Research notes on every problem, and a library of the papers behind them. Built from the open erdos repository.
Updated
Review date: 10 September 2026. Primary reviewer: independent source compilation reviewer. Frozen state: the repository as it stood on 2026-09-10T05:48:43Z. The [[diophantine_problems/pipeline_math_2026_tiling_complement/evidence/verify/compilation_review|compilation review]] retains the verdict and independent derivations. This is a rendition of the original coverage receipt, not new source reading during filing.

These are exactly nine Markdown subjects, read as they stood on 2026-09-10T05:48:43Z.
The frozen consumer was read only for formulation and scope:
wiki/problems/diophantine_problems/E0477/_index.md as it stood on
2026-09-10T05:48:43Z.
Its variants and status-search claims are not review subjects.
The supplied scope note was titled NEXT_SOURCE_ACCOUNT_TRIAGE.md
(working storage; not retained). It is assignment context, not a
mathematical premise or required native artifact.
It pre-directed coordinate normalization, the shell repair and the family
convention. Two reported weakest-step selections were therefore pre-identified;
the reviewer independently derived their checks, not their selection.
Exposure ruling. Besides the unretained triage note that assessed the
reconstruction as complete and pre-named two of the three weakest steps, the
commissioned read set as it stood on 2026-09-10T05:48:43Z
carried the subject pages' own author-recorded standing (under
library/diophantine_problems/pipeline_math_2026_tiling_complement/:
_index.md lines 171–179, lemma_1_4.md 239–244, corollary_1_5.md 58–64,
proposition_1_6.md 229–233, lemma_1_7.md 96–101, proposition_1_8.md 70–77,
theorem_1_1.md 116–122) and public-acceptance text for the existence
conclusion (_index.md lines 56–75;
wiki/problems/diophantine_problems/E0477/_index.md line 7, lines 21–26 and 44–57); a
separately commissioned materiality grader acting in the corpus grader role
(model: Claude Fable 5.1) ruled on 18 September 2026 by the content test that
all three exposures are immaterial, because none states or implies the
premise-relative verdict asked of the reviewer and the review's reasoning rests
on independent rederivation corroborated by the subreview and the grader, so the
pass with named corrections stands unchanged.
Sources read and complete-page reading
All four PDF hashes agree with the supplied triage. No source was fetched.
| Edition read | Version | Complete pages read in text and rendered images | Mathematical depth |
|---|---|---|---|
| Pipeline-math manuscript | Six-page manuscript, 29 June 2026; upstream revision 99d916ff32a90e77c98eb004537ccda409262346; 334,096 bytes | All printed/PDF pp. 1–6 | All six essential same-source proofs independently checked. Theorem 1.2's unused general- case is not independently reviewed. Theorem 1.3's stronger whole-box restatement is not endorsed. The historical literature sentence and linked web acceptance history are not revalidated. |
| Corvaja-Zannier journal article | 2011 journal article, Bulletin de la Societe Mathematique de France 139(4), 437-454 | Cover and printed pp. 437, 438, 454 = PDF pp. 1, 2, 3, 19 | Definitions and recalled inequalities around equation (1.1), p. 438, claims checked; local normalizations independently checked. Pp. 437 and 454 supply identity and Brownawell-Masser reference [5]. The p. 454 proof fragment was visible/read only as page context, unused and not mathematically reviewed. |
| Heath-Brown journal article | 2009 journal version, Journal of Number Theory 129, 1579-1594, DOI 10.1016/j.jnt.2009.01.012 | Printed pp. 1579, 1580, 1589 = PDF pp. 1, 2, 11 | Introductory definitions and Theorem 2, claims checked. P. 1589 read for nonconstant-family interpretation and integer parameter context. Surrounding proof deductions and the full determinant argument are not independently reviewed. |
| Heath-Brown arXiv v1 | Distinct arXiv:0806.4330v1, 26 June 2008 | Printed/PDF pp. 1, 2, 10, 11 | Definition on p. 1 and Theorem 2 on p. 2 compared to the journal; pp. 10–11 read for curve and family context. The full proof is not independently reviewed, and v1 is not substituted as the accepted route's counting premise. |
There were no visual or access gaps on these selected pages. Rendered formulas were legible. Extraction corrupts some signs, membership symbols, and other glyphs, particularly in the manuscript; the rendered images controlled the mathematical reading. No conclusion rests on extracted formulas alone.
The unselected Corvaja-Zannier printed pp. 439–453 and unselected Heath-Brown pages were not read by the primary reviewer. The original Mason-Stothers and Brownawell-Masser proofs, the original sources inside Heath-Brown's determinant proof, historical Erdős-Graham pages, Price's manuscript, and stronger exponent/input variants were not opened. Unrelated external main theorems receive no review credit.
