Why These Connect

The narrative assertion

"Duggan’s earlier brute-force attempt to break through a wall in the cellar (though slightly earlier in the timeline), particularly through beat_323fcfe086804508, enforces his method and leads to the final breach revealing the secret room (beat_f1abbc7a229f1589). His physical approach complements Romana’s spatial deduction."

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.
