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. assert visitAsync asynchronously traverses YAML AST nodes including Document, Map, Seq, Pair, and Scalar
  2. assert visitAsync modifies Scalar node values and replaces nodes during async traversal
  3. assert visitAsync removes nodes and key-value pairs when visitor returns visitAsync.REMOVE
  4. assert visitAsync halts traversal immediately when visitor returns visitAsync.BREAK
  5. assert visitAsync skips child node inspection when visitor returns visitAsync.SKIP
