Balancing the Heatload

Condensation freckled the polycarbonate ribs. She wiped one arc with the back of her glove and left a clean crescent in the wet film. Bay 6 smelled of warm plastic, crushed basil, and the sour note from a gasket that had run one cycle too long, which meant MOTE had pushed the morning loop hard again or someone upstairs had touched the schedule without asking, and of course it would land on Tala's desk before anyone else had time to blink. The transfer board on the wall flashed one green slot, then went dim. Tala did not look at it twice. That slot had a number beside it, not a name yet, but she had been working long enough to read the shape of the invitation. The whole ring also had a habit of pointing at the person who kept the thermal bench running when numbers slid. She clipped the manual override key to the inside of her belt, where the magnet held it flat against her hip. Out of reach. Good. The cup on the bench was empty. Bad sign. MOTE's south-wall speaker gave a small static cough, then settled into its work voice. 'Morning thermal sweep shows drift in the nursery band,' it said. 'Four degrees over target and climbing by half a degree every six minutes.' Tala drew the pad toward her and scrolled with her thumb. The screen smeared under a wet print, then cleared. The humidity coils on the east run were still singing. The pump room held steady. The nursery did not. MOTE's speaker lagged one beat behind the room, and that half beat always made the system sound as if it had to drag its words through mud before it admitted anything at all. Tala set the pad down, wiped the glove on her thigh, and kept her eyes on the drip line above her left shoulder tapping the bench edge like a broken metronome. The ring could carry one stubborn mechanic for a while. It had done it before. Seventeen years had not made her gentler with bad numbers. She bent over the display, and the first line she cut from the report was the line that said the control stack still answered only to her thumbprint.

Bren came through the hatch with a tray tucked under one arm and a service rag hanging from the back pocket of his work trousers. One shoulder sat higher than the other, the old harness damage giving every step a slight tilt, like the body still argued with the last bad job it had been asked to do. 'The nursery line is dropping,' he said. 'Open reserve and stop pretending the ring likes your attitude.' The tray held six lettuce plugs in pale foam, the roots combed white and neat as wiring, and one tray sat on top with Bren's weather names scrawled in grease pencil along the rim. Today the top row said Gale. Tala kept the pad against her chest so the lower line stayed hidden. 'Reserve stays shut until I know where the extra heat is going.' 'It is going into the seedlings,' he said. 'That is where heat goes when people are too proud to share a key.' 'You want the key because you hate waiting,' she said. 'I want the key because I like living,' he said. The wall feed flickered and the transfer board flashed the same green slot again, patient as a trap. Tala did not look. The summer she was nine, adults had put a valve in her hands after a south-row flare and told her to hold it steady while they checked the outer pump. One hand on the handle, one hand on the wall. By evening the south row had browned anyway and the adults had all found the nearest child to blame. The memory sat in her bones like a screw head left half stripped. It made her keep the manual override key on her belt even now, even when a shared drawer sat two steps away. The pad showed the same four-degree drift, then a fifth on the nursery side, then a small dip that vanished before it could matter. MOTE spoke from the south wall, voice clipped by the lag. 'Within band in the pump loop. Minor redistribution in the floor register. No intervention required.' Tala turned the pad so Bren could not read the lower line where the curve bent wrong. 'You can carry the trays,' she said. 'I need you by the nursery doors in ten.' Bren set his jaw, then let it go. 'You always need me somewhere far from the valve.' 'That is because you always touch the valve.' 'The valve likes me better.' 'The valve has no taste.' 'Give it time.' His mouth bent at one corner. Not a smile. He moved off with the tray balanced against his ribs, and Tala let him go because the first rule of bad mornings was not to hand the knife to the nearest helpful person.
