Build or acquire each explicit earlier physical input; establish independent references and interfaces.
Make trials and accept only against the eventual caller specification; record uncertainty and rejected outputs.

What remains unresolved

Full inventory, required quantities, process settings, numerical demand and suitability remain open.
