Receiver diagnostic: 2048 fixed centers, 2 unsupported; 1507 complete windows meet airborne speed and IMU-time support.

Among those windows, adjacent differences flag 920 for turning; the trend point estimate flags 749. Median vertical speed exceeds 1 m/s in 201 windows.

Under reported marginal covariance and Gaussian errors, 0 trend intervals lie wholly within ±0.02°/s assuming temporal independence, versus 0 allowing arbitrary temporal correlation. Ambiguous intervals: 1434 and 1478, respectively.

Every sampled window.

Generated controls test the noise-free window trend, not arbitrary instantaneous motion. Receiver covariance and temporal assumptions are not observationally calibrated. A smoother point estimate does not establish steady flight or create eligible intervals.
