Review https://excalidraw.com/ with three quick checks: load the public editor, draw a rectangle with the text ‘Scout check’ inside it, and verify undo then redo restores the drawing. Use an empty canvas; leave any existing drawing untouched. Capture screenshots and a short walkthrough with pass/fail evidence. Keep this review brief and finish after those checks. Do not sign in, create an account, invite anyone, or publish a collaboration link.
I’ll use the public editor only, confirm the canvas is empty before drawing, then verify the undo/redo state changes without signing in or sharing.
All three checks passed on [excalidraw.com](https://excalidraw.com/): 1. Loaded the public editor on an empty canvas. 2. Drew a rectangle containing the exact text “Scout check.” 3. Verified that Undo removed the latest drawing state and Redo restored it. Screenshots and the short walkthrough were saved. No sign-in, account creation, invitation, or collaboration link was used.
