Adds a collapsible "🎲 Seed Finder" panel to the voice inspector pane.
Select a voice, expand the panel, set a seed range (default 1–15), and
click Run to generate audio samples with different seeds.
Each result row has Play and "Use this seed" buttons. "Use this seed"
saves the chosen seed to the faster-qwen3-tts voices.json via the new
/api/tts-voice-seed proxy endpoint (which calls /voice-seed on the TTS
server). The saved row gets a ✓ marker.
Test sentence auto-selects DE/EN mixed or EN-only based on voice name.

splitTextIntoChunks only split on sentence terminators (.!?), so structured
text separated by newlines was never chunked — the full page went as one
request, causing a TCP timeout that the browser reported as "Failed to fetch".
Fix: process each line individually before applying the sentence regex so
newline-separated segments become their own split points. Also move
generation.js from deferred batch E into the main feature batch C so
generateChunkedTts is always defined before the user can click Generate.

Storage: IndexedDB ('reh-library' DB, 'rehearsals' store).
Blobs (recorded mic audio) stored natively; no base64 overhead.
Library panel (Phase 1):
- List of saved rehearsals sorted by last update
- Each row: character-colour avatars, title, progress bar,
line count, recorded-clip count, date
- Active record highlighted in accent colour
- Open / Export .reh / Delete per-row buttons
- Import .reh button at the top
Transport bar (Phase 3):
- Save button (updates existing record if savedId set, else creates new)
- Export button (downloads current state as .reh JSON file)
Phase 4 (session complete):
- Save to library and Export .reh buttons
Data format (.reh file):
- JSON with version=1, title, script text, cast map, backend, lineIndex
- clips serialized with audio as base64 strings (mime + b64 fields)
- clipsFromJson restores Blob objects on import
Behaviour:
- Parsing a brand-new script resets savedId → safe to save as new record
- loadRecord() restores script, cast, lineIndex, clips and jumps to Phase 2
- renderLibraryList() called on init, after save, after delete, after import

- A4 paper page (white, serif font, shadow) renders the full script at once
so you can read ahead while rehearsing
- Each dialog block shows: character avatar (voice library photo or initial
letter), character name in their colour, TTS/Me badge, and dialog text
- Active line gets a blue left-border highlight and auto-scrolls into view
- Transport bar (sticky, above the script):
- Cast strip: all character avatars at a glance
- ⏮ Prev / ▶ Play all / ⏹ Stop / ⏭ Next / 🔁 Repeat
- Progress bar + line counter
- Auto-play: TTS lines synthesize, play, auto-advance; 'me' lines pause
and slide up a sticky recording overlay at the bottom of the page
- Recording overlay shows the line to speak, oscilloscope + meter,
Record / Stop / Keep & continue / Re-record / Skip
- voice-library.js now exports window._voices so the rehearser can resolve
voice IDs to has_picture flags and fetch /api/voice/picture/{id}

## Script Rehearser (new feature)
- New section s-rehearser.html + rehearser.js + nav/loader wiring
- Phase 1: paste/upload script (.txt), auto-detect characters from
'CHARACTER: dialog' or ALL-CAPS screenplay format
- Phase 2: assign a TTS voice per character, or mark 'I play this'
- Phase 3: step-through rehearsal — synthesizes other characters via TTS,
shows level-meter + oscilloscope for your own lines, records them from mic
- Phase 4: session summary with per-line audio playback + download
## Connect Apps
- Removed duplicate standalone MCP/speak/hotkey full-width cards
- Kept the integration-grid cards (they use the real server URL from JS)
- Added Global Hotkey Daemon as a proper integration card with snippet-hotkey
populated by integrations.js (uses proxyBase URL dynamically)
## About page
- GET /api/changelog endpoint reads CHANGELOG.md and returns it as text
- Collapsible 'Changelog' <details> card fetches and displays it lazily
## Try It Out
- Reorganised into three cards: Voice & backend / Text to synthesize / Generate
- Backend help panel moved below the voice row (not in the same flex row)
- Style instruction field gains a dynamic badge ('style-aware ✓' / 'weak style')
and a yellow warning when a non-style-aware backend is selected while the
field is filled — wired to both backend-select change and input events

