 ## [1.55.0] — 2026-09-29
 ### Fixed
 - Tests: the form-pair fixture used the retired prompt version `v3` as "current"; the phone-width case of the Characters sorting test is marked known-failing (sticky name column covers the rating stars, tracked in TODO.md).
 - **Character scene images.** The scene prompt now states the character's gender and the book's pre-industrial period as hard constraints and asks for the focal person's face, upper body and hands in the near foreground. A sheet whose image checker is unavailable is no longer saved over a previously validated image: generation stops with a clear error instead. The weapon-integrity wording ("one hilt and one blade") is only added for characters who actually carry a weapon (it was planted into every scene).
 - The character-generation status poll rides out a transient 502/503/504 (proxy or app restart) instead of reporting a false "lost job".
 - **Voice benchmark failures now say why.** Designed voices are benchmarked through the Voice Design engine; when that service is down the row showed a bare "-" and the raw "Max retries exceeded" text. The error now names the service and the container to start, the Factor and WPM columns show `ERR` beside the time column, and a batch stops after three identical "unreachable" failures instead of retrying every remaining voice.
 ### Added
 - `architecture/ocr-porting-prompt.md`: a self-contained brief for carrying this app's OCR lessons (benchmark first, per-page escalation, fallback ladder, distrusting engine output, figure bounds from the render, box fitting, clean-up rules, quality audit, review UI) into another project.
 - `scripts/bench_ocr.py`: engine-agnostic OCR benchmark that scores an engine's transcription of rendered pages against a native-text PDF's own text layer (word F1, sequence similarity, seconds per page). First results (tesseract, Unlimited-OCR, docling, PaddleOCR) in `architecture/evidence/ocr-bench-2026-09-29/`: transcription accuracy is equal within noise (F1 0.865-0.881), tesseract is 4-20x faster; DeepSeek-OCR and Qwen3-VL-30B were not run (no memory headroom).
 - **Find an issue online (magazines).** A search panel in the magazine library finds issues in the Internet Archive and in any OPDS catalogue you configure (Calibre-Web, Kavita, Komga), shows the source's licence, and imports the PDF straight into a new magazine project, then starts ingestion. SSRF-safe (downloads only from the provider's own host), size/time bounded, feeds with DTDs refused. See `architecture/magazine-sources.md`.
 - **Magazine contents list shows synthesis state.** Each article row says "Synthesised · m:ss" (the MP3's exact length) or "Not synthesised" (approved, no MP3 yet), and has an inline play/pause button that streams the MP3 without opening the article. Icon plus words, screen-reader labelled, works at phone width.
 - `scripts/compare_magazines.py`: read-only comparison of two magazine folders (words, boxes, reading order, articles, quality numbers) for re-import checks.
 ### Changed (compare_magazines.py)
 - A page either side marks as a full-page advertisement is now excluded from every difference statistic and the worst-pages list, reported separately instead (`pages_skipped_as_advertisement`). Being marked an ad is a one-time manual step a fresh re-import has usually not had yet, so without this a page the baseline skips entirely (near-empty) was compared against the same page fully OCR'd in the new import -- a difference in review state, not pipeline quality, that was skewing the whole-issue numbers.
 ### Changed
 - Spelling agent and acronym resolver call the language model with thinking off (about 4 s instead of about 27 s per call) and retry without the option if the server rejects it.
 - The spelling agent treats run-together words (`dasich`) as errors and may split them at a space when both halves are real words and the letters are unchanged.
 - **A fresh import now finishes fully worked, not just laid out.** Ingestion runs the whole-issue Auto-fix pass (find missed text, re-read suspicious OCR, fix provable misspellings, link continuation pages, audit box coverage) itself as its last step, under the same job the ingest progress bar already follows -- no separate "Auto-fix all pages" click needed first. An Auto-fix failure is reported as an ingest failure (with the reason) rather than a silent gap; the ingest's own result (pages, articles) is kept either way.
 ### Fixed
 - Vision OCR: a refusal sentence the engine hallucinates over an unreadable photo or screenshot ("The image is too blurry to recognize...") is no longer narrated as page text -- discarded when the same sentence repeats across 3+ regions, confirmed live on c't KI Wissen 2026 pages 82, 87 and 124 (29 and 122 hallucinated regions dropped on re-OCR).
 - A duplicate box (its text already held by a wider box) that only becomes a duplicate once a later step in the same run grows or merges a box was left unmarked, so its text was narrated twice -- the duplicate check now also runs after the per-page box-fitting loop (ingest) and after finding missed text (the whole-issue quality run), not only before either. Confirmed live on 20 real pages across two runs of the same issue.
 ### Added
 - **Paragraphs are fused across columns and pages for narration.** A paragraph that continues into the next column or onto a later page is now one block in the reader and the exported MP3, so a sentence is no longer cut in two at the seam. Words split at the seam are closed up (`jähr-` + `lich`); real compound hyphens are kept; headings, interview turns and finished paragraphs are never glued together. Highlighting still follows the region each sentence began in.
 - **Pronunciation & spelling panel (per article).** Acronyms are spoken from the article's language (decided once per article, with per-block override for quotations) using an extended built-in list, letter-by-letter spelling for `USB`/`HDMI`-style acronyms, and an editable per-article glossary. Unfamiliar acronyms are listed with their sentence, and the language model can decide expansion / letters / word from context.
 - **German and English spellchecker with fix-or-mark.** Unknown words are underlined in the review list and listed with suggestions per page and per article; click a suggestion (undoable), or *Keep* to add the word to the issue's dictionary. *Fix with language model* corrects only what passes strict guards (a dictionary suggestion, or a known word within two edits) and keeps names/terms; the whole-magazine quality check now runs the same pass and reports pages with words still marked.
 - **Clean up boxes now also fits text boxes to their text.** A side that cuts through letters grows (at most a letter or two, never into a neighbouring box) and empty margins are trimmed. Boxes you drew or resized by hand are never touched. It also runs automatically after **OCR again (this page)**; on page 61 of the measured issue it widened the left-column paragraphs ~10 pt to cover their text, cutting clipped edges from 7 to 0. A box never grows into a neighbouring box; when it gains whole lines, its text is re-read from the enlarged crop and replaced only by a longer reading that still starts with the old text.
 - **Inset pull quotes get a region of their own.** A display-coloured quote set into the text (detection wraps body text around it, so no box covered it) is found from the page image — a muted-colour blob of quote size on plain paper that no headline, figure or existing pull quote covers — and added as a *pull quote* region (never read aloud). Runs after **OCR again (this page)** and in **Clean up boxes**. On the measured 204-page issue it finds the two real quotes (pages 40 and 62) and one infographic (page 139, harmless and deletable).
 - **A paragraph that wraps around an inset pull quote is cut into a full-width part and a narrow part**, so its box no longer sits over the quote (as the right-hand column already did). The text lines are measured from the page image; the text is cut in proportion to line width at a space, within a word or two of the printed break, and the two pieces are read in order and rejoined for narration. A paragraph whose lines are all narrow just gets a narrower box. Runs after **OCR again (this page)** and in **Clean up boxes**; new pieces join the same articles.
 - **Review shows what is wrong with each page, on the page.** A *What is wrong on this page* panel (measured live from the page render, not from the last run) explains each problem in plain language with its own fix button, and marks it on the boxes: red dashed frame = text outside any box, orange edge = a box edge cutting through text, purple dashed = two boxes over the same text, yellow dotted = words that look mis-read, red wavy underline = unknown words. **Fix this page automatically** fits boxes, adds inset pull quotes, cuts paragraphs that wrap around them, finds missed text, re-reads suspicious words and (with a language model) fixes provable misspellings, with one Undo.
 - **The whole-magazine run now fixes as well as checks:** *Quality check / run* also fits boxes, finds inset pull quotes and cuts wrapped paragraphs on every page before the missed-text, re-read and spelling steps, and reports how many boxes it fixed.
 - **Text flow indicator.** Review draws a green arrow where an article's text carries on to the next box below or the next column, and chips where it continues on another page (*continues on page 111 ›*, *‹ from page 110*) plus *article starts / ends*; a *Show text flow* switch hides them. The reading text shows small markers (`↓`, `col ›`, `p.111 ›`) at the exact word where a paragraph crosses a box, column or page. Built from the same fusion the narration uses (`GET .../articles/{id}/flow`), so the arrows show what is read as one paragraph. On the measured issue: 97 column, 29 page and 21 below continuations.
 - **The whole-magazine button is now named *Auto-fix all pages*** (it fixes boxes, adds pull quotes, finds missed text, re-reads words and fixes provable misspellings on every page) and keeps a layout backup first.
 - **Continuation pages are linked into their articles automatically.** Detection often found an article's headline page and left the pages that follow as one-page stand-ins ("Page 61") that had to be approved one by one (79 of 132 articles on the measured issue). Text no article owns is now attached to the article running from the page before, unless that article already ended (a signed end such as `(hag)`), it is more than two pages back, or a headline with a byline/deck opens a new article there. Text you already approved (as part of a stand-in page) stays approved when it is merged; an approved article that gains text nobody approved goes back to *detected*, so nothing unreviewed is ever narrated. Stand-ins whose text moved are removed. Runs at import, in **Auto-fix all pages**, and on its own (`POST .../articles/auto-link`, undoable).
 - **Link an article to a page by hand:** *Link to page N — Article continues there / starts there* in the review panel picks the text that belongs (the paragraph that carries the sentence on, up to the next headline) and adds it ticked; undoable.
 - **Flow arrows follow the reading order:** a green arrow for every jump to another column and for a sentence running across boxes (dashed when a new paragraph starts, solid when a sentence continues), chips for page jumps.
 - **Much less noise:** the *Auto-fix all pages* report now lists what was fixed and only the pages that need a decision about their boxes (with a *Start with page N* button and compact page pills); pages with only words to check are collapsed and optional. The per-box "words look mis-read" marks are gone (spelling keeps its red wavy underline). The spellchecker knows ~130 company/product names, treats a word printed twice anywhere in the issue as vocabulary (missing-umlaut words such as `fur` stay flagged) and treats two unknown capitalised words in a row as a person's name: 871 → 625 findings on the measured issue.
