Initial synthetic fixture omitted actor+0xB00 roster-node back-reference, so no counter helper was reached. Second fixture reached the controller query with a missing controller pointer. Added the same inspected controller=-1 and 6B2010 eligibility stub used by prior correction harness. Both failures retained. Native18 source unchanged. The old ABI3 frame-publication harness was accidentally run against ABI5 and failed with an unmapped read; correct ABI5 harness passes12. No production pass inferred from those failures.
