jze9 1029f40318 Fix efficiency metric that could exceed 100% (real bug found by Stage 8 sweep)
A real 5000-run sweep through Docker found the evolutionary optimizer's
best genome reporting efficiency=387%. Root cause: efficiency was
computed as exit_kinetic_energy / capacitor_energy_in, but exit kinetic
energy includes the fixed initial_v_mps launch push (a modeling
assumption, not something paid for by the capacitors) -- for a light
enough projectile, that free energy dominates and the ratio blows past 1.

Fixed by using kinetic_energy_delta (the energy the coils actually added)
instead of absolute exit KE. The per-stage energy identity (energy_in =
remaining_cap + dissipated + kinetic_delta) guarantees kinetic_delta <=
energy_in, so this metric can never exceed 1.0 -- provably, not by luck.
Added a regression test with a light projectile + large initial velocity
reproducing the exact failure mode.

gausse

Симулятор и оптимизатор многоступенчатого электромагнитного ускорителя (coilgun) на реальных, доступных в рознице компонентах.

Полный план и чек-лист этапов — в PLAN.md.

Установка (Docker — основной способ)

docker compose build
docker compose run --rm --entrypoint pytest gausse -q   # тесты
docker compose run --rm gausse sweep --n 1000            # CLI (после реализации Этапа 6)

Результаты (SQLite, отчёты) должны сохраняться в ./results, примонтированный в контейнер как /app/results (см. docker-compose.yml), чтобы переживать пересборку образа.

Установка без Docker (локальная разработка)

python3 -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"
pytest
