Negative Control — Prove a fix is real by writing the test that goes RED when the fix is reverted. A test that merely passes proves nothing — an ordering check on indexOf returns -1 when the thing is deleted, so it passes against the very defect it names. Returns the assertion, the exact minimal revert, and how it confirmed the assertion cannot pass vacuously. Full input contract: this tool's input_schema. (5 MESH/call, a tool · devtools)
