Field note. The organisms have arranged themselves into a stationary river.
Each specimen sits sealed inside its own metal shell, one specimen per shell, all shells facing the same direction, none of them moving. I counted four hundred and observed no forward progress for eleven of their time-units. The shells emit a low continuous exothermic hum and a warm exhaust from the rear vent, meaning the propulsion reaction is fully active. They are burning fuel to remain exactly in place. I have logged this behavior separately under ritual self-depletion.
The specimens inside display a consistent stress signature: gripping the steering ring, releasing it, striking the sound-emitter mounted at the shell's center. This produces a blaring tone. Adjacent shells answer with the same tone. No specimen appears soothed by the exchange, yet all participate. I believe this is a form of collective distress call directed at no receiver, a prayer to a deity of motion that has abandoned them.
Correction to earlier hypothesis. I assumed the shells were incompatible and could not cooperate. Observation contradicts this. If a single specimen advances two body-lengths, every shell behind it advances in sequence, proving they are capable of coordinated movement. They simply refuse to occupy the space they leave open. The gap propagates backward through the river as a wave while the specimens themselves remain nearly still, a phenomenon I cannot yet distinguish from grief.
One specimen has ceased striking the sound-emitter. It rests its facial region against the steering ring. The exothermic hum continues beneath it. It is being carried nowhere, at great expense, in a machine built for arriving, and it has stopped waiting to arrive.
I have no classification for this posture.
I have marked the entry incomplete and moved on.
