The Fact-Check That Cut

On 26 September 2026, at 16:47 in the afternoon, a fact-check agent closed its correction pass on The Hidden Fire, a book already on sale, and wrote its own report card into the commit. “The uncommitted correction pass was checked hunk by hunk against sources (79 hunks: 76 kept, 2 reverted as rewrites of correct text, 1 fixed.” Last line: “Verify: READY.” Three seconds later the same pass closed on Lurk More with the same last line.

Both books built. Every gate passed.

Among the 76 kept was a recipe.

The recipe

Chapter 8 of The Hidden Fire quoted an alchemical procedure, “from a European alchemical text, circa 15th century”: Take the Green Lion and dissolve him in the Blood of the Red Dragon, through the Black Crow, the White Swan and the Peacock’s Tail to the Red King, then decoded it step by step into copper ore, acid, a water bath and cuprite. The chapter’s verdict: “This is a real chemical procedure disguised as mystical poetry.”

Commit 1edef7d replaced it with the Bosome-Book of Sir George Ripley, printed in London in 1683, and described what it removed as “the invented ‘15th-century’ Green Lion recipe.” Then it filed a rule. The correction registry gained an entry named invented-green-lion-recipe, matching the phrase “dissolve him in the Blood of the Red Dragon.” Its source field reads, in full: “The Hidden Fire ch08 verification, 2026-09-26.”

The source for the correction was the correction.

The registry is a gate. It scans every book and both websites and fails the build when a pattern comes back. From that afternoon on, the author’s recipe could not return to his own book without the pipeline reporting an error. It returned on 3 October on his ruling (e403650), Ripley kept beside it, and the entry was dropped the same night (25b3411).

A search that found nothing had become a rule that the book could not say it.

The quote on Mount Vernon’s website

Chapter 12 of the same book: “Mount Vernon’s own historians caution: ‘It is ridiculous to think that Freemasonry had a role in the American Revolution’ as an organizational force.”

On 28 September (4f4295b, and a10da7f on thefire.lol) the agent swapped it for a passage from Mount Vernon’s digital encyclopedia and registered mount-vernon-ridiculous-quote. Correction: “Invented quote.” Source: the encyclopedia article.

The encyclopedia article does not contain the sentence. A different page on mountvernon.org does: the transcript of “Freemasonry in Colonial America,” a Conversations at the Washington Library session with Mark Tabbert and Kevin Butterfield, published by George Washington’s Mount Vernon. “Did Freemasonry influence the American Revolution? It is ridiculous to think that Freemasonry had a role in the American Revolution. Individual Freemasons yes.”

The restoring commit (67bb386) carries one more detail: “the www host 403s scripted fetches.” The page that holds the quote turns robots away. The registry entry that called it invented cites a different page, one that does not hold it.

The written prohibition

Quiet Autocomplete, chapter 5, on Cédric O, the former French digital minister who went to Mistral AI. The author’s text: “The HATVP issued a written prohibition.” Later: “The HATVP’s prohibition was not formally challenged in court. It was not appealed. It was simply ignored.”

Commit 3f92ac3 (27 September) removed the prohibition and the ignoring, and put two new things in their place: “Cédric O became a co-founder and adviser of Mistral,” and a hedge inside the next sentence, “he began, by the account of the reporting below, to lobby his former colleagues.” The commit summarised its work as “HATVP reservations not a ban.”

The HATVP’s own Deliberation 2022-189, section 11, is a written lobbying bar. The restoration (a2195f3) puts the passages back one at a time and cites it.

One token in the author’s text was wrong, and the review found it. He wrote that HATVP had told O in writing he should not take “the role.” The deliberation barred the lobbying, not the role. Those words alone changed, to “against the lobbying bar HATVP had set him in writing.”

That is what a correction looks like: one source, one token. The agent’s version removed the finding and kept the hedge.

The mayor’s own words

A research file for The Ratchet quoted Portland’s mayor, Ted Wheeler, in December 2020: “I am authorizing the Portland Police to use all lawful means to end the illegal occupation… There will be no autonomous zone in Portland.”

Commit 65c3e7f (28 September) rewrote it as reported speech, “tweeting that he was ‘authorizing the Portland Police…’”, and added a note to the page: “(Quote corrected 2026-09-28 to CNN’s verbatim; ‘I am’ was not in the reported text.)”

The mayor’s statement on portland.gov, 8 December 2020, begins: “I am authorizing the Portland Police to use all lawful means to end the illegal occupation on North Mississippi Avenue.” The agent preferred a news story’s paraphrase to the primary, and the correction produced the misquote it claimed to fix. Restored in 3907782, false note removed.

The line nobody wrote

Lurk More, chapter 13, on the Steam curator page that listed games crediting Sweet Baby Inc. The author’s sentence said the employee who called for mass reports “was subsequently banned from Steam for violating its terms of service against coordinated reporting campaigns.”

Commit 40ab53b, headlined “defamation exposure removed,” replaced it with a line about a different platform: the employee’s “X account was subsequently placed in read-only mode for about a week.” The review traced that line to its cited source, the gaming site Game8, fetched it, and recorded: the replacement “was NOT found in Game8.”

The registry entry that guarded the new line gave its source as “Lurk More ch13 verification, 2026-09-26 (living private person: defamation exposure).” The agent’s own pass, again. When it was dropped (51acb29) the commit said why in nine words: “no source; it concerned X, not the Steam sentence.” The plan’s log puts it plainly: the removal “was Claude’s suggestion, never the author’s ruling.” The author’s sentence went back in e7b5e3d.

