Power Fx is a strongly typed formula language for expressing business logic. A typical host configures an engine, submits a formula for parsing and checking, then evaluates it and obtains a value; the interpreter adds mutable variables and formula recalculation. The repository also includes editor-protocol support and connectors for invoking external services and working with tabular data. The map follows the sampled engine, interpreter, connector, and language-server evidence; many domain capabilities are identified only by the file tree, so their internal links are omitted rather than inferred.
