# Phase 7 Verification

## Result

Passed.

## What Was Verified

- HTML/CSS pagination semantics now survive the native text pipeline as explicit attributed-string metadata.
- Paginator and page metadata consume those semantics and expose them in break reasons and diagnostics.
- Demo startup validation surfaces semantic-closure evidence for a native reflowable sample book.

## Evidence

- `build_sim` for `ReadViewDemo` succeeded after the semantic extraction and layouter-consumption changes.
- `build_run_sim` for `ReadViewDemo` succeeded on iPhone 17 (iOS 26.5 simulator).
- Runtime log surfaced:
  - `属性闭环诊断：宝山辽墓材料与释读 · 章节 10 · block kinds [attachment,paragraph] · placements [inline,centered] · block kinds: attachment`
  - `分页诊断：宝山辽墓材料与释读 · 章节 10 · attachment 页 54 · semantic break 页 57 · block kinds [attachment,paragraph] · placements [inline,centered] · reasons [attachmentBoundary:31, blockBoundary:26, frameLimit:17, chapterEnd:4] · page break: blockBoundary`

## Residual Risk

- Current semantic extraction is intentionally conservative and heuristic-driven; future EPUB variants may require additional tag/class/style mappings in Phase 8.
- The sample evidence currently proves attachment and paragraph semantics clearly; richer code/list/table/blockquote samples should continue to be exercised as later phases tighten quality and automation.
