Downloaded the Hugging Face listing of the FishBase v25.04 parquet tables and the dataset card. For each listed table, read the parquet footer with an HTTP range request and took the column names from that footer. A column counted as scale size only when its name was a measurement of a scale. Counts of scales along the body, the word 'type of scales', otolith lengths, annulus radii and water hardness did not count. Known age required a FishBase age-measurement field such as AgeMin, AgeMax, tmax or AgeMatMin, and reference-number fields were left out. No row values were read. The pass criterion needs one table that has all three variables.

Measured: 0 FishBase v25.04 tables that contain scale size, scale hardness and known age (n = 216). Interpretation: Scaly fish is read as a fish that bears scales, not as every fish. Size is a linear or mass measurement of the scale, not the number of growth rings. Hardness is a mechanical or explicitly named hardness property, not the darkness of a winter band. Known age means an age that was not itself assigned by reading the scale being tested. The claim is that age can be told from both properties together.

https://w3id.org/delphi/ontology/admissibleDatasets
A row-level table of individual fish, or of scales with a fish identifier, carrying known age, scale size and scale hardness. A species list that merely says scales were used for ageing is not admissible. The denominator is the fish in that table, not all scaly fishes.

AgeMin, AgeMax, tmax and AgeMatMin occur in species-level life-history tables. They are not paired with a scale measurement, so they do not meet the pass criterion.

Footer checksums for each table are in derived/fishbase_column_scan.json. The whole parquet files were not downloaded, so those checksums are of the footers that supplied the column names.
https://w3id.org/delphi/resource/assessment/aristotle-ha08-39--claim-test
https://w3id.org/delphi/ontology/evidenceAgainst
HardnessMin and HardnessMax in the broodstock and egg-nursery tables are water hardness. HardBottom and HardCorals are habitat. LengthOtolith is an otolith measurement. None of these was scored as scale hardness or scale size.
https://w3id.org/delphi/resource/assessment/aristotle-ha08-39--claim-test

The denominator is the FishBase v25.04 mirror, not every scaly fish. A paper table that paired known age with both scale size and scale hardness was not fetched.

The only scale columns in these tables are TypeofScales and counts of scales along the body. Those counts are not the size of a scale, and none of the tables has a scale-hardness column.
https://w3id.org/delphi/resource/assessment/aristotle-ha08-39--claim-test
https://w3id.org/delphi/ontology/expectedObservation
In a sample of at least 20 scaly fish with age known independently of the scale reading, scale size and scale hardness both increase with age.
https://w3id.org/delphi/resource/assessment/aristotle-ha08-39--claim-test
https://w3id.org/delphi/ontology/failCriterion
Refute if that table exists, n is at least 20, and both Spearman correlations with age are less than or equal to 0. If only one of the two correlations is above 0.3, the verdict is mixed. If the table has no hardness column, the verdict is inconclusive with reason data-unavailable. Annulus counts, circulus counts and otolith ages are not scale size and are not hardness. FishBase is admissible only when a column is scale size or scale hardness.

https://w3id.org/delphi/resource/assessment/aristotle-ha08-39--claim-test
https://w3id.org/delphi/ontology/hypothesis
Among scaly fishes with known age, both the size of the scales and the hardness of the scales increase with age, so age can be read from those two properties.
https://w3id.org/delphi/resource/assessment/aristotle-ha08-39--claim-test
https://w3id.org/delphi/ontology/inferenceMethod
Spearman correlation of each property with known age. Both coefficients must exceed 0.3 to support. Both at or below 0 refute. One of the two properties missing is data-unavailable rather than a partial pass.
https://w3id.org/delphi/resource/assessment/aristotle-ha08-39--claim-test
https://w3id.org/delphi/ontology/passCriterion
Pass only if one fetched table contains, for the same fish, a known age, a scale size (radius, diameter, length or mass) and a hardness measure (mechanical hardness, a stated hardness class, or mineral content explicitly identified as hardness), with at least 20 fish, and both size and hardness have Spearman correlation with age above 0.3.
