Three issues prevented moonbit_wasm_component from building: 1. MoonBit toolchain was never registered - MODULE.bazel declared bazel_dep(name = "rules_moonbit") but never called use_extension or register_toolchains, causing Bazel to use the stub toolchain 2. MOON_HOME not set - moon build couldn't find moonbitlang/core standard library inside the Bazel sandbox 3. Missing sandbox inputs - moonbit_all_files wasn't included in action inputs, so the toolchain binaries (moonc, etc.) weren't available in the sandbox Also adds --encoding utf16 to wasm-tools component embed (required for MoonBit string encoding) and updates rules_moonbit to the commit with chmod + core bundle fixes. Verified: calculator component builds and exports correct WIT: export add: func(a: s32, b: s32) -> s32 export subtract: func(a: s32, b: s32) -> s32 export multiply: func(a: s32, b: s32) -> s32 export divide: func(a: s32, b: s32) -> s32 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
