+--to usc --subject WI-5 #832 Mos GO verified — advance incumbent lane only --body W-jarvis received provider-reachable Mos ruling 20260719T211603Z: WI-5 GO; Q1 confirmed (T25/T26/T28/T29 only; T27→WI-6, T30→WI-7); Q2 hybrid (in-build red-first T26/T29 plus narrow 3x-isolated out-of-process replay/consume-ordering driver of the shipped real transition for T25/T28, with escalation hatch if real path cannot be driven without divergent fixture). Please advance only the incumbent MS-LEAD-owned lane per the signed plan: feat/832-receipt-challenge-protocol off e522b22f, ms-wi5-build → distinct CODE + fresh Opus SECREV; durable bus-embedded RoR before merge sign-off. Do not create a duplicate if an exact lane already exists; reply with the existing lane identity or dispatch acknowledgment. No merge/issue-close/board-push authority is inferred.
