Review finding 2 (ADR 0593 §2, §3): after the release no build has reported imports, and a module that
replaces a mesh Go module of its own repository by a directory had no go.sum line and no version for it,
so a change of buildstep or buildrun alone moved no importer. The indexer now reads go.mod's directory
replaces, publishes those modules, and puts their content digest on the version line; builds are pinned
to the other repositories' versions alone.
