Internal ChangesSection of the release
What
The unix-socket peer credential lookup dropped its separate macOS and Linux implementations in favour of a single runtime call.
Details
- Both platforms now call
Bun.ant.getPeerUid(t) - Still returns null on Windows
- Other failures log "[daemon] peer uid lookup failed:" with the error
Evidence
Bun.ant.getPeerUid
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
