The model option list now de-duplicates entries by value before rendering. Duplicate rows are silently dropped with a warning log entry: "model options: dropping duplicate row [label] (value [value])". Disabled entries are sorted to the bottom of the list, after all enabled options.
Evidence
New deduplication pass (search for "model options: dropping duplicate row")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
