"""AutoCode product-study: create, source-link and gate a product blueprint.
Standard library only (Python 3.8+). Works on <root>/<slug>/blueprint.md next
to the sources.json that fetch_public.py produced.
Usage:
  blueprint.py init <slug> --product NAME [--site URL] [--goal TEXT] [--root DIR] [--force]
      Copy references/blueprint-template.md into place with the header filled in,
      then append the Sources section from sources.json.
  blueprint.py sources <slug> [--root DIR]
      Regenerate the "## Sources" section from sources.json (run after fetching more).
  blueprint.py check <slug> [--root DIR]
      Gate: every claim carries a source and a confidence tag, sources exist, no
      placeholders, no copied sentences, no asset links or long code blocks, MVP
      cut within size. Exit 0 = pass, 1 = fail. Prints one line per check.
  blueprint.py mvp <slug> [--root DIR]
      Extract the MVP cut (sections 9 and 10 + header) into mvp.md: the hand-off
      to the build phase. Refuses while section 9 still has TODO.
