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
- Parser::parse enforces total stream consumption to EOF and returns Err(ParseError) if trailing bytes remain
- Parser::parse_next performs partial parsing by mutating the input &mut &str slice in-place to the remainder
- take_until consumes up to the target tag without consuming the tag itself and fails if the tag is absent
- alt rewinds stream on ErrMode::Backtrack but halts without fallback on ErrMode::Cut via cut_err
- separated collects items into a collection without consuming trailing delimiters
