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.

HOW- Goal
- Demonstrate selective field quoting and iodata streaming in NimbleCSV.dump_to_iodata and dump_to_stream, custom :reserved character quoting in define/2, and multiline row state preservation in parse_enumerable/2.

Contract
- NimbleCSV.RFC4180.dump_to_iodata selectively quotes and doubles escape characters only for fields containing reserved delimiter, escape, or newline characters, while leaving empty strings and unreserved fields bare.
- assert dump_to_stream lazily emits each row as iodata with CRLF row terminators
- assert custom parser defined with :reserved forces quoting for configured characters such as spaces and hashes
- assert parse_enumerable preserves multiline quoted fields across enumerable elements and respects skip_headers
- assert streaming rows through dump_to_stream and converting iodata chunks to binaries roundtrips losslessly through parse_enumerable
