 # Data Flow
 
+## Code conversation metadata
+
+Main 的 `.makelore/conversations.json` schema v2 是 Conversation 标题和归档状态的唯一权威。新建自动命名会话由 Main 生命周期订阅从首条真实、完整用户消息提取标题；未命名会话的历史 hydration 可补齐同一次命名。串行存储重查 `titleMode` / `autoTitleSet`，手动命名和已删除记录不会被后续事件覆盖。内部命名字段不进入公共 DTO，也不向 Pi session title 双写。
+
+重命名、归档和恢复经现有 Host API 修改元数据；`conversation.metadata-changed` 在现有 SSE 上只传项目和会话身份，不伪造运行时 generation/seq。Renderer 合并列表刷新、在重连时重新读取列表，并拒绝跨项目或早于本地变更的旧结果。归档不 dispose runtime、不移动 JSONL；Main 阻止归档会话的新 prompt/steer/follow-up 与 fork，保留已接受请求、现有任务、审批与中止能力。

 ## Cloud knowledge embedding
 
 MakeLore 知识库 → Yuxi 已启用 embedding 目录与知识库/发布快照 → Yuxi 直连供应商 → Milvus 索引或查询。向量费用由平台承担，不进入 one-api/Works Square 模型目录、用户用量、词元点数或智能体金额预算。下述既有受管模型能力链不作为云知识库 embedding 入口；聊天及其他原有网关能力保持。访问资格和实际运行时限仍由云执行检查。

+# Task: Merge coding conversation management into main
+
+## Identity
+
+- Task ID: 20260920-merge-coding-sessions-bfb69ebb
+- Mode: Integration
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: d61226532a5946af4a0b12b4eb02ce9059d20ddb
+- Owner: codex
+- Status: Ready for Integration
+
+## Scope
+
+- Fast-forward completed source fd0293fe3d94b5a7725cff992ca94f129a6ac889 into local main and promote the accepted Code conversation title/archive ownership and behavior.
+
+## Intent And Constraints
+
+- User requested main integration and explicitly confirmed releasing completed owner 20260920-merge-account-ui-38b91cd6 and adopting the three original untracked task documents unchanged. Official release/start/status succeeded; this task exclusively owns main and the integration lock at the recorded base.
+- Concurrent Task Gate and Planning Gate Passed. Read entry, active task, memory index, positioning/current-state, Pi ADR-006, architecture/domain/success criteria, relevant evidence/reflection/commitment context and all 145 peer scope/intent/promotion sections. Historical placeholders remain unknown/read-only without a concrete conflicting dependency. The current skill takes precedence over legacy local shared-document restrictions and reflection advice.
+- User explicitly replaced the earlier model-generated-title proposal with first-user-message titles; this implementation and promotion honor that amendment. Preserve Main ownership, running work and manual/historical titles. Source task records stay read-only. No subagents, unrelated product changes, remote push, packaging or deployment.
+
+## Outcome
+
+- Fast-forwarded local main from d612265 to fd0293f without conflicts. The merge includes archive/restore, shared rename UI and one-shot first-user-message titles without a model call.
+- Promoted the accepted metadata flow, module ownership and domain behavior in data-flow, module-map and business-rules; recorded the source commit under current-state Integrated Through. The source task record was imported unchanged.
+- The original untracked documents 20260901-package-122-c5e8.md, 20260901-package-123-d7f3.md and 20260902-client-hang-diagnosis-a47c9e2b.md remain outside the integration commit.
+
+## Verification
+
+- Source ancestry confirmed a direct fast-forward; the source worktree was clean at fd0293f. After merge, both the complete product tree and source task record match fd0293f exactly.
+- Reuse exact-source verification because the fast-forward introduces no product edits: 114 focused tests plus one pressure test, one Electron rename/archive/restore fixture, frontend typecheck, lint (0 errors, 8 existing warnings), and Vite Renderer/Main/preload/utility build passed. Real pinned Pi 0.84.2 history hydration was covered locally; no live Provider turn is claimed.
+- Explicit Main TypeScript checking retains baseline failures: source comparison found 89 baseline and 88 current diagnostics, with no added diagnostics. This integration does not broaden scope to those pre-existing errors.
+- git diff --check and the task-aware documentation drift check passed. The latter confirms imported source provenance and that all three adopted foreign documents are unchanged. Source registry/readiness, clean status, branch and latest HEAD match the committed source record.
+
+## Follow-ups
+
+- Source task 20260920-coding-session-controls-10fee632 is retained awaiting cleanup confirmation at D:\Datas\OthersProjects\.codex-worktrees\makelore\20260920-coding-session-controls-10fee632, branch codex/20260920-coding-session-controls-10fee632-coding-session-controls. Its latest result is integrated; removing the checkout also removes ignored dependencies/build output while preserving branch and commits. Main is not a cleanup candidate.
+- An updated client build/install is needed to expose the feature in an installed app; this task only integrates source locally.
+
+## Promotion Candidates
+
+- Accepted and promoted: Main metadata owns stable manual/historical and first-user-message automatic titles; archive preserves running work; list metadata invalidation is separate from sequenced runtime patches. The user's explicit amendment supplies the product decision; Pi runtime and Provider ownership remain unchanged.

 # Business Rules
 
+## Code conversation titles and archive
+
+- 新建自动命名会话使用首条真实、完整、非空用户消息的首行，合并空白并截取最多 32 个 Unicode 字符；纯图片消息使用“附件对话”。斜杠命令、乐观消息和助手输出不触发命名；不调用模型生成标题。
+- 自动标题只设置一次。手动重命名去除首尾空白、最多 200 字符，并始终优先；历史会话和分支会话按手动标题处理，不自动回填或覆盖。仅标题变化不改变会话排序时间。
+- 归档只是会话列表管理，不删除历史、不停止正在运行的任务。已归档会话可查看、审批和中止既有工作；新 prompt/steer/follow-up 与 fork 必须先恢复，已接受请求的去重结果仍可读取。
+- 每个 Agent 提供归档数量及归档列表。归档最后一条最近会话时不自动创建替代会话；恢复沿用原会话并回到最近列表。菜单操作不应隐式切换或准备目标会话。
