-## [0.5.0] — 2026-08-13
+## [Unreleased]
 
 **Highlights**
 
-- The app is now **VoiceStudio** (previously OmniVoice-Studio) — one waveform-and-spark identity across the app, docs and installers. Your data folder, settings and Docker image paths stay put.
-- **Model Catalogue** — engines and models in one workspace: every TTS, transcription and LLM engine with its device routing and install state, defaults picked there.
-- Switch TTS, ASR and LLM engines from the status bar or any workspace — ready-only choices, memory status, environment-pin protection, `Ctrl/Cmd+E`. (#1530)
-- Lend another machine's GPU with a join code and a QR scan — a Compute control in the status bar picks where jobs run, and several people can share one GPU box with revocable, certificate-pinned connections. (#1516, #1496)
-- Server mode is locked down: admin actions require an API key (#1525), and the remote UI exchanges it for short-lived sessions that never sit in browser storage or WebSocket URLs (#1528) — thanks @bultodepapas!
-- A faster, cleaner Dub workspace for multilingual production, with a production command bar and per-language cards. (#1489)
-- The demo audio and video the app always advertised now actually ship, rendered by VoiceStudio's own engine. (#1517)
-- Dictation works on Wayland now — the portal shortcut actually fires (#1490, #1526) — and the recording pill is back on every desktop.
-- The Launchpad wears the project's signal-field waveform artwork over a quieter, borderless layout. (#1533)
-- The catalogue reads as headroom, not breakage: available engines sort first, uninstalled ones say what they need (#1531), and the LLM row names the provider that actually answers (#1538).
-- Gallery voices can be saved as local profiles — audio lands in your profile store with validated, content-addressed references. (#1542)
+- Docker/server mode now requires an API key for remote changes and side-effectful admin checks across workers, engines, media tools, MCP, pronunciation, diagnostics, and LLM providers. (#1525) — thanks @bultodepapas!
+- The unified Support page no longer throws while opening a section in browsers or test environments without `scrollIntoView`. (#1525) — thanks @bultodepapas!
+- A faster, cleaner Dub workspace for multilingual production (#1489)
+- VoiceStudio now gives the app, desktop chrome, documentation, and package metadata one clear identity
+- A local-first creative studio: voice cloning, design, dubbing, dictation, stories, audiobooks, and transcription without a subscription meter
+- Reliability first: automatic cache repair, truthful hardware routing, safer sidecars, and actionable recovery instead of mystery failures
+- Security boundaries now match the product: native file access stays native, untrusted network destinations fail closed, and public errors keep private diagnostics local
+- RTX 40-series GPUs are used again instead of being sent to the CPU
+- A warning before a slow generation, rather than after a five-minute wait
+- The watermark can be turned off in Settings, as the docs always said
+- Your other GPU can take the work now — send individual jobs to a second machine, opt-in
+- More than one person can share one GPU machine, without shell access to it or taking turns
+- A Model Catalogue workspace: every engine and model in one place, with the defaults set there
+- Workspace tabs in the title bar, if you prefer them to the icon rail (#1412)
+- macOS support now matches what the app actually delivers
+- Linux AppImage: a blank white window on rolling distros (Mesa 26.1+) now starts normally
+- Apple Silicon: transcription no longer needs a system ffmpeg, as the docs always said — thanks @gambletan! (#1436)
+- A failed audiobook chapter says why, instead of turning red and saying nothing

+- The guard that keeps transcription on the degrading ASR loader now scans the whole backend, not just the routers — a service that transcribes on a request's behalf skipped `ensure_loaded()` just as thoroughly. (#1519) — thanks @ahov520!
+- The Linux app icon is no longer blank. Every AppImage since v0.4.2 shipped `.DirIcon` as an absolute symlink into the machine that built it (`/home/runner/work/…`), so the link dangled on every user's computer and file managers, app menus and desktop integration all drew nothing.

