Cat bonds outstanding $63.9B Q1 2026 (record $25.6B issuance 2025). Validates ISDA/IAIS trigger term constraints including attachment > 0 and exhaustion > attachment. Use in parametric-trigger-adjudication chain downstream of trigger evaluation, or standalone in cat-bond-trigger-validation chain. ZERO PII.",
