Recomputes the NY Fed Treasury Market Practices Group fails-charge claim a buyer presents to a failing seller on a UST, agency, or agency-MBS settlement fail: charge = max(0, 3% minus the caller-declared reference rate) / 360 x par amount x days failed, per the published trading practice (2016 revision). Accepts a batch of fails in one pass, each with its own par amount, reference rate, and day count, and diffs the recomputed charge against a caller-declared claimed amount within a caller-declared tolerance -- never a default. A fail with no claimed amount contributes an INDETERMINATE line rather than a silent pass. Overall verdict DIVERGES if any fail's recomputed charge falls outside tolerance of its claimed amount; INDETERMINATE if every fail is within tolerance or unclaimed but at least one has no claimed amount to diff, or if the tolerance itself, or every fail, is absent; MATCHES only when every fail carries a claimed amount and every one agrees within tolerance. Par and claimed amounts are integer minor units, so the arithmetic is exact; recomputed charges round to the nearest minor unit. Performs arithmetic only over caller-declared par amounts, reference rates, day counts, and claimed amounts -- does not source, derive, or independently verify fail status, par amounts, or reference rates from any feed, and makes no TMPG/NY Fed endorsement claim. Clause: NY Fed TMPG fails-charge trading practice (2016 revision); confirm current text at newyorkfed.org before relying on a computed figure for a live claim.
