When scanned, the codes don't just reveal an inventory; they display a chillingly precise, chronological log of when and how the item was last used. The true horror begins when Garrison finds a barcode on his own toolkit, realizing his arrival was anticipated and logged.
Then, a scan of a heavy brass fireplace poker reveals an impossible, future-dated entry: it is scheduled to be used for "blunt force trauma" in exactly twenty minutes.
The system isn't just recording the past—it is dictating the immediate future. When a polite, unnervingly calm man arrives not to browse, but to systematically gather a plastic tarp, industrial bleach, and a hacksaw, the smart-security system deadbolts the doors. Trapped inside with the executioner of the algorithm, Garrison realizes he cannot rely on logic or instinct to survive. The system already predicts human reactions. To live, he must deliberately break the predictive model, turning a meticulously organized house into an unpredictable, chaotic trap.
