Reindexes a flat [Landmark] list in Halpe-26 order into a named Landmarks2d.Human26 record with full-body and foot fields. A Maybe<Landmarks2d.Human26> sink yields an empty result on a short list; either arm always emits exactly one output.
A Halpe-26 estimator's keypoints are named, then drawn back onto the frame by visualize for a full-body overlay including the feet.
The named record feeds a gait or biomechanics metric that reads the foot joints by field, such as a stride or heel-strike measure.
Landmarks2d.Human26 consumer the incoming input list must carry at least 26 points; a shorter list is a hard contract breach that stops the deployment. Connect a Maybe<Landmarks2d.Human26> consumer instead to tolerate short lists: a valid list yields the record and a short list yields an empty result, and every input always produces exactly one output.input are dropped silently.Automated release