+### Added

+- The demo audio the app has always advertised now actually ships: previews for all seven voice-design presets, the three dictation replay clips, and the dubbing demo's source video plus four dubbed languages with subtitles. Every one of those was a dead link before — the tooling that renders them required macOS, so on Windows and Linux the files were never built. (#1517)
+- Demo assets are rendered by VoiceStudio's own engine, so the tooling runs wherever the app does, and the demos are made by the thing they demonstrate. (#1517)
+
+### Added
+
+- A machine can now join a control plane from the app: Settings → System → Remote workers → **Lend this machine's GPU**, paste the join code, done — no environment variables and no restart. The address travels with the code, so the machine reconnects on its own afterwards. (#1516)
+- Join codes and connection strings are shown as a **QR code** alongside the text, with a live expiry countdown — scan it from the other machine instead of retyping forty characters. (#1516)
+- A **Compute** control in the status bar: pick local or a remote machine, turn remote workers on or off, and mint a join code without opening Settings. It appears only once you have opted in or enrolled a machine. (#1516)

 ### Changed
 
-- Gallery personas now preview through the local backend, retain their complete voice-design recipe, and open directly in Voice, Stories, or Audiobook. (#1542)
-- Support amount choices now use every theme's shared card, accent and focus tokens. (#1530)
 - Sponsoring, commercial licensing and getting in touch are one page now. They answered the same question between them and each used to live somewhere else, so they are three sections on a single scroll — the footer heart, the commercial-licence links and Contact all land on it, at the section you asked for. (#1522)
 - Model Catalogue switches panes with tabs instead of a two-state toggle, and the Engine Compatibility Matrix's TTS / ASR / LLM switcher is now tabs too — arrow-key navigable, and each tab still shows the engine it would use. (#1522)
 - Engines you can actually use sort to the top of the compatibility matrix, and an unavailable engine's name recedes instead of the whole row fading — the status badge and GPU chips that say *why* it is unavailable stay legible. (#1522)
 - Remote workers reads as a device list: status dot, address, latency, a live task meter, resident models and last-seen per machine, with housekeeping actions revealed on hover and a three-step empty state. (#1516)
 - The GPU picker and the new status-bar control paint their status dots and menu surfaces from themed tokens instead of fixed palette classes, so they stop showing Gruvbox colours on Midnight and Catppuccin. (#1516)
 - Dictation shows the pill again: a capture puts a small always-on-top capsule near the bottom of the screen you are working on — listening, transcribing, the result, and any error — and takes it away when the session ends. It never takes focus, so the text still lands in the app you were typing into. On Wayland the compositor decides where it sits; everywhere else it is bottom-centred.
+- Remote workers reads as a device list: status dot, address, latency, a live task meter, resident models and last-seen per machine, with housekeeping actions revealed on hover and a three-step empty state. (#1516)
 - Engines and models moved out of Settings into a new Model Catalogue workspace, reachable from the icon rail (or the title-bar tabs); Settings → Engines and Settings → Models now point there, and Settings keeps the models directory and Hugging Face mirror.
 - The Settings sidebar is keyboard-navigable: ⌘K / Ctrl+K jumps to the filter, ↑/↓ and Home/End move between categories, and Enter or ↓ from the filter drops into the list. Matching text in a filtered category name is highlighted, and group headers stay pinned while the list scrolls.
 - The Launchpad has a quieter, more spacious look: borderless feature tiles that light up on hover or keyboard focus, plain-numeral counts, hairline section rules, and one shared page column for the hero, tiles, recent files and project lists.

 ### Fixed
 
-- AMD/ROCm hosts no longer crash ASR with "CUDA driver version is insufficient": ROCm torch reports itself as CUDA, but whisperx/faster-whisper run on CTranslate2, which is NVIDIA-only — they now take the CPU path there, and auto-detect prefers pytorch-whisper, which genuinely uses the HIP GPU. (#1529)
-- Crash reports now carry the crashed run's own stderr: the shared error log is append-only with per-run offsets, so a restart can no longer overwrite the dying process's final output with the replacement's healthy startup. (#1510)
-- Wayland: a stale portal identity no longer kills the dictation shortcut for the whole session. The desktop entry the app writes for the GlobalShortcuts portal could point at a binary that has since moved (a `cargo clean`, a relocated AppImage) — GNOME then refuses the bind with "App info not found" and the hotkey silently dies. The entry is validated and rewritten at startup now. (#1526)
-- The guard that keeps transcription on the degrading ASR loader now scans the whole backend, not just the routers — a service that transcribes on a request's behalf skipped `ensure_loaded()` just as thoroughly. (#1519) — thanks @ahov520!

 - The first-run "Choose a comfortable UI size" screen no longer stutters while you sit there. Applying a scale resizes the window's own viewport, which the screen was reading back to re-pick a size — so it flipped between two sizes forever without anyone touching it. (#1514)

 - Translation through LM Studio works.

