# Task 7 minimal offline preservation

User-approved shared backup for continued work by root, Claude and Grok. This independent backup branch does not update the release candidate, main, dev or tags.

Source snapshot: `0f8fdbc30ea640c764b38ee598d8f4d135c81c85`, branch `release-prep/2d-jet-multilevel-20261020`, tree `e0ab4a6b974d188e8bf1a1cedd0d2705ef27cefe`. The snapshot contains 247 selected source/test/documentation files; it is not a full Git history.

`horsea-required.tar.gz` is the original unchanged 729332-byte pack. Its 309 payload files and embedded manifest were verified after Horsea-to-Mac transfer. It contains the saved SRT input NPZ/PTX, matching-cache/rebuilt SASS text, exact RNE scratch scripts/results/provenance, and recent gate/integration summaries. No credentials, raw caches, cubins, training outputs or unrelated data are included. Git authentication is not part of this backup.

The embedded manifest retains its original local-preservation wording. The user subsequently explicitly approved sharing this exact pack through this Gitea backup branch; the original archive and manifest bytes are preserved.

After retrieval, verify the files against `SHA256SUMS` before unpacking. `MANIFEST.json` lists each payload origin, byte size and SHA256. The archive contains regular files only and no absolute or parent-traversal paths.

Evidence limitations remain: blocked historical SASS was rebuilt, matching uniform cache usage was not bound to the old run receipt, and current-candidate GPU reproduction plus measured GPU reciprocal were not executed. This backup does not establish release acceptance or an SRT fix.
