Summary Interrupted or errored turns stay recoverable: the incomplete assistant message is kept as a candidate, and /recover continues the turn append-only without rewriting history. Conversation titles can be generated through a dedicated API (POST /experimental/title, plus a genTitle helper) that falls back to a lite model when the preferred one is unavailable or returns invalid output. TUI voice input is upgraded to a tool-based voice_input protocol: ASR applies caret/selection-aware insert or set, submit stays explicit through the send field, and the call shape is validated so models can drive it reliably. Also in this release: compaction keeps a summary plus only the API rounds that arrive while that summary is generated, triggers at a flat 90% of the context window, and collapses the post-rebuild tail into an activity log; unused actor spawn/run resume arguments removed so models are pointed at send (already the supported path for waking and continuing a subagent); subagent actor use via exec limited to send; nested exec tool calls persisted and replayable in the TUI; same-session subagents inherit parent permission grants; per-session system prefix frozen in a snapshot for stable prompt-cache prefixes; optional auto_worktree notice (default off); skills updates for mate, pdf-official CJK fonts, and pptx-official image sourcing; plus provider/retry, MCP, compose-next, and build fixes.

中断或出错的回合仍可恢复：未完成的 assistant 消息会保留为候选，/recover 以 append-only 方式续跑，不改写历史。 会话标题可通过专用 API 生成（POST /experimental/title 与 genTitle helper）；首选模型不可用或返回无效结果时，会回退到 lite model。 TUI 语音输入升级为基于工具的 voice_input 协议：ASR 按光标/选区做 insert 或 set，发送始终由 send 字段显式触发；调用 schema 经过校验，模型可以稳定驱动。 本版本还包括：compaction 保留 summary 以及生成期间到达的 API 轮次，触发条件改为上下文窗口的固定 90%，重建后的 tail 收成活动日志；删除 actor spawn/run 中未实现的 resume 参数，把模型导向本来就能用的 send；子代理经 exec 使用 actor 时仅允许 send；嵌套 exec 调用会持久化且可在 TUI 回放；同会话子代理继承父级权限；会话 system prefix 冻结进快照以保持 prompt-cache 前缀稳定；可选的 auto_worktree 提示（默认关闭）；mate、pdf-official 中日文字体与 pptx-official 配图规则等 skill 更新；以及 provider/重试、MCP、compose-next 与构建相关修复。 Features

• session: centralize provider retry coordination (terminal vs transient, Retry-After, no live-step replay after side effects) by @wqymi in #2216
• session: scope replace-agent base override to main/peer actors so subagents keep their own agent prompt by @MiMoHardFather in #2264
• session: allow relative paths within the workspace for file/search tools by @yanyihan-xiaomi in #2251
• session: defer text part creation until first delta (no empty text shells in DB) by @wqymi in #2193

• mcp: show MiMoCode branding in OAuth callback pages and DCR client registration by @MiMoHardFather in #2301
• compose-next: require spec to land in the worktree (pipeline grill → workspace → spec → implement) by @yanyihan-xiaomi in #2307

• skill: move drive-mimo to repository scope (.mimocode/skills/) instead of the product-wide builtin bundle by @yanyihan-xiaomi in #2210
