# Phase 01: Current Engine Boundaries Verification Report
|
|
|
|
**Phase Goal:** 把“当前旧引擎是什么、哪些能力必须保留、哪些路径绝对不能动”说清楚，形成直接重构旧引擎的实施基线。
|
|
**Verified:** 2026-05-21T13:59:30Z

|
**Status:** passed

## Goal Achievement

|
### Observable Truths
|
|
|
|
| # | Truth | Status | Evidence |
|
|
|---|-------|--------|----------|
|
|
| 1 | 能准确描述当前 `.textReflowable` 的真实调用链与数据流 | ✓ VERIFIED | `.planning/phases/01-current-engine-boundaries/01-reflowable-audit.md` 明确给出 `RDURLReaderController -> RDEPUBReaderController -> RDEPUBTextBookBuilder -> RDEPUBDTCoreTextRenderer -> ss_pageRanges(size:) -> RDEPUBTextContentView -> RDReaderView` 链路。 |
|
|
| 2 | Fixed Layout / 交互式 EPUB 的 `WKWebView` 边界不含糊，且不被纳入本次重构 | ✓ VERIFIED | 审计文档 “What Still Uses WKWebView” 与策略文档 “`WKWebView` retention boundary” 均列出 `webFixedLayout`、`webInteractive`、`RDEPUBWebView+FixedLayout.swift`、`RDEPUBWebView+Reflowable.swift`、`RDEPUBPaginator.swift`。 |
|
|
| 3 | 当前翻页代码（`RDReaderView`）被明确排除在本次改造范围外 | ✓ VERIFIED | 两份文档都把 `RDReaderView` 记录为稳定外壳；策略文档明确列出“修改 `RDReaderView` 的外部容器契约”为拒绝项。 |
|
|
| 4 | 输出一份针对“旧引擎直接演进”的重构切入策略，而不是双引擎方案 | ✓ VERIFIED | `.planning/phases/01-current-engine-boundaries/01-refactor-entry-strategy.md` 明确给出 Phase 2 / 3 / 4 顺序和 “direct evolution, not parallel engine” 结论。 |
|
|
|
|
**Score:** 4/4 truths verified
|
|
|
|
### Required Artifacts
|
|
|
|
| Artifact | Expected | Status | Details |
|
|
|----------|----------|--------|---------|
|
|
| `.planning/phases/01-current-engine-boundaries/01-reflowable-audit.md` | 当前 native reflowable 调用链与边界审计 | ✓ EXISTS + SUBSTANTIVE | 文档内容覆盖入口、分流、渲染、分页、展示、兼容层和排除项。 |
|
|
| `.planning/phases/01-current-engine-boundaries/01-refactor-entry-strategy.md` | 旧引擎直接演进切入策略 | ✓ EXISTS + SUBSTANTIVE | 文档内容覆盖 capability mapping、phase sequencing、兼容面和非目标。 |
|
|
| `.planning/phases/01-current-engine-boundaries/01-01-SUMMARY.md` | 审计计划执行总结 | ✓ EXISTS + SUBSTANTIVE | 记录 Wave 1 产出与决策。 |
|
|
| `.planning/phases/01-current-engine-boundaries/01-02-SUMMARY.md` | 策略计划执行总结 | ✓ EXISTS + SUBSTANTIVE | 记录 Wave 2 产出与后续 readiness。 |

**Artifacts:** 4/4 verified

### Key Link Verification
|
|
|
|
| From | To | Via | Status | Details |
|
|
|------|----|----|--------|---------|
|
|
| `01-reflowable-audit.md` | current source files | file-path evidence | ✓ WIRED | 审计文档逐段引用 `RDEPUBReaderController.swift`、`RDEPUBTextBookBuilder.swift`、`RDEPUBParser+ReadingProfile.swift`、`RDReaderView.swift`。 |
|
|
| `01-refactor-entry-strategy.md` | `01-reflowable-audit.md` | strategy derives from audit findings | ✓ WIRED | 策略文档直接以审计结论为 Phase 2/3/4 输入，避免重新定义边界。 |
|
|
| Phase 1 summaries | roadmap progress | `roadmap.update-plan-progress 01` | ✓ WIRED | `ROADMAP.md` 已显示 Phase 1 为 `2/2 | Complete | 2026-05-21`。 |
|
|
| Phase 1 requirement | requirements traceability | `requirements.mark-complete COMP-02` | ✓ WIRED | `REQUIREMENTS.md` 中 `COMP-02` 已标记为 complete。 |
|
|
|
|
**Wiring:** 4/4 connections verified
|
|
|
|
## Requirements Coverage
|
|
|
|
| Requirement | Status | Blocking Issue |
|
|
|-------------|--------|----------------|
|
|
| COMP-02: Fixed Layout EPUB 与交互式 EPUB 继续使用 `WKWebView`，行为不因本次改造产生回归 | ✓ SATISFIED | - |
|
|
|
|
**Coverage:** 1/1 requirements satisfied
|
|
|
|
## Anti-Patterns Found
|
|
|
|
None
|
|
|
|
## Human Verification Required
|
|
|
|
None — all Phase 1 deliverables are documentary and verifiable by source/document inspection.
|
|
|
|
## Gaps Summary
|
|
|
|
**No gaps found.** Phase goal achieved. Ready to proceed.
|
|
|
|
## Verification Metadata
|
|
|
|
**Verification approach:** Goal-backward, using roadmap success criteria plus plan must-haves
|
|
**Must-haves source:** Phase 1 PLAN frontmatter + ROADMAP success criteria
|
|
**Automated checks:** file existence, grep coverage, roadmap progress sync
|
|
**Human checks required:** 0
|
|
**Total verification time:** ~2 min
