Purpose
To outline the technical specifications and activation sequence for a sonar-triggered activation system designed to reactivate dormant Sea Devil bases from a distance.
Significance
The preliminary plans serve as the physical manifestation of the Master's deception, containing deliberate flaws that expose his sabotage intentions while appearing to legitimate naval protocol compliance. The Doctor's ability to spot these flaws transforms seemingly mundane technical documents into a decisive weapon against the Master's plans, allowing him to discredit the villain while positioning himself as an essential collaborator.
