chore: bump version to 1.4.9 [skip ci]

The workflow_dispatch input was accessed as github.event.inputs.tag
which can be empty depending on the Gitea runner. Now tries both
inputs.tag (modern syntax) and github.event.inputs.tag as fallback,
with a final fallback to the latest matching git tag.

Also switched Windows Determine-tag steps from PowerShell to bash
(via Git Bash) for consistency with the other platforms.

 ## Project Overview
 
-Local Transcription is a desktop application for real-time speech-to-text transcription designed for streamers. It uses Whisper models (via faster-whisper) to transcribe audio locally with optional multi-user server synchronization.
+Local Transcription is a cross-platform desktop application for real-time speech-to-text transcription designed for streamers. It supports local Whisper models and cloud-based Deepgram transcription, with OBS browser source integration and optional multi-user sync.
+
+**Architecture:** Two-process model — a Tauri v2 shell (Svelte 5 frontend) communicates with a headless Python backend (sidecar) via REST API and WebSocket.
 
 **Key Features:**
-- Standalone desktop GUI (PySide6/Qt)
-- Local transcription with CPU/GPU support
-- Built-in web server for OBS browser source integration
-- Optional Node.js-based multi-user server for syncing transcriptions across users
-- Noise suppression and Voice Activity Detection (VAD)
-- Cross-platform builds (Linux/Windows) with PyInstaller
+- Cross-platform desktop app (Windows, macOS, Linux) via Tauri v2 + Svelte 5
+- Headless Python backend with FastAPI control API
+- Dual transcription modes: local Whisper or cloud Deepgram (managed/BYOK)
+- Built-in web server for OBS browser source at `http://localhost:8080`
+- Optional multi-user sync via Node.js server
+- CUDA, MPS (Apple Silicon), and CPU support
+- Auto-updates, custom fonts, configurable colors
+
+> **Legacy GUI:** The original PySide6/Qt GUI (`main.py`, `gui/`) still works during the transition. New features should target the Tauri frontend and headless backend.

-## Architecture
+## Architecture Details
 
-### Audio Processing Pipeline
+### Communication: Tauri <-> Python Backend
 
-1. **Audio Capture** ([client/audio_capture.py](client/audio_capture.py))
-   - Captures audio from microphone/system using sounddevice
-   - Handles automatic sample rate detection and resampling
-   - Uses chunking with overlap for better transcription quality
-   - Default: 3-second chunks with 0.5s overlap
+The Svelte frontend connects to the Python backend via two channels:
 
-2. **Noise Suppression** ([client/noise_suppression.py](client/noise_suppression.py))
-   - Applies noisereduce for background noise reduction
-   - Voice Activity Detection (VAD) using webrtcvad
-   - Skips silent segments to improve performance
+**REST API** (on port 8081 by default):
+- `GET /api/status` — app state, device info, version
+- `POST /api/start` / `POST /api/stop` — transcription control
+- `GET /api/config` / `PUT /api/config` — read/write settings (dot-notation keys)
+- `GET /api/audio-devices` / `GET /api/compute-devices` — device enumeration
+- `POST /api/reload-engine` — reload with new model/device
+- `GET /api/transcriptions` / `POST /api/clear` — transcript management
+- `POST /api/save-file` — write text to a file path
+- `GET /api/check-update` / `POST /api/skip-version` — update management
+- `POST /api/login` / `POST /api/register` / `GET /api/balance` — managed mode proxy
 
-3. **Transcription** ([client/transcription_engine.py](client/transcription_engine.py))
-   - Uses faster-whisper for efficient inference
-   - Supports CPU, CUDA, and Apple MPS (Mac)
-   - Models: tiny, base, small, medium, large
-   - Thread-safe model loading with locks
+**WebSocket** `/ws/control`:
+- Pushes real-time events: `state_changed`, `transcription`, `preview`, `error`, `credits_low`
+- Client sends keepalive pings
 
-4. **Display** ([gui/main_window_qt.py](gui/main_window_qt.py))
-   - PySide6/Qt-based desktop GUI
-   - Real-time transcription display with scrolling
-   - Settings panel with live updates (no restart needed)
+The OBS display server runs separately on port 8080 (`GET /` for HTML, `WebSocket /ws` for transcriptions).
 
