"Page N" entries come from review stand-ins created after Approve saved only
the visible page's regions. New core/magazine_untitled.py classifies untitled
entries (continuation, article head, advert, picture page, contents, junk),
proposes merges into the previous article with confidence and evidence
(optional LLM check in the ambiguous band), and suggests titles
(deterministic, optional validated and cached LLM titles). Exposed through
derived GET /articles fields, GET /untitled, quality report, undoable
merge-into-previous / accept-title routes, POST /titles/suggest and
scripts/magazine_untitled.py (dry run by default, --apply backs up first).
Merges mark audio_stale; no audio is deleted; real titles are never
overwritten.
