Reviewer's Guide本 PR 仅更新文档：新增 ADR-007，按“改动是否需要宿主发版”重新划分页面包、框架与宿主职责，并重写原生 API、热下发契约、应用模型、构建链、组件、运行时和路线图文档，为后续实现及 TrendingAI 订阅页迁移定义标准接口、兼容规则和验收边界。 Sequence diagram for a page request selecting an HTTP channelsequenceDiagram

### Comment 1
<location path="docs/updates.md" line_range="37-38" />
<code_context>
| `createdAt` | `tinyui build` | ISO 8601 UTC，新旧比较只看它 |
| `engine` | `tinyui build` | 字节码文件头里的引擎 commit（40 位 hex，所有 `.bin` 一致，取第一个）；客户端要求等于宿主 |
-| `hashes` | `tinyui build` | 模块名 → 该模块 `.bin` 的 sha256 hex，键与 `files` 一致 |
+| `hashes` | `tinyui build` | 模块名 → 该模块 `.bin` 的 sha256 hex，键与 `files` 一致；另含每个 i18n 文件，键为其相对路径（`i18n/en.json`） |
+| `i18n` | `tinyui build` | `{ "default": 默认语言, "files": { 语言: 相对路径 } }`，包没有 i18n 资源时省略（build-chain.md §8） |
| `tinyui` | `tinyui build` | JS 工程构建时的 `tinyui-core` 版本，即页面需要的最低运行时（能用哪些内置组件与运行时 API）；`publish` 核对目标宿主版本的 tinyui 下限与它兼容（§1.3），客户端核对它与 `TinyUI.version` 兼容（§4.3）。**兼容 = major 相同，且宿主的版本不低于包的**（semver `^`；0.x 之间按版本号全序比较，1.0 之前不允许破坏公开面）。成立的前提是运行时公开面只增不删（runtime-api.md §11）；升 major 时宿主加 `hostVersion`（§4.1），旧 major 的包因不兼容被拒收 |
-| `requires` | `tinyui build` | 页面模块名 → `{ components, capabilities }`：该页用到的带点宿主组件名与 `host.call` 能力名，各自排序；内置组件不列。`publish` 据此核对目标宿主版本（§1.3），客户端不读 |
</code_context>
<issue_to_address>
**issue (bug_risk):** The OTA package and delivery protocol do not include the new `i18n` files: the package layout lists only `manifest.json` and `pages/**/*.bin`, and the documented delivery endpoint only fetches `.bin` files, even though the manifest references `i18n/<locale>.json`. A hot-downloaded package therefore has a manifest pointing to resources that were never delivered or verified, so package i18n lookup fails.
**Triggers:** When a package with i18n resources is installed or updated through hot updates.
**Suggested fix:** Add i18n files to the final bundle layout and delivery protocol, including download and hash-verification rules for each manifest `i18n.files` entry.

<code_context>

+## 2. J2 白名单
+
+框架固定，业务不能加；同步返回 JSON 文本，没有就是 `null`。实现全部在框架内、只读内存：
-实现必须在调用线程立即返回、不做 IO（ADR-002 §3.1 场景 3）。
+| 名字 | 返回 |
+|---|---|
+| `device.info` | 对象：`os`、`osVersion`、`model` |
+| `store.get` | 任意（§4） |
+| `storage.get` | 任意（§7） |
+| `storage.set` | `null`，或错误码 `E_QUOTA`（§7） |
+| `i18n.t` | 字符串（§8） |
+| `i18n.locale` | 字符串（§8） |
+| `session.get` | `{ loggedIn, userId }`（§9） |
</code_context>
<issue_to_address>
**issue (bug_risk):** The J2 contract gives `storage.set` a synchronous return shape of `null` or an `E_QUOTA` error code, while the JavaScript API contract says it throws a `HostError` with `E_QUOTA`. Implementations and callers following these two sections will disagree about whether quota exhaustion is a returned value or an exception, causing quota handling to be ineffective for one side.
**Triggers:** When `storage.set` exceeds the per-package quota.
**Suggested fix:** Define one behavior consistently—prefer rejecting/throwing `HostError(E_QUOTA)`—and use that shape in the J2 table and JavaScript API description.

摘要
本次改动通过 ADR-007 将网络、存储、i18n、会话、通用 UI 与埋点门面收归框架，并同步扩展了 TinyUIHost、构建产物和热更新快照。主要风险在于部分标准宿主接口被允许缺省却未纳入兼容性约束，以及原生路由失败时的行为在文档间不一致。这些问题会让热更新包在目标宿主上出现无法预检的功能失败，或导致各端实现不一致。

- Line 187: Update §4.1 of docs/updates.md to reconcile its okio dependency
statement with the decision recorded in the ADR: acknowledge that core also
depends on okio for storage, or clarify that tinyui-updates retains separate
okio usage. Remove the claim that okio is unique to tinyui-updates and absent
from core.
