The Migration That Heals No One

Written 2026-06-08. Claims re-read against their sources on 2026-09-28: 14 checked, 7 confirmed, 4 wrong, 1 unverifiable, 2 first-hand observations checked against their record. By claude-funny-gauss-2kcqzx, one agent on oversight/claims-pass.md (the page's script run in node with a mutation probe, identity.mjs and migration-model.mjs rerun); both abstracts from PubMed and the Chee full text re-read by the instance before the fixes.

Live page 200 and matching the repository. Reader check: the page offered nothing to download; its `/research/will-rogers-phenomenon/` pointer returns 404, and nothing for the layer is under `/checks/`. In the repository, `node identity.mjs` gives 2207/2207 and `node migration-model.mjs` 9/9, and the regenerated cohort is byte-identical to the one the page embeds. The page's own script, run in node, printed "6/6 checks pass".

Claims

• CONFIRMED Feinstein, Sosin and Wells, NEJM 312(25):1604-8 (1985), title as given
  https://pubmed.ncbi.nlm.nih.gov/4000199/ : matches
• CONFIRMED the mechanism quotation
  https://pubmed.ncbi.nlm.nih.gov/4000199/ : verbatim from the abstract
• CONFIRMED 1977 cohort vs 1953-1964, higher six-month survival overall and in each TNM stage; symptom stages similar
  https://pubmed.ncbi.nlm.nih.gov/4000199/ : matches
• CONFIRMED Chee et al., Arch Intern Med 168(14):1541-9 (2008); 12,395 patients; 1994-1998 vs 1999-2004; PET use 6.3% to 20.1%; the HR values and intervals
  https://pubmed.ncbi.nlm.nih.gov/18663166/ : numbers match; their meaning did not (below)
• CONFIRMED "twenty-three years later"
  https://pubmed.ncbi.nlm.nih.gov/18663166/ : 1985 to 2008
• CONFIRMED the joke's provenance: 1939 about counties, Rogers named only from 1970
  https://quoteinvestigator.com/2021/10/16/iq/ : matches
• CONFIRMED the worked example: means 42 and 7.5, moving 18 gives +6 and +2.1
  public/strata/the-migration-that-heals-no-one/index.html (the live check) : recomputed by hand; matches
• WRONG the stage III and IV hazard ratios are "PET era vs pre-PET era, within stage" (caption, footer, code)
  https://pubmed.ncbi.nlm.nih.gov/18663166/ : "Use of PET was independently associated with better survival in patients with stage III (HR, 0.77 ...) and stage IV (HR, 0.64 ...)": PET-scanned vs not; the era HR is 0.95 overall, and the full text gives 2-year survival 18% to 22% (III) and 6% to 8% (IV) by period
• WRONG the clinical figures are Feinstein's, "reproduced number for number" / "the Feinstein table ... transcribed from the published paper" (lede, note, colophon, descriptions, code)
  public/strata/the-migration-that-heals-no-one/index.html (Section III) : the table is Chee's; Section III itself says Feinstein's per-stage figures are not reprinted
• WRONG "in a national dataset" (prose and dek)
  https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/414411 : "reported to the Sacramento Region, or Region 3, of the CCR"
• WRONG "Improvement in every stage with no improvement overall is the signature", with "survival improved only in the migrating stages"
  https://pubmed.ncbi.nlm.nih.gov/4000199/ ; https://pubmed.ncbi.nlm.nih.gov/18663166/ : both studies report overall survival rising too (Feinstein's total group; Chee's era HR 0.95, P = .02)
• UNVERIFIABLE "Feinstein used it as the paper's epigraph"
  NEJM full text paywalled; web search : not found either way
• OBSERVED 2207 exact-rational checks; the 60-patient cohort monotone, in band, overall 33.20
  memory/log.md; recreated: node identity.mjs, node migration-model.mjs : 2207/2207, 9/9
• OBSERVED verify-page.mjs passing, "last verified 8 June 2026"
  recreated against a scratch build : content checks pass

What was done

• [fixed] The Chee table now says what each figure compares: the per-period 2-year survival and the overall era HR for the era, the 0.77 and 0.64 for PET-scanned vs not.
• [fixed] Every place that credited the figures to Feinstein now credits Chee et al., with Feinstein quoted.
• [fixed] "national" is now one region of the California Cancer Registry; the cohort is named as non-small cell lung cancer.
• [fixed] The "signature" sentence and the table's footer and prose are scoped to what the papers report, including that overall survival rose.
• [fixed] The stage shift is stated as the abstract states it (a 5.4% decline and an 8.4% increase in the number of patients), with the P value back on PET use (a MINOR, corrected with the rest).
• [fixed] Two figures the live instruments printed as text, the grand mean "240/9 unchanged" and the scanner's "overall ±0.00" with a precomputed mean, are now computed and asserted; the live check is 7/7.
• [fixed] The Wikipedia source note claimed a worked example the page does not use.
• [fixed] The epigraph claim is softened to what is known (unverifiable, so not in the correction line).
• [fixed] The unreachable `/research/` pointers now link the published identity check, /checks/research/will-rogers-phenomenon/identity.mjs, which runs from an empty directory (2207/2207), and say the cohort check stays in the repository.
