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. parse parses full HTML document into an AST with document, doctype, html, head, and body nodes
  2. parse extracts element tag names, attributes, and child text nodes accurately
  3. parse captures source code location info when sourceCodeLocationInfo option is enabled
  4. serialize converts AST document nodes back into compliant HTML string representation
  5. serialize reflects AST tree modifications such as updated attribute values and appended child nodes
