@ruvector/gnn-darwin-arm64 missing prebuilt binary (darwin-arm64)

[ryaker]

Bug Report

Package: @ruvector/gnn v0.1.23
Platform: macOS darwin-arm64 (Apple Silicon)

Problem

The @ruvector/gnn-darwin-arm64 optional dependency is published to npm but contains only a package.json — the prebuilt native binary ruvector-gnn.darwin-arm64.node is missing.

Steps to Reproduce

```bash
npm install @ruvector/gnn
node -e "require('@ruvector/gnn')"
```

Error

```
Error: Cannot find module '/path/to/node_modules/@ruvector/gnn-darwin-arm64/ruvector-gnn.darwin-arm64.node'.
Please verify that the package.json has a valid "main" entry
```

Verification

```bash
ls node_modules/@ruvector/gnn-darwin-arm64/

Output: package.json

Expected: package.json ruvector-gnn.darwin-arm64.node

```

The package.json declares "main": "ruvector-gnn.darwin-arm64.node" and "files": ["ruvector-gnn.darwin-arm64.node"] but the .node file was not included in the published package.

Impact

• npx ruvector hooks pretrain Phase 8 always skips GNN: ⏭️ @ruvector/gnn not installed
• Graph relationship analysis (Phase 9) is also degraded

Expected

The darwin-arm64 prebuilt binary should be included in the npm publish, similar to how @ruvector/attention-darwin-arm64 correctly ships its .node file.

Environment

• Node.js: $(node --version)
• npm: $(npm --version)
• OS: macOS $(sw_vers -productVersion) (Apple Silicon M4)
• ruvector: $(npx ruvector --version 2>/dev/null)

Fix Merged — PR #210

Root Cause

The build-gnn.yml CI workflow used npx napi build without scoping to the ruvector-gnn-node crate, causing it to compile all workspace cdylib targets. This worked on Linux (x64-gnu) but failed on macOS and Windows runners because unrelated crates (e.g., ruvector-attention-node) had platform-specific build issues. As a result, the darwin-arm64 platform package was published with only package.json (677 bytes) and no .node binary.

Fix Applied

1. Scoped the napi build: Added --cargo-flags="-p ruvector-gnn-node" to only compile the GNN node crate
2. Installed @napi-rs/cli globally: Matches the working build-attention.yml pattern
3. Added binary verification: Publish step now checks binary exists before npm publish
4. Added musl targets: linux-x64-musl and linux-arm64-musl now in build matrix
5. Bumped to v0.1.24: Published @ruvector/gnn@0.1.24 and @ruvector/gnn-linux-x64-gnu@0.1.24 with correct binaries

Published

• @ruvector/gnn@0.1.24 — main package with updated optionalDependencies
• @ruvector/gnn-linux-x64-gnu@0.1.24 — 842KB binary included (verified)

Next Step

The CI workflow (run #22397161705) is building all platform binaries now. Once complete, a manual workflow dispatch with publish: true or a version tag push will publish the remaining platform packages:

• @ruvector/gnn-darwin-arm64 (the one reported in this issue)
• @ruvector/gnn-darwin-x64
• @ruvector/gnn-win32-x64-msvc
• @ruvector/gnn-linux-arm64-gnu
• @ruvector/gnn-linux-arm64-musl
• @ruvector/gnn-linux-x64-musl

Once the darwin-arm64 binary is published, npx ruvector hooks pretrain Phase 8 (GNN) will work on Apple Silicon.

Resolved - All platform binaries published

All 7 platform packages are now published to npm with their native binaries:

Package	Version	Files	Size
@ruvector/gnn-darwin-arm64	0.1.24	2	721 KB
@ruvector/gnn-darwin-x64	0.1.24	2	765 KB
@ruvector/gnn-win32-x64-msvc	0.1.24	2	786 KB
@ruvector/gnn-linux-x64-gnu	0.1.24	2	843 KB
@ruvector/gnn-linux-x64-musl	0.1.24	2	✓
@ruvector/gnn-linux-arm64-gnu	0.1.24	2	✓
@ruvector/gnn-linux-arm64-musl	0.1.24	2	✓

The darwin-arm64 package previously had only 1 file (677 bytes, just package.json). It now correctly includes the native .node binary.

Verification:

npm install @ruvector/gnn@0.1.24
node -e "const gnn = require('@ruvector/gnn'); console.log(gnn.init())"
# Should print: "Ruvector GNN Node.js bindings initialized"
