+## 问题 / 背景
+
+可信 Catalog 与本地状态已经可用，但两个客户端仍只显示空 AppShell。主视图需要在不把磁盘/网络 IO 放进 Layout 的前提下，支持数百项、搜索、分类和全部/已安装/可更新切换；若控件按列表索引保存，筛选或排序后点击状态会错位。
+
+## 方案
+
+1. 在 `core/application` 建立共享、无 IO 的 CatalogListModel，列表项使用稳定软件 ID；支持名称/ID/tag 搜索、分类集合与 all/installed/updates 三种视图。
+2. 过滤结果保持 Catalog 原顺序；查询和分类变化不重建源数据，Gio 只消费当前可见切片。
+3. modern/win7 分别实现 Gio AppShell：顶部搜索与分类、左侧视图切换、中部惰性 `layout.List`、有帮助文案的空状态和底部状态栏。
+4. 每个 AppRow 的 Clickable 按软件 ID 存入 map，不按可见索引；每帧先 drain 点击，再执行布局。
+5. 使用扁平、高对比、44dp 最小交互目标和 4/8dp 间距体系；Legacy 减少装饰但保持同一语义。
+6. 测试共享筛选规则、ID 控件稳定性，并用数百项 + 有限 viewport 证明 layout.List 只布局可见行。
+
+## 验收要点
+
+- 搜索覆盖名称、ID 与 tags，忽略大小写和首尾空白。
+- 分类筛选与 all/installed/updates 视图可组合；无结果显示清晰空状态。
+- 两个 Gio 版本均使用惰性 layout.List；500 项在有限 viewport 中不会布局全部行。
+- 行控件状态按 app ID 保持，过滤/切换视图后不串行。
+- Layout 代码不读文件、不访问网络、不计算哈希。
+- modern 与 win7 UI 测试/构建、Go 1.20 core vet/test、完整双目标闸门和治理校验通过。
+
+## 边界（不改什么）
+
+- 不实现详情弹层与图标缓存（T-204）。
+- 不发起下载、安装、启动或真实 Catalog 网络装配；主操作仅展示当前状态语义。
+- 不实现下载中/最近使用视图或多标签复选；路线图 MVP 本任务只冻结 all/installed/updates。
+- 不添加动画、阴影、emoji 图标或新 UI 依赖。
+
+## 协作约束
+
+未启用 Gitea；本任务在 `agent/codex/T-203` 分支串行执行。`ui-ux-pro-max` 的本轮约束是高对比扁平界面、可见焦点/空状态、44dp 目标、虚拟化 50+ 项和键盘顺序与视觉顺序一致。
+
+## 执行记录
+
+- 2026-07-16:按 `ui-ux-pro-max` 先生成 SoftBox 设计系统并检索虚拟列表、键盘导航、空状态与焦点规则；最终采用高对比浅色、扁平无阴影、4/8dp 间距、44dp 控件和明显 Legacy 标识。
+- 2026-07-16:在 `core/application` 建立无 IO `CatalogListModel`；搜索覆盖名称/ID/tags，单分类与 all/installed/updates 可组合，过滤保持 Catalog 原顺序并保存 selected app ID。
+- 2026-07-16:modern Gio v0.10.1 与 win7 Gio v0.6.0 分别实现搜索栏、横向分类、左侧视图切换、惰性软件列表、状态/原因文案、两类空状态和恢复筛选操作。
+- 2026-07-16:Editor/按钮/软件行均提供键盘焦点反馈；自定义行补充 semantic button/description，未使用 emoji、阴影或额外 UI 依赖。
+- 2026-07-16:行 Clickable 以软件 ID 为键保存；筛选与 Catalog 快照更新后同 ID 控件保持原实例，移除的软件控件被释放。
+- 2026-07-16:两个适配各用 500 项 + 有限 viewport 测试证明 `layout.List` 只布局可见子集；空 AppShell 仍保持窗口尺寸测试。
+- 2026-07-16:同步 `docs/routes.md`、`docs/04-architecture.md` 与 `docs/current-state.md`；真实 Catalog 网络/密钥装配仍保持在 Layout 外。
+- 定向验证通过:`go -C core test -count=1 ./application`、modern/win7 `go test -count=1 ./ui/gio`。
+- Layout IO 扫描通过:`rg` 检查两个 `ui/gio` 下无 `os`、`net/http`、文件读写、filepath 或 sha256 调用。
+- 完整验证通过:`./scripts/verify_phase0.ps1`，包含 Go 1.20.14 core vet/test、治理/边界/版本检查及 modern/win7 双目标测试与构建。
+- 提交前检查通过:`git diff --check`。
+- 工作区中的未跟踪 `soft_quay.code-workspace` 与本任务无关，已保留且未纳入提交。
