Detailed Description

Statistical-layer port for read-only access to parameters and observable entries.

This interface defines the read API used by the statistics module to access:

• generic model parameters through ParamId,
• typed parameters through (block, LhaID),
• observable entries through ObservableId,
• binned observable entries through BinnedObservableId,
• and the underlying Parameter objects when direct metadata access is needed.

The proxy is intentionally read-only: it is meant for likelihood construction, covariance handling, pulls / nuisance inspection, and statistical post-processing, without exposing mutation logic.

The returned quantity depends on DataType:

• DataType::VALUE : central value
• DataType::STD_STAT : statistical uncertainty
• DataType::STD_SYST : systematic uncertainty
• DataType::STD_COMBINED : quadratic combination of uncertainties

Concrete implementations are typically backed by ParameterProvider and the Parameters singleton infrastructure.
