Identifies who will read a piece of content, picks an appropriate number of representative readers (as few as cover everyone who must understand or act), reviews the draft through each reader's eyes, and aligns the content so every audience gets what it needs. USE FOR: issues, user stories, PR descriptions, release notes, announcements, ADRs, help articles, or reports where several audiences matter; "who will read this", "review this for the audience", "make this work for product owners and developers", "is this clear to a newcomer". DO NOT USE FOR: formatting the final text (use fusion-agent-content), testing a running app with personas (use fusion-simulated-user-eval), or publishing without confirmation.
