-- 017 — Intelligence tables (Session 6b).
--
--   historical_props      : ParlayAPI bulk archive (3.7M+ rows over time)
--   line_snapshots        : every SharpAPI pull stored for movement tracking
--   ref_profiles          : per-referee tendencies (foul rate, pace, bias)
--   coach_profiles        : per-coach system + pace preferences
--   game_ref_assignments  : game-day ref crew, with derived crew impact
--
-- All five tables are service-role-only — no RLS public read policies.
-- Internal services read/write via getSupabaseServiceClient(); public
-- consumers (Ledger, Pricing) read from grade_history / resolution_results.
