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 JSON.load invokes its proc in post-order depth-first traversal but ignores the proc return value, leaving parsed elements unchanged unless mutated in-place
- assert JSON.load supports reentrant parsing inside the proc to deserialize embedded JSON strings into parent container structures
- assert JSON::Parser parses only the initial document and raises JSON::ParserError on concatenated documents rather than streaming
- assert JSON.parse duplicate key collisions update the value while preserving the original key's initial index in hash insertion order
- assert JSON.create_id is isolated in Thread.current so mutating create_id in one thread does not alter addition instantiation in other threads
