Failure risk multiplier
The failure risk multiplier is one plus failure risk cost divided by sync tax, to two decimals. The report prints it only when sync tax is greater than 0; a quarter with no sync tax states its cost in words instead of a ratio.
Failure risk cost is assumed even when nothing broke. Realized break hours are a different thing: they are counted once, inside excess complexity. A quiet quarter still shows the cost of the risk, and a quarter that did break still shows what those breaks cost in engineering hours.
