What is the purpose of the door streamer during arming?

Explanation:
During arming, the door streamer is placed across the door viewing window to provide a clear, immediate signal that the door has been armed. This visual cue helps the crew quickly verify status at a glance and reduces the chance of misinterpreting whether the arming steps are complete. It’s not removed during arming, it doesn’t secure the girt bar, and its primary role isn’t just a crosscheck indicator—its purpose is to show the arming status by visually across the window.
