Comment:
**Misleading test comment about `loadHistory`**

The comment says "Only `/reset` loads history", but in production `setSession` (called by `/new`) internally calls `loadHistory()` at the end of its implementation (`tui-session-actions.ts:367`). The assertion is correct for the mocked harness only — the comment should clarify that:

```suggestion
    expect(loadHistory).toHaveBeenCalledTimes(1); // /new loads history via setSession (mocked here); /reset loads it directly
```

How can I resolve this? If you propose a fix, please make it concise.

Comment:
**Truncated UUID reduces session key entropy**

`.slice(0, 8)` keeps only the first segment of the UUID, giving 32 bits of entropy for the generated session key. The whole point of this change is to guarantee per-client isolation — a key collision between two clients would silently re-share a session and reintroduce the broadcast bug. Consider dropping the `.slice(0, 8)` and using the full UUID to eliminate the risk with no added cost.

Comment:
**Log message reads potentially-stale `currentSessionKey`**

`chatLog.addSystem` is called with `state.currentSessionKey` after `await setSession(uniqueKey)`. Whether `state.currentSessionKey` has been updated to `uniqueKey` by this point depends entirely on the `setSession` implementation. The test harness mock never updates `state`, so in tests the message will always show the old key (`"agent:main:main"`), masking any regression here.

Using the locally-known `uniqueKey` is unambiguous and consistent regardless of when/whether `setSession` mutates the state:

```suggestion
          chatLog.addSystem(`new session: ${uniqueKey}`);
```

Comment:
**Stale token counts after `/new`**

The `/reset` handler explicitly zeroes out `state.sessionInfo.inputTokens`, `state.sessionInfo.outputTokens`, and `state.sessionInfo.totalTokens`, then calls `tui.requestRender()` before awaiting the network call (see the `// Clear token counts immediately to avoid stale display (#1523)` block). The `/new` handler has no equivalent cleanup, so the status bar will continue to display the old session's token counts until the first reply arrives in the newly-isolated session.

Consider adding the same token-clearing block at the top of the `"new"` case:
```
state.sessionInfo.inputTokens = null;
state.sessionInfo.outputTokens = null;
state.sessionInfo.totalTokens = null;
tui.requestRender();
```
