THE WORN ROTOR

Conditional installation. Household presence required. The blue strip reappeared on the threshold before Renan got up from the box where he had spent the night sitting. The consortium's workshop had released a twenty-six-minute window for the rotor, with the camera open and energy credit deducted from Antônio's address. Renan rubbed his hardened forearm against his trousers. The purple mark reached close to his elbow. He took the box from behind the service cabinet and set it on the floor, where the refrigerated air made a short strip over the cement. The man read the whole notification. They want your voice too, said Ilva. The screen asked for vocal confirmation from the technician, from the person responsible for the house and from whoever held the maintenance. Renan had lost his professional access. What remained was his name in the workshop register, tied to the fan, the delay and the full docking of the shift. The man opened the entry options. The consortium's envoy was still outside, sitting on the step, the visor resting on her legs. Her corporate authorisation glowed green, with no door to cross. There's a passage just for equipment, said Renan. If it opens, they record that I came in. If I speak, they pull the sampling in with it. And if you don't speak. The fan doesn't get the service. Nael was in the kitchen, picking out corn kernels that had escaped from the farinha. Luzia sat facing him and tried to guess which hand held the bigger kernel. She was wrong twice. The third time, she pointed at the empty hand. You're cheating so I'll stay here, said Nael. You close your hand too slowly. He laughed through his nose and left both kernels in her palm. Luzia pushed them across the floor, one against the other, until one fell into the gap in the threshold. Neither of them looked for it. The man brought his face close to the reader. The light ran across his iris and asked him to say the sentence of household maintenance. He stayed silent. The screen offered an alternative written for people in vocal contestation, the same clause the consortium used to postpone the village's complaints. He chose physical assistance without voice capture. The blue strip opened a narrow line, the width of the box. Renan passed the rotor through first. Then he bent down and crossed sideways, without facing the facade lens. The envoy stood up on the porch. That doesn't cover the technician, she said. It covers the part, answered the man. He comes in with the part. The woman requested human review. The panel reported that the utility company's regional manager would receive the request within six hours. The rotor window kept running. Renan opened the side plate of the cabinet. The cables showed along the wall and climbed to the ducts, held by old clamps. He removed the worn rotor, darkened at the edges, and laid it inside the box. The new one went onto the shaft with two dry clicks. The fan began turning before he drew his hand away. The cabinet sucked in the kitchen air. The cold strip advanced two more hands across the floor. The man pulled Luzia behind the table. The girl left the kernels where they were. On the panel, the mining operation issued the stabilisation charge. Three units of household energy, billed to the address. The man had authority for one cycle and could accept or refuse. If he refused, the workshop would remove the rotor and Renan would receive another technical fault. He looked at Ilva. His thumbnail scraped the edge of the panel. The authentication circle grew over his face. He authenticated by iris. The charge went down to his profile and the installation window closed in green. Renan sat on the floor, leaning against the cabinet. For the first time since morning, the fingers of his injured hand opened. The envoy checked her own screen. The compatibility sampling remained blocked, but the address had acquired recurring technical consumption. She kept the visor close to her body. When this cycle ends, the house opens again, she said. The man did not answer. He went into the kitchen and opened the audio panel. There were five pending files, all corrected by the platform, with the pauses trimmed and the breathing levelled. He played the second. He heard ten seconds of his own voice talking about his mother, about a fruit that rotted quickly in the heat, about a street where he had slept sitting up. He stopped before the end. You keep that one until Antônio comes back, said Ilva. I decide. Decide. He marked temporary retention. The panel asked for a reason. He chose household communication in dispute. The platform linked the file to Antônio's future presence and demanded a retention fee, paid with two of the man's voice marks. The vocal credit line shrank on the screen. Four left, said Ilva. He closed the panel without choosing any more. Outside, the envoy received the human review and moved away from the threshold. Renan gathered up the old rotor. In the grey box, the removed part turned slowly by inertia, as if it were still looking for air.
