This document defines the copyright and license header format required for source files in the hve-core repository. Following these guidelines ensures compliance with [OpenSSF Best Practices](https://www.bestpractices.dev/en/criteria/2) Gold badge criteria for `copyright_per_file` and `license_per_file`.

## Overview

All source files in this repository must include a copyright and license header. We use the [SPDX License Identifier](https://spdx.org/licenses/) standard to provide machine-readable license information.

## Header Format

### PowerShell Files

```text
# Copyright (c) Microsoft Corporation.
# SPDX-License-Identifier: MIT
```

Applies to: `.ps1` files

## Placement Rules

The header placement depends on any required directives in the file:

### With #Requires Statements

Place the header **after** any `#Requires` statements:

```powershell
#Requires -Version 7.0
#Requires -Modules @{ ModuleName="Pester"; ModuleVersion="5.0" }
# Copyright (c) Microsoft Corporation.
# SPDX-License-Identifier: MIT

# Script content starts here
```

### Without #Requires Statements

If no `#Requires` statements exist, place the header at the first line:

```powershell
# Copyright (c) Microsoft Corporation.
# SPDX-License-Identifier: MIT

param(
    [string]$Path
)
```
