Detailed Description

Statistical-layer port for retrieving leaf parameter sources.

This interface exposes a statistics-oriented view over the parameter dependency graph. Its main responsibility is to resolve a set of input parameters down to their ultimate “leaf” sources, i.e. the parameters that do not themselves depend on other parameters or dependent blocks.

It is intended for the statistics / sensitivity / dependency-analysis layer, where one often wants to answer questions such as:

• “Which fundamental inputs does this observable depend on?”
• “What are the root nuisance or model parameters behind this derived quantity?”

Concrete implementations typically delegate this work to a lower-level provider that walks:

• parameter-level dependencies,
• block-level dependencies, until only leaf parameters remain.

Typical usage:

std::shared_ptr<IStatSourcesProxy> proxy = std::make_shared<StatParamSourcesProxy>();
 
std::unordered_set<ParamId> seeds = {
    ParamId{ParameterType::OBSERVABLE, "FOBS", some_id}
};
 
auto leaves = proxy->get_all_leaf_sources(seeds);
