+# VAST implementation and maintenance
+
+This is the PKG-VAST-03 implementation checkpoint. The published-versus-workspace
+initialization conflict remains open; this checkpoint is not release acceptance.
+
+## Module map
+
+- `src/index.ts` owns the core destroy subscription before SDK loading begins,
+  awaits SDK loading and the user callback, and preserves original rejection values.
+- `src/sdk.ts` is the only runtime Glomex import boundary. It also constructs IMA
+  requests, preserving own/inherited configuration fields and primary-field overrides.
+- `src/session.ts` owns one current SDK/container pair, the four ad-event subscriptions,
+  active-ad request suppression, initialization rollback and explicit recreation.
+- `src/view.ts` creates the existing overlay styles and distinct per-module container
+  IDs, including multiple instances initialized in the same millisecond.
+- `src/types.ts` describes the implementation context and SDK boundary. Public legacy
+  declarations in `types/` remain separate pending PKG-VAST-04 reconciliation.
+
+Dependency direction is entry -> session -> SDK/view/types. The session passes the
+original `art` through the callback for compatibility; only template elements are
+used for SDK allocation. Constructor utility access is narrowed once at the entry.
+
+## Lifetime and errors
+
+The entry subscribes before awaiting the shared SDK loader. Core destruction makes
+that attachment terminal, removes the subscription and releases the current session.
+It does not cancel the shared IMA script load for other instances. A late completion
+does not invoke the callback or allocate a player. SDK failures still reject with
+their original value. Callback failure closes the attachment and releases resources;
+secondary cleanup failures are logged without replacing the original error.
+
+Explicit plugin `destroy()` releases the current ad session, resets active-ad state,
+and permits a later `init`/`playUrl`/`playRes` while the core remains alive. Core destroy
+and failed attachment are terminal: request methods are inert and `init()` returns
+null. Public declaration accuracy for this invalid-lifetime case belongs to04.
+
+Each session has an owner identity. Its callbacks verify that identity and core
+liveness before changing visibility. Cleanup detaches the current owner and clears
+references before invoking SDK code, removes each subscription, destroys the SDK and
+removes the container even when another cleanup operation throws. A cleanup exception
+is observable, but cannot leave the wrapper pointing at a half-destroyed player.
+
+Initialization is guarded against reentrancy. Constructor/subscription failure rolls
+back; destruction reentered during constructor completion releases the late player.
+Config accessors can execute user code, so request dispatch verifies owner identity
+again after request construction. Cleanup itself prevents reentrant recreation until
+it finishes. SDK content pause/resume behavior is not duplicated in this wrapper.
+
+## Compatibility and remaining work
+
+The checkpoint retains the workspace callback order, lazy initialization, mutable
+settings/options identities, default flags, void request methods, and asynchronous
+outer attachment. The historical namespace export, `id`/`$container` aliases, eager
+published initialization and contradictory public return types are not yet reconciled.
+See [the explicit decision](../../refactor/vast-compatibility-decision.md).
+
+The former timestamp-only overlay ID now has a monotonic suffix to avoid same-tick
+collisions; the existing `art-vast-` prefix and CSS styles remain. IDs are internal
+in the workspace context; published ID compatibility is tracked with the above decision.
+
+`@alugha/ima@2.1.0` is a direct pinned dependency because Glomex declarations import its
+types while Glomex lists it only as a development dependency. Runtime imports continue
+to use Glomex1.21.2. No new direct remote loader or SDK major upgrade was introduced.
+
+## Validation
+
+Run `yarn test:vast`, `yarn typecheck`, `yarn build artplayer-plugin-vast`, and
+`yarn test:browser vast.spec.js` using the repository pinned toolchain. The node and
+browser wrapper tests substitute only the Glomex SDK boundary. They cover current and
+frozen historical sources, real core5.1.7/5.4.1/candidate registration, real DOM and
+main-video decoding; they do not certify Google IMA ads or final npm distribution.
+
+For state or cleanup changes start in session, for callback timing in entry, and for
+SDK request fields in sdk. Keep Node candidate assertions, historical observations,
+browser counterparts and [test maintenance](../../refactor/vast-validation.md) aligned.
+Actual IMA/media/device validation remains05, public types04, and full distribution06.

