feat: connect conversations with Magic Notes

Let users retain useful assistant replies or complete conversations without
leaving their chat workflow. Preview and edit captured text, choose an existing
note or atomically create a note with its first entry, and return to the source
conversation or message from saved records.

Add an application-scoped Notes workbar tab with title/body search and quick
text appends. Preserve drafts across conversation switches and guard closing,
replacement and disabling. Schema 48 stores optional source metadata without
rewriting file-backed bodies; source deletion retains the saved note. Older
clients cannot reopen an upgraded database without a pre-upgrade backup.

Release note: 可将助手回答或完整会话预览、编辑后加入魔法笔记，并从笔记返回原会话或消息。右侧快速笔记支持搜索和追加文字，切换会话保留草稿；采集本身不调用模型，保存后自动评论仍遵循已有设置。

Validation: isolated HEAD-based candidate passed 22 files / 930 focused tests,
plus 20 gateway tests after including its create-result fixture adjustment.
Real Electron App/preload/IPC/SQLite acceptance passed for all 502 historical
messages, exact-entry/source navigation, native keyboard input in a 214px
panel, reopen and source-deletion retention, with zero capture model calls.
Repository lint and web TypeScript passed. Cached whitespace and secret-pattern
checks passed; native-client changes and unrelated IPC extraction are excluded.

Validation limits: the isolated source tree reuses installed node_modules,
where a parallel task upgraded DSH from the committed 0.1.2-rc.1 to 0.1.7-rc.2.
Full typecheck reports 14 DSH errors in three unchanged files; the full-suite
attempt with --bail=1 also fails in deepseek-harness-host.test.ts. These are not
all-green repository or release-package results. Earlier execution-time full
suite failures and fixture repairs remain recorded in the feature progress doc.

