+### Fixed
+- **Standalone installers** (`curl … | sh`, `irm … | iex`): the bundled launcher
+  failed with `exec: …/node: not found` because it didn't resolve the symlink the
+  installer puts on your PATH. Installing on a machine with **no Node** now works.
+- **npm**: `@colbymchenry/codegraph-linux-x64` is now published — the 0.9.0
+  release silently shipped 6 of 7 packages, so `npm i -g` on linux-x64 couldn't
+  find its bundle. The release pipeline now verifies every package reached the
+  registry (and is idempotent), so a release can't pass green-but-broken again.

 ## [0.9.0] - 2026-05-21
