From 7b38f05eb246a388da3fd041719522c1af2d5fb6 Mon Sep 17 00:00:00 2001 From: tegwick Date: Sat, 3 Oct 2026 14:32:50 +0200 Subject: [PATCH] Implement offline recovery handoff within existing scheduling scope Apply the user-directed Emergent Security guidance to close the redundant role gate. Add closed request/receipt validation bound to run, cluster, implementation, mode and authority reference; preserve platform enforcement and operation admission gates.
