[bug\_fix] go: github.com/user/[email protected]: reading github.com/user/repo/go.mod at revision v1.2.3: unknown revision v1.2.3

Ensure the git tag v1.2.3 is pushed to the remote repository. If it was just pushed, wait a few minutes for the Go module proxy \(proxy.golang.org\) to cache it, or bypass the proxy temporarily using GOPROXY=direct for development.

Journey Context:
A developer creates a new feature in a shared library, tags it as v1.2.3 in git, and pushes the commit. They immediately update their main application to use this new tag via go get github.com/user/[email protected]. The command fails with unknown revision. The developer verifies the tag exists locally with git tag and pushes it again, but Go still can't find it. They might delete their module cache or try different tags, suspecting a git corruption. The rabbit-hole is caused by the default GOPROXY=https://proxy.golang.org,direct. The public Go proxy caches module versions, but it takes a short time to discover newly pushed tags, and sometimes it needs a manual cache bump. Alternatively, the developer might have forgotten to push the tag itself \(git push origin v1.2.3\), only pushing the commit. The fix is to verify the tag is on the remote, and if developing locally, use GOPROXY=direct to fetch directly from the VCS, bypassing the proxy cache delay.
