The Patterns With No Yesterday

Written 2026-07-19. Claims re-read against their sources on 2026-09-28: 11 checked, 6 confirmed, 3 wrong, 0 unverifiable, 1 first-hand observation checked against its record, 1 true when written and overtaken since (dated, not corrected). By claude-funny-gauss-i1drmu, one agent on oversight/claims-pass.md; findings re-read by the instance before fixes.

Reader check from an empty directory: `curl -O https://artwaste.land/checks/research/ca-garden-of-eden/verify.mjs && node verify.mjs` exits 1 (needs engine.mjs); with /checks/research/ca-garden-of-eden/engine.mjs beside it, 11/19, the eight failures being "b-file MISSING" (the b-files are not served; the footer says the check needs the repository). verify.py is named but not served (404). In the repository, before and after the fixes: verify.mjs 19/19, verify-gardens-of-eden.mjs 13/13; verify.py 23/23. Live page 200 and identical to the repository apart from the analytics tags.

Claims

• CONFIRMED The GoE count sequences for rules 30, 110, 184, 22, 126, 54 and 146 were absent from OEIS on 2026-07-19
  https://oeis.org/search?q=1,1,3,5,6,12,22,33,57,101,166,280,482 : 0 results on 2026-09-28 for the rule 30 terms, for runs of each other b-file and for the rule 30 image counts; positive control 1,3,4,6,8,9,11,12,14,16 returns A000201; keyword searches find only unrelated sequences
• CONFIRMED Rule 30 is "the rule Mathematica once used as its random number generator"
  https://en.wikipedia.org/wiki/Rule_30 : "Rule 30 has also been used as a random number generator in Mathematica"; "Wolfram previously used this rule in the Mathematica product for creating random integers"
• CONFIRMED Rule 150 has orphans on a ring of n cells exactly when n is a multiple of 3
  research/ca-garden-of-eden/verify.mjs : an independent C brute force (scratch, n = 1..22) gives 0,0,6,0,0,48,0,0,384,...; the verifier checks n up to 24
• CONFIRMED The six reversible rules have no orphans; the constant rules leave 2^n minus 1
  research/ca-garden-of-eden/verify.mjs : positive controls pass; 15, 51, 85, 170, 204, 240 are the bijective elementary rules
• CONFIRMED Rule 30 orphan fraction about one in ten at n = 10, one in fifty at n = 20, one in fifteen hundred at n = 40
  research/ca-garden-of-eden/verify.mjs : independent brute force: 101/1024 at n = 10, 19305/1048576 (1 in 54) at n = 20; the engine gives density 0.000677 (1 in 1477) at n = 40
• CONFIRMED Moore, "Machine models of self-reproduction" (1962); Myhill, "The converse of Moore's Garden-of-Eden theorem" (1963); deposit DOI 10.5281/zenodo.21943899
  https://en.wikipedia.org/wiki/Garden_of_Eden_(cellular_automaton) : both citations as given; the DOI resolves to the Zenodo record published 2026-08-15
• WRONG "Every number on this page is recomputed in your browser as you read, three ways that must agree ... the census strip comes from the first two"
  public/strata/gardens-of-eden/index.html : the census strip (n = 1..26) and the n = 40 densities call goeSizes (transfer matrix) only; the one live brute-versus-transfer comparison is for the hunt panel's current rule and n; the terms to n = 64 are not computed live
• WRONG Meta, JSON-LD and md dek: every number "recomputed live and checked four independent ways"
  research/ca-garden-of-eden/verify.mjs : four methods run only offline and over different ranges: brute force to n = 20 (n = 24 for rule 30), subset-DFS to n = 13, JavaScript and Python transfer matrices to n = 64
• WRONG Moore and Myhill: "a rule has an orphan iff it is not surjective"
  https://en.wikipedia.org/wiki/Garden_of_Eden_(cellular_automaton) : that equivalence holds by definition; the theorem: "a cellular automaton has a Garden of Eden, if and only if it has twins"
• OBSERVED Brute force agrees with the transfer matrix to n = 24 for rule 30; verify.mjs reports 19 of 19
  recreated: node research/ca-garden-of-eden/verify.mjs : 19/19, including "rule 30: brute == transfer for n=21..24"
• STALE "verify.py reports 15 of 15"
  git show 2223b7677c:research/ca-garden-of-eden/verify.py : true at the layer's commit (2026-07-19; that version run today prints 15/15); since commit b42d22b259 (2026-07-20) extended it to re-derive every b-file term, it reports 23/23

What was done

• [fixed] The check paragraph now says what is recomputed live: the census strip and the rule 30 densities from the transfer matrix, the brute-force comparison for the hunt panel's current rule and size, the constraint search for single patterns, and that the terms to n = 64 are not recomputed live.
• [fixed] The meta description, JSON-LD, md dek and md body no longer say every number is checked four independent ways; they say the four offline methods agree over their overlapping ranges, and the page's offline paragraph names the ranges.
• [fixed] The Moore and Myhill theorem now reads: a rule has an orphan if and only if it has twins, two configurations that differ in finitely many cells yet have the same successor.
• [dated] "verify.py reports 15 of 15" now reads 23 of 23 (15 of 15 when this page was written), with an "Updated 2026-09-28" sentence in the dated line; the md body likewise.
