…析包身份字段 - BuildManifest 解析 name / publicKey / version / createdAt / engine / protocol / hashes / runtimeVersion， 缺 name 或 publicKey 即解析失败 - Bundle.load(files).page(name)：运行时字节码读一次共享，.js.map 读到就交给 SourceMaps，读不到用 EMPTY； SourceMaps 加 isEmpty - sample 资源目录改为每包一个子目录 files/tinyui/sample/，App 与 Android host 冒烟测试改走 Bundle Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Reviewer's GuideImplements M2 package consumption in core: manifests now expose and validate package identity metadata, Bundle provides cached runtime/page/source-map loading over an abstract file reader, and the sample plus Android smoke test use the new API with package-isolated resources.

- page = PageModule("sample/todos", Res.readBytes("files/tinyui/${manifest.file("sample/todos")}.bin"), manifest.buildId("sample/todos")),
- maps = SourceMaps(maps),
- )
+ val bundle = Bundle.load { path -> runCatching { Res.readBytes("files/tinyui/sample/$path") }.getOrNull() }
+ val loaded = bundle.page("sample/todos")
+ // debug builds ship the maps (-Ptinyui.maps); stacks on the failure screen only when they came along
</code_context>
<issue_to_address>
**issue (bug_risk):** `runCatching` catches `CancellationException` from `Res.readBytes`, converts coroutine cancellation into a null byte result, and then `Bundle.load` reports a misleading missing-manifest or missing-file error instead of propagating cancellation.
**Triggers:** When the `LaunchedEffect` is cancelled while a package resource is being read, such as when the composable leaves the composition or the host scope is cancelled.
**Suggested fix:** Catch ordinary resource-read failures without swallowing `CancellationException`, or rethrow `CancellationException` from the `runCatching` block.

In `@compose/src/commonMain/kotlin/app/tinyui/BuildManifest.kt`:
- Around line 36-39: Update the JSON value extraction in BuildManifest so null
primitives are treated as absent: use contentOrNull instead of content for the
local string helper and the runtimeVersion mapping. Preserve the existing
empty-string defaults for required identity fields name and publicKey, while
allowing a null runtimeVersion to remain Kotlin null.

结论：批准
摘要
本次改动新增了 BundleFiles、Bundle 和 LoadedPage，并将 sample 与 Android host 测试接入新的包加载流程。BuildManifest 也扩展了解析的包身份和构建元数据字段，运行时字节码与缺失 source map 的缓存逻辑在给出的代码中处理一致。未发现可依据现有代码确认的缺陷。
