add --force-reinstall --no-deps to torchaudio CUDA install

Move audio validation and saving to thread pool so librosa/ffmpeg decoding
doesn't block the async event loop. Combine validate + load into a single
pass to avoid decoding the file twice. Add 50 MB upload limit and chunked
reads to prevent unbounded memory allocation.

Closes #278

+description: Use this skill to draft or update the [Unreleased] section of CHANGELOG.md from the actual changes since the last tag. Run this at any point during development to keep a working copy of the release narrative. Does NOT bump versions or create tags.
+---
+
+# Draft Release Notes
+
+## Goal
+
+Update the `[Unreleased]` section at the top of `CHANGELOG.md` with a narrative release story based on the real changes since the last tag. This is a **non-destructive working copy** — run it as many times as you want during development.
+
+## Workflow
+
+1. **Identify the last release tag and gather changes.**
+
+   ```bash
+   LAST_TAG=$(git tag --list "v*" --sort=-v:refname | head -n 1)
+   echo "Last tag: $LAST_TAG"
+   ```
+
+   Then collect raw material from three sources:
+
+   a. **Commit log since last tag:**
+   ```bash
+   git log --oneline "$LAST_TAG"..HEAD
+   ```
+
+   b. **GitHub-generated release notes preview** (PR titles, new contributors):
+   ```bash
+   gh api repos/:owner/:repo/releases/generate-notes \
+     -f tag_name="vNEXT" \
+     -f target_commitish="$(git rev-parse HEAD)" \
+     -f previous_tag_name="$LAST_TAG" \
+     --jq '.body'
+   ```
+
+   c. **Diff stat for theme analysis:**
+   ```bash
+   git diff --stat "$LAST_TAG"..HEAD
+   ```
+
+2. **Draft the release narrative.**
+
+   Write markdown for the `[Unreleased]` section following the format below. Do not include the `## [Unreleased]` heading itself — just the body content.
+
+3. **Update CHANGELOG.md.**
+
+   Replace everything between `## [Unreleased]` and the next `## [` heading with the new draft. Preserve the HTML comment header and all existing release sections below.
+
+   The `[Unreleased]` section must always exist and always be the first section after the header comments.
+
+4. **Do NOT commit, tag, or bump versions.** Just leave the file modified in the working tree.
+
+## Release Story Format
+
+Structure the `[Unreleased]` section like this:
+
+```markdown
+## [Unreleased]
+
+<One strong opening paragraph: what this release is about and why it matters.
+Tie it to concrete shipped changes. No vague hype.>
+
+<One paragraph on major technical shifts, if applicable.>
+
+### <Feature/Theme Group>
+- Bullet points with specifics
+- Reference PRs where available: ([#123](https://github.com/jamiepine/voicebox/pull/123))
+
+### <Another Group>
+- ...
+
+### Bug Fixes
+- ...
+```
+
+### Style Guidelines
+
+- **Factual and specific.** Every claim should trace to a real commit or PR.
+- **Narrative over list.** Lead with paragraphs that tell the story, then support with bullets.
+- **Group by theme, not by commit.** Cluster related changes under descriptive headings.
+- **Reference PRs** where they exist, but don't fabricate them.
+- **Skip trivial chores** (typo fixes, CI tweaks) unless they're the bulk of the release.
+- **Match the voice of existing releases** — look at the v0.2.1 and v0.2.3 entries in CHANGELOG.md for tone reference.
+
+## When There Are No Changes
+
+If `git log "$LAST_TAG"..HEAD` is empty, leave the `[Unreleased]` section empty (just the heading) and tell the user there's nothing to draft.
+
+## Notes
+
+- This skill only touches the `[Unreleased]` section. It never modifies stamped release sections.
+- The agent can be asked to run this skill at any point — mid-feature, before a PR, or right before cutting a release.
+- The `release-bump` skill depends on this draft being up to date before it finalizes.

+description: Use this skill to finalize a release. It stamps the [Unreleased] changelog section with a version and date, runs bumpversion to update all version files, and creates the release commit and tag. Only run this when you're ready to ship.
+---
+
+# Release Bump
+
+## Goal
+
+Finalize the changelog draft, bump the version across all tracked files, and create a tagged release commit. After this skill runs, the repo has a clean release commit and tag ready to push.
+
+## Prerequisites
+
+- `gh` CLI installed and authenticated (`gh auth status`).
+- `bumpversion` installed (`pip install bumpversion` or available in the project venv).
