fix: force offline mode when loading cached models (Qwen TTS & Whisper)

Qwen TTS and Whisper Base make network calls to HuggingFace even when
model weights are fully cached locally, because from_pretrained()
defaults to local_files_only=False. This causes failures for offline
users.

Add a reusable force_offline_if_cached() context manager that sets
HF_HUB_OFFLINE=1 during model loading when is_model_cached() is True.
Applied to all four affected load paths:

- PyTorchTTSBackend (Qwen TTS)
- PyTorchSTTBackend (Whisper)
- MLXTTSBackend (refactored from inline implementation)
- MLXSTTBackend (previously unprotected)

Closes #82

+description: Use this skill to add a new TTS engine to Voicebox. It walks through dependency research, backend implementation, frontend wiring, PyInstaller bundling, and frozen-build testing. Always start with Phase 0 (dependency audit) before writing any code.
+---
+
+# Add TTS Engine
+
+## Goal
+
+Integrate a new text-to-speech engine into Voicebox end-to-end: dependency research, backend protocol implementation, frontend UI wiring, PyInstaller bundling, and frozen-build verification. The user should only need to test the final build locally.
+
+## Reference Doc
+
+The full phased guide lives at `docs/content/docs/developer/tts-engines.mdx`. **Read this file in its entirety before starting.** It contains:
+
+- Phase 0: Dependency research (mandatory before writing code)
+- Phase 1: Backend implementation (`TTSBackend` protocol)
+- Phase 2: Route and service integration (usually zero changes)
+- Phase 3: Frontend integration (5 files)
+- Phase 4: Dependencies (`requirements.txt`, justfile, CI, Docker)
+- Phase 5: PyInstaller bundling (`build_binary.py` + `server.py`)
+- Phase 6: Common upstream workarounds
+- Implementation checklist (gate between phases)
+
+## Workflow
+
+### 1. Read the guide
+
+```bash
+# Read the full TTS engines doc
+cat docs/content/docs/developer/tts-engines.mdx
+```
+
+Internalize all phases, especially Phase 0 and Phase 5. The v0.2.3 release was three patch releases because Phase 0 was skipped.
+
+### 2. Dependency research (Phase 0)
+
+Clone the model library into a temporary directory and audit it. Do NOT skip this.
+
+```bash
+mkdir /tmp/engine-research && cd /tmp/engine-research
+git clone <model-library-url>
+```
+
+Run the grep searches from Phase 0.2 in the guide against the cloned source and its transitive dependencies. Produce a written dependency audit covering:
+
+1. PyPI vs non-PyPI packages
+2. PyInstaller directives needed (`--collect-all`, `--copy-metadata`, `--hidden-import`)
+3. Runtime data files that must be bundled
+4. Native library paths that need env var overrides in frozen builds
+5. Monkey-patches needed (`torch.load`, float64, MPS, HF token)
+6. Sample rate
+7. Model download method (`from_pretrained` vs `snapshot_download` + `from_local`)
+
+Test model loading and generation on CPU in the throwaway venv before proceeding.
+
+### 3. Implement (Phases 1–4)
+
+Follow the guide's phases in order. Key files to modify:
+
+**Backend (Phase 1):**
+- Create `backend/backends/<engine>_backend.py`
+- Register in `backend/backends/__init__.py` (ModelConfig + TTS_ENGINES + factory)
+- Update regex in `backend/models.py`
+
+**Frontend (Phase 3):**
+- `app/src/lib/api/types.ts` — engine union type
+- `app/src/lib/constants/languages.ts` — ENGINE_LANGUAGES
+- `app/src/components/Generation/EngineModelSelector.tsx` — ENGINE_OPTIONS, ENGINE_DESCRIPTIONS
+- `app/src/lib/hooks/useGenerationForm.ts` — Zod schema, model-name mapping
+- `app/src/components/ServerSettings/ModelManagement.tsx` — MODEL_DESCRIPTIONS
+
+**Dependencies (Phase 4):**
+- `backend/requirements.txt`
+- `justfile` (setup-python, setup-python-release targets)
+- `.github/workflows/release.yml`
+- `Dockerfile` (if applicable)
+
+### 4. PyInstaller bundling (Phase 5)
+
+Register the engine in `backend/build_binary.py`:
+- `--hidden-import` for the backend module and model package
+- `--collect-all` for packages using `inspect.getsource`, shipping data files, or native libraries
+- `--copy-metadata` for packages using `importlib.metadata`
+
+If the engine has native data paths, add `os.environ.setdefault()` in `backend/server.py` inside the `if getattr(sys, 'frozen', False):` block.
+
+### 5. Verify in dev mode
+
+```bash
+just dev
+```
+
+Test the full chain: model download → load → generate → voice cloning.
+
+### 6. Use the checklist
+
+Walk through the Implementation Checklist at the bottom of `tts-engines.mdx`. Every item must be checked before handing the build to the user.
+
+## Key Lessons (from v0.2.3)
+
+These are the most common failure modes. Phase 0 research catches all of them:
+
+| Pattern | Symptom in Frozen Build | Fix |
+|---------|------------------------|-----|
+| `@typechecked` / `inspect.getsource()` | "could not get source code" | `--collect-all <package>` |
+| Package ships pretrained model files | `FileNotFoundError` for `.pth.tar`, `.yaml` | `--collect-all <package>` |
+| C library with hardcoded system paths | `FileNotFoundError` for `/usr/share/...` | `--collect-all` + env var in `server.py` |
+| `importlib.metadata.version()` | "No package metadata found" | `--copy-metadata <package>` |
+| `torch.load` without `map_location` | CUDA device not available on CPU build | Monkey-patch `torch.load` |
+| `torch.from_numpy` on float64 data | dtype mismatch RuntimeError | Cast to `.float()` |
+| `token=True` in HF download calls | Auth failure without stored HF token | Use `snapshot_download(token=None)` + `from_local()` |
+
+## Notes
+
+- The route and service layers have zero per-engine dispatch points. `main.py` requires zero changes.
+- The model config registry in `backends/__init__.py` handles all dispatch automatically.
+- Use `get_torch_device()` and `model_load_progress()` from `backends/base.py` — don't reimplement device detection or progress tracking.
+- Always test with a **clean HuggingFace cache** (no pre-downloaded models from dev).
+- Do NOT push or create a release. Hand the build to the user for local testing.

