  "description": "Counterparty internal credit-limit check: compares each counterparty's caller-supplied current exposure against its board-approved internal limit line (settlement, pre-settlement/PFE, or aggregate limit type), computes utilization percent and headroom, and flags each counterparty WITHIN_LIMIT, WARNING (above the caller-set soft-warning threshold, e.g. 90% of the limit), or BREACH (exposure exceeds the approved limit). This is a deterministic point-in-time check against internally governed limit lines -- distinct from the Basel/Reg-YY regulatory single-counterparty threshold check (art-425) -- and is NOT a real-time exposure monitor: no live feed, no intraday polling, no scheduled job. Not X: use art-425 for the Basel III / Regulation YY 25%/15%-of-Tier-1 regulatory large-exposures limit; use this node for internal (board- or risk-committee-approved) counterparty limit-line governance.",
