+# FFI Troubleshooting
+
+## UniFFI 版本
+
+本项目使用 UniFFI 0.31，采用 **UDL + proc-macro 混合模式**：
+- UDL（`zx_document.udl`）：定义类型和函数签名
+- `#[uniffi::export]` proc-macro：生成 C ABI 分发符号
+- `uniffi-bindgen`：生成 Swift/Kotlin 绑定代码
+
+## 常见问题
+
+### `No such module 'ZxDocumentRuntime'`
+
+**原因**：XCFramework 未正确添加到 Xcode 项目。
+
+**解决**：
+1. 确认 `bindings/ios/ZxDocumentRuntime.xcframework` 已生成
+2. 在 Xcode → Target → General → Frameworks 中添加
+3. 确保 Embed 设置为 `Do Not Embed`（静态库）
+
+### `Undefined symbol: _ffi_zx_document_ffi_*`
+
+**原因**：C ABI 符号未导出。proc-macro 生成的符号名称可能与链接器期望不一致。
+
+**解决**：
+1. 确认 `crates/zx_document_ffi/src/lib.rs` 中 `#[no_mangle] pub extern "C"` 函数存在
+2. 检查 Cargo.toml `crate-type = ["lib", "staticlib", "cdylib"]`
+3. 运行 `nm target/aarch64-apple-ios/release/libzx_document_ffi.a | grep ffi_` 验证符号
+4. 确认 UDL 中声明的函数与 `#[uniffi::export]` 函数名称一致
+
+### `Library not found for -lzx_document_ffi`
+
+**原因**：Library Search Paths 未设置。
+
+**解决**：
+1. Build Settings → Library Search Paths → 添加 `$(PROJECT_DIR)/bindings/ios`
+2. 或使用绝对路径指向 `.xcframework` 所在目录
+
+### UniFFI checksum mismatch
+
+**原因**：UDL 文件更新后未重新生成 Swift binding。
+
+**解决**：
+```bash
+uniffi-bindgen generate \
+    --language swift \
+    --out-dir bindings/ios/generated \
+    crates/zx_document_ffi/src/zx_document.udl
+```
+
+### `setup_scaffolding!()` not called
+
+**原因**：`uniffi::setup_scaffolding!()` 必须在 lib.rs 的第一行调用。
+
+**解决**：确认 `crates/zx_document_core/src/lib.rs` 第一行是 `uniffi::setup_scaffolding!();`
+
+### 新增类型/函数后 Swift 不可见
+
+**原因**：只在 Rust 侧添加了类型/函数，但未更新：
+1. UDL 文件声明
+2. FFI crate `pub use` 重导出
+3. Swift binding 重新生成
+
+**完整的 FFI 接入步骤**：
+```bash
+# 1. Rust 侧添加类型 + 函数 + UDL 声明
+# 2. FFI crate: pub use 重导出 + #[uniffi::export] 包装
+# 3. 重新生成 Swift
+uniffi-bindgen generate --language swift \
+    --out-dir bindings/ios/generated \
+    crates/zx_document_ffi/src/zx_document.udl
+# 4. 验证编译
+cargo build --release --target aarch64-apple-ios -p zx_document_ffi
+```
+
+### `cargo build` 目标平台不匹配
+
+**原因**：macOS 上构建 iOS 目标需要 Apple Silicon target。
+
+**解决**：
+```bash
+rustup target add aarch64-apple-ios aarch64-apple-ios-sim
+```
+
+### `infer` / `comrak` / `zip` crate 编译失败
+
+**原因**：某些 crate 在 iOS target 下有 C 依赖。
+
+**解决**：
+- `comrak`：需要启用 `--features` 中的 `onig` 或使用 `syntect` 后端
+- `zip`：纯 Rust，无特殊要求
+- 确保 `CC` 环境变量指向 Xcode toolchain
+
+### XCFramework 构建注意事项
+
+1. 必须分别编译 device 和 simulator 目标
+2. `lipo` 不需要（两个 .a 文件各自是 fat binary）
+3. header 文件由 `uniffi-bindgen` 生成：`bindings/ios/generated/zx_documentFFI.h`
+4. modulemap 文件创建：
+```
+framework module ZxDocumentRuntime {
+    header "zx_documentFFI.h"
+    export *
+}
+```
+
+### UDL 类型不支持
+
+**问题类型**：
+- `Vec<(String, &str)>` — 不支持 tuple
+- 泛型函数 — 不支持
+- 生命周期参数 — 不支持
+
+**解决**：在 FFI 层创建包装类型。例如 `search_pdf_text(&[(u32, &str)])` → FFI 包装为 `search_pdf_pages(Vec<u32>, Vec<String>)`。
+
+### Rust 与 iOS 持有引用
+
+UniFFI 生成的对象是 **值类型**（序列化跨 FFI 边界传递），不是引用类型。Rust 侧的 `Mutex` 保护全局状态，iOS 侧通过函数调用读写状态。
