+
+- Add a standalone React/Vite reader integrated with Toolbox SDK 0.1.1,
+  including `AppShell`, the Toolbox manifest, nested-path-safe assets, and the
+  Portal release contract.
+- Add a worker-hosted native TypeScript parser for a desktop OneNote
+  revision-store subset: bounded file-node and object-space traversal,
+  property sets, page metadata, titles, timestamps, levels, and plain text.
+- Add in-memory CAB enumeration and extraction for uncompressed and LZX
+  folders, including checksums, strict paths, explicit resource limits, and
+  cooperative cancellation between data blocks.
+- Open contained `.one` sections independently and expose package entries,
+  section/page navigation, partial failures, and structured diagnostics.
+- Verify a Joplin `.one` golden with three pages and a Joplin LZX `0x1203`
+  `.onepkg` golden with seven entries, five sections, and seven pages. Also
+  verify rust-cab uncompressed and LZX `0x1303` fixtures.
+- Add deterministic static release packaging, SHA-256 sidecars, pinned-source
+  provenance, fixture licensing, and security/support documentation.
+
+Known unsupported areas are FSSHTTP-packaged `.one`, MSZIP and Quantum CAB
+extraction, multi-cabinet archives, `.onetoc2` hierarchy/order interpretation,
+visual content, attachments, layout/format fidelity, links, and exports.
