Minimum version selection happens when the go.mod file is updated, so it contains the minimum versions already.

It doesn't happen only later at build time.

For example:

- `go get x@v1.0.0` => Your go.mod contains `x v1.0.0`

- `go get y@v1.0.0` with y having x v1.0.1 as dep => Your go.mod is already updated with the resolved minimum selected version: `x v1.0.1`

This requires using Go commands to manage the go.mod file. If you edit it in a text editor then a final `go mod tidy` will help.
