Linux LLVM helper packages ship scriptc-llvm-codegen without the executable bit #430

Summary

The Linux LLVM helper packages publish bin/scriptc-llvm-codegen with mode 0644, so every native build on Linux fails right after npm install scriptc:

error SC3003: LLVM native helper package @scriptc/llvm-linux-x64-gnu is incomplete: .../node_modules/@scriptc/llvm-linux-x64-gnu/bin/scriptc-llvm-codegen is not readable and executable; reinstall scriptc

Reinstalling doesn't help. chmod +x on the helper does.

Evidence

$ for p in llvm-linux-x64-gnu llvm-linux-x64-musl llvm-linux-arm64-gnu llvm-darwin-arm64; do npm pack -s @scriptc/$p@0.1.4 >/dev/null; tar tvzf scriptc-$p-0.1.4.tgz | grep bin/; done
-rw-r--r-- 0/0 46432280 1985-10-26 08:15 package/bin/scriptc-llvm-codegen   # linux-x64-gnu
-rw-r--r-- ...                                                               # linux-x64-musl
-rw-r--r-- ...                                                               # linux-arm64-gnu
-rwxr-xr-x ...                                                               # darwin-arm64

@scriptc/llvm-linux-x64-gnu 0.1.2 and 0.1.3 have the same 0644 mode.

Cause

release.yml restores 755 on every bin/scriptc-llvm-codegen before packing, but pnpm pack then normalises file modes: it keeps the executable bit only for files named in the manifest's bin field. packages/llvm-darwin-arm64/package.json declares

"bin": { "scriptc-llvm-codegen": "bin/scriptc-llvm-codegen" }

and the Linux helper manifests don't ("bin" appears only in files). I reproduced this with pnpm 11.1.3 by packing both package directories with a 755 stand-in binary: the darwin tarball kept rwxr-xr-x, and the linux-x64-gnu tarball got rw-r--r--.

scripts/verify-llvm-package.mjs already checks the bin entry and X_OK, but the release job runs it only on the darwin-arm64 tarball, so it can't catch this.

Suggested fix

• Add the same bin entry to the Linux helper manifests (and win32 for consistency).
• Run verify-llvm-package.mjs on every helper tarball, not just darwin-arm64.

Environment

scriptc 0.1.4, Ubuntu 26.04 x86_64, Node 24.21.0, npm 11.19.0.
