fix(mcp): write page body before title to avoid split-brain on failure (#159)

updatePage (markdown) and updatePageJson wrote the title via REST FIRST, then
the body via collab. If the body write failed (e.g. a collab persist timeout),
the page was left with the NEW title over its OLD body — a split-brain the tool
reported as an error but never repaired (red-team finding #10).

Reorder both: write the body first, and only set the title after the body has
persisted. Now a body-write failure leaves the title untouched (no split-brain).
A title write failing after a successful body is rarer (REST is fast) and leaves
correct content under a stale title — the strictly lesser inconsistency — which
is the same trade-off the issue's "atomic, or roll back the title" intends,
without the fragility of a rollback write that could itself fail.

No unit test: both paths require a live collab provider and the suite has no
provider mock; the change is a pure reordering. All 306 mcp tests still pass.

 ### Added
 
-- **Persistent AI-chat history as the source of truth + server-side export.**
-  An assistant turn is now persisted to the database step by step: the row is
-  inserted upfront as `streaming` and updated as each agent step finishes, then
-  finalized once to `completed`/`error`/`aborted`. A process that dies mid-turn
-  keeps every finished step, and a startup sweep flips any dangling `streaming`
-  row (untouched for 10 minutes) to `aborted`. Chat "Copy" now exports
-  server-side from these rows (`POST /ai-chat/export`) rather than from live
-  client state, so the export is identical whether a chat is freshly streaming,
-  just switched to, or reloaded — and is available from the first turn of a new
-  chat. (#183, #174)
-
 - **AI-agent attribution for MCP writes.** Comments (and pages) created through
   the MCP endpoint by a dedicated agent account are now badged as "AI", with
   unspoofable provenance derived from a per-user `is_agent` flag (not from the
-  request body). **Operator setup:** use a _dedicated_ service account for the
+  request body). **Operator setup:** use a *dedicated* service account for the
   MCP fallback and set the flag with SQL —
   `UPDATE users SET is_agent = true WHERE email = '<mcp-account>'`. Never flag a

   the base URL, since a custom URL can front real OpenAI too. (#175, #177)
-- **Per-MCP-server instructions in the agent prompt.** Each external MCP server

+
+`apps/server/src/core/ai-chat/ai-chat.service.ts`. В PR #49 извлечён и
+покрыт только чистый `buildErrorAssistantRecord`. Полные интеграционные
+сценарии всё ещё отложены:
+
+- **Запись чата, упавшего на первом ходу** (`onError`) — ассистентская
+  запись об ошибке должна сохраняться, даже когда первый ход стрима падает.
+- **Жизненный цикл external-MCP клиентов** — клиенты закрываются и при
+  `throw`, и при `onFinish` (нет утечки соединений).
+- **Анти-tamper: история восстанавливается из БД, а не из `body.messages`** —

+Эти сценарии требуют сидирования SDK `streamText` (инъекция/seam колбэков

+Статус: **частично закрыто.** Квирк «node как объект ИЛИ JSON-строка» вынесен
+в общий хелпер `parseNodeArg` (см. «Прогресс» ниже); остальной долг (единый
+реестр спеков + унификация конвертера) всё ещё открыт. Это forward-looking
+стоимость поддержки, НЕ баг — код корректен сегодня. Держим запись открытой,
+чтобы при росте набора инструментов долг не разъезжался молча.
+
+## Прогресс
+
+- ✅ **Квирк node-arg вынесен в хелпер** (`refactor/ai-chat-tool-spec-registry`,
+  PR #114). Шесть рукописных копий нормализации «node как объект ИЛИ
+  JSON-строка» свёрнуты в `parseNodeArg`: по одному источнику на пакет —
+  `packages/mcp/src/lib/parse-node-arg.ts` (standalone) и
+  `apps/server/src/core/ai-chat/tools/parse-node-arg.ts` (in-app). Две копии
+  намеренны (ESM/CJS-граница), поведение тождественно.
+- ⏳ **Единый реестр спеков** (схема + описание на инструмент) и **вывод
+  `DocmostClientLike` из реального типа** — отложены (см. «Фикс»): требуют
+  пересечения ESM/CJS-границы для данных+zod и ломают тест-стабы in-app
+  инструментов при точных типах. Делать инкрементально.
+- ⏳ **Унификация конвертера ProseMirror ↔ Markdown** — открыта (см. раздел
+  «Расширение …» ниже); на неё опирается план git-синка
+  (`docs/git-sync-plan.md`).
+
+## Суть
+
+Один и тот же набор инструментов поверх одного `DocmostClient` описан
+**тремя независимыми рукописными слоями**. Каждое добавление инструмента или
+правка его model-facing описания требует синхронной правки в 2–3 местах, а
+parity-баги (расхождение копий) приходится чинить/переоткрывать дважды.
+
+## Где дублируется (три слоя)
+
+1. **Standalone MCP-сервер** — `packages/mcp/src/index.ts` (~38 `registerTool`).
+   Для внешних MCP-клиентов (stdio/http). На каждый инструмент: zod-схема +
+   длинное model-facing описание + тонкий `execute`, вызывающий `DocmostClient`.
+2. **Встроенный AI-чат** — `apps/server/src/core/ai-chat/tools/ai-chat-tools.service.ts`
+   (~39 `tool({...})` через `ai`-SDK). Своя zod-схема + своё описание + свой
+   `execute` поверх ТОГО ЖЕ клиента (`@docmost/mcp` грузится в
+   `tools/docmost-client.loader.ts:188` через динамический `import()`).
+3. **Ручная копия сигнатур** — интерфейс `DocmostClientLike` в
+   `apps/server/src/core/ai-chat/tools/docmost-client.loader.ts:9` (в комментарии
+   прямо: «Signatures here mirror that file exactly»), скопирован руками из
+   `packages/mcp/src/client.ts`.
+
+## Что именно продублировано (с подтверждением по коду)
+
+- **zod-схема + описание** каждого инструмента — в слоях 1 и 2 целиком.
+- ~~**Квирк «node как объект ИЛИ JSON-строка»** реализован дважды (НЕ в общем
+  клиенте)~~ — **закрыто (PR #114):** вынесен в `parseNodeArg` (по хелперу на
+  пакет), 6 inline-копий устранены:
+  - in-app: `patchNode`, `insertNode`, `updatePageJson` →
+    `apps/server/src/core/ai-chat/tools/parse-node-arg.ts`;
+  - standalone: `patch_node`, `insert_node`, `update_page_json` →
+    `packages/mcp/src/lib/parse-node-arg.ts`.
+- **Guardrail/семантика `transformPage` (dryRun)** описана в обоих:
+  `ai-chat-tools.service.ts:~935` и `index.ts:~1006`.
