		# @hy-bricks/canvas

		## [0.6.2] - 2026-06-23 · 隐藏实例保活(修隐藏→恢复丢状态)

		非破坏 patch。@hy-bricks 4 包同步升 0.6.2。

		### Fixed
		- 隐藏(`hidden`)实例再恢复显示时不再丢组件内部状态:root 实例 `hidden=true`(`v-show` → `display:none`)会被 RenderScheduler 的 IntersectionObserver 判为"离开视口",超 `disposeDelayMs`(默认 1500ms)就 dispose 卸 vm → 恢复时重挂全新组件、用户选值 / 查询条件 / 取数结果复位(常见症状:恢复后取数裸跑、缺参报错)。修:`hidden` 的 root 实例自动 `RenderScheduler.setHeld` 保活,豁免视口外 dispose,恢复无缝(同一个 vm)。容器子走 Teleport 不经 scheduler,本就不受影响。
		- Teleport outlet `isConnected` 守卫:父实例卸载瞬间 outlet DOM 已脱离文档但 ref 残留,`resolveOutlet` 加 `isConnected` 判断 → detached 返 null,不往已移除节点投(消除父卸载瞬间子 Teleport 竞态)。

		### Added
		- `RenderScheduler.setHeld(id, held)`:标记实例保活,豁免视口外 dispose(供渲染器实现 hidden 保活)。
		- `HyperCardPageRenderer` 新 prop `keepHiddenMounted`(`boolean`,默认 `true`):隐藏实例保活开关;传 `false` 退回老行为(隐藏可被 dispose,省内存但恢复丢状态)。
		- spec:`createRenderScheduler.spec.ts` +4(setHeld);canvas test → 1717。

		> 已知小尾(记 `docs/feedback/portal-ui/`,后续增强):保活后隐藏实例的数据绑定 / 订阅仍在跑(给不可见组件推更新);要"隐藏暂停取数"需配套"显示时 invalidate 补数",否则恢复显旧值。
