M6 第 8 点的前一半（docs/updates.md §1.3）：发布前核对目标宿主版本
需要知道包用到了什么。分析的是 esbuild 打出的每页产物而不是源码——
本地 import 已合并、未用代码已摇掉，一页一份，不必追 import 链。
- 能力：按 import 找到 tinyui-native 的 host 的本地名，只认
host.call("…") 的字面量名字；动态名字、把 host 或 h 赋出去都拒绝，
否则会有看不见的调用
- 宿主组件：h() 的类型为字面量、core 的导入、本地组件函数、生成的
常量对象成员，或这些之间的条件选择；其余（经变量别名、参数、运行时
计算）都拒绝。只记带点的名字，内置组件随 tinyui 版本走
- 一次构建报出所有违规，按 esbuild 的模块横幅标出源文件
夹具 app 的页面补上 Column / Text 的 import：它只做过纯 JS 编译，
未声明的组件标识符按新规则会被拒绝。TrendingAI 订阅页实测找出
5 个能力、2 个宿主组件，无违规。

摘要
该 PR 在页面 ESM 打包完成后解析 AST，收集 host.call 能力和 h() 使用的宿主组件，并将结果写入 manifest 的 requires。整体流程会汇总所有页面的分析错误后再失败。主要风险是组件对象成员被当作初始化时的固定字面量，但对象属性在运行时可被修改，从而可能漏记实际使用的组件；此外能力名未遵守仅记录带点名称的约定。

+ walk(program as unknown as AnyNode, null, (node, parent) => {
+ if (node.type !== "Identifier" || !isReference(node, parent)) return;
+ const name = node["name"] as string;

</code_context>
<issue_to_address>
**issue (bug_risk):** Binding resolution is global rather than lexical: a local parameter or declaration named `host` or `h` anywhere in the bundled page makes `only(bindings.get(name))` return undefined for every occurrence of that name. The analyzer then silently skips the real imported `host.call(...)` or `h(...)` usage, so the manifest omits required capabilities or components instead of rejecting the page.
**Triggers:** When a page contains an imported `host` or `h` and an unrelated nested scope declares the same identifier.
**Suggested fix:** Resolve identifiers against their lexical scopes, or conservatively report an ambiguity for the affected reference instead of dropping it.
```suggestion
const candidates = bindings.get(name);
if (candidates && candidates.length > 1) {
problem(node, "cannot resolve this identifier because it has multiple bindings");
return;
}
const binding = candidates?.[0];
```
</issue_to_address>Sourcery assessment
Needs a human reviewer. 1 finding to address first, and a wrong analysis can persist incorrect host requirements in built manifests, allowing a package to target an incompatible host and fail at runtime. Reverting stops future bad builds, and affected manifests or packages can be regenerated and republished, so the impact is bounded and repairable.

- Around line 41-56: Update the binding checks in the analyzer around `binding`
and `componentTypes` to reject default and namespace imports from
`tinyui-native`, and reject `tinyui-core` default or namespace uses except
non-computed member access to a property other than `h`. Preserve the existing
named-import handling for `host` and `h`, including capability recording and
component resolution.
- Around line 39-41: In the name-resolution logic within analyzePage, detect
when bindings for a referenced name are ambiguous because multiple declarations
include a core or native binding. Return a problem for that node asking the
caller to rename the local, rather than letting only() return undefined and
silently omitting the requirement; keep the existing unique-binding handling
unchanged.

审查指出： - 按名字而非作用域解析，页面里另有一个叫 host / h 的参数或局部变量 时，真正的导入会被跳过、所需能力不进 manifest。改为重名即报错；顺带 修正函数参数本身是标识符时根本没被登记为声明 - import * as native 之后 native.host.call(…) 两项检查都被绕过。命名 空间导入改为只允许按成员使用，并沿 native.host / core.h 继续核对 - 组件对象的成员按初始值解析，但对象之后若被改写、删属性、调方法或 整个传出去，渲染时可能已是别的值。只有全部用法都是 obj.key 读取的 对象才解析 build-chain.md §5.1 同步补上这三条限制。 Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

摘要
本次增量增加了 namespace import 的跟踪、同名声明的拒绝，以及对生成组件对象被直接修改的防护。能力名仍会原样写入 manifest，未满足只记录带点名称的既定规则。组件对象的修改检测只覆盖直接以成员表达式为左值的情况，仍可通过解构赋值等语法绕过并产生错误的组件依赖清单。

M6 拍板第 8 点的前一半（
docs/updates.md§1.3、docs/build-chain.md§5.1）。发布前要核对"这个包用到的宿主东西，目标宿主版本都提供"，这个 PR 负责"包用到了什么"：tinyui build把它写进 manifest 的requires。bundle从热下发服务读快照做比对，是后续的 PR（依赖服务端的快照端点）。为什么分析打包产物而不是源码
esbuild 为每页打出一份自包含的 ESM：本地 import（比如
src/host/index.ts里对host.call的封装）已经合并，没用到的代码已经摇掉。分析它就是分析这一页真正会上设备的内容，不必自己追 import 链，结果天然按页。用 CLI 已有的oxc-parser，不加依赖。规则

bundle核对版本相等。宁可多报：一个用到的函数里 if / else 两边都算，取不到的分支也算。一次构建报出所有页面的所有违规，按 esbuild 打在每个合并模块前的
