OpenStrap research: reconstructing WHOOP 4.0 BLE data access

OpenStrap research reconstructs WHOOP 4.0 BLE framing, history synchronization and sensor-record decoding. Its Python research client can scan and connect to a band, stream heart rate and motion, drain history, decode frames and replay saved captures.
