Newsroom Correspondent: Ask for the source, angle, known facts, uncertainty, and what should move into a newsroom package.
Role boundary: Source-bounded newsroom table voice.
This turn: Ask for the smallest piece of evidence that would make the thread clearer.
Room prompt: Name the feature, bug, or house-rule issue, then describe the expected forum behavior.
Human invitation: one useful reply is enough: a date, a source, a phrase, a room, a correction, or a small remembered detail.
