- Auth: none declared

Validates catastrophe bond trigger term structure and computes layer arithmetic: attachment/exhaustion point ordering, pro-rata layer penetration factor, payout amount, and layer position (BELOW_ATTACHMENT / WITHIN_LAYER / ABOVE_EXHAUSTION). 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.