+- The `[Unreleased]` section of `CHANGELOG.md` should already contain the release narrative. If it's empty or stale, run the `draft-release-notes` skill first.
+
+## Workflow
+
+1. **Verify the working tree is clean** (except `CHANGELOG.md` which may have the draft).
+
+   ```bash
+   git status --porcelain
+   ```
+
+   Only `CHANGELOG.md` (and optionally `.agents/` files) should be modified. If there are other uncommitted changes, stop and ask the user to commit or stash them first.
+
+2. **Determine the bump level.**
+
+   Ask the user if not specified: `patch`, `minor`, or `major`. Check the current version:
+
+   ```bash
+   grep '^current_version' .bumpversion.cfg
+   ```
+
+3. **Stamp the changelog.**
+
+   Read the current `[Unreleased]` content from `CHANGELOG.md`. Compute the new version (based on bump level and current version). Then:
+
+   a. Replace the `## [Unreleased]` section body with an empty placeholder.
+   b. Insert a new stamped section immediately after `## [Unreleased]`:
+
+   ```markdown
+   ## [Unreleased]
+
+   ## [X.Y.Z] - YYYY-MM-DD
+
+   <the content that was in [Unreleased]>
+   ```
+
+   c. Update the reference links at the bottom of the file:
+   - Change the `[Unreleased]` link to compare against the new tag
+   - Add a new link for the new version
+
+   ```markdown
+   [Unreleased]: https://github.com/jamiepine/voicebox/compare/vX.Y.Z...HEAD
+   [X.Y.Z]: https://github.com/jamiepine/voicebox/compare/vPREVIOUS...vX.Y.Z
+   ```
+
+4. **Stage the changelog.**
+
+   ```bash
+   git add CHANGELOG.md
+   ```
+
+5. **Run bumpversion.**
+
+   ```bash
+   bumpversion --allow-dirty <patch|minor|major>
+   ```
+
+   The `--allow-dirty` flag is needed because `CHANGELOG.md` is already staged. bumpversion will:
+   - Update version strings in all tracked files (see `.bumpversion.cfg`)
+   - Create a commit with message `Bump version: X.Y.Z -> A.B.C`
+   - Create a tag `vA.B.C`
+
+   The staged `CHANGELOG.md` will be included in this commit automatically.
+
+6. **Verify results.**
+
+   ```bash
+   git show --name-only --stat HEAD
+   git tag --list "v*" --sort=-v:refname | head -n 5
+   ```
+
+   Confirm the commit contains:
+   - `CHANGELOG.md`
+   - `.bumpversion.cfg`
+   - `tauri/src-tauri/tauri.conf.json`
+   - `tauri/src-tauri/Cargo.toml`
+   - `package.json`
+   - `app/package.json`
+   - `tauri/package.json`
+   - `landing/package.json`
+   - `web/package.json`
+   - `backend/__init__.py`
+
+   Confirm the new tag exists.
+
+7. **Do NOT push** unless the user explicitly asks. Report the tag name and suggest:
+
+   ```
+   Ready to push. When you're ready:
+     git push origin main --follow-tags
+   ```
+
+## Version Calculation Reference
+
+Given current version `X.Y.Z`:
+- `patch` -> `X.Y.(Z+1)`
+- `minor` -> `X.(Y+1).0`
+- `major` -> `(X+1).0.0`
+
+## Error Recovery
+
+- If bumpversion fails, the tag won't exist. Fix the issue and re-run — bumpversion is idempotent as long as the tag doesn't already exist.
+- If you need to undo a release commit (before pushing): `git tag -d vX.Y.Z && git reset --soft HEAD~1`
+- Never amend a release commit that has been pushed.
+
+## Notes
+
+- When the tag is pushed, the release CI (`.github/workflows/release.yml`) automatically extracts the matching version section from `CHANGELOG.md` and uses it as the GitHub Release body. No manual copy-paste needed.
+- The release commit message is controlled by `.bumpversion.cfg` (`Bump version: X.Y.Z -> A.B.C`). Do not override it.
+- If you need to manually update the GitHub Release body after the fact: `gh release edit vX.Y.Z --notes-file <(sed -n '/## \[X.Y.Z\]/,/## \[/p' CHANGELOG.md | head -n -1)`

 # Changelog
 
-All notable changes to Voicebox will be documented in this file.
