Preface

A complete rewrite with one claim: derive the tree, don't draw it.

The method rests on a deliberately restricted internal block diagram of the system, read in a disciplined form built on a fixed set of ports through which signals, energy, and information propagate. From that description the fault tree is derived by following the propagation paths. The central claim: if the ibd is correct, the derived fault tree is complete and correct.
