Broker logs after the 2026-09-30 restart show some boards (PV26B02BP01R01,
BSVSPR-26C20B-STD10R-2KCDPH) subscribing to vesper/{serial}/control rather
than control/command. The app ACL only allows publishing to control/command,
so the app can't command those boards until their firmware is updated.
Recorded so nobody widens the ACL by accident.
