Same cached LiDAR-only poses, data, block split, clock/scale nuisance settings, no priors, 0.1 degree observability ceiling, control threshold and holdout limits. This changes the statistical weighting and must not be interpreted as new evidence merely because a reported uncertainty changes. No new SOTA claim.",
