1ee512dce1 harden(ai): LLMSession 取消时跳过 MLX.GPU.synchronize 
按 code quality review(P0)反馈,for-await 因 Task.isCancelled
退出时,GPU.synchronize() 不必执行——这是一个阻塞的 GPU 同步操作,
取消场景下属浪费。

W3 引入"用户取消推理"UI 时会更频繁触发此路径。

P1/P2 留待 W3 退散考量:
- decodeRate 用窗口平均(目前是累积)
- AIRuntime 持具体 LLMSession 类型,W3 抽 protocol 做 mock
- prompt 空字符串守门
- Float(0.6) 风格

ad1b045e12 feat(ai): LLMSession 接 MLX-Swift,跑 Qwen3-1.7B 流式生成 
按 W2 plan Task 6 + docs/superpowers/notes/2026-05-25-mlx-api-corrections.md
落地 LLM 推理底座:

- actor LLMSession 包装 MLXLLM.ModelContainer
- load(folderURL:) 用 ModelConfiguration(directory:) + LLMModelFactory.shared.loadContainer
- generate(prompt:maxTokens:) 返回 AsyncThrowingStream<TokenChunk, Error>
- 内部 container.perform { (context: ModelContext) in ... } 拿到模型上下文
- UserInput → processor.prepare → MLXLMCommon.generate(顶层函数, AsyncStream)
- Generation switch 穷举 3 个 case(chunk / info / toolCall)
- maxTokens 通过 GenerateParameters 传递,温度 0.6 topP 0.9
- 取消传播:continuation.onTermination 同步 task.cancel()
- 每 chunk yield 时计算 tok/s decodeRate

API 基线:mlx-swift-examples tag 2.29.1, commit 9bff95ca。

需用户手动:
1. Xcode 把 LLMSession.swift 拖入 体己 target (AI group)
2. ⌘B 验证 AIRuntime 不再报 "Cannot find LLMSession"
3. 把 ~/tiji-models/Qwen3-1.7B-4bit/ 拷到模拟器沙盒 Application Support/Models/
4. Task 7 (DebugAIRunner) 才能跑通

ef0fbeac97 fix(ai,persistence): ModelStore + FileVault 标 @unchecked Sendable 
Xcode 26 默认开启 Swift 6 严格并发检查。AIRuntime(actor)
调用 ModelStore.shared.isReady(...) 跨 actor 边界,因 ModelStore
非 Sendable 而编译报错"Expression is 'async' but is not marked
with 'await'; this is an error in the Swift 6 language mode"。

两个类的内部状态只读(rootURL: let),方法只做线程安全的
filesystem I/O,符合 Sendable 语义,标 @unchecked Sendable
即可,不必加锁或重构。

修复目标错误:
- AIRuntime.swift:48 - guard ModelStore.shared.isReady(.llm) ...
- 后续 CaptureService 调 FileVault.shared.writeJPEG 同样路径

不影响:
- HomeView/B5ResultView 里 Text "+" 的 macOS 26.0 deprecation 是
  warning,不阻塞 build,留待 UI polish 周清理

771b28e7ef fix(ai): ModelKind rawValue 改为真实 HF mlx-community 仓库名 
实际查 HuggingFace 后,mlx-community 下的仓库名:
- Qwen3-1.7B-4bit(不是 Qwen3-1.7B-MLX-4bit)
- Qwen2.5-VL-3B-Instruct-4bit(VL 模型带 Instruct 后缀)

改动:
- ModelKind.llm/vl rawValue 改名,这也是沙盒 Models/ 下的子目录名
- 加 huggingFaceRepo computed:"mlx-community/\(rawValue)"
- CLAUDE.md §2 表格补 HF 仓库 ID
- spec §2.2 模型来源行修正

W2 plan 中的下载脚本已陈旧(用了 huggingface-cli + 错名),
W2 retro 时会修正。

e7cdb45472 harden(ai): AIRuntime 去掉冗余 weak self,prepare loading 路径加注释 
按 code quality review 反馈(2×P0):
- generate() 的 Task 闭包不再 [weak self];actor 单例 strong capture
  没有循环引用风险,且避免 Swift 5.10+ weak-on-actor 警告
- prepare() 的 case .loading: return 加注释说明这是有意设计,
  调用方需轮询或显示 loading UI(W3 引入 prepare 队列优化)

