Full changelog

Mog SDK v0.9.3 promotes a broad spreadsheet stabilization release with the public Codex plugin integration, stronger editing/navigation behavior, and improved chart/XLSX fidelity.

Primary PR: #58 - Release v0.9.3 to main

Codex Plugin

Public Codex plugin path — adds the public plugin integration, MCP server, browser host source, Mog spreadsheet skill, and marketplace metadata while keeping the large generated browser bundle out of normal git tracking.

Editing And Navigation

Paste and formula editing — hardens paste target routing, tiling, overwrite handling, paste-special labels, internal HTML paste classification, formula point-mode scrolling, cross-sheet cancel return, and Goal Seek range picking.
Selection and dialogs — improves note/comment popovers, Ctrl+G routing, exact Find priority, shift-click selection, merged-cell selection, and active-cell/range-selection follow behavior.

Tables And Outlines

Sort and filter behavior — routes keyboard sort through active AutoFilters, preserves explicit headerless and visible-row sort intent, scopes range-backed sort dispatch, and filters stale table-backed compact reads.
Grouping and outline state — covers table filter undo/redo header replay and repairs imported outline detail toggles and group targets.

Compute And Kernel

Structural edit safety — preflights structural edits before mutable grid borrows, hydrates and invalidates imported/deferred formulas across structural deletes, and remaps hidden caches after edits.
State replay consistency — syncs mirror positions after row-order sort, refreshes viewports after history replay, and materializes API-created data table bodies.

Charts, XLSX, And Devtools

Chart and XLSX fidelity — preserves imported chart frame extents and axis defaults, hardens authored chart exports, respects chart wizard source selections and title inference, and fixes collapsed-outline chart sources.
Devtools readbacks — expands readbacks for cell size, charts, diagrams, merged cells, and text clipping.

SDK And Public Surfaces

API guidance and metadata — refreshes SDK agent guidance, API compatibility metadata, Python SDK surface dispositions/stubs, release-aligned public package metadata, and sanitized public test wording.