+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.

+---
+
+# 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)`

 ## [Unreleased]
 
-### Added
+## [0.3.0] - 2026-03-17
-- **Makefile** - Comprehensive development workflow automation with commands for setup, development, building, testing, and code quality checks
-  - Includes Python version detection and compatibility warnings
-  - Self-documenting help system with `make help`
-  - Colored output for better readability
-  - Supports parallel development server execution
 
-### Changed
+This release rewrites the backend into a modular architecture, overhauls the settings UI into routed sub-pages, fixes audio player freezing, migrates documentation to Fumadocs, and ships a batch of bug fixes targeting the most-reported issues from the tracker.
-- **README** - Added Makefile reference and updated Quick Start with Makefile-based setup instructions alongside manual setup
 
----
+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, settings have been split into dedicated routed pages with server logs, a changelog viewer, and an about page. The audio player no longer freezes mid-playback, and model loading status is now visible in the UI. Seven user-reported bugs have been fixed, including server crashes during sample uploads, generation list staleness, cryptic error messages, and CUDA support for RTX 50-series GPUs.
 
-## [Unreleased - Planned]
+### Settings Overhaul ([#294](https://github.com/jamiepine/voicebox/pull/294))

-- Plugin architecture
 
----
+### 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
 
+### Documentation Rewrite ([#288](https://github.com/jamiepine/voicebox/pull/288))
+- Migrated docs site from Mintlify to Fumadocs (Next.js-based)
+- Rewrote introduction and root page with content from README
+- Added "Edit on GitHub" links and last-updated timestamps on all pages

+- Sidebar groups now expand by default; root redirects to `/docs`
+- Added OG image metadata and `/og` preview page
+
+### UI & Frontend
+- Added model loading status indicator and effects preset dropdown ([3187344](https://github.com/jamiepine/voicebox/commit/3187344))
+- Fixed take-label race condition during regeneration
+- Added accessible focus styling to select component
+- Softened select focus indicator opacity
+- Addressed 4 critical and 12 major issues from CodeRabbit review
+
+### Bug Fixes ([#295](https://github.com/jamiepine/voicebox/pull/295))
+- Fixed sample uploads crashing the server — audio decoding now runs in a thread pool instead of blocking the async event loop ([#278](https://github.com/jamiepine/voicebox/issues/278))
+- Fixed generation list not updating when a generation completes — switched to `refetchQueries` for reliable cache busting, added SSE error fallback, and page reset on completion ([#231](https://github.com/jamiepine/voicebox/issues/231))
+- Fixed error toasts showing `[object Object]` instead of the actual error message ([#290](https://github.com/jamiepine/voicebox/issues/290))
+- Added Whisper model selection (`base`, `small`, `medium`, `large`, `turbo`) and expanded language support to the `/transcribe` endpoint ([#233](https://github.com/jamiepine/voicebox/issues/233))
+- Upgraded CUDA backend build from cu121 to cu126 for RTX 50-series (Blackwell) GPU support ([#289](https://github.com/jamiepine/voicebox/issues/289))

+- Fixed Docker frontend build and cleaned up Docker docs
+- Fixed macOS download links to use `.dmg` instead of `.app.tar.gz`
+- Added dynamic download redirect routes to landing site
+
+### Release Tooling
+- Added `draft-release-notes` and `release-bump` agent skills
+- Wired CI release workflow to extract notes from `CHANGELOG.md` for GitHub Releases
+- Backfilled changelog with all historical releases
+
+## [0.2.3] - 2026-03-15
+
+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
+
+- **Windows Support** ([#272](https://github.com/jamiepine/voicebox/pull/272)) — Full Windows support with CUDA GPU detection
+- **Linux** ([#262](https://github.com/jamiepine/voicebox/pull/262)) — AMD ROCm, NVIDIA GBM fix, WebKitGTK mic access (build from source)
+- **NVIDIA CUDA Backend Swap** ([#252](https://github.com/jamiepine/voicebox/pull/252)) — Download and swap in CUDA backend from within the app
+- **Intel Arc (XPU) and DirectML** — PyTorch backend supports Intel Arc and DirectML
+- **Docker + Web Deployment** ([#161](https://github.com/jamiepine/voicebox/pull/161)) — 3-stage build, non-root runtime, health checks
+- **Whisper Turbo** — Added `openai/whisper-large-v3-turbo` as a transcription model option
+
+### Model Management ([#268](https://github.com/jamiepine/voicebox/pull/268))
+
+Per-model unload, custom models directory, model folder migration, download cancel/clear UI ([#238](https://github.com/jamiepine/voicebox/pull/238)), restructured settings UI.
+
+### Security & Reliability
+
+- CORS hardening ([#88](https://github.com/jamiepine/voicebox/pull/88))
+- Network access toggle ([#133](https://github.com/jamiepine/voicebox/pull/133))

+- **[Tauri Prerequisites](https://v2.tauri.app/start/prerequisites)** - Tauri-specific system dependencies (varies by OS).
 
