Last Slice

The calibration bay in the upper foodworks tasted like hot metal and sterile yeast. Lira stood ankle-deep in a shallow trough of cooling gel while the conveyor rails below her hummed in patient, obedient loops. Above, the slice-stitching drums turned with a soft, wet rhythm, and every few seconds a thin ribbon of dough-skin rose into view through a viewport as if the world were being plated from the inside.

Her station lights blinked in sequences only she could read - micro-cadences mapped to strands of emotional coding that would be braided into today’s batch. She kept her hands steady anyway. Steady hands were the difference between a perfect delivery and a complaint filed by someone who could still taste their own life. The Oven didn’t forgive inconsistencies; it corrected them the way a mouth corrected a bite - by chewing.

A thin speaker on the wall clicked, then cleared its throat with synthetic sound. “Batch twelve-forty. Target effects: relief, curiosity, cognitive lift. Window: six minutes.”

“Not twelve-forty,” Lira murmured, staring at the oscillograph that traced her calibration output. The line looked right, the waveform too clean. The wrongness lived somewhere else, a hesitation in the system’s certainty. “It’s twelve-forty-one. The strands are shifting by one minute on the lower conveyors.”

The speaker stayed quiet. It didn’t argue. It simply waited for her to be wrong.

Lira pulled a thin calibration strip from its dock and fed it into the reader slot. The strip warmed instantly, as if it had been waiting for her touch. Her gloves squeaked against the panel when she adjusted the emotional coding dial - just a fraction, a hair of phase alignment. In this bay, precision was prayer. She listened to the fans through the soles of her boots, felt the vibration in her bones, and watched the numbers settle into harmony.

On the far side of the glass, a cart rolled past with wrapped sample wedges - taste-probes for quality assurance. Each wedge had its own label, stamped in crisp block letters that never smudged. Margherita Prime. Pepperoni Vanta. Neuro-Supreme. The names were harmless until you remembered what they did. Until you remembered the way people’s faces changed after the first bite, as if their minds had been plugged into a different socket for exactly six minutes, then pulled back out with the gentleness of a surgeon who hated mess.

Lira had always liked the before part. The moment right before the effect kicked in was pure engineering - clean, predictable, controllable. The after part was where the missing lived. She wasn’t supposed to notice it. No one was. Missing was the kind of symptom that got filed under “normal fading” until it became the shape of everyone’s days.

A new alert chirped on her console: micro-deviation detected in strand coherence. The line on the display wavered, then corrected itself. Her thumb hovered over the override.

She didn’t override. She never did unless she had to. She simply rerouted the calibration path through an alternate cache, a trick she’d learned from watching technicians who didn’t last long. It was safer to make the system look like it had always intended the change.

“Batch twelve-forty-one,” she said again, not to the speaker this time but to the air around her hands. “You’ll behave.”

The bay’s lights dimmed a shade as the conveyor accepted her settings. Somewhere below, a latch clicked and the first strands of today’s pizza began to braid into their final patterns. The smell of yeast and warm fat rose through the vents like a promise. Lira leaned closer to the viewport, letting her breath fog the glass for a heartbeat.

Then the fog cleared too quickly.

A sample wedge slid onto the QA rail with a soft thunk. Not a cart delivery - an internal feed, direct. The wedge was unwrapped already, its surface catching the bay lights with a dull, too-even sheen. The label panel beside it flickered, then settled into a blank strip where there should have been an effect designation.

Lira’s stomach tightened. “That’s not logged,” she whispered.

The speaker, finally, spoke again. “Proceed with tasting protocol.”

She didn’t move for a few seconds, because her body didn’t trust the word proceed. The bay’s hum thickened, as if the machine had leaned in. Lira reached for the wedge anyway, because refusing would be noticed. Because her job was to deliver perfection, and the system had teeth.

The wedge was warm. Not freshly baked-warm, but held-warm, like something had been kept under a lamp too long. She touched the crust with the pad of her finger. It was slightly firmer than the others. Her glove squeaked again when she picked it up.

The first bite was supposed to come with a taste signature. Even the “neutral” strands carried a ghost of their emotional coding - salted memory, a hint of nostalgia, a sharpened edge. The bay’s air was full of those expectations....
