[bug\_fix] github.com/myorg/[email protected]: reading https://proxy.golang.org/... 404 Not Found or verifying module: reading https://sum.golang.org/lookup/... 404 Not Found

Set \`go env -w GOPRIVATE='github.com/myorg/\*,\*.internal.example.com'\` to bypass the public module proxy and checksum database for private hosts. Set \`GONOPROXY\` and \`GONOSUMDB\` to the same patterns if you need finer control. Ensure git/SSH credentials or HTTPS tokens are configured so the go command can clone the repo directly.

Journey Context:
You add an internal company module to your imports. \`go mod tidy\` fails with a 404 from proxy.golang.org because the public proxy cannot see your private GitHub organization. You try \`GOPROXY=direct\`, which fetches the module but still fails the checksum check against sum.golang.org. You consider turning off module verification entirely, which is unsafe. The real fix is \`GOPRIVATE\`: it tells the go command which paths are private, causing it to fetch directly from version control and skip the public sum database for those modules. It works because the default environment is \`GOPROXY=https://proxy.golang.org,direct\` and \`GOSUMDB=sum.golang.org\`; private repositories must be excluded from both the proxy and the checksum database, while still being authenticated by your existing VCS credentials.
