agentic-jujutsu@2.3.6 fails on macOS arm64: missing native package

Summary

Installing agentic-jujutsu@2.3.6 globally on macOS Apple Silicon succeeds, but running jj-agent fails because the package tries to require a missing native dependency:

Error: Cannot find module 'agentic-jujutsu-darwin-arm64'

Environment

• OS: macOS
• Architecture: arm64 / Apple Silicon
• Node: v24.15.0
• Package manager: npm via Volta
• Package: agentic-jujutsu@2.3.6

Reproduction

npm install -g agentic-jujutsu
exec zsh
jj-agent

Actual result

Error: Cannot find module 'agentic-jujutsu-darwin-arm64'
Require stack:
- .../agentic-jujutsu/index.js
- .../agentic-jujutsu/bin/cli.js

Expected result

jj-agent should start successfully on macOS arm64.

Investigation

The generated N-API loader attempts to load agentic-jujutsu-darwin-arm64 for process.platform === 'darwin' and process.arch === 'arm64'.

However, the published package metadata for agentic-jujutsu@2.3.6 only lists these optional dependencies:

{
  agentic-jujutsu-win32-x64-msvc: 2.3.6,
  agentic-jujutsu-darwin-x64: 2.3.6,
  agentic-jujutsu-linux-x64-gnu: 2.3.6,
  agentic-jujutsu-linux-x64-musl: 2.3.6,
  agentic-jujutsu-linux-arm64-musl: 2.3.6,
  agentic-jujutsu-linux-arm-gnueabihf: 2.3.6
}

There is no agentic-jujutsu-darwin-arm64 package published to npm, and agentic-jujutsu-darwin-universal also appears to be unpublished.

Additionally, the installed package included agentic-jujutsu.linux-x64-gnu.node inside the main package tarball, which appears incorrect for a macOS install.

Workaround

I cloned the upstream repository, built the package locally on macOS arm64 with:

npm install
npm run build

inside packages/agentic-jujutsu, then copied the generated agentic-jujutsu.darwin-arm64.node into the installed global package directory. After that, jj-agent version worked correctly.

Possible fix

Publish one of the following native packages for version 2.3.6:

• agentic-jujutsu-darwin-arm64
• or agentic-jujutsu-darwin-universal

and include it in optionalDependencies.

Alternatively, ensure the main npm tarball includes the correct macOS ARM .node file when publishing.

Start in packages/agentic-jujutsu and inspect the generated loader, package metadata, and npm publishing configuration alongside index.js and bin/cli.js. Reproduce the macOS arm64 install, verify the native package or .node file is published and listed as an optional dependency, and confirm that jj-agent starts successfully.
