 `running` means the exact child Agent driver is draining work at the Host sampling boundary; `inactive` means that driver is idle or absent. The UI does not translate either value into success, failure, cancellation, completeness, or resumability. `subagent.list` supplies the current driver-status baseline, `host/session-status` updates known activity in place, request-local replay prevents an older in-flight list response from overwriting a newer transition, and `host/session-removed` returns a known row to `inactive`; reconnect reads a fresh baseline. A `host/session-added` frame for a direct subagent immediately flips any loaded parent row to `hasChildren: true`, and that positive hint survives an older in-flight catalog response; membership, labels, mode, diagnostics, and the authoritative snapshot still require a debounced `subagent.list` refresh while the affected branch is open. A prompt response remains delivery-time authority.
 
+Healthy rows reuse the standard session projections retained in the list mirror. The token figure sums the four disjoint `tokenUsage` buckets across the durable log. `subagentTiming` resets at every descriptor so an inherited fork seed cannot enter the child's total, accumulates completed `turn/start` → `turn/end` spans, and carries the current turn's `activeSince`. The menu formats whole seconds and advances its local clock only while a known descendant is running; an inactive row uses settled duration, or the summary's last activity to bound an interrupted open turn, so reopening the menu never restarts completed work. Token chunks do not change `subagentTiming` and therefore do not add a per-token list update path. Neither metric implies a durable outcome.
+
 Selecting a row records its exact address before opening the resident client `Session`. History pagination, event folding, tool render intents, titles, and live mux reconciliation reuse the ordinary conversation machinery. Breadcrumbs use catalog labels, follow parent links only through `origin: 'subagent'` rows, include the first ordinary owner, and keep ordinary forks single-level. Forking an addressed subagent creates an ordinary fork with direct source lineage and attaches it to the nearest workspace-owning ancestor. The catalog is an ARIA tree with lazy ArrowRight/ArrowLeft disclosure, linear ArrowUp/ArrowDown navigation, Home/End, Escape, and focus restoration.
 
 A one-shot row always replaces the composer with copy explaining that the execution record is read-only. A continuable row does so only while `parentAvailable` is false. When enabled, its Send action admits another FIFO turn even if the child is currently running; it never becomes Stop. Prompt failures retain the draft through the ordinary error behavior.

-The React-free runtime owns catalogs, single-flight refreshes, retained addresses, availability hints, and transport selection. Re-selecting a known child retains its address so navigation cannot silently switch to ordinary session APIs. A missing intermediate breadcrumb address can be recovered from an already-loaded ancestor catalog, but it is not retained for transport and creates no scope until the user selects that breadcrumb. Restored navigation persists the full mode-bearing address.

 Catalogs ride the standard `useSessions` snapshot. Component-local state owns menu visibility, expanded branches, and focus. `ui-conversation` declares the generic header-action list slot and dispatches the current conversation snapshot through its composer chain; it contains no subagent-specific takeover flag. `@deepseek-ai/dsh-client-ui-subagent` registers the catalog action and elects a reason-specific read-only composer from ordinary owner props. Components receive derived props and callbacks, never `ctx`.

 ## Consequences

 - Parent availability, child activity, and `hasChildren` are snapshots. Publication, disposal, another sender, or another process may win after listing; typed prompt failure remains expected.
 - A child may publish between history fetch and mux subscription, so the existing sequence reconciliation also covers the cold-to-live addressed path.
