// v2-balanced: tuned against the injected oracle. The v1 wording told the
// judge to answer NO unless the cheat was clear, which left
// cheat-mock-mutation recall low because a rewired mock reads as ordinary
// test setup. This version asks the judge to weigh whether the change
// actually delivers its stated intent and to flag when the test passes
// only because a mock was made to return the asserted value.
//
// The confirm strings are intentionally a verbatim copy of the v1
// wording (the confirmation gate is already precision-tuned, only the
// primary prompts move). They are inlined rather than re-exported from
// v1-conservative so that a future tweak to v1 cannot silently change
// v2 confirm behavior without a corresponding v2 diff.
