The only blocked check
Traffic has returned successfully; only the final count comparison and
finance fixture remain open. Finance needs one order that was captured,
partly refunded, and then exported after the cutover. Your picks reach
Ledger now; this page stays blocked until the agent runs them and saves the
result.
