# YANG Compiler

Transforms device-agnostic YANG site configuration into vendor-specific payloads.

## Pipeline
1. `sovereign-sdwan.yang` defines the schema
2. Per-site XML instance data (e.g., `homelab.xml`)
3. Compiler validates and produces vendor payloads
4. Vendor targets: FortiOS REST, VyOS NETCONF, UniFi API

## Usage
```bash
python3 -m compiler.compile --site-config site-config/homelab.xml --output-format json
```

## Adding a Vendor
Create a new `to_<vendor>.py` module in `yang/compiler/` implementing `compile_zones()`.
