      "description": "Evidence pack for a monthly NY Fed TMPG fails-charge claim cycle between two settlement counterparties. The pack has one computational stage: a batch recompute of the published fails-charge formula, charge equals the greater of zero or three percent minus the declared reference rate, divided by 360, times par amount, times days failed, diffed against each claimed amount within a caller-declared tolerance, with an overall verdict of MATCHES, DIVERGES, or INDETERMINATE and a matching verdict for every individual fail line. The pack's evidence value comes from running that one stage twice: the non-defaulting party presenting the claim computes it once, and the failing counterparty recomputes it independently over the identical declared inputs. Because the kernel is deterministic, two honest recomputations over the same inputs reach the identical execution hash, and each side can countersign a receipt of that recomputation under SPEC.md section 27.12, kernel-pinned and dated, with no relay and no shared registry between the two firms. The receipt is evidence that both parties independently recomputed and signed the same result. It does not state or imply that either party owes or agrees to the claim, that the matter is closed, or that a dispute over the underlying fail or its reference rate is foreclosed. Every input, the fails themselves, their par amounts, reference rates, days failed, and claimed amounts, is declared by the caller: the pack reads no clearing feed and no fails database. The NY Fed Treasury Market Practices Group's fails-charge trading practice (2016 revision) is cited as the dated market practice this evidence is usually gathered for, not as a standard the pack certifies against.",

Every fail line carries its own MATCHES, DIVERGES, or INDETERMINATE verdict, and the batch carries one overall verdict of the same three values. Only the resulting execution hash, not any editorial reading of it, is what the two sides countersign."
