Task 230: Tech Overview Integrator Comparison + Stats Refresh
Status: DONE
Goal
Add a dedicated integrator comparison section to tech-overview.md explaining the tradeoffs between RK4 (fixed-step), RK45 Dormand-Prince (adaptive), and Störmer-Verlet (symplectic). Also refresh stale statistics and update the DAG viewer description to mention Rust/WASM backing.
Motivation
- DESIGN.md specifies: "TDD で複数の積分手法を実装・比較すること"
- MEMORY.md lists "Integrator comparison in tech-overview" as a potential next task
- Tech-overview currently mentions integrator types but doesn't compare tradeoffs
- Stats are stale (225 tasks → 229, test counts inconsistent, commits outdated)
- DAG viewer description doesn't mention Rust/WASM analysis capabilities
Changes
- Add integrator comparison subsection under Rust core section
- Update progress table stats (tasks, tests, commits)
- Fix inconsistency (body text "350" vs table "377" for Rust tests)
- Update DAG viewer feature bullet to mention WASM-backed analysis
- Fix task count in body text (227 → 229+)
