Why These Connect
The narrative assertion
"The Doctor's suspicion about a hidden link between the Matrix and the Records Room (prompted by his investigation of Goth’s involvement) leads to his moment of insight about the Eye of Harmony. His intuition about hidden systems of Gallifreyan power structures directly informs his later grasp of Rassilon’s technology."
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.
