Folderbase Core 0.7.2

Folderbase Core 0.7.2 adds the public producer boundary for exact root reconstruction packages. A Platform or App adapter can supply one exact Folderbase Version, immutable Object Version-to-Chunk Manifest associations, retained-Tombstone fidelity, and canonical manifests without reimplementing Core's private package JSON or reference-closure rules.

Folderbase remains Beta. This patch does not expand Compatibility Contract v1, change Folderbase Version identity, deploy Folderbase Cloud, synchronize an existing non-empty root, or grant any sharing authority.

Install

npx --yes @folderbase/cli@0.7.2 --version
cargo install folderbase-cli --version 0.7.2 --locked
brew install chalkagents/tap/folderbase

Native macOS and Linux executables plus SHA256SUMS are on the immutable GitHub release.

Core-owned package closure

The Rust API exposes two bounded operations:

• derive_root_reconstruction_package_closure validates the exact Version and derives Object IDs, semantic roles, and retained-Tombstone fidelity without reading manifests; and
• build_root_reconstruction_package consumes canonical manifests, writes a deterministic bounded package index, and validates the result through the same public decoder used by reconstruction consumers.

Live regular files and retained Tombstones become external object references. Live symlinks remain exact Version data and are derived during reconstruction, so adapters do not invent roleless symlink associations.

The builder handles Markdown, CSV, PDFs, office documents, SQLite snapshots, videos, archives, Git working trees, executables, unknown binaries, empty files, symlinks, exclusions, and Tombstones as ordinary opaque Folderbase data.

Compatibility

Core 0.7.2 retains the stable folderbase.root-reconstruction@0.1.0 capability, Compatibility Contract v1, CLI JSON v1, native root-manifest profile 0.5.0, Folderbase Version profiles 0.4 and 0.5, stable IDs, explicit upgrade behavior, and exit meanings 0, 1, and 2.
