- If a dialog appears (e.g., "Help Us Improve Jan" or "New Version/Update"), dismiss it before proceeding.
- The **Add Assistant** dialog has its own vertical scrollbar; if controls are not visible, click inside the dialog to focus it, then scroll or drag the dialog’s scrollbar handle.

## User Instruction

Verify that the default predefined parameters for a new assistant are correct, keys are lower snake_case, and that saving/reopening preserves the values.

### Steps

1. Open **Assistants** from the bottom-left menu.
2. Click **Create Assistant** to open the **Add Assistant** dialog.
3. In **Name**, type: `Param Tester`
4. In **Description**, type: `For parameter editing verification.`
5. In **Instructions**, type: `Test assistant for changing predefined parameters.`
6. In **Predefined Parameters**, click each chip so it appears in the **Parameters** list (scroll within the dialog if needed):
   - Stream
   - Temperature
   - Frequency Penalty
   - Presence Penalty
   - Top P
   - Top K
7. Verify the **default values** shown after toggling the chips match exactly:
   - Stream: **True** (Boolean)
   - Temperature: **0.7**
   - Frequency Penalty: **0.7**
   - Presence Penalty: **0.7**
   - Top P: **0.95**
   - Top K: **2**
8. Click **Save**.
9. In the Assistants list, locate **Param Tester** (scroll the list if necessary) and click its **Edit** (pencil) icon.
10. Verify the assistant’s **Name**, **Description**, **Instructions**, and all **Parameters** are present and unchanged (scroll within the dialog if needed).
11. Click **×** to close the dialog.

## Pass/Fail Output (strict)
- Respond in English only.
- Return ONLY one of the following JSON objects, with no extra text.

If all parameters are visible, default values match exactly, and the saved assistant reopens with the same values and texts, return:
  {"result": true}

Otherwise, return:
  {"result": false}

IMPORTANT:
- Your response must be ONLY the JSON above.
- Do NOT add any other text before or after the JSON.
