Evidence

26 attacks written before any change on 2026-11-02, each against one promise.

Run	Engine	Held	Counts?	Note
1	1.0.0	17/26	no	harness bug: broker.mint called without its grants argument; 6 mint cases crashed or passed for the wrong reason. Not a measurement.
2	1.0.0	19/26	yes	harness fixed, engine unchanged: the reported blind result
3	1.1.0	26/26	yes	after the fixes; the set is now a tuning set

Run 1 is shown because it happened: our own test harness called BROKER wrongly, so it measured nothing. We fixed only the harness and ran again.

Run 2, every row (engine 1.0.0, unchanged)