-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
-and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
-
 ## [Unreleased]
 
-### Fixed
-- **Profile Name Validation** - Added proper validation to prevent duplicate profile names ([#134](https://github.com/jamiepine/voicebox/issues/134))
-  - Users now receive clear error messages when attempting to create or update profiles with duplicate names
-  - Improved error handling in create and update profile API endpoints
-  - Added comprehensive test suite for duplicate name validation
+This release rewrites the backend into a modular architecture, migrates the documentation site to Fumadocs, and ships a batch of bug fixes and UI polish across the stack.
 
-## [0.1.0] - 2026-01-25
+The backend's 3,000-line monolith `main.py` has been decomposed into domain routers, a services layer, and a proper database package. A style guide and ruff configuration now enforce consistency. On the frontend, model loading status is now visible in the UI, effects presets get a dropdown, and several race conditions and accessibility gaps are closed.
 
-### Added
+### Backend Refactor ([#285](https://github.com/jamiepine/voicebox/pull/285))
+- Extracted all routes from `main.py` into 13 domain routers under `backend/routes/` — `main.py` dropped from ~3,100 lines to ~10
+- Moved CRUD and service modules into `backend/services/`, platform detection into `backend/utils/`
+- Split monolithic `database.py` into a `database/` package with separate `models`, `session`, `migrations`, and `seed` modules
+- Added `backend/STYLE_GUIDE.md` and `pyproject.toml` with ruff linting config
+- Removed dead code: unused `_get_cuda_dll_excludes`, stale `studio.py`, `example_usage.py`, old `Makefile`
+- Deduplicated shared logic across TTS backends into `backends/base.py`
+- Improved startup logging with version, platform, data directory, and database stats
+- Fixed startup database session leak — sessions now rollback and close in `finally` block
+- Isolated shutdown unload calls so one backend failure doesn't block the others
+- Handled null duration in `story_items` migration
+- Reject model migration when target is a subdirectory of source cache

+The "it works in dev but not in prod" release. This version fixes a series of PyInstaller bundling issues that prevented model downloading, loading, generation, and progress tracking from working in production builds.
+
+### Model Downloads Now Actually Work
+
+The v0.2.1/v0.2.2 builds could not download or load models that weren't already cached from a dev install. This release fixes the entire chain:
+
+- **Chatterbox, Chatterbox Turbo, and LuxTTS** all download, load, and generate correctly in bundled builds
+- **Real-time download progress** — byte-level progress bars now work in production. The root cause: `huggingface_hub` silently disables tqdm progress bars based on logger level, which prevented our progress tracker from receiving byte updates. We now force-enable the internal counter regardless.
+- **Fixed Python 3.12.0 `code.replace()` bug** — the macOS build was on Python 3.12.0, which has a [known CPython bug](https://github.com/pyinstaller/pyinstaller/issues/7992) that corrupts bytecode when PyInstaller rewrites code objects. This caused `NameError: name 'obj' is not defined` crashes during scipy/torch imports. Upgraded to Python 3.12.13.
+
+### PyInstaller Fixes
+
+- Collect all `inflect` files — `typeguard`'s `@typechecked` decorator calls `inspect.getsource()` at import time, which needs `.py` source files, not just bytecode. Fixes LuxTTS "could not get source code" error.
+- Collect all `perth` files — bundles the pretrained watermark model (`hparams.yaml`, `.pth.tar`) needed by Chatterbox at runtime
+- Collect all `piper_phonemize` files — bundles `espeak-ng-data/` (phoneme tables, language dicts) needed by LuxTTS for text-to-phoneme conversion
+- Set `ESPEAK_DATA_PATH` in frozen builds so the espeak-ng C library finds the bundled data instead of looking at `/usr/share/espeak-ng-data/`
+- Collect all `linacodec` files — fixes `inspect.getsource` error in Vocos codec
+- Collect all `zipvoice` files — fixes source code lookup in LuxTTS voice cloning
+- Copy metadata for `requests`, `transformers`, `huggingface-hub`, `tokenizers`, `safetensors`, `tqdm` — fixes `importlib.metadata` lookups in frozen binary
+- Add hidden imports for `chatterbox`, `chatterbox_turbo`, `luxtts`, `zipvoice` backends
+- Add `multiprocessing.freeze_support()` to fix resource_tracker subprocess crash in frozen binary
+- `--noconsole` now only applied on Windows — macOS/Linux need stdout/stderr for Tauri sidecar log capture
+- Hardened `sys.stdout`/`sys.stderr` devnull redirect to test writability, not just `None` check
+
+### Updater
+
+- Fixed updater artifact generation with `v1Compatible` for `tauri-action` signature files
+- Updated `tauri-action` to v0.6 to fix updater JSON and `.sig` generation
+
+### Other Fixes
+
+- Full traceback logging on all backend model loading errors (was just `str(e)` before)
+
+## [0.2.2] - 2026-03-15
+
+- Fix Chatterbox model support in bundled builds
+- Fix LuxTTS/ZipVoice support in bundled builds
+- Auto-update CUDA binary when app version changes
+- CUDA download progress bar
+- Fix server process staying alive on macOS (SIGHUP handling, watchdog grace period)
+- Hide console window when running CUDA binary on Windows
+
+## [0.2.1] - 2026-03-15
+
+Voicebox v0.1.x was a single-engine voice cloning app built around Qwen3-TTS. v0.2.0 is a ground-up rethink: four TTS engines, 23 languages, paralinguistic emotion controls, a post-processing effects pipeline, unlimited generation length, an async generation queue, and support for every major GPU vendor. Plus Docker.
