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
- Buffer.prototype.writeUInt16BE is a function aliasing Buffer.prototype.writeUint16BE
- buf.writeUInt16BE(value) defaults to offset 0, writes big-endian 16-bit unsigned integer, and returns offset + 2
- buf.writeUInt16BE(value, offset) writes 16-bit big-endian unsigned integer at specified byte offset
- buf.writeUInt16BE masks values exceeding 16 bits to lower 16 bits
- buf.writeUInt16BE throws RangeError when offset is out of bounds, negative, or non-integer
- buf.writeUInt16BE throws TypeError when offset is not a number
