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
- Faraday::NestedParamsEncoder.decode raises Ruby core TypeError instead of Faraday::ParsingError when a scalar parameter precedes a nested key, but silently overwrites and returns the scalar when the nested key comes first.
- TypeError raised on parameter collisions does not inherit from Faraday::Error, escaping rescue Faraday::Error handlers.
- Faraday::NestedParamsEncoder.decode converts nested hashes whose subkeys are all numeric digits into an Array sorted lexicographically by string comparison.
- Faraday::NestedParamsEncoder.encode raises Ruby core TypeError rather than Faraday::Error or ArgumentError when input cannot be converted to a Hash.
- Faraday::FlatParamsEncoder.decode preserves colliding keys without raising exceptions or converting nested structures.
- Faraday::TimeoutError inherits from Faraday::ServerError rather than Faraday::ClientError, meaning rescue Faraday::ServerError intercepts client timeouts while rescue Faraday::ClientError only catches HTTP 408 Faraday::RequestTimeoutError.
- Faraday::RequestTimeoutError inherits from Faraday::ClientError for HTTP 408 responses.
- Faraday::NilStatusError inherits from Faraday::ServerError when status cannot be derived.
- Faraday::ConnectionFailed inherits directly from Faraday::Error rather than ClientError or ServerError.
- Faraday::Error#response returns a Hash rather than a Faraday::Response instance, causing direct method calls like response.status to raise NoMethodError.
