description: "Per-ISIN/day CSDR cash-penalty recompute over a caller-declared open-fails set: selects the RTS asset-class/penalty-type daily rate (CSDR-RTS-2025-10, ESMA Final Report 13 Oct 2025), applies fail duration to a caller-supplied reference_price and quantity, credits partial settlement proportionally, and sums forward penalty exposure across the fails set. Fixes art-78-csdr-penalty-calculator's reachability defect -- art-78 priced off notional with no shipped pack able to feed it a differing reference_price; this node's schema instead requires a caller-supplied reference_price per fail. art-78 keeps its own identity and chain wiring unchanged. Supports an optional OCG Standard section 25 ocg-private-input@1 declaration (sha256-salted@1) for the ISIN and counterparty_id per fail, since a small ISIN/counterparty universe is enumerable by table lookup."
