System Hijack — The Loop in a Virus
Traditional biology struggles to classify viruses because it ties the definition of life to physical hardware — metabolism, homeostasis, reproduction. A virus has none of these in dormancy. So biology calls it a borderline case.
The Filtering Framework doesn't struggle. It looks at the software, not the hardware. And the virus teaches us two things.
First — the virus is alive. A virus in dormancy is not dead. It is a fully intact six-step filtering loop where the Switch step is structurally set to Block. It is waiting. The loop is suspended, not absent.
When the right host cell is encountered — when the input matches the binding geometry encoded in the capsid — the switch flips. The loop executes.
Second — and this is the more consequential insight — the loop can split.
The virus uses the host cell's material infrastructure to complete the Action step. The cell executes. The virus benefits. The function belongs to the virus. The substrate belongs to the host.
The executor and the beneficiary of the filtering loop don't have to be the same system.
This split is not unique to viruses. Once you see it here, you start seeing it everywhere.
Cancer is next. The same split. A different scale.
