+- Commit: `8ade43ce5` (zsh: use OSC 133 P for prompt redraws)
+- Files:
+  - `src/shell-integration/zsh/ghostty-integration`
+- Summary:
+  - Emits one `OSC 133;A` fresh-prompt mark for real prompt transitions.
+  - Uses `OSC 133;P` markers for prompt redraws so async zsh themes do not look like extra prompt lines.
+
+The fork branch HEAD is now the section 5 zsh redraw commit.
