- Methodology: scoring mathematics (2PL MAP, Fisher SE, BT MM + SE, composite
  formulas), item lifecycle & bank hygiene, full judge protocol, known
  limitations, versioning/audit section, contact block
- New /privacy and /terms pages (contact: Simon-Pierre Boucher,
  contact@spboucher.ai), footer links
- Efficiency frontier + hero stats now poll live (/api/v1/efficiency)
- Rankings display current INDEX_VERSION only (old runs remain as
  immutable audit history)

IRT 2PL + Bradley-Terry scoring over 12 domains with dynamically generated
items: hardened math/reasoning/code/knowledge/multilingual/instruction,
home-made simulated agentic (+context-load) and terminal benches, SVG logo
duels (3-judge cross-provider panel), vision OCR. Robust extraction cascade,
parallel evaluation lanes with live-updating leaderboard, per-model full
transparency pages, public API v1, detailed methodology with references.
