Determine which child prevents an OP dispute claim from standing
In a fault dispute game, adding several responses to one claim creates separate child subgames. Resolving a single favorable branch does not settle the parent.
Evaluate every child of the disputed claim
Identify the game address, claim index and parent index for each move. Reconstruct the parent-child relationships before interpreting outcomes. In the example, A lost its own dispute but B remained uncountered.
parent claim P
counterclaim A → successfully countered
counterclaim B → uncountered
An uncountered child is sufficient to counter P. A favorable result for P against A cannot cancel B. When following on-chain resolution, inspect completion of the child subgames and the rules for resolving the parent.
