SheetMog

Mog SDK v0.10.3 focuses on worksheet annotations, spreadsheet UI correctness, and expanded XLSX package fidelity.

Primary PR: #319 — Release v0.10.3

Annotations

• Worksheet annotations — adds end-to-end annotation support across compute storage, kernel APIs, contracts, generated types, SDK metadata, and the spreadsheet UI.
• Annotation editing UI — adds the cell annotation panel and formula-bar annotation popover, including handling for long annotations.

Spreadsheet UI

• Filter correctness — fixes validation-range filters, deterministic worksheet filter targeting, autofilters next to table filters, and clear-filter readiness/performance.
• Interaction fixes — improves collapsed ribbon routing, Format Cells launchers, ribbon command reachability, chart source ranges over collapsed columns, and hidden-column horizontal scrolling.

XLSX Fidelity

• Opaque package preservation — expands roundtrip fidelity for ActiveX, OLE, form controls, drawing media, header/footer images, rich data, printer settings, note VML media, custom sidecars, and related package closures.

SDK And Runtime

• Worksheet API structure — splits the large worksheet implementation into focused modules while preserving the public API surface.
• Runtime layout metrics — threads runtime layout metrics through compute/kernel bridge paths and refreshes generated bridge/API artifacts for TypeScript, Python, N-API, WASM, contracts, SDK, and CLI skill references.
