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 vertical tabulation (\v / 0x0B) serializes to 6-character hex escape \u000b rather than invalid 2-character \v or corrupt bytes (fixed in 3.10.18)
- assert compound strings and dictionary values containing vertical tabs serialize to \u000b and round-trip losslessly through orjson.loads
- assert lowercase \u000b and uppercase \u000B JSON unicode escapes both deserialize to \v (0x0B)
- assert non-standard two-character \v escape sequence in JSON payload raises orjson.JSONDecodeError
- assert standard two-character JSON escapes \b, \t, \n, \f, \r serialize to their 2-character shorthands while all other control characters use \u00XX
- assert positive float scientific exponents serialize with explicit plus sign (+), e.g. 1.2e+30 matching json.dumps (changed in 3.11.7)
- assert integers exceeding 64-bit bounds raise TypeError (JSONEncodeError) with __cause__ is None (changed in 3.10.8)
