+## Background
+
+The `--multi` dashboard frequently shows `[live unknown]` for reachable Pods. Current code probes each runtime-registry socket with a very short `LIVE_STATUS_PROBE_TIMEOUT` of 25ms in `crates/tui/src/pod_list.rs`. A live row becomes `status = None` when the socket connects but no `Event::Snapshot` / `Event::Status` is read before that deadline.
+
+That label is misleading: the Pod is reachable, but status probing timed out or did not receive a status event quickly enough. Raising the timeout alone risks making dashboard reload latency scale linearly with the number of live Pods, because status probes are currently performed sequentially.
+
+## Requirements
+
+- Increase the live status probe timeout to a more realistic value, likely in the 150ms–250ms range.
+- Run live status probes concurrently so reload latency does not become the sum of all per-Pod timeouts.
+- Keep reachable Pods with missing status as live/attachable; do not treat status timeout as unreachable.
+- Keep restoreability separate from live attachability; this ticket must not make runtime-only Pods restorable.
+- Replace or soften the `live unknown` label in `--multi` so it communicates reachable-live-with-unreported-status rather than broken state. Candidate labels: `live`, `live probing`, or similar.
+- Keep the implementation in shared `PodList` / live probe code where possible; avoid duplicating dashboard-specific discovery logic.
+- Preserve existing behavior for explicitly reported `Idle`, `Running`, and `Paused` statuses.
+
+## Non-goals
+
+- Do not redesign Pod notification or run completion delivery.
+- Do not persist last-known status in pod-store.
+- Do not change `AttachOrRestorePod` or restore semantics.
+- Do not make unreachable registry allocations appear attachable.
+
+## Acceptance criteria
+
+- Multiple live Pod status probes wait concurrently, not strictly one after another.
+- The per-Pod timeout is long enough to significantly reduce false `status = None` cases compared to 25ms.
+- A reachable Pod whose status probe times out remains displayed as live and openable/attachable.
+- The multi-Pod row label for `status = None` is less misleading than `live unknown`.
+- Tests cover concurrent probing behavior, timeout/none-status handling, and label rendering.
+- `cargo test -p tui pod_list`, `cargo test -p tui multi_pod`, `cargo test -p tui`, `cargo fmt --check`, and `./tickets.sh doctor` pass.

+## Plan
+
+## Preflight
+
+Classification: implementation-ready.
+
+The issue is localized to TUI live status probing and dashboard labeling. The product decision is settled: reachable Pods with missing status remain live/attachable, while status probe timeout should be less frequent and less alarming. No restore semantics or Pod runtime protocol changes are required.
+
+Current code map:
+- `crates/tui/src/pod_list.rs`: `LIVE_STATUS_PROBE_TIMEOUT`, `load_live_pods`, `probe_live_status`, `LivePodInfo`, `PodList` merge/sort tests.
+- `crates/tui/src/multi_pod.rs`: row label rendering for live status, currently `live unknown` when `LivePodInfo.status` is `None`.
+
+Critical risks:
+- Do not make reload latency scale as N * timeout.
+- Do not treat `status = None` as unreachable.
+- Do not change restoreability/attachability semantics.
+- Avoid duplicating discovery logic outside shared `PodList`.
