The module-development documents described a manifest the mesh no longer
reads: four languages where the builder builds two, a Go bundle with no
system, a scheduled process the guide never said how to write, the old
kept-data sections as the norm, and the controller as the one refusing.
They now name each part of a module and its manifest form as the
manifest validator, the builder and the node-engine read it, and the
playbook lists where those parts still disagree, so an author writes
the form every part takes.
