ui-drive.sh --rs485-devices fixed the roster for the whole boot, so no script could show the guest noticing a device go quiet. mbsim.py now serves a control socket (flare-edge --control); ui-drive.sh opens it next to the pty and hands its path to qmp.py drive (--rs485-control), whose new verb `rs485 silence|restore ADDR` sends one command and judges the reply. A run without a simulated bus records the step as fatal rather than a silent pass. Rig: unit 5 silenced reads online=false after 65 s in the status json, restored reads online=true after 64 s (flare-edge #184).

"""Offline tests for qmp.py's drive(): the QMP socket and the control channel
|
|
are faked, so this runs in well under two seconds with no VM.
|
|
|
|
What is worth pinning is the contract the docstring makes: every step gets a
|
|
results.jsonl row of ok / fail / fatal and the run CONTINUES, so one run
|
|
reports every broken expectation. The region verbs are where that was once
|
|
false (flare-edge issue #147): a reference whose box did not fit the
|
|
screendump raised out of drive() as a traceback, and a tolerance on the line
|
|
was never compared with the one the reference was captured under.
