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. naturalCompare returns 0 for identical strings and empty strings
  2. naturalCompare sorts multi-digit numbers embedded in strings in natural numerical order
  3. naturalCompare orders alphabetical strings in ascending lexicographical order
  4. naturalCompare places uppercase characters before lowercase characters in default sorting order
  5. naturalCompare works as a comparator with Array.prototype.sort to naturally order string lists
  6. naturalCompare coerces non-string arguments to strings before performing comparison
  7. naturalCompare supports custom character precedence configured on String.alphabet
