Detailed Description

Read-only proxy to access parameters needed by observable computations.

This proxy is meant to be used by the observable/business layer to query:

• SM parameters
• BSM parameters
• Wilson coefficients
• Flavor/decay/observable blocks

The proxy enforces an allow-list of parameter types (see ALLOWED).

Special behavior for Wilson parameters:

• If the parameter does not exist, returns a default-constructed scalar_t instead of raising (this is convenient when some Wilson blocks are optional, group-dependent, or not produced for a given backend).

Two access styles are provided:

• by ParamId (typed access, recommended)
• by (block, LhaID) (legacy/low-level access)

Typical usage:

ObsParameterProxy sm(ParameterType::SM);
double mt = sm("MASS", 6); // depending on your LhaID overloads
 
ObsParameterProxy wil(ParameterType::WILSON);
scalar_t c7 = wil("B_MATCHING", LhaID(...));
