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
- NimbleCSV.RFC4180.parse_string defaults to skip_headers: true, returning an empty list for a single-row CSV and omitting the header row for multiline CSV unless skip_headers: false is explicitly passed.
- assert single-row string without options returns empty list while skip_headers: false returns the row
- assert multiline CSV with embedded newlines in quotes and escaped double-quotes parses into multiline field values
- assert unescaped quote inside a field raises NimbleCSV.ParseError
- assert RFC4180 parse_string preserves UTF-8 BOM in the first field unless a custom parser is defined with trim_bom: true
