# ADR-0004: GPL-3.0-or-later

- Status: accepted
- Date: 2026-07-16

## Decision

Project-owned code is licensed GPL-3.0-or-later.

## Rationale

The planned RetroArch adapter targets a GPLv3 project and the PS5 Payload SDK is
generally GPLv3-or-later. A common GPL-compatible project license keeps the
combined distribution boundary understandable. Third-party code is not
vendored and retains its own notices.
