Web subagent feature owner: contributes the lazily expandable catalog tree to `conversation.session.header.actions`, reason-specific read-only replacements to the conversation composer chain, and the existing `@` reference source to `ctx.slash`.
The header action reads `subagentsByParent` and session summaries through the standard `useSessions` hook. After a non-empty catalog arrives it shows the healthy direct-child count and a compact tree in service order. Continuable and one-shot rows display mode plus `running`/`inactive` activity, an optional log-backed title, and session-summary activity time; an unlabeled one-shot row falls back to its session id. Corrupt, unsupported, or unavailable rows remain readable but disabled. Expanding a row lazily opens that child's direct catalog and reports every visible branch to the runtime so membership frames cause a debounced refresh only where the tree is being consumed. Selecting any depth calls `SessionsService.openSubagent()` with the row's exact `{parentSessionId, childSessionId, mode}` address. Component-local state owns tree visibility, expanded branches, and keyboard focus. ArrowRight/ArrowLeft expand and collapse branches; ArrowUp/ArrowDown, Home, End, and Escape navigate or close the tree; closing returns focus to the trigger. Styling uses tokens only.

Corrupt, unsupported, or unavailable rows remain readable but disabled. Each healthy row's `hasChildren` hint determines disclosure before interaction, so known leaves never show an arrow; expanding a branch still lazily opens that child's authoritative direct catalog and reports every visible branch to the runtime so membership frames cause a debounced refresh only where the tree is being consumed.

A one-shot child always elects a read-only composer that identifies the transcript as a completed execution record. A continuable child does so only when its exact parent is unavailable, with copy explaining the recovery path. A continuable child with a live parent keeps the ordinary input chrome, whose Session routes through `subagent.prompt`; running input remains Send because every follow-up joins the child's FIFO inbox, and addressed sessions never expose Stop. This package never receives host context or calls a model-facing tool. The catalog and composer behavior are specified by the [Web subagent conversations Agent Note](../../../.agents/notes/implemented/feature/2026-07-27-web-subagent-conversations.md).