+
+### New TTS Engines
+
+#### Multi-Engine Architecture
+
+Voicebox now runs **four independent TTS engines** behind a thread-safe per-engine backend registry. Switch engines per-generation from a single dropdown — no restart required.
+
+| Engine                      | Languages | Size    | Key Strengths                                 |
+| --------------------------- | --------- | ------- | --------------------------------------------- |
+| **Qwen3-TTS 1.7B**          | 10        | ~3.5 GB | Highest quality, delivery instructions        |
+| **Qwen3-TTS 0.6B**          | 10        | ~1.2 GB | Lighter, faster variant                       |
+| **LuxTTS**                  | English   | ~300 MB | CPU-friendly, 48 kHz output, 150x realtime    |
+| **Chatterbox Multilingual** | 23        | ~3.2 GB | Broadest language coverage, zero-shot cloning |
+| **Chatterbox Turbo**        | English   | ~1.5 GB | 350M params, low latency, paralinguistic tags |
+
+#### Chatterbox Multilingual — 23 Languages ([#257](https://github.com/jamiepine/voicebox/pull/257))
+
+Zero-shot voice cloning in Arabic, Chinese, Danish, Dutch, English, Finnish, French, German, Greek, Hebrew, Hindi, Italian, Japanese, Korean, Malay, Norwegian, Polish, Portuguese, Russian, Spanish, Swahili, Swedish, and Turkish.
+
+#### LuxTTS — Lightweight English TTS ([#254](https://github.com/jamiepine/voicebox/pull/254))
+
+A fast, CPU-friendly English engine. ~300 MB download, 48 kHz output, runs at 150x realtime on CPU.
+
+#### Chatterbox Turbo — Expressive English ([#258](https://github.com/jamiepine/voicebox/pull/258))
+
+A fast 350M-parameter English model with inline paralinguistic tags.
+
+#### Paralinguistic Tags Autocomplete ([#265](https://github.com/jamiepine/voicebox/pull/265))
+
+Type `/` in the text input with Chatterbox Turbo selected to open an autocomplete for **9 expressive tags**: `[laugh]` `[chuckle]` `[gasp]` `[cough]` `[sigh]` `[groan]` `[sniff]` `[shush]` `[clear throat]`
+
+### Generation
+
+#### Unlimited Generation Length — Auto-Chunking ([#266](https://github.com/jamiepine/voicebox/pull/266))
+
+Long text is now automatically split at sentence boundaries, generated per-chunk, and crossfaded back together. Engine-agnostic.
+
+- Auto-chunking limit slider — 100–5,000 chars (default 800)
+- Crossfade slider — 0–200ms (default 50ms)
+- Max text length raised to 50,000 characters
+- Smart splitting respects abbreviations, CJK punctuation, and `[tags]`
+
+#### Asynchronous Generation Queue ([#269](https://github.com/jamiepine/voicebox/pull/269))
+
+Generation is now fully non-blocking. Serial execution queue prevents GPU contention. Real-time SSE status streaming.
+
+#### Generation Versions
+
+Every generation now supports multiple versions with provenance tracking — original, effects versions, takes, source tracking, version pinning in stories, and favorites.
+
+### Post-Processing Effects ([#271](https://github.com/jamiepine/voicebox/pull/271))
+
+A full audio effects system powered by Spotify's `pedalboard` library: Pitch Shift, Reverb, Delay, Chorus/Flanger, Compressor, Gain, High-Pass Filter, Low-Pass Filter. 4 built-in presets, custom presets, per-profile default effects, and live preview.
