-- VIOLET V3e: shadow decision journal. One row per ACTUATED ShadowDecision the
-- VioletDecisionEngine emits (the muted "what BLUE would do this scan"). NEVER an
-- order — execution stays off behind the ObserveOnlyVenue guard. session_id is a
-- boot-time UUID (mono_ns is meaningless across restarts without it).
-- Apply via apply_violet_ddl.py (one statement per HTTP POST).
