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 primitive subclasses bypass the default hook and serialize raw unless OPT_PASSTHROUGH_SUBCLASS is set
- assert dataclasses bypass the default hook and serialize all fields natively unless OPT_PASSTHROUGH_DATACLASS is set
- assert datetime objects bypass the default hook unless OPT_PASSTHROUGH_DATETIME is set
- assert OPT_UTC_Z alone has no effect on naive datetimes, requiring OPT_NAIVE_UTC composed via bitwise OR to emit Zulu format
- assert integers within 53-bit range serialize under OPT_STRICT_INTEGER while integers exceeding 2**53-1 raise TypeError
- assert orjson.Fragment splices raw buffers zero-copy and raises TypeError during dumps if the content is not bytes or str
- assert dumps parameter is singular 'option' raising TypeError on 'options', and invalid bitmasks raise TypeError
- assert OPT_APPEND_NEWLINE writes a trailing newline and composed options execute simultaneously in a single dumps pass