+
+## 内容与来源
+
+FR-2、FR-3：单条采集读取所选助手消息的非空正文；整段采集先加载该会话完整历史，再按消息顺序收录用户和助手的非空正文，保留角色分隔。预览建立后，切换会话或收到新消息不会替换正文及来源标识。生成中的消息不可采集，停止或失败后已有正文可保存，单条预览注明回答未完成。整个会话正在生成时禁用整段采集，提示等待完成或停止生成。
+
+首版按文字保存，保留原始 Markdown 文本、换行和代码文本，不承诺还原聊天渲染效果。推理、工具调用日志、系统提示、附件二进制和图片不进入正文；预览持续说明保存范围。用户可编辑预览，来源仍指向本次采集的会话。读取完整会话失败时不以屏幕上已有消息代替。
+
+FR-5：来源独立于可编辑正文。单条来源包含会话和消息标识；整段来源包含会话标识、此次收录的消息标识及采集时间。预览使用采集时的会话标题和项目名称；保存时主进程校验消息归属，并以当时数据库中的会话标题和项目名称写入来源，无项目时显示全局。若预览期间源会话或消息已删除，保存失败并保留预览。保存完成后，修改或删除源消息不回写笔记正文和来源。
+
+点击来源时读取完整会话。消息不存在但会话仍在时打开会话并提示“原消息已不存在”；确认会话不存在后保留来源文字，并在当前来源条禁用跳转。其他读取失败显示可重试错误。打开未渲染的来源消息时扩大聊天历史显示范围，再滚动定位并聚焦。编辑笔记正文不移除来源；删除笔记不影响源会话。
+
+## 面板与草稿
+
+FR-1、FR-4：笔记应用为可关闭、可排序的单实例工作栏 Tab，新布局默认不打开。再次触发入口激活现有 Tab；笔记选择属于应用级状态，切换项目或会话不改写它。列表按置顶优先、最近更新时间排列，搜索匹配标题与记录文字，同一笔记只显示一次。当前应用会话内保留最近选择，重启不恢复笔记选择或草稿。该笔记已删除时回到列表，清除失效保存目标并保留待保存文字。
+
+FR-2、FR-3：面板有浏览、采集编辑、保存中三个状态。触发采集进入编辑态；选择目标只改变写入位置；明确点击“加入笔记”才写入。每次提交新增一条记录，不覆盖旧记录。新建目标时先填写标题，会话标题作为可修改默认值；提交一次创建笔记和首条记录，取消不遗留空笔记。普通“新建笔记”仍可显式创建空笔记。
+
+保存中禁用重复提交和面板离开操作，结果返回后可再次操作。成功后清除本次草稿，显示响应返回的新增记录；失败保留预览、标题和目标。目标已删除时提示重新选择。容量校验使用现有文字记录限制，超限由用户缩减正文后重试；一次提交始终对应一条完整记录。
+
+关闭 Tab、返回面板列表、从面板打开完整工作区、禁用应用或以另一条采集替换草稿前，显示“继续编辑 / 放弃草稿并切换”确认。普通主页面、项目和会话切换以及隐藏工作栏保留 App 持有的草稿及来源。取消采集只在正文或标题相对预览初值有修改时确认；未修改预览可直接取消。完整工作区自身的编辑草稿仍由其离开确认保护。
+
+FR-6：成功写入触发现有通知刷新视图；面板重新挂载或工作栏重新展开时读取最新数据。面板挂载期间保留搜索词；笔记选择和草稿由 App 保留，不受搜索响应或后台刷新覆盖。既有记录编辑继续使用原修订号处理冲突。此处同步仅指本机共享存储的视图更新。
+
+## 启用与评论
+
+FR-1～FR-4：遵循魔法笔记应用的启用状态。禁用时隐藏会话采集、快速笔记及工作栏目录入口，并移除笔记 Tab；禁用前处理草稿。外部设置变更要求禁用时，选择继续编辑会尝试恢复启用设置，失败显示设置错误。应用未常驻不影响快速入口或工作栏可用性。设置继续由应用中心管理。
+
+会话采集和快速追加本身不调用模型。保存后沿用现有 AI 评论模式；只有已有设置要求保存后自动评论时才触发，失败不撤销保存，也不自动重新追加。
+
+## 完整性检查
+
+当前实现覆盖首次创建、追加、取消、重复点击、写入失败、目标删除、来源删除、跨会话切换及刷新与草稿的关系。完整历史读取、来源定位和存储接口已接入；产品范围无待决项。真实 Electron 已验证采集、保存、定位、窄面板键盘操作和持久化，具体范围见进展记录。全仓测试和类型检查仍有执行时记录的失败，聚焦复跑通过不等于全仓通过。

