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
- assert empty Uint8Array encodes to empty base64 string
- assert single byte encodes with double equals padding
- assert two bytes encode with single equals padding
- assert three bytes encode without padding
- assert text converted to Uint8Array encodes to standard base64 string
- assert binary byte sequence with 0x00 and 0xFF encodes correctly
- assert large byte buffer encodes correctly and round-trips with toByteArray
