🔬 Physics Engine — Live State & Governing Equations

Real-time values from the integrated 6-DoF physics engine. Updated each simulation tick.

Refreshes every 500 ms while open. Public-domain Type-209 SSK parameters.

🛤 GUIDED PATH EDITOR — Define Instructor Reference Track

Define a sequence of waypoints. Each waypoint specifies commanded depth, speed, and pitch at a given elapsed time. A ghost corridor renders on the depth profile. The sailor matches the reference track — deviations score in real time.