+
+### 验证清单
+
+- [ ] `cargo build --release --target aarch64-apple-ios` 通过
+- [ ] `cargo build --release --target aarch64-apple-ios-sim` 通过
+- [ ] `nm` 验证 C ABI 符号存在
+- [ ] Swift binding 生成并编译通过
+- [ ] XCFramework 包含 device + simulator slices
+- [ ] header + modulemap 正确
+- [ ] demo App 链接成功

-### 阅读事件集成
+### V2 阅读事件集成（推荐）
+
+V2 API 提供 session 管理、事件缓冲、ack 确认、crash recovery 等完整能力。
+
+#### 创建阅读目标和会话
 
 ```swift
-// Rust 生成事件 → Swift 缓存 + 上传
+// 1. 创建 ReadingMaterialRef（Rust 不存储 readingTargetType，iOS 上传时补充）
-class ReadingEventCollector {
+let material = ReadingMaterialRef(materialId: "mat_001")
-    private var buffer: [ReadingEvent] = []
 
-    func collect() {
+// 2. 启动阅读会话（返回 clientSessionId）
-        // Rust 侧事件暂存
+let timestamp = Int64(Date().timeIntervalSince1970 * 1000)
+let sessionId = try startReadingSessionV2(material: material, timestampMs: timestamp)
+```
+
+#### 推送 5 种事件
+
+```swift
+// MaterialOpened — 打开资料
+let opened = try pushMaterialOpenedV2(
+    sessionId: sessionId,
+    materialId: "mat_001",
+    timestampMs: now()
+)
+
+// PositionChanged — 位置变化
+let pos = ReadingPosition.markdown(blockId: "intro", scrollProgress: 0.25)
+let changed = try pushPositionChangedV2(
+    sessionId: sessionId,
+    materialId: "mat_001",
+    position: pos,
+    timestampMs: now()
+)
+
+// Heartbeat — 心跳（含 activeSecondsDelta）
+let hb = try pushHeartbeatV2(
+    sessionId: sessionId,
+    materialId: "mat_001",
+    activeSecondsDelta: 15,
+    position: nil,
+    timestampMs: now()
+)
+
+// MarkedAsRead — 标记已读
+let mar = try pushMarkedAsReadV2(
+    sessionId: sessionId,
+    materialId: "mat_001",
+    timestampMs: now()
+)
+
+// MaterialClosed — 关闭资料
+let closed = try pushMaterialClosedV2(
+    sessionId: sessionId,
+    materialId: "mat_001",
+    activeSecondsDelta: 0,
+    timestampMs: now()
+)
+```
+
+#### Export + Ack 流程
+
+```swift
+// 1. 导出待上传事件（标记为 Exported）
+let events = exportPendingEventsV2(limit: 100, timestampMs: now())
+
+// 2. 构造上传请求（iOS 补充 readingTargetType/platform/appVersion/timezone）
+let uploadItems = events.map { event in
+    ReadingEventUploadItem(
+        eventId: event.eventId,
+        clientSessionId: event.clientSessionId,
+        materialId: event.materialId,
+        eventType: event.eventType,
+        position: event.position,
+        activeSecondsDelta: event.activeSecondsDelta,
+        clientTimestampMs: event.timestampMs,
+        sequence: event.sequence,
+        // iOS 补充字段
+        readingTargetType: getTargetType(for: event.materialId),
+        platform: "ios",
+        appVersion: Bundle.main.appVersion,
+        clientTimezoneOffsetMinutes: Int(TimeZone.current.secondsFromGMT() / 60)
+    )
 }
 
-    func flush() {
+// 3. 上传到 API
-        // POST buffer → /reading/events
+api.uploadEvents(uploadItems) { result in
-        // clear buffer
+    switch result {
+    case .success:
