THE CATERPILLAR ON THE METAL

Combustion tariff incorporated. Route reserve insufficient. The sentence arrived split into three strips on the forearm of the man, who was asleep in front of the capture with his head fallen to one side. The collective lodging where he waited had also charged for presence. Two housing bookings and a trip now depended on the same open line between his face and Antônio's kitchen. Ilva brought the panel close to the threshold. The presence sensor, a filament set into the wood that measured the vibration of voice and weight to confirm who lived there, had lit up yellow. The affective communication held the house against the team's entry, but the filament was registering the conversation as intermittent. Forty seconds of silence compressed by the model would be enough for the human analysis to call it absence. She bent down. At the bottom of the threshold there was a narrow plate, covered by a film of dry clay. She took a maintenance probe out of the toolbox and slid the tip between the wood and the metal rim. The plate resisted. The probe slipped once and opened a white line in the skin between thumb and index finger. She brought her hand to her mouth, waited for the sting to ease, then went back to the fitting. Nael appeared in the bedroom doorway without his sandals on. Is the man going to come, he asked. She removed the plate. Inside, three thin wires ran to the wall. One was trapped under a crust of earth, brought by the ants from the crack. The sensor received the distant voice, but lost the return from the house. The company could say she was talking from outside in, like a service call, without residence. He'll lose where he lives if he doesn't come, said Ilva. Nael leaned against the door frame. The pequi fenced by the screen appeared in the yard as a leafless stick. A green caterpillar was climbing the metal and stopping where the hot air from the ducts dried the rust. Before, Nael said, the small pequis drew beetles with blue shells. The mine opened the soil above the Lajes, the datacenter began competing for the basin even before it fully existed, and the beetles grew as rare as whole fruit. He looked at the probe in her hand. That thing holds the house up. It holds up the reading of the house. The tariff that had eaten the man's reserve came from gas generation contracted for a datacenter under construction in his city. Route credit had gone up during the night. The industrial flame, far from there, charged passage in Buritaçu with the same precision with which the rare-earth mine charged the plants for shade. Ilva scraped the crust off the first wire. The earth came away in small flakes. On the second, she found a dark film, hardened by heat. She needed to clean it without breaking the sheathing. If the filament snapped, the threshold would open a replacement call and the company would have authorisation to enter. Nael brought a bowl with two spoonfuls of the water reserved for Antônio. She looked at the bowl. One spoonful would be enough. The tip of the probe came away damp. Ilva ran the metal along the wire, slowly, removing the film without touching the core. The yellow of the sensor flickered. The man stirred in the capture, as if he had heard the wood open. Are you there, he asked. I am. The model offered a longer answer, ready to fill the silence. She let the predicted words fade on her skin. Nael crouched beside her. The light of the panel caught his face and showed the dust gathered by his ears. For a few seconds, he followed the work without speaking. Then he asked if she wanted him to take over the voice. The analysis wants two people, she said. Your presence already counts for mine. And his. Ilva finished the second wire. The yellow stayed still. The third remained, crushed by the edge of the plate. She loosened two fixing screws, lifted the rim less than a finger's width and pulled the filament with the probe. The sheathing stretched. The wood creaked. Nael held the plate with both hands. The man began to talk about the trip. There was a connection leaving before first light, then another, more expensive, that required a thermal preparation balance on top of the withheld reserve. He did not ask for money. He told the price the way someone shows a wound under their clothes. Ilva fitted the wire into the track. The sensor turned blue. The threshold recognised two continuous presences. The human analysis lost the right to call the conversation a service. Then another notification climbed the wall. Local maintenance identified. Domestic integrity charge linked to Antônio's address. She closed the plate without tightening the screws too much. The white line on her hand was still open. Nael took the bowl back to the table. The man, in the capture, was asking where he would find Buritaçu when he arrived. Ilva looked at the yard, the low screen, the caterpillar stopped on the metal. You'll see the house before you see the road, she answered.
