Errors and partial results

  • Treat non-2xx responses as API errors and log the response body for debugging
  • Log requestId and traceparent so SEC API support can trace the request
  • when confidence is low or freshness.status is stale/degraded, API the degradedReasons[] to the user verbatim so trust is not lost in the handoff
  • the score is deterministic given (inputs, methodologyVersion); a methodology bump is recorded in the persisted history table without overwriting prior rows
