description: "Recomputes the transfer fee a Token-2022 mint with the transfer-fee extension withholds and the net amount the recipient receives, given the fee schedule, the TransferChecked amount, the execution epoch and the amount a payment verifier credited, then reconciles the credited amount against that net: MATCH, OVER_CREDITED or UNDER_CREDITED with credited_minus_net reported. OVER_CREDITED with the fee as the difference reproduces the Kora GHSA-725g defect class, a facilitator crediting the pre-fee gross amount; the advisory's arithmetic is quoted only as its public text states it. All amounts are decimal strings computed in BigInt with 128-bit intermediates and no floats, porting the pinned Token-2022 clause arithmetic: ceiling(amount times basis points over 10,000) capped at maximum_fee, the newer schedule applying from its epoch on, and the informational minimal pre-fee inverse choosing the smaller amount. The output also records a declared-fee FeeMismatch for TransferCheckedWithFee, an EPOCH_SCHEDULE_DIVERGENCE when the verifier used a different schedule than the execution epoch, and an informational consumer view showing where the x402 SVM gross-amount exact-match path and the balance-delta net path disagree. Exclusions: no wallet addresses, no authorities, no account keys, no signatures, no live data."
