# Gateway Rewrite

This folder hosts the native ESP-IDF C++ rewrite of the Lua DALI gateway.

## Layout

- `apps/`: standard ESP-IDF applications for each firmware role.
	- `apps/gateway/main/Kconfig.projbuild`: project-visible gateway-role settings such as per-channel native/serial PHY selection, gateway ids, and pin mapping.
- `components/`: reusable components shared by all gateway applications.
	- `gateway_core/`: boot profile and top-level role bootstrap.
	- `dali/`: vendored ESP-IDF DALI HAL/backend reused from LuatOS.
	- `dali_domain/`: native DALI domain facade over `dali_cpp`.
	- `gateway_runtime/`: persistent runtime state, command queueing, and device info services.

## Current status

The native rewrite now wires a shared `gateway_core` bootstrap component, a multi-channel `dali_domain` wrapper over `dali_cpp`, a local vendored `dali` hardware backend from the LuatOS ESP-IDF port, and an initial `gateway_runtime` service that provides persistent settings, device info, Lua-compatible command framing helpers, and Lua-style query command deduplication. The gateway app exposes per-channel PHY selection through `main/Kconfig.projbuild`; each channel can be disabled, bound to the native DALI GPIO HAL, or bound to a UART1/UART2 serial PHY.
