CH1 定向深挖：风险局部窗口与候选频带

本报告继续做两件事：1）围绕 C 类高频风险文件列出最需要复核的局部窗口；2）提取可用于汇报的候选频带数字。

一、候选频带建议

class	file_count	0_125k_median	0_200k_median	250_1000k_median	400_1000k_median	recommended_interpretation
A_low_frequency_stable	30	99.99%	99.99%	0.01%	0.01%	主候选频带 0-125kHz；500ksps 强支持
B_transition_or_mixed	7	82.26%	83.95%	14.91%	11.85%	候选频带 0-200kHz；需要作为边界样本复核
C_high_frequency_risk	11	48.56%	53.32%	43.36%	34.44%	存在 250kHz 以上尤其 400kHz-1MHz 高频；需现场确认是否目标工况
