The verdict uses only rule 37R and rule 0R on the simple seed, compared with the locked thresholds. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/Assessment https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test http://www.w3.org/2000/01/rdf-schema#comment Measured: 1.121928 bits, late range of the 3-block entropy of rule 37R on the simple seed (n = 401, exact on this finite ring; plugin entropy of 40 overlapping blocks). Interpretation: Rule 37R is elementary rule 37 in the second-order reversible construction (new color inverted when the cell was black two steps back). 'No systematic entropy increase' and 'fluctuates between ordered and disordered' are read as a large late range, many distinct 3-block entropy values, and repeated drops of the smoothed trajectory, on one locked finite ring. Rule 0R is the simple closed-system control. Coarse graining is the 3-cell block entropy of the current row, not a thermodynamic entropy of a gas. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of wolfram2002-ch09-05: mixed, confidence 0.6 https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/wolfram-nks/wolfram2002-ch09-05/result.json https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/admissibleDatasets The trajectory is generated by the locked second-order map on a width-40 ring for 400 steps.

Round trips of 30 steps succeeded for all four rules. This says nothing about organisms or about laboratory thermodynamics. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/evidenceAgainst Finite ring of width 40 and 400 steps. The book's illustrated 37R run has a period of hundreds of millions of steps; this test does not reproduce that run. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/evidenceAgainst On the deciding simple seed the pair state repeats within the first 81 steps, and the entropy takes only 6 distinct values (0, 0.503184, 0.783805, 0.833805, 1.060303, 1.121928). The late range is 1.121928 and the smoothed series drops 19 times, so the orbit is not monotone, but it missed the locked bars of 15 distinct values and no short repeat. The mean moves from 0.727726 to 0.689533, which is not a systematic rise. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/evidenceAgainst Rule 0R takes 2 distinct values, so the control is simple. Rule 90R on this ring is not entropy-flat (21 distinct values); it was not the control. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/evidenceAgainst The block seed was pre-registered as a report, not as the verdict. On that seed, rule 37R takes 279 distinct values, drops 44 times, and the mean rises from 2.072965 to 2.628999. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/expectedObservation On the simple seed, rule 37R has late entropy range at least 0.35, at least 15 distinct values, and at least 5 smoothed drops of 0.05, while rule 0R has at most 4 distinct values and every locked round trip returns to its start. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/failCriterion Pre-registered. Refutes if the controls pass and rule 37R on the simple seed either takes at most 4 distinct entropy values, or rises systematically: fewer than 5 smoothed drops, late range below 0.20, and mean of the last 100 values exceeds the mean of the first 50 by at least 0.5. Any other controlled outcome is mixed. A failed round trip, a short repeat of 37R, or rule 0R taking more than 4 distinct values makes the verdict inconclusive. This is a finite ring and 400 steps, not the book's multi-hundred-million-step example, and it says nothing about organisms. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/hasConfidence 0.6 https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/hasEvidence https://w3id.org/delphi/resource/evidence/wolfram2002-ch09-05--claim-test--dataset-1 https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/hasVerdict mixed https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/hypothesis On a periodic ring of width 40, second-order rule 37R started from a single black cell fluctuates in 3-block entropy over 400 steps, while rule 0R on the same ring takes at most four distinct entropy values. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/inferenceMethod Compare the locked summaries of the simple-seed 37R trajectory with the locked thresholds, after the round-trip and the 0R distinct-value control.

Second-order step, from the NKS note on page 1017: (previous, current) -> (current, previous XOR elementary(rule, current)), periodic boundary, width 40, 400 steps. Entropy h_t is the Shannon entropy, in bits, of the 40 overlapping 3-cell blocks of the current row, recorded at t = 0..400 and rounded to 6 decimals. The verdict uses the simple initial condition only: previous all white, current a single black cell at the center. Supports if the late range max(h[200:]) - min(h[200:]) is at least 0.35, the 10-step moving average drops by at least 0.05 at least 5 times, the trajectory takes at least 15 distinct values, the pair state does not repeat within the first 81 states, round-trip of 30 forward and 30 backward steps restores the simple, block, and fixed third initial conditions for rules 37, 0, 90 and 122, and rule 0R on the simple seed takes at most 4 distinct entropy values. The block seed (center bits 101100111000) and rules 90R and 122R are reported and do not decide the verdict. https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/ontology/preregistered false https://w3id.org/delphi/resource/claim/wolfram2002-ch09-05 https://w3id.org/delphi/ontology/hasAssessment https://w3id.org/delphi/resource/assessment/wolfram2002-ch09-05--claim-test https://w3id.org/delphi/resource/evidence/wolfram2002-ch09-05--claim-test--dataset-1 http://purl.org/dc/terms/description entropy trajectories;
