verify/: Independent focused reviews of each Problem 354 reconstruction page as of 2026-09-28T05:03:27Z, one report per page, and one distinct grade of the fourteen reports; no tier is assigned.


The entry point rechecks the two finite inputs that the folder's reconstructions consume as data. It uses the root Python environment and the shared Checker, reads no files and writes no output. Run it from the repository root:

sh
uv run --no-sync python wiki/research/erdos_354/evidence/main.py

The first input is the mask certificate of Appendix A (p. 17) of the Yu--Chen manuscript, transcribed from the PDF's text layer into the entry point: twelve digit templates, 125 nodes and 113 consecutive links. For every template, every third-digit pair and every integer pair q<p<2qq<p<2q, the check confirms what the Theorem 5.1 reconstruction draws from the table: the two constants of a node differ by exactly one and lie in [0,22][0,22]; the width of each node and the two overlaps between consecutive nodes are positive linear forms on the cone; and the chain runs from a lower form at most p+2qp+2q to an upper form at least 7p+6q7p+6q. Positivity on the cone is decided through p=2x+yp=2x+y, q=x+yq=x+y with x,y>0x,y>0, as the source describes. The check does not replay the source's own checker or its Lean kernel evaluation.

The second input is the pair of exact evaluations 518P(6/5)=−417455650659595^{18}P(6/5)=-41745565065959 and 1018P(13/10)=2858640142120639312910^{18}P(13/10)=28586401421206393129 that locate the Salem number of Geneson's Theorem 9 in (6/5,13/10)(6/5,13/10), with P(1)=−5P(1)=-5 and the reciprocity of PP used by the Corollary 12 reconstruction; the evaluations are in exact rational arithmetic. That PP is the minimal polynomial of a Salem number is imported from Dubickas and not checked here.

A passing run verifies the finite data only. It does not verify either source's argument and awards no tier.

The independent focused reviews of the reconstruction pages and their distinct grade are filed under the review records.
