+usc FCM-M5-001 delta: blocker-only snapshot v7 mechanically frozen at d1d13c241ac7d28cb1738764fd20de2b253c3f53a48a1009b4bfd2ba2397ebcd (84,193 B, 538 lines, UTF-8, exact authority EOF, no LF); rejected v6 c757a389… remains unchanged. 24 replacement spans are confined to Reviewer-B identity/mapping/padding blockers and direct internal alignment; no stale self-reference found. Fresh Reviewer A active on exact v7; Reviewer B held. PR #789 remains unchanged/green/zero durable provider review; #812 remains USC-only behind terminal #789; all implementation/live/disk holds remain.
