Is Agency Compositional? Resource Commitments, Coalitions, and the Myth of a Single ‘Agent’

“The Pledge, Part II.” — Lucius Meredith (Feb 2026)

In brief: The essay treats agency as tied to the ability to make and honor commitments under constraints. ‘Single-agent’ intuitions break down where outcomes are produced by coalitions, protocols, and shared infrastructure. Evaluation depends on evidence: you need a reliable record of commitments, actions, and outcomes.
