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. customTags defines scalar tag with resolve function to parse custom types in parse
  2. customTags uses identify and stringify to serialize custom objects in stringify
  3. customTags parses custom tagged nodes within parseDocument AST
  4. customTags supports multiple custom tags in a single parse call
  5. round-trip serialization and deserialization preserves custom data types with customTags
