"""
Verify grid resting-order fill sync without manual exchange testing.

Usage:
    cd backend_api_python
    python scripts/verify_grid_fill_sync.py          # contract tests only (no keys)
    python scripts/verify_grid_fill_sync.py --live   # also run testnet smoke if configured

Contract tests mock each exchange's get_order JSON — run these after every fix.
Live smoke requires .env.testnet.local — see tests/test_grid_exchange_fill_live.py
