Task 202: Plasmoid Perturbation Trajectory Analysis

Status: DONE (was already completed in Task 100)

Objective

Estimate trajectory perturbations from plasmoid encounters in EP04, distinguishing radiation effects from momentum effects.

Resolution

This task was already completed in Task 100 ("Plasmoid Perturbation Analysis + Physics Consultation Model"). All 5 scope items are fully implemented:

1. Rust plasmoid.rs module: magnetic/ram pressure model, 3 scenarios (nominal/enhanced/extreme)
2. WASM bindings: plasmoid_perturbation, uranus_plasmoid_scenarios, etc.
3. EP04 report: exploration section "軌道摂動推定（運動量効果 vs 放射線効果）" with 3-scenario comparison
4. Key finding: momentum perturbation is completely negligible (max Δv = 1.6×10⁻¹⁰ m/s at extreme). Radiation (480 mSv) is the sole threat.
5. 11 Rust tests covering all plasmoid physics functions
