asset handoff / manifest / local

Create a revised asset handoff from a manifest.

Compare a previous and current manifest locally, then create changed-only manifest, explanation, and receiver-checklist files. Nothing is uploaded, transferred as a ZIP, or stored externally.

Compare current and previous manifests

Fixed format: path,kind,checksum,revision. Use a 64-character lowercase SHA-256-style checksum and a unique path in each manifest.

Start with the synthetic example. A wrong header, duplicate path, invalid checksum, or empty current manifest creates no outputs.