-### Web Server Architecture
+### Backend Process Lifecycle
 
-**Local Web Server** ([server/web_display.py](server/web_display.py))
-- Always runs when GUI starts (port 8080 by default)
-- FastAPI with WebSocket for real-time updates
-- Used for OBS browser source integration
-- Single-user (displays only local transcriptions)
+1. `main_headless.py` starts, acquires instance lock, creates `AppController`
+2. `AppController.initialize()` starts the OBS web server (port 8080) and engine init thread
+3. `APIServer` wraps the controller with FastAPI routes, runs on port 8081
+4. Backend prints `{"event": "ready", "port": 8080}` to stdout for Tauri to discover
+5. On shutdown: engine stopped, web server stopped, lock released
 
-**Multi-User Server** (Optional - for syncing across multiple users)
+### Headless Backend vs Legacy GUI
 
-**Node.js WebSocket Server** ([server/nodejs/](server/nodejs/)) - **RECOMMENDED**
-- Real-time WebSocket support (< 100ms latency)
-- Handles 100+ concurrent users
-- Easy deployment to VPS/cloud hosting (Railway, Heroku, DigitalOcean, or any VPS)
-- Configurable display options via URL parameters:
-  - `timestamps=true/false` - Show/hide timestamps
-  - `maxlines=50` - Maximum visible lines (prevents scroll bars in OBS)
-  - `fontsize=16` - Font size in pixels
-  - `fontfamily=Arial` - Font family
-  - `fade=10` - Seconds before text fades (0 = never)
+The `AppController` class (`backend/app_controller.py`) extracts all orchestration logic from `gui/main_window_qt.py` into a Qt-free class. The mapping:
 
-See [server/nodejs/README.md](server/nodejs/README.md) for deployment instructions
+| Legacy (MainWindow) | Headless (AppController) |
+|---------------------|--------------------------|
+| `_initialize_components()` | `_initialize_engine()` |
+| `_start_transcription()` | `start_transcription()` |
+| `_stop_transcription()` | `stop_transcription()` |
+| `_on_settings_saved()` | `apply_settings()` |
+| `_reload_engine()` | `reload_engine()` |
+| `_start_web_server_if_enabled()` | `_start_web_server()` |
+| `_start_server_sync()` | `_start_server_sync()` |
+| Qt signals | Callbacks (`on_state_changed`, `on_transcription`, etc.) |
 
-### Configuration System
+### Threading Model (Headless)
 
-- Config stored at `~/.local-transcription/config.yaml`
-- Managed by [client/config.py](client/config.py)
-- Settings apply immediately without restart (except model changes)
-- YAML format with nested keys (e.g., `transcription.model`)
+- Main thread: Uvicorn (FastAPI) event loop
+- Engine init thread: Downloads models, initializes VAD
+- Web server thread: Separate asyncio loop for OBS display
+- Audio capture: Runs in engine callback threads
+- All results flow through `AppController` callbacks -> `APIServer` WebSocket broadcast
 
-### Device Management
+### Svelte Frontend
 
-- [client/device_utils.py](client/device_utils.py) handles CPU/GPU detection
-- Auto-detects CUDA, MPS (Mac), or falls back to CPU
-- Compute types: float32 (best quality), float16 (GPU), int8 (fastest)
-- Thread-safe device selection
+Uses Svelte 5 runes throughout (`$state`, `$derived`, `$effect`, `$props`). No Svelte 4 patterns.
 
