Strange Signals
神秘信号
Radio, acoustic, and other signal anomalies where the record is real but interpretation is contested.
This page collects published case files and developing reports in this category so readers can move from broad patterns into the source-backed cases behind them.
Classification
AI labels category, entities, event names, aliases, evidence, and debunks.
Clustering
Items with matching names, dates, places, and references become one candidate.
Publishing
Only source-backed clusters clear review and become public case files.
