+AI Agent result capture release verifier preflight gate snapshot.
+
+Loads the latest committed P2-136 release verifier preflight gate.
+This module validates committed evidence only; it never authorizes owner
+release, approves maintenance windows, confirms rollback owners, passes
+release authorization, releases live apply, applies writers, writes receipts,
+writes result captures, writes learning records, updates PlayBook trust, writes
+reviewer / Gateway queues, sends Telegram messages, reads secrets, or performs
+destructive operations.
