Registry coverage is broader than the rating model. Unrated entries remain visible here but are excluded from Elo rankings and charts. Source-candidate intervals are claims awaiting identity review, not settled historical boundaries.

      How to read this

      A rating is an evidence-conditioned estimate, not a timeless verdict.

      New historical polities enter with a fresh prior. Tactical results, strategic results, conflict scale, stakes, and confidence affect updates separately; missing evidence widens uncertainty.
