+**2026-10-21 night (W25, controller `5776d54`, unreleased):** the off-site page's „Utolsó hiba" no longer shows the run's raw text to the household. It is built from the classifier's class and the run's own result (the failed apps by name, „the other apps are fine" when true, „the box tries again the next night" when a retry can help). The raw text — restic's included — stays verbatim in the log and, sanitised, in the operator's event; the „foreign error prints verbatim" rule below now holds for those two places only on this page.

 **[FACT] One exception, with an end date:** a box upgraded to 0.251.0 carries the OLD persisted note
 with no kind until its next off-site run, so `offboxWarningDisplay` keeps the substring test for
 `kind == ""` only. **Slice 2 (R-557) must not translate that producer until R-570 closes.**
