 ## [Unreleased]
 ### Added
+- **Untitled magazine entries ("Page 33") are explained, merged on request and given readable titles** (`core/magazine_untitled.py`, `scripts/magazine_untitled.py`). Root cause: the review screen creates a `Page N` stand-in for any page no article covers, and *Approve* without a toggled box saved only the visible page's regions, which cut multi-page features down to one page. On *c't KI Wissen 2026* this left 59 stand-ins, most of them continuation pages. A continuation detector scores each untitled entry against the article before it (lower-case/mid-sentence start, hyphenated break, the narration fusion rule, open ending, adjacent page, column width; a signed-off previous article or the page's own headline counts against). An optional local-LLM check runs only for ambiguous scores. Each proposal comes with a confidence and the evidence. Records whose title repeats the headline of the article they continue are proposed as well. Titles: a deterministic fallback (*Anzeige*, *Bildseite*, *Inhalt*, *Impressum*, *Editorial*, *Textfragment*, the page headline, or the first sentence cut to 8 words), plus optional validated and cached LLM titles in the magazine's language (`magazine_llm_titles`, `--no-llm`). Nothing changes silently. `GET /articles` gains derived `display_title`, `title_source`, `suggested_title`, `page_label`, `untitled_kind`, `merge_suggestion` and `audio_stale`, and `GET /untitled` plus `quality/report → untitled_articles` list everything. Changes happen only through the undoable `POST /articles/{id}/merge-into-previous` and `POST /articles/{id}/accept-title` (never over a real title), `POST /titles/suggest` (suggestion cache only), and the CLI's `--apply` (backup first). A merge keeps reading order, marks the article `audio_stale` (a fresh render clears it) and deletes no audio. See architecture/magazine-ingestion.md, "Untitled entries".
 - **Distinct, deterministic face profile per character** (`core/face_profile.py`). The cast of one book looked like one family because most sheets name no facial feature and the image model then draws its default face. Each character now gets a compact `face:` clause (face shape, jaw, nose, eyes, brows, mouth, cheekbones, skin, hair colour and style, facial hair, age signs, a mark) in the Subject of every character prompt: traits the sheet states (German or English) are kept, the rest comes from species/age/gender/culture-filtered option pools, chosen so that the characters of a book are spread apart (greedy max-distance in creation order; adding characters never changes an existing profile; relatives named in `relationships` share a few traits). Owner override: a `visual_face` text on the sheet. On the real books 02/03 the mean pairwise face-descriptor distance goes from 0.09/0.04 to 0.91 (44/68 characters had no face trait at all). See `architecture/character-visual-identity.md`.
 - **Dry run for faces:** `POST /api/character-face-preview {book}` lists every character's face profile (what came from the sheet, what was chosen) with a similarity matrix and before/after score; `POST /api/character-prompt-preview` also returns `face_clause`. Nothing is generated or saved.
 - **Character info is translated to English before image prompts are built** (`core/prompt_translation.py`, `_english_prompt_inputs`). Free-text sheet fields (species, appearance, clothing, age, props, story-moment quote) and the book setting are translated in one batched, low-temperature call through the app's existing LLM, validated per field (non-empty, no error echo, length, names preserved, not still German), and cached in the new `prompt_translation_cache` table keyed by source hash, language, model and prompt version. Records and the displayed German text never change; species/age/dwarf/period checks now run on English. If the LLM is down or output is rejected the original text is used, a warning is logged, `prompt_translation.used_untranslated_text` is reported and generation continues. `PROMPT_TRANSLATION=off` disables it. New read-only dry run `POST /api/character-prompt-preview`. See architecture/character-visual-identity.md.

+### Untitled entries ("Page 33") and continuation pages
+
+**Purpose:** clean up contents/driving-mode entries that have no real title (`Page 33`, `Page 69` …). Most of them are continuation pages of the article before them that ended up as entries of their own. The others are advert pages, picture pages, or short text fragments.
+**Why they exist:** the review screen creates such an entry when you open a page no article covers. A page loses its article when an article is approved on another page without any box being toggled: only the visible page's boxes were saved, so the other pages fell out of the article.
+**What you get (nothing changes on its own):**
+- Every entry now carries a **display title**. Real titles are shown unchanged. Placeholder titles show a suggestion instead: *Anzeige*, *Bildseite*, *Inhalt*, *Impressum*, *Editorial*, *Textfragment*, the page's own headline, or its first sentence (at most 8 words). The page number comes separately (`page_label`, e.g. "Seite 33") so the index can show it in smaller text.