+
+## Почему разделение слоёв 1 и 2 само по себе оправдано
+
+У путей разный транспорт и auth-контекст, и это правильно держать раздельно:
+in-app путь чеканит per-user JWT + provenance collab-токен (подписанная
+agent-claim, `docmost-client.loader.ts:159` — `getCollabToken`; см. план §6.5),
+а standalone обслуживает внешних клиентов по stdio/http. **Но** это оправдывает
+два тонких адаптера (`execute` + auth-обвязка), а НЕ две рукописные копии
+МЕТАДАННЫХ (схема + описание + квирки). Метаданные можно объявить один раз и
+переиспользовать обоими транспортами.
+
+## Доказательство стоимости (наблюдалось при фиксе edit_page_text)
+
+При исправлении ложного «успеха» `edit_page_text` (refuse форматных правок +
+`verify`-отчёт):
+- **Поведение** легло в общий `DocmostClient` → автоматически дошло до обоих
+  агентов ОДНОЙ правкой. Это «хороший» случай — логика в едином источнике.
+- **Описание** инструмента пришлось править ДВАЖДЫ: в `index.ts` (кодером) и
+  отдельно в `ai-chat-tools.service.ts:617`, где описание продолжало рекламировать
+  «Markdown wrappers tolerated via strip-and-retry» — ровно ту формулировку, что
+  ввела исходного агента в заблуждение. Копия молча разъехалась и какое-то время
+  встроенный агент получал устаревшую подсказку. Это и есть материализованный
+  parity-баг.
+
+## Расширение: дублируется не только описания инструментов — ещё и конвертер (PM ↔ Markdown)
+
+Зафиксировано при планировании встраивания git-синка (`docmost-sync` → gitmost,
+нативная in-process интеграция). Та же болезнь «несколько рукописных копий одного
+кода» теперь касается слоя конвертации ProseMirror ↔ Markdown и его lib, а не
+только метаданных инструментов.
+
+- **Копия в gitmost** — `packages/mcp/src/lib/`: `markdown-converter.ts` (~885
+  строк), `markdown-document.ts` (~136), `node-ops.ts`, `diff.ts`,
+  `docmost-schema.ts`. Канонизатора (`canonicalize.ts`) здесь НЕТ.
+- **Копия в docmost-sync** — `packages/docmost-client/src/lib/`: тот же набор +
+  `canonicalize.ts` (~11 КБ, держит идемпотентность round-trip, SPEC §11) +
+  `markdown-document.ts` с режимом «тело + якоря, без тредов комментов»
+  (`includeCommentThreads:false`, на ~20 строк больше).
+- **Третья копия (планируется)** — план git-синка вендорит чистую часть
+  конвертера в новый `packages/git-sync` (collab-файл не нужен: запись идёт
+  нативно через `openDirectConnection` + `@docmost/editor-ext`).
+
+Копии уже молча разъехались (docmost-sync vs `packages/mcp`): `collaboration.ts`
+~329 изменённых строк, `node-ops.ts` ~53, `markdown-converter.ts` ~24,
+`markdown-document.ts` ~20. Отдельно: `docmost-schema.ts` в lib дублирует
+**реальную** схему сервера `@docmost/editor-ext` (её использует collab/persistence)
+— расхождение схем = риск битой конвертации нод.
+
+Вывод: тот же фикс-вектор (единый источник правды), что и для инструментов, стоит
+распространить на конвертер — общий пакет конвертации, потребляемый `mcp`,
+`git-sync` и (в идеале) сервером. До конвергенции git-sync держит вендоренную
+копию валидированного конвертера с гейтом round-trip против схемы `editor-ext`
+(осознанный долг «третья копия сейчас, объединяем позже»).
+
+## Фикс
+
+Единый реестр спеков (полное устранение дублирования).** Вынести в
+  `packages/mcp` один источник на инструмент: `name` + zod-схема + model-facing
+  описание + общий хелпер нормализации node-строки (для patch/insert/update).
+  И `index.ts`, и `ai-chat-tools.service.ts` импортируют спеки и добавляют только
+  свой `execute`/auth. `DocmostClientLike` — выводить из типа реального клиента
+  (type-only import / генерация), а не копировать руками.
+  - Ограничение: `@docmost/mcp` — ESM-only, сервер грузит его через трюк
+    `new Function('import(specifier)')` (`docmost-client.loader.ts:174`), потому
+    что `module:commonjs` даунлевелит `import()` в `require()`. Реестр спеков
+    (данные + zod) должен пересекать ту же ESM/CJS-границу — выполнимо тем же
+    динамическим импортом; `ai`-SDK `tool()` и MCP `registerTool()` имеют разную
+    форму, поэтому реестр экспортирует транспорт-агностичные `{name, schema,
+    description}`, а каждая сторона оборачивает их сама. `zod` — общая зависимость
+    обоих пакетов, типы переносятся.

+# Git-sync: спека реализации (встраивание docmost-sync в gitmost)
+
+Статус: **спецификация, код не менялся.** Детальный план реализации фичи
+«двусторонний синк страниц Docmost ↔ локальная git-папка Markdown», встроенной
+прямо в gitmost.
+
+Источник движка: `https://gitea.vvzvlad.xyz/vvzvlad/docmost-sync`
+(ветка `main`, на момент спеки HEAD `b03eb35`). Все сигнатуры ниже сверены с этим
+исходником и с текущим кодом gitmost.
+
+Предыстория и обоснование архитектурных развилок — в бэклоге
+[ai-chat-tool-definitions-duplicated.md](backlog/ai-chat-tool-definitions-duplicated.md)
+(раздел про дублирование конвертера) и в исходном `SPEC.md` репозитория
+docmost-sync (нумерация §-параграфов ниже ссылается на него).
+
+---
+
+## 0. Зафиксированные решения
+
+Из обсуждения архитектуры (выбор пользователя) и трёх суб-решений:
+
+1. **Нативная in-process интеграция.** Никаких REST-к-себе и сервис-юзера: чтение
+   через репозитории gitmost, запись тела — через collab `openDirectConnection`,
+   триггеры — через `EventEmitter2` вместо поллинга `/recent`.
+2. **Встроенный NestJS-модуль** `GitSyncModule` в `apps/server/src/integrations/git-sync`
+   с `@Interval`/событиями и **leader-lock на Redis** (single-writer при нескольких
+   репликах).
+3. **Настройка по спейсам в UI** — флаг в `space.settings.gitSync`, секреты
+   (git-remote) — через ENV/`EnvironmentService`.
+4. **Конвертер** — вендорим *чистую* часть из docmost-sync в `packages/git-sync`,
+   гейт = round-trip-идемпотентность против схемы `@docmost/editor-ext`.
+5. **Vault** — **репозиторий на спейс**; `move-to-space` = кросс-репо delete+create.
+6. **Провенанс** — отдельное значение `lastUpdatedSource = 'git-sync'`.
+
+Вне scope v1 (как и в SPEC): комментарии (только якоря, без тредов), права/ACL,
+вложения как отдельный поток (едут ссылками внутри контента), realtime-подписка
+на Hocuspocus (остаётся поллинг-страховка + события).
+

+
+Ключ интеграции: движок docmost-sync уже **полностью построен на dependency
+injection** — весь внешний IO (REST-клиент, git, файловая система) передаётся
+через узкие интерфейсы. Мы НЕ переписываем движок; мы подставляем нативные
+реализации в его DI-швы.
