mcp-engine-dax-debugging

Use when a Power BI measure or query returns wrong values, unexpected blanks, inflated or duplicated totals, a total row that disagrees with its detail rows, a slicer that has no effect, or numbers that disagree with the source system. For slow-but-correct queries, use mcp-engine-dax-performance; for a whole-model assessment, use mcp-engine-model-quality.
