The streaming attribution endpoint decoded the LLM's SSE response with
requests' guessed encoding (Latin-1 fallback when no charset is declared),
mangling every German umlaut. Forced UTF-8 explicitly.
The "LLM Thinking" pane duplicated the passage text for models that
ignore the <think> instruction and stream straight into JSON - it now
only shows real reasoning when present, and otherwise labels raw output
honestly instead of passing it off as thinking.
Also fixed three UI bugs found while testing a live multi-hour cast:
- A-/A+ font buttons had no effect (a hardcoded font-size on .ab-cv-row
always overrode the CSS variable they set).
- Typing a name + Enter in the "Assign to" popup (and drag-to-assign,
which reuses it) silently did nothing after the first cast/recast run
in a session - the popup is a page-lifetime singleton but its input
handlers closed over the first run's now-stale assignName/closePopup.
Every popup open now repoints them at the current run.
- "Split text to Unknown Speaker" split at the wrong spot when the
selected phrase repeated earlier in the same paragraph (indexOf found
the first occurrence, not the dragged one). Now uses the exact DOM
range offset instead.

The static-asset caching middleware used BaseHTTPMiddleware, which has a
known Starlette bug: a client disconnecting mid-StreamingResponse (the new
live-attribution SSE stream hitting its idle timeout) raced its internal
task group and raised "RuntimeError: No response returned", crashing that
request. Rewritten as plain ASGI middleware that only touches headers via
the raw send callable, removing the race.
Also found the real cause of the casting timeouts/405s: the streaming
attribution endpoint had its own lock instead of sharing the one the
blocking endpoint already used to serialize on the LLM's single slot -
letting a stream call and its own blocking fallback fire concurrently,
exactly the ghost-request pile-up that lock was built to prevent. Unified
onto one lock and added server-side logging for stream failures.
The "LLM Thinking" pane now shows the model's actual <think> reasoning
instead of the in-progress JSON answer echoed back at the user.

The LLM Reading card splits into thinking-stream (left) and passage
(right), fed by a new SSE endpoint that shares prompt-building and
parsing with the blocking one and falls back to it on any stream
failure (inactivity timeout, not overall). The deterministic resolver
no longer invents speakers from scenery nouns (PLATZ/GESICHTER/
KLEINIGKEIT) — person-noun whitelist plus a clause-subject pattern —
and gains the impersonal post-quote formula and strict two-person
alternation with colon/page/window guards. All reported failure cases
verified against the exact book sentences.

The recast/quality view's sidebar rebuilt its roster from only the
lines being checked, appearing to wipe every named character (the cast
itself was safe: named lines are never recast targets and increases in
Unknowns already roll back). The sidebar now seeds from the full cast
and refreshes during the run. Error notes fall back to the HTTP status
(statusText is empty on HTTP/2). The deterministic grammar resolver
runs before any LLM call in quality runs.

The LLM left ~44% of dialogue Unknown even with all deduction rules in
its prompt, so the mechanical ones now run in code per passage: colon
rule (with a non-agent-noun stoplist), post-quote inquit, and the "who
had spoken" pattern. Fills only Unknowns, never overrides the LLM.
Tested against the exact reported failure cases.

The saved casting prompt was the 2nd-quality verification prompt, so
first-pass attribution ran with the wrong job description and none of
the deduction rules — and the client-side prompt migration had no
anchor to upgrade. The server now appends the rules to any prompt
lacking them, and the saved prompt was reset to the default (backed up
to config/audiobook_prompt.backup.txt). Also: single-pass combined name
regex (a shorter alias could match inside a longer name's data-name
attribute and leak raw style="..." into the feed), stopword filter so a
comma-split alias like "Die, die den Vampir verließ" can't underline
every article, heading-like narration renders bold/centered, and A-/A+
font controls in the casting toolbar sharing the Rehearser Stage scale.

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.

The per-word <span> wrapping behind "click any word to assign" created
~100k DOM nodes at book scale and froze the tab on every feed redraw;
replaced with native caretRangeFromPoint word detection plus a single
reused hover overlay — same UX, zero extra DOM. Export button gained a
2s re-entry guard (queued clicks during a freeze fired as a download
burst) and now delivers one zip: the cast script in Markdown plus a
sheet per character. Character detail view gains a Generation Prompts
section — four fold-out copy boxes (Voice Design, Character Image,
SillyTavern card, Concept Art sheet) filled by one LLM call over the
full profile via the new /api/character-generate-prompts endpoint.