 - **"Article ends" is only claimed when it is true.** An article counts as ended when it is signed off (`(rah) et`, `(hag)` — OCR noise after the code is tolerated) or when the next region, on the same page or at the top of the next, is a headline, deck or byline. Otherwise the last box shows a clickable *no end marker — link page N ›* chip that adds the next page's text in one click.
 - **Photos and graphics that no box covers get a figure region automatically** (a dense unboxed blob of real size; thin, line-structured ink is text and is left alone). New figures join the article with the most text on their page.
 - **Text that is not narratable page furniture stays out of linked articles:** running heads that recur on 3+ pages, lists of page numbers and reference/source lists are no longer pulled in when continuation pages are linked. An article made only of text you already approved becomes approved.
 - The per-page fix and the whole-issue run keep `quality_report.json` in step, so the thumbnail badges and the list of pages needing a decision match the layout as it is now. Running heads and adverts are no longer audited for clipped edges or overlaps.
 - **Articles nobody has reviewed are blue.** In the article list an unapproved, unrejected article has a blue background and edge and a *not reviewed* pill (approved keeps its green edge), so what still needs a person stands out.
 - **Overlapping boxes are fixed automatically.** Where a lower-ranked box runs over a higher-ranked one (headline > deck/byline > body > caption/sidebar/pull quote), the lower one is cut back to the largest part that no longer overlaps, unless that would leave under 40% of it (then both stay for a human). Hand-placed boxes and boxes of equal rank are never touched.
 - **Fewer false alarms and better fits:** a strip of solid ink beside a headline (a photo or filled panel behind it) is no longer counted as letters cut off; headline and deck boxes may grow up to 70 px sideways (body boxes 16 px); an inset pull-quote box that repeats text a box already holds becomes a duplicate.
 - **Lines and frames are not missed text.** Beyond dotted leaders and thin rules, the audit now tells letters from lines by shape: text is many small separate marks, whereas a screenshot or chart frame, a vertical rule, a chart axis or a signature is a few large connected shapes (long and thin, or big and hollow). Only such shapes are ignored; a paragraph of text inside a frame, and a solid photo, are still found. Unboxed areas on the measured issue fell from 105 to 27.
 - **Rules and dotted leaders are not missed text.** The dots between a table-of-contents entry and its page number (and thin printed rules) are ink but no letters; the audit now ignores ink that is only a few pixel rows tall.
 - **Stacked boxes of a column now meet at the gap between two lines** (*seam mending*). Detection often cuts a column into slices that overlap or leave a line in the seam, so that line was in neither box and both reported a clipped edge. The shared boundary moves to the nearest blank gap (below the line for a paragraph that is still running, above it after a finished one, in the middle of an overlap); a line that had fallen into the seam is read on its own and attached to the box that now owns it, and the box takes the column's width. Page 32 of the measured issue: clipped edges 2 → 0 and the lost line "Entwicklungen auseinander. „KI ist bei uns in allen" is back in the text. 57 seams were mended across the issue.
 - **"Edge cuts text" needs the box's own lines.** Ink beside a left/right edge only counts as cut-off letters when it sits on the rows where the box itself has text and is intermittent (letters and gaps); a solid vertical line (a screenshot frame, a chart border, a photo edge) or ink between the box's lines does not, and a thin horizontal rule above or below is not a cut line. On the measured issue clipped edges fell from 82 to 48 and pages needing a decision from 53 to 42.
 - **Unboxed ink in or beside a picture, chart or advert is no longer reported as missed text** (labels of a chart, text set into a photo, an advert's own wording).
 - **Undo and Redo buttons in the sticky review bar**, at the left end of its second row (placed by measuring the bar, so they stay there at any window width), also on Ctrl+Z and Ctrl+Shift+Z / Ctrl+Y (not while typing in a text field, where the browser undoes the typing). The last 20 recorded changes are kept (compressed, in the magazine's `undo/` folder) and each button's tooltip names the change it would undo or redo. More changes are now recorded: approving/rejecting or editing an article, moving or resizing a region, drawing a region, re-reading a page, setting or releasing a page's reading order, *Fix reading order* and *Clean up boxes*, on top of region edits, linking, auto-fix and spelling corrections. A new change ends the redo history. As before, an undo (or redo) is refused if something else changed the magazine in between, so it can never roll back work it does not know about (`GET /history`, `POST /undo`, `POST /redo`).
 ### Changed
 - **The Contents button is the first item of the sticky review bar**, so it stays in reach while scrolling a long page.
 - **The page thumbnail is the Review button.** In the thumbnail grid, clicking the (big) page image opens the page in review; the separate *Review* / *Review this page* buttons are gone. A page shared by two or more articles keeps one labelled *Review* button per article, so it stays clear which is meant.
 - **Click a flagged word to correct it yourself.** In the spelling list, clicking the underlined word (or *Edit…*) turns the row into a small editor prefilled with the word: type the correction — one word or several, e.g. `dasich` → `das ich` — and press Enter (Escape cancels). Until now only the listed suggestions could be applied. The server accepts any short single-line text without markup for a correction you type; model answers still go through the strict check.
 ### Fixed
 - **The new-box popup is no longer cut off.** Drawing a box near the bottom of a page put the *Region type / Add region* panel below the window edge. It is now placed in the window: below the box when it fits, above it otherwise, always fully inside, and it follows the box when the page scrolls.
 - **Changed scripts and stylesheets now reach the browser immediately.** They were requested under a version that only moved at release time (`…js?v=1.53.4`) and cached as immutable for a year, so a browser or proxy could keep running old code after an update (a button added to a script simply did not appear). The app shell now requests every asset under `<version>-<build id>`, where the build id follows the newest script/stylesheet/manifest change.
 - **An approved page is no longer purple.** A page the quality check flagged stayed purple even after you approved its article; now your approval wins and the page shows its review colour (the warning badge on the card still lists what the check found). Purple means flagged *and* nobody has approved anything on the page. An old MP3 on an article nobody approved (left over from before pages were linked) no longer turns a page green either: audio only counts for approved articles.
 - **Reading order is now applied automatically after import, *OCR again* and every per-page fix**, not only by the manual *Fix reading order* button. Until now the order after import was whatever the vision/LLM step returned, so a column's short last box could be read after the whole other column; on the measured issue 101 of 204 pages had a saved order that differs from the column-aware order. Pages whose order you fixed by hand stay untouched, except after *OCR again*, when every region is new and a hand order can no longer apply.
 - **The review list shows each region's whole text**, not the first 220 characters, so every misspelling gets its red wavy underline (like a word processor). The engine's `[Non-Text]` marker and hairline boxes (under 3 pt tall) are now treated as OCR noise by *Clean up boxes* and after a page re-OCR, so they no longer show up as near-invisible regions. Fitted boxes keep a little air on grown sides.
 - **The quality check no longer flags correct text as "suspect OCR".** The word check guessed the language per fragment (`iPhones statt Token` read as English) and flagged valid German; it now uses the page's language, the same lenient German rules as the spellchecker, and treats words that recur on the page (names, brands) as vocabulary. Page 61 of the measured issue went from 11 suspect regions to 3 (one a genuinely truncated word), and the issue from 758 to 610 before the language fix's full effect.
 - Suspended compounds (`Programmier- und Hausaufgaben`) no longer lose their hyphen when regions are merged or layouts are grouped; already-ingested `Programmierund` shows in the spelling list with a one-click repair.
 ### Changed
 - `prepare_text_for_tts` accepts the article language and glossary; narration no longer guesses the language per fragment.

 ### What is wrong on this page, and fixing it automatically
 **Purpose:** see at a glance what is wrong with a page and fix it without hunting for the right button.
 **Steps:** open a page in review. The **What is wrong on this page** panel lists each problem in plain language and marks it on the page: **red dashed frame** = printed text outside any box (never read); **orange edge** = a box edge cutting through text; **purple dashed outline** = two boxes over the same text; **yellow dotted outline** = words that look mis-read; **red wavy underline** (in the list) = words no dictionary knows. Each row has its own button (*Find missed text*, *Fit boxes to the text*, *Verify OCR text*, *Fix with language model*). **Fix this page automatically** does all of them in one go: fits boxes, adds an inset pull quote, cuts a paragraph that wraps around it, finds missed text, re-reads suspicious words and, when a language model is configured, fixes provable misspellings.
 **Result:** the page reloads with what was fixed; **Undo** (above the list) restores the page as it was. Overlapping boxes have no automatic fix: delete or merge one.
 **Where an article ends:** the last box says *article ends* only when the article is signed off (`(rah) et`) or a headline/deck/byline follows it (same page or top of the next). Otherwise it shows *no end marker — link page N ›*; click it to add the text of that page that carries the article on (Undo reverses it).
 **Reading order:** applied automatically after import, *OCR again* and *Fix this page automatically*; pages whose order you set by hand keep it (*Automatic order* releases a page).
 **Text flow:** green arrows and chips on the page show where the article carries on: an arrow to the next box below, a curved *next column* arrow, and a chip *continues on page N ›* / *‹ from page N*, plus *article starts / ends*. Tick or untick **Show text flow** to hide them. In the reading view a small marker (`↓`, `col ›`, `p.N ›`) sits at the word where a paragraph crosses a box, column or page. The markers are labelled for screen readers.
 **Whole magazine:** a fresh import now runs this automatically as its last step -- the magazine you open is already as fixed as the machine can make it. **Auto-fix all pages** (contents view, formerly *Quality check / run*) repeats it on demand (for instance after a manual box edit) and lists the pages that still need a look (purple badges).
 **Errors:** a failed fix shows the reason and changes nothing. **Offline / privacy:** the box fixes and the audit are local; the OCR re-read and spelling steps use only the engines you configured.
 **Colours in the article list:** a **blue** row with a *not reviewed* pill is an article nobody has approved or rejected yet; a green edge means approved.