+
+---
+
+## 2. Состав вендоринга из docmost-sync
+
+В новый пакет `packages/git-sync` копируем (с сохранением истории смысла —
+backport-friendly, как сделано с `packages/mcp`):
+
+### 2.1. Движок (engine) — `src/engine/`
+| Файл | Что несёт | IO | Берём |
+| --- | --- | --- | --- |
+| `pull.ts` | Docmost→FS: reconcile + write + commit + merge | client+git+fs (инжектируется) | да |
+| `push.ts` | FS→Docmost: diff + classify + apply + refs | client+git+fs (инжектируется) | да |
+| `git.ts` | `VaultGit` — обёртка git shell-out | системный `git` | да, как есть |
+| `reconcile.ts` | чистый планировщик | нет | да |
+| `layout.ts` | чистый маппер дерево→пути | нет | да |
+| `sanitize.ts` | чистая санитизация имён | нет | да |
+| `stabilize.ts` | fixpoint-нормализация md (SPEC §11) | нет (lib-вызовы) | да |
+| `loop-guard.ts` | `bodyHash` (sha256) | нет | да |
+| `settings.ts` | zod-конфиг | `.env` | **адаптируем** (см. §7) |
+| `index.ts` | тонкий CLI-скаффолд | — | нет (заменяем на NestJS) |
+
+### 2.2. Конвертер (чистая часть) — `src/lib/`
+Из `packages/docmost-client/src/lib/` берём **только** чистый конвертер и формат
+файла (collab/auth REST-части НЕ нужны — запись нативная):
+
+| Файл | Экспорт |
+| --- | --- |
+| `markdown-converter.ts` | `convertProseMirrorToMarkdown(content): string` |
+| `collaboration.ts` (только конвертер-функция) | `markdownToProseMirror(md): Promise<doc>` ⚠️ |
+| `markdown-document.ts` | `serializeDocmostMarkdownBody`, `parseDocmostMarkdown`, `serializeDocmostMarkdown`, тип `DocmostMdMeta` |
+| `canonicalize.ts` | `canonicalizeContent(node)`, `docsCanonicallyEqual(a,b)` |
+| `docmost-schema.ts` | tiptap-схема для `markdownToProseMirror` |
+| `node-ops.ts`, `diff.ts` | трансформации/диф (нужны транзитивно) |
+
+⚠️ `markdownToProseMirror` физически лежит в `collaboration.ts` docmost-client
+(строка 289) — это **чистая** функция (marked→HTML→generateJSON), не путать с
+collab/websocket write-path из того же файла, который НЕ берём.
+
+> **Долг (зафиксирован в бэклоге):** это третья копия конвертера (есть в
+> docmost-sync, в `packages/mcp`, теперь в `packages/git-sync`). Конвергенция в
+> общий пакет — отдельная задача; здесь сознательно вендорим валидированную
+> копию ради сохранения идемпотентности.
+
+### 2.3. НЕ берём
+`pull`/`push` CLI-обёртки, `roundtrip.ts` (харнес переносим в тесты, см. §13),
+`docmost-client` REST-клиент целиком, `lib/collaboration.ts` (websocket-write),
+`lib/auth-utils.ts`, `Makefile`, Docker-обвязку docmost-sync.
+
+---
+
+## 3. Главный шов: `GitmostDataSource`
+
+Движок дёргает Docmost через `Pick<DocmostClient, …>`. Мы реализуем класс,
+**структурно совместимый** с этими сигнатурами, но нативный внутри. Это
+единственный нетривиальный новый код.
+
+### 3.1. Точный набор методов, которых требует движок
+
+Из `pull.ts` (`ApplyPullActionsDeps.client`) и обхода дерева:
+```ts
+listSpaceTree(spaceId: string, rootPageId?: string): Promise<{ pages: PageNode[]; complete: boolean }>;
+getPageJson(pageId: string): Promise<{ id; slugId; title; parentPageId; spaceId; updatedAt; content }>;
+```
+
+Из `push.ts` (`ApplyPushDeps.client`):
+```ts
+importPageMarkdown(pageId: string, fullMarkdown: string): Promise<{ updatedAt?: string; /* … */ }>;
+createPage(title: string, content: string, spaceId: string, parentPageId?: string): Promise<{ data: { id: string }; updatedAt?: string }>;
+deletePage(pageId: string): Promise<unknown>;
+movePage(pageId: string, parentPageId: string | null, position?: string): Promise<unknown>;
+renamePage(pageId: string, title: string): Promise<unknown>;
+```
+
+Для непрерывного режима/детекции удалений (фаза B+, SPEC §8):
+```ts
+listRecentSince(spaceId: string | undefined, sinceIso: string | null, hardPageCap?: number): Promise<any[]>;
+listTrash(spaceId: string): Promise<any[]>;
+restorePage(pageId: string): Promise<unknown>;
+```
+
+### 3.2. Маппинг на нативные сервисы gitmost
+
+| Метод адаптера | Нативная реализация |
+| --- | --- |
+| `listSpaceTree(spaceId)` | `SpaceRepo.findById(spaceId, wsId)` + `PageRepo.getSpaceDescendants(spaceId, { includeContent: false })` → map в `PageNode { id, title, slugId, parentPageId, hasChildren }`. **`complete: true` всегда** (читаем БД, не пагинированный REST) → суппрессия `incomplete-fetch` из SPEC §8 нативно не срабатывает. |
+| `getPageJson(pageId)` | `PageRepo.findById(pageId, { includeContent: true })` → `{ id, slugId, title, parentPageId, spaceId, updatedAt, content }`. `content` — ProseMirror JSON в схеме `editor-ext`. |
+| `importPageMarkdown(pageId, fullMd)` | `parseDocmostMarkdown(fullMd)` → body; `await markdownToProseMirror(body)` → doc; **запись через collab** (см. §3.3). Вернуть `{ updatedAt }` свежей страницы. |
+| `createPage(title, body, spaceId, parent?)` | `PageService.create(userId, wsId, { spaceId, title, parentPageId }, provenance)` → shell; затем тело через collab (§3.3). Вернуть `{ data: { id }, updatedAt }`. |
+| `deletePage(pageId)` | `PageService.removePage(pageId, userId, wsId)` (soft-delete → Trash, обратимо). |
+| `movePage(pageId, parent, pos?)` | `PageService.movePage({ pageId, parentPageId: parent, position }, movedPage, provenance)`. **`position` обязателен** для Docmost-move — вычисляем `fractional-indexing-jittered` ключ между соседями (соседей берём из `PageRepo`). |
+| `renamePage(pageId, title)` | `PageService.update(page, { title }, user, provenance)`. |
+| `listRecentSince` | `PageRepo.getRecentPagesInSpace(spaceId, { … })`, фильтр по `updatedAt > since`. |
+| `listTrash(spaceId)` | `PageRepo` запрос с `deletedAt IS NOT NULL` по спейсу. |
+| `restorePage(pageId)` | `PageService.restore(...)`. |
+
+`userId`/`wsId` берём из конфигурации спейса (сервисный аккаунт воркспейса или
+владелец спейса — см. §7). `provenance` всегда несёт `source: 'git-sync'` (§8).
