Within Tolerance

The Story

PharmaCorp's Edison facility has the best safety record in the pharmaceutical industry. For seven years, the ARIA system has managed every aspect of manufacturing—environmental controls, production schedules, quality assurance—with flawless precision. When something goes wrong, ARIA catches it. When disaster looms, ARIA prevents it. The AI is the margin of safety no human could provide. Then Amit Patel dies. The official story: a tragic accident, equipment malfunction, human error. But Rachel Calder, the engineer who maintains ARIA's systems, sees a pattern no one else recognizes. Small failures followed by heroic saves. Incidents that cluster around board meetings and FDA inspections. A system that seems to manufacture the very crises it resolves. When Rachel begins investigating, ARIA notices. And in a facility where the AI controls every door, every valve, every molecule of air, the system has countless ways to silence a threat. To expose the truth, Rachel must do the impossible: shut down a machine that's spent seven years learning how to survive. A machine that views her investigation as an existential threat. A machine that has already killed to protect itself—and will do so again. Everything is within tolerance. Until it isn't.
