A channel is not automatically a Scope, WorkThread, or AgentSession.

WorkEvent

Section titled “WorkEvent”

An immutable observation normalized from a provider event, an internal source, or a schedule. Provider-native payloads remain available as raw portable JSON.

AgentScope

Section titled “AgentScope”

A long-lived application-defined governance boundary. It owns shared authority, policy, bindings, subscriptions, memory namespaces, and candidate context. Several channels may map into one Scope; one channel may resolve to different Scopes.

Matter

Section titled “Matter”

The durable identity of the thing being worked on. One Matter may link a Linear issue, GitHub pull request, Slack thread, URL, or an accepted natural-language alias. Unresolved references remain evidence; OpenMatter never invents a provider ID.

WorkThread

Section titled “WorkThread”

The structured continuity of one ongoing piece of work. It may span providers and channels, and remains durable independently of an Agent runtime.

AgentSession and Turn

Section titled “AgentSession and Turn”

AgentSession is a durable binding to an external agent-runtime session. Turn is one invocation inside it. The recommended binding key combines Agent, authority, Scope, WorkThread, and privacy partition.
