 ### Side-effect channel, converging with window replay
 
-`applyEventSideEffects` gains a `todo/write` case (whole list, last write wins) and `rebuildDerivedFromWindow` resets it, so the live path and every window rebuild (paging, reconnect stitch, resync) converge on the same latest snapshot — the same shape partial/openCalls already use. `ConversationSnapshot.todos` is the read surface. This follows the event's own contract ("log-only UI state; never derived history"): surfacing each write as a conversation node would render superseded lists as if they were still standing.
+`applyEventSideEffects` gains a `todo/write` case (whole list, last write wins). Unlike partial/openCalls, `rebuildDerivedFromWindow` deliberately does NOT reset it: the value is session-level — seeded by the tail history page's full-log projection — and an arbitrary window may not contain the latest write, so rebuilds (paging, reconnect stitch, resync) preserve it and only an in-window or live write overwrites it. `ConversationSnapshot.todos` is the read surface. This follows the event's own contract ("log-only UI state; never derived history"): surfacing each write as a conversation node would render superseded lists as if they were still standing.
 
 ### TodoPanel: the durable list as a persistent strip
 
 The skeleton pins the panel between the view area and the composer (the composer-card axis), hidden while empty, collapsible with the in-progress item as the collapsed one-line hint; ✓/●/○ glyphs mirror the TUI plan panel. It reads `snapshot.todos` via the framework `useSession` hook — no store, no service, no ctx. It lives inside `ConversationRoot` rather than the details column or its own slot: the details slot is single-occupant and selection-driven (a different lifetime than an always-on strip), and the slot table reserves no plan seat. The component is props-complete and framework-free, so a later relocation to a dedicated slot touches nothing inside it.

 ### 副作用通道，与窗口回放收敛
 
-`applyEventSideEffects` 新增一个 `todo/write` 分支（整份列表，后写覆盖先写），`rebuildDerivedFromWindow` 将其重置，于是实时路径与每一次窗口重建（分页、重连缝合、resync）都收敛到同一份最新快照——partial/openCalls 已在用的正是这个形态。`ConversationSnapshot.todos` 是读取面。这遵循事件自身的契约（「仅日志 UI 状态，绝非派生历史」）：把每次写入作为对话节点呈现，会让已被取代的列表看起来仍然有效。

 ### TodoPanel：长驻列表作为一条常驻横条
 
 骨架把面板钉在视图区与 composer 之间（composer-card 轴），空列表时隐藏，可折叠——折叠态以进行中项作为单行提示；✓/●/○ 字形与 TUI plan 面板一致。它经框架 `useSession` hook 读取 `snapshot.todos`——无 store、无 service、无 ctx。它住在 `ConversationRoot` 之内，而非 details 列或自建 slot：details slot 单占用且由选中驱动（生命周期不同于一条常开横条），且 slot 表没有为 plan 预留席位。组件 props 完备且框架无关，因此日后迁往专用 slot 不触及其内部任何东西。
