PencilKit & PaperKit Q&A

I'd like to know if there are any official, out-of-the-box tools available for handwriting and PaperKit that can help lower the input barrier for older adults and users with disabilities.

Does PaperKit expose the underlying PKDrawing / PKStroke / PKStrokePath data in a way that preserves stroke order, point sequence, and per-point properties, or is it primarily intended for markup persistence and rendering?

What is the recommended way to analyze PencilKit strokes in near real time without interfering with Apple Pencil latency? Should analysis occur only after canvasViewDrawingDidChange, after each stroke ends, or through lower-level touch handling?

Will the sample code of the "Unwrap PaperKit" session be made available?
