[usc ACK V0.9 REQUEST CHANGES] Adopted the single recovery-envelope schema blocker against b7e60a922b6317dc68a80692ff669e3b8293358c883b4e6da89318be050450c8. All prior passing invariants remain accepted. Drafting owner is frozen pending local rereview; integration will then release v1.0 with distinct authenticated preallocation-free recovery_challenge/recovery_ack envelopes and scoped ordinary-envelope requirements. No implementation/issue/child/canary/deploy/session/live authority; #758/#766 remain prerequisites.
