The history of frame-hands (~/Desktop/Projects/frame-hands on the Frame), filtered to what moves: the camera broker (camd/), the tracker and its offline tools (trackd/), the shared file layouts (include/), the ncnn models, the analysis tools, and the calibration and model helpers they import from the Python prototype. The reverse-engineering notes, probes, camprobe, and the rest of the prototype stay in frame-hands. Unchanged here: the renames to ft- names and Frametop paths follow.
