    - Where: modules/clan/distributed-services.nix:147–152
+    - Current: machineImports = fold over services, collecting serviceModule.result.final.${machineName}.nixosModule
+    - Change: If inventory.machines.${machineName}.machineClass == "darwin" then collect .darwinModule else .nixosModule.
+
+- modules/clan/module.nix
+  - Ensure machineImports are included for both nixos and darwin machines.
+    - Where: modules/clan/module.nix:195 (currently ++ lib.optionals (_class == "nixos") (v.machineImports or [ ]))
+    - Change: Include machineImports for darwin as well (or remove the conditional and always append v.machineImports).
+
+- docs/site/decisions/01-Clan-Modules.md
+  - Document darwinModule as a result attribute.
+    - Where: docs/site/decisions/01-Clan-Modules.md:129–146 (Result attributes and perMachine text mentioning only nixosModule)
+    - Change: Add “darwinModule” to the Result attributes list and examples, mirroring nixosModule.
+
+- Example service update: clanServices/users/default.nix
+  - Add perInstance.darwinModule and perMachine.darwinModule mirroring nixos behavior where feasible.
+    - Where: clanServices/users/default.nix:28–90 (roles.default.perInstance.nixosModule), 148–153 (perMachine.nixosModule)
+    - Change: Provide minimal darwinModule that sets users.users.<name> (and any safe, cross-platform bits). If some nixos-only settings (e.g., systemd hooks) exist, keep them nixos-only.
+
+Implementation Steps
+1) Service API extensions
+   - Add options.darwinModule to roles.*.perInstance and perMachine (see anchors above).
+   - Keep defaults to {} so services can omit it safely.
+
+2) Aggregation logic
+   - result.allRoles: emit darwinModule wrapper from instanceRes.darwinModule.
+   - result.final:
+     - Collect instanceResults.darwinModules alongside instanceResults.nixosModules.
+     - Produce final darwinModule with [ machineResult.darwinModule ] ++ instanceResults.darwinModules.
+   - Leave exports logic unchanged.
+
+3) Machine wiring
+   - modules/clan/distributed-services.nix: choose .darwinModule vs .nixosModule based on inventory.machines.<name>.machineClass.
+   - modules/clan/module.nix: include v.machineImports for both OS classes.
+
+4) Example migration (users)
+   - Add darwinModule in clanServices/users/default.nix.
+   - Validate that users service evaluates for a darwin machine and does not reference nixos-specific options.
+
+5) Documentation
+   - Update ADR docs to mention darwinModule in Result attributes and examples.
+   - Add a short “Authoring for Darwin” snippet showing perInstance/perMachine returning both modules.
+
+6) Tests and verification
+   - Unit-level: extend lib/inventory/distributed-service/tests to assert presence of result.final.<machine>.darwinModule when perInstance/perMachine return it.
+   - Integration-level: evaluate a sample darwin machine (e.g., inventory.json has test-darwin-machine) and assert clan.darwinModules.<machine> includes the aggregated module.
+   - Sanity: ensure existing nixos-only services still evaluate unchanged.
+
+Backward Compatibility
+- Existing services that only return nixosModule continue to work.
+- Darwin machines won’t import service modules until services provide darwinModule, avoiding accidental breakage.
+- extraModules remain applied only to nixos aggregation initially to prevent nixos-only modules from breaking darwin evaluation. We can add OS-specific extraModules in a follow-up (e.g., roles.*.extraModulesDarwin).
+
+Acceptance Criteria
+- Services can return darwinModule in perInstance/perMachine without errors.
+- Darwin machines import aggregated darwinModule outputs from all participating services.
+- nixos behavior remains unchanged for existing services.
+- Documentation updated to reflect the new attribute and example.
+
+Rollout Notes
+- Start by updating clanServices/users as a working example.
+- Encourage service authors to add darwinModule incrementally; no global migration is required.

