The Docker build used emscripten/emsdk:4.0.2-arm64 as base image but env.sh couldn't find emsdk there, installing a second copy. The build then applied wasm-opt/finalize stubs to the wrong emsdk (hardcoded /emsdk/), so the real wasm-emscripten-finalize ran in Docker and got OOM-killed. - Use ubuntu:22.04 base with emsdk installed from source at /emsdk/ - Make stub paths dynamic via $EMSDK instead of hardcoded /emsdk/ - Skip local emsdk install in env.sh when $EMSDK is already active Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
