+fluxo-rs is a high-performance system metrics daemon and client designed specifically for Waybar. It replaces standard shell scripts with a compiled Rust binary that collects data via a background polling loop and serves it over a Unix socket.
 
-## Description
+## Key Features
 
-The project follows a client-server architecture:
+- **Asynchronous Architecture**: Built on **Tokio**, the daemon handles concurrent IPC requests and background tasks with zero latency and minimal CPU overhead.
-- **Daemon**: Handles heavy lifting (polling cpu, memory, network, gpu) and stores state in memory.
+- **Native Library Integrations**: 
-- **Client**: A thin cli wrapper that connects to the daemon's socket to retrieve formatted json for waybar.
+    - **Audio**: Direct `libpulse` integration for event-driven, instant volume and device updates.
-
+    - **Bluetooth**: Native `bluer` integration for robust device monitoring.
-This approach eliminates process spawning overhead and temporary file locking, resulting in near-zero cpu usage for custom modules.
+    - **Pixel Buds Pro**: Custom native RPC implementation for real-time battery and ANC control.
-
+    - **Network**: Native `nix` and `/proc` inspection for high-speed interface monitoring.
-## Features
+    - **Hyprland**: Direct IPC Unix socket communication for gamemode and animation status.
-
+- **Circuit Breaker (Failsafe)**: Automatically detects failing modules and enters a "Cool down" state to prevent resource waste and log spam.
-- **Ultra-lightweight**: Background polling is highly optimized (e.g., O(1) process counting).
+- **Multi-threaded Polling**: Decoupled subsystem threads ensure that a hang in one system (e.g., a slow GPU probe) never freezes your entire bar.
-- **Jitter-free**: Uses zero-width sentinels and figure spaces to prevent waybar from trimming padding.
-- **Configurable**: Fully customizable output formats via toml config.
-- **Interactive Menus**: Integrated support for selecting items (like Bluetooth devices) via external menus (e.g., Rofi, Wofi, Fuzzel).
-- **Live Reload**: Configuration can be reloaded without restarting the daemon.
-- **Multi-vendor GPU**: Native support for intel (igpu), amd, and nvidia.

 ## Setup
 
-1. Build the project:
+1. **Build**: `cargo build --release`
-   ```bash
+2. **Configure**: Create `~/.config/fluxo/config.toml` (see `example.config.toml`).
-   cd fluxo-rs
+3. **Daemon**: Start `fluxo-rs daemon`. It's recommended to run this as a systemd user service.
-   cargo build --release
-   ```
 
-2. Start the daemon:
+## Waybar Configuration
-   ```bash
-   # Starts the daemon using the default config path (~/.config/fluxo/config.toml)
-   ./target/release/fluxo-rs daemon &
 
-   # Or provide a custom path
+To achieve zero-latency updates, use **Waybar Signals**:
-   ./target/release/fluxo-rs daemon --config /path/to/your/config.toml &
-   ```
 
-3. Configuration:
+```jsonc
-   Create `~/.config/fluxo/config.toml` (see `example.config.toml` for all default options).
+"custom/audio": {
-
+    "exec": "fluxo vol",
-4. Waybar configuration (`config.jsonc`):
+    "return-type": "json",
-   ```json
+    "interval": 5,
-   "custom/cpu": {
+    "signal": 8,
-       "exec": "~/path/to/fluxo-rs cpu",
+    "on-click": "fluxo audio cycle sink && pkill -RTMIN+8 waybar"
-       "return-type": "json"
+},
-   }
+"custom/bluetooth": {
-   ```
+    "exec": "fluxo bt",
-
+    "return-type": "json",
-## Development
+    "interval": 5,
-
+    "signal": 9,
-### Architecture
+    "on-click": "fluxo bt menu && pkill -RTMIN+9 waybar",
-- `src/main.rs`: Entry point, CLI parsing, interactive GUI spawns (menus), and client-side formatting logic.
+    "on-click-right": "fluxo bt cycle_mode && pkill -RTMIN+9 waybar"
-- `src/daemon.rs`: UDS listener, configuration management, and polling orchestration.
+}
-- `src/ipc.rs`: Unix domain socket communication logic.
-- `src/utils.rs`: Generic GUI utilities (like the menu spawner).
-- `src/modules/`: Individual metric implementations.
-- `src/state.rs`: Shared thread-safe data structures.
-
-### Adding a Module
-1. Add the required config block to `src/config.rs`.
-2. Add the required state fields to `src/state.rs`.
-3. Implement the `WaybarModule` trait in a new file in `src/modules/`.
-4. Add polling logic to `src/modules/hardware.rs` or `src/daemon.rs`.
-5. Register the new subcommand in `src/main.rs` and the router in `src/daemon.rs`.
-
-### Configuration Reload
-The daemon can reload its configuration live:
-```bash
-fluxo-rs reload
 ```
 
-### Logging & Debugging
+## Debugging
-`fluxo-rs` uses the `tracing` ecosystem. If a module isn't behaving properly or your configuration isn't applying, start the daemon with debug logging enabled in the foreground:
+
+Start the daemon with `RUST_LOG=debug` to see detailed logs of library interactions and circuit breaker status:
 ```bash
 RUST_LOG=debug fluxo-rs daemon
 ```
-This will print verbose information regarding config parsing errors, subprocess failures, and IPC requests.
