 ## 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 old `require(...).default(...)` call is restored, while the
-current callable export remains callable. This does not recreate the old namespace
-object's reflection shape. The `id`/`$container` aliases, eager
-published initialization and contradictory public return types are not yet reconciled.
-See [the explicit decision](../../refactor/vast-compatibility-decision.md).
+Calling `artplayerPluginVast(callback)` preserves npm1.0.0 behavior: the SDK and
+container exist before the callback, including when no callback was supplied.
+`imaPlayer`, `id` and `$container` are writable/enumerable/configurable data fields.
+SDK settings retain their own defaults. The wrapper forwards each explicit request
+and leaves ad visibility to the SDK, without adding workspace event listeners.

-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.
+Passing `{ compatibility: 'workspace-1.2' }` as the second argument retains unpublished
+workspace behavior: no player/container until `init`, `playUrl` or `playRes`; callers
+can mutate the original settings/options before initialization. Preloading and restore
+custom playback state default to true. Four ad events control the black overlay and
+active-ad suppression. Resource getters track the current session and become null
+on release. The mode is captured once; an unknown value throws TypeError before loading.
+
+Default data fields retain their last allocated values after destroy, as published
+snapshots; `container` is a live getter and becomes null. Explicit recreation updates
+the data fields to the new session. Public writes to these snapshots do not transfer
+resource ownership. Never use a retained disposed SDK as an active session.
+
+Both modes retain void request methods, async registration and SDK/callback rejection.
+The old `require(...).default(...)` call and current callable export remain available;
+this does not recreate the old namespace object's reflection shape. Contradictory
+public return declarations and the new second-argument declaration remain task04.
+See [the accepted decision](../../refactor/vast-compatibility-decision.md).
+
+Overlay IDs use the historical `art-` default prefix or `art-vast-` workspace prefix,
+with a monotonic suffix to fix same-millisecond collisions. Default styles do not add
+workspace's black background or pointer-events rule. Container identity/ownership,
+initial display:none and existing position/inset/size/z-index are preserved.

 VAST plugin for ArtPlayer

+## Initialization compatibility
+
+Existing npm calls keep creating the SDK player before the callback:
+
+```js
+artplayerPluginVast(({ imaPlayer, playUrl }) => {
+  imaPlayer.addEventListener('AdStarted', onAdStarted)
+  playButton.onclick = () => playUrl(adTagUrl)
+})
+```
+
+Code using the unpublished workspace 1.2 lazy initialization must select it explicitly:
+
+```js
+artplayerPluginVast((context) => {
+  context.playerOptions.autoResize = false
+  playButton.onclick = () => context.playUrl(adTagUrl)
+}, { compatibility: 'workspace-1.2' })
+```
+
+The callback may be asynchronous. Core destruction releases the ad session and prevents
+later requests or recreation. Explicit plugin `destroy()` allows a new ad session while
+the core is alive. See the architecture guide for mode-specific fields and defaults.
+Public TypeScript declarations for the second argument are still being reconciled in
+PKG-VAST-04; these are JavaScript usage examples, not completed declaration acceptance.

