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. encodeurl encodes spaces and non-ASCII Unicode characters into valid percent-encoded UTF-8 bytes
  2. encodeurl preserves valid existing percent-encoded sequences without double-encoding
  3. encodeurl escapes invalid percent sequences such as incomplete or non-hex escape sequences
  4. encodeurl safely handles unmatched surrogate pairs by replacing them with the Unicode replacement character before encoding
