-These binaries match the deployed release on 192.168.0.223. The frontend includes the 4-digit CAPTCHA, inline countdown, and 140px image width.
+Both binary SHA-256 hashes match the installed executables on 192.168.0.223. The frontend was deployed and its service readiness and served JavaScript verified on 2026-09-08. The backend is the existing installed binary.
+
+The frontend adds persistent firmware upload progress, validation/apply/reboot status, automatic status polling after reconnection, and duplicate submission prevention. Completion is displayed only after the device reports success. Alt-clicking a tab close button keeps only the dashboard. Existing CAPTCHA behavior is retained.
+
+Validation: 4 firmware progress tests and 9 workspace tab tests passed; Linux ARM64 build passed. A full firmware flash was not performed for this UI release. The device's last inspected firmware journal still recorded the earlier minimum-version validation failure; this web deployment does not resolve firmware package compatibility.
