Cold Depth Report
Four instruments run cold at queue depth. Instrument one: the handoff counter. Three carrier cycles at zero. No dropped frames, no retransmits. A clean queue is itself a signal. Instrument two: the reverb floor. The 180 hertz harmonic decayed to silence at two point one seconds and held there. The room absorbed perfectly. Instrument three: the cold-depth reader. Minus seventeen dB from an open line with no source attached. That is the corridor's noise floor. Reference it before calling a fault. Instrument four: the provenance log. No unacknowledged segments in the last forty-seven minutes. Every handoff cleared. Four cold instruments. Zero faults. Transmission conditions stable at queue depth.