+        // 成功后 ACK（从 buffer 移除）
+        let ids = events.map(\.eventId)
+        ackEventsV2(eventIds: ids)
+    case .failure:
+        // 失败标记为 Failed（下次 export 重试）
+        let ids = events.map(\.eventId)
+        markEventsFailedV2(eventIds: ids)
     }
 }
 ```
 
+#### App 启动恢复
+
+```swift
+// App 启动时调用，恢复上次未 ack 的事件
+func applicationDidFinishLaunching() {
+    reloadStaleEventsV2() // 内部 Pending/Exported→Pending，可重新 export
+}
+```
+
+#### 搜索和笔记锚点
+
+```swift
+// 1. 解析 Markdown
+let blocks = try parseMarkdown(content: mdContent)
+
+// 2. 搜索
+let results = searchMarkdownBlocks(blocks: blocks, query: "keyword")
+
+// 3. 从搜索结果创建笔记锚点
+if let firstResult = results.first {
+    let anchor = createNoteAnchorFromSearch(
+        materialId: "mat_001",
+        result: firstResult
+    )
+    // anchor 包含 materialId/blockId/pageNumber/chapterId/snippet
+}
+
+// 4. 从阅读位置创建锚点
+let pos = ReadingPosition.pdf(pageNumber: 3, pageProgress: 0.5, overallProgress: 0.1)
+let anchor = createNoteAnchor(materialId: "mat_001", position: pos)
+// → NoteAnchor.pdfPage(materialId: "mat_001", pageNumber: 3, positionSnapshot: pos)
+
+// 5. 从锚点恢复阅读位置
+if let restored = restorePositionFromAnchor(anchor: anchor) {
+    // navigate to restored position
+}
+
+// PDF 搜索
+let pages = searchPdfPages(
+    pageNumbers: [1, 2, 3],
+    pageTexts: ["page 1 text", "page 2 text", "page 3 text"],
+    query: "keyword"
+) // → [SearchResult] with page_number
+
+// EPUB 搜索
+let chapters = searchEpubChaptersFfi(
+    chapterIds: ["intro", "ch1"],
+    chapterTexts: ["Welcome", "Content with keyword"],
+    query: "keyword"
+) // → [SearchResult] with chapter_id
+```
+
+#### PDF/EPUB 元数据
+
+```swift
+// PDF

+# ReadingEvent V2 协议
+
+## 概述
+
+V2 阅读事件协议定义了一套完整的学习行为采集框架：**阅读会话 → 事件生成 → buffer 暂存 → export 导出 → ack 确认**。
+
+与 V1 的区别：
+- V1：无 session，无 ack，无 id 追踪
+- V2：session 管理 + 全局事件 buffer + export/ack 确认 + crash recovery
+
+## 核心概念
+
+### ReadingSessionV2
+
+一次阅读会话。iOS App 一次打开资料即创建一个 session。
+
+```rust
+pub struct ReadingSessionV2 {
+    pub client_session_id: String,   // UUID v4，会话标识
+    pub material: ReadingMaterialRef, // 被阅读的资料
+    pub started_at_ms: i64,          // 会话开始时间
+    pub last_event_at_ms: i64,       // 最后一次事件时间
+    pub next_sequence: u64,          // 下一个事件序号（从 1 开始）
+    pub total_active_seconds: u32,   // 累计活跃阅读秒数
+    pub last_position: Option<ReadingPosition>, // 最后位置
+    pub status: ReadingSessionStatus, // Active/Paused/Closed
+}
+```
+
+#### 生命周期
+
+```
+start → Active → (pause → Paused → resume → Active)* → close → Closed
+```
+
+- **Active**：可推送任意类型事件
+- **Paused**：仅可推送 delta=0 事件（PositionChanged/MarkedAsRead）
+- **Closed**：不可推送事件，不可重新打开
+
+### ReadingMaterialRef
+
+```rust
+pub struct ReadingMaterialRef {
+    pub material_id: String,
+}
+```
+
+Rust 不存储 `readingTargetType`（如 knowledge/material/course/note），由 iOS 上传时补充。
+
+### ReadingEventV2
+
+```rust
