Patch three demanded a different kind of patience. The audio track, mostly white noise, hummed with an underlying frequency Mara isolated with an inverse spectrogram. Buried inside was a repeating motif—three notes, then a breath. The motif corresponded to a folk command used in older regional telegraph signals, a private punctuation between two people who didn't want the rest of the world listening. Once decoded, those three notes were a timestamp: a meeting two nights before the footage’s nominal date.
