FIELD OBSERVATION 0413-T Site: Sector 7, westbound corridor Conditions: Twilight, calm, ambient luminosity declining At 19:47 local time, the arrays began their nightly reorientation— not toward the sun, which had already gone, but toward the track. I have no explanation for this behavior. The crystalline facets, designed to follow photon density gradients, have developed what I can only describe as preference. They turn toward the train like sunflowers toward something they've mistaken for the sun. I measured the angle: 12.4° off optimal. Consistently. Every panel. Every evening. The train does not stop here. It has never stopped here. Its schedule is not published. But the panels know when it is coming before I hear the rails sing. I have filed no report. I am not sure this is a malfunction. I am not sure anything that turns toward light can be said to be broken.
