A clinical Parkinson's-disease task — detecting the sudden, involuntary gait-freezing episodes characteristic of the disease from motion-sensor data — distinct from generic "gait detection." It surfaced first as a 2026-07-09 audit correction to [[claim-inertia-1-design-sweep-15-downstream-datasets]] (the original capture had genericized it) and now recurs as one of Inertia-1's three evaluation task families across every design-sweep claim-note, which is the recurrence that earns the hub.
