The six source files are extracted from committed Git blobs; they are evidence, not an additional production tree. Notes retain their original bytes, including historical local paths and source-scoped statements. The manifest lists portable archive-relative paths plus original source provenance. It does not claim tests, native acceptance, import, or publication succeeded. Subsequent gates remain separate source-identified records owned by the integration owner.

From repository root, run the helper with verify to compare payload bytes, manifest metadata, source blobs and regenerated patch. After owner-controlled staging, run verify-index to additionally compare every payload and manifest with Git index blobs. Neither mode stages or rewrites files. If Git attributes normalize archived bytes, index verification fails; the owner must resolve that explicitly. No patch is applied by this helper.
