Commonly assumed
A Mustermann pattern set matches routes in FIFO registration order, preserving chronological evaluation across both linear and trie matcher modes regardless of route volume.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
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
