  Option Alpha publishes no HTTP/RFC 9457 API error catalog (no public REST
  API). It does document a registry of named platform errors, warnings, and
  failsafes that bots surface in automation logs when an automation cannot run
  or an order is rejected. Captured here as the provider's error reference.
