R-553 + R-563 CLOSED (controller v0.251.0): evidence, 10 §9 rewritten, R-569..R-571, slice-2 dependency

- audits/r553-2026-09-17/: live before/after on demo-hp (CSRF redacted), the 409 refusal, the hub
  health block, red-proofs for all five sites, the site-5 fixture diff, gates.
- 10-localisation.md §9: the five decisions with what each reads now; the rule (a text signature may
  remain only where the text is not ours); the one legacy exception and its end date.
- Register: R-553 and R-563 closed to CLOSED-ITEMS; R-569 (four API handlers match English words),
  R-570 (the legacy stale-note fallback + the slice-2 fence), R-571 (classifier and alert placement
  documented nowhere). R-557 carries the R-570 dependency. 263 -> 264 open.
- STATUS, including the live probe that installed an app and was removed the same minute.

 # STATUS — what works, what's broken, what's next
 
+**Updated 2026-09-17 (late) — five hidden traps removed before the next language step.**
+
+> **Ready for a volunteer: yes, unchanged.** Nothing a household reads changed. The machine now knows
+> WHY something happened, instead of guessing from the Hungarian words on the screen.
+
+**Decisions I took.** None.
+
+**What I exercised, on the demo HP box.** Five places in the product used to make a decision by reading
+their own Hungarian words: which error code an install refusal gets, whether a cloud backup failed
+because the space ran out, where a disk warning is shown, whether an old note about "nothing selected"
+is still true, and whether a backup is running right now. Each one now reads a small hidden marker set
+where the message is written. The words are exactly the same, letter for letter. I checked the pages
+before and after the update: only live numbers differ, plus one new hidden marker on the backup page.
+
+**What broke, and whether it is fixed.**
+- **My mistake, fixed in two minutes:** my first live test of the install refusal picked an app that
+  did not need any field, so it INSTALLED that app on the demo box. I stopped it and removed it with
+  the empty folder it had just made, and rewrote the test to a safe one. Nothing else was touched.
+- The word "Fut" (running) on the cloud-backup page can finally be translated. Until today the page
+  read that word to know a backup was running, so the English page never noticed one.
+- Found, not fixed, filed: four more places do the same with English words; the classifier and the
+  warning rules are written down nowhere; and one old note on a not-yet-updated box still needs the
+  old word test until every box has made one cloud backup on the new version.
+
+**Rows.** Two closed, three opened. The register went from **263** to **264** open rows.
+
+**Needs you.** Nothing. The new version runs on the demo HP box only; the fleet floor is unchanged at
+0.250.0. If you do nothing: the other boxes keep the version they have, and nothing breaks.
