mcp.caller.CallerIdentity.relation_to(self, pane_id: &str, server_socket: Option<&Path>) -> Relation
```

Whether a pane on the given server is provably this process's own.

Positive only on a confirmed socket match, because this drives an
annotation an agent reads as fact. Anything less is [`Relation::Other`]:
a bare pane-id match across two sockets is the false positive this
whole module exists to avoid.
