// R-252 — THE PAGE'S QUESTION AND THE RESOLVER'S ANSWER ARE THE SAME QUESTION.
//
// The restore page renders its "re-attach your drive" notice from HasRestoreDestination(); every
// restore refuses from offboxRestoreScratchDir(). If those two ever disagree the page either warns a
// box that would restore fine, or stays silent on one that cannot — and the second is R-252 exactly
// as the fifth walk met it. So this asserts the CONSEQUENCE (does the resolver refuse?) against the
// predicate the page renders from, on one fixture.
//
// RED-PROOF: make HasRestoreDestination return true unconditionally and the first block fails — the
// predicate claims a destination while the resolver refuses in the very next assertion.
