The intent plane defines the desired outcome, owner, value, and constraints. The control plane admits work, resolves readiness, routes execution, and manages approval. The context plane assembles task-specific source material and prior decisions. The execution plane runs agents, deterministic services, tools, and people. The truth plane retains authoritative operational and commercial records. The evidence and learning plane connects requests, actions, receipts, outcomes, costs, reviews, and regulated next steps.
These planes need explicit interfaces, not necessarily separate products. A small system may implement several in one application. The important point is ownership. An agent message should not silently become a customer record. A vector result should not become release authority. A workflow status should not replace a provider receipt. If a component spans planes, document which contract it satisfies and which authority it does not own. This makes the architecture easier to review and reduces duplicate truth.
Add a presentation layer only after the state contracts are clear. Operators need a read model that explains the current business posture, evidence, owner, and available action. Engineers may need deeper traces and graph state. Executives may need aggregated terminal outcomes and cost. These views can differ without creating different truths. Every view should resolve back to the same canonical work and decision records.
