From plans/CatalogResearch.md: the solar research prompt was hand-written with 13 hand-picked fields and missed busbars, temperature coefficients, NMOT, system voltage, bypass diodes and datasheet/review depth. Generate the feature list from ETIM (EC001746 for PV) and the research prompt from the content type; borrow versions/labels/eval-per-version from prompt tools, the SharePoint way.
