ARP Concepts

In this section, we identify a set of core objects and durable artifacts. They help bridge the gap between COP, an engineering mindset, and ARP, a real protocol that's implementable (and indeed implemented as the JARVIS stack.)

Standard vs. implementation

This section explains the shared mental model, a.k.a. what the objects mean and why they exist. For normative schemas and endpoints, see ARP Standard.

Core Concepts​

  • Capabilities and Nodes: what a NodeType is, how NodeRuns are created, and how Runs are structured.
  • Candidate Sets: how Selection returns candidate sets, which are bounded action spaces for planners, and how that limits “what the system can do next”.
  • Policy Checkpoints: how authn/authz and other access policy checkpoints are enforced.
  • Artifacts and Replay: why events and artifacts exist and how they support replay and evaluation.
