This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- chi.Mux evaluates radix trie route matching in strict node-type priority order: exact static routes match first, followed by regexp parameters, unconstrained named parameters, and catch-all wildcards, regardless of route registration order.
- chi.URLParam extracts single path segments for named parameters, the remaining multi-segment tail for wildcard parameters, and an empty string for unregistered parameter keys.
- chi.Mux.Route builds nested route trees that preserve parent URLParams and construct full composite RoutePattern values.
- chi.Mux.Mount propagates parent URL parameters into mounted subrouters while routing against the remaining relative subpath.
