int_driver_race_skill_loro

De-confounded absolute equal-car skill, race grain (race_year, race_id, driver_id).

Part of the Skill family.

De-confounded absolute equal-car skill, race grain (race_year, race_id, driver_id). driver_skill_loro_s = P20 ceiling minus the LORO teammate baseline (used by the rating chain). driver_skill_field_s = median pace delta minus the de-biased constructor×race FE (int_constructor_car_fe.car_fe_s, car pace net of driver skill); used only by int_driver_circuit_era_affinity / Ghost Car Standings leaderboard, fixing the weak-teammate inflation confound. Negative = faster than field (both signals).

Columns

Column	Type	Nullable	Tests	Description
driver_race_skill_id		Yes	not_null, unique	Surrogate PK = hash(race_year, race_id, driver_id)
driver_id		Yes	not_null	Driver identifier
race_year		Yes	not_null	Race year (integer)
race_id		Yes	not_null	Race identifier (numeric)
driver_skill_loro_s		Yes		De-confounded equal-car skill, seconds. P20 of focal deltas minus LORO car baseline. Negative = faster. NULL when the driver is the only one with clean laps in his car that race (no equal-car reference). Used by the rating chain.
driver_skill_field_s		Yes		Field-anchored equal-car skill, seconds. Median pace delta minus the de-biased car term (int_constructor_car_fe.car_fe_s the constructor×race FE, car pace net of driver skill). The FE’s global driver anchor fixes the weak-teammate inflation confound that the old constructor-median term still leaked (that median absorbed the team’s driver skill, so subtracting it handed a weak driver’s slowness back as skill). NULL when the constructor×race FE is unidentified for this race. Used only by int_driver_circuit_era_affinity (Ghost Car Standings leaderboard).
clean_lap_count		Yes	not_null	Clean laps contributing to this driver-race estimate.
