What It Is
MotionSense smartphone accelerometer magnitude on stairs. 50 Hz; asymmetric step impulses, larger vertical excursions than walking.
Interpretation
Standard analysis sees: time-irreversible (sharp rises, slow decay). The atlas detects no named structure beyond this. It sits beside Accel Walk in the atlas (standard-bank rank 75) — a neighbor conventional features miss.

What the atlas adds
Nothing beyond the standard reading — this source’s structure is already captured by standard features; the atlas adds no named residual.
