Rebuilding the engine

# Download every patch above into ./patches, then:
git clone https://github.com/beyond-all-reason/RecoilEngine.git RecoilWasm
cd RecoilWasm && git checkout e9d199329538cd9078a621c5e0f9ada416e1229f
git submodule update --init --recursive
# recoil-wasm.patch first; the other recoil-*.patch files are incremental on top of it.
# Apply in name order, repeating passes until none applies (already applied ones fail --check).

# Build with emsdk 6.0.9 (commit c59d6e841da55c2c21af32004c4c173cbd1c0f10), as scripts/engine-build.mjs
# and scripts/headless-build.mjs do in the WebBAR repository.

native-sync-trace.patch applies only to the native reference build used for sync verification. The WebBAR repository's scripts/ci/patch-provenance.mjs checks that these patches reproduce the engine tree exactly. For a copy of the full WebBAR build scripts, contact the site operator.
