CALCULATE evaluation order
summary
Shows exactly how CALCULATE evaluates filters: filters and modifiers are evaluated first (context transition happens on expanded tables), then the expression runs, so nested CALCULATEs and ALL / REMOVEFILTERS change outcome by ordering. Introduces a visual power Matrix to trace lineage, blocking semantics, and why filtering one column is faster. Demonstrates differences between regular filters, KEEPFILTERS, and model modifiers, and publishes runnable examples on GitHub covering surprising nested-order behaviors.
