-- VIOLET PASS9: economics/observability — exactly-one-row-per-event sink.
-- Columns match EconomicsRow field set (asserted by test_violet_economics_sink).
-- ReplacingMergeTree keyed on (session_id, event_seq) so a re-emit collapses to
-- ONE row — the PINK duplicate-emission debt, paid down.
-- wait_for_async_insert=1 on the economics write path (set in the sink).
-- Apply via apply_violet_ddl.py (one statement per HTTP POST).
