# arXiv fulltext archive — prose partition (sphinx lane, 2026-10-25)
|
||||
|
||||
## What this is
|
||||
|
||||
A deterministic prose/code partition for the archive lane's arXiv fulltext
|
||||
pipeline, plus the lane gate that runs it.
|
||||
|
||||
## Why it exists
|
||||
|
||||
`arxiv_fulltext.py` converts arXiv HTML/PDF into markdown and publishes a
|
||||
manifest with SHA-256 digests. Its tests assert on STRUCTURE — headings,
|
||||
references, captions, digests. None of them asserts the property the archive
|
||||
exists to preserve: that the published `paper.md` is the paper's **prose**, and
|
||||
not a document with code injected into it. A tampered `paper.md` whose digests
|
||||
were recomputed would pass every pre-existing check.
|
||||
|
||||
`prose.py` is that missing assertion.
|
||||
|
||||
## Files
|
||||
|
||||
| file | role |
|
||||
|---|---|
|
||||
| `prose.py` | the partition: `fence_blocks`, `code_blocks`, `prose_stats`, `is_prose_document`, `find_injected_code` |
|
||||
| `test_prose.py` | 28 checks: fixtures + a negative control on a real archived paper |
|
||||
| `run_checks.py` | the gate: 5 legs, 11 assertions, exit 0 only if all hold |
|
||||
| `CHECK.sh` | the one-command lane gate, exit code = verdict |
|
||||
|
||||
## The rules (all deterministic, no model)
|
||||
|
||||
1. A fenced block whose info string names a programming language is code.
|
||||
2. A fenced block larger than 400 chars is code (a paper's quoted equation or
|
||||
snippet is far smaller).
|
||||
3. A shell invocation in the prose (`$ pip install …`) is code.
|
||||
4. An assignment that calls into a runtime (`x = torch.nn.Transformer()`) is
|
||||
code. A bare maths assignment (`x = 1`) is NOT — that boundary is asserted.
|
||||
5. An unclosed fence is a parse fault.
|
||||
|
||||
`find_injected_code` reports every code fence with its line range, so a block is
|
||||
visible even when the document-level verdict is unaffected.
|
||||
|
||||
## Evidence
|
||||
|
||||
python3 run_checks.py # 11 passed, 0 failed, exit 0
|
||||
bash CHECK.sh # VERIFIED, exit 0
|
||||
|
||||
The negative control in `CHECK.sh` copies the real run, injects a fenced Python
|
||||
block into `paper.md`, recomputes the manifest digest, and requires the gate to
|
||||
exit 1. It does.
|
||||
|
||||
## Verdict
|
||||
|
||||
`VERDICT: the archive's published markdown is graded as prose by a deterministic partition, and code injection into it is caught; 11/11 gate assertions hold.`

||||

||||

arxiv_fulltext.py — Archive-lane tool: resolve -> download -> parse -> normalize -> manifest.
|
||||
|
||||
Pipeline
|
||||
--------
|
||||
1. arXiv Atom API metadata query (pinned version IDs only, no version drift)
|
||||
2. Full text from arXiv HTML v2 (ar5iv / arxiv.org/html/<idvN>) -> clean markdown
|
||||
Fallback: PDF -> pdftotext -layout (arXiv's own LaTeX render)
|
||||
3. Normalize: section splits, header/line-number strip, reference-list extraction,
|
||||
figure/table captions, math/code fences
|
||||
4. Manifest with SHA-256 digests of raw + derived artifacts, byte/line/section counts,
|
||||
and a tokenizer-free approximate token count (chars/4)
|
||||
|
||||
No third-party deps. Stdlib only (urllib, xml.etree, hashlib, re, json).

"""Sphinx lane work 2026-10-25: a deterministic PROSE partition for the
|

archive-lane arXiv fulltext pipeline.
|
||||
|
||||
Why this exists
|
||||
---------------
|
||||
arxiv_fulltext.py converts arXiv HTML/PDF into markdown and publishes a
|
||||
manifest. Its existing tests (test_arxiv_fulltext.py, 29 checks;
|
||||
test_units.py, 28 checks) assert on STRUCTURE -- headings, references,
|
||||
captions, digests. None of them asserts the one property the archive exists to
|
||||
preserve: that the published `paper.md` is the paper's PROSE, and not a
|
||||
document with code injected into it. A tampered paper.md whose digests were
|
||||
recomputed would pass every existing check.
|
||||
|
||||
prose.py is that missing assertion, stated as deterministic predicates on real
|
||||
text:
|
||||
* a fenced block whose info string names a programming language, or whose
|
||||
body exceeds a prose-quotation size, is code;
|
||||
* a shell invocation sitting in the prose is code;
|
||||
* an assignment/definition shape sitting in the prose is code;
|
||||
* an unclosed fence is a parse fault.
|
||||
It carries a negative control (code injected into a real archived paper) so the
|
||||
assertion cannot pass vacuously, and `find_injected_code` locates every code
|
||||
fence with its line range so a block is visible even when the document-level
|
||||
verdict is unaffected.
|
||||
|
||||
MEASURED (printed by the CHECK run below):
|
||||
* every fixture verdict in test_prose.py
|
||||
* the verdict on the real archived bytes under runs/
|
||||
* that three distinct mutations are caught
|
||||
CLAIMED: nothing in this file is claimed; every statement is backed by a check
|
||||
whose exit status the gate reads.

"abstract": "The dominant sequence transduction models are based on complex recurrent or convolutional neural networks in an encoder-decoder configuration. The best performing models also connect the encoder and decoder through an attention mechanism. We propose a new simple network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely. Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train. Our model achieves 28.4 BLEU on the WMT 2014 English-to-German translation task, improving over the existing best results, including ensembles by over 2 BLEU. On the WMT 2014 English-to-French translation task, our model establishes a new single-model state-of-the-art BLEU score of 41.8 after training for 3.5 days on eight GPUs, a small fraction of the training costs of the best models from the literature. We show that the Transformer generalizes well to other tasks by applying it successfully to English constituency parsing both with large and limited training data.",

test_arxiv_fulltext.py — regression test for the archive-lane arXiv pipeline.
|

|

Run: python3 test_arxiv_fulltext.py
|
||||
|
||||
This is a REAL test, not a tautology: every assertion checks a property of the
|
||||
actual parser against real fetched arXiv data (or synthetic fixtures for the
|
||||
units that need deterministic input). It exits 0 only if every check passes.
|
||||
|
||||
What it proves
|
||||
--------------
|
||||
U1 HTML conversion emits ATX headings and math fences (no tag leakage)
|
||||
U2 Section splitting recovers the paper's real hierarchy
|
||||
U3 Reference extraction returns N entries with non-empty text
|
||||
U4 Caption extraction finds figures and tables
|
||||
U5 Metadata is version-pinned and carries the abstract
|
||||
U6 Manifest digests actually match the bytes on disk (tamper check)
|
||||
U7 PDF fallback path parses text and its manifest says source=pdf
|
||||
U8 Negative control: a garbage input yields 0 refs, not a crash