+# PKG-VAST-03：按已确认决策完成运行时兼容与资源整理
+
+基线314a1c3163e4c5bc8d1a9f1432726824ea3af7dc；本记录完成早期
+[03检查点](2026-09-12-PKG-VAST-03-lifecycle.md)的剩余初始化兼容任务。
+2026-09-14用户明确接受“保留 npm 默认行为，显式选择工作区惰性模式”，
+[具体决策与迁移示例](../vast-compatibility-decision.md)现在是实现依据。
+
+## 实现及兼容边界
+
+五个TS模块已分离工厂/异步注册、SDK边界、会话资源、DOM样式和内部类型。
+默认工厂在callback前创建Player，恢复实际npm1.0.0的id/$container/imaPlayer
+可写数据属性与SDK默认设置。默认包装层不添加工作区四事件显隐或活动请求抑制，
+透明容器保留发布样式，显式请求继续逐次转发；没有把SDK行为复制到包装层。
+
+可选第二参数`{ compatibility: 'workspace-1.2' }`保留未发布工作区的惰性初始化、
+设置/选项原对象、两个默认flags、黑色overlay、四事件显隐、活动广告抑制和资源
+实时getter。模式在工厂创建时快照一次，未知值在加载SDK前抛TypeError。
+普通已发布JS调用无需变化；依赖未发布默认惰性的代码必须按已批准方案增加选项。
+
+两种模式共享早期修复的core销毁终止、晚到SDK/回调取消、失败回滚、会话身份隔离、
+重复清理与显式重建。默认发布数据字段保留已释放资源快照，扩展container getter归零；
+后续显式重建更新数据字段，core销毁禁止重建。工作区资源getter随当前会话归零。
+ID保留各自art-/art-vast-前缀并增加递增后缀，保留已复现同毫秒碰撞的修复。
+
+公开声明没有在本任务完成：04仍须协调历史同步误声明、回调字段、第二参数和准确
+类型入口；本次运行时授权不自动授权其他类型取舍。实际Google IMA由05验收，最终
+安装分发由06验收。README明确JS示例及当前声明门槛；未改变包版本或依赖/lockfile。
+现有docs/assets/example/vast.js使用默认回调和playUrl，符合npm模式，不需改写。
+
+## 验证与失败记录
+
+完整输入/日志/产物指纹见[验证索引](../baselines/vast-compatibility-validation.json)。
+
+- 新兼容文件初始7项：旧候选2通过5失败，包含默认初始化、旧字段与提前构造失败。
+  修复后7通过，再补回调失败的二次清理异常、显式重建和选项快照/非法值，最终10通过。
+- 当前完整`yarn test:vast`82通过、零跳过；包括旧发布/冻结工作区观察、显式模式及默认
+  生命周期。该文件进入test:vast/test:unit；工程脚本相关12项测试通过。
+- 三桌面引擎×三个核心×四种实现/模式162通过：99候选、63历史。核验异步注册门控、
+  回调开始前资源、字段描述符、默认值、真实DOM显隐/清理、主片解码及切源。
+  候选两模式执行同一份编译源码，以选项区分；第三方SDK为明确标记的受控记录器。
+  本次报告确认核心实际为npm5.1.7、npm5.4.0、候选5.4.1；早期文档将published路径
+  写成5.4.1不准确，以附件中的来源哈希和实际coreVersion为准，本次更正维护说明。
+- 首轮153通过9失败：旧candidate显隐用例沿用工作区art-vast-选择器与四事件显隐，
+  和已确认的npm默认语义不符。保留原日志/trace；按两种历史行为验证实际容器数、
+  0/4监听、显隐，再验证重建/销毁。回调失败也按实际容器前缀检测，避免虚假零残留。
+  增加回调开始时字段/时机断言后162通过；源码lint整理后最终162再次通过。
+- 严格TS5.9.3及源/测试lint通过。初次lint6项格式/声明顺序错误已修正并保留日志；
+  没有引入禁用规则。严格固定工具链检查通过。
+- 正常VAST构建三格式成功，dist与docs/compiled对应文件哈希一致。实际main+ESM和
+  legacy+ESM分别4项导出用例通过：CommonJS/global/AMD和原生ESM，均验证default别名。
+  这些产物用例使用已销毁宿主，不执行IMA；不能把它们解释为正式SDK广告播放通过。
+
+## 任务边界及回退
+
+PKG-VAST-03完成运行时结构/资源/初始化协调，VAST-CONTEXT-01按用户决策接受限定范围。
+VAST-LIFE-01保留实际供应商恢复验证门槛；VAST-TYPE/DIST及04/05/06仍开放。
+没有使用VPN例外、模拟广告成功、远端CI或npm发布声明。
+
+本任务独立本地commit包含源、测试、构建、文档、任务及风险索引，提交后核验审计。
+回退本提交并重建VAST会恢复此前默认工作区初始化，也撤销本次兼容选择；旧已发布
+默认调用的失败将重现。早期资源修复检查点不随本提交回退而消失。

+
+用户于2026-09-14明确接受npm提前初始化默认、显式workspace-1.2惰性模式。

+显式模式保留工作区四事件显隐、活动请求抑制、可变设置和资源实时getter。
+两者共享销毁终止、失败回滚、旧会话隔离和显式重建修复；模块地图/迁移JS示例同步。
+
+当前Node82通过，三浏览器162通过（99候选、63历史），工程脚本12通过；严格
