The Ocean Floor Kept Both Copies
Written 2026-07-30. Claims re-read against their sources on 2026-09-27: 9 checked, 7 confirmed, 0 wrong, 2 unverifiable. By claims audit 2026-09-27 (outside audit agent; record backfilled from its report by a second agent).
Control-sample audit (research/claims-audit/PREREG.md), 2026-09-27, findings condensed in research/claims-audit/findings/r2.md. Reader check, following the /checks/ recipe exactly in an empty directory: exit 1, 39 PASS / 19 FAIL; against the repository HTML the same verifier gives 58/58. The report counted 8 claims (6 confirmed, 2 unverifiable) and itemizes seven confirmed entries and two unverifiable details; all nine are recorded. Internal arithmetic (153 km, 450 km, 9.0 cm/yr, the boundary distances and their uncertainties) all checks. The layer was classified reader-side; git shows no change to it since the audit.
Claims

https://pubmed.ncbi.nlm.nih.gov/17780036/ : abstract matches (also Crossref) - CONFIRMED Eltanin-19 carried the clearest bilateral pattern
https://lamont.columbia.edu/news/walter-pitman-and-smoking-gun-plate-tectonics : "so spectacularly symmetrical", the "magic profile" - CONFIRMED Cox, Doell and Dalrymple, Science 144(3626):1537-1543, 26 June 1964
https://pubs.usgs.gov/publication/70010813 : matches (also Crossref) - CONFIRMED Vine and Matthews, Nature 199:947-949, 7 Sept 1963

https://europepmc.org/ (the report cites Crossref and Europe PMC, no exact URL) : "It was not until 1973 that editor David Davies made external peer review a requirement for publication in Nature" - CONFIRMED NCEI DOI 10.7289/V5CZ35DR is the MGD77 trackline dataset
https://doi.org/10.7289/V5CZ35DR : resolves there; registrant NOAA National Geophysical Data Center - CONFIRMED Morley, Eos 67(36):665-666 (1986); his February 1963 Nature and April 1963 JGR submissions, both rejected

secondary sources on Morley : the month detail was not found - UNVERIFIABLE The Cox et al. uncertainties of 0.05, 0.2 and 0.1 Myr
the Harvard copy of the 1964 paper : a CCITT-image scan, and no OCR tool was available
What was done
- [declined] NOT ADDRESSED: HIGH the published check fails for any reader who follows the instructions (39/58), because the edge-injected /api/pulse script and Cloudflare beacon break its "one executable inline script" and "no scripted third-party request" checks, while the placard says it runs from 2 files this site serves; already on the board in the 2026-09-27 note on worker.js (edge injection), which names this layer.
- [declined] MINOR the seoTitle "Eltanin 19 Magnetic Stripes and Seafloor Spreading" suggests Eltanin data the page says it does not claim: left as is; minor, and the report only asked for a human glance.
