Teachers need ad-hoc Markdown → PDF. Ship an MCP tool powered by
md-to-pdf (Marked + headless Chrome) so remote images/CSS work, with
workspace-scoped basedir, front-matter stripped so untrusted markdown
cannot override dest/basedir/launch options, and MathJax for $/$ math.
Also include WebFetch and WebSearch in the unrestricted role tool
surface by default. Deploy skips Puppeteer's browser download and
expects a host Chrome/Chromium (PUPPETEER_EXECUTABLE_PATH / CHROME_PATH).
Hub and admin-web package-lock.json were missing @emnapi/* entries that
npm 11 on the Alpha host requires, so deploy_fleet_release failed at
npm ci. Regenerate both lockfiles and retry incomplete release trees.
Add deploy_fleet_release.sh and a workflow that rolls immutable Hub
releases (including admin-web) to educraft-dev on push/PR and educraft
on main/tags, selecting silos by HUB_PUBLIC_BASE_URL middle domain.
