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
- orjson.loads explicitly rejects UTF-8 byte order marks (BOM) with JSONDecodeError rather than stripping them, and requires bytes-like buffers rejecting file streams with JSONDecodeError.
- assert orjson.dumps strictly serializes float NaN, Infinity, and -Infinity to JSON null rather than stdlib json non-standard literal tokens
- assert orjson.loads rejects raw NaN and Infinity tokens with JSONDecodeError adhering to RFC 8259
- assert zoneinfo.ZoneInfo timezone-aware datetimes serialize with exact UTC offsets including daylight saving adjustments
- assert OPT_OMIT_MICROSECONDS strips microsecond precision from both datetime.datetime and datetime.time objects
- assert orjson.loads parses zero-copy memoryview buffer slices without intermediate allocations or copies
- assert orjson.JSONDecodeError subclasses ValueError and json.JSONDecodeError, and JSONEncodeError subclasses TypeError
