# 07-02 Summary

- Taught `RDEPUBTextLayouter` to consume semantic hints and emit `semanticBoundary` breaks when explicit page-break or avoid-break rules should influence pagination.
- Expanded page metadata and layout frames to retain block kinds, semantic hints, and attachment placements alongside the existing attachment and break diagnostics.
- Propagated the richer pagination diagnostics through `RDEPUBTextBookBuilder` and `RDPlainTextBookBuilder`, so chapter summaries can now explain attachment-heavy and block-sensitive pagination behavior.

## Verification

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