# docs/downstream — agent guide

## Overview

Registry of external repositories that apply GNN. [README.md](README.md) is the
index; one Markdown file per repository carries the full evidence. Every claim
must be verified against the repository it describes on that repository's origin
default branch.

## Verification rules

- Verify from the repository itself on its origin default branch; never copy a
  claim from internal notes or from another row.
- Cite the pin file and the workflow job, test file or command that carries the
  evidence. If evidence is absent, write "not verified" or "no GNN-specific CI
  job" instead of implying more.
- Re-verify a row when its repository changes its pin file or GNN specification.