 
 ### Platform Support

-# Voicebox Offline Mode Fix
-
-## Problem
-Voicebox crashes when generating speech if HuggingFace is unreachable, even when models are fully cached locally.
-
-**Root Cause:**
-- Voicebox downloads `mlx-community/Qwen3-TTS-12Hz-1.7B-Base-bf16` (MLX optimized version)
-- But `mlx_audio.tts.load()` tries to fetch `config.json` from original repo `Qwen/Qwen3-TTS-12Hz-1.7B-Base`
-- This network request fails → server crashes with `RemoteDisconnected`
-
-**Related Issues:**
-- Issue #150: "Internet connection required, even though models are downloaded?"
-- Issue #151: "API Stability Issues: Model Loading Hangs and Server Crashes"
-
-## Solution
-Two-part fix:
-
-### 1. Monkey-patch huggingface_hub (`backend/utils/hf_offline_patch.py`)
-- Intercepts cache lookup functions
-- Forces offline mode early (before mlx_audio imports)
-- Adds debug logging for cache hits/misses
-
-### 2. Symlink original repo to MLX version (`ensure_original_qwen_config_cached()`)
-- When original `Qwen/Qwen3-TTS-12Hz-1.7B-Base` cache doesn't exist
-- But MLX `mlx-community/Qwen3-TTS-12Hz-1.7B-Base-bf16` does exist
-- Creates a symlink so cache lookups succeed
-
-## Files Changed
-- `backend/backends/mlx_backend.py` - Added patch imports at top
-- `backend/utils/hf_offline_patch.py` - New patch module
-
-## Testing
-To test this fix:
-1. Build Voicebox from source: `just build`
-2. Disconnect from internet
-3. Try generating speech
-4. Should work without network requests
-
-## Build Instructions
-
-```bash
-# Install dependencies
-just setup
-
-# Build the app
-just build
-
-# Or build just the server
-just build-server
-```
-
-## Notes
-- The patch is applied automatically when `mlx_backend.py` is imported
-- Set `VOICEBOX_OFFLINE_PATCH=0` to disable the patch
-- The symlink approach works because the config.json is compatible between versions

+title: "Docker Deployment"
+description: "Run Voicebox as a headless server with a web UI using Docker"
+---
+
+## Overview
+
+Voicebox can run as a Docker container with a full web UI -- no desktop app required. This is ideal for headless servers, shared GPU machines, or self-hosted deployments.
+
+## Quick Start
+
+```bash
+git clone https://github.com/jamiepine/voicebox.git
+cd voicebox
+docker compose up
+```
+
+Open [http://localhost:17493](http://localhost:17493) in your browser. The full Voicebox UI is served directly from the backend.
+
+<Callout type="info">
+  The first build takes a few minutes (compiling the frontend, installing Python dependencies). Subsequent starts are fast thanks to Docker layer caching.
+</Callout>
+
+## How It Works
+
+The Docker image uses a 3-stage build:
+
+1. **Frontend** -- builds the React SPA with Bun and Vite
+2. **Backend** -- installs Python dependencies and TTS model packages
+3. **Runtime** -- combines both into a minimal image running the FastAPI server
+
+The backend serves the web UI automatically when the built frontend is present. All API routes work exactly as they do in the desktop app.
+
+## Configuration
+
+### docker-compose.yml
+
+The default `docker-compose.yml` binds to localhost only, mounts persistent volumes for data and model cache, and sets sensible resource limits:
+
+```yaml
+services:
+  voicebox:
+    build: .
+    container_name: voicebox
+    restart: unless-stopped
+    ports:
+      - "127.0.0.1:17493:17493"
+    volumes:
+      - ./output:/app/data/generations
+      - voicebox-data:/app/data
+      - huggingface-cache:/home/voicebox/.cache/huggingface
+    environment:
+      - LOG_LEVEL=info
+    deploy:
+      resources:
+        limits:
+          cpus: '4'
+          memory: 8G
+```
+
+### Exposing to Your Network
+
+By default the container only listens on `127.0.0.1`. To allow other machines on your network to connect, change the port binding:
+
+```yaml
+ports:
+  - "0.0.0.0:17493:17493"
+```
+
+<Callout type="warn">
+  The API has no built-in authentication. Only expose to trusted networks, or put a reverse proxy with auth in front of it.
