What issue are you seeing?

In the Web UI sidebar, clicking on an archived session does not open it. The session appears in the "Archived" collapsible section, but clicking it has no effect — the chat area remains unchanged and the session is not loaded.

Expected behavior

The archived session should open in the main chat area, loading its conversation history.

Actual behavior

Nothing happens. The session is not selected and the chat area does not update.

Root cause (from code inspection)

The bug is in web/src/App.tsx. The useEffect that validates selectedSessionId only checks the sessions array (active/non-archived sessions):

const sessionExists = sessions.some(
  (s) => s.sessionId === selectedSessionId,
);
if (!sessionExists) {
  selectSession(""); // clears selection
}


Because archived sessions are stored separately in archivedSessions, this check incorrectly clears the selection immediately after the user clicks an archived session.

Additionally, currentSession only searches in sessions:



const currentSession = useMemo(
  () => sessions.find((session) => session.sessionId === selectedSessionId),
  [sessions, selectedSessionId],
);
Suggested fix
Update sessionExists to also check archivedSessions:


const sessionExists =
  sessions.some((s) => s.sessionId === selectedSessionId) ||
  archivedSessions.some((s) => s.sessionId === selectedSessionId);
Update currentSession to search both arrays:


const currentSession = useMemo(
  () =>
    sessions.find((session) => session.sessionId === selectedSessionId) ||
    archivedSessions.find((session) => session.sessionId === selectedSessionId),
  [sessions, archivedSessions, selectedSessionId],
);


3. Add `archivedSessions` to the `useEffect` dependency array.

### What steps can reproduce the bug?

## Steps to reproduce
1. Start Kimi Web UI (`kimi web` or `/web` in CLI).
2. Have at least one archived session (or archive an existing one via right-click → Archive).
3. Expand the "Archived" section in the left sidebar.
4. Click on any archived session.

### What is the expected behavior?

_No response_

### Additional information

_No response_

Start in web/src/App.tsx and inspect the selected-session validation and currentSession lookup, then run the Kimi Web UI with kimi web or /web and reproduce the archived-session click. Done means an archived session remains selected and its conversation history loads in the chat area after clicking it.
