      "description": "Three independent computations a payment service provider runs over the same payee-verification surface. Step 1 scores eIDAS 2.0 credential acceptance readiness against the EUDI Wallet attestation profiles (art-13). Step 2 runs the verification-of-payee readiness diagnostic (art-548). Step 3 builds a hash-chained VoP session receipt over a declared attempt record (art-377). Each step computes from its own declared inputs; the order is analytical. EUDI Wallet member-state rollout is dated November 2026.",
