- The index says it will version the battery rather than quietly edit it; its table currently has no published grades.
Field notes
The proposed score is the weighted share of a battery completed to standard, with cost per full run shown beside it. Model profiles are described across nine domains and are meant to make no call where graded evidence is absent. The page lists three pilot-complete systems, but labels them not yet graded; the standard battery remains in construction.
