What

An attachment is an extra piece of information added to the conversation alongside messages. A new attachment type, advisor_stripped, is added once per request when the strip mode is strip_and_mark. The mode depends on the current state rather than on a setting, and relayThinkingStripOwed picks strip_and_mark for the main conversation. The attachment is on the list of hidden attachments and displays nothing.

Why

You will not see this marker on screen. It leaves a note in the conversation record that relayed thinking was removed.
