摘要
本次改动建立了 schema 生成链，并接入了内置组件、HostServices 和 native API。主要风险集中在运行时契约未完整落实，以及 HostServices 的订阅和并发状态处理：必填 prop、订阅去重和并发写入的可见顺序目前都有缺口。另有 K1 挂载路径未被新加的超时保护覆盖，页面初始化卡死时无法按约定失败退出。
其他意见
不在改动行上，无法挂为行内评论：
compose/src/commonMain/kotlin/wang/harlon/tinyui/PageHost.kt:101[严重] 5 秒超时只包在后续的entry()调用中，start()内的模块加载、mount和首次flush没有任何超时保护。页面模块或首次渲染中的同步死循环会永久占住该页引擎，既不会触发E6，也不会进入failure状态。应把初始化阶段的 K1 调用也纳入同一套超时/中断机制。

insert()does not inspectComponentSchema.children. A patch can insert a child underText,Button,Spacer, or another leaf component.The insertion succeeds, but the component never renders the child. This leaves an invisible subtree in the node model.

Inline comments:
In `@compose/src/commonMain/kotlin/wang/harlon/tinyui/components/Builtins.kt`:
- Around line 175-176: Update the snapshotFlow collection around
state.isScrollInProgress so it ignores the initial false emission, records that
scrolling has started when true is observed, and dispatches onScrollEnd only
when a subsequent false value ends that scrolling transition. Preserve the
existing index payload and distinct-value handling.
In `@compose/src/commonMain/kotlin/wang/harlon/tinyui/node/NodeTree.kt`:
- Line 78: Update the node creation logic using UiNode and
ComponentRegistry.PLACEHOLDER so unknown components retain the requested type in
the UiNode schema while still rendering through the existing placeholder
fallback. Ensure EmptyPlaceholder remains zero-size and does not apply layout
properties from the placeholder schema.
In `@compose/src/commonMain/kotlin/wang/harlon/tinyui/PageHost.kt`:
- Around line 259-261: Synchronize subscription registration and teardown in the
host lifecycle around send(), close(), and the subscriptions collection:
atomically mark the host closed before draining handles, prevent registration
from racing with iteration, and immediately close any store or event handle
registered after closure. Ensure close() drains and clears all existing handles
without leaving subscriptions active.
- Line 296: Update Scope.modifier() so the common Modifier.clickable is not
added for Material3 OutlinedButton, TextButton, or Button elements. Use a
layout-only Scope modifier for those three variants while preserving their own
onClick and enabled handling; retain the existing clickable behavior for other
elements.
In `@compose/src/commonMain/kotlin/wang/harlon/tinyui/TinyUIPage.kt`:
- Line 22: Update the TinyUIPage composable’s default services handling to
create the fallback HostServices instance with remember, then use that stable
instance as the PageHost key. Preserve the behavior for callers that provide an
explicit services value.
In `@packages/cli/src/bin.ts`:
- Line 64: Update the schema command flow around the targets collection so it
rejects invocations where both --ts and --kt are absent, returning a nonzero
status instead of reporting success. Preserve normal processing when at least
one output target is configured.
In `@packages/cli/src/schema/dsl.ts`:
- Around line 54-55: Update enumOf to require at least one value in its values
tuple, preventing empty enum definitions from producing invalid TypeScript;
preserve the existing behavior for non-empty enum values and their defaults.
- Around line 77-81: Update defineComponent validation for props, events,
commands, and fields to reject names that are not valid TypeScript identifiers,
including hyphenated names such as foo-bar; alternatively, update the
corresponding generate.ts member emission to quote non-identifier names. Apply
the same rule consistently to every generated member category while preserving
existing reserved-name and event-name checks.
In `@packages/cli/src/schema/generate.ts`:
- Line 7: The generateTs function hardcodes the Node import path, while schema()
can target different output paths. Update generateTs and its call from schema()
to derive the node module specifier relative to the configured output file, and
use the same computed specifier for both Node and Ref imports.
In `@packages/cli/src/schema/load.ts`:
- Around line 19-23: Update the duplicate validation in the component-list
loading flow to check collisions after applying both generators’ identifier
transformations, such as ktIdent and tsIdent, rather than only comparing source
c.name values. Track transformed Kotlin and TypeScript identifiers independently
and reject duplicates with an appropriate error.
In `@sample/js/src/pages/todos.tsx`:
- Line 14: Update the todos page around the initial request handling and add
form rendering so the form is unavailable until first() succeeds. Prefer placing
the add form inside the successful Show branch, or otherwise preserve locally
added todos when applying the response in the untrack callback that calls
setTodos and setNext.

Derive generated imports from the --ts output path.
schema() passes v.ts as the target but calls generateTs(components) without the output path. generateTs hardcodes ../node.ts for both Node and Ref.
This import is valid for the configured packages/core/src/generated/components.ts path because it resolves to packages/core/src/node.ts. It is invalid for other supported paths, such as packages/core/src/components.ts, where ./node.ts is required.
Compute the relative import from the output file, or pass the computed specifier to generateTs and use it for both imports.

摘要
本次增量为默认 HostServices 提供稳定实例，并对 store 通知引入版本号过滤、对事件/store 订阅按 key/topic 去重，同时修复了列表末尾重试和 Button/TextField 嵌套点击问题。NodeTree 也新增了创建 flush 结束时的必填 prop 校验。主要剩余风险是必填 prop 可以通过创建期写入 null 绕过校验，导致运行时仍以组件兜底值渲染。

[建议] UiNode 是公开类，且 NodeTree.root、NodeTree.node、NodeScope.node 和 NodeScope.RenderChild 都暴露了该类型；改名后旧符号从 ABI 中被移除，已有 Kotlin 调用方会编译失败，已编译客户端也无法链接。若需要保持兼容，应保留 UiNode 作为兼容类型/API 并逐步弃用，或者将此变更作为明确的破坏性版本升级发布。
