# 03-03 Summary

## Outcome

Wave 3 exposed real-book pagination diagnostics and confirmed that offset-compatible highlight/search presentation stayed intact.

- Added builder-level `RDEPUBTextChapterPaginationDiagnostic`
- `RDEPUBTextBookBuilder` now records `lastBuildPaginationDiagnostics`
- `ReadViewDemo/ViewController.swift` reports pagination evidence from sample EPUBs in UI/runtime logs
- `RDEPUBTextContentView.swift` still computes highlight/search overlap from absolute `pageStartOffset` / `pageEndOffset`, now via an explicit helper

## Demo Evidence

Runtime log from the simulator:

- `EPUB 资源验证：2/2 通过`
- `分页诊断：宝山辽墓材料与释读 · 章节 10 · attachment 页 54 · semantic break 页 57 · reasons [attachmentBoundary:31, blockBoundary:26, frameLimit:17, chapterEnd:4] · page break: blockBoundary`

This confirms the stronger paginator is active on real EPUB content and not silently falling back to pure visible-range slicing.
