Build output goes to `build/` (excluded by `.gitignore`). External component `esp_csi_gain_ctrl` is fetched automatically to `managed_components/`.
### ESP-IDF v6.1 Workaround
The `esp_csi_gain_ctrl` component (v0.1.4) only ships prebuilt libraries up to ESP-IDF v6.0. On ESP-IDF v6.1+, the build fails with a missing `.a` file. Fix by symlinking:
```bash
cd managed_components/espressif__esp_csi_gain_ctrl
ln -s 6.0 6.1
```
This is needed after every `idf.py fullclean` or component re-fetch. The v6.0 library is ABI-compatible with v6.1.
