Magazine P1:
- Images shown automatically during playback (assign_images_to_articles
links each figure to the article whose column it falls in; the client
shows the last image reached in reading order as playback advances).
- "Play all articles" queues every approved article and advances
automatically at the end of each rather than stopping.
- Word-level highlighting, explicitly documented as an ESTIMATE (no
forced-alignment/timestamp source exists): each word's share of the
sentence's real measured audio duration is proportional to its
character length. A checkbox turns it off; sentence highlighting
(measured, not estimated) is unaffected.
- Driving mode: full-screen overlay, two oversized controls, reuses
whatever is already playing/queued.
- Sidebars/pull-out boxes excluded from narration automatically
(mark_sidebars: an anomalously narrow column vs. the page's regular
grid). Fixed a real defect found while building this: a full-width
headline was left in the column-width analysis and could bridge two
genuinely separate columns into one, hiding a real sidebar column
entirely -- caught by a failing test before the fix.
Second OCR engine + fallback ladder:
- KDL Frontier Parser nano wired in via vision_ocr_page_chain (ordered
engine list, first usable result wins, tesseract last resort).
Confirmed live: ~3x faster than Baidu (~12s vs ~40s/page) but returns
plain text with NO coordinate markers, unlike Baidu's labeled regions.
_whole_page_region treats the whole response as one ambiguous
full-page block (gated by ocr_quality_score) rather than discarding
usable text just because it lacks layout structure.
OCR engines page + a real UI bug:
- The OCR & Document Parsing page had no .s-engines-page[data-page="ocr"]
markup at all -- renderLocalContainers already supported an OCR grid
generically, but $('dc-grid-ocr') was always null, so the card grid
silently never rendered. Added an Active OCR Engine panel mirroring
Active Language Model exactly, plus the Local grid -- both configured
engines now appear as ready-made cards, no "Add Custom" dialog needed.
- Fixed the audiobook pipeline's "Previous/Next" nav bar bleeding into
every .section-head in the document (confirmed live on the Engines
page: a "Cast Audiobook" button and "STEP 1/8" hint that made no sense
there). Changed from a blocklist (naming each unrelated section as
noticed) to an allowlist of the pipeline's three actual destinations.
Verified live end-to-end: play-all queue building and manual advance,
word-span markup, driving-mode toggle, OCR page showing both engines as
local cards, zero stray nav bars on the Engines page, no console errors.
20 new backend tests (156 total in the magazine module).

Studio -> Magazines: library, contents tree grouped by section with
confidence/pages/listening-time/audio status, the Stage D review
screen (tick/untick layout blocks, correct title/author, approve or
reject), a reflowed article view with click-to-seek sentence
highlighting, a linked original-page view showing the source bounding
box, and a podcast panel (2-3 host pickers, script generation,
turn-by-turn playback).
Wired into the existing lazy-module system (module-manifest.json,
loader.js, nav.js) rather than a separate app. Reuses /api/tts-preview
for both narration and podcast turns -- no new audio pipeline.
Fixes found building this:
- The pane toggle used role="tab" without the full ARIA tabs pattern
(aria-selected, roving tabindex, arrow-key nav) -- fails WCAG 2.2 AA
and hid the buttons from role-based tooling. Replaced with a button
group + aria-pressed, matching the plain-click interaction it
actually has.
- Print layout cues ("(continued on page 8)") were being sent to TTS
verbatim -- narration would have spoken the parenthetical aloud.
Stripped from the narration copy only; layout.json keeps the
original for the review screen.
- has_podcast now comes from the articles listing so opening an
article without a generated script skips a doomed GET instead of a
routine 404 on every open.
Verified against the real API contract with Playwright (library,
review pre-selection, approval, sentence highlighting + PDF-page
linking, podcast approval gate, zero console errors across the flow)
and manually end-to-end against a real ingested fixture, screenshots
included. Full suite: 94 Python tests, 33/34 desktop Playwright tests
(one unrelated pre-existing flaky DOM-count assertion).

