The safety layer

Reality Checks

All 19 of them, in full, exactly as they are printed in the book.

A Reality Check is the paragraph in each chapter that says what could actually go wrong, and what to do about it. There are 19 in the book. Every one is on this page, complete — none is folded away, shortened, or held back for anyone.

Each has its own page too, with a plain answer to the question it is really about, why the situation happens, and who to raise it with. Below, they are grouped by the kind of risk rather than by chapter, because that is how the problem arrives.