 - **Git** - Version control
 
 ### Development Setup
 
-**Using the Makefile (recommended for macOS/Linux):** Run `make setup` to install all dependencies, then `make dev` to start development servers. See `make help` for all available commands.
+Install [just](https://github.com/casey/just) (`brew install just`, `cargo install just`, or `winget install Casey.Just`), then:
 
-**Manual setup (required for Windows):**
+```bash
+git clone https://github.com/YOUR_USERNAME/voicebox.git
+cd voicebox
 
-1. **Fork and clone the repository**
+just setup   # creates venv, installs Python + JS deps
-   ```bash
+just dev     # starts backend + desktop app
-   git clone https://github.com/YOUR_USERNAME/voicebox.git
+```
-   cd voicebox
-   ```
 
-2. **Install JavaScript dependencies**
+`just setup` handles everything automatically, including:
-   ```bash
+- Creating a Python virtual environment
-   bun install
+- Installing Python dependencies (with CUDA PyTorch on Windows if an NVIDIA GPU is detected)
-   ```
+- Installing MLX dependencies on Apple Silicon
-   This installs dependencies for:
+- Installing JavaScript dependencies
-   - `app/` - Shared React frontend
-   - `tauri/` - Tauri desktop wrapper
-   - `web/` - Web deployment wrapper
 
-3. **Set up Python backend**
+`just dev` starts the backend and desktop app together. If a backend is already running (e.g. from `just dev-backend` in another terminal), it detects it and only starts the frontend.
-   ```bash
-   cd backend
-   
-   # Create virtual environment
-   python -m venv venv
-   
-   # Activate virtual environment
-   source venv/bin/activate  # On macOS/Linux
-   # or
-   venv\Scripts\activate  # On Windows
-   
-   # Install Python dependencies
-   pip install -r requirements.txt
-   
-   # Install MLX dependencies (Apple Silicon only - for faster inference)
-   # On Apple Silicon, this enables native Metal acceleration
-   if [[ $(uname -m) == "arm64" ]]; then
-     pip install -r requirements-mlx.txt
-   fi
-   
-   # Install Qwen3-TTS (required for voice synthesis)
-   pip install git+https://github.com/QwenLM/Qwen3-TTS.git
-   ```
 
-4. **Start development servers**
+Other useful commands:
 
-   Development requires two terminals: one for the Python backend, one for the Tauri app.
+```bash
+just dev-web       # backend + web app (no Tauri/Rust build)
+just dev-backend   # backend only
+just dev-frontend  # Tauri app only (backend must be running)
+just kill          # stop all dev processes
+just clean-all     # nuke everything and start fresh
+just --list        # see all available commands
+```
 
-   **Terminal 1: Backend server** (start this first)
+> **Note:** In dev mode, the app connects to a manually-started Python server.
-   ```bash
+> The bundled server binary is only used in production builds.
-   cd backend
-   source venv/bin/activate  # Activate venv if not already active
-   bun run dev:server
-   # Or manually: uvicorn main:app --reload --port 17493
-   ```
-   Backend will be available at `http://localhost:17493`
 
-   **Terminal 2: Desktop app**
+#### Windows Notes
-   ```bash
-   bun run dev
-   ```
-   This will:
-   - Create a placeholder sidecar binary (for Tauri compilation)
-   - Start Vite dev server on port 5173
-   - Launch Tauri window pointing to localhost:5173
-   - Connect to the Python server you started in Terminal 1
-   - Enable hot reload
 
-   > **Note:** In dev mode, the app connects to your manually-started Python server.
+The justfile works natively on Windows via PowerShell. No WSL or Git Bash required. On Windows with an NVIDIA GPU, `just setup` automatically installs CUDA-enabled PyTorch for GPU acceleration.
-   > The bundled server binary is only used in production builds.
-
-   **Optional: Web app**
-   ```bash
-   bun run dev:web
-   ```
-   Web app will be available at `http://localhost:5174`

-**Build everything (recommended):**
+**Build production app:**
+
 ```bash
-bun run build
+just build        # Build CPU server binary + Tauri installer
 ```
-This automatically:
+
-1. Builds the Python server binary (`./scripts/build-server.sh`)
+On Windows, to build with CUDA support for local testing:
-2. Builds the Tauri desktop app (`cd tauri && bun run tauri build`)
+
+```bash
+just build-local  # Build CPU + CUDA server binaries + Tauri installer
+```
+
+This builds the CPU sidecar (bundled with the app), the CUDA binary (placed in `%APPDATA%/com.voicebox.app/backends/` for runtime GPU switching), and the installable Tauri app.
 
 Creates platform-specific installers (`.dmg`, `.msi`, `.AppImage`) in `tauri/src-tauri/target/release/bundle/`.
 
-**Note:** The build process detects your platform and includes the appropriate backend (MLX for Apple Silicon, PyTorch for others).
+**Individual build targets:**
 
