# Test Coverage Kernel

> Load the surface catalog for a unit, walk the dimension-by-lens grid, derive the required-uncovered surfaces, prioritize them by risk, select a mode-matched technique and invariant per surface, author the test, issue an evidence verdict, ledger the state, and terminate only when no required surface remains unknown.
