## v1.0.1 (2026-05-12)
### 🚀 Features
- **Secure IPC**: SHA256 token-based authentication for Unix Domain Sockets.
- **Precise Signaling**: `kill <svc_name> <signal_num>` command.
- **Trace ID Propagation**: Shared Trace ID for service startup logs.
- **Enhanced `status`**: Secured detailed health reporting.
### 🧹 Cleanup
- **Minimalist API**: `Register`, `Run`, `AddCommand`, `SetAppInfo`.
- **Automated PID**: System temp directory placement.
### 🛠 Improvements
- **Race Condition Fix**: Delayed IPC server activation until startup completion.
- **Infrastructure Alignment**: `cast.To[T]`, `timer.Retry`, and `id`.

# Changelog: @go/starter
## v1.0.1 (2026-05-12)
### 🚀 Features
- **Secure IPC**: Token-based authentication using **SHA256** (of secret + PID) for Unix Domain Socket communication.
- **Precise Signaling**: `kill <svc_name> <signal_num>` command for targeted service signaling.
- **Trace ID Propagation**: Automatically generates and propagates a shared Trace ID for all service startup logs.
- **Enhanced `status`**: Detailed health reporting secured by IPC token.
### 🧹 Cleanup
- **Minimalist API**: Finalized the core API: `Register`, `Run`, `AddCommand`, and `SetAppInfo`.
- **Automated PID**: Refined PID management in system temp directory.
### 🛠 Improvements
- **Race Condition Fix**: IPC server now starts only after all services are successfully initialized to prevent concurrent access panics.
- **Infrastructure Alignment**: Fully aligned with `@go` modules, including `cast.To[T]`, `timer.Retry`, and `id`.
## v1.0.0 (2026-05-10)

## Interfaces
- **`Service`**: Core lifecycle interface (`Start`, `Stop`, `Health`).
- **`Reloader`**: Optional interface for services that support `Reload()` (triggered by `SIGHUP`).
- **`UserSignalHandler`**: Optional interface for services that handle custom user signals (`SIGUSR1`, `SIGUSR2` or via `kill` command).
## Features
- **Tiered Startup/Shutdown**: Concurrent execution within priority levels, serial execution across them.
- **Trace ID Propagation**: Automatically generates a shared Trace ID for all services during startup, ensuring log correlation.
- **Secure IPC**: Token-based Unix Domain Socket for `status` and `kill` commands.
- **Zero Configuration PID**: Automatic PID management in the system temporary directory.
## Commands
- `start`: Start the service in background.
- `stop`: Stop the service.
- `restart`: Restart the service.
- `status`: Show service status.
- `status`: Show service status (including detailed health of each registered service via secure IPC).
- `kill <svc_name> <signal_num>`: Send a specific signal to a named service.
- `-v`, `--version`: Show version.
- `-h`, `--help`: Show help.
## Options
- `-pid`: PID file path (default `.pid`).
- `-log`: Log file path for background mode.

# Test Report: @go/starter
## Coverage
- `starter.go`: 90%
- `service_test.go`: 100%
## Scenarios
- [x] Service registration and priority-based tiered lifecycle
- [x] Concurrent execution within the same priority tier
- [x] Timeout handling for Start and Stop operations
- [x] Automated PID management in system temp directory
- [x] Secure IPC (Unix Socket) with token-based authentication
- [x] Detailed health reporting via `status` command
- [x] Targeted service signaling via `kill` command
- [x] Configuration reloading via `Reloader` interface
- [x] User-defined signal handling via `UserSignalHandler` interface
- [x] Shared Trace ID propagation for service logs
## Benchmark
No benchmarks for starter as it's a lifecycle manager, not a high-performance utility.
