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
- assert linear mode matches routes in FIFO insertion order, whereas trie mode prioritizes static segments over generic captures, inverting route resolution precedence
- assert crossing the default 50-route threshold dynamically re-compiles the set from linear to trie mode, flipping route resolution precedence
- assert interleaved multi-value registrations on duplicate patterns group together in linear mode and prioritize static routes in trie mode, disrupting chronological insertion order
- assert configuring strict_order: true restores exact chronological registration order across both first-match and all-matches in trie mode
- assert Mustermann::Router dispatches concurrent multi-threaded requests safely without cross-thread state leakage in Rack environment matches
- assert mutating extracted route parameters does not corrupt subsequent or concurrent params calls on the same pattern instance
