Full technical files and history. Identical file bytes are stored once. Historical ZIP containers are expanded into <original-name>.zip.contents/ so duplicate technical files are not repeatedly downloaded. Original container names and SHA-256 are recorded in FILE-MANIFEST.json; the byte-identical ZIP container itself is not included. All included source/document bytes retain their per-file hashes.
Extract restore.py then run: python3 restore.py complete-technical-archive.zip NEW_DIRECTORY
