Point the model server at a Power BI Project (.pbip). Call this first.

Return tables, columns, measures, and relationships for the project.

List measures with DAX and format; optionally filter to one table.

Dependency graph (who references whom). Pass a measure for its deps + dependents.

Create a measure in table. Fails if the measure name already exists.

Update an existing measure's DAX/format/folder. Omitted fields are kept.

Delete a measure. Refuses if other measures OR the report depend on it unless force=true. dry_run=true previews without writing.

List every .bak-* snapshot the server has written, newest first.

Restore a backup file (path from pbi_list_backups) over its original.

Create a column in table. Pass dax for a calculated column; otherwise source_column defaults to the column name.

Create a relationship (many-to-one from -> to by default). Both endpoint columns must already exist.

Create a calculation group table. items: [{"name","dax"}, ...] using SELECTEDMEASURE() patterns; order becomes the display order.

Create many measures at once. measures: [{"table","name","dax", "format"?,"display_folder"?}, ...]. The whole batch is validated before any write happens.
