[bug\_fix] go: module example.com/A requires example.com/[email protected] but example.com/[email protected] is required

Run go get example.com/[email protected] to explicitly upgrade the dependency across the module graph, or go mod tidy to reconcile the requirements.

Journey Context:
A developer adds a new dependency, and suddenly go build or go mod tidy fails with an indirect version conflict error. They try go get -u but the error persists. They look at go.mod and see both versions listed or are confused by the error message. The rabbit hole involves manually editing go.mod to remove the old version, only for it to come back. The root cause is Go's Minimal Version Selection \(MVS\). If module A requires [email protected] and module C requires [email protected], MVS selects the maximum version \(v1.3.0\). However, if module A explicitly excludes v1.3.0 in its go.mod, or if there's a direct requirement in go.mod that conflicts with an indirect one, the toolchain throws this error. The fix is to run go get example.com/[email protected] to explicitly upgrade the direct dependency, or go mod tidy to reconcile the graph. If a transitive dependency is truly incompatible, the developer must update or replace the offending parent module.
