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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. Trailing characters following a closed quote raise NimbleCSV.ParseError blaming an unexpected escape character rather than reporting unexpected trailing tokens, while unclosed quotes at EOF report expected escape character.
  2. assert passing non-binary collections to parse_enumerable/2 raises ArgumentError rather than NimbleCSV.ParseError
  3. assert passing non-binary values to parse_string/2 raises FunctionClauseError rather than NimbleCSV.ParseError
  4. assert NimbleCSV.ParseError struct contains only a message field and omits line, row, and column metadata
  5. assert invalid UTF-16 byte sequences in NimbleCSV.Spreadsheet raise generic RuntimeError rather than NimbleCSV.ParseError
