01关于计算器About the calculator
Meter Gomoku Web 是 Meter Gomoku 项目的网页版本：棋盘、功能键、分析调度、计分与界面由本项目编写；搜索引擎使用 Rapfi（作者 dhbloo，仓库现为 dotb1ue/rapfi）的官方 WebAssembly 构建与 NNUE 权重。所有计算都在本机浏览器完成，棋局不会上传。
Meter Gomoku Web is the web edition of the Meter Gomoku project: board, keys, search scheduling, scoring and UI are ours, while the engine is the official WebAssembly build of Rapfi (by dhbloo, now at dotb1ue/rapfi) with its NNUE weights. Everything runs in your browser and no position is uploaded.

02引擎与算法Engine & algorithms
普通分析使用多主变（multi-PV）：设置里的「分析点数」N 决定同时给出 N 个互不重合的根着法与 N 条路线；搜索加深时 Rapfi 会重排根着法，较早的次优点被更强的点替换，标记与路线随之迁移。扫描分析走独立的候选扫描通道，把大量空点用连续色阶标在棋盘上，再点一次扫描键会停止并落下最优点。
Normal analysis uses multi-PV: the N in “Multi-PV” produces N distinct root moves and N lines. As the search deepens Rapfi re-sorts its root moves, so an early weaker point is replaced by a stronger one and the marker moves with its line. Scan analysis is a separate pipeline that paints many empty points with a continuous colour ramp; clicking the scan key again stops it and plays the best point.
