/**
 * TITAN — v6.1.0-alpha.57 live notebook fill + classifier widening
 *
 * Tony: "This part with the lined paper is not live and I do not
 * see it writing in it yet. … It's supposed to look like the AI
 * is writing in a notebook. Then once a page gets full it turns
 * the page."
 *
 * Investigation showed two separate problems on the AI writeup
 * mission:
 *
 *   1. `room.artifact.content` was empty for the entire mission
 *      lifecycle. `missionRoom.ts` exports `updateArtifact()` but
 *      no caller in the codebase ever invoked it. The
 *      DocumentPaper component on the canvas was correctly reading
 *      `room.artifact.content` but there was nothing to render.
 *
 *   2. The goal "Do a complete and detailed writeup on the
 *      advances on AI and AI Agents" classified as `analysis`
 *      because the title classifier's `write` regex only matched
 *      "write [adj] writeup" — bare "writeup" without a leading
 *      "write" / "draft" / "compose" verb fell through.
 *
 * alpha.57:
 *
 *   - Added a noun-only classifier pass that catches
 *     `writeup|essay|article|whitepaper|press release|newsletter|
 *     op-ed|briefing` even without a verb prefix.
 *   - missionLifecycle's `agent_done` handler now reads the
 *     specialist's file artifact, strips HTML to plain text, and
 *     streams it into the mission's artifact buffer in 80ms
 *     chunks (~4s total) so the notebook fills in front of the
 *     user.
 *
 * Page-turn animation is a UI follow-up — these tests pin the
 * backend pieces.
