Exclusions route through a single shared walker in private/fs.ts, removing the duplicated hash implementations that disagreed with it on directory records and traversal order. Staging preserves symlinks instead of dereferencing them, applies exclusions relative to the copied tree, keeps scratch directories out of the assets outdir, and reuses staged results so bundling runs once per distinct asset. Custom hashes and type overrides are validated, salt now composes with extraHash, and cleanup of VOLUME_COPY resources covers the setup phase with each step attempted independently.
