Why These Connect
The narrative assertion
"The Doctor's realization that the source is Earth (beat_59c70706ef3a61cb) leads to the TARDIS materializing on Earth (beat_18e4ebf77a7ab9a0), confirming the temporal link between the scan's detection and the Doctor's physical arrival."
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.
