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
- Mustermann raises Mustermann::CompileError rather than Mustermann::ParseError when a pattern contains malformed capture names such as empty captures or leading digits, while unclosed groupings raise Mustermann::ParseError and expand with :ignore still raises Mustermann::ExpandError when required keys are missing.
- assert Mustermann.new('/foo/:') and Mustermann.new('/foo/:123') raise Mustermann::CompileError instead of Mustermann::ParseError
- assert Mustermann.new('/foo/(bar') and Mustermann.new('/foo/{bar') raise Mustermann::ParseError with unexpected token messages
- assert Mustermann.new('^/foo', type: :regexp) raises Mustermann::CompileError when anchor characters are present in regular expressions
- assert Mustermann.new('/foo', type: :unsupported_custom_type) raises ArgumentError rather than Mustermann::Error
- assert pattern.expand(:ignore, {}) raises Mustermann::ExpandError when required captures are missing because :ignore only applies to extra keys
- assert pattern.expand(:invalid_behavior, id: 1) raises ArgumentError rather than Mustermann::ExpandError
- assert Mustermann::CompileError, Mustermann::ParseError, and Mustermann::ExpandError all inherit from Mustermann::Error < StandardError
