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
- parseRange(size, str) parses single byte range and sets type property to 'bytes'
- parseRange(size, str) parses multiple non-overlapping ranges
- parseRange(size, str) parses suffix range relative to total size
- parseRange(size, str) parses open-ended range to end of size
- parseRange(size, str) caps range ending at total size minus one
- parseRange(size, str, { combine: true }) combines overlapping and adjacent ranges
- parseRange(size, str) returns -1 for unsatisfiable ranges
- parseRange(size, str) returns -2 for invalid or malformed range strings