Source/ result correspondence and checked local additions
| Native proof | Manuscript locator | Local expansion or qualification included in review |
|---|---|---|
| Lemma 1.4 | pp. 2–4 | Rational-map extension; common-coordinate cancellation; geometric base-point exclusion; complete-line support and normalized nonconstancy; explicit height; rational constants; geometric image surjectivity and converse parametrizations. |
| Corollary 1.5 | p. 4 | Denominator argument; rational one-parameter curve meaning; signs and map extension. |
| Proposition 1.6 | pp. 4–5 | Exact journal theorem replaces whole-box restatement; fixed- shell summation and finite lower-box bound are local deductions absent from manuscript; family interpretation remains explicit. |
| Lemma 1.7 | pp. 5–6 | Empty obstruction set; new index distinctness; pairwise disjointness at the union; exact pair uniqueness. |
| Proposition 1.8 | p. 6 | Empty finite set; finite sum of constants; integer cutoff for exact count. |
| Theorem 1.1 | statement p. 1, final proof p. 6 | Full dependency composition and value/input uniqueness distinction. |
Supplementary independent interface reading
A separate fresh-context subreview read the frozen H/theorem_2.md and P/proposition_1_6.md, visually inspected journal pp. 1579-1580 and 1589 and v1 pp. 1–2 and 10-11, checked their extracted text, and verified the corresponding four hashes before and after reading. It returned refutation-failed for the source interface and fixed- shell-to-box deduction. It also checked the surrounding signed witness bound, nonsingularity, projection, and exponent while assuming Corollary 1.5. It did not review that corollary or the external determinant proof.
The primary review's derivation and verdict were reached and communicated before this subreview returned. Its findings agreed with the primary review and were compared only afterward. Seven supplementary renders were made, covering the listed journal and v1 pages. They are disposable reading aids, not required native artifacts. The subreview wrote no separate report or corpus file, fetched no source and ran no mathematical computation. This record retains the primary reviewer's attributed account of that supplementary coverage; it does not invent a separate retained subreview.
The four editions read are identified on their source cards: the manuscript, Corvaja-Zannier, Heath-Brown journal, and Heath-Brown v1. The links identify editions, not an instruction to fetch or substitute a different version.
Reproducible source inspection
System Poppler tools pdfinfo, pdftotext -layout and pdftoppm were used.
The 17 primary and seven supplementary rendered images are disposable,
regenerable reading aids. Their private locations are not mathematical
dependencies, and the native filing does not require those old pixels.
The following commands reproduce the primary reading scope from the repository root with copies of the four PDF editions named above at the paths assigned below; the reader supplies the copies. They create only a new disposable rendering directory and were not run during native filing:

For each of those four assigned paths, pdfinfo <source.pdf> identifies the
document, pdftotext -layout <source.pdf> - extracts all text, and
pdftotext -f <first> -l <last> -layout <source.pdf> - extracts a selected
PDF-page range. Substitute one assigned path and the page numbers
listed above. Every emitted selected page was opened during the original
reading. There is no mathematical checker or runtime-dependent certificate
to reproduce for this noncomputational argument.
Grader-supplied source context and limits
The distinct grade reports checking the native subject hashes, all four PDF identities and the substantive mathematics against those sources. Its findings add same-page support for the family convention: journal p. 1580, Theorem 1, calls the case “essentially different linear parameterizations.” This support is attributed to the grader, not to a new primary-reviewer finding or to the native filing author. It leaves the introductory definition's unprinted nonconstancy qualification explicit.
The original coverage receipt remains unchanged in working storage. This native rendition keeps every subject, version, selected page, exclusion, result correspondence and supplementary scope, while removing private paths and making rendering aids disposable. It is not a new reading.
Before the original native filing, all ten Markdown hashes and four actual PDF hashes again matched the recorded values. The frozen native subjects are named by path and date, 2026-09-10T05:48:43Z; the text they carried then is not retained as copies. The accepted transformation and subsequent standing reconciliation change the seven source pages' verification wording and generated navigation, not their statements or proofs. The PDF digests this record carried are not restated. Both external interfaces, the four editions read and the consumer remain unchanged.
The accepted native transformation and same-checkpoint standing reconciliation record the seven source pages' independent compilation review within the exact premise-relative scope identified by the review and grade. Attack selection was partly pre-directed; derivations were independently performed. External proofs, catalog status, public acceptance, other exponents or input variants, effectiveness and formal verification receive no additional coverage.
