SheetMog

Mog SDK v0.9.6 is a broad spreadsheet fidelity and workflow release focused on chart roundtrips, pivot correctness, and spreadsheet UI polish.

Primary PR: #308 - Release v0.9.6: chart fidelity, pivots, and spreadsheet polish

Highlights

XLSX chart, drawing, and roundtrip fidelity

• Preserves substantially more imported chart state through parse, SDK/domain conversion, reconstruction, and export.
• Improves fidelity for source ranges, graphic frame transforms, ChartEx modeled state, color styles, trendline aliases, rich text titles, data labels, axis flags/crossings, tick labels, gridlines, legends, chart data tables, and user shape drawing paths.
• Tightens series handling across scatter, bubble, of-pie, radar, line, surface, bar3D, secondary axes, marker/point formatting, leader/connector lines, pie explosions, 3D bubble flags, dash styles, shadows, smoothing defaults, and inherited label materialization.
• Preserves sparkline source sheets and theme colors through roundtrip paths.

Pivot table correctness and UI workflows

• Refactors pivot bridge responsibilities into focused mapping, placement, and source helpers.
• Serializes pivot field mutations and centralizes mutation receipts to keep UI, kernel, and compute state aligned.
• Improves field-list checkboxes, drag/drop controls, field placement activation, pointer targeting, and autoscroll.
• Fixes pivot context menu resolution and value targeting across overlays and rendered pivot cells.
• Improves pivot materialization, shared item identity, outline row labels, page field selections, export filter visibility, copied-sheet retargeting, and output-cell write protection.

Spreadsheet app behavior and rendering polish

• Fixes formula bar drag resizing and inline editor vertical alignment.
• Fixes row autofit through the UI path and current-region detection beyond the viewport window.
• Improves filter menu subcommands, color-filter menus, sort-by-color menus, and filter header button alignment.
• Preserves View Show group label layout and gesture zoom per sheet.
• Fixes spreadsheet font-size unit rendering plus accounting/currency rendering geometry.
• Routes chart selection through object commands and expands chart object command coverage.

Public API, contracts, and generated surfaces

• Fixes public range API sheet identity handling and adds public range type/API exports.
• Updates SDK API spec and guidance artifacts plus contract snapshots for chart, range, pivot, sparkline, and mutation receipt changes.
• Expands chart public API converters, chart type converters, size units, source diagnostics, and compatibility handling.
• Tightens non-eval gate type boundaries and compute bridge mutation admission behavior.

Verification

• Production publish workflow completed successfully for sdk-v0.9.6.
• npm post-publish verification completed successfully in CI.
• Python/PyPI publish was intentionally skipped for this SDK release.
