A short story set in Year 3 of the Integration Era.

The overlay is mine. It arrived when I was twenty-nine years old, without my permission, in the middle of a Tuesday afternoon while I was trying to debug a transit routing algorithm that had been wrong for six weeks. One moment there was nothing. The next moment there was everything: six numbers, a designation, a notification in clean geometric script informing me that the universe had taken a measurement.

I know what that felt like. I cannot forget it even when I try.

Tev was born three months after that Tuesday.

He came into the world in a hospital still processing Integration shock — doctors whose overlays were serving them combat skill offers they kept dismissing, administrators trying to determine what designation certification meant for surgical licensing, an entire facility doing its job while a new architecture draped itself over everything and refused to be turned off. The midwife who delivered him, a Specialist-designation woman named Horis, had the contained efficiency of someone who had looked at her stat screen and decided it was going to be a problem for another time. She was the best person in that room. We were all, that winter, the best people we could manage while the world reconfigured.

Tev arrived screaming, as babies do. Red and furious and incomprehensibly perfect. I held him for the first time and the overlay was there in the upper left of my visual field, where it has been every moment of every day since Tuesday, and I thought: can you see that? Then, almost immediately: of course he can’t. He just got here.

But I looked. I admit I looked — flicking my gaze to the upper right, the gesture that would show me an adjacent profile if there was one to see. There wasn’t. His profile, if it existed at all, was dark. Not absent. The way a screen is present when it’s off.

I told Dav about this later, in the particular patchwork quiet of a hospital room at two in the morning with a sleeping newborn between us. He was still fully Dav then, not yet whatever the Vanguard designation was going to require of him, and he laughed and said: “You checked his stats on the way out.”

“I checked if he had stats.”

“Before he was an hour old.”

“The midwife might have checked.”

He laughed again, and I laughed, and it was funny because it had to be, because the alternative was sitting in the dark with a new person who’d never had an overlay while I wondered when it would arrive.

The first year was before the count.

That’s how I think of it now. Before the count. The Integration couldn’t see him, or wouldn’t, or didn’t — nobody knew then and I’m not certain they know now — and so there was a year in which my son was simply a person, unverified, unknown to the system, belonging only to Dav and to me. He learned to hold his head up. He learned to track light across a ceiling. He fell asleep in my arms with the full weight of a small body making its permanent decision to occupy one particular patch of the world, and I learned how heavy a thing can be that you would never want to put down.

I knew it couldn’t last. I’d read the reports. Integration activation in children appeared to follow cognitive development — when the neural architecture reached sufficient complexity to interface with the overlay, the system noticed. The estimate at the time, compiled from pediatric observations across fourteen settlements, was somewhere around eighteen to twenty-four months. Nobody was certain. There were no pediatric Integration specialists because the Integration had existed for less than two years and the specialty had not yet been invented. There were pediatricians doing their best with a situation nothing in their training had addressed, which is to say they were the same as everyone else.

Dav was deployed before Tev turned one. His Vanguard designation had been pulling at him since activation — the combat skill offers, the system prompts, the Designation Rank milestone notifications that appeared after things that looked exactly like what his unit was being asked to do in the outer settlements. I don’t blame the system for this any more than I blame weather for being cold. The system measured something that was already true about Dav, some readiness that had been forming in him for years before Tuesday. I just hadn’t expected Tuesday to make it visible and inevitable at the same time.
