-- VIOLET PASS9: per-factor VIOLET-vs-BLUE decision divergence monitor (v2).
-- One row per (asset, factor, event_seq).  Extends the V1 feed-divergence
-- idea to the factor plane (boost/beta/mc_scale/esof/ob/dc/posture etc.).
-- Columns match DecisionDivergenceRow field set (asserted by test).
-- Apply via apply_violet_ddl.py (one statement per HTTP POST).
