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
- yaml.safeLoad parses YAML string with scalars, arrays, and nested mappings into JavaScript objects
- yaml.safeLoad handles null, boolean, integer, float, and date types accurately
- yaml.safeLoad throws YAMLException on invalid YAML syntax
- yaml.safeLoadAll parses multiple documents separated by --- in a single string
- yaml.safeDump serializes JavaScript objects into valid YAML format
- yaml.safeDump supports options such as indent and sortKeys
- yaml.safeLoad with FAILSAFE_SCHEMA parses all scalars as strings without implicit type casting
- yaml.safeLoad and yaml.safeDump round-trip preserves object structure and data integrity