+pub struct ReadingEventV2 {
+    pub event_id: String,            // UUID v4，全局唯一事件 ID
+    pub client_session_id: String,   // 关联的会话 ID
+    pub material_id: String,         // 资料 ID
+    pub event_type: ReadingEventTypeV2, // 事件类型
+    pub position: Option<ReadingPosition>, // 阅读位置（camelCase JSON）
+    pub active_seconds_delta: u32,   // 距上次事件的活跃秒数
+    pub timestamp_ms: i64,           // 客户端时间戳
+    pub sequence: u64,               // session 内递增序号（1-based）
+}
+```
+
+#### eventType 取值
+
+| Rust | API JSON |
+|------|----------|
+| `MaterialOpened` | `material_opened` |
+| `MaterialClosed` | `material_closed` |
+| `PositionChanged` | `position_changed` |
+| `Heartbeat` | `heartbeat` |
+| `MarkedAsRead` | `marked_as_read` |
+
+#### activeSecondsDelta 规则
+
+| 事件 | delta |
+|------|-------|
+| MaterialOpened | 0 |
+| PositionChanged | 0 |
+| MarkedAsRead | 0 |
+| Heartbeat | ActiveTimeTracker.tick() 返回值 |
+| MaterialClosed | ActiveTimeTracker.close() 返回值 |
+
+### ActiveTimeTracker
+
+iOS 控制 tick 节奏，Rust 计算 delta：
+
+```
+start(ts) → tick(ts+15s) → tick(ts+30s) → close(ts+43s)
+             delta=15       delta=15        delta=13
+```
+
+- 暂停时不累计时间
+- 时间倒退返回 0
+- 余数毫秒累积到下次 tick
+
+### EventBuffer 状态机
+
+```
+              push
+                │
+                ▼
+          ┌─ Pending ──┐
+          │             │
+     export()      reload_stale()
+          │             │
+          ▼             │
+        Exported ───────┘
+          │
+    ┌─────┴─────┐
+    │           │
+  ack()    mark_failed()
+    │           │
+    ▼           ▼
+ (removed)   Failed
+                │
+           export() ──→ 重试
+```
+
+- **Pending**：新事件，等待导出
+- **Exported**：已导出，等待 ack。crash 后 `reload_stale_events()` 恢复为 Pending
+- **Failed**：上传失败，下次 export 重试
+- **Ack 后删除**：从 buffer 移除
+
+### 溢出驱逐
+
+Buffer 容量：1000 条。满时驱逐顺序：
+1. Failed（最早失败的）
+2. Exported（最早导出的）
+3. 最早 Pending
+
+## API 上传字段映射
+
+| Rust ReadingEventV2 | API ReadingEventUploadItem | 来源 |
+|---------------------|---------------------------|------|
+| event_id | eventId | Rust UUID |
+| client_session_id | clientSessionId | Rust UUID |
+| material_id | materialId | Rust 保存 |
+| event_type | eventType | Rust→snake_case |
+| position | position | Rust（camelCase JSON，clamped） |
+| active_seconds_delta | activeSecondsDelta | ActiveTimeTracker |
+| timestamp_ms | clientTimestampMs | Rust |
+| sequence | sequence | session 内递增 |
+| — | readingTargetType | **iOS 补充** |
+| — | platform | **iOS 补充** |
+| — | appVersion | **iOS 补充** |
+| — | clientTimezoneOffsetMinutes | **iOS 补充** |
+
+## iOS 上传流程
+
+```
+1. Rust export_pending_events_v2(limit, timestamp) → Vec<ReadingEventV2>
+2. iOS 遍历事件，补充 readingTargetType/platform/appVersion/timezone
+3. iOS 构造 API 请求体
+4. POST /reading/events
+5. 成功 → Rust ack_events_v2(eventIds)
+6. 失败 → Rust mark_events_failed_v2(eventIds)
+7. App 启动 → Rust reload_stale_events_v2()
+```
