Vendored third-party licenses
=============================

MIT requires that the copyright notice and permission notice travel with every
copy of the software. The upstream texts below are reproduced verbatim from each
project at the commit its code was taken from. Each vendored source file carries
an SPDX tag and the upstream copyright in its header and points here.

One consolidated file rather than one per directory: `_gnn.py` is a single
vendored file with no directory of its own, and RelBench and RelGNN ship the
identical MIT text, so per-directory copies would duplicate and drift.
