Why These Connect
The narrative assertion
"The Doctor's instruction to K9 to set a course for Gallifrey using specific binary coordinates directly precedes the TARDIS malfunction, indicating a causal link between the intentional navigation and the subsequent catastrophic system failure. The malfunction's severity is emphasized by K9's confusion and the ship's erratic behavior."
