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

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. package manifest specifies @esbuild/netbsd-arm64 name, version 0.25.12, netbsd OS, and arm64 CPU requirements
  2. resolves path to bin/esbuild executable within @esbuild/netbsd-arm64 distribution
  3. validates bin/esbuild executable format as 64-bit ELF binary with standard magic bytes, EM_AARCH64 machine architecture, and non-empty payload
