mart_degradation_history_envelope

Pre-aggregated historical stint envelope for the Degradation Simulator.

Part of the Marts family.

Pre-aggregated historical stint envelope for the Degradation Simulator. Grain: (circuit_id, era, compound, lap_in_stint). For each physical circuit × regulation era × compound, captures at every lap-in-stint the observed fuel-removed pace distribution (p10/p50/p90 of weight_corrected_lap_time) and the corresponding tyre-degradation-from-fresh band (the same minus the fresh-tyre anchor ref_green_pace_s). A compound=’_all’ rollup is emitted for fallback. Clean laps only (correction_weight = 1, not SC/VSC, not major outlier); cells with < 3 observations dropped.