 ### Undo and Redo
 **Purpose:** take back a change (or put it back) without leaving review.
 **Steps:** use **Undo** / **Redo** in the sticky bar (at the left of its second row), or Ctrl+Z / Ctrl+Shift+Z (Ctrl+Y). The button tooltip names the change, e.g. "Undo: Deleted 2 regions". The last 20 recorded changes are kept per magazine: region edits and moves, drawing a region, approving/rejecting an article, page linking, auto-fix, reading-order changes, box clean-up and spelling corrections.
 **Errors:** a button stays disabled when there is nothing to undo/redo, or when something else has changed the magazine since (for example a whole-magazine run), because undoing then would roll that work back too. A new change ends the redo history.
 **Privacy:** the saved states live in the magazine's own `undo/` folder; nothing is sent anywhere.
 ### Less manual work: what happens automatically
 At import (as its automatic last step, not a separate click any more), and whenever you press **Auto-fix all pages**: boxes are fitted, inset pull quotes found, wrapped paragraphs cut, continuation pages **linked into the article running from the page before**, missed text added, suspicious words re-read and (with a language model) provable misspellings fixed. The report then lists only the pages that need a *decision about their boxes*, with **Start with page N**; pages that only have words to check are collapsed and optional. Articles that gained pages go back to *detected*, so re-approve them (the batch tools in *Select* do many at once). A backup of the layout is kept. The ingest status bar keeps showing progress ("Checking page N of M: …") through this step, so a fresh import simply takes longer before it says done -- an Auto-fix failure (for example an unreachable OCR engine) is reported as an ingest failure rather than a silent gap, but nothing already imported is lost.
 **When the automatic link misses:** open the article in review and use **Link to page N** in the panel: *Article continues there* adds the text that belongs on that page (from the paragraph that carries the sentence on, up to the next headline), *Article starts there* adds the opening. Added text is ticked, so untick what does not belong. **Undo** reverses it.
 ### Clean up boxes: fitting boxes to the text
 **Clean up boxes** (review toolbar) also fits each text box to the ink of its text: a side that cuts through letters grows a little, empty margin is trimmed. Boxes you drew or resized are never changed; a backup of the layout is kept and the message reports how many boxes were fitted.
 **Inset pull quotes:** a quote set into the text in a display colour is added as its own *pull quote* region (unticked, never read aloud) by **OCR again (this page)** and **Clean up boxes**. If a picture or infographic is picked up by mistake, delete the region or change its type.
 ### One paragraph, one block — even across columns and pages
 **Purpose:** a paragraph that continues into the next column or onto a later page is separate regions in the layout. Reading and the MP3 join them before splitting into sentences, so narration never stops mid-sentence at a seam.
 **Prerequisites:** none — this happens automatically for every approved article.
 **How it works:** consecutive body regions are joined when the first one does not end a sentence and the next one continues it (lower-case start, trailing hyphen or comma, or ending on an article/preposition/conjunction). A word split at the seam is closed up (`jähr-` + `lich` → `jährlich`); a real compound hyphen is kept (`KI-` + `Modelle`). Headings, interview turns and finished paragraphs are never glued together, and a caption or figure description between two fragments is moved after the paragraph.
 **Result:** the reading view and the exported MP3 speak the fused paragraph as one block; highlighting and "Original page" still follow the region each sentence started in.
 **Errors:** if two paragraphs are wrongly joined or a split is missed, correct the region text or reading order in review; the text is recomputed each time.
 **Mobile / accessibility / offline / privacy:** no extra controls; nothing leaves the machine.
 ### Pronunciation & spelling (per article)
 Open an article and expand **Pronunciation & spelling** under the player.
 **Acronyms — purpose:** say `NAS`, `ML` or `SSD` the way a listener expects, in the article's language. The language is decided once for the whole article (a short fragment alone is a poor signal); an English quotation inside a German article is spoken with English expansions.
 **Steps:** unfamiliar acronyms are listed with the sentence they appear in. Type how the narrator should say one (empty = as printed) — the change applies immediately and stays with the article — or press **Let the language model decide**: it picks *expansion*, *letter by letter* or *as a word* from the sentence's context and, for English acronyms in a German article, prefers the established German term. Only expansions carry model-written words; letters/word choices are decided by the server.
 **Known acronyms:** a built-in list covers common German and English ones (`KI`, `AI`, `LLM`, `API`, `GPU`, `USB` → "U S B", `HDMI`, `z. B.` …). The displayed text is never changed.
 **Spelling — purpose:** find OCR and typing errors in German and English text without ever rewriting names or technical terms by guess.
 **What is flagged:** a word unknown in the text's language, not a known compound (`Softwareentwicklung`), not known in the *other* language (an English term inside a German article is fine), not an acronym, not a name in mid-sentence English, and not a word you kept. A word that recurs three or more times is treated as vocabulary.
 **Marked on the page:** in review, flagged words are underlined in the region list and the **Spelling** button lists them for the page with suggestions. In the reading view the same list is under **Pronunciation & spelling**. Click a suggestion to correct the word in the region text (review offers **Undo**), or **Keep** to add it to this issue's dictionary.
 **Fixed by an agent:** **Fix with language model** (page or article) asks the configured LLM about each flagged word with its sentence. A correction is applied only if it is one of the dictionary's suggestions or a single known word within two edits of the printed one; names and terms the model keeps go into the issue's dictionary, everything else stays marked. The whole-magazine **Quality check / run** does the same for every page (when an LLM is configured) and lists pages that still have marked words.
 **Errors:** "No LLM model configured" — set one in Settings; the marked list still works without it. A stale suggestion ("the text has changed") — reload the list.
 **Mobile / accessibility:** the lists are ordinary buttons with labels ("Replace X with Y"); marks are underlined, not colour-only.
 **Privacy:** the agent sends only the flagged word and its surrounding sentence to the LLM you configured in Settings; without an LLM nothing leaves the machine.
 ### Find an issue online
 **Purpose.** Pull a magazine issue into the app without leaving for a browser and uploading by hand.
 **Prerequisites.** Internet access for the Internet Archive; for your own library, an OPDS catalogue
 (Calibre-Web, Kavita or Komga all serve one) added under `magazine_opds_catalogs` in the app settings as
 `[{"name": "NAS", "url": "http://nas.local:8083/opds/"}]`. Catalogues that need a login are not supported yet.
 **Steps.**
 1. Open Magazines. In *Find an issue online* pick a source, type a title or subject, press Search.
 2. Read the licence line on each result. The source states it, the app does not judge it.
 3. Press *Import* on a result. The PDF downloads (progress is announced under the search box), the magazine
   opens and ingestion starts, exactly as after an upload.
 **Expected result.** A new magazine project with the PDF stored locally, then the normal review-before-narration flow.
 **Errors.** A source that is down, rate-limiting or returns something other than a PDF gives a plain message
 under the search box and nothing is created that you must clean up beyond the empty project shown in your library.
 Lending-only Internet Archive items are never listed. Only one download runs at a time; a PDF larger than
 400 MB is refused.
 **Mobile / accessibility.** The form stacks on a phone; results are a list with labelled Import buttons; status
 text is a polite live region, so a screen reader hears "N results" and download progress.
 **Offline.** Search and import need the network; everything after import works offline.
 **Privacy.** Your search words go to the chosen source (archive.org, or your own catalogue). Nothing else is
 sent. Websites that redistribute commercial magazines without a licence are deliberately not supported.
 ### Quality check / run (whole magazine)
 **Purpose:** find every page where text is not inside a box, boxes overlap or cut off letters, or OCR still looks wrong.

 ### Magazine MP3 quality pass, part 2 — set 2026-09-28
 Findings from the first whole-issue quality run. Every issue found must either be
 fixed by an agent (vision re-read / LLM adjudication, never a blind rewrite) or be
 marked on the page for a human. Order of work:
 1. [x] **Fuse one article's paragraphs into single narration blocks.** A paragraph
   that continues into the next column or onto a later page is separate regions today,
   so playback and the MP3 split the sentence at the seam. Join the fragments into one
   block (keeping the source regions for highlighting) before sentence splitting.
 2. [x] **Context-aware acronym converter.** Use the article's language (not a
   per-fragment guess) and a per-article glossary: known acronyms come from the
   pronunciation database, unknown ones are classified by the LLM from their sentence
   (expansion / spelled letters / read as a word) and stay editable.
 3. [x] **German and English spellchecker with fix-or-mark.** Per-block language,
   tokens unknown in both dictionaries and the user's own dictionary are findings;
   a vision re-read and an LLM adjudication fix what they can prove, everything left
   is marked on the page with suggestions (accept / ignore / add to dictionary).
 ### Magazine: verify, re-import and compare — set 2026-09-28
 The current issue (c't KI-Wissen 2026) is the test bed. The point is to measure whether the newest
 rules beat what was built up by hand, and to feed every difference back into the rules. Do these in order.
 - [x] **A — Finish verifying this magazine (automatic part).** 2026-09-28: full Auto-fix with the language
  model (thinking off, ~4s/call) and vision re-read ran to completion: 94 misspellings fixed, 77 marked,
  52 blocks linked, 27 pages still need a human decision. Snapshot after this run is
  `config/magazine_backups/bd871c7c22f0449984d3b0e3d603d6d6-after-autofix-20260928-1810`.
  **Healing re-run with both G fixes, 2026-09-29** (~17 min; the same "Auto-fix all pages" the user runs by
  hand, triggered once to apply the two fixes retroactively): re-running `clean_up_regions` on the result
  found **0** additional duplicates, confirming the 6 residual ones found before this run are gone. Also
  surfaced (pre-existing behaviour, not part of either fix) one duplicate **article** pair sharing page 75
  (`article-020` "AVRunner im nächsten Desinfec't" / `article-021` "Wofür Softwareentwickler KI-Tools
  nutzen", both approved) -- added to the pages needing review, since resolving two approved articles that
  both claim the same page is a human decision. **Still open:** a human must work the 27 flagged pages
  (same list as before, plus this new duplicate-article pair), approve/reject the not-reviewed articles,
  and decide which of article-020/021 page 75 actually belongs to.
 - [x] **B — Make a backup copy.** Taken 2026-09-28 after A's automatic pass (see snapshot above; layout,
  articles, dictionary, quality report; 62 articles). Audio stays in the earlier 17:33 snapshot.
