A Jetlink hand-back while engaged soft-disabled with Big Model Failed and
"Restart the car to retry", although the small model drives on and Jetlink
retries in seconds. Now nothing disengages: a Big Model Lost warning shows
for 5 s. A native chestnut's loss still raises Big Model Failed.
jetlink's swap events also refuse engaging for the second after a swap
(bigModelLoading) and hold the comm and localizer errors the swap's dropped
frame raises, as a chestnut load does. In control is the rule the swap
itself waits on (openpilot, or AOL armed or paused), and a gap in modeld's
runtime record holds the last state instead of reading as a switch.
The warning is a selfdrived alert, like aolAvailability: no new
OnroadEvent, so cereal and schema-policy.json are unchanged.
