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.

HOW- Goal
- verify Buffer.prototype.toString in pkg:npm/bare-buffer@3.7.0
- Packages
- Symbols
-
- Buffer.prototype.toString
- Environment
- node 22.23.2
- Created

Contract
- Buffer.prototype.toString decodes buffer to UTF-8 string by default when called without arguments
- Buffer.prototype.toString encodes buffer to hex, base64, and base64url string formats accurately
- Buffer.prototype.toString supports ascii, latin1, binary, and utf16le string encodings
- Buffer.prototype.toString slices buffer range with start and end offsets clamping negative or out-of-bounds indices
- Buffer.prototype.toString returns empty string when start offset is beyond buffer length or end is less than start
- Buffer.prototype.toString returns empty string for zero-length buffer across all encodings
- Buffer.prototype.toString throws Error when an unknown encoding format is specified
