# Glossary

## Common Terms

* **Control Plane**: the server-side capability layer that owns authorization, approval, task orchestration, audit, and delivery control.
* **Bootstrap**: the install and initialization entry phase, not the final formal runtime.
* **Formal Runtime**: the long-running target where services operate as image-based workloads inside K3s.
* **AppSpec**: the unified application delivery input model.
* **Step-Up**: a stronger identity confirmation requirement before high-risk actions.

## Runtime and Governance Terms

* **Session**: the current runtime/session identity used in Agent Platform control-plane and probe contracts, referenced by `agentsession`; not an HTTP session and not a browser login session.
* **Task**: the durable model that records long-running execution state, progress, and result; not an approval record and not a scheduler trigger definition.
* **Approval**: the model that records decision state for gated actions; not task progress and not authorization itself.
* **Gateway**: the sole control-plane boundary in Agent Platform, owning command source, capability registration, routing intent, and global policy authority; not a probe-side worker.
* **Probe**: the host-side runtime worker that consumes authorized commands, manages local channels/adapters, and reports events back to Gateway; not the control plane and not the owner of global policy.
* **Channel**: a runtime communication binding managed by Probe, such as `dialog` or `ssh_remote`; not a session by itself.
* **Adapter**: a runtime integration boundary registered on Probe for tool execution or channel transport; not a scheduler and not a policy engine.
* **Command Envelope**: the Gateway-to-Probe control message wrapper carrying validated command metadata and payload; not an event.
* **Event Envelope**: the Probe-to-Gateway runtime signal wrapper carrying lifecycle, channel, recovery, and capability metadata; not command intent and not a transcript-persistence substitute.
