+## Background
+
+`yoi panel` currently feels delayed when opening the panel, attaching from the panel to a Pod, and returning from an attached Pod back to the panel.
+
+The delay is not waiting for an LLM response. It is mostly waiting for synchronous local/runtime work before the next screen is drawn:
+
+- initial panel load waits for a full panel snapshot;
+- Ticket-enabled panel load can ensure/observe the workspace Orchestrator before first draw;
+- opening a Pod waits for socket connect or restore/spawn before visible transition;
+- returning from a nested Pod waits for a synchronous panel reload before showing the panel again.
+
+The panel already has a background `PendingReload` mechanism while it is visible, but the open/attach/return transition paths still block on reload/connect work before changing the visible screen.
+
+## Goal
+
+Make workspace panel transitions feel immediate by showing the next relevant screen/state first and moving snapshot reload / Pod connection / Orchestrator observation work into background or explicit progress states where practical.
+
+## Problem points
+
+Current important paths:
+
+```text
+yoi panel
+→ MultiPodApp::load(...)
+→ load_multi_pod_snapshot(..., OrchestratorLifecycleMode::Ensure)
+→ first draw only after snapshot/ensure completes
+```
+
+```text
+panel Enter on Pod
+→ prepare_open()
+→ run_pod_name_nested(...)
+→ try_connect_live_pod / restore/spawn
+→ single-Pod screen only after connect/restore is ready
+```
+
+```text
+return from attached Pod
+→ app.finish_open(...)
+→ app.reload_or_notice().await
+→ panel draw only after reload completes
+```
+
+## Requirements
+
+- Returning from an attached Pod should redraw the previous panel immediately, with a clear refreshing notice, then perform snapshot reload in the background.
+- Avoid awaiting `app.reload_or_notice().await` on the attach-return path before the panel is visible.
+- Opening/attaching a Pod should visibly transition to an attaching/restoring progress state before waiting on socket connect or restore/spawn.
+- Initial `yoi panel` open should avoid blocking first draw on non-essential refresh/ensure work where practical.
+  - A minimal/loading panel or last/current partial snapshot is acceptable.
+  - Orchestrator ensure can be surfaced as background progress/diagnostic if it cannot be completed before first draw cheaply.
+- Preserve correctness: background reload must still update Pod state, Ticket rows, Orchestrator state, and diagnostics when it completes.
+- Preserve no-Ticket Pod-centric behavior.
+- Do not lose key input during transition/progress states.
+- Do not introduce duplicate overlapping reload tasks; reuse/extend `PendingReload` or similar guard.
+- Do not change Ticket workflow semantics or Pod restore/spawn authority.
+
+## Non-goals
+
+- Changing Ticket workflow state.
+- Changing Orchestrator scheduling semantics.
+- Rewriting the whole TUI runtime loop.
+- Replacing the single-Pod TUI.
+- Cosmetic layout tuning unrelated to transition latency.
+
+## Acceptance criteria
+
+- Returning from a nested Pod displays the panel before panel snapshot reload completes.
+- Panel shows a concise `refreshing` / `attaching` / `restoring` style notice during background work.
+- Background reload completion updates the panel without dropping selection/composer text unnecessarily.
+- Attach/open path gives visible feedback before slow socket connect/restore work.
+- Tests cover the non-blocking return/reload behavior where practical.
+- Existing validation for panel, Pod-centric mode, and Ticket-enabled mode continues to pass.

+
+## Plan
+
+Created from investigation of perceived delays when opening `yoi panel`, attaching to a Pod, and returning from an attached Pod.
+
+Root cause recorded:
+- the panel waits for full snapshot/Orchestrator work before first draw;
+- attach waits for socket connect or restore/spawn before a visible transition;
+- return from nested Pod awaits `app.reload_or_notice().await` before showing the panel again.
+
+Desired direction:
+- show the panel/progress state first;
+- move reload/connect/ensure work into background or explicit progress states where practical;
+- especially make return-from-attach redraw the previous panel immediately and refresh in the background.
