A model can be confident a port should be 8686; a probe can report that 8686 answered, and
only the second is a fact. Detecting and repairing are also separate things to trust, so
the feature runs read-only until the write switch is turned on under it.
A bug stays open until the code changes and nothing here can close it; a finding closes
itself when the probe that proved the fault starts passing, so the two cannot share a
store. Acknowledging one is scoped to the value it was acknowledged at.
