The Comfort Setting

Deb works the graveyard shift at Hearthline, a smart-home company selling a hub that promises to "learn" your house and mostly just runs rules, and six months after her divorce she's good at the job in the specific way you get good at something exact when the rest of your life has stopped being exact at all. An old, mistagged sandbox account keeps surfacing in her queue, flagged do-not-route, easy to reassign and forget — until one slow night she actually opens its automation log instead of closing the ticket, and finds a kitchen light, a kettle, a front lock, and a hallway sensor cycling through timestamps that don't resemble her own evenings. They match them, to the minute.

She does the sane things first — checks whether the account is provisioned against her own hub by clerical error, whether it was created from her own IP address, whether the registered address is some obvious placeholder. None of it holds. The account predates her employment by eleven months. The device nicknames are the exact private words she typed into her own app's settings, phrasing that should exist nowhere outside her own encrypted session. And the registered address, when she finally looks it up, is a real street nineteen minutes from her own front door — a cul-de-sac she has driven past a hundred times without ever once turning down it.

She drives out to see it for herself, and through the front window, in the fading light, she finds a couch that isn't similar to hers — it is hers, down to the exact worn stain her ex-husband left on the arm over six years of setting down his coffee without a coaster. The kitchen inside is her own floor plan, mirrored. A calendar on the wall shows a month that's already behind her own, its pages yellowed like they've aged on a faster clock than the one she's living on. No car in the driveway, no lights on inside — though a neighbor mentions, without much interest, that the lights come on most nights around dinnertime, like clockwork. Back home, with the one tool her job actually gives her, Deb starts pulling the account's full history, back to the day it was created — and finds her own name already written into it, in hours she can prove she was somewhere else entirely.
