Why These Connect
The narrative assertion
"The Doctor and his companions materialize on the Nerva Beacon at the start (beat_8fc53fdbb50e4ed8), which directly leads to his investigation of Kellman's cabin (beat_6277f5eb0f2841c5). The initial arrival sets the Doctor's journey into motion, culminating in his confrontation with Kellman's trap."
About Causal Connections
A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot--remove one and the story structure collapses.
