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. imports.Process formats Go source code and automatically resolves required standard package imports
  2. imports.VendorlessPath returns the un-vendored package import path
  3. cfg.New constructs a control flow graph containing entry, exit, and branch blocks for a function AST
  4. typeutil.Map associates arbitrary values with go/types Type keys using type identity
  5. cover.ParseProfilesFromReader parses Go coverage profile data into structured Profile and ProfileBlock entries
