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(url) percent-encodes unencoded characters in a URL string
  2. encodeUrl(url) preserves already valid percent-encoded sequences without double-encoding
  3. encodeUrl(url) percent-encodes invalid percent sequences
  4. encodeUrl(url) preserves standard URL delimiters and structural characters
  5. encodeUrl(url) replaces unmatched surrogate pairs with the unicode replacement character before encoding
