Reviews and grade of the Problem 501 reconstructions

../

ch_counterexample_reconstruction_review: Focused refutation review of the CH counterexample reconstruction against Glazer Section 6 and Lee Appendix A: the statement is faithful and the reconstructed argument is sound, with one required correction (a boundary quantifier in the iteration sentence), one suggestion and two notes.

glazer_lemma_2_1_reconstruction_review: Focused refutation review of the Lemma 2.1 reconstruction: the statement is faithful to the source and the argument is sound; no required corrections, one suggested label and two notes.

glazer_lemma_2_2_reconstruction_review: Fresh-context refutation review of the Lemma 2.2 reconstruction: source fidelity faithful, the reconstructed argument sound, zero required corrections, one suggested label and three notes.

glazer_lemma_4_1_reconstruction_review: Fresh-context refutation review of the Lemma 4.1 (Borel reading) reconstruction as of 2026-09-28T05:03:27Z: source fidelity faithful and the argument sound, with no required corrections, two suggested ones and four notes.

glazer_lemma_4_3_reconstruction_review: Finds the reconstruction of Glazer's Lemma 4.3 faithful with corrections and its argument sound; one required correction, to the Boundary paragraph's claim that the supports in Proposition 4.4 are pairwise distinct.

glazer_lemma_4_5_reconstruction_review: Source fidelity faithful with corrections, and the argument defective at one transfer step under its main-line reading; one required correction, two suggested corrections and one note.

glazer_proposition_4_4_reconstruction_review: Faithful with corrections: the statement matches the source's Proposition 4.4 and the reconstructed argument is sound; one required correction, a false and unneeded distinctness sentence in the proof.

glazer_theorem_1_1_reconstruction_review: Refutation-failed: the page states Theorem 1.1 and Corollary 1.2 as the source does, and its assembly from Theorems 3.2 and 5.1 and the CH counterexample is sound; zero required corrections, one suggested rewording and three notes.

glazer_theorem_3_2_reconstruction_review: Source fidelity faithful with corrections and the reconstructed argument sound: one required correction, a remark that misstates which clauses of the certificate's condition (P1) the proof uses.

glazer_theorem_5_1_reconstruction_review: Faithful to the source and sound as reconstructed: zero required corrections, two suggested label and import additions, and three notes.

grade: Grades the thirteen focused reviews of the Problem 501 reconstruction pages as of 2026-09-28T05:03:27Z (all pass), adjudicates every finding against the two held notes, and accepts seven corrections C1--C7; no tier.

lee_lemma_2_1_reconstruction_review: Focused refutation review of the Lemma 2.1 reconstruction as of 2026-09-28T05:03:27Z: source fidelity faithful and the reconstructed argument sound, with zero required corrections, three suggested and four notes.

lee_lemma_3_1_reconstruction_review: Focused refutation review of the Lemma 3.1 reconstruction as of 2026-09-28T05:03:27Z: source fidelity faithful and the reconstructed argument sound, with no required corrections, one suggested correction and two notes.

lee_theorem_1_1_reconstruction_review: Refutation review of the Lee Theorem 1.1 and Corollary 1.2 reconstruction as of 2026-09-28T05:03:27Z: source fidelity faithful and the reconstructed argument sound, with zero required corrections, one suggested label for the supplied corollary derivation and four notes.

These records are the independent focused reviews of the reconstruction pages in the Problem 501 research folder as of 2026-09-28T05:03:27Z, one per page, each a fresh-context refutation review of that page against the held notes on the library cards [[../library/set_theory/glazer_2026_erdos_problem_501_after_adding_random_reals/_index|Glazer (2026)]] and [[../library/set_theory/lee_2026_relative_independence_erdos_problem_501/_index|Lee (2026)]], and one distinct grade, [[research/erdos_501/evidence/verify/grade|the grade]], which records pass or void for every report, adjudicates each finding, lists the accepted corrections C1--C7 and states the graded verdict per page. They are focused reviews under docs/verification.md "Review and acceptance": each retains its stated scope, carries no tier, and changes no status.
