io.technology_mapping

Load the technology-parameter map for cost sourcing.

Schema: see examples/technology-mapping.example.yaml.

build_technology_sources(spec)

Expand a raw technology entry to its {parameter: source} map.

A bare string applies to every standard parameter; a dict's overrides: win over its source: (or, absent source:, only overrides: parameters are sourced at all).