 # Magic Notes Progress
 
+## 2026-09-26: Conversation Capture and Compact Notes Panel
+
+- FR-1/FR-4: `notes` is an application-scoped optional singleton in the workbar.
+  The compact panel supports title/body search, browsing, text appends and full
+  workspace navigation. Quick notes uses the same tab; app enablement controls
+  availability independently of sidebar pinning.
+- FR-2/FR-3: Assistant-message and conversation-header actions open editable text
+  previews. Whole-conversation capture loads complete history. App owns drafts
+  and selection; close, replacement and disable actions use the draft guard.
+  Success focuses the returned entry ID; failed saves retain input.
+- FR-5: Schema 48 adds nullable source metadata. Main validates message ownership
+  and resolves display labels at save time. Panel and workspace share source
+  navigation, including missing-message and missing-conversation handling.
+- FR-6: Desktop search, preload/IPC and note-level SQL results are connected.
+  Creating a note with initial content commits note/entry membership in one
+  transaction. Both views use existing change notifications; file reconciliation
+  and workspace optimistic revisions retain their existing boundaries. See
+  [the implemented contract](./technical-design.md#conversation-integration).
+
+Validation reported by implementation subagents in this session:
+
+| Scope | Reported result | Evidence boundary |
+| --- | --- | --- |
+| Backend focused checks | 362 tests passed | Subagent handoff; not a repository-wide result |
+| Frontend focused checks | 8 files / 592 tests passed | Subagent handoff; not real Electron acceptance |
+| Web TypeScript and lint | Passed | Subagent handoff; does not establish full-repository typecheck/lint |
+
+The coordinating agent subsequently reported real Electron acceptance passing.
+[magic-notes-capture.electron.test.ts](../../../tests/magic-notes-capture.electron.test.ts)
+and its [Main driver](../../../tests/support/magic-notes-capture-main.ts) /
+[renderer](../../../tests/support/magic-notes-capture-renderer.tsx) mount the real
+App UI and use production preload, registered IPC and SQLite/file storage.
+Unrelated services use test dependencies; the renderer bridge is not replaced.
+
+- Saving an assistant response to an existing note retains its earlier entry;
+  whole-conversation capture creates a new note with its first entry.
+- All 502 historical messages are compared verbatim in the preview and saved
+  content, including history initially outside the rendered timeline.
+- Full-workspace navigation locates the exact saved entry; source navigation
+  restores the conversation and focuses the source message. The coordinating
+  agent also reports source-history expansion coverage.
+- Native Electron keyboard input covers returning to the list, opening a note
+  and appending text in a measured 214px panel, without horizontal overflow.
+- SQLite close/reopen preserves both notes. Deleting the source conversation
+  retains their saved content and source metadata. Model calls: **0**.
+
+The combined Electron, `canvas-ipc.integration`, `MagicNotesPanel` and
+`ChatTimeline` run passed **4 files / 70 tests**. Lint and web TypeScript passed.
+This validates the App capture path in a test Electron window with isolated data;
+it does not establish release-package or cross-platform acceptance.
+
+Repository validation and subsequent fixture repairs:
+
+| Check | Result at execution time | Follow-up |
+| --- | --- | --- |
+| `npm test` | 457 files / 5,359 cases: 5,272 passed, 4 failed, 83 skipped | No all-green full-suite rerun reported |
+| Three schema-fixture failures | Activity-history and two worker fixture variants omitted `DROP COLUMN source_json` when reconstructing old schemas | Fixed; the five-file regression run below passed |
+| Remaining test failure | `tests/build-release.test.ts`: missing DSH resources | Unrelated to notes; not fixed in this validation pass |
+| Full-repository typecheck | Failed on parallel SSH mocks missing `forwardLoopback`, an IPC native-terminal fixture referencing undefined `terminalManager`, and mismatched arguments in `obsidian-runtime-acceptance` | Execution-time findings; later concurrent changes may alter them |
+
+After fixture repairs, **5 files / 58 tests passed**:
+`src/main/assistant/activity-history-io.test.ts`,
+`tests/assistant-storage-worker.test.ts`,
+`src/main/assistant/assistant-storage-upgrade.test.ts`,
+`src/main/magic-notes/magic-note-storage.test.ts` and
+`src/main/magic-notes/canvas-ipc.integration.test.ts`.
+This focused rerun does not replace the failed full-suite/typecheck results.
+
+Status: **implemented; real Electron acceptance passed; repository validation is
+not all green**. Results above come from the session handoffs, not a rerun by this
+documentation task. Later fixes require their own verification evidence; older
+Electron/full-suite results below do not validate this integration.

