## Changes

- Added `Codex Panel: Rewrite selection` for rewriting the current Markdown editor selection from an anchored popover, with rewrite-specific runtime settings, streaming progress, diffs, keyboard shortcuts, and stale-selection protection.
- Improved compatibility tracking for Obsidian and Codex app-server API baselines.
- Refined panel UI details for Obsidian window-aware rendering, diff lines, and composer spacing.
