Part of the [Residual](/transform/families/residual) family. > For the conceptual foundation, read [Int Lap Residual Decomposed](/decomposition/seven-term-identity). One row per lap. 7-term decomposition: splits lap time into fuel penalty, compound degradation, track rubber evolution, ambient weather, constructor car pace, dirty-air tax, and driver skill residual. Identity: pace\_delta\_s = fuel\_component\_s + compound\_component\_s + rubber\_component\_s + ambient\_component\_s + constructor\_component\_s + dirty\_air\_tax\_s + driver\_skill\_residual\_s. Driver skill residual = what remains after removing all physics/car/strategy factors. ## Lineage ```mermaid theme={null} flowchart LR int_circuit_x_constructor_interaction --> int_lap_residual_decomposed int_compound_cliff_predicted --> int_lap_residual_decomposed int_constructor_structural_pace --> int_lap_residual_decomposed int_dirty_air_tax_component --> int_lap_residual_decomposed int_event_corrections --> int_lap_residual_decomposed int_field_pace_curve --> int_lap_residual_decomposed int_lap_fuel_state --> int_lap_residual_decomposed int_stint_geometry --> int_lap_residual_decomposed int_track_evolution --> int_lap_residual_decomposed stg_laps --> int_lap_residual_decomposed int_lap_residual_decomposed --> fct_cliff_prediction_features int_lap_residual_decomposed --> fct_driver_skill_features int_lap_residual_decomposed --> fct_ghost_car_pace int_lap_residual_decomposed --> fct_lap_residuals int_lap_residual_decomposed --> fct_stint_features int_lap_residual_decomposed --> int_constructor_deg_sensitivity int_lap_residual_decomposed --> int_lap_anomaly_flags int_lap_residual_decomposed --> int_lap_residual_stint_detrend int_lap_residual_decomposed --> int_qualifying_decomposed int_lap_residual_decomposed --> int_sector_residual_decomposed int_lap_residual_decomposed --> int_tyre_surface_vs_bulk_decoupling int_lap_residual_decomposed --> mart_degradation_history_envelope style int_lap_residual_decomposed fill:#e40404,stroke:#e40404,color:#fff ``` ## Overview | Property | Value | | ----------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Layer | `intermediate` | | Family | [Residual](/transform/families/residual) | | Contract enforced | No | | Upstream | [`int_field_pace_curve`](./int_field_pace_curve), [`int_lap_fuel_state`](./int_lap_fuel_state), [`int_stint_geometry`](./int_stint_geometry), [`stg_laps`](../stg/stg_laps), [`int_compound_cliff_predicted`](./int_compound_cliff_predicted), [`int_track_evolution`](./int_track_evolution), [`int_constructor_structural_pace`](./int_constructor_structural_pace), [`int_circuit_x_constructor_interaction`](./int_circuit_x_constructor_interaction), [`int_dirty_air_tax_component`](./int_dirty_air_tax_component), [`int_event_corrections`](./int_event_corrections) | **12 tests** [guard](/transform/ci/overview) this model - 7 generic, 5 singular. ## Columns | Column | Type | Nullable | Tests | Description | | ------------------------- | ---- | -------- | -------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `lap_id` | | Yes | [`not_null`](/transform/ci/structural), [`unique`](/transform/ci/structural) | Foreign key to stg\_laps | | `valid_lap_in_stint` | | Yes | | Passed through from int\_stint\_geometry. Ordinal among valid laps only within the stint; consumers should key position/length logic off this, not lap\_in\_stint. | | `stint_length_valid` | | Yes | | Passed through from int\_stint\_geometry. Count of valid laps in the stint. | | `constructor_component_s` | | Yes | [`not_null`](/transform/ci/structural) | Constructor structural pace in seconds from int\_constructor\_structural\_pace. Positive = slower than field. | | `dirty_air_tax_s` | | Yes | [`not_null`](/transform/ci/structural), [`expect_column_values_to_be_between`](/transform/ci/range-and-domain) | Per-lap dirty-air slowdown cost from int\_dirty\_air\_tax\_component. Non-negative seconds. Zero when not in dirty air. Subtracted into driver\_skill\_residual\_s, so θ\_air sits inside the ML label: this column feeds DEGRADATION\_TARGET and CLIFF\_TARGET. 08q (2026-09-21) moved θ\_air from an unfitted 0.5 literal to the fitted +0.1310 s/lap, which changes this component on the \~23% of panel laps that are dirty-air laps and requires a target rebuild plus a model version bump. | | `driver_skill_residual_s` | | Yes | [`not_null`](/transform/ci/structural) | Residual after all 7 physics components. Cleaned of dirty-air signal vs pre-causal-decomposition. Positive = slower than field baseline after all adjustments. | | `total_explained_s` | | Yes | [`not_null`](/transform/ci/structural) | Sum of all 7 components (fuel + compound + rubber + ambient + constructor + dirty\_air\_tax) |
