+# Native protected attachment boundaries
+
+Synthetic OneNote 2010 section with an exact known password in
+[manifest.json](manifest.json), including a supplementary Unicode character and a
+combining mark. All pages and attachments were generated by native OneNote.
+[The generator](../../tools/native/external-assets.ps1) accepts the recorded lengths.
+
+The notebook is the native protected image. `read/` contains an independent
+fresh-clone, empty-cache unlock oracle. Its `environment.json` says `cold: false`
+because the read reused the cache that the preceding isolated cold-open and
+unlock step established; that step is recorded separately in the manifest.
+
+Attachment plaintext is reproducible: repeat the 1024-byte block whose byte at
+index `i` is `i % 251`, truncated to the recorded length. Native exported hashes
+are in `read/payloads.json`; no second copy of those generated bytes is retained.
+The zero-length attachment has a zero-length stored payload even when protected.
+
+The initially rejected UI attempt is excluded. Source notebooks and personal
+profiles were never edited. This fixture establishes native 2010 behavior for
+these inputs; its password and contents are deliberately public.
