Function fillet_edges_reported 

pub fn fillet_edges_reported(
    solid: &BrepSolid,
    edge_points: &[Vec3],
    edge_names: Option<&[String]>,
    radius: f64,
    chamfer: bool,
    name: Option<&str>,
) -> Result<(BrepSolid, BlendSelection), String>

fillet_edges with the selection outcome reported rather than refused.

The result is the same solid fillet_edges would build; the difference is that an incomplete selection comes back as Ok with the misses named, which is the explicit partial-result contract. Every named refusal that applies to the WHOLE selection — mixed concavity, a radius the local wall cannot hold, a mixed-convexity corner — is still an Err: dropping edges cannot rescue those, so a partial answer would be a different defect.
