The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

EgoKit exposes the same egocentric recording workflow across six heterogeneous host devices and produces locally stored video with a uniform log format; on XR headsets it additionally logs head pose and OpenXR-standard 26-joint hand tracking aligned to the video streams.

C2weakest assumption

That a single software layer plus low-cost accessories can reliably overcome the differing SDKs, raw camera access policies, and external-camera limitations of Android, iOS, smart glasses, and XR platforms without device-specific custom code or hardware.

C3one line summary

EgoKit is a new toolkit and accessory set that unifies egocentric video collection with wrist views across heterogeneous consumer devices using a consistent interface and log format.
