Problem: the detail buffer rendered metadata as read-only virtual text overlays. Users could not edit status, priority, category, due, or recurrence from the detail view. Solution: render frontmatter as real `Key: value` text lines highlighted via extmarks. On `:w`, `parse_detail_frontmatter()` validates every field (status, priority bounds, `resolve_date`, `recur.validate`) and aborts with `log.error()` on any invalid input. Removing a line clears the field; editing the `# title` updates the description.