Loader:
- Post-init modules (engines, ai-backends, generation, conversation) now
load AFTER the skeleton is removed instead of before. The UI is visible
~500 ms sooner on average; those four modules load while the user is
already browsing Voices / Clone / Design.
- Removed the sttReady event approach that was triggering a duplicate
/api/stt-backends call; init.js already populates all STT selects once
on startup.
Skeleton:
- Replaced the card-grid placeholder with a two-column workbench skeleton
(voice list rows on the left + inspector placeholder on the right) that
matches the real My Voices layout.
Connect Apps:
- MCP Server, /speak REST endpoint, and Global hotkey daemon sections
moved from Settings → About to Connect Apps, where they belong.
- About page now has GitHub + Releases links instead.
Clone section:
- Added a hint note beneath the sample-text textarea reminding the user
to replace the placeholder name (Sam / Alex / Marco …) with their own.

Root cause: VERSION was not volume-mounted, so the server always reported
1.2.0, causing browsers to serve 1-year-immutable cached JS even after
code changes.
Fixes:
- docker-compose.yml: add ./VERSION:/app/VERSION:ro volume mount.
After `docker compose up -d`, the server reads the current VERSION file
and JS is cache-busted by the correct version string.
- loader.js: append session timestamp to _appVersion so every page load
generates a unique JS URL. JS is always fresh regardless of whether
VERSION is current, at the cost of one network round-trip per file per
session (acceptable for a local tool).
- s-clone.html: embed EN default text directly in the textarea so the
field is never empty even before JS runs.
- voice-clone.js: remove the 'skip if already filled' guard in
initCloneSampleText so navigating back always resets to the language
text; call refreshSttBackends on load with sttReady event fallback.
- stt.js: dispatch 'sttReady' event after all STT listeners are wired.

1. Sample text: expose initCloneSampleText as a window function and call
it from nav.js runSideEffects when the clone section is activated,
ensuring the textarea is always populated even if the IIFE ran before
the element existed.
2. Better sample texts: all 8 languages rewritten to ~38 words / ~15 s,
first-person, phonetically rich, proper Unicode diacritics.
3. Live mic monitor: a level-meter (18-bar) + scrolling oscilloscope
canvas (ring-buffer, 300 px, colour-coded) added to the microphone
card. "Check level" / "Stop monitor" buttons start/stop it
independently; clicking Record starts it automatically.
Uses raw mic constraints (no echo-cancel / AGC) for cleaner voice clone
audio. Mic gain slider and dB readout included.
4. Recording quality: MediaRecorder now requests audioBitsPerSecond:256000
in both voice-clone.js and stt.js.
5. STT engine picker: Recognition engine <select> + Refresh button added
above the Auto-transcribe button in Step 3. refreshSttBackends() now
syncs both stt-tts-stt-backend and clone-stt-backend. The transcribe
call passes the chosen backend to /api/transcribe.
6. File input: explicit extension list added to accept= for OGG/OPUS.
7. CSS: .mic-live-wave style added (dark/light theme variants).

Adds the 'Read aloud' sample-sentence box back to the microphone card
in the Clone a Voice tab. Language switcher covers EN/DE/IT/ES/FR/PT/NL/PL
with phonetically diverse sentences (same as the My Voices panel).
Uses the existing .sample-read-box / .sample-sentence CSS so it looks
identical to the equivalent panel in the voice library.

Sentence text in typing bubble:
- Backend sends 'text' field with each audio SSE event (the sentence
being synthesised)
- Frontend audio queue stores {url, text} pairs
- playNextAudio() writes the sentence text into the '...' typing bubble
when LLM tokens haven't arrived yet (convCurrentSentenceBubble)
- convCurrentSentenceBubble cleared as soon as first LLM token arrives
so normal streaming takes over seamlessly
VAD noise fixes:
- VAD_THRESHOLD: 0.01 → 0.02 (background noise no longer counts as speech)
- VAD_MIN_REC_MS: 400 → 800ms (8/10s wait before silence detection starts,
gives user time to begin speaking without initial noise triggering send)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Speech gate (silence detection):
- vadHadSpeech flag: VAD auto-stop cancels without calling STT when no
speech was detected (fixes "[STT] No speech detected → gibberish" loop)
- cancelNextBlob flag: onstop skips processBlob when VAD cancels silently
- vadLastVoiceMs: gates preview transcription on actual detected speech
(prevents "reich" hallucination on initial silence chunks)
Hallucination filter:
- Client: HALLUCINATION_RE strips known Whisper phantoms from preview
- Server: _is_hallucination() in generate() treats "reich" / "danke" /
"thank you" etc. as "No speech detected" → never reaches LLM
Latency:
- VAD_SILENCE_MS: 1500 → 1000 ms (sends 500 ms sooner per turn)
- VAD_MIN_REC_MS: 500 → 400 ms
- MediaRecorder timeslice: 2500 → 1500 ms (preview text updates faster)

