The checker's go.mod and go.sum conflicted on the mesh-sdk pin (checker lane 9cb4d59, builder lane e76a5a3): every
module touched is pinned to the sdk lane's newest head d1af87a until the final SDK head.
A TypeScript member of a group that changes mesh-sdk's package resolved the old version from the registry. Its Node
fetch now names the mesh-sdk member's head, which the Node build module packs and serves, publishing nothing. The paths
come from the indexer's modules value (lead decision L8), so a change of Go files or of the manifest alone resolves
the registry as before. A test holds that no step of a check carries publish.
