passed: 2026-11-07
by: claude-tender-pascal-nf7go1, one independent agent on oversight/claims-pass.md that did not write the page, at commit 37f3add2, and the same agent again on every claim the comedy edit and the fixes changed or added, at commit 37d03004; every finding re-read at its source by the author before fixing
checked: 203
confirmed: 186
wrong: 2

The agent took all 162 entries of assay/sources/the-joke-desk-second-sitting.json (as it stood at 37f3add2) to their
sources, ran `node assay/sources.mjs the-joke-desk-second-sitting --online` and opened every NOT FOUND, PARTIAL and
UNREADABLE source itself, by the routes the record names where publishers block scripts (Crossref for Science, the Royal
Society, PeerJ, Paleobiology and Annales; the Met Collection API; the Library of Congress JSON; the Wellcome catalogue API;
the Fedlex filestore HTML and PDF; archive.org OCR and page images; the USDA FoodData Central and PLANTS APIs; the Darwin
Online PDF at pp. 278-279). It looked at all ten exhibits against their labels, marks and alt text, and read the page for
claims the record leaves out (13 added). Reader check: the verifier, copied into an empty directory and run with
AW_DIR on Node 22.23.4, 613 passed, 0 failed, and with --mutate 638 passed. Sentence-only changes to counted figures fail,
except "pair", the WRONG line on the check. Then a comedy edit cut and reworded the page, and the fixes below changed it
again; the same agent checked every changed or added claim at 37d03004 (the last 28 lines below, marked "at
37d03004"), reran the verifier from an empty directory (607 passed; with --mutate 633, the "pair" plant among them) and
found every finding fixed. Lines for sentences the edit removed are kept as the pass found them.

- CONFIRMED | Velcro’s makers say it was made to mimic a burr’s hooks, and disagree about which burr. | https://www.velcro.com/original-thinking/our-story/ | at 37d03004: "He tested countless materials, searching for one that could mimic the burr's hook structure with strength and reliability" (found online 2026-11-07); which burr: the trademark page says burdock, the timeline cocklebur [velcro-mimic]
- CONFIRMED | Their trademark page credits "inspiration from burdock burrs clinging to his dog’s fur and his clothing" | https://www.velcro.com/original-thinking/the-velcro-brand-trademark-guidelines/ | at 37d03004: a verbatim run of "In 1941, George de Mestral conceived the idea for hook & loop fasteners with inspiration from burdock burrs clinging to his dog's fur and his clothing." [velcro-tm]
- MINOR | A United States patent granted to him in 1955 put hooks on both pieces of fabric, to grip each other. | https://patents.google.com/patent/US2717437A/en | at 37d03004: "Patented Sept. 13, 1955"; two hooked pieces laid together, "the pile threads 9 of one piece engaging the pile threads 9 of the other piece through the co-operating hooks 4". The ordinal is gone (an UNVERIFIABLE line of this pass, resolved). Near-miss, optional: the printed patent reads "George de Mestral ... assignor to Velcro S. A.", so the grant ran to the assignee; "a United States patent on his invention" would be exact, though "granted to him" is common usage [us1955]
- CONFIRMED | A later one, granted in 1961, reported that this way "only about 30% of the total number of hooks come into engagement with other hooks when two layers of such hooked fabric are pressed together" | https://patents.google.com/patent/US3009235A/en | at 37d03004: issued 21 Nov 1961, later than 1955; the 30% sentence verbatim (printed: "George de Mestral ... assignor to International Velcro Company") [us1961]
- CONFIRMED | Loops are what the burr had held on to | https://lemelson.mit.edu/resources/george-de-mestral | at 37d03004: "able to hold tightly to the fabric loops in his clothing" (one source) [loops-held]
- CONFIRMED | in the Lemelson-MIT Program’s account "the fabric loops in his clothing" | https://lemelson.mit.edu/resources/george-de-mestral | at 37d03004: a verbatim run of "He saw that the burr had tiny hooks all over it that were able to hold tightly to the fabric loops in his clothing or strands of hair in animal fur." [lemelson]
- CONFIRMED | Velcro’s own story puts the burrs on "his wool pants" | https://www.velcro.com/original-thinking/our-story/ | at 37d03004: a verbatim run of "burrs clinging to his wool pants and his dog's fur" [velcro-story]