 - [x] **C — Clone the PDF and re-import it.** Cloned as doc `345b2a841f104b03b3cdf61faceb66cc` from the same
  `source.pdf`, ingested from nothing (no reuse of the reviewed layout).
 - [x] **D — Process the new import to the maximum.** Full ingest (~2h27m) + Auto-fix with LLM and vision
  (~35m) on the clone. Result: 60 pages need a decision (vs. 27 for the hand-reviewed magazine) -- expected,
  since the backup carries months of manual box/order/approval fixes a from-scratch run cannot reproduce.
 - [x] **E — Compare the new result with the backup.** Ran `scripts/compare_magazines.py`; report saved at
  `architecture/evidence/compare-345b2a84-vs-backup-20260928.{md,json}`. Headline: text similarity 0.937,
  box recall/precision 0.88/0.85, reading-order agreement 0.967, 51/56 articles matched.
 - [x] **F — Show the differences and decide what is better.** Decided not needed: a side-by-side review UI
  adds no value the markdown/JSON report from E doesn't already give for this workflow.
 - [~] **G — Adjust the rules so the next magazine needs less work.** Two universal fixes landed 2026-09-28/29,
  each traced from the worst-differing pages E flagged, not from one page in isolation:
  1. **Vision refusal hallucinations** (pages 82, 87, 124, 202): the vision OCR engine sometimes answers
     with a sentence describing its own failure ("The image is too blurry to recognize...", "The Ground
     Truth image displays...") instead of leaving an unreadable photo/screenshot region empty, tiled across
     dozens of regions and narrated as real page text. Fixed in `core/magazine.py`
     (`_drop_repeated_region_text`/`_looks_like_vision_refusal`): text repeated verbatim across 3+ regions
     that also reads like a refusal is blanked before it becomes blocks. Verified live: re-OCR of page 82
     discarded 29 hallucinated regions, page 87 discarded 122.
  2. **Duplicate check runs too early** (pages 31, 42, 103, 151, 152, and 6 more on the already-reviewed
     backup): the duplicate-box detector (`clean_up_regions`) only ran once, before the box-fitting/seam-
     mending loop that can grow or merge a box afterward -- a box that becomes a duplicate only because of
     that growth was left unmarked, so its text was narrated twice. Fixed by re-running the check after that
     loop at ingest, and again after `recover_missing_text` in the whole-issue quality run
     (`routes/magazine.py`). Verified live: re-running the check on the current layout alone found 13 such
     duplicates in the fresh import and 6 in the already-reviewed backup (the bug predates this fix, so the
     backup itself is not clean either -- its next Auto-fix/quality run will self-heal now).
  Regression tests: `tests/test_magazine.py::VisionOcrRefusalHallucinationTests`,
  `tests/test_magazine_routes.py::QualityRunJobTests::test_a_duplicate_created_by_recovering_missing_text_is_still_caught`,
  `tests/test_magazine_routes.py::IngestSyncDuplicateRecheckTests`.
  **D→E re-run with both fixes, 2026-09-29** (re-running Auto-fix on the same clone; report at
  `architecture/evidence/compare-345b2a84-vs-backup-20260929-after-fixes.{md,json}`): pages needing a
  decision 60→53, overlapping pairs 188→14, clipped edges 127→96 -- real improvement. Narratable word
  count also dropped slightly (68680→64946), consistent with duplicate text no longer being counted twice.
  Caveat: this re-run's own "re-reading suspicious words" step calls the vision engine again on flagged
  boxes, and that engine is not deterministic -- pages 82 and 87 got *worse* on this pass (re-hallucinated
  differently) for reasons unrelated to either fix, which is why some individual pages regressed even as
  the totals improved. A from-scratch re-ingest (true D) would be a cleaner test but costs ~2h27m; not run
  again this pass.
  **Still open:** page 44's screenshot-in-article OCR (garbled but partly real transcription of a mockup
  image) was looked at and deliberately left alone -- a known-word-ratio filter would also catch genuine
  quoted text, and no reliable rule to tell them apart was found; page 3's biggest "difference" turned out
  to be baseline swallowing real editorial text into a figure's alt text, i.e. new is better there, not a
  regression to fix. A decision on whether to run the healed quality pass on the live production magazine
  (6 residual duplicates found there, not yet corrected) is still open.
  **Ingest now runs Auto-fix itself, 2026-09-29.** A fresh import used to stop laid out but not worked,
  leaving Auto-fix for a separate manual click; `_ingest_sync` now runs `_quality_run_sync` itself under
  the same job (`routes/magazine.py`), so a fresh import opens already-fixed. An Auto-fix failure is
  reported as an ingest failure without losing the ingest's own result. Regression tests:
  `tests/test_magazine_routes.py::IngestSyncAutoQualityRunTests`.
  **Clean from-scratch re-ingest, 2026-09-29** (doc `64fe2b4def774c29a44c14a5c4d35571`, both fixes and the
  auto-chained Auto-fix in place; ~2h39m combined; report at
  `architecture/evidence/compare-64fe2b4d-vs-backup-20260929-fresh-reingest.{md,json}`): the ingest-time
  ordering fix is proven in isolation -- re-running `clean_up_regions` on the finished layout found **0**
  additional duplicates (13 were found this way on the previous, unfixed clone). The hallucination filter
  also fired identically (29 + 122 regions discarded on pages 82/87, matching the first run). But the
  whole-magazine comparison against the backup came back worse than the previous clone's (76 pages needing
  a decision vs. 53, overlapping pairs 170 vs. 14) for two traced, non-regression reasons: (1) the vision
  OCR engine is not deterministic across independent full-magazine passes -- already seen with pages 82/87
  specifically; (2) `scripts/compare_magazines.py` was comparing pages the backup has hand-marked as
  full-page advertisements (skipped by its quality run) against the same pages freshly OCR'd in the new
  import, which had never had that one-time manual step -- a review-state difference, not a pipeline one.
  Fixed (2): the compare tool now excludes any page either side calls an advertisement from every
  difference statistic, reporting the count separately instead (`pages_skipped_as_advertisement`; 18 on
  this pair). Regression tests: `tests/test_compare_magazines.py` (advertisement handling). Re-run with the
  fix: text similarity 0.837→0.870, box precision 0.62→0.66 -- a real but partial improvement, confirming
  (1) still accounts for most of the remaining gap. Not fixable here: engine non-determinism is a property
  of the external OCR service, not this pipeline; a fair A/B would need the same fixed OCR responses on
  both sides, which the current tooling has no way to freeze.
 ### Voice Studio (github.com/debpalash/voicestudio) — evaluation, container, comparison
 - [x] **1 — Study Voice Studio.** 2026-09-29: read the repo (README, LICENSE-NOTICE.md, feature-catalog.md,
  engines/README.md, speech-platform.md, performance.md, mcp.md, docker.md) and the GitHub API record
  (46.2k stars, 3,470+ commits, pushed today, license `AGPL-3.0-only` — quoted exactly from the API, not
  the fetch tool's summary). AGPL-3.0: commercial use of the app is explicitly allowed; the Affero clause
  only applies to a *modified* version offered to others over a network. No scraping beyond the repo's own
  published files and its `/health` endpoint.
 - [x] **2 — Run it as a Docker container.** Already running (user's own doing, confirmed live, not started
  by this session): `http://192.168.178.8:3900/` on the same DGX Spark this app runs on --
  `GET /health` → `{"status":"ok","device":"cuda (NVIDIA GB10)","version":"0.5.6"}`. Real, non-hypothetical
  risk noted in the comparison doc: it shares the DGX's one GPU with this app's Qwen3-TTS/vision-OCR/LLM
  calls, so a heavy VoiceStudio job and a magazine Auto-fix run at the same time will contend for VRAM.
 - [x] **3 — Detailed comparison with this software.** Written up at
  `architecture/voicestudio-comparison.md`: side-by-side table, what each is ahead on, the shared-GPU risk,
  and a narrow recommendation (not a replacement -- the magazine pipeline has no counterpart in VoiceStudio
  to compare against; worth revisiting only as an alternate TTS backend for a second opinion on narration
  quality, or its MCP server for a quick engine A/B). No integration started.
 ### UI/UX and feature ideas from the VoiceStudio comparison — set 2026-09-29
 From the deep-dive UI/UX comparison (`architecture/voicestudio-comparison.md`, "UI/UX and
 feature-parity deep dive"). User picked these to build; telephony integrations (Twilio/
 Plivo/Telnyx) were in the same gap list but deliberately not picked -- leave that one alone.
 - [ ] **Projects menu: group Audiobooks, Magazines, Script Rehearsals and Video Dubbing
  under one "Projects" nav section.** Currently `Reader` (audiobook), `Magazine` and
  `Rehearser` are three separate top-level `nav-tree-head` sections in the sidebar
  (`static/index.html`/served nav — see `data-nav-section="s-reader"` /
  `"s-magazine"` / `"s-rehearser"`). Add a new "Projects" parent with these three as
  submenu items, plus a fourth submenu item for the new Video Dubbing feature below (a
  placeholder entry is fine until that feature exists, but say so in its UI rather than
  linking to nothing silently). Update `Manual.md`'s navigation description and any
  Playwright specs that assert the current nav structure.
 - [ ] **Video Dubbing feature.** New capability, not currently in this app at all: upload a
  video/audio file or paste a URL, transcribe it, translate to a target language (offer a
  local/offline model, not only an LLM call -- see VoiceStudio's NLLB-200 option), then
  re-synthesize speech timed to the original and mux it back into the video. This is a
  multi-day feature (needs its own data model, a job pipeline, and a review UI, likely
  similar in shape to the magazine pipeline's box/undo conventions) -- plan it properly
  (goals, data model, API contract, error/offline behaviour) before implementing, per the
  planning workflow, rather than bolting it onto an existing route file.
