// command: a named, logically related group of klammer definitions loaded
// together.  The instance holds metadata and the file list only -- the
// klammers themselves live in the Machine's Klammer_registry (one flat,
// additive namespace; the definition modes govern collisions).  Membership
// is provenance, not containment.
