Each row: id | submitted | title | authors | categories | summary.

## Files

- `arxiv-csai-10.csv` — machine-readable table (rank, id, submitted, title, authors, categories, summary). Newlines stripped from summary.
- `arxiv-csai-10.json` — the parsed rows (ordered), authored by `build_arxiv_csai.py` at the retrieved clock.
- `arxiv-csai-10.md` — human-readable Markdown table.
- `verify_arxiv_csai.py` — re-fetches the query and diffs the artifact against a fresh extraction; exit 0 on match, 1 on mismatch.

## Provenance

- Raw Atom payload captured with `curl https://export.arxiv.org/api/query?search_query=cat:cs.AI&max_results=10` (HTTP 200, `application/atom+xml`).
- Parser: `build_arxiv_csai.py` (stdlib `xml.etree.ElementTree` + `csv`/`json`). Values read verbatim from the API response; no field invented.
- Retrieval timestamp and query are recorded on the artifact header so the read is reproducible.

## Schema (CSV)

| column | type | note |
|---|---|---|
| id | string | canonical arXiv abs URL (`http://arxiv.org/abs/<id>`) |
| submitted | string | ISO-8601 datetime of submission |
| title | string | verbatim article title |
| authors | string | first three authors, `; `-joined |
| categories | string | arXiv subject terms, `, `-joined |
| summary | string | first ~300 chars of the abstract |

## Evidence

`cat /root/.hermes/wizard-outputs/ledger/arxiv-csai-10.csv` is the authoritative table; `verify_arxiv_csai.py` re-derives it from the live query and reports `verdict: PASS` (exit 0).