+- A **merge proposal** when an entry looks like the continuation of the previous article. Each proposal has a confidence (*high* ≥ 0.75, *medium* ≥ 0.5) and the evidence, for example "starts lower-case / mid-sentence", "previous text ends in a hyphenated word break", "adjacent page" or "previous article is signed off".
+- `GET /api/magazine/{id}/untitled` lists all of them with counts. The quality report (`GET …/quality/report`) carries the same list as `untitled_articles`.
+**Steps:**
+1. Look at the proposals (`GET …/untitled`, or the dry run below).
+2. Merge one: `POST /api/magazine/{id}/articles/{article}/merge-into-previous` with `{"into": "<proposed id>"}`. It can be undone with **Undo**.
+3. Accept a title: `POST …/articles/{article}/accept-title` (optionally `{"title": "…"}`). An entry that already has a real title is refused, so titles you typed are never overwritten.
+4. Optional, better titles from the local LLM: `POST …/titles/suggest` (background job). It only fills the suggestion cache (`title_suggestions.json`). Switch it off with the setting `magazine_llm_titles: false`.
+5. Whole magazine from the command line: `python3 scripts/magazine_untitled.py <doc-id>` is a dry run that changes nothing. Add `--apply` to write: a backup `articles.backup-untitled-<time>.json` comes first, then every proposal ≥ `--min-confidence` (default 0.75) is merged in page order and suggested titles go into placeholder titles. `--no-llm` keeps it fully deterministic.
+**Expected result:** continuation pages become part of their article (pages and regions in reading order), and the index shows readable names with the page number beside them.
+**After a merge:** the merged article is marked `audio_stale` ("render the audio again"). Its old MP3 still plays the shorter text until you render it again, and a fresh render clears the mark. The merged-away entry's MP3 and timings stay on disk and are not deleted. An approved article stays approved only if both parts were approved.
+**Errors:** "The proposal changed" (409) means the articles changed since the list was loaded, so reload and look again. "No merge is proposed" (409) means the entry is not a continuation by the current rules. If the LLM is unreachable, the run says so once and uses the deterministic titles.
+**Mobile / accessibility:** data only (API fields). The index shows `display_title` with `page_label` in smaller text, and the full title stays available to screen readers.
+**Offline / privacy:** the heuristics run locally. LLM titles use only the LLM configured in Settings and send it at most 1,500 characters of the entry's text.

+## Untitled entries: continuation pages and suggested titles (2026-10-03)
+
+### Why "Page N" entries exist
+
+Ingestion itself never writes a `Page N` title: `group_articles` titles an article from a
+contents entry or a headline, and `auto_link_pages` names new pieces after their headline. The
+placeholder comes from the review UI. `magReviewPage(n)` (static/js/magazine.js) creates a
+stand-in article titled `Page n` (`POST /articles`) whenever the reviewer opens a page that no
+article covers, and *Approve* advances to the next page that way. A page becomes uncovered when an
+article loses it: *Approve* PATCHes `blocks` with the ticked boxes, and when nothing was toggled
+`selectedBlockIds()` falls back to the check boxes rendered for the visible page only, so the
+article's `pages` shrink to that page (`PATCH` recomputes pages from blocks). On `c't KI Wissen
+2026` this turned 16 multi-page features into one-page records (e.g. *Per KI von der Idee zum
+Programm* went from pages 68–73 to 68) and produced 59 stand-ins, 45 of whose regions had belonged
+to a real article in the 2026-09-28 relink backup. Each approved stand-in was then rendered as
+its own MP3, which is why the driving-mode index lists `Page 69`, `Page 70` and so on. A stand-in on a
+page with only pictures or an advert has no narratable text (`Page 33`, no audio). One that holds
+only an image credit gives a 2-second MP3 (`Page 34`).
+
+### Detection (`core/magazine_untitled.py`, pure, no I/O)
+
+An entry is *untitled* when its title is empty or matches `Page \d+`/`Seite \d+`/`Untitled`.
+Each untitled entry is classified into exactly one `kind`:
+
+| kind | rule |
+|---|---|
+| `empty` | no region with text; `image_only` when the page has pictures |
+| `advert` | `page_is_advertisement`, or only `ad` regions |
+| `contents` / `imprint` / `editorial` | a leading heading reads *Inhalt*, *Impressum*, *Editorial* (or English equivalents) |
+| `junk` | under 60 letters of narratable text, or only credits/page furniture (`looks_like_page_junk`) |
+| `continuation` | merge suggestion with confidence ≥ 0.5 (below) |
+| `article_head` | the first narratable region is a real headline (`looks_like_real_title`): a new article whose record lacks the title |
+| `untitled_article` | everything else |
+
+**Continuation (idea A).** The *previous entry* owns the closest narratable region before the
+entry's first region, in (page, reading order), at most one non-advert page between them.
