npm run dev now runs scripts/dev-env.ts first, which creates .dev/site.env with
a known dev password and a random session secret, so a fresh clone serves a
working admin without anyone hand-building a hash. Adds .vscode launch
configurations and tasks for the dev server, one test file, and check-site, and
brings scripts/ under typecheck, which it had been missing.
verify reports integrity problems and repair rebuilds derivatives from the
Originals, which is what makes the file layout trustworthy without a database.
The image runs TypeScript on Node 24 with no build step, writes only under
MENU_ROOT, and the provision script writes the untracked site.env using the
image's own hasher so the server needs no Node.
