Findings by check and signal

Checks run: duplicates, ordering, time_jumps, gaps, missing_values, out_of_range, flatline, spikes, power_curve, icing, units. Skipped: dst (UTC has no daylight saving time; set dst_zone to test a site zone); wind_direction (needs wind_dir or nacelle_dir); energy_counter (needs e_export_counter); energy_power (needs e_export and p_ac).

Provenance
- sensor_x_avg, _min, _max, _std to <signal>, <signal>__min, __max, __std (mapped sensors only)
- status_type_id to status_code; iec_category from the benchmark's status ids (0 normal, 1 derated, 2 idling, 3 service, 4 downtime, 5 other), an interpretation the benchmark does not publish as IEC categories
- Time stamps are anonymised and shifted per dataset: they carry no calendar information.
- farm C, event 55: one turbine's data with a training and a prediction section (x_train_test).
Findings describe the data, not the sensors: a long run of zeros is normal at night, a power far below the curve is normal during a stop. Thresholds are in QCConfig.
