| Check | Status | Detail |
|---|---|---|
| Readiness | pass | see metrics.json |
| Sampling | measured | calibrated magnetometer 50 Hz effective over N=18007 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 -0.00143844 µT/s (-0.518012 µT over 0.0–360.1 s, N=18007) |
| Motion | pass | Gyro quiet/active split and motion-gate trips are both reported; they use distinct established thresholds. |
| Thermal | review | 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. |

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.
