# Repartir v1.0.0 - Release Notes

**Repartir** is a pure Rust library for distributed execution across CPUs, GPUs, and remote machines. Built on the **Iron Lotus Framework** (Toyota Way principles for systems programming).

## 🎯 Release Highlights

- **Test Coverage**: 88.58% (up from 64.97%)
- **Total Tests**: 105+ tests (92 unit + 9 integration + 4 property)
- **Quality Grade**: A (TDG score: 94.6/100)
- **pmat Compliance**: Pre-commit hooks with TDG enforcement

## ✨ Key Features

- **100% Rust**: Zero C/C++ dependencies (except aws-lc-rs in rustls)
- **CPU Executor**: Work-stealing scheduler based on Blumofe & Leiserson (1999)
- **GPU Executor**: wgpu-based GPU detection and initialization (v1.1+)
- **Remote Execution**: TCP-based task distribution with bincode protocol
- **TLS Encryption**: rustls with certificate-based authentication (TLS 1.3)
- **Messaging Patterns**: PUB/SUB and PUSH/PULL for distributed coordination
- **Priority Scheduling**: High, Normal, and Low priority queues
- **Fault Tolerance**: Task retry, timeout handling, graceful failure

- Overall: 64.97% → 88.58% (+23.61pp)

## 🏗️ Iron Lotus Framework

Built with Toyota Production System principles:

- **Jidoka (自働化)**: Built-in quality with automated gates
- **Kaizen (改善)**: Continuous improvement with TDG tracking
- **Genchi Genbutsu (現地現物)**: Transparent, auditable pure Rust
- **Muda (無駄)**: Zero waste, no YAGNI features

## 🚀 Quick Start

```toml
[dependencies]
repartir = "1.0"
tokio = { version = "1.35", features = ["rt-multi-thread", "macros"] }
```

```rust
use repartir::{Pool, task::{Task, Backend}};

#[tokio::main]
async fn main() -> repartir::error::Result<()> {
    let pool = Pool::builder().cpu_workers(4).build()?;

    let task = Task::builder()
        .binary("/bin/echo")
        .arg("Hello from Repartir!")
        .backend(Backend::Cpu)
        .build()?;

    let result = pool.submit(task).await?;
    println!("Output: {}", result.stdout_str()?.trim());

    pool.shutdown().await;
    Ok(())
}
```
