Exclude billing fields from full-row Midjourney updates.

RelayMidjourneyNotify uses Save, and UpdateWithStatus writes Select("*"). A stale task loaded before RefundMidjourneyQuota can restore cleared quota, token_id, and billing_channel_id, enabling a duplicate refund. Exclude billing fields from status and notification updates, or add a version/CAS guard to every full-row writer.

The preparation-stage error is logged as a consumption error in both Midjourney handlers. PrepareMidjourneyTaskBilling only validates inputs and sets in-memory billing markers; it never charges quota. Both call sites reuse the settlement wording, which misdirects operator triage.

  • relay/mjproxy_handler.go#L260-L262: change the message in RelaySwapFace to name the preparation stage, for example "error preparing Midjourney billing".
  • relay/mjproxy_handler.go#L622-L624: apply the same message change in RelayMidjourneySubmit.