-**Build server binary only:**
 ```bash
-bun run build:server
+just build-server       # CPU server binary only
-# or
+just build-server-cuda  # CUDA server binary only (Windows)

 ## What is Voicebox?
 
-Voicebox is a **local-first voice cloning studio** with DAW-like features for professional voice synthesis. Think of it as the **Ollama for voice** — download models, clone voices, and generate speech entirely on your machine.
+Voicebox is a **local-first voice cloning studio** — a free and open-source alternative to ElevenLabs. Clone voices from a few seconds of audio, generate speech in 23 languages across 5 TTS engines, apply post-processing effects, and compose multi-voice projects with a timeline editor.
-
-Unlike cloud services that lock your voice data behind subscriptions, Voicebox gives you:
 
 - **Complete privacy** — models and voice data stay on your machine
-- **Professional tools** — multi-track timeline editor, audio trimming, conversation mixing
+- **5 TTS engines** — Qwen3-TTS, LuxTTS, Chatterbox Multilingual, Chatterbox Turbo, and HumeAI TADA
-- **Model flexibility** — currently powered by Qwen3-TTS, with support for XTTS, Bark, and other models coming soon
+- **23 languages** — from English to Arabic, Japanese, Hindi, Swahili, and more
-- **API-first** — use the desktop app or integrate voice synthesis into your own projects
+- **Post-processing effects** — pitch shift, reverb, delay, chorus, compression, and filters
+- **Expressive speech** — paralinguistic tags like `[laugh]`, `[sigh]`, `[gasp]` via Chatterbox Turbo
+- **Unlimited length** — auto-chunking with crossfade for scripts, articles, and chapters
+- **Stories editor** — multi-track timeline for conversations, podcasts, and narratives
+- **API-first** — REST API for integrating voice synthesis into your own projects
 - **Native performance** — built with Tauri (Rust), not Electron
-- **Super fast on Mac** — MLX backend with native Metal acceleration for 4-5x faster inference on Apple Silicon
+- **Runs everywhere** — macOS (MLX/Metal), Windows (CUDA), Linux, AMD ROCm, Intel Arc, Docker
-
-Download a voice model, clone any voice from a few seconds of audio, and compose multi-voice projects with studio-grade editing tools. No Python install required, no cloud dependency, no limits.

 ## Features
 
-### Voice Cloning with Qwen3-TTS
+### Multi-Engine Voice Cloning
 
-Powered by Alibaba's **Qwen3-TTS** — a breakthrough model that achieves near-perfect voice cloning from just a few seconds of audio.
+Five TTS engines with different strengths, switchable per-generation:
 
-- **Instant cloning** — Upload a sample, get a voice profile
+| Engine                      | Languages | Strengths                                                                                                                                |
-- **High fidelity** — Natural prosody, emotion, and cadence
+| --------------------------- | --------- | ---------------------------------------------------------------------------------------------------------------------------------------- |
-- **Multi-language** — English, Chinese, and more coming
+| **Qwen3-TTS** (0.6B / 1.7B) | 10        | High-quality multilingual cloning, delivery instructions ("speak slowly", "whisper")                                                     |
-- **Lightning fast on Mac** — MLX backend leverages Apple Silicon's Neural Engine for super fast generation

+
+### Emotions & Paralinguistic Tags
+
+Type `/` in the text input to insert expressive tags that the model synthesizes inline with speech (Chatterbox Turbo):
+
+`[laugh]` `[chuckle]` `[gasp]` `[cough]` `[sigh]` `[groan]` `[sniff]` `[shush]` `[clear throat]`
+
+### Post-Processing Effects
+
+8 audio effects powered by Spotify's `pedalboard` library. Apply after generation, preview in real time, build reusable presets.
+
+| Effect           | Description                                   |
+| ---------------- | --------------------------------------------- |
+| Pitch Shift      | Up or down by up to 12 semitones              |
+| Reverb           | Configurable room size, damping, wet/dry mix  |
+| Delay            | Echo with adjustable time, feedback, and mix  |
+| Chorus / Flanger | Modulated delay for metallic or lush textures |
+| Compressor       | Dynamic range compression                     |
+| Gain             | Volume adjustment (-40 to +40 dB)             |
+| High-Pass Filter | Remove low frequencies                        |
+| Low-Pass Filter  | Remove high frequencies                       |
+
+Ships with 4 built-in presets (Robotic, Radio, Echo Chamber, Deep Voice) and supports custom presets. Effects can be assigned per-profile as defaults.
+
+### Unlimited Generation Length
+
+Text is automatically split at sentence boundaries and each chunk is generated independently, then crossfaded together. Works with all engines.
+
+- Configurable auto-chunking limit (100–5,000 chars)
+- Crossfade slider (0–200ms) for smooth transitions
+- Max text length: 50,000 characters
+- Smart splitting respects abbreviations, CJK punctuation, and `[tags]`
+
+### Generation Versions
+
+Every generation supports multiple versions with provenance tracking:
+
+- **Original** — clean TTS output, always preserved
+- **Effects versions** — apply different effects chains from any source version
+- **Takes** — regenerate with a new seed for variation
+- **Source tracking** — each version records its lineage
+- **Favorites** — star generations for quick access
+
+### Async Generation Queue
+
+Generation is non-blocking. Submit and immediately start typing the next one.
+
+- Serial execution queue prevents GPU contention
+- Real-time SSE status streaming
+- Failed generations can be retried
+- Stale generations from crashes auto-recover on startup

 See [CONTRIBUTING.md](CONTRIBUTING.md) for detailed setup and contribution guidelines.
 
-**Using the Makefile (recommended):** Run `make help` to see all available commands for setup, development, building, and testing.
-
 ### Quick Start
 
-**With Makefile (Unix/macOS/Linux):**
-
 ```bash
-# Clone the repo
+git clone https://github.com/jamiepine/voicebox.git
-git clone https://github.com/voicebox-sh/voicebox.git
 cd voicebox
 
-# Setup everything
+just setup   # creates Python venv, installs all deps
-make setup
+just dev     # starts backend + desktop app
-
-# Start development
-make dev
 ```
 
-**Manual setup (all platforms):**
+Install [just](https://github.com/casey/just): `brew install just` or `cargo install just`. Run `just --list` to see all commands.
+
+**Prerequisites:** [Bun](https://bun.sh), [Rust](https://rustup.rs), [Python 3.11+](https://python.org), [Tauri Prerequisites](https://v2.tauri.app/start/prerequisites/), and [Xcode](https://developer.apple.com/xcode/) on macOS.
+
+### Building Locally
 