 - Generation that silently dropped the end of the input now says so. When an engine returns no audio for part of the text the result sounds clean and is simply short, so the only way to notice was to read along; the backend log now names the sentences that produced nothing. (#1330)

+- `OMNIVOICE_ALLOWED_ORIGINS` is finally documented: a browser loading the UI from another machine's origin needs the backend's CORS allow-list, which neither server mode nor trusted networks touches — thanks @vanderlpp! (#1348)
 
 ### CI
 
-- Windows CI falls back to a static ffmpeg build when the Chocolatey feed is down, instead of failing the run. (#1542)
-- The stdio wire protocol every engine sidecar speaks is now tested once across all nine of them, instead of against a single engine — a bug in any one sidecar's copy gets caught — thanks @paoloantinori! (#1408)
 - Windows smoke tests stopped silently passing a broken ffmpeg install, and every smoke leg is now budgeted for a cold dependency install. (#1290)
 - Test suites no longer leak config paths or model-manager shutdown state into one another, which had been failing unrelated pull requests. (#1269)
-- The nightly preview build stopped refusing to publish its own healthy updater manifest when the macOS legs finished a few minutes ahead of the slowest one — Preview-channel users were silently left without new builds.

-
-- 🏷️ **A new name** — VoiceStudio (previously OmniVoice-Studio): one waveform-and-spark identity across app, docs, and installers. Your data folder, settings, and Docker image paths stay put.
-- 📚 **Model Catalogue** — engines and models in one workspace: every TTS, ASR, and LLM engine with its device routing and install state; pick defaults, install or remove weights.
-- ⚡ **Engine quick-switch** — change TTS/ASR/LLM engines from the status bar or anywhere with <kbd>Ctrl</kbd>/<kbd>Cmd</kbd>+<kbd>E</kbd> — ready-only choices, memory status, environment-pin protection.
-- 🖧 **Remote GPU workers** — lend another machine's GPU with a join code and a QR scan; a **Compute** control picks where jobs run, and several people can share one GPU box over revocable, certificate-pinned connections.
-- 🔐 **Hardened server mode** — admin actions require an API key, exchanged for short-lived scoped sessions that never sit in browser storage or WebSocket URLs.
-- 💾 **Gallery voices → local profiles** — save any gallery voice as a profile of your own and use it in every picker.
-- 🎤 **Dictation on Wayland** — the portal shortcut actually fires now, and the recording pill is back on every desktop.

 ## ❓ FAQ
 
+<details>
+<summary><b>Is this really as good as ElevenLabs?</b></summary>
+<br/>
+Honest answer: <b>it depends on what you're doing.</b>
+
+<b>Where VoiceStudio is genuinely competitive:</b> voice cloning from a clean reference clip (state-of-the-art open diffusion TTS), language coverage (646 languages vs. their 32), and everything structural — no per-character billing, no usage caps, no audio leaving your machine, full pipeline customizability (14 TTS engines, 11 ASR engines, your choice of translation).
+
+<b>Where ElevenLabs still wins:</b> out-of-the-box consistency and polish, especially for English TTS. Their one model is heavily tuned; our quality depends on which engine you pick, your hardware, and — for cloning — the reference audio (a dry, close-mic clip clones dramatically better than a noisy or echoey one).
+
+<b>For dubbing specifically:</b> a dub is a chain — transcription → translation → cloning → synthesis — only as good as its weakest link on <i>your</i> source material. If parts come out incoherent, check the segment table's <i>original</i> text first: when the transcription is already wrong, switch the ASR engine or use cleaner source audio — that's usually the fix, not the voice.
+
+Try it on your real material — it's free and takes one download. Many users replace ElevenLabs outright; some keep both. Both outcomes are fine with us.
+</details>
+
+<details>
+<summary><b>Why doesn't a longer reference clip sound more like me?</b></summary>
+<br/>
+Because VoiceStudio's cloning is <b>zero-shot</b>: your clip is a <i>prompt</i> the model conditions on at generation time — it is never trained on. Feeding it 2 hours doesn't teach it your voice; past a short window the extra audio is simply not used. The dubbing pipeline's reference builder targets ~8 s and hard-caps at 15 s (<code>backend/services/speaker_clone.py</code>), and engines cap the prompt themselves (VoxCPM2 trims references to 30 s). This is different from ElevenLabs <i>Professional</i> Voice Cloning, which fine-tunes a model on hours of your audio — that's a training job, not a bigger prompt.
+
+<b>What actually moves clone quality is the clip, not its length.</b> Zero-shot cloning mirrors the acoustics and delivery of the prompt, so: record 5–15 seconds (~8 s is the sweet spot) of continuous natural speech, close to the mic, in a quiet room with no reverb or music — an echoey clip clones echoey. One speaker only, and read in the tone and pace you want the output to have, because the clone copies your delivery, not just your timbre. Recording a few candidate clips and comparing results beats any amount of extra footage.
+
+<b>Want audiobook-grade, trained-on-your-voice fidelity?</b> That path exists, but it's offline fine-tuning, not an in-app button: prepare a dataset of your recordings (<a href="docs/data_preparation.md">docs/data_preparation.md</a>) and fine-tune the bundled checkpoint via <code>init_from_checkpoint</code> (<a href="docs/training.md">docs/training.md</a>). Fair warning — it's a technical, command-line workflow that needs a capable GPU and hours of transcribed audio. In-app fine-tuning / long-reference "professional" cloning is on the <a href="docs/ROADMAP.md">roadmap</a> as research only; no promised date.

