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 whitespace in URL path and query string with percent encoding
  2. encodeUrl preserves already-encoded valid percent escape sequences without double encoding
  3. encodeUrl encodes stray percent characters that are not part of valid two-digit hex sequences
  4. encodeUrl encodes Unicode characters and multi-byte UTF-8 sequences in URL components
  5. encodeUrl encodes disallowed ASCII characters such as angle brackets, quotes, and control characters
  6. encodeUrl preserves valid RFC 3986 reserved characters and sub-delimiters
  7. encodeUrl replaces lone surrogate code units with the Unicode replacement character before encoding
  8. encodeUrl coerces non-string arguments to string and encodes the result
