 * - No `when` → always included (retrocompat; existing enums untouched).
 * - With `when`: the gating field is `when.field ?? dependsOn`. If neither is
 *   present the option is included (nothing to gate on). Otherwise the form's
 *   value for that field is compared AS STRING: included when (no `in`, or

 *   snake_case `not_in` the kernel serves alongside camelCase `notIn`.
 *
 * `formValues` is the flat map of the surrounding form/row values the gating
 * field is read from; `dependsOn` is the containing field's declared dependency
 * used as the default gating field.
