+## v0.251.0 — Nothing decides by reading a Hungarian word (2026-09-17, R-553 + R-563)
+
+**MinAgent: 0.131.0** (unchanged). **No hub release needed.** Nothing a household reads changes: every
+Hungarian sentence is byte-identical, and the hub report is unchanged (pinned by a wire test).
+
+Five places branched on their own customer-facing copy. Localisation slice 2 translates exactly those
+words, and each one would then have taken the other branch, silently. Each now reads a signal set where
+the message is made — `internal/util.KindErrorf` builds the same bytes `fmt.Errorf` did while carrying a
+sentinel for `errors.Is`.
+
+| # | decision | read before | reads now |
+|---|---|---|---|
+| 1 | deploy HTTP status (`api.deployStatusFor`) | „kötelező", „memória", "does not exist", "already deployed" | `stacks.ErrRequiredField` / `ErrPathMissing` / `ErrNotEnoughMemory` (400), `ErrAlreadyDeployed` (409) |
+| 2 | off-site failure class (`ClassifyOffsiteFailure`) | „tárhelykeretet" | `backup.ErrOffsiteQuota` |
+| 3 | where a disk warning is shown (`web/alerts.go`) | „meghajtó"/„adattároló" in the warning | `monitor.WarnKindStorageNotSeparate`, carried in `HealthReport.WarningKinds` |
+| 4 | the stale „nothing selected" note (`offboxWarningDisplay`) | „nincs mentésre jelölt alkalmazás" in the PERSISTED text | `settings.OffboxTarget.LastWarningKind` = `backup.OffboxWarnNoAppsSelected` |
+| 5 | the remote-backup poll (`backups_remote.html`) | the displayed word „Fut" | `data-status="running"` on the status element (R-563) |
+
+- **The restic / ssh signatures in the classifier stay text matches on purpose** — that output is not
+  ours and is never translated. Listed as external in REPORT.md.
+- **Site 4 legacy:** a box upgraded to 0.251.0 still carries the old persisted text with no kind until
+  its next off-site run. The text test survives ONLY for `kind == ""`, with a removal row (R-570);
+  **slice 2 must not translate that producer before R-570 closes.**
+- **Site 5 is the one rendered byte that changed:** the `data-status` attribute (plus the poll line).
+  12 `backups_remote` fixtures re-captured; each differs from its predecessor by exactly those two
+  things, the other 94 are byte-identical. „Fut…" is now `{{T "backups_remote.fut"}}` (en „Running…"),
+  so the English page finally sees a running backup.
+- **The wire is untouched:** `internal/report/builder.go` copies Status/Issues/Warnings only;
+  `TestR553_HubReportWarningsAreUnchangedOnTheWire` pins the field set and the bytes.
+- New in REUSE.md §1: „Error kinds — never branch on a customer-facing sentence".
+
+**Red-proofs** (`felhom.eu/documentation/audits/r553-2026-09-17/redproofs.txt`): every site's pre-fix
+predicate restored and watched failing — deploy statuses fall to 500/400-for-anything, the translated
+quota error reads „ismeretlen okból", the translated disk warning jumps to the top banner, the stale
+note returns, and both languages lose the poll. The detector (`felhom.eu/scripts/i18n_inventory.py`)
+was re-run: template compares 1 → 0, and planted decoys prove it still convicts.
+
