Edit Mode leaves task markers as raw text, and Enter on an empty task can keep users inside the list. Starting another item after exiting can also collapse the blank separator and pull the new item upward.

Render task markers as clickable checkboxes while typing. Enter continues with an unchecked task; Enter on an empty item exits with a blank separator. Preserve authored blank-line height when a new list marker appears. Checked tasks use Read Mode's muted strikethrough, checkbox sizing, indentation, and label spacing.

Based on #456 so this diff contains only the checkbox follow-up. Merge #456 first, then retarget this PR to main.

Validation:

  • Swift/WebKit regressions cover typed tasks, continuation and exit, nested/quoted tasks, literal fenced code, stable caret geometry after double Enter, completion styling, and Read/Edit checkbox geometry.
  • Debug app build passed.
  • Verified typing, toggling, saving, and checkbox layout in the rebuilt macOS app.
  • The editor smoke suite retains the previously confirmed baseline failure for clicking image source; the checkbox work does not change that path.

Summary by CodeRabbit

  • New Features
    • Task markers become interactive checkboxes after the closing bracket is typed. Toggling a checkbox updates the task, and completed tasks display a checkmark and strikethrough text.
    • Pressing Enter in a task continues the list; pressing Enter on an empty task exits it. Task lists retain their indentation and context.
  • Bug Fixes
    • Blank lines between list items are preserved, and task checkboxes align consistently between editing and reading modes. Completed parent tasks do not apply strikethrough styling to unchecked descendants.
  • Documentation
    • Clarified how task markers, Enter, and empty task items behave in Edit Mode.

RetriggerConfidence Score: 5/5

The PR appears safe to merge; no new actionable issue was identified.

Summary

The PR renders interactive task checkboxes in Edit Mode and adjusts task-list continuation and spacing. Since the previous review, it extends blank-separator preservation to continuation lines and adds a caret-geometry regression test.

📝 Walkthrough

Walkthrough

The editor renders task markers as interactive checkboxes, styles completed tasks, and handles Enter to continue or exit a task list. Tests cover checkbox state changes, list spacing, keyboard behavior, and alignment with read mode.

checked-item condition and eachLine call so cm-md-task-completed applies only to
the checked ListItem’s own lines; exclude nested ListItem ranges, preserving
unchecked child styling.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Render ordered task items as checkboxes.

For 1. [ ] Task, isTask is true, but this branch accepts only bullet markers. The ordered-marker branch also excludes tasks, so Edit Mode shows the raw ordered task marker instead of a checkbox. Accept ordered list markers here and apply the same marker support in continueTaskList so Enter handles ordered tasks consistently.
