 An agent's CPU is different. The LLM is the system that reads all inputs — including inputs that might be deliberately crafted to alter its behavior. There is no type system, no instruction validator, no hardware mechanism that distinguishes instructions from data. Natural language is the interface, and natural language has no equivalent to a segment fault. This single property cascades into every design decision: memory management cannot just track what is present, it must track what is accurate. Scheduling cannot just detect process termination, it must judge semantic completion. Trust boundaries cannot rely on hardware enforcement, they must be layered architecturally.

 **Communication fidelity** → Structured protocols (A2A's JSON-RPC) wrap non-deterministic semantics in a deterministic transport layer. A further direction: explicitly tagging critical information to distinguish "facts" (cannot be dropped by summarization) from "context" (lossy compression acceptable).
 
+**Determinism** → Traditional software testing rests on a premise: same input, same output. Hard-code the assertion, CI goes green, ship it. When the CPU is statistical, that premise vanishes — the same prompt run twice may yield structurally different responses. Testing strategy must shift from exact matching to statistical validation: sample multiple runs, replace string equality with semantic similarity, replace hard-coded assertions with LLM-as-judge. "Pass" is no longer binary; it is a confidence interval.
