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
- expand expands comma-separated alternatives within curly braces into string combinations
- expand expands numeric and alphabetic sequences with optional step increments
- expand expands nested brace patterns and computes Cartesian products for adjacent brace groups
- expand handles numeric sequences with zero-padding and reverse ordering
- expand returns an empty array for empty input and preserves literal text when no braces are matched
- expand supports max and maxLength options and exports EXPANSION_MAX and EXPANSION_MAX_LENGTH constants