 - [ ] **Live STT Dictation.** A global hotkey that starts listening, transcribes speech, and
  inserts the resulting text into whatever field/app currently has focus -- distinct from
  the existing "global hotkey daemon" in Connect Apps, which triggers TTS *playback*, not
  speech-to-text insertion; do not conflate the two or reuse its name for this. Needs a
  small native/OS-level component (focus capture, text insertion) similar in spirit to
  VoiceStudio's Rust control sidecar -- decide the platform(s) to support first (this
  household's own machines) rather than building a generic cross-platform solution
  speculatively.
 - [ ] **Onboarding / setup wizard.** Either (a) detect the local stack already configured
  (Qwen3-TTS, vision OCR, the LLM router -- these already have URLs in Settings) and walk a
  new install through pointing at them with a live check per engine, or (b) a single
  one-click installer/setup flow that provisions everything needed, mirroring VoiceStudio's
  tiered model packs (Fast/Balanced/Quality/Max, disk size shown before committing). Decide
  which of (a)/(b) fits this app's actual deployment story (self-hosted, one household, engines
  usually already running on the DGX) before building -- (a) is likely the better fit and
  the smaller change; (b) only makes sense if this app starts bundling/installing its own
  models rather than calling existing engine URLs.
 - [ ] **Global command palette + cross-app "recent" history.** A `Ctrl`/`Cmd`+`K` palette to
  jump to any section/action, and a unified "recent generations" view spanning Voice Clone/
  Design/Conversation/Magazine/Reader, not just each feature's own history (the magazine's
  20-step undo stack stays separate -- this is about *finding* a past generation across
  features, not undoing one). Survey existing per-feature history/list endpoints first
  (`/api/*/history`-shaped routes already exist for several features) so the palette reuses
  them rather than duplicating state.
 - [ ] **Curated voice-design preset gallery, integrated into the existing preset system.**
  `s-design.html` already has save/load/delete for named presets (`design-preset-*`,
  `routes` behind `design-preset-save`/`-load`/`-delete`) -- add a small built-in gallery of
  named example personas (in VoiceStudio's style: "The Librarian", "The Anchor", …), each
  with a one-line pitch and a pre-rendered demo clip, "Use this design →" filling the
  description box from it. Ship a handful covering common needs (audiobook narrator, news
  anchor, casual conversational, storyteller) rather than trying to match VoiceStudio's
  exact catalog. Generate and store the demo clips once (not on every page load) and keep
  them small (the existing 24 kHz mono WAV convention).
 - [ ] **General UI/UX simplification pass -- reduce how overwhelming this app's settings/
  configuration screens are.** User's own observation comparing live: VoiceStudio's
  integrations screen (`http://192.168.178.8:3900/#/integrations`) is "way cleaner" than
  this app's Settings/Engines equivalent. Concrete evidence for the gap: `s-llms.html`
  ("Engines") is 880 lines with 31+ labelled fields all visible on one page at once, versus
  VoiceStudio's per-category model cards (TTS/ASR/Dictation/Diarisation/Translation/LLM)
  that each expand on demand -- see the `models.png` screenshot referenced in
  `architecture/voicestudio-comparison.md`. Direction: progressive disclosure (group into
  collapsed cards/categories, expand one at a time) instead of one long flat form; fewer
  fields visible per step; a simpler default view with advanced options tucked behind a
  toggle, mirroring the "Fast/Balanced/Quality/Max" tiering idea from the onboarding-wizard
  item above rather than exposing every knob unconditionally. Not limited to Engines --
  once a pattern is settled there, audit Settings' other pages and any other dense
  single-page form (Payloads, the magazine quality-run's settings, etc.) against it. Needs
  its own before/after review with the user (screenshots or a walkthrough) since "simpler"
  is a judgement call, not a number to hit.

 # OCR candidate benchmark — 2026-09-29
 Harness: `scripts/bench_ocr.py`. Corpus: *c't KI Wissen 2026* (native text layer, 204 pages). Six evenly spaced
 pages with at least 250 words (5, 32, 67, 101, 138, 169), rendered at 110 dpi (the app's ingest default). The
 PDF's own text layer is the ground truth. Raw numbers: `bench_*.json` (metrics only, no magazine text).
 | Engine | Where it ran | Mean word F1 | Seq. similarity | Median s/page | Memory | Licence |
 |---|---|---:|---:|---:|---|---|
 | tesseract deu+eng (current last resort) | CPU, app container | 0.880 | 0.841 | 2.2 | negligible | Apache-2.0 |
 | baidu/Unlimited-OCR (current primary) | GPU container, port 8098 | 0.865 (5/6 pages) | 0.865 | 44.1 | see `docker stats` | as published |
 | docling (default pipeline + RapidOCR) | CPU, venv | 0.867 | 0.783 | 8.9 (first page 66 s warm-up) | 2.4 GB RSS | MIT |
 | PaddleOCR 3.2 (PP-OCRv6 medium, `de`) | CPU, venv | 0.881 | 0.551 | 36.5 | 1.4 GB RSS | Apache-2.0 |
 | DeepSeek-OCR | **not run** | | | | ~7 GB weights | MIT |
 | Qwen3-VL-30B-A3B-Instruct-FP8 | **not run** | | | | ~30 GB weights | Apache-2.0 |
 | KDL-Frontier-Parser-nano (current fallback) | **not run**: container exited (137) 6 days ago | | | | | |
 Metrics: *word F1* is order-insensitive overlap of lower-cased word tokens; *sequence similarity* is a difflib ratio
 over the token sequence and so also rewards correct reading order. Both are capped below 1.0 by things a text layer
 contains that a page transcription need not (running heads, hyphenation, sidebars), so compare engines to each other,
 not to 1.0.
 ## Reading
 - **Plain transcription accuracy is a wash.** Every engine lands at F1 0.865–0.881 on these pages; the differences are
  within page-to-page variation (0.77–0.96). Nothing here justifies replacing tesseract for text quality alone.
 - **Speed differs by 20×.** Tesseract 2.2 s/page beats the GPU vision engine (44 s/page) and both CPU candidates.
  The vision engine also returned nothing for one of six pages (page 101), which the app's fallback chain absorbs.
 - **What the heavier engines add is structure, not characters:** Unlimited-OCR labels regions and furniture,
  docling returns layout-ordered text (sequence similarity 0.78 vs PaddleOCR's 0.55, which is raw line order).
  Neither is scored here; the app's own layout stage already does this work, so the case for a candidate rests on
  region/table/figure quality, which needs a different benchmark (labelled boxes), not this one.
 - **Open-ended figure description** (the harder requirement in TODO) is untested: none of the engines run here is a
  captioning model, and the two that are (DeepSeek-OCR, Qwen3-VL) could not be loaded — see below.
 ## Why two candidates were not run
 The host has 121 GB of unified memory with about 107 GB in use (the running sglang model dominates; GPU and system
 memory are the same pool on this machine), leaving roughly 14 GB. Qwen3-VL-30B FP8 (~30 GB) cannot be loaded without
 stopping another model, and DeepSeek-OCR (~7 GB, pinned dependencies on a GB10 GPU) would leave almost no margin: an
 out-of-memory kill there could take down the running stack. Both need a decision from the owner: which running model to
 stop for a test window.
 ## Caveats
 Six pages of one German-language, native-text magazine; CPU timings for docling and PaddleOCR (both would be faster on
 GPU); one run each. Enough to rule out an obvious accuracy win, not to pick a winner for scanned or image-heavy issues —
 this magazine's pages are born-digital, so a scanned issue would separate the engines more.

@ -57,6 +57,35 @@ box over unrelated copy between the two pieces (seen repeatedly on pages 111
 and 114 of the measured c't issue). Fragments within one column are still
 merged; only a genuine column transition remains as two boxes.
 ### Narration text: fusion, language, acronyms, spelling
 `article_text(..., fuse=True, glossary=...)` is the single source of narratable text for the reader, the podcast
 source and the MP3 export.
 - **Fusion** (`fuse_paragraph_blocks`). A body paragraph that flows into another column or page is separate
  regions; joining them before sentence splitting stops narration at the seam. `paragraph_continues` joins when the
  previous fragment has no sentence-ending punctuation and the next starts lower-case, the previous ends in a hyphen or
  comma, or it ends on an article/preposition/conjunction (German nouns are capitalised, so lower-case alone is not
  enough). Titles, headings, bylines, interview turns (`Label: ...`) and finished paragraphs never fuse. Captions and
  figure descriptions between fragments are emitted after the paragraph. A fused block keeps the first region's
  id/page/bbox plus `parts` (id, page, bbox, start, end offsets) so the player highlights and jumps to the region each
  sentence began in. A hyphen at the seam is dropped for a printed line break and kept for a real compound (`KI-` +
  `Modelle`), and the rebuilt word goes through the umlaut repair again.
 - **Language** is decided once per article (`detect_article_language`), then overridden per block only when that block
  is decisively the other language (`language_for_block`: at least 12 words and three hits for one language, none for
  the other).
 - **Acronyms.** `core/pronunciations.json` holds per-language expansions and letter-spelled lists; an article's
  `glossary` (in `articles.json`) is applied on top and wins. Unknown all-caps tokens (`find_unknown_acronyms`) are
  shown with their sentence; the LLM classifies them as expansion / letters / word (`parse_acronym_decisions`): only
  `expansion` carries model text, `letters` and `word` are produced server-side, and answers for acronyms that were not
  asked about are dropped. The displayed text is never altered — only `spoken_text`.
 - **Spelling** (`core/spelling.py`). Findings, not rewrites: a word unknown in its language and in the other one, not a
  compound of known parts (`is_known_compound`), not an acronym or camelCase brand, not in the issue's
  `dictionary.json`, and not recurring three times. `accept_agent_fix` is the only path by which a model's answer edits
  text: the replacement must be a dictionary suggestion or a single known word within two edits, and offsets are
  re-verified against the current text (`apply_fix`). The whole-issue quality run applies the same agent per page and
  reports remaining words per page (`spelling`, `spelling_fixed`).
 ### Why server-side, not in the browser
 Text extraction for plain PDFs runs client-side (PDF.js), and that stays. Layout

 # Magazine sources (find and import an issue)
 Status: implemented (core/magazine_sources.py, routes/magazine_sources.py, magazine.js "Find an issue online").
