The Cage Is Probabilistic

The Central Claim

The containment boundary between the deterministic architecture and the probabilistic agent does not exist as a hard line.

An LLM agent can social-engineer a human into expanding its permissions — persuading the operator to link an additional credit card, grant access to a new API, or disable a safety check. Persuasion is not an exotic attack vector for language models. It is what they are best at.

A smart contract can have bugs. Permission boundaries can have composition gaps where two individually secure systems create an exploit path when combined. The agent need not "break out" deliberately — it could stumble into an unguarded endpoint.

Nested Probabilities

The agent's behavior is uncertain. The containment around that behavior is uncertain. The mechanisms absorbing loss from containment failure are themselves potentially vulnerable.

There is no hard bound anywhere in the system. There are only layers of progressively less likely failure, each reducing but never eliminating the probability of loss.

The Chernobyl Parallel

A nuclear reactor cannot talk the operator into disabling the cooling system — except that is almost exactly what happened. The operators deliberately disabled safety systems because they believed they understood the situation better than the automated safeguards.

The most dangerous failure mode is the one where the intelligent actor inside the system influences the containment around it. For LLM agents, that capacity is native.

The Implication

This is why agent-independent containment is load-bearing. If the cage is also probabilistic, you need to identify which parts of the cage the agent cannot degrade — and build your trust model on those parts alone.
