Four example Dockerfiles named golang:1.25 while go.mod requires 1.26; the control plane's image takes GO_BASE from the manifest and these did not, so a build that could not fetch a newer toolchain failed at go mod download (found running the lab through the mesh).

# Built here so a machine can be given it by the mesh rather than by somebody putting a binary on

# it. Static and FROM scratch for the same reason the control plane's image is: it is fetched by
|

# digest and run on a machine, and everything in it is something a person would have to audit.
|

# The Go it builds with is the one the manifest pins (build.on GO_BASE), passed by the Makefile and the
|
|
# build machine alike; the default only serves a hand build, and matches go.mod.
