NEW MiCA Report — EU/EEA Authorization Logic — EU Authorized now strictly requires ESMA/NCA register confirmation from EU/EEA jurisdictions only (27 EU + IS/LI/NO). Non-EU regulated issuers (e.g. USDG/MAS Singapore) shown in separate Non-EU Regulated block. NAV-based instruments (USYC, USDY, BUIDL) classified as NAV Instrument — outside EMT/ART scope.

NEW MiCA Report — Readiness Matrix — Standardized Action Enum: KEEP / KEEP_MONITOR / ENHANCED_DD / LIMIT_NEW_USERS / DELIST_PLANNING. EU transition deadline: 30 June 2026. NAV instruments shown with NAV premium/discount instead of peg deviation.

NEW MiCA Report — Leaderboard Auth-Aware Scoring — Adjusted Score penalizes regulatory status: EU Authorized = no penalty · Non-EU Regulated = −15% · No EU Auth. Found = −25%. Labels: EU_AUTH / NO_EU_AUTH / NON_EU_REG / PENDING / NAV_INSTR.
