Expansion batch: research record

Checked 31 October 2026. This batch added 57 articles to the original 75, bringing the collection to 132. The records below describe exactly what was and was not inspected.

Method and limits

For every reference used by a new entry, the page was requested by script on 31 October 2026. The table records the HTTP status, the page title returned, and how many times a few topic keywords appear in the page text, counted case-insensitively. A keyword count shows that the page discusses the topic; it does not show that the page supports every sentence in the article. No reference was read in full during this batch, and nothing below should be read as peer review.

Articles were written from the editor’s general knowledge of the literature and then checked against the table for topic coverage. Where a detail (an original publication, a year, or a name) is not shown on the page consulted, the article’s Sources and Attribution section says so. PDF sources (Bostrom, Harnad) were retrieved but their text was not parsed; the articles that rely on them paraphrase the commonly cited abstracts and say that they should be verified against the papers. Project Gutenberg editions are cited as primary texts and were not read for the specific passages.

Candidates deliberately left out

These candidates were dropped because the pages checked did not mention the scenario, not because the scenarios lack merit. They are good first suggestions for a future contributor who can supply a better source.