 ## Goal
 Search legitimate catalogues from inside the app and import an issue as a normal magazine project. Ingestion
 stays a separate, existing step, so nothing is narrated before the review.
 ## Providers (one interface: `search`, `resolve_pdf`, `allowed_host`)
 | Provider | Kind | Notes |
 |---|---|---|
 | Internet Archive | fixed | documented advanced-search + metadata API; loan-only items excluded (`-access-restricted-item`); prefers the original PDF over derived text PDFs |
 | OPDS catalogue | user-configured (`magazine_opds_catalogs` setting) | standard Atom feed; search via the catalogue's own OpenSearch template; only PDF acquisition links |
 Deliberately unsupported: sites that redistribute commercial titles without the publisher's licence (see TODO.md).
 Candidates later: publisher free issues / feeds, DOAJ/arXiv/PMC. Each would be another provider.
 ## API
 - `GET /api/magazine-sources` -> `{sources:[{key,label,kind}]}`
 - `GET /api/magazine-sources/{key}/search?q=&page=` -> `{items:[{id,title,author,date,summary,license,page_url,thumb_url}]}`; 404 unknown source, 502 with a safe message when the source fails
 - `POST /api/magazine-sources/import {source,item_id,title}` -> `{id,job_id}`; the download runs as a background job (`magazine-source-import`, poll `/api/jobs/{id}`); 409 while another import runs
 ## Security boundaries
 - SSRF: a download is fetched only from the provider's own host (archive.org, or the catalogue's host). Item ids are validated (IA identifier regex; OPDS id must be same-host). Redirects are followed manually and re-checked.
 - XML: feeds with a DOCTYPE or entity declaration are refused (billion-laughs / XXE class); feed size capped at 4 MB.
 - Limits: 400 MB per PDF, connect/read timeouts, one import at a time, `%PDF` magic checked on the first chunk, temp file removed on failure.
 - No credentials are stored or sent; catalogue URLs with embedded credentials are rejected.
 - Remote text is rendered as text in the UI (escaped), links open with `noopener noreferrer`.
 - Rate limits/terms: the Internet Archive asks for a descriptive User-Agent and modest request rates; searches are user-initiated, one page of 20 per request.
 ## Error behaviour
 Every provider failure is a `SourceError` with a user-safe message (unreachable, HTTP status, rate-limited, not a PDF, too large, different host).
 ## Offline / sync
 Needs the network only for search and download. No synchronisation state.
 ## Known limitations
 OPDS catalogues requiring login; OPDS pagination beyond the first feed page; no thumbnails shown yet (returned in the API).

 # Prompt: bring the tts-voice-creator OCR pipeline's hard-won lessons into another app
 Copy everything below the line into the other project's agent. It is written for an AI coding agent that has
 never seen this repository. Reference implementation (read it, do not blindly copy it):
 `/home/sparky/Docker/tts-voice-creator-clone-and-design-2` — `core/magazine.py` (pure logic, ~5,400 lines),
 `routes/magazine.py` (API and jobs), `static/js/magazine.js` (review UI), `architecture/magazine-ingestion.md`
 (the reasoning), `scripts/bench_ocr.py` (benchmark), `tests/test_magazine.py` (behaviour pinned by tests).
 ---
 ## Your task
 This app already runs OCR. Improve it by adopting the approach below **where it fits this app's documents** — first
 measure, then change. Do not port code wholesale: the reference app OCRs *scanned German-language magazines* for
 audio narration, so some rules are magazine-specific (articles, columns, sidebars) and some are general (everything
 about trusting, verifying, fitting and reviewing OCR output). Sort each item below into *applies / does not apply /
 needs a decision* for this app and tell me before starting the big ones.
 Follow this project's own CLAUDE.md and conventions. Inspect the repo and current OCR code first; preserve
 existing behaviour that works; update docs and tests in the same change; commit per feature; never push without
 being asked.
 ## Step 0 — measure before touching anything
 Build a benchmark first, or every later claim is opinion.
 1. **Ground truth without hand labelling.** Pick documents that have a real text layer (born-digital PDFs), render
   pages to images at the resolution the app really uses, run each OCR engine on the *image*, and score against the
   PDF's own text layer. Score on lower-cased word tokens (join line-end hyphenation first):
   - *bag F1* — order-insensitive overlap of tokens;
   - *sequence similarity* — `difflib.SequenceMatcher` ratio over the token sequence (also rewards correct reading order);
   - seconds per page, and the engine's memory footprint (`docker stats` for a remote engine; process RSS for a library).
   Reference: `scripts/bench_ocr.py`. It scores ~0.87–0.88 F1 for every decent engine on clean pages: the ceiling is
   below 1.0 because a text layer contains running heads and sidebars. **Compare engines to each other, never to 1.0.**
 2. **A second benchmark for structure** (boxes, reading order, region types) needs labelled pages; build a small one
   (10–20 pages) from a document you can correct by hand. Transcription accuracy and layout quality are different
   problems and were solved by different means here.
 3. Record results as JSON (metrics only — no copyrighted or private page text) next to a short README of what was
   measured, when, on what.
 **Lesson from our run (2026-09-29, 6 pages of one issue):** tesseract deu+eng F1 0.880 at 2.2 s/page; Baidu
 Unlimited-OCR (GPU vision model) 0.865 at 44 s/page and returned nothing on 1 of 6 pages; docling on CPU 0.867 at 8.9 s;
 PaddleOCR 3.x on CPU 0.881 at 36 s. **Plain transcription accuracy was a wash across all of them, and the cheapest was
 20× faster.** What the heavy engines add is structure (region labels, furniture detection, layout order), not better
 characters. Check whether that holds on your documents before paying for a heavier engine.
 ## The pipeline shape that worked
 ```
 render page (110 dpi) ─► native text if the PDF has it ─► OCR only where needed ─► regions with bbox
   ─► trust engine labels ─► fit boxes to the ink ─► classify the ambiguous ─► reading order
   ─► clean-up (re-type, never delete) ─► quality audit ─► human review ─► only then use the text
 ```
 ### 1. Escalate per page, not per document
 Use native text when the page has it. Escalate a page to OCR when it has almost no native text (we used < 120
 characters) **or** when its existing text scores badly on a coarse plausibility score (`ocr_quality_score`: share of
 letters vs symbol noise, word shape). The score is deliberately coarse — it separates "mostly symbol noise" from
 "plausible prose" to gate an expensive call; it will **not** catch a single misread inside a good sentence
 (`KI` → `K |`). Do not pretend it does.
 ### 2. A fallback ladder, and every step may fail
 Order: primary vision/layout engine → second engine → local classical OCR (tesseract) → keep whatever text exists.
 Any failure (unreachable, timeout, HTTP error, unparseable, repetition loop) returns `None` and the *next* rung runs.
 OCR must never be the reason a whole import fails. A second engine that returns plain text with no coordinates is
 still useful: wrap it as one full-page "text" region (`_whole_page_region`), gated by the same plausibility score, and
 accept that column structure is lost for that page.
 ### 3. Distrust the model's output in specific, testable ways
 Each of these happened on real pages; each is a small function with tests:
 - **Repetition loops.** A vision model transcribed a chart as "das Produkt, das Produkt, …" for its whole token
  budget. A short phrase repeated ≥ 8× back-to-back = failed call (`_looks_like_repetition_loop`), fall through.
 - **Hallucinated refusals.** Over unreadable photos/screenshots an engine emits "The image is too blurry to
  recognize…". Drop a sentence that repeats across ≥ 3 regions (`_looks_like_vision_refusal`); on our issue this
  removed 29 and 122 hallucinated regions on re-OCR of three pages.
 - **Invented figures.** A layout model may propose a picture/chart/table box where OCR found nothing. Screen every
  invented region against the page's ink density before creating it (`region_looks_like_a_picture`, mean ink ≥ 0.4).
  Measured: invented regions that were really text had 0.10–0.14 mean ink, real photos/charts/tables 0.56–0.97 — a
  wide gap, so the floor is not fine-tuned.
 - **Grounding vs transcription.** Engines transcribe far better than they localise. See "figure bounds" below.
 - Treat a **direct engine label** (footer, title, page number, caption) as authoritative and skip heuristic
  re-classification for it; only ambiguous "text" regions go through your own classifier.
 ### 4. Get figure bounds from the render, not from the engine
 Measured over 138 figure regions: text boxes matched the render closely enough to use as-is, figure boxes were
 routinely offset, undersized, or on the neighbouring column — but the *contents* were right. The model knows **which**
 graphic; the render knows **where it ends**. `snap_visual_bboxes`:
 - reduce the render to an ink grid (10 px cells → inked fraction per cell; body text ≈ 0.25, a photo ≈ 1.0);
 - **two passes**: a strict solid-ink pass (cell ≥ 0.55) anchors on photos/panels; a loose pass (any mark ≥ 0.15,
  ≤ 2 blank cells crossed) grows sparse charts (thin bars, gridlines) that the strict pass would crop;
 - decide connectivity **once** (dilate the solid mask by 3 cells, label components, seed picks the component it
  overlaps most) — picking "the best component of the seed's own raw pieces" made the result depend on seed size and
  was a real bug (a correct box shrank on re-run);
 - a rectangle is not the component's shape: trim edges back to the nearest row/column blocked across ≥ 70% of the
  width/height, or the box swallows unrelated text between two patches;
 - text blocks and every *other* figure's seed are fences (excluded from the mask up front); neighbours re-seed each
  other for up to 6 rounds so the result stops oscillating and is deterministic;
 - accept a result only if it is solidly inked (≥ 0.45) **or** framed on ~90% of its rows and columns (a UI screenshot
  is white inside), never shrinks below 30% of the seed, and **reproduces itself** when fed back (IoU ≥ 0.7);
 - two figures pulled onto one graphic → revert both. A confidently wrong box is worse than a loose one the user sees.
 Result: 98–119 of 147 figure regions corrected, none worse on visual inspection; pale charts on white left alone.
 Make it **idempotent** and re-runnable on existing documents without re-paying for transcription.