-### First-party administrator sessions

-The bundled UI uses a narrower protocol:
-
-1. `POST /api/auth/session` receives the master in an `Authorization` header
-   exactly once and selects `{"transport":"cookie"}` for exact same-origin
-   browsers or `{"transport":"bearer"}` for Tauri/cross-origin clients.
-2. Cookie transport returns `204` and sets `ov_session` as HttpOnly,
-   SameSite=Strict, path `/`, with an eight-hour maximum lifetime. Bearer
-   transport returns an opaque `ovs_admin_session_…` value which the UI keeps
-   in **sessionStorage only**, bound to the exact backend base URL. Bearer JSON
-   responses include both `expires_at` and a bounded `expires_in`; the UI uses
-   the relative lifetime when available so clock skew between a remote GPU host
-   and the browser cannot reject a valid session. `expires_at` remains for
-   backward compatibility with older clients and servers.
-3. `DELETE /api/auth/session` revokes the session. Removing or rotating
-   `OMNIVOICE_API_KEY`, backend restart, explicit logout, and the eight-hour
-   deadline also invalidate it.
-
-The master is never written to localStorage/sessionStorage, never returned by
-the backend, and never placed in a WebSocket URL. Legacy `ov_api_key` browser
-storage is deleted before migration waits on the network. All auth responses,
-including errors, carry `Cache-Control: no-store`.
-
-Failed session exchanges are limited per client to ten attempts in a rolling
-60-second window and then return `429` with `Retry-After`. A correct master key
-is always evaluated and clears the failure window, so an attacker cannot lock
-an operator out by deliberately exhausting the limit.
-
-Cookie-authenticated mutations require both an exact allowed `Origin` and
-`X-VoiceStudio-CSRF: 1`. Side-effectful GET actions additionally require the
-browser's `Sec-Fetch-Site: same-origin`. Bearer/header clients are not subject
-to the ambient-cookie CSRF check.

 # Spec — TASK #26: Gallery "Use in Stories" / "Set as Audiobook default" + create-voice handoff
 
-> **Implemented (2026-08-13).** Gallery and Community persona cards now materialize once and hand the returned profile directly to Studio, the current Stories cast, or the current Audiobook default. The implementation uses the unified `longformSlice` that superseded the store additions proposed below; the remainder of this document preserves the original design record.
-
 ## TL;DR
 
 Today the Gallery's "Use voice" action materializes an archetype/community voice into a profile and hard-codes a handoff into the **Studio** synthesis view (`frontend/src/pages/VoiceGallery.jsx:199-210` for archetypes; `frontend/src/App.jsx:254-268` for the studio-side pickup). There is no path from the Gallery into the **Stories** cast or the **Audiobook** default narrator. This task adds two quick-actions to gallery + community cards — "Use in Stories" and "Set as Audiobook default" — that (a) materialize the voice into a real profile (same backend call as today) and (b) land it in the right destination: appended to the Stories cast as a new character, or set as the persisted Audiobook default voice. The Audiobook default currently has no store binding at all, so this task also promotes it from local `useState` to a persisted store field.
