I agree the data is intriguing and unexplained in this situation, but the idea of alien reconnaissance is still speculation — it’s an interpretation built on two anomalies: the sunward “tail” and the orbital plane. Those anomalies are real, but jumping from them to a deliberate alien mission is a hypothesis, not a proven conclusion. That doesn’t make it worthless — just important to keep the line between observation and speculation clear.