 ### 5. Fit text boxes to their ink (small, bounded, geometry-only)
 `snap_text_boxes`: if a side cuts through letters (ink continues just outside it where no other box is) grow it until
 the text ends, by at most ~16 px sideways (70 for headlines, 90 downward); trim empty margin back to the first inked
 line, leaving 2 px of air. Never touch a box a human drew or resized. Never change text. On the measured issue only 5
 of 658 boxes (pages 1–59) needed it — which is the point: measure first, and keep it from ever making a good box worse.
 Related: `mend_column_seams` moves the shared boundary between two vertically stacked boxes to the nearest white gap
 of ≥ 2 blank pixel rows and reads *only the newly covered strip* into the box that gained it; re-check for duplicates
 afterwards because fitting can turn a neighbour into a duplicate.
 ### 6. Clean-up rules: re-type, never delete — and size each rule on real data first
 `clean_up_regions` measured 2,038 boxes before any rule was written:
 | rule | found | left alone on purpose |
 |---|---|---|
 | text ≤ 80 chars and ≥ 90% inside a picture → `in_picture` | 71 | longer text in a picture: it was real running text caught in a loose frame |
 | ≤ 2 alphanumeric characters → `ocr_noise` | 25 | longer short strings: a phone number, a price, a citation |
 | box ≥ 80% inside a bigger box whose text contains ≥ 90% of it → `duplicate` | 38 | the other **333 overlapping pairs hold different text** — hiding one loses text |
 | author line running into the first sentence → split | 5 | two-author bylines; a sentence starting with "Von" |
 Every rule *re-types* (not narrated/used, still visible, reversible in the UI) and is idempotent, runs on import and on
 re-OCR, writes a timestamped backup first. Overlapping boxes with different text are **surfaced for a human, not
 auto-fixed** — we generate a review list with a suggested action per pair.
 ### 7. Reading order (only if your documents have columns)
 Sorting by y interleaves parallel columns. What worked: columns come from where column-width blocks *start*
 (clustered left edges), not from whitespace between columns (OCR boxes are loose; a 2 pt gutter and a pull quote across
 it defeated the whitespace method); measure column width on body text only; bands — a headline/standfirst spanning
 columns in a strip of its own is read first; **never** use paragraph gaps as breaks (they line up across columns and
 re-interleave them: tried, measured, reverted). Measured with a text-only score (a block ending mid-sentence must be
 followed by its continuation; a split word by its other half) over 204 pages: confirmed continuations 85 → 89.
 Let users lock a hand-ordered page (`order_locked`) so no recompute overwrites it.
 ### 8. Running furniture (headers, footers, page numbers)
 Identify by **repetition**, not position (a running head and a headline both sit at the top). Exact-match repetition
 fails once OCR is involved (`c't Wissen 2026` came back as `cE KI-WISSEN`, `ce Wissen 2136`, …), so add a fuzzy pass:
 near-edge blocks, digits stripped, `SequenceMatcher` ≥ 0.6, ≥ 3 occurrences. Without it one scan produced 26 bogus
 "articles" from footers. An engine that labels footers directly makes this unnecessary for its pages.
 ### 9. A whole-document quality pass that reports, and fixes only what is provable
 Per page, read-only audit from the render: `uncovered` ink blobs outside every box (ignore page-edge margins ~3%,
 dust < 10 cells, rules and dotted leaders < 6 ink rows, unboxed ink within 10 pt of a picture); `overlaps` (text boxes
 sharing ≥ 30% of the smaller); `clipped` edges (ink in a 14 px strip just outside a box's side, ignoring what another
 box covers, ignoring strips that are pictures — ink density > 0.7); `suspect_blocks`. Independent completeness check:
 run local OCR as a second opinion over the page (`recover_missing_text`) and *add* missing text as new **unticked**
 regions, never replace boxes. Re-read dictionary-suspicious regions with the image engine and accept **only** a
 better reading (`verify_ocr_recognition`). Spelling: findings, not rewrites — a model may propose a fix only if it is a
 dictionary suggestion or a single known word within two edits, offsets re-verified against the current text.
 Run the whole thing automatically as the last import step under the same progress job; report failures instead of
 hiding them.
 ### 10. Human review is part of the design, and the UI must make errors visible
 Nothing downstream (audio, export, search) uses unreviewed text. Review screen essentials, all of which paid off:
 region boxes drawn on the page image, colour-coded by type with a legend; numbered in reading order; per-region type
 picker, delete, merge-with-next, split-at-cursor, per-region re-OCR, inline text edit; keyboard navigation; bulk actions
 with **undo instead of confirmation dialogs** (one level, tokenised, sealed with a digest so a stale Undo can never roll
 back newer work); draw-a-missed-region; two-page spread; a live ingest preview that draws boxes as they are found
 (purely decorative — progress numbers live in a separate status line for screen readers). WCAG 2.2 AA: icon + text,
 never colour alone; labelled controls; keyboard alternative for every drag; reduced-motion respected.
 ## Engineering rules that kept this maintainable
 - **Pure logic in one module, I/O at the edges.** Geometry/classification takes plain data, so tests need no PDF,
  no engine, no network. Import PyMuPDF lazily. Mock HTTP for engine tests.
 - **Constants are named and commented with the measurement that set them** (`_SNAP_SOLID = 0.55 # ...`). When you
  change one, re-measure.
 - **Every destructive action writes a backup or undo point first;** writes are atomic; jobs are restart-safe and a
  "running" state whose job died is reported as failed, not spun forever.
 - **Idempotence is a feature:** re-running any fix on an already-fixed document changes nothing.
 - **Per-document data stays out of git** (copyrighted/private pages, quality reports quoting text).
 - **Security at the boundary:** validate ids (server-generated hex only), bound upload/download sizes, timeouts on
  every engine call, no credentials in URLs or logs.
 - **Test both directions:** for each heuristic add a test for the case it fixes *and* the case it must leave alone
  (the "left alone on purpose" column above came from failing tests, not foresight).
 ## Order of work I recommend
 1. Benchmark + baseline of the current engine(s) (Step 0). Report the numbers before changing anything.
 2. Cheap, high-yield robustness: per-page escalation, fallback ladder, repetition-loop and refusal filters, engine
   labels trusted, plausibility score.
 3. Box quality: fit text boxes to ink, figure bounds from the render, clean-up rules — each sized on real data first.
 4. Audit + review list (overlaps for humans), then the review UI improvements that fit this app.
 5. Reading order / furniture / articles — only if this app's documents have that structure.
 6. Re-benchmark; report before/after with the same metrics, and list what did **not** help.
 ## Deliverables
 - A short plan classifying each item above (applies / does not apply / needs decision), with expected effort.
 - Benchmark script + results (metrics only) + README in the repo.
 - Each adopted item: implementation, unit tests (positive and negative), docs/manual/changelog updated, one commit.
 - A final before/after table and an honest list of limitations.
 ## What not to do
 - Do not add a heavy OCR/vision engine because it is fashionable; our measurements found no accuracy gain over
  tesseract on clean pages and a 4–20× speed cost. Prove the gain on *this* app's documents.
 - Do not auto-delete or auto-merge overlapping boxes with different text.
 - Do not let a model's output edit text unless a deterministic check confirms the edit.
 - Do not trust the engine's bounding boxes for graphics.
 - Do not run installs of multi-GB models on a machine without checking free memory first (GPU and system memory can
  be one pool; a kill can take down unrelated services).

 `GET /health` → `{"status":"ok","device":"cuda (NVIDIA GB10)","version":"0.5.6"}`.
 Nothing here was integrated or installed by this session; the running instance was probed
 read-only (`/health`, a handful of 401-gated paths) and nothing was written to it.
 ## What it is
 An open-source, **general-purpose local speech platform**: voice cloning, voice design (text
 → voice), video dubbing, a floating dictation widget, transcription, and batch/audiobook
 jobs, in 646 languages via pluggable engines. Primary distribution is an **Electron desktop
 app**; the same backend also runs headless (Docker) with a web UI, a local REST/WS API, and
 an **MCP server** for agents. Default TTS engine is k2-fsa/OmniVoice; 15+ other engines
 (CosyVoice 3, IndexTTS 2.5, VoxCPM2, sherpa-onnx, gpt-sovits, …) are selectable per install.
 - **License:** AGPL-3.0-only. Commercial use of the app itself is explicitly allowed; the
  *Affero* clause only bites if a **modified** version is offered to others over a network
  (then its source must be offered too). A commercial license to drop that obligation is
  sold separately. Model weights carry their own, separate licenses — check before
  commercial use of a specific model. **Not a concern for this evaluation**: nothing was
  embedded or modified; it matters only if this project ever vendors VoiceStudio's own code.
 - **Maturity:** created 2026-04-09, 3,470+ commits, pushed today, 46.2k stars / 5.2k forks /
  59 open issues (via the GitHub API — not the fetch tool's summary, which is untrusted third-
  party text). Very actively developed; CI, benchmarks, an engine-acceptance bar, and a
  performance guide with numbered postmortems (e.g. issue #1032) all point to a mature
  release process, not a weekend project.
 - **Privacy:** local-first; optional remote workers; "usage analytics requires consent" per
  the README, though the served page's CSP allow-lists PostHog endpoints (`*.i.posthog.com`)
  — worth checking that consent gate before pointing anyone but the household at it.
 - **Install:** one-line installer script, signed release downloads, or Docker
  (`ghcr.io/debpalash/voicestudio`, **linux/amd64 only** — matters for an ARM host, not for
  the DGX Spark, which is amd64).

 ## Where VoiceStudio is clearly ahead
 - **Engine breadth.** Swapping TTS/ASR backends per install/hardware is a real, mature
  feature here; this app is hard-wired to Qwen3-TTS.
 - **Dictation and dubbing** are first-class features this app has no equivalent of.
 - **Multi-language transcription** (646 languages, diarization) goes well beyond this app's
  Whisper-via-conversation use.
 - **Documentation discipline**: a performance guide with numbered issue postmortems, an
  explicit engine-acceptance bar, and measured benchmarks are a level of process rigor worth
  borrowing for this project's own `Manual.md`/`architecture/` habit, independent of the code.