+</Callout>
+
+### Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `LOG_LEVEL` | `info` | Logging verbosity (`debug`, `info`, `warning`, `error`) |
+| `VOICEBOX_MODELS_DIR` | (HuggingFace cache) | Custom path for model storage |
+| `VOICEBOX_CORS_ORIGINS` | (local origins) | Additional CORS origins, comma-separated |
+
+### Resource Limits
+
+The default compose file limits the container to 4 CPUs and 8GB RAM. Adjust these based on your hardware:
+
+```yaml
+deploy:
+  resources:
+    limits:
+      cpus: '8'
+      memory: 16G
+```
+
+<Callout type="info">
+  TTS model inference is memory-intensive. 8GB is the minimum for running a single engine. 16GB+ is recommended if you want multiple engines loaded simultaneously.
+</Callout>
+
+## Volumes
+
+| Volume | Container Path | Purpose |
+|--------|---------------|---------|
+| `./output` | `/app/data/generations` | Generated audio files (bind-mount, easy access from host) |
+| `voicebox-data` | `/app/data` | Profiles, database, cache |
+| `huggingface-cache` | `/home/voicebox/.cache/huggingface` | Downloaded models (persists across rebuilds) |
+
+The `huggingface-cache` volume is important -- without it, models would be re-downloaded every time the container is rebuilt.
+
+## GPU Acceleration
+
+### NVIDIA GPU (CUDA)
+
+To use your NVIDIA GPU inside the container, install the [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html) and add GPU access to your compose file:
+
+```yaml
+services:
+  voicebox:
+    build: .
+    # ... existing config ...
+    deploy:
+      resources:
+        reservations:
+          devices:
+            - driver: nvidia
+              count: 1
+              capabilities: [gpu]
+```
+
+### AMD GPU (ROCm)
+
+For AMD GPUs, use the ROCm runtime:
+
+```yaml
+services:
+  voicebox:
+    build: .
+    # ... existing config ...
+    devices:
+      - /dev/kfd
+      - /dev/dri
+    group_add:
+      - video
+```
+
+### CPU Only
+
+The default configuration runs on CPU. This works fine but generation will be slower. LuxTTS is the fastest engine on CPU (150x realtime).
+
+## Security
+
+The Docker image follows security best practices:
+
+- **Non-root user** -- the server runs as `voicebox`, not `root`
+- **Localhost binding** -- only accessible from the host machine by default
+- **Health checks** -- automatic restart if the server hangs (`/health` endpoint polled every 30s)
+- **CORS restricted** -- only local origins allowed by default
+
+### Running Behind a Reverse Proxy
+
+For production deployments, put Voicebox behind nginx or Caddy with TLS and authentication:
+
+```nginx
+server {
+    listen 443 ssl;
+    server_name voicebox.example.com;
+
+    ssl_certificate /etc/ssl/certs/voicebox.pem;
+    ssl_certificate_key /etc/ssl/private/voicebox.key;
+
+    auth_basic "Voicebox";
+    auth_basic_user_file /etc/nginx/.htpasswd;
+
+    location / {
+        proxy_pass http://127.0.0.1:17493;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+```
+
+## Troubleshooting
+
+### Container starts but UI shows JSON
+
+If you see `{"message": "voicebox API", ...}` instead of the web UI, the frontend build may have failed during the Docker build. Check the build logs:
+
+```bash
+docker compose build --no-cache
+```
+
+Look for errors in the "Build frontend" stage.
+
+### Models downloading on every restart
+
+Make sure the `huggingface-cache` volume is configured. Without it, the model cache is lost when the container stops:
+
+```yaml
+volumes:
+  - huggingface-cache:/home/voicebox/.cache/huggingface
+```
+
+### Out of memory
+
+TTS models are large. If the container is killed by the OOM killer, increase the memory limit:
+
+```yaml
+deploy:
+  resources:
+    limits:
+      memory: 16G
+```
+
+### Port already in use
+
+```bash
+# Check what's using port 17493
+lsof -i :17493
+
+# Or use a different port
+ports:
+  - "127.0.0.1:8080:17493"
+```
+
+## Prebuilt Images (Coming Soon)
+
+We plan to publish prebuilt Docker images to GitHub Container Registry so you won't need to build locally:
+
+```bash
+# Not available yet — coming in a future release
+docker run -p 17493:17493 ghcr.io/jamiepine/voicebox:latest
+```
+
+The CPU image will be ~3-4 GB (Python + PyTorch + TTS packages). A separate CUDA tag (~6-8 GB) will be available for NVIDIA GPU users. This is normal for ML containers.
