Summary

• recover pre-submit input and React open-orders render races
• advance to a new round after explicitly accepted unconfirmed submissions
• wait instead of stopping on temporary startup, position-readiness, closable-quantity, order-capacity, and open-orders UI failures
• honor Binance 418/429 Retry-After backoff and treat 5xx submission outcomes as unconfirmed
• preserve hard stops for symbol/mode changes, Post Only changes, auth/permission and deterministic 4xx failures, unresolved native dialogs, and internal contract errors

Validation

• npm run build:binance-orderbook-trade
• npm test -- --test-reporter=dot (482 tests)
• npm run check:binance-orderbook-trade
