The class banked 5 functions today (func_801457A4 x3 at the whale's end boundary,
func_80183830 x2 one region lower) so it deserved a sweep rather than a third
hand-derivation. It reads every splat yaml's _o0<letter> 'c' subsegs, takes the
START of the NEXT subseg as the boundary vaddr, and reports an open stub sitting
exactly there whose target carries the -O0 prologue tell.
RESULT: 141 binaries with an _o0 subseg, 288 boundaries examined, 0 candidates.
THE CLASS IS EXHAUSTED -- today's five were the last of it.
A sweep returning 0 must prove it CAN return non-zero, so that null is
negative-controlled: the 288 computed boundaries include 0x801457A4 in 138
binaries and 0x80183830 in exactly ov_SC03_118 + ov_SC03_119 -- i.e. it does find
the addresses it banked, they simply have no open stub any more.
Every rejected boundary is printed WITH ITS REASON and the denominator is printed
(R32): a sweep that reports only its hits cannot be told from one that scanned
nothing. It deliberately does not consult the family map -- rollout_o0 refuses this
recipe for a bookkeeping reason ('family with exemplar ... not found in the map'),
not a structural one, and is separately blind to any _o0 basename.
