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. plist.build serializes JavaScript primitives, objects, and arrays into valid XML plist format
  2. plist.parse parses XML plist strings containing strings, integers, reals, dates, buffers, and booleans
  3. plist.build and plist.parse preserve nested data structures across round-trip serialization
  4. plist.build properly escapes special XML characters in dictionary keys and string values
  5. plist.parse throws an error when given invalid or malformed XML without a plist root element
  6. plist.parse ignores __proto__ keys to prevent prototype pollution vulnerabilities