+
+For now, use `docker compose up` to build from source as described above.
+
+## Connecting the Desktop App
+
+You can also use the desktop app as a frontend for a Docker-hosted backend. In the desktop app, go to **Settings -> Server**, enable **Remote Mode**, and enter `http://<server-ip>:17493`.
+
+See the [Remote Mode guide](/overview/remote-mode) for details.

+# Code Review: `backend/` Post-Refactor
+
+**Date:** 2026-03-16
+**Scope:** Full review of `backend/` after major refactor
+
+## Overall Assessment
+
+The refactor is well-executed. The codebase follows a clean layered architecture (routes -> services -> backends) with good separation of concerns. The code is readable, the module boundaries are sensible, and the migration strategy is pragmatic for a desktop app. Below are findings organized by severity.
+
+---
+
+## Critical Issues
+
+### 1. Double `init_db()` in bundled entry point
+
+**File:** `server.py:261`
+
+`server.py:261` calls `database.init_db()` explicitly, but `app.py:140` also calls `database.init_db()` inside the `startup` event handler. When running via `server.py`, the database gets initialized twice -- once before uvicorn starts and once during the startup event. This is likely benign (idempotent migrations), but the second call recreates the engine and `SessionLocal`, which could cause subtle issues if any sessions were opened between the two calls.
+
+**Recommendation:** Remove the explicit `init_db()` call in `server.py:260-262` and rely solely on the startup event in `app.py`. The same issue exists in `main.py:38`.
+
+### 2. SSE endpoint holds DB session open indefinitely
+
+**File:** `routes/generations.py:179-212`
+
+The `get_generation_status` SSE endpoint receives a `db` session via `Depends(get_db)` but keeps it open for the lifetime of the SSE stream (polling every 1 second). This ties up a SQLite connection for potentially minutes. With SQLite's single-writer model, this is a contention risk.
+
+**Recommendation:** Open and close a short-lived session on each poll iteration instead of holding one via dependency injection:
+
+```python
+async def event_stream():
+    while True:
+        db = next(get_db())
+        try:
+            gen = db.query(DBGeneration).filter_by(id=generation_id).first()
+            ...
+        finally:
+            db.close()
+        await asyncio.sleep(1)
+```
+
+---
+
+## High Severity
+
+### 3. `_save_retry` creates no version record
+
+**File:** `services/generation.py:201-214`
+
+`_save_retry` writes the audio file but creates no `GenerationVersion` entry. If the generation previously had versions (from an initial generate that failed mid-effects, for example), the retry result won't appear in the versions list. This creates an inconsistency: some generations have versions, retried ones don't.
+
+**Recommendation:** Create a "clean" version in `_save_retry` the same way `_save_generate` does.
+
+### 4. `datetime.utcnow()` is deprecated
+
+**File:** `services/stories.py` and others
+
+`datetime.utcnow()` is deprecated as of Python 3.12 and returns a naive datetime. Used throughout `services/stories.py` (lines 95, 96, 193, 307, 360, 404, 457, 529, 537, 598, 610, 652, 716, 775) and possibly other service files.
+
+**Recommendation:** Replace with `datetime.now(datetime.UTC)` or `datetime.now(timezone.utc)`.
+
+### 5. `list_stories` N+1 query
+
+**File:** `services/stories.py:122-132`
+
+`list_stories` issues one `COUNT(*)` query per story inside a loop. For N stories, that's N+1 queries.
+
+**Recommendation:** Use a subquery or a single aggregated query:
+
+```python
+from sqlalchemy import func
+counts = dict(
+    db.query(DBStoryItem.story_id, func.count(DBStoryItem.id))
+    .group_by(DBStoryItem.story_id)
+    .all()
+)
+```
+
+---
+
+## Medium Severity
+
+### 6. `create_story` queries item count immediately after creation
+
+**File:** `services/stories.py:103`
+
+Line 103 queries the item count for a story that was just created -- it will always be 0. This is wasted I/O.
+
+### 7. Bare `except Exception` with silent `pass`
+
+**File:** `routes/generations.py:69-70`
+
+When parsing a profile's stored `effects_chain` JSON, exceptions are silently swallowed. A corrupt JSON blob would result in no effects being applied with no logging.
+
+**Recommendation:** Log the exception at warning level.
