Continuous ambient comparison

Compared with 81 ordinary 300-second phone windows from the same UTC day, the ambient mean change was -1048.3 nT.

Summary: CONTROL; -311.8 nT; complete with data-quality warning

Sensor context

Check Status Detail
Readiness pass see metrics.json
Sampling measured calibrated magnetometer 49.9999 Hz effective over N=15003 samples, 0 gaps
Warmup reported_unrecorded Phone-first warm-up occurred before Room recording; CSV t=0 is the first measurement sample.
Baseline Drift measured calibrated |B| drifts -0.0007882 µT/s (-0.236503 µT over 0.0–300.0 s, N=15003)
Motion review Gyro quiet/active split and motion-gate trips are both reported; they use distinct established thresholds.
Thermal pass see metrics.json
Ambient available Ambient context includes non-overlapping 300-second windows using the same 0–30 s versus 240–300 s outcome.
Rolling Anomaly measured Scores use feedback_meter level/drift_sigma. Both signs are treated symmetrically; ranked windows are descriptive.

Interpretation boundary

The primary result above is the fixed maglab-final-v1 comparison. Rolling windows describe how the run developed. Artifact masks annotate derived analysis only; no raw sample was changed or removed.
