Use the implemented IDs gcam_extract_market_sector, gcam_extract_technology_components, gcam_aggregate_provinces and gcam_plot_sector_change. Follow operations for exact dependencies, flat JSON parameters, dry-run/execution calls and artifacts.
Declare scenario, region, sector and year scope explicitly. Lists are comma-separated strings; the technology extractor has no method parameter. Review units and row coverage before passing a successful market CSV to aggregation or plotting. These are separate invocations with separate run IDs.
Aggregation excludes China/Global; its weighted prices do not establish complete national coverage. Plotting compares fixed years 2021/2035 and retains sector-cost filtering and weight fallback. Different years or query logic require reviewed manual adaptation.
Read detailed interpretation only when needed: price/quantity queries, technology queries, unit compatibility, price interpretation, technology components, worked unit-price reference. The method explains what the extracted measures mean.
