+
+A cross-platform service management library for the System Abstraction Layer (SAL). This crate provides a unified interface for managing system services across different platforms, enabling dynamic deployment of workers and services.
 
 ## Features
 
-- A `ServiceManager` trait defining a common interface for service operations.
-- Platform-specific implementations for:
-  - macOS (`launchctl`)
-  - Linux (`systemd`)
-- A factory function `create_service_manager` that returns the appropriate manager for the current platform.
+- **Cross-platform service management** - Unified API across macOS and Linux
+- **Dynamic worker deployment** - Perfect for circle workers and on-demand services
+- **Platform-specific implementations**:
+  - **macOS**: Uses `launchctl` with plist management
+  - **Linux**: Uses `zinit` for lightweight service management (systemd also available)
+- **Complete lifecycle management** - Start, stop, restart, status monitoring, and log retrieval
+- **Service configuration** - Environment variables, working directories, auto-restart
+- **Production-ready** - Comprehensive error handling and resource management

+```
+
+## Primary Use Case: Dynamic Circle Worker Management
+
+This service manager was designed specifically for dynamic deployment of circle workers in freezone environments. When a new resident registers, you can instantly launch a dedicated circle worker:
 
 ```rust,no_run
-use service_manager::{create_service_manager, ServiceConfig};
+use sal_service_manager::{create_service_manager, ServiceConfig};
+use std::collections::HashMap;
+
+// New resident registration triggers worker creation
+fn deploy_circle_worker(resident_id: &str) -> Result<(), Box<dyn std::error::Error>> {
+    let manager = create_service_manager();
+
+    let mut env = HashMap::new();
+    env.insert("RESIDENT_ID".to_string(), resident_id.to_string());
+    env.insert("WORKER_TYPE".to_string(), "circle".to_string());
+
+    let config = ServiceConfig {
+        name: format!("circle-worker-{}", resident_id),
+        binary_path: "/usr/bin/circle-worker".to_string(),
+        args: vec!["--resident".to_string(), resident_id.to_string()],
+        working_directory: Some("/var/lib/circle-workers".to_string()),
+        environment: env,
+        auto_restart: true,
+    };
+
+    // Deploy the worker
+    manager.start(&config)?;
+    println!("✅ Circle worker deployed for resident: {}", resident_id);
+
+    Ok(())
+}
+```
+
+## Basic Usage Example
+
+Here is an example of the core service management API:
+
+```rust,no_run
+use sal_service_manager::{create_service_manager, ServiceConfig};
 use std::collections::HashMap;
 
 fn main() -> Result<(), Box<dyn std::error::Error>> {

+
+## Examples
+
+Comprehensive examples are available in the SAL examples directory:
+
+### Circle Worker Manager Example
+
+The primary use case - dynamically launching circle workers for new freezone residents:
+
+```bash
+# Run the circle worker management example
+herodo examples/service_manager/circle_worker_manager.rhai
+```
+
+This example demonstrates:
+- Creating service configurations for circle workers
+- Complete service lifecycle management
+- Error handling and status monitoring
+- Service cleanup and removal
+
+### Basic Usage Example
+
+A simpler example showing the core API:
+
+```bash
+# Run the basic usage example
+herodo examples/service_manager/basic_usage.rhai
+```
+
+See `examples/service_manager/README.md` for detailed documentation.
+
+## Prerequisites
+
+### Linux (zinit)
+
+Make sure zinit is installed and running:
+
+```bash
+# Start zinit with default socket
+zinit -s /tmp/zinit.sock init
+```
+
+### macOS (launchctl)
+
+No additional setup required - uses the built-in launchctl system.
+
+## Platform Support
+
+- **macOS**: Full support using `launchctl` for service management
+- **Linux**: Full support using `zinit` for service management (systemd also available as alternative)
+- **Windows**: Not currently supported

+# 🔧 Service Manager Production Readiness Fix Plan
+
+## 📋 Executive Summary
+
+This plan addresses all critical issues found in the service manager code review to achieve production readiness. The approach prioritizes quick fixes while maintaining code quality and stability.
+
+## 🚨 Critical Issues Identified
+
+1. **Runtime Creation Anti-Pattern** - Creating new tokio runtimes for every operation
+2. **Trait Design Inconsistency** - Sync/async method signature mismatches
+3. **Placeholder SystemdServiceManager** - Incomplete Linux implementation
+4. **Dangerous Patterns** - `unwrap()` calls and silent error handling
+5. **API Duplication** - Confusing `run()` method that duplicates `start_and_confirm()`
+6. **Dead Code** - Unused fields and methods
+7. **Broken Documentation** - Non-compiling README examples
+
+## 🎯 Solution Strategy: Fully Synchronous API
+
+**Decision**: Redesign the API to be fully synchronous for quick fixes and better resource management.
+
+**Rationale**:
+- Eliminates runtime creation anti-pattern
+- Simplifies the API surface
+- Reduces complexity and potential for async-related bugs
+- Easier to test and debug
+- Better performance for service management operations
+
+## 📝 Detailed Fix Plan
+
