Use when building or fixing behavior in the DPF codebase and you want the test to define done before the code exists. Red-green-refactor, DPF-governed: for a bug/regression, write the failing test that reproduces it FIRST (generalizes security-fix-needs-regression-test-first); prove green functionally (a structural pass is not verification); never report a test passing you did not run. The DPF-native test-first discipline; replaces the retired upstream superpowers test-driven-development dependency.
