D375 - The payload SDK is a build tool, never a source

Status: decided Date: 2026-08-29

The open payload SDK is used only to compile payloads whose main and entry code are written here, which are then run and observed. Nothing is read from its runtime or headers, and nothing here is written while reading them.

Why: the SDK is GPL-3.0 and this project is MIT/Apache-2.0. A payload built with it is observed exactly as a commercial title is loaded and observed, and a probe whose code is ours separates the runtime's behaviour from any one payload's.

Rejected:

• Reading the SDK's runtime or headers: copies licensed source into the project's reasoning.