+起点d5e1fead。原index.js迁为5个严格TS模块：入口、SDK/request边界、session所有权、
+DOM视图及内部类型。实际职责/依赖/时序见
+[包内架构](../../packages/artplayer-plugin-vast/ARCHITECTURE.md)。
+
+核心destroy在SDK加载前订阅；加载或callback完成后不会再创建终止实例的广告。
+session销毁时先使旧owner失效，再逐项释放监听/SDK/DOM，异常不阻断剩余清理；
+构造和事件注册失败回滚；旧事件不能污染新session；活动广告显式destroy后可重建。
+构造/订阅/销毁重入及request配置getter引发销毁/替换也有身份检查。
+
+15项候选生命周期断言配合45项已有行为/历史观察，60项Node通过；另在冻结工作区
+执行同一候选断言记录修复前失败。三格式正式构建成功，117项真实浏览器测试通过，
+包含三核心/三引擎的新增终止、回调失败、旧事件与显式重建路径。SDK边界仍受控，
+不代表正式bundle中的实际IMA执行；该部分留给05/06。
+
+直接固定依赖@alugha/ima2.1.0（MIT），补齐Glomex声明引用但未作为运行依赖提供的
+类型链；保持Glomex1.21.2与其实际SDK加载器，新增依赖没有直接运行时import。
+Yarn仅新增该依赖和相应锁条目；包的tsconfig纳入严格检查，未用skipLibCheck掩盖错误。
+初次lint发现单行try格式不符后修正，没有通过忽略整个文件避开检查。
+
+**本任务仍doing**：[初始化决策](../vast-compatibility-decision.md) 展示npm发布版
+eager与未发布工作区lazy的不可同时满足条件。当前默认行为暂保持工作区，尚未恢复
+发布id/$container，因此不能声称03兼容验收完成。拟定方案默认保持npm1.0.0行为、
+另提供显式工作区兼容选择；尚未实现，等待用户确认。Ads批准不扩展到VAST。
+
+公开类型同步误声明、历史CJS.default入口仍由04处理。新ID增加同毫秒区分后缀，保留
+workspace art-vast-前缀；发布ID规则与上面的初始化决策一起处理。SDK-07及VAST相关
+风险继续open，候选可控修复证据与实际供应商/发布验收分开记录。
+
+执行结果、输入和产物指纹见 [验证记录](../baselines/vast-lifecycle-validation.json)。
+本批作为03未完成检查点独立本地提交；不push/tag/publish。回退该提交恢复旧VAST
+源码、依赖、构建输出和测试接入；01/02不可变基线与历史缺陷证据保留。
+
+最终完整本地CI900项通过（832单元、14工程、54基线），274个生产TS检查，37份核心
+声明无漂移；15个候选断言在旧工作区均失败，修复后全部通过。TS5.9.3/4.3.5当前
+最小公开消费者的缺失类型错误均消除，但同步返回误声明仍开放。

+# VAST 初始化兼容决策：待用户选择
+
+来源：[真实发布契约](baselines/vast-contract.md)；已可重跑的
+`vast-contract.test.mjs`及`test/vast.test.js`固定以下矛盾：
+
+| 同一次 callback 开始时 | npm1.0.0 | 未发布工作区1.2.0 |
+| --- | --- | --- |
+| imaPlayer | 已构造、非null | null，直到init/playUrl/playRes |
+| DOM | 已挂载$container，并提供id | 不存在容器，container getter为null |
+| 设置 | IMA默认值 | 默认启用preloading及restoreCustomPlaybackStateOnAdBreakComplete |
+
+实际发布用户可以直接写 `({ imaPlayer }) => imaPlayer.addEventListener(...)`。
+工作区用户可以先判断`context.imaPlayer === null`并修改`playerOptions`，然后等待
+用户操作调用`init()`。在同一默认调用中无法同时保留非null和null，以及相反初始化时机。
+添加别名或getter也无法同时满足两种值；按callback源码猜测用户版本不可取。
+
+## 推荐的具体处置（尚未实现）
+
+优先保持实际npm1.0.0默认行为：回调前初始化、提供id/$container，SDK默认设置保持
+发布语义；保留workspace新增的init/container/settings等字段作为扩展。
+
+确实依赖未发布1.2.0惰性行为的代码，拟通过新的可选第二参数明确选择该兼容模式：
+
+```js
+// npm旧用法保持原样
+artplayerPluginVast(({ imaPlayer, $container, id }) => {
+  imaPlayer.addEventListener('AdStarted', onAdStarted)
+})
+
+// 未发布工作区1.2.0的初始化时机与默认设置保留在显式模式
+artplayerPluginVast((context) => {
+  context.playerOptions.autoResize = false
+  button.onclick = () => context.playUrl(adTag)
+}, { compatibility: 'workspace-1.2' })
+```
+
+这意味着依赖未发布1.2.0默认惰性的代码需要增加一个参数。普通npm1.0.0用户保持
+原调用；这不是声称两种相反语义完全兼容。第二参数仅为待确认方案，当前生产代码
+尚未新增它；类型误声明、CJS.default和分发路径仍各自单独验证。
+
+## 当前检查点
+
+生命周期与资源修复不依赖该选择，已经推进；默认初始化暂保持工作区行为，不把
+PKG-VAST-03或VAST-CONTEXT-01标完成。用户针对Ads的类型推导批准不适用于本决策。
+需要用户确认是否按推荐方案优先实际发布默认行为；也可指定其他取舍。