The casting prompt now teaches the deduction patterns behind most false
Unknown/Narrator assignments: colon-introduced quotes, post-quote inquit
attribution, pronoun resolution to the last-named matching-gender
character, addressee rule, strict two-person ping-pong, and role names
(Ork, Nachbar) as valid speakers. Saved prompts upgrade in place; the
2nd Quality Run prompt gets the same toolkit. The attribution language
hint falls back to detecting the book's language from its text instead
of relying on a usually-empty dropdown.

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

After a successful /api/voices fetch, results are written to sessionStorage
(key ttsvc_vc). On the next page load loadVoiceLibrary() reads the cache and
renders voices immediately before the network request completes, eliminating
the blank-list / skeleton flash entirely.
The background fetch always runs and overwrites the cache with fresh data.
Error handling is graceful: if the network fails but cache was served, the
error is suppressed (stale data stays visible). The Refresh button clears the
cache first to force a full reload cycle.
Silent-refresh logic (from v1.12.19) prevents the second loadVoiceLibrary()
call (engines.js batch E) from blanking already-rendered voices.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
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.

patch version series began).

- 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.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- Conversation Playground: STT/LLM/TTS/System prompt now full-width stacked.
- Fix conversation mic upload on ARM64: decode recording in-browser to
16 kHz mono WAV, bypassing server ffmpeg webm/EBML parser (with fallback).
- Document v1.10.0 (unified Library + character tags) and v1.10.1.

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.

Longer mixed DE/EN phrase covering dotted numbers, compound nouns,
umlauts, special characters, English technical vocabulary, time
formats and prose — reveals more of a voice's character per seed.

- voice-inspector: move `curGender` const before its first use — it was
declared at line 86 but referenced at line 61, causing a ReferenceError
(temporal dead zone) that silently aborted selectVoice() on every click
- Calc dB, Precompute, Batch Seeds now filter to checked voices when a
bulk selection is active, matching Benchmark's existing behaviour

- Auto-scroll to bottom is now gated on the user being within 80px of
the bottom. Scrolling up to review or edit a line freezes the feed
in place — new rows are still added, but the viewport doesn't move.
- Row-trimming is likewise suppressed while the user is scrolled up,
so old lines stay visible as long as they're being read/edited.
Trim limit raised from 80 → 600 rows so almost nothing is evicted.
- A floating "↓ Live" pill button appears at the bottom of the feed
whenever the user has scrolled up. Clicking it returns to the live
bottom and re-enables auto-scroll.

Casting view improvements:
- "LLM Reading…" row now shows a preview of the passage being processed.
A chevron button expands it to a full scrollable view of the passage
text (up to 260px), so you can follow what the LLM is reading live.
- Page-break dividers ("Page N") appear in the casting feed whenever the
source PDF page changes, giving a real-time view of page boundaries.
Bug fix:
- Page numbers in the Rehearser script were 0-indexed (PDF-internal) so
the first page break showed "Page 1" for what was PDF page 2, etc.
Now always emits 1-indexed page numbers (\f${page+1}).

When a PDF audiobook is cast and saved to the Rehearser, page breaks now
carry the source PDF page number. In the Stage view each divider renders
as "— Page N —" instead of the generic "— Page break —".
Implementation:
- audiobook.js: `audiobookBuildScript()` encodes the page number in the
form-feed line (\fN instead of bare \f) at each page boundary.
- rehearser-parse.js: `parseScript()` now matches `line.startsWith('\f')`
and extracts the trailing page number into `line.page`.
- rehearser.js: `buildScriptPage()` renders "— Page N —" when `line.page`
is set; `toScript()` round-trips the number back (\fN) so it survives
save/reload; `importPDFScript()` also encodes page numbers (\f<pageIdx+1>)
when importing screenplay PDFs directly.

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).

audiobookScopeText now records PDF page boundaries as character offsets in the
scope text; audiobookBuildScript realigns each segment against the source and
emits \f page-break markers at the nearest boundary. Saved/opened cast scripts
keep the book's pagination instead of collapsing to one flow.

- 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.

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.

Conversation playground:
- Live speech preview: MediaRecorder sends accumulated audio to
/api/transcribe-bytes every 2.5 s; interim Whisper result shown in
the text input field while recording. Web Speech API tried first as
a faster path when available (HTTPS/localhost).
- VAD auto-stop: AudioContext AnalyserNode measures RMS every frame;
auto-stops after 1.5 s silence with a visible countdown. Auto-stop
toggle to revert to click-to-stop.
- Hands-free mode: mic auto-restarts after the agent finishes speaking
via audio.ended event + generation-counter cancellation. Hands-free
toggle (on by default) to disable.
Navigation:
- Persist active section and sub-page in localStorage; hard-reload
returns to the same page instead of always jumping to My Voices.
