Bug Report

Summary

After running bun install in the gbrain repo, the postinstall script fails with Permission denied on the gbrain binary.

Steps to Reproduce

1. Clone gbrain repo
2. Run bun install
3. Observe postinstall output

Error

/bin/bash: /Users/michael_claw/.bun/bin/gbrain: Permission denied
[gbrain] postinstall skipped. If installed via bun install -g github:...: run `gbrain doctor` and `gbrain apply-migrations --yes` manually.

Expected Behavior

Postinstall should either set the executable bit on the binary automatically, or not fail with a permission error.

Workaround

chmod +x ~/.bun/bin/gbrain

Environment

• OS: macOS Darwin 25.3.0 arm64
• Bun: 1.3.12
• gbrain: v0.19.0
