# 04-02 Summary

## Outcome

Wave 2 tightened native location, highlight, selection, search, and TOC compatibility around the Phase 3 offset contract.

- `normalizedTextSelection` now preserves exclusive end semantics more carefully when rebuilding progressions from `RDEPUBTextOffsetRangeInfo`
- Native highlight filtering now compares normalized hrefs, reducing mismatch risk after resolver normalization
- Search page lookup now prefers exact `rangeLocation` offset matching before falling back to progression-based page resolution

## Compatibility

- `RDEPUBTextOffsetRangeInfo` remains the native persisted range format
- `RDEPUBTextContentView` still derives visible overlap from `pageStartOffset` / `pageEndOffset`
- No page-local-only identifier replaced the absolute chapter offset contract