+
+### Workbar and Capture
+
+`WORKBAR_APP_DEFINITIONS` registers `notes` as an optional, closable, reorderable
+singleton with application scope, no `targetRef` and `defaultOpen: false`.
+`RightAssistantSidebar` opens or activates it through the existing
+[workbar tab model](../assistant-workbar/terminal-tabs-prd.md), and removes it when
+Magic Notes is disabled. Sidebar pinning does not control this availability.
+`MagicNotesPanel` renders the compact view; `WorkbarShell` supplies the shared tab
+controls. The footer shortcut and collapsed-sidebar chat-header shortcut both
+activate the same instance.
+
+`App.captureToNote` receives the message identity from `ChatTimeline`, or calls
+`ensureConversationHistory` for whole-conversation capture. It freezes text and
+source IDs before opening the preview and waits for queued conversation persistence
+so Main can validate newly completed messages. Whole-conversation text includes
+nonempty user/assistant bodies with role headings. It excludes reasoning, tool
+logs and attachment binaries, and rejects streaming conversations.
+
+`useMagicNoteDraft` lives in App and owns the draft, selected note, saving state
+and one shared confirmation promise. Selection and drafts survive panel remounts
+and conversation/project switches, but are not persisted across app restarts.
+The guard rejects leaving while saving and confirms discarding pending input;
+explicit cancellation compares text/title with their initial preview values.
+Application disablement and tab closing call the same guard. Workspace navigation
+also passes through the full workspace's existing leave check.
+
+`capturedNoteContent` converts text into v1 Quill string inserts, preserving
+newlines and adding the terminal newline when needed. It splits inserts at the
+200,000-code-unit operation limit without splitting surrogate pairs; the complete
+record still passes the shared rich-content schema. Markdown stays literal text.
+No summarization or attachment copying runs during capture. New-note titles are
+limited to 100 characters. A synchronous submission ref prevents duplicate writes.
+
+`magicNotes.create({ title, content?, source? })` returns `MagicNoteCreateResult`,
+with `createdEntryId` when initial content exists. `createMagicNote` inserts the
+note, first entry, source and derived todos inside one SQLite transaction; failure
+leaves no committed empty note and sends no success notification. This atomicity
+applies to database membership; filesystem writes retain the reconciliation
+boundary in [File Storage and Writes](#file-storage-and-writes).
+`magicNotes.createEntry({ noteId, content, source? })` always returns the exact
+`createdEntryId`. The panel uses that ID to scroll, focus and briefly highlight the
+new record. Opening the full workspace passes `{noteId, entryId?, requestId}` into
+its existing guarded note-navigation path.
+
+`magicNotes.search({ query, limit? })` is exposed by `DesktopApi`, preload and
+`magic-notes:search`. Trusted-sender and shared-schema validation precede
+`AssistantDatabase.searchMagicNoteSummaries`. The trimmed query has a 1,000-character
+limit; result limits are 1-200, defaulting to 200. The panel requests 100 results
+and debounces nonempty queries by 180 ms. SQL searches note titles or indexed entry
+text using `EXISTS`, so each note occurs once before `LIMIT`. Empty queries list
+notes; ordering is pinned first, then updated time and row ID descending.
+`%`, `_` and backslashes are escaped for literal matching. Agent `note_search`
+retains its separate entry-level output and 1-100 limit.
+
+### Source Metadata
+
+`magicNoteSourceSchema` defines `kind` (`message` or `conversation`),
+`conversationId`, nonempty unique `messageIds`, ISO `capturedAt`,
+`conversationTitle`, and optional `projectId` / `projectName`. A message source
+requires exactly one message ID. Create/create-entry inputs accept `source`;
+note creation requires initial content when source is supplied. Entry reads
+return it independently of editable content, while update inputs cannot replace it.
+
+The IPC helper `resolveMagicNoteSource` loads the stored conversation and verifies
+that every message ID belongs to it; a single-message source must identify an
+assistant message. It replaces renderer-supplied title/project labels with current
+database values while retaining the supplied capture time and IDs. Preview labels
+therefore describe capture time, but stored labels describe save time. Missing
+source rows reject creation; later source deletion does not block note reads or edits.
+
+Schema 48 adds nullable `magic_note_entries.source_json` in a transaction and
+advances `PRAGMA user_version`. Existing entries read without a source. It adds no
+conversation foreign key or deletion cascade, and does not rewrite file-backed
+bodies. Schema 38 remains the historical body migration. Structure-only upgrade
+does not independently trigger body conversion or VACUUM; see the
+[database migration guide](../../development/database-migrations.md). Coordinated
+SQLite/files backups include the source metadata.
+
+`MagicNoteSource` is shared by panel summaries and workspace records. Its callback
+`App.openNoteSource` reads `conversations.get`, then navigates through the workspace
+leave guard. Message navigation increases the mounted timeline range before
+scrolling and focusing. A missing message opens its conversation with a notice;
+a confirmed missing conversation disables that source bar's jump buttons. Other
+read errors remain retryable. No deleted-source flag is stored.
+
+### Refresh and Validation
+
+Both views use the same Main store and `magic-notes:changed` notification. The
+panel reloads search and selected detail when active, and ignores superseded
+responses. Search/loading state belongs to the mounted panel; input and selected
+note belong to App. A deleted selected note clears the selection and matching
+target ID while preserving draft text. Read and save failures have local recovery
+feedback. The full workspace retains its existing revision and dirty-editor rules.
+
+After a successful save, only `after-save-auto` starts entry analysis using the
+returned `createdEntryId` and configured comment format. Analysis errors notify
+without undoing the save or recreating the entry. Other comment modes perform no
+panel analysis.
+
+Regression cases are in `MagicNotesPanel.test.tsx`, `App.test.tsx`,
+`ChatTimeline.test.tsx`, `MagicNotesWorkspace.test.tsx`, workbar contract tests,
+database/storage tests and production preload/IPC integration tests.
+`tests/magic-notes-capture.electron.test.ts` mounts the real App with production
+preload and capture IPC, backed by SQLite/files. It validates existing/new-note
+saves, verbatim 502-message history, workspace/source navigation, native keyboard
+input in a narrow panel, database reopen and retention after source deletion,
+with zero model calls. Failed writes and external refresh retain their focused
+regression coverage; this Electron result does not claim every failure path.
+Repository test/typecheck failures and repaired migration fixtures are documented
+separately in [progress](./progress.md).
