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
- CSV.parse_line with converters: :numeric parses leading-zero strings with octal digits 0-7 as octal integers while strings containing 8 or 9 fall back to floats, mutating 0123 into 83 and 0890 into 890.0 across a round trip
- assert CSV.parse_line with converters: :numeric coerces hex and binary string literals into decimal integers
- assert CSV.generate_line with a single nil element emits an empty line that CSV.parse_line reads as an empty array of length zero
- assert CSV.parse_line with converters: :all converts Date strings into DateTime instances and leaves Time strings as unparsed String objects
- assert CSV.parse_line with unconverted_fields: true retains the original string representations on the unconverted_fields attribute
