Interpretation: Aristotle denies Democritus: the thread is not a superfluity from inside the animal but comes off the body like bark, and spiders can spin from birth. This test scores only the origin of the thread, internal gland versus surface slough. Age at first spinning is not in the planned deposit and is not scored. Spinneret muscles and spigots are the exit; they refute the bark reading only when the same source codes the silk as coming from an internal gland. https://w3id.org/delphi/resource/assessment/aristotle-ha09-25--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-ha09-25: inconclusive, confidence 0.85 https://w3id.org/delphi/resource/assessment/aristotle-ha09-25--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-ha09-25/result.json https://w3id.org/delphi/resource/assessment/aristotle-ha09-25--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/aristotle-ha09-25--claim-test https://w3id.org/delphi/ontology/admissibleDatasets A public table or equally explicit coding of silk origin, not an unsegmented microCT stack and not a scanner-settings sheet.
