vendo doctor runs prints a stable code when it fails, like
E-WIRE-003. Each code below has its own page with the symptom, the cause,
and the fix.
Find yours by area below. Codes are never renumbered or reused, so an old code
always names the same failure.
Doctor reads what is on disk. It never starts your app and never calls it, so
every code that needed a live probe is retired. Retired codes stay listed here,
with their page, so an older report still resolves.
