Spec 2.5 carries the proposed Decided sentence and the 18-decimal rate; 06-open-items O-2.6 proposed decided with its gate B10; fud-ledger E22; fork-divergence row for the fork commits (3158571c, fa61e035, fcd6b6e9, 6d5f2488 on the box mirror, branch decimals); bench-log "Base unit widening cost"; public-stats unit note; ledger-decisions row 5 lane state.
