Detailed Description

Parametric sensitivities of a solved network, as optimizer input.

compute_model_sensitivities dispatches on what the model admits: open_sensitivities for an open network, closed_sensitivities for a closed one, and ctmc_sensitivities where the product-form derivatives do not apply and the chain has to be differentiated instead. Each returns a SensitivityData or nothing, so an unavailable sensitivity is absent rather than zero – a caller must not read "no derivative" as "the derivative is zero".
