A rule counts when the drop from t = 0 to the mean of t = 109..128 is at least 0.15 on at least three seeds. Rules 170 and 204 are the shift and identity controls.

Interpretation: The non-random feature pre-registered for this claim is an entropy drop from the initial condition, not a count of gliders. 'Many' is at least 64 of the 256 elementary rules. The identity (rule 204) and the one-cell shift (rule 170) are the controls that should preserve entropy; h4 is averaged over four alignments so a shift does not change it by realignment. The test says nothing about organisms. https://w3id.org/delphi/resource/assessment/wolfram2002-ch06-01--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of wolfram2002-ch06-01: supports, confidence 0.8 https://w3id.org/delphi/resource/assessment/wolfram2002-ch06-01--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-ch06-01/result.json https://w3id.org/delphi/resource/assessment/wolfram2002-ch06-01--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-ch06-01--claim-test https://w3id.org/delphi/ontology/admissibleDatasets The 256 elementary cellular automata on a periodic ring of 256 cells, generated by the checksummed script from seeds 601..604, evolved 128 steps.
