What is Execution?
Execution — Where an agent's decision becomes a real-world action with consequences.
Execution is the primitive that answers where does a decision become an act? It is the point an agentic system stops reasoning and starts doing, where intent crosses into consequence.
It is the layer where authorization, governance, and accountability converge. Because this is where action actually happens, it is the point that most needs to be named and controlled.
Where execution sits in the stack
In the four-layer architecture of the agentic web, execution is a Meta-category (L3) concept — it consolidates fan-out within a category. See the thesis for how the layers compound.