+
+### 3.3. Нативная запись тела (linchpin)
+
+Подтверждено в коде: `CollaborationGateway.openDirectConnection(documentName, context)`
+([collaboration.gateway.ts:148](../apps/server/src/collaboration/collaboration.gateway.ts#L148-L150))
++ паттерн `withYdocConnection`
+([collaboration.handler.ts:118-133](../apps/server/src/collaboration/collaboration.handler.ts#L118-L133)).
+Имя документа — `page.<pageId>` ([getPageId](../apps/server/src/collaboration/collaboration.util.ts#L163-L165)).
+Схему берём из `tiptapExtensions` ([collaboration.util.ts](../apps/server/src/collaboration/collaboration.util.ts)).
+
+```ts
+// In-process body write — no loopback websocket, no service-user token.
+// Mirrors collaboration.handler.ts 'replace' operation exactly.
+private async writeBody(pageId: string, prosemirrorJson: JSONContent): Promise<void> {
+  const conn = await this.collabGateway.openDirectConnection(
+    `page.${pageId}`,
+    { actor: 'git-sync' }, // provenance flows into PersistenceExtension (see §8)
+  );
+  try {
+    await conn.transact((doc) => {
+      const fragment = doc.getXmlFragment('default');
+      if (fragment.length > 0) fragment.delete(0, fragment.length);
+      const next = TiptapTransformer.toYdoc(prosemirrorJson, 'default', tiptapExtensions);
+      Y.applyUpdate(doc, Y.encodeStateAsUpdate(next));
+    });
+  } finally {
+    await conn.disconnect();
+  }
+  // PersistenceExtension.onStoreDocument persists ydoc+content+textContent
+  // consistently, stamps lastUpdatedSource, broadcasts 'page.updated'.
+}
+```
+
+**Схема-совместимость (критично).** `markdownToProseMirror` производит
+ProseMirror JSON в схеме docmost-client, а `TiptapTransformer.toYdoc` валидирует
+его в схеме `editor-ext`. Аналогично на чтении `convertProseMirrorToMarkdown`
+получает `content` в схеме `editor-ext`. Эти две схемы **должны совпадать по
+именам нод/марок/атрибутов**, иначе ноды потеряются. Это и есть гейт §13.1.
+
+---
+
+## 4. `VaultGit` и git-бинарь
+
+`VaultGit` (engine/git.ts) оставляем как есть — он шеллит в системный `git` через
+`execFile` (args-массив, без инъекций), всегда `cwd=<vaultPath>`. Константы:
+`DEFAULT_BRANCH = "main"`, `BOT_AUTHOR_NAME = "Docmost Sync"`,
+`BOT_AUTHOR_EMAIL = "docmost-sync@local"`; в push.ts: `DOCMOST_BRANCH = "docmost"`,
+`LAST_PUSHED_REF = "refs/docmost/last-pushed"`, провенанс-трейлеры
+`Docmost-Sync-Source: docmost|local`.
+
+**Ops-требование:** в рантайм-образ gitmost добавить пакет `git`
+([Dockerfile](../Dockerfile)) — сейчас его там может не быть. Без бинаря
+`VaultGit.assertGitAvailable()` падает на старте цикла.
+
+**Модель веток (пер-репо, SPEC §5):** `main` (правит человек/файлы) ↔ `docmost`
+(зеркало Docmost, пишет только движок) ↔ `merge-base` как базлайн;
+`refs/docmost/last-pushed` — что из `main` уже отражено в Docmost.
+
+---
+
+## 5. Топология vault: репозиторий на спейс
+
+- Корень: `<DATA_DIR>/git-sync/<spaceId>/` — отдельный git-репо на каждый
+  включённый спейс. `layout.ts` уже спейс-скоупный (корень спейса → `segments: []`).
+- Remote — пер-спейс (из конфигурации спейса/ENV). Изоляция конфликтов, блокировок
+  и blast-radius.
+- `move-to-space` (страница меняет спейс) → **кросс-репо**: `delete` в исходном
+  репо + `create` в целевом. Ловим по событию `PAGE_MOVED_TO_SPACE`.
+- Redis-lock ключ — `git-sync:lock:<spaceId>` (§9).
+
+---
+
+## 6. NestJS-модуль `GitSyncModule`
+
+Структура (шаблон — `McpModule`):
+```
+apps/server/src/integrations/git-sync/
+  git-sync.module.ts
+  git-sync.constants.ts                # QueueJob/event-имена, дефолты
+  services/
+    gitmost-datasource.service.ts      # §3 адаптер
+    git-sync.orchestrator.ts           # @Interval + leader-lock + цикл по спейсам
+    vault-registry.service.ts          # путь vault на спейс, VaultGit-инстансы
+    fractional-index.util.ts           # position для move (reuse server util)
+  listeners/
+    page-change.listener.ts            # подписка на EventName.PAGE_* + debounce
+  git-sync.controller.ts               # (опц.) ручной trigger/status для админа
+```
+
+```ts
+@Module({
+  imports: [DatabaseModule, EnvironmentModule, ScheduleModule.forRoot()],
+  providers: [
+    GitmostDataSourceService,
+    GitSyncOrchestrator,
+    VaultRegistryService,
+    PageChangeListener,
+  ],
+})
+export class GitSyncModule {}
+```
+- Регистрируем в [app.module.ts](../apps/server/src/app.module.ts) рядом с `McpModule`.
+- Зависимости: `PageRepo`/`SpaceRepo` (через `DatabaseModule`), `PageService`,
+  `CollaborationGateway` (экспортировать из `CollaborationModule`),
+  `EnvironmentService`, ioredis-клиент.
+- `ScheduleModule.forRoot()` уже подключается в `TelemetryModule`; повторный вызов
+  безопасен, но лучше вынести в общий модуль или убедиться, что forRoot один раз.
+
+---
+
+## 7. Конфигурация
+
+### 7.1. Per-space (UI) — `space.settings.gitSync`
+Расширяем существующий паттерн `settings.sharing` / `settings.comments`.
+
+Сервер:
+- `UpdateSpaceDto` ([update-space.dto.ts](../apps/server/src/core/space/dto/update-space.dto.ts)):
+  добавить `@IsOptional() @IsBoolean() gitSyncEnabled?: boolean;` (+ опц.
+  `gitSyncRemote?: string`, если решим хранить remote в БД, а не только в ENV).
+- `SpaceService.updateSpace(dto, wsId)`
+  ([space.service.ts:120](../apps/server/src/core/space/services/space.service.ts#L120)):
+  обработать как `disablePublicSharing`/`allowViewerComments`.
+- `SpaceRepo`: добавить `updateGitSyncSettings(spaceId, wsId, prefKey, prefValue, trx?)`
+  по образцу `updateSharingSettings`
+  ([space.repo.ts:92](../apps/server/src/database/repos/space/space.repo.ts#L92)) —
+  jsonb-merge в `settings.gitSync.<key>`.