 ```bash
-# Clone the repo
+just build          # Build CPU server binary + Tauri app
-git clone https://github.com/voicebox-sh/voicebox.git
+just build-local    # (Windows) Build CPU + CUDA server binaries + Tauri app
-cd voicebox
-
-# Install dependencies
-bun install
-
-# Install Python dependencies
-cd backend && pip install -r requirements.txt && cd ..
-
-# Start development
-bun run dev
 ```
 
-**Prerequisites:** [Bun](https://bun.sh), [Rust](https://rustup.rs), [Python 3.11+](https://python.org). 
+### Adding New Voice Models
 
-**Performance:** 
+The multi-engine architecture makes adding new TTS engines straightforward. A [step-by-step guide](docs/content/docs/developer/tts-engines.mdx) covers the full process: dependency research, backend protocol implementation, frontend wiring, and PyInstaller bundling.
-- **Apple Silicon (M1/M2/M3)**: Uses MLX backend with native Metal acceleration for 4-5x faster inference
+
-- **Windows/Linux/Intel Mac**: Uses PyTorch backend (CUDA GPU recommended, CPU supported but slower)
+The guide is optimized for AI coding agents. An [agent skill](.agents/skills/add-tts-engine/SKILL.md) can pick up a model name and handle the entire integration autonomously — you just test the build locally.

-### Backend Selection
+### Request flow
-
-Voicebox automatically selects the best backend based on platform:
-
-- **Apple Silicon (M1/M2/M3)**: Uses MLX backend with native Metal acceleration (4-5x faster)
-- **Windows/Linux/Intel Mac**: Uses PyTorch backend (CUDA GPU if available, CPU fallback)
-
-The backend is detected at runtime via `platform_detect.py`. Both backends implement the same interface, so the API remains consistent across platforms.

 ```
 
-## Setup
+Route handlers are intentionally thin. They validate input, delegate to a service function, and format the response. All business logic lives in `services/`.
 
-### 1. Install Dependencies
+### Key modules
+
+**services/generation.py** -- Single `run_generation()` function that handles all three generation modes (generate, retry, regenerate). Manages model loading, voice prompt creation, chunked inference, normalization, effects, and version persistence.
+
+**services/task_queue.py** -- Serial generation queue. Ensures only one GPU inference runs at a time. Background tasks are tracked to prevent garbage collection.
+
+**backends/__init__.py** -- Protocol definitions (`TTSBackend`, `STTBackend`), model config registry, and factory functions. Adding a new engine means implementing the protocol and registering a config entry.
+
+**backends/base.py** -- Shared utilities used across all engine implementations: HuggingFace cache checks, device detection, voice prompt combination, progress tracking.
+
+**database/** -- SQLAlchemy ORM models with a re-exporting `__init__.py` for backward compatibility. Migrations run automatically on startup.
+
+### Backend selection
+
+The server detects the best inference backend at startup:
+
+| Platform | Backend | Acceleration |
+|----------|---------|-------------|
+| macOS (Apple Silicon) | MLX | Metal / Neural Engine |
+| Windows / Linux (NVIDIA) | PyTorch | CUDA |
+| Linux (AMD) | PyTorch | ROCm |
+| Intel Arc | PyTorch | IPEX / XPU |
+| Windows (any GPU) | PyTorch | DirectML |
+| Any | PyTorch | CPU fallback |
+
+Detection is handled by `utils/platform_detect.py`. Both backends implement the same `TTSBackend` protocol, so the API layer is engine-agnostic.
+
+## API
+
+90 endpoints organized by domain. Full interactive documentation available at `http://localhost:17493/docs` when the server is running.
+
+| Domain | Prefix | Description |
+|--------|--------|-------------|
+| Health | `/`, `/health` | Server status, GPU info, filesystem checks |
+| Profiles | `/profiles` | Voice profile CRUD, samples, avatars, import/export |
+| Channels | `/channels` | Audio channel management and voice assignment |
+| Generation | `/generate` | TTS generation, retry, regenerate, status SSE |
+| History | `/history` | Generation history, search, favorites, export |
+| Transcription | `/transcribe` | Whisper-based audio-to-text |
+| Stories | `/stories` | Multi-track timeline editor, audio export |
+| Effects | `/effects` | Effect presets, preview, version management |
+| Audio | `/audio`, `/samples` | Audio file serving |
+| Models | `/models` | Load, unload, download, migrate, status |
+| Tasks | `/tasks`, `/cache` | Active task tracking, cache management |
+| CUDA | `/backend/cuda-*` | CUDA binary download and management |
+
+### Quick examples
 
 ```bash
-pip install -r requirements.txt
+# Generate speech
-```
+curl -X POST http://localhost:17493/generate \
-
-**Note:** On Apple Silicon, also install MLX dependencies for faster inference:
-```bash
-pip install -r requirements-mlx.txt
-```
-
-### 2. Download Models (Automatic)
-
-The Qwen3-TTS models are automatically downloaded from HuggingFace Hub on first use, similar to how Whisper models work.
-
-**No manual download required!** The models will be cached locally after the first download.
-
-Available models:
-- **1.7B** (recommended): `Qwen/Qwen3-TTS-12Hz-1.7B-Base` (~4GB)
-- **0.6B** (faster): `Qwen/Qwen3-TTS-12Hz-0.6B-Base` (~2GB)
-
-**Note:** The first generation will take longer as the model downloads. Subsequent generations will use the cached model.
-
-#### Manual Download (Optional)
-
-If you prefer to download models manually or have limited internet during runtime:
-
-```bash
-# Install huggingface-cli
-pip install huggingface_hub
-
-# Download 1.7B model
-huggingface-cli download Qwen/Qwen3-TTS-12Hz-1.7B-Base
-
-# Or use Python
-python -c "from huggingface_hub import snapshot_download; snapshot_download('Qwen/Qwen3-TTS-12Hz-1.7B-Base')"
-```
-
-Models are cached in `~/.cache/huggingface/hub/` by default.
-
-### 4. Run Server
-
-```bash
-# Development (local only)
-python -m backend.main
-
-# Production (allow remote access)
-python -m backend.main --host 0.0.0.0 --port 8000
-```
-
-## Usage Examples
-
-### Creating a Voice Profile
-
-```bash
-# 1. Create profile
-curl -X POST http://localhost:8000/profiles \
   -H "Content-Type: application/json" \
-  -d '{"name": "My Voice", "language": "en"}'
+  -d '{"text": "Hello world", "profile_id": "...", "language": "en"}'
 
-# Response: {"id": "abc-123", ...}
+# List profiles
+curl http://localhost:17493/profiles
 
-# 2. Add sample
+# Stream generation status (SSE)
-curl -X POST http://localhost:8000/profiles/abc-123/samples \
+curl http://localhost:17493/generate/{id}/status
-  -F "[email protected]" \
-  -F "reference_text=This is my voice sample"
 ```
 
