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. createPacResolver generates an asynchronous FindProxyForURL function from PAC script string or Buffer
  2. FindProxyForURL resolves proxy directives using built-in sandbox helpers including isPlainHostName, dnsDomainIs, shExpMatch, and isInNet
  3. createPacResolver accepts custom sandbox functions passed via options.sandbox
  4. FindProxyForURL accepts both string URLs and WHATWG URL instances with optional host overrides
  5. FindProxyForURL rejects with TypeError when host cannot be determined
