Hardwired and competency 20, 100 and 400 populations are each run 100 times for 250 generations from fixed seeds. For each Table 1 threshold it reports the first generation at which the mean best phenotypic fitness reaches it, and runs one-sided Welch t-tests of each competent population against hardwired at generations 2, 10 and 20. https://w3id.org/delphi/resource/assessment/levin-2023-competency-04--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/levin-2023-competency-04--claim-test http://www.w3.org/2000/01/rdf-schema#comment Measured: 4 generations for the mean best phenotypic fitness of the competency-400 population to reach 1.0 (n = 100, Monte Carlo; fixed seed, deterministic for a given numpy version). Interpretation: This is a simulation-result claim, so the test is replication: re-run the described model and check that the reported dynamics follow from it. Parameters are taken from Supplement S1/S2.1 of the paper (array of 50 cells, values 1-50 drawn with repetition, 100 embryos, top 10% selected on phenotypic fitness, crossover, per-individual point-mutation probability 0.6, competency levels 20/100/400) and unspecified details from the authors' code (github.com/Niwhskal/CellularCompetency, commit 2be29f96): fitness 9^x/9 where x is the normalized non-inversion count; restricted bubble sort that swaps strictly inverted adjacent pairs, visiting positions in a fresh random order each sweep, up to the competency limit; selected parents are kept and children are added by single-point crossover (cut in [11, 50)) until the population is refilled, then every individual is point-mutated with probability 0.6. 'Reaches a threshold' follows the paper's Table 1: the first generation at which the mean over repeats of the best individual's fitness is >= the threshold. The re-implementation is written independently (vectorised numpy) and does not import the authors' code. https://w3id.org/delphi/resource/assessment/levin-2023-competency-04--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of levin-2023-competency-04: supports, confidence 0.9 https://w3id.org/delphi/resource/assessment/levin-2023-competency-04--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/levin-papers/levin-2023-competency-04/result.json https://w3id.org/delphi/resource/assessment/levin-2023-competency-04--claim-test http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-claude-opus-5-5 https://w3id.org/delphi/resource/assessment/levin-2023-competency-04--claim-test https://w3id.org/delphi/ontology/admissibleDatasets Planned datasets: competency-ga-reimplementation-runs https://w3id.org/delphi/resource/assessment/levin-2023-competency-04--claim-test https://w3id.org/delphi/ontology/assessmentType claim-test/0.1.0 https://w3id.org/delphi/resource/assessment/levin-2023-competency-04--claim-test https://w3id.org/delphi/ontology/dataKind computational https://w3id.org/delphi/resource/assessment/levin-2023-competency-04--claim-test https://w3id.org/delphi/ontology/disconfirmingObservation Pre-registered: at the 0.97 or 1.0 threshold some higher competency level is strictly slower than a lower one (including hardwired faster than any competent level), or a competent population is not better than hardwired at generation 10 (p >= 0.05 or lower mean).

The authors' plotting code counts hardwired crossings from 0 and competent crossings from 1, and their committed configuration uses 10 repeats rather than the 100 stated in the supplement; either could account for small offsets.
