Operator rulings 2026-10-12, 09 §3 decisions 196, 204-207, 223, 227. MinAgent 0.131.0 unchanged.
R-255's sweep found one leak, fixed here: an optional-config secret_input was rendered into its
settings page; it is now revealed on demand. Hungarian parity fixtures re-captured once for R-562.

Saving the notifications form with a blank email box while events are enabled
wiped the customer's hub-side alert address (SyncPreferences pushed empty) —
the 2026-07-15 demo incident. settingsNotificationsHandler now refuses that
save before SetNotificationPrefs + hub sync, re-renders a Hungarian error, and
repaints the submitted checkboxes. Empty email + zero events (clear-all) still
proceeds. Tests + red-proof (remove guard -> stored email wiped to empty).