- Deterministic hash-based character portraits and reference sheets
- Implemented strict early Renaissance aesthetic controls and role-specific headwear rules
- Added audiobook batch export scripts and progress tooling
- Verified book profiles with a new 'confirmed' state tracking mechanism
- Updated Pillow dependency for robust image handling
- Configured .gitignore for audiobook and audio cache exports
Fish-Speech clones from the app's own saved WAV library but was missing from
the set of backends populated with those voices, so the UI probed the Fish
server for a voice-listing endpoint it does not have, showed "Fetched 0
voices" and left the engine unusable despite being healthy. It now reports
the full library (218 voices).
Also adds a Fish-only panel listing all 49 documented emotion tags with
click-to-insert and a multi-emotion example, and corrects the backend's
advertised capabilities: it was flagged style_aware with "emotion markers are
honoured per request", but measurement shows a reference clip's in-context
prosody overwhelms inline tags (10x loudness spread across emotions without a
reference, 1.2x with one). It is now described by what it does well:
deterministic, byte-reproducible cloning.

Fish-Speech emotion tags were silently ignored on non-English books: per-line
emotions are LLM-generated in the book's own language, but Fish-Speech only
recognizes English [tag] markers, and a double-tagging bug was stacking a
broken server-derived tag on top of the client's own. Added a DE->EN
translation table and removed the double-tagging. Also wires the existing
book-profile context and race_species field into character portrait prompts
(previously only used for voice design), adds a recast-until-threshold loop
for casting, and adds backend-aware emotion quick-picks to Read Aloud, Try a
Voice, and Conversation.

Voice consistency:
- Read back each voice's pinned seed (Seed Finder / Batch Seeds) on every
generation. The seed was saved to voice metadata but only ever read by the
Seed Finder's own benchmark path, so all per-voice seed pinning was inert.
- Stop coercing the "voice_design_playback" stability profile back to
"voice_clone". The pseudo-backend key isn't a real routing target, so the
backend-name normalizer silently rewrote it — reintroducing the hardcoded
seed:0 that profile exists to avoid, overriding every per-voice pin.
- Apply the accent clause on every line, not just at voice-creation time,
and reorder the instruct so emotion leads and accent trails (Qwen3-TTS
doesn't reliably follow multiple conflicting instructions).
- Pass an explicit language to Voice Design instead of leaving it on "Auto".
Audio effects:
- Add a limiter after compressor makeup gain. Makeup gain pushed peaks to
~1.9, and the final hard clip turned that into broadband distortion that
swamped the rest of the chain.
- Cascade highpass/lowpass 3 stages each (~18 dB/octave). Single-pole
filters were too gentle to band-limit speech audibly.
- Add a Bandpass control and wire it into the Telephone/Radio presets —
compression alone never sounded like a phone; band-limiting is the
defining trait.
Persona / Try It Out:
- Disable "Apply character persona" with an explanatory tooltip when the
voice has no persona saved, and error clearly server-side instead of
silently no-op'ing. Persona is typed manually per voice, never auto-filled.
- Stop dropping applyPersona in the chunked generation path (>200 chars).
- Populate the Voice Design dropdown from the user's own library rather than
filtering the engine's discovery list, which never contains custom voices.
Navigation and library:
- Use pushState instead of replaceState so browser Back/Forward step through
in-app navigation instead of leaving the app entirely.
- Show real dialogue line counts in the character sidebar instead of the
capped reference-quote count (which showed a misleading uniform "12").
Also fixes a crash in /api/transcribe-bytes that referenced an undefined
source_id in its cleanup path.

Introduces the new Studio section (Source -> Characters -> Voices ->
Perform & Export) that reuses the existing Read Aloud/Library/Script
Rehearsal code via DOM reparenting instead of duplicating it, and rolls up
a long tail of bugs found while producing a real audiobook through it:
umlaut-eating name sanitizers, a voice picker that mispositioned itself and
capped results at 60, PDF pagination silently breaking on trimmed \f
markers, a race letting stale audio keep playing after a new line was
clicked, an alias-overlap bug that could silently redirect a voice/image
save onto the wrong character, voice design failing outright during brief
TTS backend restarts instead of retrying, sparse cast entries defaulting to
English/wrong gender, and a reassigned voice never reaching an already-open
Stage session or invalidating its cached audio. Also adds a persistent
per-line audio cache, audiobook export browsing/download, and an inline
voice-design prompt editor. Full details in CHANGELOG.md.

