Kyle Isom ba1571011a Fix critical bugs found in code audit
- MoveStrokesAction.undo(): was offsetting by (0,0), now restores
  original pre-move point data correctly
- Stroke commit flicker: new strokes render incrementally onto existing
  backing bitmap instead of triggering full redraw
- Selection state leak: view-side selection cleared on page navigation
  via onPageNavigated callback
- Initial page fallback: blank canvas prevented if initialPageId
  not found in DB — falls back to first page
- Arrow head Paint: preallocated reusable object, no per-call allocation
- Updated PROGRESS.md with audit findings and backup design notes

eng-pad

This is an Android app, targeting Android 11, and specifically the following two devices:

  1. The Supernote Manta (Android 11)
  2. The Daylight DC-1 (Android 13)

There are a few features it needs to have:

  1. It is organized around notebooks.
  2. A regular notebook's page size is 8.5 x 11 inches. A large notebook's size is 11 x 17 inches.
  3. The app features a grid of roughly 5 squares per inch. The grid is not visible on exported documents.
  4. The app should allow pinch to zoom in and out.
  5. There should be two pen sizes, corresponding roughly to a Muji gel ink ballpoint 0.38 or 0.5 pen.
  6. It should have the ability to erase, or to select-and-erase.
  7. It should have the ability to select and cut/move or copy/paste.
  8. The primary method of input is an EMR pen.
  9. The app needs to be able to export PDFs though the normal Android sharing mechanism (e.g. so docs can be exported to Dropbox).

The tech stack can be flexible. The safe default is Java, but if Kotlin or even Clojure or some other langauge makes more sense, it can be used.
