Reverse-engineering writeup and tooling for the Elite 10 Gen 2 BLE head
tracking. The GATT interface is fully mapped; the orientation service
(20231219-1730-...) is gated behind Google Fast Pair authentication and
most likely never crosses GATT to a host (the buds spatialise on-device).

Includes the staged RE tools, an Android btsnoop parser, an OSC bridge
skeleton (jabra_osc.py), and the full protocol, capture, and resume-plan
docs.