-## Key Implementation Details
+**Stores** (`src/lib/stores/`):
+- `backend.ts` — WebSocket connection + REST helpers (`apiGet`, `apiPost`, `apiPut`), auto-reconnect
+- `config.ts` — fetches/updates config from backend API
+- `transcriptions.ts` — manages transcript list, listens for `CustomEvent`s from backend store
 
-### PyInstaller Build Configuration
+**Key patterns:**
+- Backend store dispatches `CustomEvent`s on `window` for cross-store communication
+- Settings component collects all changed values into a `Record<string, any>` with dot-notation keys, sends via `PUT /api/config`
+- Controls use Tauri dialog plugin for native file save, falls back to blob download
 
-- [local-transcription.spec](local-transcription.spec) controls build
-- UPX compression enabled for smaller executables
-- Hidden imports required for PySide6, faster-whisper, torch
-- Console mode enabled by default (set `console=False` to hide)
+## CI/CD
 
-### Threading Model
+Eight Gitea Actions workflows in `.gitea/workflows/`, split into coordinators and per-OS builders:
 
-- Main thread: Qt GUI event loop
-- Audio thread: Captures and processes audio chunks
-- Web server thread: Runs FastAPI server
-- Transcription: Runs in callback thread from audio capture
-- All transcription results communicated via Qt signals
+**App release (Tauri):**
+- **`release.yml`**: Coordinator. Triggers on push to `main`. Auto-bumps version in package.json/tauri.conf.json/Cargo.toml/version.py, commits, tags `v{VERSION}`, creates Gitea release.
+- **`build-app-linux.yml`**: Triggers on `v*` tag push or `workflow_dispatch`. Builds Tauri app, uploads `.deb`/`.rpm`/`.AppImage`.
+- **`build-app-windows.yml`**: Triggers on `v*` tag push or `workflow_dispatch`. Builds Tauri app, uploads `.msi`/`*-setup.exe`.
+- **`build-app-macos.yml`**: Triggers on `v*` tag push or `workflow_dispatch`. Builds Tauri app, uploads `.dmg`.
 
-### Server Sync (Optional Multi-User Feature)
+**Sidecar release (Python backend):**
+- **`sidecar-release.yml`**: Coordinator. Triggers on push to `main` with changes in `client/`, `server/`, `backend/`, `pyproject.toml`, or `local-transcription-headless.spec`. Bumps version in pyproject.toml/version.py, tags `sidecar-v{VERSION}`, creates Gitea release.
+- **`build-sidecar-linux.yml`**: Triggers on `sidecar-v*` tag push or `workflow_dispatch`. Builds CUDA + CPU sidecars via PyInstaller.
+- **`build-sidecar-windows.yml`**: Triggers on `sidecar-v*` tag push or `workflow_dispatch`. Builds CUDA + CPU sidecars via PyInstaller.
+- **`build-sidecar-macos.yml`**: Triggers on `sidecar-v*` tag push or `workflow_dispatch`. Builds CPU-only sidecar via PyInstaller.
 
-- [client/server_sync.py](client/server_sync.py) handles server communication
-- Toggle in Settings: "Enable Server Sync"
-- Sends transcriptions to Node.js server via HTTP POST
-- Real-time updates via WebSocket to display page
-- Per-speaker font support (Web-Safe, Google Fonts, Custom uploads)
-- Falls back gracefully if server unavailable
+All per-OS build workflows can be re-run independently via `workflow_dispatch` with an optional `tag` input. All require a `BUILD_TOKEN` secret (Gitea API token with release write access).
 
 ## Common Patterns
 
 ### Adding a New Setting
 
-1. Add to [config/default_config.yaml](config/default_config.yaml)
-2. Update [client/config.py](client/config.py) if validation needed
-3. Add UI control in [gui/settings_dialog_qt.py](gui/settings_dialog_qt.py)
-4. Apply setting in relevant component (no restart if possible)
-5. Emit signal to update display if needed
+1. Add default to [config/default_config.yaml](config/default_config.yaml)
+2. Add UI control in [src/lib/components/Settings.svelte](src/lib/components/Settings.svelte)
+3. Ensure the setting is included in the save handler's config update
+4. Apply in `AppController.apply_settings()` or the relevant component
+5. For legacy GUI: also update [gui/settings_dialog_qt.py](gui/settings_dialog_qt.py)
+
+### Adding a New API Endpoint
+
+1. Add route in [backend/api_server.py](backend/api_server.py) `_setup_routes()`
+2. Add supporting logic in [backend/app_controller.py](backend/app_controller.py) if needed
+3. Call from Svelte via `backendStore.apiGet/apiPost/apiPut`
 
