Deterministic 2D modern battle sim — browser only, zero dependencies
Place Blue/Red fleets — ships, coastal batteries, carriers, fighters — press play. Both sides run the same autonomous AI: radar tracks (not perfect truth), CEC, layered SAM/CIWS, air strikes, and dogfights. Same seed → same battle, every time.
部署蓝/红双方（舰艇、岸基、航母、战机），按播放。双方同一套自主 AI：雷达航迹（非全知）、 协同交战、分层防空、空中打击与格斗。相同种子 → 完全相同的一局。

Short version — details: docs/SIMULATION_ASSUMPTIONS.md.
- Tracks, not truth — quality / uncertainty / age; RCS + horizon scale detection.
- CEC — side fuses sensors; engage-on-remote with short network delay.
- Command — OTC / AAWC auto-picked; AAW sectors; screen stations.
- Posture —
survive→focus→pressure→saturatefrom observed advantage. - Layered AAW — shared SAM channels + CIWS; massed salvos leak.
- THAAD — only high-energy threats (e.g. Dark Eagle); SM-6 is the naval fallback.
- Air — stand-off strike, LO ingress when applicable, A2A, flares, RTB when winchester/bingo/unemployable.
- ROE — free / tight / hold; self-defense always on.
- Damage — ship hits degrade random subsystems; air hits remove one plane.
- End — wipe or mutual offensive exhaustion (draw).
中文：航迹非真值；CEC 共享；OTC/扇区；姿态四档；分层防空；萨德只拦高超；飞机防区外打击/返场；交战规则；子系统损伤；全灭或弹尽和局。
Tips: concentrate ships (CEC + channels) · protect EWR/AFB/CVN · don’t burn SM-6 for strike · coastlines block ships · same seed = same battle.
建议：编队集中 · 护雷达/机场/航母 · 勿滥用 SM-6 进攻 · 注意陆地 · 同种子同结果。

Sim core (src/sim/) is deterministic: one seeded PRNG, no Math.random/Date.now on the hot path. After sim changes, run npm test and check the bench complexity score.
仿真核心确定性：单一种子 PRNG。改 src/sim/ 后务必跑测试与 bench。
