Runs an exposure book -- residential real estate by LTV band, retail (QRRE transactor/revolver, other retail), corporate (ECRA external-rating or SCRA unrated), SME support factor, off-balance-sheet CCFs -- through a chosen rule_set (2023 original NPR or 2026 reproposal) and returns per-exposure risk weights, aggregate RWA, and a receipt. rule_status stays proposed until the rule finalizes.
