# 06-01 Summary

- Added `RDEPUBTextPageGeometry` value types and threaded page geometry through `RDEPUBTextLayoutFrame`, `RDEPUBTextPage`, and both text book builders.
- Geometry now comes from CoreText line offsets instead of inferred page offsets, while `pageStartOffset`, `pageEndOffset`, `fragmentOffsets`, and `RDEPUBTextOffsetRangeInfo` semantics remain unchanged.
- Added reusable page query helpers for range-to-rect and rect or point back to absolute text ranges.

## Verification

- `build_sim` for `ReadViewDemo` on iOS Simulator succeeded on 2026-05-22.
