- Create wasm/engine/ with main_wasm.go exporting loadState, step, runMatch, getReplay, getBots, getEnergy, getConfig, getState functions for browser sandbox use - Add engine/wasm.go with Match type providing WASM-friendly interface - Add wasm/engine/build.sh for GOOS=js GOARCH=wasm compilation - Update wasm/Makefile to include engine target - Successfully builds engine.wasm (~5.6 MB) with valid WASM magic number The engine WASM enables production-accurate match execution in the browser sandbox per plan §13.1. Build artifacts (.wasm files) are gitignored and generated on-demand. Closes: bf-1wew Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
