Why These Connect
The narrative assertion
"The alert about the aft transom shutter being opened (beat_9c0281d443b3a2e3) directly leads to Stevenson and Lester discovering the tampered shutter door (beat_9ed7663cd3903b98). This establishes the presence of an intruder (Kellman) and escalates the immediate threat."
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.