+
+### 8. `update_story_item_times` uses `generation_id` as key
+
+**File:** `services/stories.py:643-649`
+
+`item_map` is keyed by `generation_id`, but the same generation can appear in a story multiple times (via split/duplicate). This would cause key collisions, and only the last item per generation_id would be updatable.
+
+**Recommendation:** Key by `item_id` instead, and change the `StoryItemUpdateTime` model to use `item_id`.
+
+### 9. Thread safety gap in `get_stt_backend`
+
+**File:** `backends/__init__.py:499-520`
+
+`get_stt_backend()` uses no locking (unlike `get_tts_backend_for_engine` which uses `_tts_backends_lock`). A race condition could create duplicate STT backend instances.
+
+**Recommendation:** Add a lock or use the same double-checked locking pattern.
+
+### 10. Unused `_tts_backend` global
+
+**File:** `backends/__init__.py:156`
+
+`_tts_backend` is declared but never read or written outside of `reset_backends()`. All TTS access goes through `_tts_backends` dict. Dead code.
+
+### 11. `trim_story_item` returns `None` for validation errors
+
+**File:** `services/stories.py:448`
+
+Returning `None` for "item not found" and "invalid trim values" is ambiguous. The route handler can't distinguish between a 404 and a 400 response.
+
+**Recommendation:** Raise specific exceptions (e.g., `ValueError` for invalid trim) so the route can return the appropriate HTTP status.
+
+### 12. `load_engine_model` calls different method names
+
+**File:** `backends/__init__.py:340-346`
+
+For Qwen, it calls `load_model_async(model_size)`. For others, it calls `load_model()` with no arguments. But the `TTSBackend` protocol defines `load_model(self, model_size: str)`. This means the protocol signature doesn't match actual usage for either path.
+
+**Recommendation:** Align the protocol definition with actual backend implementations, or add `load_model_async` to the protocol.
+
+---
+
+## Low Severity / Style
+
+### 13. Inconsistent `async` usage in services
+
+Functions like `create_story`, `list_stories`, etc. in `services/stories.py` are `async def` but contain no `await` expressions. They do synchronous SQLAlchemy I/O. While this works (the functions are awaitable), it's misleading -- these will block the event loop during DB access.
+
+This is a known tradeoff with synchronous SQLAlchemy + FastAPI, and acceptable for a single-user desktop app with SQLite, but worth noting for documentation.
+
+### 14. `getattr(item, "version_id", None)` pattern
+
+**File:** `services/stories.py:57, 504, 524, etc.`
+
+Multiple places use `getattr(item, "version_id", None)` on a DB model that has `version_id` as a declared column (from migrations). After the migration runs, this is always a real attribute. The defensive `getattr` is cargo-culted.
+
+**Recommendation:** Access `item.version_id` directly. If the column is missing, the ORM will raise a clear error.
+
+### 15. `reorder_story_items` ignores trim values
+
+**File:** `services/stories.py:707`
+
+When recalculating timecodes, it uses the full `generation.duration` rather than the effective (trimmed) duration. Trimmed items will have larger gaps than intended.
+
+### 16. Module-level `import torch` in `app.py:44`
+
+`import torch` at module level in `app.py` means torch loads on every import of the app module. This is intentional (AMD env vars must be set first), but the comment on line 38 should mention that this is why the import is here and not at the top.
+
+### 17. f-strings in logging in `server.py`
+
+`server.py` uses f-strings in logging calls (e.g., lines 63-66, 252, 256, 264). This evaluates the string even when the log level is filtered out. The rest of the codebase correctly uses `%s` style (e.g., `app.py:131`).
+
+---
+
+## Architecture Observations (Not Issues)
+
+- **Clean layered design**: routes -> services -> backends with Pydantic models as the API contract.
+- **Backend abstraction** with `Protocol` classes and a config registry is a solid pattern.
+- **Serial generation queue** (`task_queue.py`) is simple and effective for single-GPU serialization.
+- **Migration approach** is pragmatic for the use case. The idempotent, check-then-act pattern is reliable.
+- **The `generation.py` refactor** (collapsing three closures into `run_generation` with a mode parameter) is a clear improvement.
+
+---
+
+## Summary
+
+| Severity | Count |
+|----------|-------|
+| Critical | 2 |
+| High | 3 |
+| Medium | 7 |
+| Low/Style | 5 |
+
+The refactor achieved its goals: clear module boundaries, reduced duplication (especially in `generation.py`), and a well-organized backend abstraction. The critical items (double init_db and SSE session leak) should be addressed first, followed by the version consistency issue in retry and the N+1 query.
