Field Notes
Three notable events detected. The strongest occurred at 23:17, where an acoustic anomaly, movement near the north wall, and a heart-rate increase appeared within the same nine-second window. Worth investigating further on a return visit.

Open Questions
- Does the 18–24 Hz acoustic pattern recur at the same hour?
- Was the north-wall movement caused by an external draft source we haven't mapped?
