suggestion is that the status is determined by a separate scoring

status at the end of game for this to be practical. If you disagree

Isn't an automated tournament where the players themselves determine
the final score preferable to one where an imperfect 3rd party is called
upon to resolve disputes?
If two programs disagree on the outcome, then they should be given a chance
to resolve their disagreement.
For a protocol, there's the question of what it is that the players should
agree on. Is it just the score, or the status of each string?
In any case, suppose both players are informed of the relevant details
of the disagreement, then play can proceed.
Now, only if both players pass immediately in the resumption,
is it necessary to force a result.
The most sensible thing to do then is, in my opinion,
to simply rule every string on the board as alive.
Compared to a 3rd party ruling, this has the advantage that both
players can be fully aware of the outcome,
and thus have no reason to complain about it. If either player is not happy
with this outcome, then they need only make a move in the resumption.
Preferably, this move should help to resolve the disagreement, but there's
no way to enforce such a thing.
If either side makes a move in the resumption, then it is as if the original
two consecutive passes never happened, and the programs can be given another
chance to agree at the next two consecutive passes.
I see no reason to limit the number of resumptions to only 1. It makes
the protocol more state-full, and leaves the players no discretion to
just resolve disagreement on one string while remaining
