Problem

Internal system messages can sometimes appear in the conversation stream looking like a normal user message. Example seen in the Control UI / TUI:

Pre-compaction memory flush. Store durable memories now ...

From the user side, this reads as if they sent a strange message, or as if the assistant is emitting raw internal plumbing into the normal chat.

Suggested behavior

Keep showing these messages if they are useful for transparency, but render them in a clearly distinct visual treatment so they are obviously:

• not from the user
• not from the assistant
• from the system/runtime itself

For example:

• a separate colored block
• a "System" badge/header
• muted/diagnostic styling
• optionally collapsible

Why this would help

Right now the main UX problem is not that the message exists, but that it is easy to confuse with normal chat traffic. A distinct block would preserve transparency without making the user feel like they accidentally sent an internal prompt.

Concrete example

A user saw a pre-compaction memory flush message in chat and reasonably thought it looked like something they had typed and sent. The request was specifically:

• keep messages like that visible
• but show them in a different colored block so they are clearly system-originated

Thanks — seems like a small UI distinction that would reduce confusion a lot.
