# 04-03 Summary

## Outcome

Wave 3 validated repagination and semantic location restore with real sample books.

- The demo now reports a restore diagnostic alongside the pagination diagnostic
- Validation rebuilds native text books with a larger font/line spacing and a theme-only style change, then checks whether the same semantic location still resolves correctly
- Runtime evidence confirmed stable href restoration and theme-stable page mapping on the sampled reflowable EPUB

## 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`
- `恢复诊断：宝山辽墓材料与释读 · base 39 · font-shift 44 · theme-stable yes · href-stable yes · progression-delta 0.004`

This shows the native reader backend can repaginate to a different page number under font changes while preserving the same semantic reading location.
