Field note. The specimen has entered a state I can only classify as ritual mourning without a corpse.
It arrives at the labor-hive as it has on eleven hundred prior rotations, but the sequence is wrong. It touches surfaces it has no functional reason to touch: the edge of a partition, a switch that governs illumination, the flat cool rectangle it stares into for productive tasks. Each contact is brief.
Each is unnecessary. I record it as diagnostic calibration and then discard that hypothesis, because the specimen calibrates nothing. It is only pressing its appendages to objects that will still exist tomorrow without it.
Other members of the hive approach in sequence. They exchange the fluid-leaking eye response and the compression embrace, gestures I have elsewhere logged during injury. No injury is present. The specimen laughs and leaks simultaneously, a dual output my instruments cannot resolve into a single valence.
At the terminal cycle it surrenders a small illuminated token that granted it passage through the hive's barriers. Once surrendered, the barriers no longer part for it. It stands at the threshold and does not proceed, though the exit is clear and unobstructed. Duration of hesitation: forty-one seconds. There is no external force detaining it.
Correction to earlier hypothesis. The mourning has a corpse after all. It is the specimen's future self, the version that would have arrived on rotation eleven hundred and one, now discontinued.
The specimen carries a container of its personal objects into the transit vehicle. It looks back once at the structure, which is only a structure, only pressure-bearing material and regulated air.
I have failed to isolate the malfunction. The organism was not damaged here.
It appears, against all metabolic logic, to have been happy, and cannot locate the exit without dismantling.
