Summary

Messages typed or pasted into the TUI disappear silently — no response, no error, and the message is not visible in the conversation history afterwards. The user watches the message vanish from the screen while looking at it.

This is distinct from the existing input-swallowed-during-generation bug (#45326). This happens even when the agent is idle.

Steps to reproduce

1. Open TUI (openclaw tui)
2. Type or paste a message while agent is connected | idle
3. Press Enter
4. Message appears briefly then vanishes — not in history, no reply, no error

Expected behavior

Message should appear in history and agent should respond. If something fails, an error should be shown — not silent disappearance.

Impact

Combined with the exec approval popup flood and NO_REPLY issues from 2026.4.1, the TUI is completely unusable. User cannot type commands, cannot get responses, and cannot run exec. A full working day lost.

Environment
