A subagent child row borrowed its parent's `updatedAt` as its staleness clock and set no `evidenceObservedAt`, so the sidebar's "No update in N" label reported the PARENT's silence as the child's. With one child that reads correctly by coincidence — the child's activity is what advanced the parent's clock. With siblings it is wrong: a child quiet for ten minutes reads "No update in 0m" because a sibling just pinged. Reuse `evidenceObservedAt`, the field that already carries this meaning on `AgentStatusEntry` and whose reader already prefers it and already falls back to `updatedAt`. Add it as an optional field on the two child-bearing wire types and stamp it at the producer boundaries that already classify an event as the child's: - Claude hook roster: every child-attributed tool event and the lead's background-task fold. - Codex hook roster: every child-attributed lifecycle and tool event. The stamp takes an explicit observation argument, because two callers (the transcript scan and the restore seed) pass a SPAWN stamp as their creation clock and reusing it would backdate the child's recency to its own birth. - Structured background tasks: `task_started`, `task_updated`, the aggregate roster frame, and — the load-bearing one — `task_progress`. That branch previously dropped a frame entirely unless the task was backgrounded AND the frame carried token usage, discarding the only per-child liveness signal a backgrounded child emits. A usage-free progress frame now refreshes the clock, which changes publish FREQUENCY on that shared path. `startedAt` is untouched everywhere. It is the spawn stamp two roster sorts, `compareWorktreeAgentRows`, cap eviction, and the equality/shed digest all depend on, so this adds a second field rather than moving that one. The time column is untouched too: it is documented bimodal (finish-time for a done row, start-time for an active one), so "14m" on a working child is a correct elapsed duration. Absent means the host never reported it, never "never active" — deliberately NOT normalized to 0 the way `startedAt` is, which would render as decades of silence. The reader keeps the parent `updatedAt` borrow as the documented old-host fallback. The shed-roster digest deliberately excludes the new field: it moves on every child tool event, so folding it into an IDENTITY digest would make a shed roster almost never match its cached twin, and an unrestored roster blanks live child rows and unblocks hibernation. Moves the tracked-row merge and the progress-frame fold next to the row type they belong to, which also keeps the tracker inside its line budget.