Reasoning-model chain-of-thought is now separated from the spoken/displayed
reply on the server (handles both a dedicated reasoning_content field and
inline <think> blocks, including chat templates that inject the opening tag
as a prompt prefix so it never appears in the stream). The client shows it
in a panel collapsed behind a "Thinking" chevron instead of dumping raw
reasoning text into the chat or speaking it aloud via TTS.
Also moved the noise-gate slider out of its own row and next to the mic
button, grouping it with Auto-stop/Hands-free/Live agent.

Two unclosed <div class="card"> tags in the TTS settings markup left the
add-engine dialog nested inside the TTS panel's DOM subtree, so it
rendered at zero size whenever another Engines sub-tab (e.g. Speech
Recognition) was active. Also fixed a `let` declared after its first
use, which threw a ReferenceError on every Engines-tab page load.

- App Routing's output-voice field gets the same searchable
avatar-thumbnail dropdown used elsewhere, as a browse button
alongside the existing free-text input (which must stay editable to
target vd_ Voice Design presets not in the voice library).
- My Voices table: Gender and Rating filter dropdowns existed in the
JS (populateLibraryFilters, libraryFilterMatch) but their <select>
elements had been dropped from the visible layout after an earlier
redesign, replaced with hidden dead placeholders just to keep the
code from erroring - and since populateLibraryFilters() early-returns
if any of the three elements are missing, this silently broke the
already-visible Language/Type dropdowns too. Restored the real
elements and removed the hidden scaffold; added new Tag and Group
dropdowns wired to the same filter state the sidebar chips use.
- Audio effects failing with "pedalboard is not installed" despite
requirements.txt listing it: the package WAS installed, but its
native extension (pedalboard_native) links against libatomic.so.1,
an OS-level shared library missing from the python:3.11-slim-bookworm
base image. Added libatomic1 to the Dockerfile and rebuilt - verified
`import pedalboard` now succeeds in the running container.
- Relabeled "edit ID"/"copy ID" to "rename filename"/"copy filename"
in the voice inspector - the feature already renamed the underlying
.wav/.meta.json/.reference.txt/picture files via the existing
/api/voice/rename endpoint, it just wasn't obvious "ID" meant
"filename."

Character sheet generation is already available from "Cast Characters"
in the Casting flow, so the standalone button here was a duplicate
entry point. Removed it and made "Cast as audiobook" the primary blue
action, moved to the end of the toolbar as the clear next step in the
pipeline.

Replaces the horizontal avatar strip above the transport bar with a
sidebar next to the script page, reusing Read Aloud's Casting sidebar
classes (.ab-cv-side/.ab-char-item) directly instead of a separate
look. Same collapse-to-avatars control, now shows each character's
line count, and clicking a character scrolls the script to their
first line. Removed the CSS/HTML this replaces.

Characters/Cast gains a "Casting" button back to the active casting
session, the pipeline stepper renders on the Library section, and the
stepper's Cast Characters stop navigates instead of side-effect-running
sheet generation. Prompt generation: 4096-token budget (1600 truncated
the four-prompt JSON so two fields silently arrived empty), truncated
answers salvage completed fields, all-empty responses fail loudly, and
partial results name the missing prompts. The PDF-extraction progress
pill is enlarged and vertically centered.

Speed: OCR renders only the heading band (was full page at 2.5x),
Tesseract worker freed after extraction, name-underline index cached
instead of rebuilt per segment, constant regexes hoisted, old drafts
migrate segment page numbers once at load (single-path feed renderer).
Quality: global [hidden]{display:none!important} ends the empty-box bug
class; racy deferred cast-restore + _readerSuppressCastRestore flag
replaced by a synchronous, caller-wins restore; card collapse defaults
move to data-collapse-default markup; duplicated join/colour/alias/LLM-
target helpers now delegate to their canonical implementations; dead
reader state removed; stepper hide-guard fixed for the merged Source key.

- Add a 6-stage pipeline stepper (Source -> Cast Audiobook -> Cast Characters
-> Script Rehearser -> Generate MP3s -> Audiobook) with direct, non-destructive
jumps between stages and a prominent guided-tour look
- Split PDF import into an explicit "load" then "Extract Text" step, with
in-browser OCR (Tesseract.js, vendored) to recover chapter headlines baked
into a PDF as images instead of real text
- Fix casting feed silently merging pages after leaving/returning: segments
now carry their own page number instead of re-guessing it from text
- Fix excessive "Unknown" speaker attribution: restore the attribution LLM's
output token budget, which had been cut roughly in half and was truncating
dialogue-dense passages
- Fix Theater Play library cards failing to open (dead pre-migration
IndexedDB API calls, missing section navigation)
- Fix bulk "Set tag" wiping a voice's existing tags instead of adding to them
- Start merging Casting's feed with Script Rehearser's Stage UI: collapsible
character sidebar, shared "paper" page styling, inline text editing
- Fix a performance regression from that merge (per-row listeners on every
redraw) by moving to event delegation
- Various layout/clutter fixes: hide reader chrome until a document is
loaded, collapse secondary settings by default, fix overlapping toolbar
icons, fix duplicate "opening" notifications

