This archive contains the preferred Emscripten 3.1.69 generator/runtime/header/system-library source installed by pinned SDK build8fe01288bc35668c13316324336ea00195dfb814. Installed revision c55ff404dbe1eb9f263c48b584d5ba627224763a differs from official tag3.1.69 commit40e6b046cf7d3d9d0789196a3e26689ccaec0948. Selected sources are checked against installed-revision Git blobs; installed package/version metadata and its official original blobs are separately preserved and identified in source-manifest.json. This is not described as a pristine tag tree. Compiler executables, SDK caches, test models, documentation/media, node_modules and binary artifacts are omitted. package.json/package-lock.json describe separately obtainable npm generator dependencies; no claim that this ZIP is a standalone compiler installation. Install pinned official emsdk toolchain as documented in the CAD source kit, then use this source tree with its matching LLVM/Binaryen tools. Optional third_party source and notices are preserved. Final embedded library selection requires link evidence; inclusion here is not a claim that every supplied library is incorporated.
