+- **Provider subagents** are child executions owned by Claude, Codex, or OpenCode. They are not inserted into `AgentManager` as managed agents. Providers emit a separate descriptor and timeline stream through `agent.provider_subagents.*`; the client keeps that state outside the normal agent store and merges only the presentation rows into the track. A descriptor's optional `parentSubagentId` identifies its direct provider-subagent parent; an absent value identifies a direct child of the managed agent.
 
 Clicking either kind opens a workspace tab. On compact layouts it opens in a [sheet](explorer-sidebar.md#sheets) over the subagents list instead; the sheet hides the composer and shows the agent's model and thinking as one line in its place (`PaneSubtitle`, the row provider subagents already use), and a Paseo subagent's sheet offers **Open as tab** (the full-screen glyph in the header) to get the composer back. A Paseo subagent tab is a normal interactive agent pane. A provider subagent tab is a read-only timeline pane with no composer, archive, detach, rewind, or fork actions. It shows its own direct children in a subagents track. Both panes use `AgentStreamView`, so message, reasoning, tool-call, and layout rendering stay identical.