 ### Modifying Transcription Display
 
-- Local GUI: [gui/transcription_display_qt.py](gui/transcription_display_qt.py)
-- Local web display (OBS): [server/web_display.py](server/web_display.py) (HTML in `_get_html()`)
+- Tauri UI: [src/lib/components/TranscriptionDisplay.svelte](src/lib/components/TranscriptionDisplay.svelte)
+- OBS display: [server/web_display.py](server/web_display.py) (HTML in `_get_html()`)
 - Multi-user display: [server/nodejs/server.js](server/nodejs/server.js) (display page in `/display` route)
 
-### Adding a New Model Size
-
-- Update [client/transcription_engine.py](client/transcription_engine.py)
-- Add to model selector in [gui/settings_dialog_qt.py](gui/settings_dialog_qt.py)
-- Update CLI argument choices in [main_cli.py](main_cli.py)
-
 ## Dependencies
 
-**Core:**
-- `faster-whisper`: Optimized Whisper inference
-- `torch`: ML framework (CUDA-enabled via special index)
-- `PySide6`: Qt6 bindings for GUI
-- `sounddevice`: Cross-platform audio I/O
-- `noisereduce`, `webrtcvad`: Audio preprocessing
-
-**Web Server:**
-- `fastapi`, `uvicorn`: Web server and ASGI
-- `websockets`: Real-time communication
-
-**Build:**
-- `pyinstaller`: Create standalone executables
-- `uv`: Fast package manager
-
-**PyTorch CUDA Index:**
-- Configured in [pyproject.toml](pyproject.toml) under `[[tool.uv.index]]`
-- Uses PyTorch's custom wheel repository for CUDA builds
-- Automatically installed with `uv sync` when using CUDA build scripts
+**Frontend:** Tauri v2, Svelte 5, Vite, TypeScript
+**Backend:** Python 3.9+, FastAPI, Uvicorn, RealtimeSTT, faster-whisper, PyTorch (CUDA), sounddevice
+**Build:** PyInstaller (sidecar), Tauri CLI (app), uv (Python packages)
+**CI:** Gitea Actions with platform-specific runners
 
 ## Platform-Specific Notes
 
 ### Linux
-- Uses PulseAudio/ALSA for audio
-- Build scripts use bash (`.sh` files)
-- Executable: `dist/LocalTranscription/LocalTranscription`
+- Tauri needs: `libgtk-3-dev`, `libwebkit2gtk-4.1-dev`, `libappindicator3-dev`, `librsvg2-dev`, `patchelf`
+- Audio: PulseAudio/ALSA via sounddevice
 
 ### Windows
-- Uses Windows Audio/WASAPI
-- Build scripts use batch (`.bat` files)
-- Executable: `dist\LocalTranscription\LocalTranscription.exe`
-- Requires Visual C++ Redistributable on target systems
+- Tauri needs: WebView2 (usually pre-installed on Windows 10+)
+- Audio: WASAPI via sounddevice
 
