Bug

When using openclaw tui, internal system messages like pre-compaction memory flush prompts are rendered as regular chat messages visible to the user.

Expected: System messages (compaction flush, heartbeat prompts, etc.) should be hidden from the TUI display.

Actual: Messages like this appear in the TUI chat:

Pre-compaction memory flush. Store durable memories now (use memory/2026-03-02.md; create memory/ if needed). IMPORTANT: If the file already exists, APPEND new content only and do not overwrite existing entries. If nothing to store, reply with NO_REPLY.

Environment:

• OpenClaw 2026.3.1
• macOS 26.3 (arm64)
• Compaction mode: safeguard
