置信度是系统对某个判断"有多大把握"的打分，通常用百分比表示，分数越高代表多条线索同时指向同一个方向。Confidence is a score — usually expressed as a percentage — that shows how strongly multiple independent signals agree with each other on a given assessment.
它告诉你一个结论背后有多少条证据在同时撑场：60% 意味着线索零散、分歧不小；90% 意味着大多数维度都在说同一件事。看这个数字，能帮你区分"有点苗头"和"信号比较集中"。It tells you how many independent pieces of evidence are pointing in the same direction: a score near 60% means signals are scattered and mixed, while a score near 90% means most dimensions are aligned. This lets you distinguish a faint hint from a genuinely concentrated signal.