-### Generating Speech
+## Data directory
+
+```
+{data_dir}/
+  voicebox.db             # SQLite database
+  profiles/{id}/          # Voice samples per profile
+  generations/            # Generated audio files
+  cache/                  # Voice prompt cache (memory + disk)
+  backends/               # Downloaded CUDA binary (if applicable)
+```
+
+Default location is the OS-specific app data directory. Override with `--data-dir` or the `VOICEBOX_DATA_DIR` environment variable.
+
+## Code quality
+
+Linting and formatting are enforced by [ruff](https://docs.astral.sh/ruff/), configured in `pyproject.toml`. See `STYLE_GUIDE.md` for conventions.
 
 ```bash
-curl -X POST http://localhost:8000/generate \
+just check-python       # lint + format check
-  -H "Content-Type: application/json" \
+just fix-python         # auto-fix lint issues + reformat
-  -d '{
+just test               # run pytest
-    "profile_id": "abc-123",
-    "text": "Hello, this is a test.",
-    "language": "en",
-    "seed": 42
-  }'
-
-# Response: {"id": "gen-456", "audio_path": "/path/to/audio.wav", ...}
-
-# Download audio
-curl http://localhost:8000/audio/gen-456 -o output.wav
 ```
 
-### Transcribing Audio
+## Dependencies
 
-```bash
+Runtime dependencies are in `requirements.txt`. macOS-only MLX dependencies are in `requirements-mlx.txt`. Dev tools (ruff, pytest) are installed automatically by `just setup-python`.
-curl -X POST http://localhost:8000/transcribe \
-  -F "[email protected]" \
-  -F "language=en"
-
-# Response: {"text": "Transcribed text", "duration": 5.5}
-```
-
-## Advanced Features
-
-### Multi-Sample Profiles
-
-Add multiple samples to a profile for better quality:
-
-```bash
-# Add first sample
-curl -X POST http://localhost:8000/profiles/abc-123/samples \
-  -F "[email protected]" \
-  -F "reference_text=First sample"
-
-# Add second sample
-curl -X POST http://localhost:8000/profiles/abc-123/samples \
-  -F "[email protected]" \
-  -F "reference_text=Second sample"
-
-# Generation will automatically combine all samples
-```
-
-### Voice Prompt Caching
-
-Voice prompts are automatically cached for faster generation:
-- First generation: ~5-10 seconds (creates prompt)
-- Subsequent generations: ~1-2 seconds (uses cached prompt)
-
-Cache is stored in `data/cache/` and persists across server restarts.
-
-### VRAM Management
-
-Models are lazy-loaded and can be manually unloaded:
-
-```bash
-# Unload TTS model
-curl -X POST http://localhost:8000/models/unload
-
-# Load specific model size
-curl -X POST "http://localhost:8000/models/load?model_size=0.6B"
-```
-
-## Error Handling
-
-All endpoints return proper HTTP status codes:
-
-- `200 OK`: Success
-- `400 Bad Request`: Invalid input
-- `404 Not Found`: Resource not found
-- `500 Internal Server Error`: Server error
-
-Error responses include details:
-
-```json
-{
-  "detail": "Profile not found"
-}
-```
-
-## Performance Tips
-
-1. **Use multi-sample profiles** - Better quality than single sample
-2. **Let caching work** - Voice prompts are cached automatically
-3. **Use 0.6B model on CPU** - Faster than 1.7B with acceptable quality
-4. **Use 1.7B model on GPU** - Best quality, still fast
-5. **Unload Whisper after transcription** - Frees VRAM for TTS
-

+# Python Style Guide
+
+Target: **Python 3.12+** | Formatter/Linter: **Ruff** | Config: `backend/pyproject.toml`
+
+This guide codifies the conventions used across the backend, and prescribes the target style for code written during the refactor (Phases 3-6). Existing code should be migrated incrementally -- don't reformat entire files in unrelated PRs.
+
+---
+
+## Formatting
+
+Enforced by `ruff format` (Black-compatible).
+
+- **Line length**: 120 characters.
+- **Indent**: 4 spaces. No tabs.
+- **Trailing commas**: Required on multi-line function signatures, arguments, collections.
+- **Quotes**: Double quotes (`"`) for strings. Single quotes are acceptable in f-string expressions and dict keys inside f-strings where avoiding escapes improves readability.
+
+Run: `ruff format backend/`
+
+---
+
+## Imports
+
+Enforced by ruff's `isort` rules (rule set `I`).
+
+**Grouping** -- three blocks separated by a blank line:
+
+```python
+import asyncio                          # 1. stdlib
+from pathlib import Path
+
+import numpy as np                      # 2. third-party
+from fastapi import APIRouter, HTTPException
+from sqlalchemy.orm import Session
+
+from backend.config import get_data_dir  # 3. local (absolute)
+from .database import get_db            #    or relative
+```
+
+**Rules:**
+- Within the `backend` package, use **relative imports** for sibling/child modules: `from .database import get_db`, `from ..utils.audio import load_audio`.
+- Absolute imports are fine for top-level references from entry points (`main.py`, `server.py`).
+- Never use wildcard imports (`from module import *`).
+- One import per line for `from X import Y` when there are 4+ names; below that, comma-separated is fine.
+- **Lazy imports** are acceptable for heavy dependencies (torch, transformers, mlx) inside functions to reduce startup time. Add a comment: `# lazy: heavy import`.
+
+---
+
+## Type Annotations
+
+Python 3.12 means we use **built-in generics and union syntax natively**. No `from __future__ import annotations`, no `typing.List`/`typing.Dict`.
+
+```python
+# Yes
+def process(items: list[str], config: dict[str, int] | None = None) -> tuple[int, str]: ...
+
+# No
+from typing import List, Dict, Optional, Tuple
+def process(items: List[str], config: Optional[Dict[str, int]] = None) -> Tuple[int, str]: ...
+```
+
+**What to annotate:**
+- All public function signatures (parameters + return type).
+- Private functions: parameters at minimum; return type encouraged.
+- Module-level variables: only when the type isn't obvious from the assignment.
+- Route handlers: parameters are annotated via FastAPI's dependency injection. Add explicit `-> SomeResponse` return types when the route doesn't use `response_model`.
+
+**Imports from `typing` that are still needed** (no built-in equivalent):
+`Literal`, `TypeAlias`, `Protocol`, `runtime_checkable`, `Callable`, `Any`, `ClassVar`, `TypeVar`, `overload`, `TYPE_CHECKING`.
+
+Use `collections.abc` for abstract types: `Sequence`, `Mapping`, `Iterable`, `Iterator`, `Generator`.
+
+---
+
+## Naming
+
+| Thing | Convention | Example |
+|-------|-----------|---------|