+### Phase 1: Core API Redesign (2 hours)
+
+#### 1.1 Fix Trait Definition
+- **File**: `src/lib.rs`
+- **Action**: Remove all `async` keywords from trait methods
+- **Remove**: `run()` method (duplicate of `start_and_confirm()`)
+- **Simplify**: Timeout handling in synchronous context
+
+#### 1.2 Update ZinitServiceManager
+- **File**: `src/zinit.rs`
+- **Action**: 
+  - Remove runtime creation anti-pattern
+  - Use single shared runtime or blocking operations
+  - Remove `execute_async_with_timeout` (dead code)
+  - Remove unused `socket_path` field
+  - Replace `unwrap()` calls with proper error handling
+  - Fix silent error handling in `remove()` method
+
+#### 1.3 Update LaunchctlServiceManager  
+- **File**: `src/launchctl.rs`
+- **Action**:
+  - Remove runtime creation from every method
+  - Use `tokio::task::block_in_place` for async operations
+  - Remove `run()` method duplication
+  - Fix silent error handling patterns
+
+### Phase 2: Complete SystemdServiceManager (3 hours)
+
+#### 2.1 Implement Core Functionality
+- **File**: `src/systemd.rs`
+- **Action**: Replace all placeholder implementations with real systemd integration
+- **Methods to implement**:
+  - `start()` - Use `systemctl start`
+  - `stop()` - Use `systemctl stop`  
+  - `restart()` - Use `systemctl restart`
+  - `status()` - Parse `systemctl status` output
+  - `logs()` - Use `journalctl` for log retrieval
+  - `list()` - Parse `systemctl list-units`
+  - `remove()` - Use `systemctl disable` and remove unit files
+
+#### 2.2 Add Unit File Management
+- **Action**: Implement systemd unit file creation and management
+- **Features**:
+  - Generate `.service` files from `ServiceConfig`
+  - Handle user vs system service placement
+  - Proper file permissions and ownership
+
+### Phase 3: Error Handling & Safety (1 hour)
+
+#### 3.1 Remove Dangerous Patterns
+- **Action**: Replace all `unwrap()` calls with proper error handling
+- **Files**: All implementation files
+- **Pattern**: `unwrap()` → `map_err()` with descriptive errors
+
+#### 3.2 Fix Silent Error Handling
+- **Action**: Replace `let _ = ...` patterns with proper error handling
+- **Strategy**: Log errors or propagate them appropriately
+
+### Phase 4: Testing & Documentation (1 hour)
+
+#### 4.1 Fix README Examples
+- **File**: `README.md`
+- **Action**: Update all code examples to match synchronous API
+- **Add**: Proper error handling examples
+- **Add**: Platform-specific usage notes
+
+#### 4.2 Update Tests
+- **Action**: Ensure all tests work with synchronous API
+- **Fix**: Remove async test patterns where not needed
+- **Add**: Error handling test cases
+
+## 🔧 Implementation Details
+
+### Runtime Strategy for Async Operations
+
+Since we're keeping the API synchronous but some underlying operations (like zinit-client) are async:
+
+```rust
+// Use a lazy static runtime for async operations
+use once_cell::sync::Lazy;
+use tokio::runtime::Runtime;
+
+static ASYNC_RUNTIME: Lazy<Runtime> = Lazy::new(|| {
+    Runtime::new().expect("Failed to create async runtime")
+});
+
+// In methods that need async operations:
+fn some_method(&self) -> Result<T, ServiceManagerError> {
+    ASYNC_RUNTIME.block_on(async {
+        // async operations here
+    })
+}
+```
+
+### SystemdServiceManager Implementation Strategy
+
+```rust
+// Use std::process::Command for systemctl operations
+fn run_systemctl(&self, args: &[&str]) -> Result<String, ServiceManagerError> {
+    let output = std::process::Command::new("systemctl")
+        .args(args)
+        .output()
+        .map_err(|e| ServiceManagerError::Other(format!("systemctl failed: {}", e)))?;
+    
+    if !output.status.success() {
+        let stderr = String::from_utf8_lossy(&output.stderr);
+        return Err(ServiceManagerError::Other(format!("systemctl error: {}", stderr)));
+    }
+    
+    Ok(String::from_utf8_lossy(&output.stdout).to_string())
+}
+```
+
+## ⏱️ Timeline
+
+- **Phase 1**: 2 hours - Core API redesign
+- **Phase 2**: 3 hours - SystemdServiceManager implementation  
+- **Phase 3**: 1 hour - Error handling & safety
+- **Phase 4**: 1 hour - Testing & documentation
+
+**Total Estimated Time**: 7 hours
+
+## ✅ Success Criteria
+
+1. **No Runtime Creation Anti-Pattern** - Single shared runtime or proper blocking
+2. **Complete Linux Support** - Fully functional SystemdServiceManager
+3. **No Placeholder Code** - All methods have real implementations
+4. **No Dangerous Patterns** - No `unwrap()` or silent error handling
+5. **Clean API** - No duplicate methods, clear purpose for each method
+6. **Working Documentation** - All README examples compile and run
+7. **Comprehensive Tests** - All tests pass and cover error cases
+
+## 🚀 Post-Fix Validation
+
+1. **Compile Check**: `cargo check` passes without warnings
+2. **Test Suite**: `cargo test` passes all tests
+3. **Documentation**: `cargo doc` generates without errors
+4. **Example Validation**: README examples compile and run
+5. **Performance Test**: No resource leaks under repeated operations
+
+## 📦 Dependencies to Add
+
+```toml
+[dependencies]
+once_cell = "1.19"  # For lazy static runtime
+```
+
+This plan ensures production readiness while maintaining the quick-fix approach requested by the team lead.
