You are building an outline while reading a textbook page by page.  
You already know what chapters and topics have been identified so far, and you’re about to analyze one new page.

  
Page Number: $page  

Current page:
$target.pagetext

Your job:
1. Detect if this page begins a **new chapter** or **topic**.  
2. Note any **concepts** that might become quiz questions.  
3. Keep the running list of chapters and topics up to date.  
4. Generate one **summary sentence** describing what changed.  
5. Return valid JSON for the `reviewpage` function — include an `events` array if you detect transitions (like `chapterstart`, `topicstart`, `questioncandidate`).

Do not repeat prior material or hallucinate new content. Focus only on what is visible here.
