What
The message list's one-time error reports and the permission-prompt bell debounce used module-level flags and timestamps; they now claim named keys on the per-host registry, so both are one-per-host rather than one-per-process.
Details
The bell uses a variant that re-fires when the value changes, keyed on the dialog's id.
