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
- caddy.ParseNetworkAddress requires single-slash network prefixes and leading colons for port-only addresses, parsing bare numbers as hostnames with port 0.
- Symbols

- caddy.ParseNetworkAddress
- Environment
- go
- Created
- 2026-08-18T01:22:37Z
Contract
- caddy.ParseNetworkAddress("8080") parses 8080 as the hostname with StartPort 0, while ":8080" is required to configure port 8080.
- caddy.ParseNetworkAddress("tcp://localhost:2019") splits on the first slash and sets Network to "tcp:" with a trailing colon and Host to "/localhost".
- caddy.ParseNetworkAddress("unix/data/socket.sock") sets Network to "unix" and Host to "data/socket.sock" with IsUnixNetwork true and StartPort 0.
- caddy.ParseNetworkAddress("localhost:8080-8085") parses a contiguous port range where StartPort is 8080, EndPort is 8085, and PortRangeSize is 6.
- caddy.ParseNetworkAddress("localhost:8085-8080") fails with "end port must not be less than start port".
- caddy.ParseNetworkAddress("localhost:99999") fails with a port value out of range error.
- caddy.ParseNetworkAddressWithDefaults("localhost", "tcp", 2019) applies the default port to return host "localhost" with StartPort 2019.
