ProseMirror

Type: editor engine reference

ProseMirror is the main overlay-discipline benchmark in this research lane.

Why it matters

• strongest reference for mapped decoration data
• strongest reference for bookmark-style durable anchors
• strongest pressure against callback-only decoration APIs

Strongest local evidence

• ../prosemirror/view/src/decoration.ts
• ../prosemirror/view/src/viewdesc.ts
• ../prosemirror/state/src/selection.ts

Limits

• not the main React DX benchmark
• not the right lower-bound reference for lightweight surfaces
• still the harder benchmark on explicit document-view diff discipline
