Context#
The Sci-Fi Hard Vacuum cell promises grounded spaceship simulation with flip-and-burn maneuvers, PDC/railgun/torpedo combat, and gravity-zone changes. Arcade flight would undermine that cell identity.
Decision#
V5 uses a Newtonian flight model for Hard Vacuum ships. Thrust, mass, orientation, recoil, drift, and gravity zones are modeled explicitly, with assist layers exposed as accessibility and difficulty settings rather than a replacement model.
Consequences#
- Ship combat tests must cover inertia and flip-and-burn behavior.
- Input and HUD must communicate velocity vectors and burn planning.
- PvP prediction work must respect deterministic ship-state integration.
