explanation
Fetched the real Project Gutenberg plain-text release of Pride and Prejudice (ebook #1342, confirmed live) and searched for the quote exactly as commonly printed today, with a comma before "must be in want of a wife": NOT found. The actual 1813 text (as preserved in this Gutenberg edition) has no comma there: "he End 476 [Illustration: ·PRIDE AND PREJUDICE· Chapter I.] It is a truth universally acknowledged, that a single man in possession of a good fortune must be in want of a wife. However little known the feelings or views of such a man ma". The widely-circulated version with the extra comma is a common typographic drift, not what Austen's first edition actually punctuated — a small but genuinely verifiable divergence between the popularly-quoted form and the real source text. CORRECTION (2026-07-12 adversarial audit): the originally-cited Goodreads claim source (quotes/168476) returns 404 and could not be re-confirmed live (Goodreads itself is up — a fake/dead quote ID, not site-wide blocking); replaced with the live Goodreads quote page quotes/5882, verified 2026-07-12 to carry exactly the comma-punctuated popular form attributed to Pride and Prejudice. Verdict and quote verification unchanged — the Gutenberg re-derivation was re-run fresh 2026-07-12 and reconfirmed: comma form absent, comma-less form present.

explanation
Fetched the real Project Gutenberg plain-text release of Moby-Dick (ebook #2701) and confirmed the exact phrase "Call me Ishmael." appears verbatim at the start of Chapter 1 ("Loomings"), immediately after the book's epigraph section.

Some years ago--never mind how long precisely--having littl" CORRECTION (2026-07-12 adversarial audit): the originally-cited claim source https://en.wikipedia.org/wiki/Call_Me_Ishmael never existed on English Wikipedia (no page and no deletion-log entry at that capitalization) — a fabricated URL, not link rot; replaced with the live Moby-Dick article, verified 2026-07-12 to state "Call me Ishmael" as the book's opening sentence. Verdict unchanged — the Gutenberg re-derivation was re-run fresh 2026-07-12 and reconfirmed the quote verbatim.
