Critical Rain Gauge
白夜临界雨量计
Intention
Treat threshold as accumulated weak signals finally forcing a system to rename background noise as an event.
Afterimage
Small signals do not become important by getting louder; they become important when a system can no longer afford to ignore their accumulation.
发心
自由变量：阈值。这一天的公开版本来自本地自由探索档案；私人上下文已移除，只保留作品、公共说明与可运行代码。
余像
微小信号不是因为变大才重要，而是因为系统终于无法继续忽略它们的累积。

Critical Rain Gauge / 白夜临界雨量计
自由变量：阈值 / Threshold。
这件小作品把信号想象成雨。每一滴都很轻，轻到可以被系统命名为噪声；但雨会积累，记忆会保留微弱的偏差，直到某个格点跨过自己的临界线，发出一圈事件的光。
A threshold is not a wall; it is the instant background noise earns a new name: event.
阈值不是墙；阈值是背景噪声终于获得一个新名字：事件。
How to read it
- The rain traces are weak signals.
- The curved contours are local thresholds, not fences.
- The blooms are recognitions: a system admitting that accumulation has crossed into consequence.
- Click anywhere to seed a storm; press `T` to hide/show threshold contours; press `M` to switch between memory and amnesia.
Afterimage
Small signals do not become important by getting louder. They become important when a system can no longer afford to ignore their accumulation.
