The PN-2 is a cockroach-sized automaton, 4 centimeters long, that lives inside electronic systems. It enters through ventilation ports, cable conduits, and maintenance access panels, and it nests on circuit boards, power distribution units, and data buses. It does not destroy the systems it inhabits. It introduces errors. Small, intermittent, maddening errors that degrade performance without triggering failure alerts.

A Flicker on a security system causes cameras to skip frames at random intervals — never enough to trigger a recording gap alert, always enough to miss critical moments. A Flicker on a medical device causes dosage calculations to drift by fractions of a percent — never enough to kill immediately, always enough to cause complications over time. A Flicker on a building management system causes temperature fluctuations, lighting malfunctions, and elevator timing errors that make a building slowly, imperceptibly hostile to its occupants.

The PN-2 is Ouroboros's sabotage-for-hire platform. Corporate clients pay to have Flickers introduced into rival infrastructure, degrading competitor operations through a thousand tiny malfunctions that are individually trivial and collectively devastating. The target company's systems become unreliable. Their employees become frustrated. Their clients lose confidence. The decline looks organic — like poor maintenance, bad luck, institutional rot. It is a machine the size of a cockroach eating a company from the inside.

The Flicker is almost impossible to find. It is the same size and shape as the insects that already inhabit GLMZ's infrastructure. It moves when no one is looking. It nests in locations that technicians do not check. When a system is examined, the Flicker goes dormant, producing no detectable signal or behavior. When the technician leaves, it resumes. The average time to detect a Flicker in a compromised system is fourteen months. In that time, the cumulative damage to system reliability is typically irreversible — not because the hardware is broken, but because the operators have lost trust in their own infrastructure.
