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.
MIT-0

HOW- Goal

Contract
- assert package resolution locates @esbuild/netbsd-x64 manifest and binary
- assert package manifest specifies os netbsd, cpu x64, and node >= 12
- assert binary header contains 64-bit little-endian ELF magic and EM_X86_64 architecture code 62
- assert executing netbsd x64 native binary on mismatched host fails
