       是 module_85196 的内部函数、不导出，18334 也不直接读 CC 槽位，
       说明转换经 DI 服务接口完成；下一步用别名表追该接口的实现方法。
+  - 物品目录（`App/Session/ItemCatalog.kt`）：
+    - 结论修正：抓包里这 30029 条未覆盖 Pt 项**不是用户状态**，而是静态物品表
+      （1371 个物品对象 + 515 个装置对象），原包也不把它放进 Redux，而是由服务按需读取。
+    - 容器形态（`names/model_registry.json` + 抓包实测）：`pt.Items` 按 `Id == 0` 的对象标记分组，
+      标记项的值就是 ObjectId；组内按 modelId 建索引。物品组通常是
+      `CountableItemCC, ItemPropertiesCC, ItemSaleByKitCC, BuyableCC, TimePeriodModelCC,
+      ItemModelCC, ItemRarityCC, DescriptionModelCC, ItemCategoryCC, PremiumItemCC,
+      ItemViewCategoryCC, DescriptionMediaCC, VisibleCC`；装置组换成
+      `DevicePropertiesCC + TemporaryItemCC`。
+    - `CC → GarageItemObject` / `GarageDeviceObject` 的字段顺序取自 module_18334 的
+      `S$`（物品）与 `gct`（装置）的构造函数实参，token → 模型类由跨模块别名表反查，逐条登记在文件头。
+    - `SessionRouter` 在 Pt 分支先调 `Catalog.Ingest`，被目录吸收的项不再计入未覆盖：
+      抓包实测 **物品 1399 / 装置 516 / 吸收 27826 项**，未覆盖从 30029 降到 2203
+      （余下主要是 methodId 级未覆盖、`0` 对象标记、以及 ResistancesCC/DurationCC 等非物品对象）。
+      自检同时断言目录非空，并打印名称样本（如 `史诗幸运礼盒`、`紧凑型油箱`）验证字段映射。
+    - 下一步：用户拥有的物品列表来自 GarageCC 的引用字段（`itemsOnDepot` / `itemsOnMarket` /
+      `mountedItems`）与模型命令流；等这部分抓包/命令解码补齐后，用目录把 id 解析成
+      `GarageItemObject` 再派发 `SetItemsOnDepot` / `SetItemsOnMarket` / `SetMountedItems`。
   - 委派表里的已知形态：`shop` / `home` / `localBattleUserState` / `partner` 是内联 IIFE，
     已按字段具名为 `(inline@<field>)` 并从函数体抓到顶层动作名（69 / 1 / 2 / 11 个）；
     `launchParams` 是纯透传（`(pass-through)`，无 reducer），已把字段收口为 `Map<String, String>`。

+// ItemCatalog.kt —— 车库 / 商店物品目录（Pt 容器 → GarageItemObject / GarageDeviceObject）
+//
+// 为什么单列一个「目录」而不是 Redux 切片：
+//   · 抓包里最大的 Pt 容器是**静态物品表**（1371 个物品对象 + 515 个装置对象），
+//     不是用户拥有的物品列表；原包也不把它放状态层，而是由服务按需读取。
+//   · 原包的「CC → GarageItemObject」转换在 module_18334 的 `S$`（物品）与 `gct`（装置）里，
+//     逐个从对象上下文取子模型：`Gr(n, Z(token))`。token → 模型类的对应关系见下表的注释。
+//
+// 容器形态（names/model_registry.json + 抓包实测）：
+//   Pt.Items = [0(对象标记，value 是 ObjectId), 模型1, 模型2, …, 0(下一个对象), …]
+//   每个对象组里模型顺序不固定，按 modelId 建索引即可；组边界 = Id == 0 的项。
+//   物品组的模型集合（实测）：
+//     CountableItemCC, ItemPropertiesCC, ItemSaleByKitCC, BuyableCC,
+//     TimePeriodModelCC, ItemModelCC, ItemRarityCC, DescriptionModelCC,
+//     ItemCategoryCC, PremiumItemCC, ItemViewCategoryCC, DescriptionMediaCC, VisibleCC
+//   装置组在前述集合上换成 DevicePropertiesCC + TemporaryItemCC。
+//
+// 字段对应（module_18334 的 `S$`，new GarageItemObject(...) 的实参顺序）：

+//   isPremium←PremiumItemCC.PremiumItem | itemCategory←ItemCategoryCC.Category
