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. profile.Profile creates and validates a structured cpu/memory profile with CheckValid
  2. profile.Profile.Write serializes the profile into gzip-compressed protobuf format
  3. profile.Parse parses serialized profile data and restores samples, locations, and functions