Root cause 1 (v1.12.18): `window.loadVoiceLibrary = () => loadVoiceLibrary()`
overwrites the global binding the arrow function references, causing immediate
RangeError: Maximum call stack size exceeded on every call. Changed to direct
assignment `window.loadVoiceLibrary = loadVoiceLibrary`.
Root cause 2 (v1.12.18): `loadSettings()` called `renderSettingsAbout()` which
lives in conversation.js (batch E), loaded after init.js. Guard added with
typeof check; nav.js already calls it safely when the About section opens.
Also (v1.12.18): s-library.html duplicated cl-book-filter / cl-search / cl-grid
from s-characters.html, breaking getElementById. Characters panel in Library
now redirects to s-characters instead of duplicating its DOM nodes.
Also (v1.12.19): engines.js triggers a second loadVoiceLibrary() after nav.js
already rendered voices, blanking the list briefly. Second call now silently
re-fetches without clearing the list when voices are already present.

Voice selection list now shows flag + gender symbol on each row.
Batch results table adds Lang and Gender columns. All columns are
sortable by clicking the header (↑↓ indicator); defaults to Factor
descending. Sort logic handles strings (locale) and numbers uniformly.

Voices table: removed Length, Duration, Time — only Factor and WPM remain
from benchmark data. Setup → Benchmark batch results now shows Duration,
Factor (sorted fastest-first, colour-coded), Time, and WPM. Factor replaces
Avg RTF with the same data flipped to a more intuitive direction (higher=better).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The old combined `21.8s · 1.30x` Speed cell is replaced by two separate
sortable columns:
- Factor (x.xx): audio÷render multiplier, green/amber/red colour-coded
- Time (Xs): total render time
Column order: Length · Duration · Factor · Time · WPM · Seed · dBFS · ...
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
WPM (words per minute) is derived from the benchmark audio duration and
sentence word count, revealing how fast a voice speaks — independent of
GPU speed. 130–180 wpm is comfortable for audiobooks. Column is sortable.
Info (ⓘ) icons on Speed and WPM headers explain both metrics on hover.

- Add Source input to voice inspector panel (saves to origin in meta.json)
- Auto-detect fish-audio voices via tag — SOURCE column now shows
"fish-audio" for tagged voices even without an explicit origin field
- Bulk "Set source" action in the multi-select toolbar
- Source cell in table reflects the live-displayed value and updates
immediately when changed via the inspector
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Conversation: adjustable noise gate slider (RMS threshold + 300 ms
minimum burst duration) prevents short noise spikes from triggering
STT; level meter shows gate position as a blue marker
- Conversation stats panel now collapsible (chevron button) to free
chat width; floating expand button restores it; state persists
- Read Aloud: text search input in PDF toolbar (Enter = next hit,
Shift+Enter = previous, Esc = clear)
- Sidebar: tooltip now works for all item types including sub-items
that had no .nav-label span (text extracted by stripping icon/badge)
- Sidebar active section indicator added (.nav-tree-item.active was
previously unstyled — active section now has bg + right accent bar)
- Casting audiobook: prompt instructs LLM to handle ?« / !« endings
and unclosed » at passage end as dialogue; deterministic fallback
also handles unclosed opening quote
Bumps to v1.12.2.

- Sidebar collapses to a 56px icon rail; hovering flies the full menu out as
an overlay (icons + titles/nested items). Language picker moved to Settings.
- Unify settings collapsibles to the app's standard card-collapse style:
Conversation, Read Aloud (drag-&-drop now inside), Try It Out, Casting panel.
- Read Aloud: reordered (settings → toolbar → document → transport/synth) and
the document fits the viewport height so controls below stay visible; remove
the redundant My Books card (lives in Library → Books).
- Conversation: stacked full-width config, fills viewport height; fix
intermittent webm decode in hands-free mode (recorder restarts cleanly,
in-browser WAV encode); barge-in via Live agent.
- Fix casting feed overflow that pushed the sidebar off-screen.