+
+## Docstrings
+
+**Google style**. Required on all public functions, classes, and modules.
+
+```python
+def combine_voice_prompts(
+    profile_dir: Path,
+    *,
+    target_sr: int = 24000,
+) -> tuple[np.ndarray, int]:
+    """Load and concatenate all voice prompt files for a profile.
+
+    Reads .wav/.mp3/.flac files from the profile directory, resamples to
+    the target sample rate, normalizes, and concatenates into a single array.
+
+    Args:
+        profile_dir: Path to the voice profile directory containing audio files.
+        target_sr: Target sample rate for the output. Defaults to 24000.
+
+    Returns:
+        Tuple of (concatenated audio array, sample rate).
+
+    Raises:
+        FileNotFoundError: If profile_dir does not exist.
+        ValueError: If no valid audio files are found.
+    """
+```
+
+**Short form** is fine for simple functions:
+
+```python
+def get_db_path() -> Path:
+    """Get the path to the SQLite database file."""
+```
+
+**When to skip**: Private helpers under ~5 lines where the name and signature make intent obvious.
+
+**Module docstrings**: A single sentence at the top of every file describing its purpose.
+
+```python
+"""Voice profile CRUD operations."""
+```
+
+---
+
+## Comments
+
+Comments explain **why**, not **what**. If the code needs a comment to explain what it does, the code should be rewritten to be clearer. The exceptions are non-obvious performance choices, external constraints, and concurrency/race-condition reasoning -- those always deserve a comment.
+
+### No section dividers
+
+Do not use ASCII dividers to create visual sections in files:
+
+```python
+# No -- any of these:
+# ============================================
+# GENERATION ENDPOINTS
+# ============================================
+
+# ---------------------------------------------------------------------------
+# Device detection
+# ---------------------------------------------------------------------------
+
+# --- Load model --------------------------------------------------
+```
+
+If a file needs section dividers to be navigable, the file is too long. Split it into modules. Within a function, if you need labeled sections to follow the logic, extract those sections into named functions.
+
+### Inline comments
+
+Inline comments (end-of-line) are fine when they add information the code can't express:
+
+```python
+# Yes -- explains a non-obvious constraint or gives context:
+audio, sr = load_audio(path, sr=24000)  # Qwen expects 24kHz mono
+_generation_queue: asyncio.Queue = None  # type: ignore  # initialized at startup
+"tauri://localhost",         # Tauri webview (macOS)
+
+# No -- restates the code:
+# Check if profile name already exists
+existing = db.query(DBVoiceProfile).filter_by(name=data.name).first()
+
+# Delete from database
+db.delete(sample)
+
+# Update fields
+profile.name = data.name
+```
+
+Delete comments that narrate what the next line of code obviously does. If the function name, variable name, or method call already communicates intent, the comment is noise.
+
+### Block comments
+
+Use block comments for **why** explanations -- constraints, workarounds, non-obvious decisions:
+
+```python
+# PyInstaller + multiprocessing: child processes re-execute the frozen binary
+# with internal arguments. freeze_support() handles this and exits early.
+multiprocessing.freeze_support()
+
+# Mark any stale "generating" records as failed -- these are leftovers
+# from a previous process that was killed mid-generation.
+db.query(Generation).filter_by(status="generating").update({"status": "failed"})
+```
+
+Keep block comments tight. Two to three lines is normal. If you need a paragraph, it probably belongs in the docstring or a design doc.
+
+### Linter/type-checker suppression
+
+Always add a reason after `noqa` and `type: ignore`:
+
+```python
+import intel_extension_for_pytorch  # noqa: F401 -- side-effect import enables XPU
+_queue: asyncio.Queue = None  # type: ignore[assignment]  # initialized at startup
+```
+
+Bare `# noqa` or `# type: ignore` with no explanation are not allowed.
+
+### TODO / FIXME
+
+Use sparingly. Every `TODO` must include a brief description of what needs doing. Don't use them as a substitute for tracking work properly:
+
+```python
+# TODO: replace with async SQLAlchemy once CRUD modules are migrated (Phase 5)
+result = await asyncio.to_thread(profiles.get_profile, profile_id, db)
+```
+
+Never commit `HACK`, `XXX`, or `FIXME` -- fix the problem or file an issue.
+
+### Commented-out code
+
+Delete it. That's what git is for. If you need to document that something was intentionally removed, a short tombstone comment is acceptable:
+
+```python
+# Removed config.json-only check -- too lenient, doesn't confirm weights exist.
+```
+
+---
+
+## Error Handling
+
+The refactor is standardizing on a **two-layer pattern**:
+
+### 1. Domain layer -- raise plain exceptions
+
+CRUD modules and services raise `ValueError`, `FileNotFoundError`, or (post-refactor) custom exceptions defined in `backend/errors.py`:
+
+```python
+# backend/errors.py  (to be created in Phase 4)
+class NotFoundError(Exception):
+    """Raised when a requested resource does not exist."""
+
+class ConflictError(Exception):
+    """Raised on uniqueness constraint violations."""
