THIRD-PARTY SOFTWARE
====================

The analysis engine (`br-sidecar`) is a separate native executable, shipped
inside the mod jar and unpacked on first use. It statically links the two
components below, so their terms travel with every copy of that binary.

FrameCore — MIT License
-----------------------
The finite element solver. Consumed as an external source dependency that this
repository does not carry; the three patches this project applies to it are in
`sidecar/patches/`. Copyright and permission notice: `third_party/FrameCore-MIT.txt`.

Eigen — Mozilla Public License 2.0
----------------------------------
Linear algebra, used by FrameCore. `br-sidecar` is built with `EIGEN_MPL2_ONLY`,
so only MPL-2.0 parts of Eigen are compiled in — no LGPL-licensed components.
Full text: `third_party/Eigen-MPL2.txt`.

MPL-2.0 section 3.2 requires that recipients of the binary be told how to obtain
the source of the covered code. Eigen's source is at
<https://gitlab.com/libeigen/eigen>, and the exact version this build uses is
whatever the building machine's `libeigen3-dev` provides — recorded, with the
host and every source hash, in `evidence/verification.json`. `br-sidecar` itself
is built from `sidecar/` in this repository and its build is byte-reproducible
on a matching toolchain.


NOT INCLUDED
============

Minecraft and Minecraft Forge are neither included nor redistributed here. This
is an unofficial mod: it is not approved by or associated with Mojang or