Restructure the sidebar into Voices / Speak / Setup groups and fuse the
Read Aloud and Script Rehearser features into one workspace:
- New combined Library section (Books · Theater Plays · Characters/Cast)
with cross-links (Rehearse a book, Read Aloud a play).
- Character tags like voice tags: one record, many productions, reusable
across books/scripts; seeded with origin book, editable in the editor.
- Shared cast resolution: opening a production fills empty cast slots from
the character roster (matched by book OR tag); voice choices written back
on save. Productions joined by normalized title (prodKey).
- Tags nav group for voices (distinct tags + counts, Cloned/Designed/Fav).
- Fold standalone Characters into Library; Read Aloud now a single entry.

Exposes the `speed` parameter (0.5–2.0) on the TTS `/v1/audio/speech`
request so audio is generated at the target tempo natively via the
faster-qwen3-tts backend rather than post-processing.
- Backend: `/api/tts-preview` now extracts and forwards a `speed`
override (clamped 0.1–4.0) through the same extra-params mechanism
already used for seed/temperature; backends that reject it fall back
cleanly via `_post_tts_with_fallback`.
- Try it out: "Native Speed" number input (0.5–2, step 0.05) added to
the text card; value persists in localStorage per browser; passed as
`extra` through `createTtsAudioSource` and `generateChunkedTts`.
- Read aloud: "Native Speed" control added to the generation controls
row alongside seed/temperature; included in `readerGenParams()` and
saved/restored with library documents (each book tracks its own speed).

- Character sheets: stop sending the dead localhost:11434 default; fall back to
the server's configured llm_url so extraction uses the same working LLM.
- Audiobook casting: hoist highlightText to module scope so the "Review & cast"
manual-correction preview renders its segment rows again.
- Stage: unify narrator/dialog font size, add A-/A+ play text-size control
(scales A4 + paginated views), and make the cast chip list collapsible.

Add a persistent, book-scoped Character Library (new Characters section,
IndexedDB) that auto-fills from Character-sheet analysis with editable cards.
Enrich extraction with six narrative fields (backstory, relationships,
motivation, fears, mannerisms, voice/speech) plus the greyscale Good↔Evil
alignment bar, arc arrow, and 5-area Deep Analysis. Add ⋯ separators between
non-contiguous passages in Recast unknown, and harden dialogue attribution
against hallucination with same-language emotion tags.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- Added a new 'Table View' button to the library sort bar.
- Implemented a CSS grid layout to display voice properties in a high-density table.
- Added sortable column headers (Name, Lang, Gender, Speed, dBFS, Length, Rating, Source, Seed, Note, Tags, Active).
- Aligned CSS grid to account for the bulk edit checkbox injection.
- Added drag-and-drop profile image support to the Inspector's large avatar.
- Ensured picture updates instantly synchronize across the List, Table, and Inspector views.
Read Aloud (new "Vorlesen" tab):
- PDF (real page render + overlay highlight) / TXT reader with live word
highlighting, voice + speed, per-sentence synthesis-state colours, zoom
(fit-width/height, two-page, ±), resume, and a server-side book library
(syncs across devices; per-unit MP3 audio fetched on demand).
Book -> multi-speaker audiobook:
- "Cast as audiobook" attributes dialogue to characters via the LLM
(guillemet/quote-style aware, turn-taking, recent-context), with a
deterministic speech-tag fallback. Editable preview, non-blocking live
casting panel, then auto-saved as a reopenable Script Rehearser play.
- Audiobook export: synthesise every cast line -> one MP3 per chapter.
Character sheets:
- LLM-extracted, self-filling RPG-style sheets (with page+quote sources)
in both Read Aloud and the Rehearser.
Also: MP3 storage + per-page/sentence export, voice-library "Precompute
embeddings" pre-warm, German "Vorlesen" i18n + flag language toggle,
large-PDF performance (lazy raster, buffer/canvas eviction, yielded parse),
and the Seed Finder changelog entry.
New: routes/reader.py, POST /api/attribute-dialogue, POST /api/character-sheets,
static/js/{reader,audiobook,character-sheets}.js, static/sections/s-reader.html.
