-- 6. UPDATE schema_reference.sql sync comment
-- ────────────────────────────────────────────────────────────
-- After running this migration, all 7 tables are fully defined:

--   2. entries          (watchlist & manual positions)
--   3. trade_history    (completed trade ledger)

--   5. trade_profiles   (strategy profiles with rule config)
--   6. bot_config       (global config key-value store)
--   7. dynamic_config   (runtime config overrides)
