int_lap_residual_decomposed_qualifying

One row per qualifying lap.

Part of the Residual family.

One row per qualifying lap. 7-term decomposition mirroring int_lap_residual_decomposed but with qualifying-specific coefficients (near-zero fuel, cliff-suppressed compound degradation, quali-mode car pace). Grain: lap_id. Enables quali-vs-race skill comparison. Qualifying-session scoped: all inputs are qualifying session data or pre-fitted parameters (e.g., compound seed, constructor pace, segment median baseline). No race-day data is read.

Columns

Column	Type	Nullable	Tests	Description
lap_id		Yes	not_null, unique	PK, FK to stg_laps_qualifying
quali_driver_skill_residual_s		Yes	not_null	Driver pure quali skill residual purer single-lap pace signal than race. The identity closes in closed form, so this term absorbs whatever the baseline gets wrong; gating the lap set to push laps and taking the baseline per segment moved its mean absolute value from 7.04s (sd 13.13) to 0.76s (sd 1.33), against a real qualifying field spread of ~1-3s.
quali_segment		Yes	not_null	Q1/Q2/Q3 segment the lap was set in (FK to int_qualifying_segments).
base_track_pace_s		Yes		Field-pace baseline: the median push lap of this lap’s own segment, not of the whole session.
ratio_to_segment_best		Yes		lap_time_s / the best valid lap in the same segment.
track_unexplained_s		Yes		The track-evolution model’s own residual for the event, carried informationally and deliberately not part of the identity the same treatment as track_unexplained_s on the race side. Race-day proxy, like rubber_component_s and ambient_component_s here.