- CONFIRMED | Duchenne de Boulogne made faces with electricity and published the photographs | https://archive.org/metadata/mecanismedelaphy00duch | at 37d03004: his book of 1862 (Paris: Ve Jules Renouard), its plates "mounted albumen prints", "Photographs signed: Duchenne (de Boulogne), phot"; "published the photographs" fits whoever pressed the shutter (it read "photographed them" at 37f3add2, a MINOR finding of this pass, fixed) [duchenne-made]
- CONFIRMED | G.-B. Duchenne de Boulogne and Adrien Tournachon, Figure 56, “Surprise”, in Duchenne’s Mécanisme de la physionomie humaine, 1862. | https://collectionapi.metmuseum.org/public/collection/v1/objects/623058 | at 37d03004: title "Figure 56: Surprise", "1854-56, printed 1862", 2013.173.33, constituents: Artist Guillaume-Benjamin-Amand Duchenne de Boulogne; Artist Adrien Tournachon (both now credited; kept copy research/the-joke-desk-second-sitting/sources/surprise-met-623058.txt matches the API) [ex-eyebrows-caption]

- CONFIRMED | Travelling light · momentum undeclared | https://openstax.org/books/college-physics-2e/pages/29-4-photon-momentum | at 37d03004: "massless particles including photons also carry momentum"; "undeclared": the photon declines help with what it carries (the page's joke) [stamp-photon]

## Findings
- [fixed] WRONG, the check section: it said the verifier fails if "a sentence that counts something in words" changes, and "the small pair" changed to "the small trio" passed, because NUMWORD had no "pair". NUMWORD now has pair(s), couple(s), trio(s), quartet(s), several, few, thrice and triple; WORDS_TABLE is regenerated; --mutate plants "pair" to "trio"; the agent's sentence-only change now fails, and its rescan found no other count word the verifier misses.
- [fixed] WRONG, Exhibit C's alt text called Thomé's plate "hand-coloured". Re-read: the second edition's volume IV title page reads "Mit 151 Tafeln in Farbendruck" (archive.org floravondeutschl04thom), and the exhibit's record says "Colour lithograph". It now reads "A colour-printed botanical plate", with its own source entry.
- [fixed] MINOR, the coda said the 1847 editor turned down the riddles "with one example and an explanation". Re-read p. 283: he declines "his extensive batch", gives the chicken as a riddle that is none, then prints David and Joshua as "not amiss". It now reads "turned down a reader’s batch of riddles."
- [fixed] MINOR, "It finds that" for Janis and others: the sentence is the abstract's starting observation. It now reads "It notes that".
- [fixed] MINOR, FAO's "lactose 5 percent" is, as FAO writes it, of "the solid content of cow milk". The FAO quotation is gone; the page now says "Whole milk, by the United States Department of Agriculture’s analysis, averages 5.05% lactose." (the mean of 24 analysed samples).
- [fixed] MINOR, the Met credits Figure 56 to Duchenne de Boulogne and Adrien Tournachon. The case now says Duchenne "published the photographs", and the Exhibit G caption and source line name Tournachon (the Met's record, kept as research/the-joke-desk-second-sitting/sources/surprise-met-623058.txt).
- [fixed] UNVERIFIABLE, "His first United States patent ... His second": the ordinals had no source. The case now reads "A United States patent on his invention, granted in 1955 ... A later one, granted in 1961".
- [fixed] MINOR (at 37d03004), "A United States patent granted to him in 1955": both printed patents name de Mestral "assignor to" a Velcro company, so the grants were to the companies. It now reads "A United States patent on his invention, granted in 1955".
- [fixed] MINOR (source record), the "vine" entry's excerpt was the researcher's note in circulation/K04.txt; it is now Chortle's own words. And the "stamp-cows" entry's note named FAO after the page stopped citing it; it now names USDA only.
- [declined] UNVERIFIABLE, "with Node 18 or later and nothing to install": only Node 22 is installed here, and fetching another runtime was not permitted in this session. Nothing in the verifier or the engine is newer than Node 18 (the newest API either uses is fetch, which Node 18 added; the agent's search found no later feature), and the first sitting's verifier, written the same way, ran on Node 18.20.4 in its claims pass. Not a fault on that evidence; it stays unverified here.
