Detailed Description

High-level mutator for parameters used by the observable layer.

This class provides a unified interface to:

• set a parameter value absolutely (set),
• apply a shift relative to the current value (shift),
• switch the parameter mode (value / gaussian nuisance / flat scan, etc.) (change_mode).

It delegates the work to:

• ParameterSetter for absolute assignments
• ParameterShifter for relative shifts and mode changes

The identifier type is ParamId and the stored value type is scalar_t.

Typical usage:

ObsParameterMutator mut;
mut.set(ParamId{ParameterType::SM, "MASS", 5}, 4.18);
mut.shift(ParamId{ParameterType::SM, "MASS", 5}, 0.02);
mut.change_mode(ParamId{ParameterType::SM, "MASS", 5}, ParameterMode::GAUSSIAN);
