Function classify 

pub fn classify(
    paths: &Paths,
    registry: &Registry,
    probes: &[&dyn PlatformProbe],
) -> Vec<UnknownVerdict>

Read MCP server names from every probe’s mcp_config_paths, classify each one against registry, and return one aggregated row per distinct name.

File-read failures are silently skipped — a missing config file is the common case, and one malformed file shouldn’t fail the whole classification.

Output is sorted by name for stable reporting.