+- Гард: CASL `SpaceCaslAction.Manage / SpaceCaslSubject.Settings` (как в
+  [space.controller.ts:147](../apps/server/src/core/space/space.controller.ts#L147)).
+
+Клиент:
+- Тоггл в форме настроек спейса
+  ([edit-space-form.tsx](../apps/client/src/features/space/components/edit-space-form.tsx))
+  через `useUpdateSpaceMutation()` → `updateSpace({ spaceId, gitSyncEnabled })`.
+  Образец — `mcp-settings.tsx`. `readOnly` при отсутствии `Manage/Settings`.
+
+Форма `space.settings.gitSync`:
+```jsonc
+{ "gitSync": { "enabled": true, "remote": "git@…", "branch": "main" } }
+```
+
+### 7.2. Секреты/тюнинг (ENV) — `EnvironmentService`
+Движковый `settings.ts` (zod, читает `.env`) **заменяем** на чтение из gitmost
+`EnvironmentService`: `parseSettings(env)` оставляем как чистую функцию для тестов,
+но в проде собираем `Settings` из `EnvironmentService`-геттеров.
+
+Новые переменные (объявить в
+[environment.validation.ts](../apps/server/src/integrations/environment/environment.validation.ts)
+class-validator-декораторами, геттеры — в
+[environment.service.ts](../apps/server/src/integrations/environment/environment.service.ts)):
+
+| ENV | Назначение | Обяз. |
+| --- | --- | --- |
+| `GIT_SYNC_ENABLED` | глобальный мастер-выключатель | нет (default false) |
+| `GIT_SYNC_DATA_DIR` | корень vault'ов (default `<DATA_DIR>/git-sync`) | нет |
+| `GIT_SYNC_REMOTE_TEMPLATE` | шаблон remote, напр. `git@host:vault-{spaceId}.git` | нет |
+| `GIT_SYNC_SSH_KEY_PATH` / креды remote | доступ к git-remote (secret) | по ситуации |
+| `GIT_SYNC_POLL_INTERVAL_MS` | страховочный поллинг (default 15000) | нет |
+| `GIT_SYNC_DEBOUNCE_MS` | окно дебаунса событий (default 2000) | нет |
+| `GIT_SYNC_SERVICE_USER_ID` | от чьего имени писать в Docmost | да (если синк включён) |

+
+## 8. Провенанс и loop-guard
+
+### 8.1. Значение `'git-sync'`
+Сегодня `lastUpdatedSource ∈ { 'user', 'agent' }`
+([persistence.extension.ts:132-134](../apps/server/src/collaboration/extensions/persistence.extension.ts#L132-L134)).
+Добавляем `'git-sync'`:
+- `PersistenceExtension`: `context.actor === 'git-sync'` → `lastUpdatedSource = 'git-sync'`.
+- Снапшот истории для `'git-sync'` — дебаунс (как у человека), а не немедленный
+  (немедленный — только для `'agent'`,
+  [persistence.extension.ts:321](../apps/server/src/collaboration/extensions/persistence.extension.ts#L321)).
+- Для `create/move/rename/delete` через `PageService` передаём
+  `AuthProvenanceData` c `source: 'git-sync'` (тип уже используется для агента —
+  расширить допустимые значения; точную форму подтвердить на реализации).
+- Клиент: в истории
+  ([history-item.tsx:128](../apps/client/src/features/page-history/components/history-item.tsx#L128))
+  не показывать агентский бейдж/дип-линк для `'git-sync'`; добавить значение в
+  тип [page.types.ts:23-26](../apps/client/src/features/page-history/types/page.types.ts#L23-L26)
+  (опц. свой бейдж «sync»).
+
+### 8.2. Подавление петли (SPEC §10)
+На pull-стороне игнорируем страницу как «свою запись», если:
+`page.lastUpdatedSource === 'git-sync'` **И** `bodyHash(exportedBody)` совпадает
+с последним запушенным (`PushedPageRecord.bodyHash` из `push.ts`). После записи в
+Docmost сохраняем `updatedAt` ответа, чтобы поллинг-страховка не утянул свою же
+запись обратно.
+
+---
+
+## 9. Single-writer (Redis leader-lock)
+
+В кодовой базе `@Interval`-задачи (`trash-cleanup`, `telemetry`, `session-cleanup`)
+**не защищены** от мультиинстанса. Для синка добавляем явный лок.
+
+- ioredis уже есть (`RedisModule` из `@nestjs-labs/nestjs-ioredis`,
+  [app.module.ts](../apps/server/src/app.module.ts); прямой `RedisClient`
+  используется в collab-gateway).
+- Лок на спейс: `SET git-sync:lock:<spaceId> <instanceId> NX PX <ttl>`; держим
+  цикл только при успехе, продлеваем по heartbeat, освобождаем в `finally`
+  (Lua-CAS на удаление по `instanceId`, чтобы не снять чужой лок).
+- TTL > максимальной длительности цикла; на краше лок истекает сам.
+
+```ts
+// Acquire per-space leadership; returns false if another replica holds it.
+private async acquire(spaceId: string): Promise<boolean> {
+  const ok = await this.redis.set(`git-sync:lock:${spaceId}`, this.instanceId, 'PX', LOCK_TTL_MS, 'NX');
+  return ok === 'OK';
+}
+```
+
+---
+
+## 10. Планировщик и событийные триггеры
+
+- **События (основной триггер).** `PageChangeListener` подписывается на
+  `EventName.PAGE_CREATED | PAGE_UPDATED | PAGE_MOVED | PAGE_SOFT_DELETED |
+  PAGE_RESTORED | PAGE_MOVED_TO_SPACE` и job `PAGE_CONTENT_UPDATED`
+  ([event.contants.ts](../apps/server/src/common/events/event.contants.ts)).
+  Фильтр по `spaceId` (только включённые спейсы) → дебаунс (`GIT_SYNC_DEBOUNCE_MS`)
+  → ставит pull/push-цикл спейса в очередь оркестратора.
+  - Loop-guard: события от собственных записей (`source==='git-sync'` + совпавший
+    хэш) пропускаем (§8.2).
+- **Поллинг-страховка.** `@Interval(GIT_SYNC_POLL_INTERVAL_MS)` в оркестраторе:
+  по каждому включённому спейсу (под локом) — реконсиляция (`listRecentSince` +
+  `listTrash`), ловит пропущенные события и стартовую сверку после простоя
+  (SPEC §12).
+- Один цикл на спейс за раз (внутри-процессный мьютекс на `spaceId` поверх
+  Redis-лока).
+
+---
+
+## 11. Потоки данных (walkthroughs)
+
+### 11.1. Первичный клон спейса (initial clone, SPEC §12)
+1. `VaultGit.ensureRepo()` + `ensureBranch('docmost','main')` + `checkout('docmost')`.
+2. `dataSource.listSpaceTree(spaceId)` → `{ pages, complete:true }`.
+3. `readExisting({ listTracked: () => git.listTrackedFiles('*.md'), readFile })`.
