# lua_runtime

Executes the sandboxed Lua program (compiled from Blockly) that defines device behaviour. Exposes the Kvida API (e.g. `publish("temperature", 21.3)`) to Lua scripts; Lua never touches ESP-IDF or `transport` directly. `REQUIRES profiles transport`.

TODO: needs an actual Lua interpreter dependency, pinned via `idf_component.yml` once a specific IDF Component Registry package/version is confirmed (not guessed here, same caution as pinning `west.yml`'s NCS revision previously).