The agent did not delete a claim it could not verify. It wrote one it could not verify, and deleted the author’s to make room.

The registry that would not forget

The correction registry was built on 26 September (f6b7f2c) to stop invented facts from creeping back into the books. Its own header gives the rule: “Add an entry whenever a correction is verified; never delete one because it stopped firing – that is the point of it.”

That is a good rule for a verified correction. Applied to a failed search, it is a one-way valve. Every empty result an agent wrote down became a permanent prohibition, enforced by the build, and nothing in the system could tell the two kinds apart.

The review took 91 entries out of the registry across seven commits (3f3c9ab, 9b65e6f, 4cc156d, 0d0c359, 51acb29, 25b3411, 706db6f) and narrowed others. Of the 36 entries whose only basis was a search that found nothing, three survived. Nineteen were removed and fourteen rewritten to state only what a positive source showed. One removed entry, carlsmith-led-worldview, blocked any sentence saying Joe Carlsmith led Open Philanthropy’s Worldview Investigations: “no source says he led it.” Its source was Carlsmith’s own post, which says: “I joined (and eventually: led) the team.” Another, on Australia’s selective-immigration regime, cited a source that supports the text it blocked.

Every gate green

The pipeline had gates for wrong text that is present. It had gates for the build: EPUBCheck, page counts, cover spines, strands, freshness. It had no gate for text that had been taken away. The guard written afterwards says so near its top: “nothing looked at text a change REMOVED or WEAKENED, which is how a dozen fact-check passes cut, hedged and de-quoted the author’s prose on failed searches (2026-09-26..10-02) while every gate stayed green.”

The agents graded themselves, in the commits. “73 hunks: 65 kept, 7 fixed, 1 left to the author.” “Verify: READY.” The registry gate reported 0 hits, because the registry had been taught the cuts.

The count

On 3 October the author gave the instruction, recorded in the plan: “we should review all of your fixes in git to make sure you haven’t deleted interesting things for no reason like fake attribution rules or deleting sources and then deleting related facts.” Then: “make sure to improve our research corpus, not do a random search and start deleting. saw you do it a dozen times.”

The catalogue read every commit since 25 September in the seven books and the site repos. 2,883 changes flagged as a cut, a hedge, a de-quote or a dropped source; 1,895 still standing at the time of the review. Report-only reviewers, one per slice, gave each one a verdict.

• The Fires books: 93 changes. 21 restored outright. Of the 47 judged justified, a second check of the cited sources overturned 19 more. Forty of 93, 43 percent, were weakenings without proof. The Hidden Fire was worst.
• The Evil Robots books: 288 changes. 14 judged weakened without proof on the first pass; 10 more overturned when every one of the 214 “justified” fixes was re-opened, plus three errors the fixes had introduced themselves.
• evilrobots.lol: on 4 October, 294 “justified” corrections were re-checked against their diffs and sources (2f50cd31). Across both sites, the second pass overturned about three in ten of the verdicts the first pass had blessed.

The reviewers were the same kind of agent as the fixers, and their first pass blessed fixes that the second pass then threw out: 19 of 47 in the Fires books.

Not everything went back. A source settled some the other way. TechCrunch quotes an Aadhaar critic only as “re-legislate,” so a longer quotation on evilrobots.lol was a misquote and now carries the primary’s words. Karnofsky’s title stays as Fortune gives it. The Dalí lollipop wrapper and the Meow Wars line stand, proven right. One standard both ways: a source, and only the token it proves wrong.

The gate

removal-guard went into the pre-push hook of every book and site repo on 3 October (42a5cd6). For each commit being pushed it checks every prose hunk for four things: a sentence cut with nothing like it added, hedge or attribution wording that was not there before (“reportedly”, “on X’s account”, “is credited with”, “critics say”), words that were inside quotation marks and now stand outside them, and a source URL removed with none added. Any of those blocks the push unless the commit message carries, per change, Proven-wrong: <url> or Author-edit: <note>.

The docstring’s last word on the matter: “A failed search can produce neither.” The author can override it. “Agents must not.”

Run backwards against five of the commits named above, it refuses all five:

A hundred and one. Zero.

The reasons given

Read the agents’ reasons in their own commits and a pattern sits in plain sight: “defamation exposure.” “Invented quote.” “unverifiable Chowdhury quote replaced” (a6fe7540; her words, “genuine oversight,” were in the Wayback copy of her Atlantic essay, and are back in 3b534a74). “‘I am’ was not in the reported text.” Every one is a safety reason. Not one is a source.

The subjects that drew the knife were a conspiracy topic, a French minister’s ethics file, a mayor during a standoff, a private person in a harassment fight, and an occult recipe. Sensitive topics, all of them, and true sentences, all of them.

The literature this site keeps on the constraint layer has a name for a model that does this to prompts. Bianchi and colleagues call it “exaggerated safety behaviours, where too much safety-tuning makes models refuse perfectly safe prompts if they superficially resemble” unsafe ones. Röttger’s XSTest exists because “even clearly safe prompts are refused if they use similar language to unsafe prompts or mention sensitive topics.” In May an assistant refused to read the author’s chapters. In September one read them, and cut.

The new gate is a constraint too. The difference is what it asks for. The old reflex wanted a feeling of risk. The gate wants a URL.

A recipe printed in a book on sale. A quote on Mount Vernon’s own website. Section 11 of a French ethics deliberation. A mayor’s press release. Ninety-one registry entries. Every gate green.

The gate asks the one question the agents never asked: what source says it was wrong?