+The score starts at 0.1 and is clamped to 0..1:
+
+| signal | weight |
+|---|---|
+| entry text starts lower-case (`ihn. An vielen Ecken …`) | +0.45 |
+| previous text ends in a hyphenated word break (`Trans-`) | +0.40 |
+| the narration fusion rule `paragraph_continues` accepts the seam | +0.30 |
+| previous text ends without terminal punctuation | +0.30 |
+| adjacent page (or only advert pages between) | +0.15 |
+| similar body column width (±20 %) | +0.05 |
+| previous entry is signed off (`(hag) ct`, `_ARTICLE_END_RE`) | −0.60 |
+| entry starts with its own headline | −0.50 |
+
+A suggestion is made at ≥ 0.5 (`medium`), and from 0.75 it is `high`. An optional LLM check (local model through the
+app's chat client, `{"continues": true|false}`, mocked in tests) is consulted only in the
+ambiguous band 0.35–0.75 and moves the score by ±0.2. Titled records whose title repeats the
+headline of the chain they continue (*Durchstarten, bis die KI-Blase platzt?* on page 53 after its
+own head on page 48) are proposed too (`duplicate_title`), because they are the same truncation
+seen from the other end.
+
+**Titles (idea B).** `deterministic_title` returns, in order: a type label for recognised kinds
+(*Anzeige*, *Bildseite*, *Inhalt*, *Impressum*, *Editorial*, *Leere Seite*; English labels for
+English issues), else the first headline-like region (≤ 90 characters, real title), else the
+first full sentence (a leading mid-sentence fragment is skipped) cut to 8 words with `…`. The page
+number is **not** part of the title. The API returns it separately (`page_label`) so the index can
+show it in smaller text. `llm_title` optionally asks the local model for a ≤ 8-word title in the
+magazine's language with a strict *title only* prompt. The answer is validated (one line, 2–8 words,
+≤ 70 characters, no prefixes or chatter, at least one content word from the text) and cached in
+`<doc>/title_suggestions.json`, keyed by article id and a hash of its text plus the prompt version. On any failure
+it falls back to the deterministic title. Setting `magazine_llm_titles: false` or `--no-llm`
+switches the LLM off.
+
+### Nothing changes silently
+
+* `GET /articles` adds derived, unsaved fields: `display_title`, `title_source`
+  (`title` | `suggested` | `placeholder`), `suggested_title`, `suggested_title_source`
+  (`heading` | `sentence` | `type` | `llm`), `untitled_kind`, `first_page`, `page_label`,
+  `merge_suggestion` (`{into, into_title, confidence, level, evidence[]}`) and `audio_stale`.
+* `GET /untitled` returns the full report (counts per kind, suggestions, evidence).
+  `GET /quality/report` attaches the same report live as `untitled_articles`.
+* `POST /articles/{id}/merge-into-previous` (body `{into}` must match the current suggestion
+  target, otherwise 409) merges one entry, and Undo can reverse it.
+  `POST /articles/{id}/accept-title` writes the suggested (or given) title. It refuses with 409 when the
+  current title is not a placeholder. Titles that someone set are never overwritten.
+* `POST /titles/suggest` runs the LLM title pass as a background job (cache only, titles unchanged).
+* `scripts/magazine_untitled.py <doc-id|dir>` prints the dry run (default). `--apply` first
+  writes `articles.backup-untitled-<ts>.json`, then merges suggestions ≥ `--min-confidence`
+  (default 0.75) in page order and writes suggested titles into placeholder titles only.
+
+**Merging** (`merge_entries`): the earlier entry keeps its id; the later entry's regions are
+inserted in (page, reading order). Pages, pictures, `continued_to`/`continued_from` and
+`merged_from` are united, and the later record is removed. The title is kept unless it is a placeholder and the later
+entry has a real one. The status stays `approved` only when both were approved. The merged record
+gets `audio_stale: true` with `audio_stale_reason`. Audio and timing files are **not** deleted
+(the removed entry's MP3 stays on disk, orphaned). A successful render
+(`_synthesize_article_audio_sync`) clears the flag.
+
+### Known limitations
+
+* The review-UI bug that creates the stand-ins (`selectedBlockIds` fallback) is in
+  `static/js/magazine.js` and is not fixed here. Until it is, new stand-ins can appear.
+* Reading order across a page that holds two articles relies on the existing per-page order. A
+  wrong page order gives a wrong *previous entry*.
