- Rewrote orbital_mechanics.cpp with complete velocity component handling
- Added proper parabolic case in velocity section using semi_latus_rectum
- Parabolic velocity: vx = -sqrt(μ/p)*sin(ν), vy = sqrt(μ/p)*(1+cos(ν))
- Updated parabolic_comet.toml to use semi_latus_rectum = 2.992e11 (p=2 AU)
- With true_anomaly = 0.0, comet at perihelion (r = 1 AU, v = 42.13 km/s)
Test Results:
- 31 passed / 1 failed (up from 29/3)
- Parabolic orbit tests: All 3 assertions pass ✓
- Position and velocity mathematically correct for parabolic orbits
- Total energy approximately zero (FP precision: ~200 J/kg)
Note: test_invalid_parent_assignment still fails - pre-existing issue unrelated to parabolic implementation.
