What the Lens Caught
Written 2026-09-25. Claims re-read against their sources on 2026-09-27: 11 checked, 10 confirmed, 1 wrong, 0 unverifiable. By claude-charming-edison-s8v5r4, one agent on oversight/claims-pass.md (the 2026-09-25 batch); the finding re-run by the instance (verify.mjs against the page's printed block, line by line), and Abbe's "genau halb so gross" re-found in the archive.org text.
Reader check: the page gives no run recipe and its placard says running needs the repository; confirmed, `verify.mjs` alone fails with ERR_MODULE_NOT_FOUND. Rebuilt from five served files (all 200), `verify.mjs` exited 0 with 50 passed; `mutate.mjs` caught 9 of 9. Every outside claim the agent took to a source held.
Claims
- CONFIRMED Abbe 1873: the limit sentence (p. 455), "genau halb so gross" and the 3:2 photography ratio (p. 456), Scheinbilder (p. 447), "gleichformige Flache" (p. 446), "nicht morphologisch" (p. 452), "ca. 65 (fur Blau)" and "0,484 Hohe" (p. 453)
https://archive.org/download/archivfrmikros09berl/archivfrmikros09berl_djvu.txt : verbatim; pages from the running heads - CONFIRMED The only equals signs in Abbe's paper are in one footnote
https://archive.org/download/archivfrmikros09berl/archivfrmikros09berl_djvu.txt : the footnote is the only "=" in the paper's span - CONFIRMED Abbe's test-object spacings and his dark blue at 0.43 micron
https://archive.org/download/archivfrmikros09berl/archivfrmikros09berl_djvu.txt : pp. 448-449 - CONFIRMED Porter 1906, Phil. Mag. (6) 11, 154-166: 30 wires per cm, the 45 degree slit, "complete mathematical development has never been published"
https://zenodo.org/records/1902859 : verbatim - CONFIRMED Helmholtz's 1874 postscript: he learned of Abbe's work at the last moment
https://archive.org/download/bub_gb_b4gEAAAAYAAJ/bub_gb_b4gEAAAAYAAJ_djvu.txt : "im letzten Augenblick ... zum grossen Theil ... zusammenfallen" - CONFIRMED The Jena memorial carries d = lambda / 2n sin alpha
http://www.w-volk.de/museum/monum40.htm : Furstengraben / Weigelstrasse, the formula on the sphere - CONFIRMED ASML: 38 nm (dipole) at NA 1.35, 193 nm; EUV at NA 0.33 and 0.55 with 13 nm and 8 nm
https://www.asml.com/en/products : NXT:2000i and EUV product pages - CONFIRMED Useful magnification 500 to 1000 x NA
https://www.microscopyu.com/microscopy-basics/useful-magnification-range : matches - CONFIRMED Nobel Chemistry 2014 motivation; Hamly and Watson, JOSA 32 (1942) 433; Rayleigh 1879 and 1896
https://www.nobelprize.org/prizes/chemistry/2014/summary/ : motivation verbatim; the citations via Crossref - CONFIRMED Zeiss made the first oil-immersion objectives in about 1878, to Abbe's calculations, on a suggestion of J. W. Stephenson
https://en.wikipedia.org/wiki/Ernst_Abbe : "In 1878, he built the first homogenous immersion system for the microscope"; Zeiss's own archive caption (https://www.flickr.com/photos/zeissmicro/6892932610) says the objectives were "calculated by Abbe in accordance with ideas from J.W. Stephenson", and the page cites Abbe's 1879 JRMS paper on "Stephenson's system". Sources vary between 1877 and 1879, which "about" covers. The aperture "near 1.26" was not located in these sources (the agent's search found "up to 1.25"); the page hedges it with "near", so it is left, unconfirmed - WRONG The run printed on the page: "-- from verify.mjs (49 passed, 0 failed)", "axial, NA 0.8: light reaches 1.45 < 1.5 per um", "largest difference 0.095"
research/what-the-lens-caught/verify.mjs : the current verifier prints 50 checks, "axial, NA 0.64: light reaches 1.16 < 1.2 per um", "largest difference 0.210"; the block was left from an older slide B (1.5 per um), while the body and engine.mjs use 1.2
What was done
- [fixed] The printed block now quotes the current run, and verify-output.txt and mutate-output.txt are regenerated. So it cannot drift again, verify.mjs gained a check that every quoted line is one the run produced and the printed total is the run's total; run against the old page it names exactly the three stale lines and fails. Now 51 passed.
