The one that could run the wrong program: guided setup accepted a name
another program already had. The duplicate check only compared names within
the form it was handed, and guided setup submits one program at a time, so
it never saw the others. Two programs sharing a label resolve to whichever
option comes first, so picking the second would have run the first one's
payload -- the exact failure the check exists to prevent, working correctly
in the bulk form and blind in the guided one. The taken set now includes
every other named program, excluding the slot being edited so confirming an
unchanged name doesn't reject itself.
The rest:
- The timeout screen's copy interpolates the same counters as the other two
but was shown without placeholders, so it rendered literal braces.
- The probe reports whatever payload is loaded, while observe() declines one
whose slot the device doesn't advertise. Guided setup could reach the name
form for such a slot, take a name, and silently discard it -- there is no
record to hang it on and no payload to replay. It now waits instead.
- The prefilled Download course came from the raw candidate list while the
dropdown filters to courses the appliance still offers, so a stale
candidate prefilled a value the selector rejects and the form failed
validation on something the user never chose.
