The recorder does not load the stock libk4a/libk4arecord. It dlopens a single custom libk4arecord_v2.so: the wrapper's MKV-writing sources linked to a pure-data shim (k4a_shim.cpp) instead of libk4a, so recording has no OrbbecSDK dependency. That target is FTF's own (wrapper/recordv2/), absent from the stock wrapper the Orin carried — so ship it and inject+build it, the same pattern as the recorder in the SDK examples tree. Idempotent; only added when missing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
