- **Session** (session.ts): lazily built, resident — once created it keeps eating frames in the background, so switching away and back renders instantly. Operations: `prompt`/`cancel` (RPC passthrough; failures land in the snapshot's `promptError`), `open` (pull the tail history page, idempotent), `loadOlder` (upward paging, reentry-guarded), `resync` (reconnect = clear the window and rerun open). Subscription: `subscribe`/`getSnapshot` (always the cached reference) — `implements ObservableSnapshot<ConversationSnapshot>`, with `useSelector = bindSnapshotSelector(this)` attached at construction, so a Session is directly a uSES source. Frame dispatch is one switch: `session/event` frames dedup by seq (the only dedup key), buffer while open is in flight, otherwise append + incremental fold; open/stitch merges the live buffer by seq and backfills once if `subscribed.lastSeq` outruns the window tail.
- **ConversationSnapshot** (conversation.ts): the immutable snapshot contract — `nodes` (folded, surface-ordered), `partial`, `runningCalls`, `pending`, `running`, `removed`, `openState`, `hasMore`, `promptError` and kin. **Reference discipline** (the premise of memo and uSES): the top-level object is fresh on every change; the nodes array is rebuilt but element references come from the cache; unchanged substructures reuse the previous snapshot's references.

- **ConversationSnapshot** (conversation.ts): the immutable snapshot contract — `nodes` (the human transcript, log-ordered), `partial`, `runningCalls`, `pending`, `running`, `removed`, `openState`, `hasMore`, `promptError` and kin. **Reference discipline** (the premise of memo and uSES): the top-level object is fresh on every change; an unchanged nodes projection keeps the same array reference, while a changed flow returns a new array that reuses unchanged element references; unchanged substructures reuse the previous snapshot's references.
- **SessionManager** (manager.ts): instance cluster + frame entry + the session list. sessionId-bearing frames go only to existing instances (a mux broadcast must not instantiate every session); approval/question `requested` frames are the exception — they never land in history, so they buffer in `pendingBuffers` and replay on instantiation.
- **Notifier** (notifier.ts): two channels chosen by change source. `markDirty()` (default; frame-driven changes always) batches per microtask — N changes, one notification, one re-render; the flush rebuilds the snapshot cache before notifying. `notifyNow()` (only direct echoes of user gestures) rebuilds and notifies in the same tick — controlled inputs roll the DOM back and jump the caret if their echo defers to a microtask. Frame-driven code using notifyNow collapses batching back to per-frame renders; banned.
- **FoldAdapter / PartialAccumulator**: the fold reuses the core SurfaceManager (`@deepseek-ai/dsh-session/surface`), padding sentinel events so a paged window starting at seq > 0 satisfies the core's `seq === index` assertion; a cross-window replace degrades to a tolerant linear scan and sets `foldDegraded`. Chunks stay out of the fold entirely (O(1) skip): the accumulator folds StreamChunks into `AssistantBlock[]`, a delta swapping only that block's reference, and the finalizing message discards the accumulator in the same batch (no flicker on promotion). Cost model: one chunk = one string concatenation + a dirty mark; an unsubscribed Session under a frame storm costs only the mark.
- **TranscriptAdapter / PartialAccumulator**: the transcript is the append-origin surface projected in log order (`isAppendSurfaceEvent` from `@deepseek-ai/dsh-session/surface`) plus one marker per landed compaction checkpoint — never the model surface, which shadows replaced ranges and would erase conversation the reader already saw. Node order is seq-monotonic by construction, so there is no core `seq === index` assertion to satisfy and no degradation branch. Chunks contribute no node (O(1) skip): the accumulator folds StreamChunks into `AssistantBlock[]`, a delta swapping only that block's reference, and the finalizing message discards the accumulator in the same batch (no flicker on promotion). Cost model: one chunk = one string concatenation + a dirty mark; an unsubscribed Session under a frame storm costs only the mark.
- **ConnectionController** (in `packages/client/connection`): opens the mux/host streams, pumps with for-await, reconnects with exponential backoff (500ms doubling to 10s, jitter, unlimited) behind a generation fence; sinks are injected one-way (the Controller does not know Session). Reconnect = rebuild: `onConnected` → list refresh + per-open-session resync. The object layer faces only `IApiClient`; the Web carriage (HTTP POST for the two client→server quadrants, SSE for the two server→client) and the client class family are the layering RFC's territory.

- **SessionManager**(manager.ts):实例簇 + 帧总入口 + 会话列表。带 sessionId 的帧只投已存在实例(mux 广播不得把每个会话都实例化);例外是审批/问答 `requested` 帧——它们不落 history、open 无法回补,故缓冲进 `pendingBuffers`,实例化时回放。
- **Notifier**(notifier.ts):两条通知通道,按变更来源取用。`markDirty()`(默认;帧驱动一律用它)按微任务合批——N 次变更、一次通知、一次重渲染;flush 先重建快照缓存再通知。`notifyNow()`(仅用户手势的直接回响)同 tick 重建并通知——受控输入的回响若延到微任务,DOM 会回滚、光标跳尾。帧驱动代码用 notifyNow 会让合批塌回逐帧渲染;禁。
- **FoldAdapter / PartialAccumulator**:fold 复用核心 SurfaceManager(`@deepseek-ai/dsh-session/surface`),垫哨兵事件使 seq > 0 起头的分页窗口满足核心的 `seq === index` 断言;跨窗口 replace 时降级为容错线性扫描并置 `foldDegraded`。分片完全不进 fold(O(1) 跳过):累积器把 StreamChunk 折叠成 `AssistantBlock[]`,一次增量只换该块引用;定稿消息到达即在同一批内弃掉累积器(提升无闪烁)。成本模型:一个分片 = 一次字符串拼接 + 一个脏标记;帧风暴下未订阅的 Session 只花那个标记。
- **TranscriptAdapter / PartialAccumulator**:对话记录是按日志顺序投影的 append 来源 surface(`@deepseek-ai/dsh-session/surface` 的 `isAppendSurfaceEvent`),外加每次落地的压缩检查点一个标记——绝不用模型 surface,后者遮蔽被替换的范围,会抹掉读者已经看过的对话。节点顺序天然按 seq 单调,因此既无核心 `seq === index` 断言需要满足,也没有降级分支。分片不贡献任何节点(O(1) 跳过):累积器把 StreamChunk 折叠成 `AssistantBlock[]`,一次增量只换该块引用;定稿消息到达即在同一批内弃掉累积器(提升无闪烁)。成本模型:一个分片 = 一次字符串拼接 + 一个脏标记;帧风暴下未订阅的 Session 只花那个标记。