-### Cross-Building
-- **Cannot cross-compile** - must build on target platform
-- CI/CD should use platform-specific runners
-
-## Troubleshooting
-
-### Model Loading Issues
-- Models download to `~/.cache/huggingface/`
-- First run requires internet connection
-- Check disk space (models: 75MB-3GB depending on size)
-
-### Audio Device Issues
-- Run `uv run python main_cli.py --list-devices`
-- Check permissions (microphone access)
-- Try different device indices in settings
-
-### GPU Not Detected
-- Run `uv run python check_cuda.py`
-- Install CUDA drivers (not CUDA toolkit - bundled in build)
-- Verify PyTorch sees GPU: `python -c "import torch; print(torch.cuda.is_available())"`
-
-### Web Server Port Conflicts
-- Default port: 8080
-- Change in [gui/main_window_qt.py](gui/main_window_qt.py) or config
-- Use `lsof -i :8080` (Linux) or `netstat -ano | findstr :8080` (Windows)
-
-## OBS Integration
-
-### Local Display (Single User)
-1. Start Local Transcription app
-2. In OBS: Add "Browser" source
-3. URL: `http://localhost:8080`
-4. Set dimensions (e.g., 1920x300)
-
-### Multi-User Display (Node.js Server)
-1. Deploy Node.js server (see [server/nodejs/README.md](server/nodejs/README.md))
-2. Each user configures Server URL: `http://your-server:3000/api/send`
-3. Enter same room name and passphrase
-4. In OBS: Add "Browser" source
-5. URL: `http://your-server:3000/display?room=ROOM&fade=10&timestamps=true&maxlines=50&fontsize=16`
-6. Customize URL parameters as needed:
-   - `timestamps=false` - Hide timestamps
-   - `maxlines=30` - Show max 30 lines (prevents scroll bars)
-   - `fontsize=18` - Larger font
-   - `fontfamily=Courier` - Different font
-
-## Performance Optimization
-
-**For Real-Time Transcription:**
-- Use `tiny` or `base` model (faster)
-- Enable GPU if available (5-10x faster)
-- Increase chunk_duration for better accuracy (higher latency)
-- Decrease chunk_duration for lower latency (less context)
-- Enable VAD to skip silent audio
-
-**For Build Size Reduction:**
-- Don't bundle models (download on demand)
-- Use CPU-only build if no GPU users
-- Enable UPX compression (already in spec)
-
-## Phase Status
-
-- ✅ **Phase 1**: Standalone desktop application (complete)
-- ✅ **Web Server**: Local OBS integration (complete)
-- ✅ **Builds**: PyInstaller executables (complete)
-- ✅ **Phase 2**: Multi-user Node.js server (complete, optional)
-- ⏸️ **Phase 3+**: Advanced features (see [NEXT_STEPS.md](NEXT_STEPS.md))
+### macOS
+- Tauri needs: Xcode Command Line Tools
+- Audio: CoreAudio via sounddevice
+- GPU: MPS (Apple Silicon) detected by `device_utils.py`
+- `Info.plist` must include `NSMicrophoneUsageDescription` for mic access
+- No CUDA builds — CPU/MPS only

-- **Cross-Platform**: Builds available for Windows and Linux
+
+## Architecture
+
+The application uses a two-process architecture:
+
+1. **Tauri Shell** (Svelte 5 frontend) — lightweight native window (~50MB) rendering the UI
+2. **Python Backend** (sidecar) — headless process running transcription, audio capture, and the OBS web server
+
+The Tauri frontend communicates with the Python backend via REST API and WebSocket, following the same pattern as [voice-to-notes](https://repo.anhonesthost.net/MacroPad/voice-to-notes).
+
+```
+Tauri App (user launches this)
+  └─ Spawns Python backend as sidecar
+       ├─ FastAPI REST API (control endpoints)
+       ├─ WebSocket /ws/control (real-time state + transcriptions)
+       ├─ OBS web display at http://localhost:8080
+       └─ Transcription engine (Whisper or Deepgram)
+```
+
+> **Legacy GUI**: The original PySide6/Qt desktop GUI (`main.py`) still works alongside the new Tauri frontend during the transition period.

+## CI/CD
+
+Two Gitea Actions workflows in `.gitea/workflows/`:
+
+| Workflow | Trigger | Produces |
+|----------|---------|----------|
+| `release.yml` | Push to `main` | Tauri app installers for all platforms |
+| `build-sidecar.yml` | Changes to `client/`, `server/`, `backend/`, or `pyproject.toml` | Python sidecar zips (CUDA + CPU) |
+
+Both workflows require a `BUILD_TOKEN` secret in the repo settings (Gitea API token with release write access).
+
+### Release Artifacts
+
+| Platform | App Installer | Sidecar (CUDA) | Sidecar (CPU) |
+|----------|--------------|----------------|---------------|
+| Linux x86_64 | `.deb`, `.rpm`, `.AppImage` | `sidecar-linux-x86_64-cuda.zip` | `sidecar-linux-x86_64-cpu.zip` |