4dcd951821 feat(ai): add AIRuntime actor skeleton + TokenChunk 
按 W2 plan Task 5 落地推理串行化骨架:
- TokenChunk: Sendable struct (text + decodeRate tok/s)
- AIRuntime: actor 单例
  - Status: notReady / loading / ready / error(msg)
  - prepare() async throws: 幂等加载,失败回滚 status
  - generate(prompt:maxTokens:) -> AsyncThrowingStream: 流式输出
    跨 actor 边界用 snapshot 模式捕获 self.status/llmSession
  - lastDecodeRate: 给 UI 顶部条 / Live Activity 取
- AIRuntimeError: LocalizedError, 三种 case

WIP: Build will fail until Task 6 lands LLMSession (intentional).

d40cb7d1e0 harden(ai): ModelStore seedFromBundle 在 DEBUG 报错,加空目录测试 
按 code quality review 反馈:
- seedFromBundle 找不到 bundle 资源时,DEBUG 下 assertionFailure 提示
  target membership(release 仍静默 return),避免 W6 启用时排查困难
- 补 totalBytesReturnsZeroWhenFolderMissing 测试,覆盖 folder 不存在时
  enumerator 为 nil 的 guard 路径

ad6fb660f0 feat(ai): add ModelStore with path management and bundle seed 
按 W2 plan Task 4 落地模型路径管理:
- ModelKind enum: llm (Qwen3-1.7B-MLX-4bit) / vl (Qwen2.5-VL-3B-MLX-4bit)
- 用 config.json 作为 sentinel 判定模型是否就绪
- isReady / localURL / totalBytes 三个查询接口
- seedFromBundle(_:) 占位:Demo 现场预装模型旁路(W6 启用)
- shared 单例用 Application Support/Models/

测试 3 条:fresh / mark-ready / totalBytes,均用临时目录隔离 + defer cleanup。

注:.swift 文件需用户在 Xcode 拖入 target,⌘U 确认绿后 amend build commit。

0739ccea2b harden(persistence): FileVault path traversal guard + error unification 
按 code quality review 反馈(P0 + 4×P1):
- 加 resolveSafePath() 拒绝 / 和 .. 并验证 hasPrefix(rootURL)
- loadImage/remove 统一抛 FileVaultError(readFailed/removeFailed)
- 删除测试 struct 上多余的 @MainActor
- 每个 @Test 加 defer cleanup,不泄漏 temp 目录
- 测试图片改用生成 16x16 红色,不依赖 SF Symbol

d704a9eb78 feat(persistence): add FileVault with complete file protection 
按 W2 plan Task 3 落地原图加密存储:
- writeJPEG / loadImage / remove / wipe 四个核心操作
- Application Support/Vault/ 目录全程 .completeFileProtection
- 文件写入用 .completeFileProtection options(双保险)
- FileVault(rootURL:) 注入便于测试隔离
- shared 单例用真实 App Support 路径

测试 3 条:roundtrip / remove / wipe。

注:.swift 文件需用户在 Xcode 拖入 target(Persistence group + 体己Tests),
之后 ⌘U 跑测试,若全绿再 amend 提交 .pbxproj。

- Report 加 indicators / assets @Relationship(cascade)
- DiaryEntry 加 tags
- 新增 @Model Asset (原图元数据)
- 新增 @Model ChatTurn (问答历史 + 引用)
- TijiApp Schema 加入新 model

注:Schema 破坏性变更,用户需在 Xcode 里 Erase Simulator
后重启 App。

c050865db5 feat(ui): UI 骨架基线 — 3 Tab + RecordSheet + Quick/Archive 流程占位 
替换 Xcode 默认模板:
- 删除 ContentView/Item/__App
- 新增 App/TijiApp(SwiftData ModelContainer)、RootView(3 Tab + RecordSheet)
