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. netns.None returns a sentinel NsHandle whose IsOpen method reports false
  2. netns.Get retrieves an open NsHandle representing the current thread network namespace
  3. NsHandle.Equal detects matching namespace handles and distinguishes distinct handles from netns.None
  4. NsHandle.Close closes the file descriptor and marks the handle as not open
  5. netns.Set rejects an invalid handle such as netns.None with an error
  6. netns.New creates an isolated namespace when privileged or returns a permission error when unprivileged
