Previously the edition-level branch of analytics.getProjectRankings (programId mode) pooled every juror's evaluations across every round into a single z-normalization context. A juror's mean and stddev are not stable across round types — quick intake screening produces a very different grading profile than a deep evaluation round, and mixing them yields a meaningless personal calibration. The rollup now groups points by roundId, computes one balance context per round, and aggregates per-project as the unweighted mean of the per-round balanced averages. roundId mode is unchanged.
