NaCl delta high equivalent class formula is inverted #357
Description
Problem
METPO:1000482 (NaCl delta high) has an inverted equivalent class formula.
| METPO ID | Label | range_max | Formula |
|---|---|---|---|
| METPO:1000482 | NaCl delta high | 8 | 'NaCl delta' and 'METPO:2000071' some xsd:decimal[<= 8] |
The class is named "NaCl delta high" but the formula says <= 8, capturing values at or below 8. It should be >= 8 with no upper bound, consistent with the sibling class METPO:1000472 (NaCl range high) which uses >= 8.
Fix
In src/templates/metpo_sheet.tsv, change the equivalent class formula for METPO:1000482 from <= 8 to >= 8.
Impact
Reasoner would classify NaCl delta observations into the wrong bin class.
