Reads stdin, splits via CDC, deduplicates chunks against a sidecar block store at <archive>.blocks/, writes a chunk-hash manifest at <archive>. The reverse operation reads the manifest and reassembles the byte stream from the block store. Manifest format (magic UC2INGST) is a standalone container, not yet unified with the master-block archive layout. Tar boundaries are not preserved; the input is treated as an opaque byte stream. Follow-ups filed for both. Builds entirely on existing CDC + blockstore + merkle infrastructure. No new compression or hashing primitives. Tests cover small + 200 KB multichunk round-trip, idempotent dedup (repeat ingest of the same data reports zero new chunks and exact bytes_saved), empty stream, bad-magic rejection. Lint gate stays green. Closes fa0c7d4.
