Why These Connect
The narrative assertion
"The Doctor's realization of the second Tardis's exact replica nature (beat_221f5a656fe2f520) directly informs their later discovery that another Tardis is materializing around the police box (beat_cba8903f10b19ab4), as the pattern of duplication becomes clear."
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.
