Relocate bottle-owned text with the prefix authenticated by the VFS inventory instead of the repository's current default. This keeps immutable images readable after a prefix migration and preserves Node/browser parity in the shared filesystem path.
Make the Homebrew Cellar rule explicitly apply only to inventory entries marked for bottle relocation. Cover a mixed inventory so ordinary VFS sources can target valid guest paths outside the Cellar while malformed relocation entries fail closed.

Why
A published virtual filesystem (VFS) image records exact guest paths and
expected file sizes. An older public Homebrew image stores bottle files
under
/home/linuxbrew/.linuxbrew, while the current default prefix is/opt/kandelo/homebrew.The lazy-file runtime previously used the current default when replacing
Homebrew placeholders. That changed legacy bottle bytes and their lengths,
so the VFS integrity check correctly rejected the result and
/usr/bin/brewcould not start.The authenticated inventory for an immutable image must decide the prefix
used to relocate bottle files. This rule applies only to entries explicitly
marked
archive-homebrew-relocate. Ordinary VFS entries remain free to useany otherwise valid guest path, including paths outside Homebrew Cellar.
What changed
the same prefix.
marked
archive-homebrew-relocate.filesystem implementation.
This does not change the kernel or the Kandelo application binary interface
(ABI).
Validation