+!!! Danger "Experimental"
+    This service is for demonstration purpose only and may change in the future.
+
+The Hello-World Clan Service is a minimal example showing how to build and register your own service.
+
+It serves as a reference implementation and is used in clan-core CI tests to ensure compatibility.
+
+## What it demonstrates
+
+- How to define a basic Clan-compatible service.
+- How to structure your service for discovery and configuration.
+- How Clan services interact with nixos.
+
+## Testing
+
+This service demonstrates two levels of testing to ensure quality and stability across releases:
+
+1. **Unit & Integration Testing** — via [`nix-unit`](https://github.com/nix-community/nix-unit)
+2. **End-to-End Testing** — via **NixOS VM tests**, which we extended to support **container virtualization** for better performance.
+
+We highly advocate following the [Practical Testing Pyramid](https://martinfowler.com/articles/practical-test-pyramid.html):
+
+* Write **unit tests** for core logic and invariants.
+* Add **one or two end-to-end (E2E)** tests to confirm your service starts and behaves correctly in a real NixOS environment.
+
+NixOS is **untyped** and frequently changes; tests are the safest way to ensure long-term stability of services.
+
+```
+               / \
+              /   \
+             / E2E \
+            /-------\
+           /         \

+         /-------------\
+        /               \
+       /    Unit Tests   \
+       -------------------
+```
+
+### nix-unit
+
+We highly advocate the usage of
+
+[nix-unit](https://github.com/nix-community/nix-unit)
+
+Example in: tests/eval-tests.nix
+
+If you use flake-parts you can use the [native integration](https://flake.parts/options/nix-unit.html)
+
+If nix-unit succeeds you'r nixos evaluation should be mostly correct.
+
+!!! Tip
+    - Ensure most used 'settings' and variants are tested.
+    - Think about some important edge-cases your system should handle.
+
+### NixOS VM / Container Test
+
+!!! Warning "Early Vars & clanTest"
+    The testing system around vars is experimental
+
+    `clanTest` is still experimental and enables container virtualization by default.
+    This is still early and might have some limitations.
+
+Some minimal boilerplate is needed to use `clanTest`
+
+```nix
+nixosLib = import (inputs.nixpkgs + "/nixos/lib") { }

+[Mycelium](https://github.com/threefoldtech/mycelium) is an end-to-end encrypted IPv6 overlay network that spans the globe.
+
+## Features
+- Locality-aware routing: finds the shortest path between nodes.
+- All traffic is end-to-end encrypted.
+- Can route traffic via friend nodes and is location-aware.
+- Automatic rerouting if a physical link goes down.
+- IPv6 addresses are derived from private keys.
+- A simple, reliable message bus is implemented on top of Mycelium.
+- Supports multiple transports (QUIC, TCP, …). Hole punching for QUIC is in progress to enable true P2P connectivity behind NATs.
+- Designed for planetary-scale scalability; previous overlay networks reached practical limits, and Mycelium focuses on scaling.
+- Can run without a TUN device and be used solely as a reliable message bus.
+
+Example configuration below connects all your machines to the Mycelium network:
+```nix
+mycelium = {
+    roles.peer.tags.all = {};
+};
+```

 - Connect using a name that matches a cert principal (e.g., `server1.example.com`); wildcards are not allowed inside the certificate.
 - CA private key stays in `vars` (not deployed); only the CA public key is distributed.
 - Logins still require your user SSH keys on the server (passwords are disabled).

-## Usage
+This service configures Syncthing to continuously synchronize a folder peer-to-peer across your machines.
+
+Example configuration:
 
 ```nix
 {
-      instances.syncthing = {
-        roles.peer.tags.all = { };
-        roles.peer.settings.folders = {
-          documents = {
-            path = "~/syncthing/documents";
-          };
-        };
+  instances.syncthing = {
+    roles.peer.tags.all = { };
+    roles.peer.settings.folders = {
+      documents = {
+        path = "/home/youruser/syncthing/documents";
       };
+    };
+  };
 }
 ```
 
-Now the folder `~/syncthing/documents` will be shared and kept in sync with all your machines.
+Notes:
+- Each key under `folders` is a folder ID (an arbitrary identifier for Syncthing).
+- Prefer absolute paths (example shown). `~` may work in some environments but can be ambiguous in service contexts.
 
 
-## Documentation 
-Extensive documentation is available on the [Syncthing](https://docs.syncthing.net/) website.
+## Documentation
+See the official Syncthing docs: https://docs.syncthing.net/

+!!! Danger "Experimental"
+    This service is experimental and will change in the future.
+
+---
+
+This module is part of Clan's [networking interface](https://docs.clan.lol/guides/networking/networking/).
+
+Clan's networking module automatically manages connections across available network transports and falls back intelligently. When you run `clan ssh` or `clan machines update`, Clan attempts each configured network in priority order until a connection succeeds.
+
+The example below configures all your nixos machines to be reachable over the Tor network. By default, the `tor` module has the lowest priority among networks, as it's the slowest.
+
+```nix
+  inventory.instances = {
+        # Fallback: Secure connections via Tor
+        tor = {
+            roles.server.tags.nixos = { };
