Use these checks for your self-hosted server after the approved upgrade. Start with the symptom observed during acceptance testing and keep the exact error and time. The cards are a diagnostic guide; they do not inspect your installation or apply changes.
Confirm recovery before continuing the rollout
Repeat the failed check after correcting its cause, then complete the pilot verification checklist. Record console access, the pilot device, a known historical report and a new activity record separately. Resume scheduled delivery only after reviewing its settings.
If validation still fails, pause further deployment and prepare the diagnostic support summary. If recovery is needed, follow the agreed restore procedure with a matching application and database set. Installing an older executable alone is not a verified rollback.
