Collapse Watch monitors six civilization-scale risk indices — climate, demographic, energy, financial, governance, AI-mediated — using observable structural indicators rather than headline events. The output is a calibrated reading, not a forecast. Most indices read green-to-yellow most of the time; the index that turns red usually does so months before the discourse catches up. 崩溃观察站监测六个文明级风险指数——气候、人口、能源、金融、治理、AI 中介——使用可观察的结构指标而非头条事件。输出是校准过的读数，不是预测。多数指数多半时间显示绿到黄；变红的指数通常比话语早数月发生。
A leading indicator is a metric that moves before the index moves. Most public risk discourse tracks coincident or lagging indicators (the news, the price, the headline); the structural readings below track upstream metrics that turn 1–5 years earlier.领先指标是先于指数本身移动的指标。多数公共风险话语追踪同步或滞后指标（新闻、价格、头条）；下方结构性读数追踪 1–5 年前转向的上游指标。
