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.

+- Decision class: task-scoped code/tests and scheduling-boundary clarification.
+- Delegator: the user who requested ACTIVITY-WP-0042 progress and explicitly
+  directed use of Emergent Security agent guidance in this conversation.
+- Scope: activity-core repository development in the build estate; no tenant
+  effect, production mutation, identity assignment, or recovery credential use.
+- Rules: C4 lowest sufficient scope; A2 proceed within the task; A6 code/tests;
+  C3/A5 no new capability or unowned responsibility; C2/C9 authority enforcement
+  stays with the platform executor; A8 this record and commit evidence.
+- Evidence: INTENT.md scheduling boundary, ACT-ADR-007 existing allowlist,
+  platform consent 0638c13b, offline adversarial contract tests.
+- Outcome: active offline implementation, T01 done; T05 and T03 retain their
+  specific unresolved requirements. The broader D2 decision is unchanged.
