Specimen: the human, in the metal room.
The organism has traveled to the warehouse where its species gathers to lift heavy objects and set them down in the same place. It has completed one such cycle. Now it does something the exertion cannot explain.
It faces the polished vertical plane, the one that emits a duplicate. It arranges its body: torso rotated eleven degrees, one limb braced against the reflective surface, respiratory chamber inflated beyond functional need. It raises the glowing rectangle. A brief flare of light. The duplicate is captured, trapped, preserved.
I have measured the sequence four hundred times. The lift takes seconds. The capture of the duplicate takes considerably longer. The organism reviews the trapped image, discards it, produces another, adjusts the angle of the light source, discards again. It is hunting for a version of itself that does not exist, using a device that can only show the version that does.
Correction to earlier hypothesis. I had logged the plane as a self-diagnostic tool, a means of verifying structural integrity after strain. This is incomplete. The organism does not check whether it is intact. It checks whether it is being witnessed, then manufactures the witness itself, then transmits the manufactured witness to distant members of the colony who were not present and did not lift anything.
The muscle it has just fatigued will regrow. The captured duplicate will not change. Yet the organism guards the duplicate more carefully than the body it copied. It buffers, then sends. It waits, respiration shallow, for the small tokens of acknowledgment to return through the device.
A curious secondary reading here on my own instruments, unclassified: a faint reluctance to look away from the departing image.
I will attribute this to sensor drift.