+```
+
+```python
+# In a service or CRUD module:
+raise NotFoundError(f"Profile {profile_id} not found")
+```
+
+### 2. Route layer -- translate to HTTPException
+
+Route handlers catch domain exceptions and convert:
+
+```python
+@router.post("/profiles")
+async def create_profile(data: VoiceProfileCreate, db: Session = Depends(get_db)):
+    try:
+        return await profiles.create_profile(data, db)
+    except ConflictError as e:
+        raise HTTPException(status_code=409, detail=str(e))
+```
+
+**Background tasks** catch `Exception` broadly, log with `logger.exception()`, and update the task status to `"failed"`.
+
+**Never**: silently swallow exceptions, use bare `except:`, or catch `BaseException`.
+
+---
+
+## Async
+
+### Rules for the refactor
+
+1. **Don't declare `async def` unless the function awaits something.** Several service modules still declare `async def` without awaiting -- these should be migrated to sync functions with `asyncio.to_thread()` at the route layer, or to real async SQLAlchemy.
+2. **CPU-bound work** (audio processing, numpy operations) goes through `asyncio.to_thread()`:
+   ```python
+   audio, sr = await asyncio.to_thread(load_audio, source_path)
+   ```
+3. **GPU-bound TTS inference** is serialized through the generation queue (`services/task_queue.py`). Never call a backend's `generate()` directly from a route handler.
+4. **Fire-and-forget tasks**: use `asyncio.create_task()` and track the task reference to prevent garbage collection:
+   ```python
+   task = asyncio.create_task(some_coro())
+   _background_tasks.add(task)
+   task.add_done_callback(_background_tasks.discard)
+   ```
+
+---
+
+## Logging
+
+Use the `logging` module. Not `print()`.
+
+```python
+import logging
+
+logger = logging.getLogger(__name__)
+
+logger.info("Loading model %s on %s", model_name, device)
+logger.warning("Cache miss for %s, downloading", repo_id)
+logger.exception("Generation %s failed")  # logs traceback automatically
+```
+
+**Rules:**
+- Use `%s`-style placeholders in log calls (not f-strings). This avoids formatting the string if the log level is filtered out.
+- Use `logger.exception()` inside `except` blocks -- it captures the traceback.
+- Logger name should be `__name__` (yields `backend.utils.audio`, etc.).
+- Existing `print()` calls should be migrated to logging as files are touched during the refactor.
+
+---
+
+## Constants
+
+- Define at **module level** in the file where they're primarily used.
+- Use `UPPER_SNAKE_CASE`.
+- Shared/cross-cutting constants (sample rates, file size limits, CORS origins) go in `backend/config.py` after Phase 6 consolidation.
+- Magic numbers in function bodies should be extracted to named constants:
+  ```python
+  # No
+  if len(audio) > 24000 * 60 * 10:
+
+  # Yes
+  MAX_AUDIO_DURATION_SAMPLES = SAMPLE_RATE * 60 * 10
+  if len(audio) > MAX_AUDIO_DURATION_SAMPLES:
+  ```
+
+---
+
+## Function Signatures
+
+- **Keyword-only arguments** (after `*`) for functions with 3+ parameters, especially when several share the same type:
+  ```python
+  def is_model_cached(
+      hf_repo: str,
+      *,
+      weight_extensions: tuple[str, ...] = (".safetensors", ".bin"),
+      required_files: list[str] | None = None,
+  ) -> bool:
+  ```
+- Parameters on **separate lines** when the signature exceeds ~100 characters or has 3+ params.
+- **Trailing comma** after the last parameter in multi-line signatures.
+- Default values inline with the parameter.
+
+---
+
+## String Formatting
+
+- **f-strings** for runtime string construction.
+- **`%s`-style** for `logging` calls (lazy evaluation).
+- **`.format()`**: avoid; f-strings are preferred.
+
+---
+
+## Testing
+
+Framework: **pytest** with `pytest-asyncio`.
+
+- Test files: `test_<module>.py` in `backend/tests/`.
+- Use `conftest.py` for shared fixtures (db sessions, test client, mock backends).
+- Group related tests in classes: `class TestProfileCRUD:`.
+- Use `@pytest.mark.asyncio` for async tests.
+- Use `@pytest.mark.parametrize` to reduce repetition.
+- Manual integration scripts stay in `tests/` but are clearly marked (filename prefix `manual_` or documented in `tests/README.md`).
+
+---
+
+## Project Layout
+
+```
+backend/
+  app.py              # FastAPI app factory, CORS, lifecycle events
+  main.py             # Entry point (imports app, runs uvicorn)
+  config.py           # Data directory paths
+  models.py           # Pydantic request/response schemas
+  server.py           # Tauri sidecar launcher, parent-pid watchdog
+  routes/             # Thin HTTP handlers (validation, delegation, response formatting)
+  services/           # Business logic, CRUD, orchestration
+  backends/           # TTS/STT engine implementations
+  database/           # ORM models, session management, migrations, seeds
+  utils/              # Shared utilities (audio, effects, caching, progress)
+  tests/              # pytest suite
+```
+
+---
+
+## Ruff Adoption
+
+`pyproject.toml` configures ruff for linting and formatting. Run:
+
+```bash
+# Lint (check)
+ruff check backend/
+
+# Lint (auto-fix)
+ruff check backend/ --fix
+
+# Format
+ruff format backend/
+```
+
+Introduce ruff fixes file-by-file as you touch them. Don't run `--fix` across the entire codebase in one shot -- that creates unreviewable diffs.
