 # ESP32 Hacking TODO
 
 ## Firmware
-- [ ] WiFi probe request capture (PROBE_DATA via promiscuous mode)
 - [ ] On-device CSI processing (send metrics, not raw)
 - [ ] Deep sleep mode with wake-on-CSI-motion
 - [ ] Battery-optimized duty cycling
 
 ## Tools (esp-ctl)
 - [ ] Multi-sensor BLE correlation (zone tracking by source sensor)
-- [ ] Sensor discovery script (find all ESP32s on network via mDNS)
 
 ## Testing
 - [ ] Benchmark: CSI callback latency
