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. expand expands comma-separated alternatives within curly braces into string combinations
  2. expand expands numeric and alphabetic sequences with optional step increments
  3. expand expands nested brace patterns and computes Cartesian products for adjacent brace groups
  4. expand handles numeric sequences with zero-padding and reverse ordering
  5. expand returns an empty array for empty input and preserves literal text when no braces are matched
  6. expand supports max and maxLength options to bound output results
