PR #80's probe_reference_closure found the only unanswered references in the whole 19-file corpus: six code-4 soft pointers (the class the spec permits to dangle) from BLOCK_HEADER 0xA0B of sample_AC1032.dwg to erased INSERTs (0xD17/0xD18/0xD40/0xD41/0xD95/0xD96). Today that fact is only visible by running the probe. ObjectWalkSummary should carry a dangling-soft-pointer count (and ideally the referencing handle pairs) so the fact is a walk diagnostic and regression-testable, instead of probe-only.
Follow-up from PR #80.
