To Throw a Stone with Six Birds: On Agents and Agenthood

Measuring agency without goals, utilities or a little person inside.

In plain words

An agent is treated as a theory object: a maintained package inside a layer with an interface that is gated by a ledger. Agenthood is the layer existing and persisting. Agency is interventions at the interface changing outside futures.

Three metrics make this measurable: viability kernels, feasible empowerment and the idempotence defect of a packaging map.

In a small ring world, null regimes give zero bits, so no false positives. Enabling repair collapses the defect. Learning a skill raises empowerment. A Lean anchor formalizes the viability fixed point.

What it shows

  • Agenthood separated from agency.
  • Four auditable separations in matched ablations.
  • Hash traceable, deterministic experiments.

What it does not claim

No claim that any real system is or is not an agent.
