Reviews and grade of the Problem 1171 reconstructions
grade: Distinct grader's record for the two focused reviews of the Lemma 2.1 and Theorem 3.1 reconstruction pages as they stood on 2026-09-28T05:03:27Z: both reports pass, one wording correction is accepted, both pages are graded faithful and sound, and no tier is assigned.
lemma_2_1_reconstruction_review: Refutation-charged review of the Lemma 2.1 reconstruction against the held Gao (2026) PDF: source fidelity faithful, argument sound, zero required corrections (one suggested wording change and one note).
theorem_3_1_reconstruction_review: Finds the Theorem 3.1 reconstruction faithful to the deposit at the stated pages and labels and its argument sound, with zero required corrections; one suggested labeling addition and one wording note are filed.
The records here are the independent focused reviews of each reconstruction page of the folder as it stood on 2026-09-28T05:03:27Z, one for the Lemma 2.1 page (review) and one for the Theorem 3.1 page (review), each by a reviewer in a fresh context under a refutation charge against the held PDF of Gao (2026), and one distinct grade by a grader distinct from the author and from both reviewers. Both reports pass; the grade accepts one wording correction (C1) to the lemma page and records both pages as faithful to the source and sound. These are focused reviews: they assign no tier, change no status, and leave the pages author-recorded.
