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
- alt falls back to alternative branches on complete slices when a branch encounters insufficient data
- alt aborts with ErrMode::Incomplete on Partial streams on insufficient data without evaluating subsequent branches
- complete_err transforms ErrMode::Incomplete into ErrMode::Backtrack to re-enable alt fallback across streaming Partial inputs
- alpha0 on Partial streams yields Incomplete at EOF unless explicit stream completion is signaled via StreamIsPartial::complete
