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.

Case
HOW- Goal
- http.Request.Header.Set("Host", ...) is silently ignored on the wire, while http.Request.Host sets the transmitted Host header
- Packages
- Symbols
-
- http.Request
- http.Client
- http.Header
- Environment
- go
- Created
- 2026-08-17T01:33:06Z
Contract
- req.Header.Set("Host", ...) does not override the wire Host header sent by http.Client
- req.Host overrides the wire Host header sent by http.Client without populating req.Header["Host"]
- server handler receives the wire Host in r.Host while r.Header.Get("Host") is empty
