Then the same oddities surfaced in devices linked to accounts that didn't exist—burner IDs, ghosted numbers. He traced the anomaly to supply chains: a specific recycler, a particular batch of SD adapters. His report landed on the desk of a regulator used to dealing in binaries and blacklists.

Not all stories the repack carried were triumphant. Some threads ended in silence—the trail broke at an unmapped border, or a voice stopped mid-sentence. Lina kept them too, a quiet guardian of unfinished sentences. The fragments mattered simply because they existed; someone had tried to hold on. Then the same oddities surfaced in devices linked
