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. Attribute struct holds Namespace, Key, and Val fields representing HTML element attributes
  2. html.Parse extracts element attributes into html.Node.Attr as a slice of html.Attribute
  3. html.Render serializes html.Node with html.Attribute slice into valid HTML attribute syntax
  4. Attribute supports namespaced attributes such as xml and xlink
  5. Attribute values preserve exact strings including whitespace, URLs, and custom data attributes