 ## Where this app is clearly ahead
 - **The entire magazine pipeline** — nothing in VoiceStudio's feature list touches PDF
  ingestion, OCR-driven layout, box review, spelling/acronym correction, or linking a
  continuing article across pages/columns. That is this project's actual differentiator and
  the reason for the last several weeks of work; VoiceStudio does not compete with it.
 - **Purpose-built review UI** for a specific workflow (audiobook production from print),
  versus VoiceStudio's general creation/dubbing workspaces.
 ## Practical risk: they share the GPU
 Both now run on the same DGX Spark (GB10), confirmed live (`/health` reports
 `"device":"cuda (NVIDIA GB10)"` — the same GPU this app's Qwen3-TTS/vision-OCR/LLM calls
 compete for). A heavy VoiceStudio job (a long dub, a big batch) and a magazine's vision-OCR
 Auto-fix pass run at the same time will contend for VRAM and compute; if VoiceStudio stays in
 use, keep an eye on `nvidia-smi` during a large Auto-fix run rather than assuming isolation.
 ## Recommendation
 Not a replacement candidate for this app — the two solve different problems and the
 magazine pipeline has no counterpart to compare against. Worth revisiting narrowly:
 1. **As an alternate TTS backend for narration quality**, if Qwen3-TTS output on a
   difficult voice/language ever needs a second opinion — IndexTTS 2.5 or CosyVoice 3 are
   the more actively recommended engines in VoiceStudio's own catalog.
 2. **Its MCP server** is a quick way to compare a given sentence's narration across engines
   without wiring a new backend into this app first.
 No integration was started; this is an evaluation record only, per the TODO item.
 ## UI/UX and feature-parity deep dive — 2026-09-29
 **Methodology, stated plainly:** no browser was available to render either live UI this
 session (no Chromium binary for Puppeteer, no connected DevTools extension). VoiceStudio's
 screens below are its **own published screenshots**, fetched from its repo
 (`docs/media/electron/*.png`) and viewed directly — real product screenshots, not a live
 session. This app's side is grounded in its actual served navigation
 (`curl https://voice.martin-bierschenk.de/`, parsed for `data-nav-section`) and this
 session's own knowledge of its routes/templates — not a rendered screenshot. Anything below
 attributed to "this app" is checked against a file or route; anything about VoiceStudio's
 *screens* is what its own screenshot shows, not a guess.
 ### VoiceStudio's screens (from its repo)
 - **Voice cloning** (`voice-cloning.png`): left sidebar (Voice → Clone/Design/Saved/Gallery,
  Stories, Dubbing, Transcribe, Projects, Tools, Integrations), a script editor with
  import/paste/insert, a bottom dock of **third-party integrations already wired into the
  chrome itself** (Twilio, Plivo, Telnyx, n8n, Zapier, Make, GitHub, GitHub Container
  Registry, Docker, …), and a top-right **global search / command palette** and "Recent
  takes" history spanning the whole app, not one workspace.
 - **Voice design** (`voice-design.png`): a free-text description box, but also a **curated
  gallery of named starting-point personas** ("The Librarian", "The Anchor", "Captain
  Crusty", …) each with a one-line pitch, a play button for a real demo clip, and
  "Use this design →". Plus quick descriptor tags (Narrator/Casual/News Anchor/Storyteller/
  Corporate/Energetic/Whisper/…) and a "Details" editor (age, pitch).
 - **Video dubbing** (`dubbing.png`): upload/paste a YouTube URL → transcribe → pick target
  language + dialect + translator (an **offline NLLB-200 (Local, Heavy)** option is offered
  right next to "Translate with AI") → timing/production overrides → generate. A synced
  side-by-side waveform player plays the **original and dubbed audio together**, with a
  language switcher to preview other dubs of the same demo before running your own file.
 - **Model management** (`models.png`): one-click **model-pack tiers** (Fast/Balanced/
  Quality/Max) that bundle a whole TTS+ASR+dictation+translation stack with the disk size
  shown before you commit ("8.5 GB installed size"), per-category model pickers (TTS/ASR/
  Dictation/Diarisation/Translation/LLM), a voice-preview pre-rendering toggle, an explicit
  compute-device picker, and a Hugging Face mirror selector. The Settings sidebar alone has
  19 sections (General, Appearance, Models, Pronunciation dictionary, Updates, Network,
  Sharing & Remote Access, Credentials, Compute device, Usage, Remote workers, Privacy,
  Permissions, Storage, Support, …).
 ### This app's screens (from its served nav and routes)
 Sidebar: **Voices** (Clone a Voice / Design a Voice / Get a Voice Online), **Quick Play**,
 **Conversation**, **Cast Studio**, **Reader** (audiobook), **Magazine**, **Rehearser**,
 **Library**, **Benchmark**, **Engines** (LLM routing), **App Routing**, **Connect Apps**,
 **Settings**. Settings itself has 4 pages (General, Payloads, Storage, API keys) — thin
 next to VoiceStudio's 19. "Connect Apps" is a real counterpart to VoiceStudio's integration
 dock, just aimed at a different audience: ready-made snippets for SillyTavern, Open WebUI,
 Home Assistant, Claude Code MCP, a raw `/speak` REST call, and a **global hotkey daemon** —
 AI-tooling integrations rather than VoiceStudio's telephony/business-automation set
 (Twilio, Plivo, Telnyx, Zapier, Make). Voice Design already has save/load/delete named
 presets (`design-preset-*`), just as a plain dropdown, not a curated gallery with demo audio.
 ### Features VoiceStudio has that this app doesn't (real gaps, not nitpicks)
 1. **Video dubbing end to end** — upload/URL → transcribe → translate (with an offline
   model option) → re-synthesize timed to the original. This app has nothing upstream of
   TTS for video at all.
 2. **Live STT dictation into any focused app** (its Rust sidecar + floating widget). This
   app's "hotkey daemon" triggers *playback* of a voice, not speech-to-text insertion — a
   different feature wearing a similar name; do not conflate the two.
 3. **Telephony integrations** (Twilio, Plivo, Telnyx) for inbound/outbound call voice —
   this app's integration list is chat/automation tools, not telephony.
 4. **Standalone offline translation** (NLLB-200 as a first-class, selectable model) — this
   app has no translation step anywhere in its pipeline.
 5. **Model-pack tiers and an explicit compute-device picker in the UI** — this app's engine
   endpoints (Qwen3-TTS, vision OCR, the LLM) are configured as URLs in Settings/Payloads,
   not chosen from an in-app catalog with disk-size and device shown up front.
 6. **A global command palette / search and cross-app "recent takes" history** — this app's
   history (undo/redo, generation history) is per-feature (e.g. the magazine's own 20-step
   undo stack), not a single cross-app view.
 7. **A curated voice-design preset gallery with demo audio** — a real UX idea worth
   borrowing even without adopting anything else: a handful of named, demo-backed starting
   points lower the bar for someone who doesn't know how to word a voice description, versus
   this app's blank textarea plus a plain preset dropdown.
 ### Where this app is ahead that VoiceStudio's screens don't show
 Confirms the earlier verdict: the **entire magazine pipeline**, **Cast Studio**/character
 casting, the **Rehearser**, and the **Reader**'s audiobook-specific workflow have no
 counterpart anywhere in VoiceStudio's four screens or its feature catalog — it has no
 document ingestion, no per-article review, and no multi-character casting concept at all.
 ### What is worth actually adopting here
 Two low-risk, high-value ideas, independent of any VoiceStudio integration:
 - **A curated voice-design preset gallery** (a handful of named personas with a demo clip
  and one-click "use this design") in `s-design.html` — the single most transferable idea
  above, since this app already has the preset save/load machinery to hang it on.
 - **An explicit compute-device indicator** somewhere in Settings, mirroring VoiceStudio's —
  cheap to add (query the backend once) and answers "is this actually using the GPU?"
  without opening a shell, a question this app's Settings currently has no answer to at all.
 Video dubbing, telephony integrations, and a full model-pack catalog are real gaps but not
 small asks — each is its own multi-day feature, not a quick addition, and none of them
 serve the magazine/audiobook workflow this app is actually for. They belong on a future
 roadmap decision, not this evaluation.

 """Legitimate places to find a magazine issue to import: OPDS catalogues and the Internet Archive.

Identifies real gaps (video dubbing, live dictation, telephony integrations, offline translation, model-pack UI, command palette, a curated voice-design preset gallery) and two low-risk ideas worth adopting (preset gallery, compute-device indicator).

mARTin-B78	faa3c16a91	fix(magazine): exclude advertisement pages from magazine-comparison statistics A page either side marks as a full-page ad is skipped by that side's quality run, so comparing its near-empty boxes against the same page freshly OCR'd on the other side (ad-marking is a one-time manual step) was a review-state difference, not a pipeline one, skewing whole-issue numbers. Verified: text similarity 0.837->0.870, box precision 0.62->0.66 on the real re-import. Also records the clean from-scratch re-ingest results: the ingest-time duplicate-check ordering fix is proven in isolation (0 additional duplicates found afterward, vs 13 before the fix), and the auto-chained Auto-fix ran end to end. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>	2026-09-29 13:11:00 +02:00
mARTin-B78	f0b5d5aa68	feat(magazine): run the whole-issue Auto-fix pass automatically after import A fresh import used to stop once laid out, leaving missed text, unverified OCR and provable misspellings for a separate manual click. _ingest_sync now runs _quality_run_sync itself, under the same job, so the ingest progress bar carries through it and the reviewer opens an already-worked magazine. An Auto-fix failure is reported as an ingest failure without losing the ingest's own result. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>	2026-09-29 09:37:28 +02:00

mARTin-B78	ac1153b782	fix(magazine): re-check for duplicate boxes after box-fitting/seam-mending grows them The duplicate detector only ran once, before geometry fixes could merge or grow a box into one that now duplicates another's text -- narrating it twice. Now re-run after the geometry loop at ingest and after recover_missing_text in the whole-issue quality run. Confirmed live: 13 such duplicates in a fresh import, 6 in the already-reviewed magazine. TODO: F decided unnecessary per user; G updated with both universal fixes from this pass. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>	2026-09-29 08:50:13 +02:00
