SOURCES & VERIFICATION
We don't take any single directory's word for it. Before scoring, we cross-reference 2 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
The same server, 2 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.

// Counts are directory-reported; we don't adjust them. Discrepancies usually come from different snapshot times or star-caching.
