• In libraries/math-parser/src/ast.rs, the OfValueAndRegions documentation does not explain that trailing holds the optional last value argument, which may confuse readers; update the field and variant docs to clarify its role.

<violation number="1" location="libraries/math-parser/src/ast.rs:196">
P3: The new `trailing` field is undocumented, and the `OfValueAndRegions` doc comment still describes only "a value and regions" (`within(p, R)`). Readers can't tell this field holds the optional last value argument — e.g. `smoothstep(x, a..b, continuity)`'s continuity parameter — or when it is `Some`. Add a doc comment for the field and update the variant doc.</violation>
