How much money can this strategy actually carry? Returns capacity_computed | insufficient_input | no_capacity, with the capacity, a band, the binding constraint, the alpha after costs and a degradation curve. Capacity DECREASES as the assumed Sharpe falls. A missing adv_usd returns insufficient_input naming the field — the engine never guesses a liquidity figure. VALUE: How much money can this strategy actually carry? The answer every allocator asks and almost nobody can give, because the cost-to-alpha term needs a graded-strategy population to calibrate — and we hold one. Returns the capacity, the binding constraint, the alpha after costs and the degradation curve. The impact model is stated with its provenance and every parameter is overridable.
