## ⚙️ Runtime Lifecycle & MSRV Support Policy

![Rust MSRV & Release Schedule](docs/lts_schedule.svg)

### Policy Guarantee
XYO Financial adheres to a deterministic **Minimum Supported Rust Version (MSRV)** policy designed for mission-critical enterprise environments.

- **Guaranteed MSRV Baseline:** We guarantee support for our stated MSRV baseline (**Rust 1.75+** on **Rust Edition 2021**).
- **3-Month Proactive Window:** We will never raise the MSRV without at least **3 months advance notice** in release notes and documentation before cutting a release requiring a newer compiler baseline.

| Compiler Track | Edition | Status | SDK Support Level |
| :--- | :--- | :--- | :--- |
| **Rust 1.85+** | 2021 / 2024 | :white_check_mark: Active Stable | **Current Recommended Target** |
| **Rust 1.80 – 1.84** | 2021 | :white_check_mark: Active Stable | Fully Supported |
| **Rust 1.75 – 1.79** | 2021 | :lock: Baseline Floor | **Guaranteed Minimum MSRV Floor** |
| **Rust < 1.75** | 2018 / 2021 | :x: Deprecated | **Unsupported / Compiler Incompatible** |
