Summary

The TUI crashes with "Rendered line exceeds terminal width" when displaying chat messages containing audio attachments with long UUID-based filenames.

Environment

• OpenClaw Version: 2026.1.29 (a5b4d22)
• Platform: Linux Ubuntu (Docker container)
• Terminal Width: 220+ characters (tested multiple widths)
• Feature: Audio transcription enabled (Whisper CLI)

Steps to Reproduce

1. Enable audio transcription in config:

   "tools": {
     "media": {
       "audio": {
         "enabled": true,
         "models": [{"type": "cli", "command": "whisper", "args": ["--model", "base", "--output_format", "txt", "{{Media}}"]}]
       }
     }
   }

2. Send voice messages via Telegram (generates long paths like /home/user/.openclaw/media/inbound/file_6---1c8d3cc5-a4bb-423a-8c7b-6327d7783bf7.ogg)
3. Try to open TUI with openclaw tui --password <password>
4. TUI crashes immediately during render

Expected Behavior

• TUI should truncate or wrap long file paths
• Audio messages should display cleanly in TUI

Actual Behavior

Error: Rendered line 366 exceeds terminal width (244 > 220)
TUI.doRender crashes

The crash log shows the problematic path:

/home/moltbot/.openclaw/media/inbound/file_6---1c8d3cc5-a4bb-423a-8c7b-6327d7783bf7.ogg

Regression

• TUI worked perfectly before enabling audio transcription
• Issue started immediately after first voice message
• Web UI works fine with same content

Workaround

• Use Web UI instead of TUI
• Or start new session without audio history

Suggested Fix

Add proper path truncation/ellipsis for long file paths in TUI audio message display.
