-          Read the tested desktop revision-store .one subset and single-cabinet

-          FSSHTTP sections, MSZIP and Quantum packages, multi-cabinet archives,
-          notebook TOC ordering, visual fidelity, attachments, and export are
-          not supported in this release.
+          Notebook trees, rich text, safe links, tables, PNG/JPEG images, ink,
+          attachments, and local JSON, text, Markdown, HTML, or static ZIP
+          exports are supported within documented safety and format limits.
+          Encountered unsupported object kinds remain visible as diagnostics.

+          Fragmented FSSHTTPB data, equations, audio/video, exact OneNote page
+          placement, and untested producer variants remain unsupported. Exports
+          preserve readable content but do not create OneNote files.

+          Nothing is uploaded or sent to telemetry, and the app stores no
+          notebook data unless you explicitly download a resource or create an
+          export. Closing or clearing releases application references and
+          terminates the worker; this is not a secure-erasure guarantee.