Replace serial LLM-wait-TTS with overlapped execution:
- LLM streams via background thread → asyncio.Queue (non-blocking event loop)
- _sentence_split() detects sentence boundaries in the token stream
- asyncio.create_task fires TTS for each sentence immediately — TTS for
sentence 1 runs while LLM is still generating sentences 2, 3, …
- Audio chunks stream to frontend in order as each task completes
- Time-to-first-audio drops from (LLM total + TTS total) to
roughly (LLM time-to-first-sentence + TTS latency for one sentence)
Frontend audio queue:
- enqueueAudio() / playNextAudio() chain multi-chunk responses seamlessly
- clearAudio() stops playback and cancels queue on new turn or mic click
- scheduleAutoMic() waits for queue to drain before restarting mic
- Error paths clear the queue to avoid stale audio playing after failure
Also fix missing contextlib import (silent bug when audio temp files
needed cleanup in the STT path).

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.

Previously: container names and dynamic card URL overrides only
written to localStorage — lost when accessing from a different
browser or after clearing browser data.
Now:
- engine_container_names added as persisted settings key (dict)
- All container name inputs tagged data-cn-key for loadSettings() lookup
- loadSettings() restores container names + dynamic URLs from server
- settings.js exposes _saveEngineContainerNames() and
_saveEngineLocalUrls() globally so engines.js / ai-backends.js
can call them on every input event
- Static cards (ai-backends.js initStaticDockerManagement): reads
saved name from engine_container_names first, localStorage fallback
- Dynamic Docker stack cards (engines.js): same priority for both
URL and container name; both write to server on change
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Move mic-blocked warning into conv-chat-window (prepend) so it scrolls
with the chat instead of pushing the input bar off-screen
- Remove min-height:400px from conv-chat-window; give conv-chat-panel a
viewport-relative height so the input bar is always visible at the bottom
- loader.js: append ?v=<timestamp> to section fetches to bust browser cache
(was serving stale s-conversation.html after updates)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add VERSION file (1.1.0) at repo root

- [1.0.0] 2026-05-28 — all pre-session features documented
- Compare links at bottom pointing to GitHub
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Frontend:
- Add pill-shaped text input + send button (→) to the left of the mic button
- Enter key or → click sends text directly without recording audio
- Input is disabled while a turn is processing; cleared on submit
- Welcome message updated to mention both input methods
- New CSS: .conv-input-bar, .conv-text-row, .conv-text-inp, .conv-send-btn,
.conv-divider (visual separator between text and mic sections)
Backend:
- /api/conversation/turn: audio is now optional (UploadFile | None)
- New text form field — when provided, STT step is skipped and text is
used as the transcript directly; SSE emits transcript event with stt_ms=null
- Raises 400 if neither audio nor text is supplied
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Engine cards (all TTS + STT, dynamic Docker stack + static):
- Container name field now always visible on every card (was hidden for
absent/not-installed containers)
- Connect button moved out of URL row into a dedicated dc-controls-row;
restyled as solid blue primary CTA
- Connect now toggles to Disconnect (green) when reachable, persists state
- On successful connect, URL is auto-applied to Settings so the backend
appears in TTS/STT dropdowns immediately — no separate "Use as" click needed
- "Use as TTS/STT" button updated: larger, teal "apply" style, tooltip,
gains .active highlight once applied, right-aligned as the trailing action
- Unified control order on every card: [Connect/Disconnect] [Stop|Start|Restart] [Use as →]
- initStaticDockerManagement rebuilt to use the same dc-controls-row layout
as dynamic cards, moving .llm-local-ping from URL row at init time
Conversation section:
- Fix chrome://flags URL being white-on-grey inside the mic-blocked warning
box (global code{background:var(--panel)} overrode the inherited white text)
- Inline-styled the <code> element with a dark translucent background
- Added a Copy button so users can copy the URL without selecting invisible text
