📝 WalkthroughWalkthroughThe CI workflows use checksum-verified musl cross-toolchains for x86_64 and aarch64 builds. They configure target-specific tools and Rust linkers, inspect addon ELF metadata, and test addon loading in Alpine with optional QEMU support. ChangesMusl addon pipeline
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The release workflow can still publish an x86_64 addon built against glibc because the ELF checks only report dependencies without rejecting GLIBC symbols or glibc libraries; additionally, relevant pull requests do not automatically run the regression workflow. These gaps should be fixed before merging. Sequence Diagram(s)sequenceDiagram

In @.github/workflows/build2-nodejs-sdk.reusable.yaml:
- Around line 234-236: The native dependency check in the workflow must reject
all glibc-linked musl artifacts, including NEEDED entries for libpthread.so.0,
libm.so.6, libdl.so.2, librt.so.1, libresolv.so.2, and libutil.so.1, not only
libc.so.6 and the dynamic loader. Extend the denylist or validate each musl
target in a matching Alpine environment, and update the release-pipeline
contract tests covering the ABI check to verify the expanded rule.

Obsolete review of the temporary one-off validation workflow, which was intentionally removed from the final diff after its successful run. All associated comments were answered and resolved; CodeRabbit reports no files remain to re-review on the current SHA.

matrix._.beforehook.GLIBC_*symbols or glibc runtime dependencies before upload.Root cause
The x86_64 musl matrix entry configured
CC_x86_64_unknown_linux_musl=musl-gccfor C build scripts but did not configure Cargo's final linker. Cargo therefore linkedbaml_node.linux-x64-musl.nodewith Ubuntu's glibc hostcc. Ubuntu's lightweightmusl-gccwrapper also lacks the musl-compatible dynamiclibgcc_s.so.1required by this cdylib, so both musl targets now use complete cross toolchains and sysroots.Validation
