Repeatable post-deploy (and periodic) check that proves the books are consistent
against real data: per company, Trial Balance debits==credits, Balance Reconciliation
shows no drift, then Recalculate Balances and re-check. Includes the read-only
pre-deploy migration preview, the two pending migrations in order, account spot-checks
for the audit-touched accounts, and the inventory/sales-tax policy reminders.
