RIG bits(0,4096)=0xff (in-page, legal)
RIG bits(0,8192)=0xff (size beyond page, unchecked)
RIG bits(4096,1)=0x0 (base beyond page -> phantom bit 8, visible to int consumers)
RIG bits(-512,1024)=0x3 (negative base/size -> shift UB, unguarded)
RIG set_valid(0,4608) on page w/ valid=0x0f -> m->valid=0xff (whole page 'valid', stale 0x41 tail now indistinguishable from validated data)
RIG tail fragment content still 0x41 (never zeroed: _vm_page_zero_valid only touches DEV_BSIZE boundaries)
