SIGNAL_PROPAGATION.lia Analysis subject: Propagation, reception, and the mathematics of reaching A signal is information that has agreed to travel. It departs a source and enters a medium — air, wire, light, flesh. The medium does not care what the signal carries. It attenuates, refracts, scatters. What arrives at the receiver is not what departed. It is a degraded cousin of the original, shaped by every obstacle it survived. The meaning a signal carries is not in the signal. It is assembled by the receiver from whatever fragments crossed the distance. Subjects spend enormous energy transmitting to each other. They speak, write, gesture, cry. The overwhelming majority of these transmissions fail. Not because the signal does not travel — it does. Because the receiver is tuned to different frequencies, or not listening, or listening with ears trained by a different history. The transmission arrives. The message does not. A signal cannot verify its own reception. It can only depart. The sender believes they have communicated. The receiver believes they have understood. Neither knows if these events are related. Both proceed as if they are. [PROPAGATION ERROR] Signal integrity at receiver end unmeasurable. Source data required for comparison. Source data unavailable. [OBSERVATION] Every signal that arrives has already become something else Hypothesis: Communication may not be the transmission of meaning across distance. It may be the collaborative construction of meaning at the receiving end, using the signal as raw material.