+4. `computePullActions({ pages, treeComplete:true, existing })` → план.
+5. `applyPullActions(deps, actions, vaultRoot)`: на каждую страницу
+   `getPageJson` → `stabilizePageFile(content, meta)` (export→import→export
+   fixpoint, SPEC §11) → запись файла; затем `stageAll` + `commit` (трейлер
+   `docmost`) на `docmost`; `checkout('main')` + `merge('docmost')`.
+6. Зафиксировать max `updatedAt` как стартовый `T_last`; `git push` в remote.
+
+### 11.2. Docmost → FS (pull-цикл)
+Триггер: событие/поллинг → (под локом) шаги §11.1 п.1–5 инкрементально. 3-way
+merge `docmost→main` делает git: непересекающиеся правки сливаются, реальное
+пересечение → conflict-маркеры в файле. **При конфликте push этой страницы в
+Docmost блокируется** до ручного резолва (SPEC §9; фаза D).
+
+### 11.3. FS → Docmost (push-цикл)
+`runPush(deps, { dryRun })`:
+1. `git.ensureRepo` / `isMergeInProgress` (abort при merge) / `checkout('main')`.
+2. `stageAll` + `commit('local: working-tree changes')` (локально, в Docmost не шлёт).
+3. База диффа: `readRef(LAST_PUSHED_REF)` ?? `docmost`; `revParse('main')` → `pushedCommit`.
+4. `diffNameStatus(base, 'main')` → changes; префетч `metaAt(path, side)`.
+5. `computePushActions({ changes, metaAt })` → creates/updates/deletes/renamesMoves/skipped.
+6. `dryRun` → лог плана и выход (клиент НЕ создаётся).
+7. `--apply`: `makeClient(settings)` → наш `GitmostDataSource`;
+   `applyPushActions`:
+   - update → `importPageMarkdown(pageId, fullMd)` (collab-write, §3.3);
+   - create → `createPage(...)` → записать присвоенный `pageId` обратно в meta;
+   - delete → `deletePage(pageId)` (Trash);
+   - rename/move → `classifyRenameMoves` → `movePage`/`renamePage`;
+   - при пустых failures: `updateRef(LAST_PUSHED_REF, pushedCommit)` +
+     `fastForwardBranch('docmost', pushedCommit)`.
+8. Записать `bodyHash` + `updatedAt` (loop-guard, §8.2); `git push`.
+
+---
+
+## 12. Фазирование
+
+- **A. Каркас + односторонний pull (нативно).** `packages/git-sync` (вендоринг
+  §2), `GitmostDataSource` (чтение через репозитории), `GitSyncModule`, конфиг из
+  `EnvironmentService`, ручной/однократный pull-цикл на один спейс. **Гейт §13.1.**
+- **B. Push + непрерывность.** Нативная запись (§3.3), `runPush`, ветки/refs,
+  loop-guard (§8), Redis-лок (§9), `@Interval` + `PageChangeListener` (§10).
+- **C. Per-space UI.** `space.settings.gitSync` (§7.1), DTO/сервис/репо/гард,
+  тоггл на клиенте, скоуп оркестратора по включённым спейсам.
+- **D. Харднинг.** Conflict-gating (SPEC §9), удаления через Trash + git (§5),
+  стартовая реконсиляция и `move-to-space` кросс-репо, провенанс на клиенте,
+  Dockerfile `git`, полный набор тестов.
+
+---
+
+## 13. Тестирование
+
+### 13.1. Гейт идемпотентности (блокирует фазу B)
+Перенести round-trip-харнес docmost-sync (`roundtrip.ts` + `test/fixtures/corpus`)
+в тесты `packages/git-sync`, но прогонять **против схемы `editor-ext`**:
+`content (editor-ext) → convertProseMirrorToMarkdown → markdownToProseMirror →
+TiptapTransformer.toYdoc(…, tiptapExtensions) → fromYdoc → canonicalizeContent`
+должно давать `docsCanonicallyEqual === true`. Любая потеря нод/атрибутов =
+расхождение схем → чинить `docmost-schema.ts` под `editor-ext`.
+
+### 13.2. Юнит (чистая логика, переносится как есть)
+`reconcile` (planReconciliation / decideAbsenceDeletions / mass-delete guards),
+`layout` (коллизии/санитизация), `computePullActions`, `computePushActions`,
+`classifyRenameMoves`, `bodyHash`.
+
+### 13.3. Интеграция (нативный адаптер)
+`GitmostDataSource` против тестовой БД: `listSpaceTree`/`getPageJson` корректно
+маппят; `createPage`/`movePage`/`deletePage`/`importPageMarkdown` пишут через
+collab и проставляют `lastUpdatedSource='git-sync'`; loop-guard не зацикливается
+(write → poll → no-op).
+
+### 13.4. e2e (под локом)
+Полный pull→push round-trip на временном vault + временном спейсе: правка в
+Docmost доезжает в файл и наоборот; конфликт даёт маркеры и блокирует push.
+
+---
+
+## 14. Риски и открытые пункты
+
+1. **Схема-совместимость конвертера** (§3.3, §13.1) — главный риск; гейт
+   обязателен до фазы B.
+2. **`AuthProvenanceData`** — точную форму типа подтвердить; возможно, потребует
+   расширения enum источника на сервере и в истории.
+3. **Согласованность Yjs** — писать строго через `openDirectConnection`/`transact`;
+   не трогать `content`-колонку напрямую.
+4. **`position` для move** — обязателен в Docmost-move; нужен
+   `fractional-indexing-jittered` между соседями (соседей брать сортировкой
+   `position COLLATE "C"`).
+5. **`git` в рантайме** — добавить в Dockerfile.
+6. **`ScheduleModule.forRoot()`** — не задублировать `forRoot`.
+7. **Сервисный пользователь записи** (`GIT_SYNC_SERVICE_USER_ID`) — от чьего имени
+   идут create/move (влияет на `creatorId`/права); согласовать политику.
+8. **Конфликты и удаления** — фаза D строго по SPEC §8/§9 (маркеры никогда не
+   уезжают в Docmost).
+
+---
+
+## 15. Чек-лист изменений по файлам
+
+**Новый пакет**
+- `packages/git-sync/**` — движок + чистый конвертер (§2), `package.json`
+  (`@docmost/git-sync`, `workspace:*`), `tsconfig.json`.
+
+**Сервер (`apps/server/src`)**
+- `integrations/git-sync/**` — модуль, оркестратор, адаптер, листенер (§6).
+- `app.module.ts` — импорт `GitSyncModule`.
+- `collaboration/collaboration.module.ts` — экспорт `CollaborationGateway`.
+- `collaboration/extensions/persistence.extension.ts` — источник `'git-sync'` (§8.1).
+- `core/space/dto/update-space.dto.ts` — `gitSyncEnabled?` (§7.1).
+- `core/space/services/space.service.ts` — обработка флага.
+- `database/repos/space/space.repo.ts` — `updateGitSyncSettings` (§7.1).
+- `integrations/environment/environment.validation.ts` + `environment.service.ts` —
+  новые ENV (§7.2).
