Run: docker build -t lenbling-iris-source-build .
The Dockerfile pins emscripten/emsdk 3.1.64 by digest. TensorFlow pins its CMake dependencies by source revision.
Our bridge exports only model-open/invoke/output/close; model weights are not modified or redistributed in this source archive.
Build changes: disable optional XNNPACK/GPU/NNAPI/external delegates; single-thread link (remove pthread link options); consistent FlatBuffers locale definition; link the pinned cpuinfo project's original Emscripten init source omitted by its CMake platform test; 5MiB checked stack. All changes are visible in CMakeLists.txt and Dockerfile. No Eigen arithmetic source edits by LENBLING. TensorFlow's Eigen CMake configuration disables documentation/benchmark/Fortran test checks; the actual configured Eigen sources are provided separately.
