int_lap_telemetry_aggregates

Per-lap telemetry features for the tyre-cliff model.

Part of the Physics family.

Per-lap telemetry features for the tyre-cliff model. One row per race lap. Powertrain aggregates (gear changes, rpm, full-throttle/DRS share, short-shift index) plus five within-stint-drift cliff signals (mid-corner speed loss, wheelspin proxy, throttle-trace decay, braking-point drift, lift-and-coast share), each measured vs the driver’s own early-stint baseline. Computed lap-internally from the ‘car’ telemetry channel; NULL where a lap has no telemetry (explicit missingness, carried as XGBoost native-NaN).