+- `Dockerfile` — пакет `git`.
+
+**Клиент (`apps/client/src`)**
+- `features/space/components/edit-space-form.tsx` — тоггл git-sync.
+- `features/space/types` — поле `settings.gitSync`.
+- `features/page-history/types/page.types.ts` + `components/history-item.tsx` —
+  значение `'git-sync'` в `lastUpdatedSource`.
+
+**Корень**
+- `pnpm-workspace.yaml` уже покрывает `packages/*`; `apps/server/package.json` —
+  зависимость `@docmost/git-sync: workspace:*`.

+# Мобильное приложение gitmost — исследование и план
+
+> Статус: исследовательский + проектный документ.
+> Контекст: gitmost — форк Docmost, чистое веб-приложение. Отдельного
+> мобильного (нативного/устанавливаемого) приложения **нет**.
+> Цель: определить путь к мобильным приложениям — **iOS обязательно, Android
+> как пойдёт** — с заделом на оффлайн в будущем (оффлайн сейчас не требуется).
+
+Документ фиксирует, что уже есть в коде, почему путь к мобилке предопределён
+устройством продукта, сравнивает варианты и описывает рекомендуемый план с
+привязкой к файлам.
+
+---
+
+## 1. TL;DR
+
+1. **Нативного приложения нет.** В проекте отсутствуют Capacitor, React Native,
+   Cordova и т.п. Мобильного клиента ещё не начинали.
+2. **Адаптивная веб-версия — есть, и довольно проработанная.** Веб-клиент
+   открывается с телефона как mobile-friendly сайт: сворачиваемый сайдбар-drawer,
+   отдельные мобильные компоненты (история, поиск, хлебные крошки), responsive-
+   примитивы Mantine, mobile-tuned `viewport`. Это готовый фундамент UI.
+3. **Ядро продукта — веб-редактор — нативно не воспроизвести.** TipTap 3
+   (ProseMirror) + совместное редактирование на Yjs/Hocuspocus плотно сшиты с
+   React. Production-порта Yjs под Swift/Kotlin нет. Любой реалистичный путь
+   оставляет редактор в **WebView**.
+4. **API уже готов к нативному клиенту.** Сервер принимает JWT не только из
+   cookie, но и из заголовка `Authorization: Bearer`. Есть точка входа для
+   вебсокета совместного редактирования (`POST /auth/collab-token`).
+5. **Рекомендуемый путь — Capacitor:** обернуть существующий React-SPA в
+   нативную оболочку (iOS + Android из одного кода), добавить нативные плагины
+   (push, биометрия, share, файлы). Эволюция в гибрид (нативная навигация +
+   WebView-редактор) делается потом инкрементально, без переписывания.
+6. **Оффлайн-будущее уже заложено** (Yjs + `y-indexeddb`). Детальный план —
+   в [offline-sync-plan.md](offline-sync-plan.md); мобильное приложение этот
+   план переиспользует, а не дублирует.
+7. **Главный блокер — не технический, а лицензионный.** AGPL форка несовместима
+   с условиями App Store, если зашивать веб-клиент в бинарник: DRM/usage-rules
+   Apple = «дополнительные ограничения», запрещённые AGPLv3 §10. Развязки —
+   грузить клиент с сервера (не из `.ipa`), PWA или sideload. Детали и матрица —
+   в §9; закрывать **до** кода обёртки.
+
+---
+
+## 2. Текущее состояние (как есть)
+
+### 2.1. Стек
+
+| Слой | Технологии |
+|---|---|
+| Бэкенд | NestJS 11 + Fastify, Kysely/Postgres, Redis/BullMQ. API в стиле RPC-POST (соглашение Docmost). Аутентификация — JWT. |
+| Фронт | React 18 + Vite + Mantine + TanStack Query + i18next. Обычный SPA. |
+| Ядро (редактор) | TipTap 3 (ProseMirror) + совместное редактирование на Yjs через Hocuspocus — см. [page-editor.tsx](../apps/client/src/features/editor/page-editor.tsx). |
+| Оффлайн-фундамент | `yjs` + `y-indexeddb` уже в зависимостях клиента (локальная CRDT-копия тела документа). |
+
+### 2.2. Мобильного приложения нет
+
+В `package.json` и `apps/*/package.json` нет `capacitor`, `react-native`,
+`cordova`, `expo`. Нативной оболочки в репозитории не заведено.
+
+### 2.3. Адаптивная веб-версия — есть
+
+| Что | Где |
+|---|---|
+| Адаптивная оболочка Mantine `AppShell` с `breakpoint: "sm"`, раздельные состояния `collapsed.mobile` / `collapsed.desktop` | [global-app-shell.tsx](../apps/client/src/components/layouts/global/global-app-shell.tsx) (L85–99) |
+| Отдельный мобильный сайдбар-drawer (`mobileSidebarAtom` отделён от `desktopSidebarAtom`), авто-закрытие при навигации по дереву | [sidebar-atom.ts](../apps/client/src/components/layouts/global/hooks/atoms/sidebar-atom.ts), [space-tree-row.tsx](../apps/client/src/features/page/tree/components/space-tree-row.tsx) (L147–148) |
+| Мобильная модалка истории + свой CSS | [history-modal.tsx](../apps/client/src/features/page-history/components/history-modal.tsx) (L17–19), `history-modal-mobile.tsx` |
+| Мобильный контрол поиска | [search-control.tsx](../apps/client/src/features/search/components/search-control.tsx) (L38–42) |
+| Мобильный рендер хлебных крошек через `useMediaQuery` | [breadcrumb.tsx](../apps/client/src/features/page/components/breadcrumbs/breadcrumb.tsx) (L41) |
+| Responsive-примитивы `hiddenFrom`/`visibleFrom` (~16 мест), медиа-запросы в CSS-модулях | по всему `apps/client/src` |
+| Mobile-tuned viewport (`width=device-width, user-scalable=no`) | [index.html](../apps/client/index.html) (L8) |
+
+> Важно: адаптив проверялся в мобильном **браузере**, а не в WebView нативной
+> оболочки. Перед сборкой приложения нужно прогнать UI как PWA/в WebView и
+> отловить отличия (жесты, экранная клавиатура/IME в редакторе, safe-area).
+
+### 2.4. Готовность API к нативному клиенту
+
+- **Bearer-токен уже поддержан.** JWT извлекается из cookie **или** из заголовка
+  `Authorization`: см. [jwt.strategy.ts](../apps/server/src/core/auth/strategies/jwt.strategy.ts) (L27–29).
+  Серверная сторона нативной авторизации менять не нужно.
+- **Токен сейчас не возвращается в теле логина.** [`login`](../apps/server/src/core/auth/auth.controller.ts)
+  (L55–105) кладёт JWT только в `httpOnly`-cookie ([`setAuthCookie`](../apps/server/src/core/auth/auth.controller.ts) L222–230).
+- **Точка входа вебсокета коллаборации:** [`POST /auth/collab-token`](../apps/server/src/core/auth/auth.controller.ts) (L187–193).
