A safety case isn't a stack of independent documents — it's a web of shared equipment, shared exposure groups, and shared dependencies. See it as one, and click through any of it.
Focus a shared safety measure to see every fault sequence that leans on it. Focus a fault to see every barrier it credits. Focus an exposure group or a risk category to see every fault that can affect it, or that shares the same outcome. It's the same underlying data as the fault sequence diagrams — just re-centred on whatever question you're actually asking.
The most dangerous single points of failure are the ones that don't look like one — a piece of equipment quietly relied on by three different fault sequences that were written up separately and never cross-checked. The connections map makes that sharing a first-class, clickable fact instead of something you'd only catch by reading every document cover to cover.
Each linked item carries its own line out to its substantiation status, so you're never more than one glance from "has this actually been demonstrated yet."
