Start on the public path. Search by package name, source system, or business concept. On web, the detail page exposes origin, preview, and installability before you move into README or graph.
Caution: if a package is marked Preview only, treat it as a structure review path, not a rawctx download candidate.
python3 -m pip install --upgrade rawctx
rawctx search "shopify revenue" --sort downloads