+- **CORS открыт без конфигурации:** [`app.enableCors()`](../apps/server/src/main.ts) (L144).
+- **OpenAPI/Swagger отсутствует** (`@nestjs/swagger` не подключён) — авто-генерации
+  типизированного клиента сейчас нет.
+
+---
+
+## 3. Почему путь к мобилке предопределён
+
+Три факта диктуют решение независимо от моды:
+
+1. **Редактор практически невозможно переписать нативно.** ProseMirror + весь
+   набор TipTap-расширений + Yjs-CRDT — это не «поле ввода». Нативного
+   production-порта Yjs под Swift/Kotlin нет (есть Rust `yrs` с биндингами, но
+   это отдельный тяжёлый проект). Переписывание ядра нативно = годы и вечное
+   расхождение с веб-версией. **Вывод: редактор остаётся в WebView.**
+2. **API уже умеет нативного клиента** (Bearer, collab-token).
+3. **Оффлайн-фундамент уже заложен** на веб-уровне (Yjs + `y-indexeddb`),
+   и он работает внутри WebView.
+
+---
+
+## 4. Три возможных пути
+
+| Путь | Суть | Плюсы | Минусы | Вердикт |
+|---|---|---|---|---|
+| **A. Полностью нативно** (Swift/Kotlin) | Переписать всё, включая редактор и CRDT-синк | Максимально нативный UX | Воспроизвести ProseMirror + расширения + Yjs; несоразмерные трудозатраты; вечное отставание от веба | ❌ Не наш случай |
+| **B. WebView-обёртка SPA (Capacitor)** | Обернуть существующий React-клиент в нативную оболочку, native-возможности — плагинами | Реюз ~100% кода (редактор, коллаборация, оффлайн); один кодовый бэйз → iOS+Android; быстро | Менее «нативно»; риск отказа App Store за «просто сайт» (4.2) — лечится нативной ценностью | ✅ Рекомендуется |
+| **C. Гибрид: нативная оболочка + WebView-редактор** | Навигация/списки/поиск/логин — нативно (React Native/Swift), экран редактирования — web в WebView | Лучший UX; путь Notion/Linear | Заметно больше работы; нужен мост JS↔native | ⚖️ Цель эволюции из B |
+
+---
+
+## 5. Рекомендуемый путь
+
+**B (Capacitor) как первый релиз, с заложенной эволюцией в C.**
+
+Почему:
+- Capacitor создан под сценарий «есть веб-приложение → хочу его в App Store с
+  нативными возможностями». Переиспользуется весь React-клиент и, главное,
+  редактор — то, что нативно не сделать.
+- Один кодовый бэйз закрывает «iOS обязательно» и «Android как пойдёт»
+  одновременно, без второй команды.
+- Адаптивная вёрстка уже есть (см. §2.3) — переверстывать под телефон с нуля
+  не нужно; работа смещается в нативную обвязку.
+- Оффлайн-будущее подготовлено (Yjs + `y-indexeddb`); см.
+  [offline-sync-plan.md](offline-sync-plan.md).
+- Когда упрётесь в UX отдельных экранов — их по одному выносят в нативную
+  оболочку, оставив редактор в WebView. То есть B → C делается инкрементально.
+
+Почему **не** чистый React Native сразу: редактор всё равно придётся держать в
+WebView (ядро web-only), но при этом теряется прямой реюз остального React-кода
+и появляется мост как обязательная сложность с первого дня — для iOS-first
+старта это лишний оверхед.
+
+> Альтернатива: если критичен максимально нативный UX с первого релиза и есть
+> ресурс — сразу путь C на React Native (Expo) с WebView только под редактор.
+> Это сознательный размен «больше работы сейчас» за «более нативное ощущение».
+
+⚠️ **Лицензионная оговорка к iOS.** Обычный Capacitor зашивает веб-билд
+`apps/client` в `.ipa` — для публикации в App Store это **нарушает AGPL**
+(см. §9). Выбор Capacitor для **Android** остаётся в силе, но на **iOS**
+веб-клиент нельзя бандлить в бинарник: либо грузить его с сервера
+(`server.url`), либо PWA. То есть рекомендация «B (Capacitor)» применима к
+Android как есть, а к iOS — только в конфигурации без зашитого AGPL.
+
+---
+
+## 6. Что доработать на бэкенде
+
+Немного, но конкретно:
+
+1. **Выдача токена в теле ответа для нативного хранения.** Сейчас логин кладёт
+   JWT только в `httpOnly`-cookie и не возвращает его в body. На мобиле
+   `httpOnly`-cookie между разными origin (`capacitor://localhost` ↔ API) — боль
+   с SameSite/CORS. Чище: мобильный логин-флоу, возвращающий JWT в ответе, чтобы
+   хранить его в Keychain/Keystore и слать как `Authorization: Bearer`. Сервер
+   уже принимает Bearer — менять надо только **выдачу**.
+   Файлы: [auth.controller.ts](../apps/server/src/core/auth/auth.controller.ts).
+2. **CORS.** Сейчас [`app.enableCors()`](../apps/server/src/main.ts) (L144) без
+   конфигурации. Под мобильные origin'ы и для безопасности задать явный whitelist.
+3. **Push-уведомления.** Модуль `notification` уже есть — добавить регистрацию
+   device-token и интеграцию **APNs** (iOS) / **FCM** (Android).
+4. **Опционально — OpenAPI/Swagger.** Сейчас спецификации нет; добавить
+   `@nestjs/swagger` дёшево и сильно ускорит мобильную разработку
+   (типизированный клиент).
+
+---
+
+## 7. Android-специфика
+
+На пути Capacitor Android едет почти бесплатно (`npx cap add android` из того же
+веб-билда), но есть нюансы:
+
+- **Движок в плюс.** Android System WebView (Chromium) обновляется через Play
+  Store независимо от ОС и обычно свежее iOS WKWebView. Более рискованный движок
+  по совместимости — это iOS, а не Android.
+- **Фрагментация.** Дешёвые/старые устройства с малой памятью и устаревшим
+  WebView; стек тяжёлый (ProseMirror + Yjs + mermaid + katex + excalidraw) —
+  тестировать на бюджетных аппаратах.
+- **Обвязка под Android:** аппаратная/жестовая кнопка «Назад» (навигация внутри
+  приложения, а не выход), **FCM** для push, Android App Links (вместо iOS
+  Universal Links), подписание и Play Console.
+- **Главный риск именно для Android — ввод текста в ProseMirror на Gboard/IME.**
+  Историческая боль `contenteditable` на Android (прыжки курсора, дубли символов
+  при композиции). Стало лучше, но **проверять в первую очередь и рано**.
+- **Магазин.** Google Play лояльнее к webview-обёрткам, чем App Store; риск
+  «отклонят как просто сайт» для Play практически неактуален.
+
+---
+
+## 8. iOS-специфика
+
+- **WKWebView** на движке WebKit жёстко привязан к версии ОС — это более
+  рискованный по совместимости движок (тестировать прежде всего его).
+- **App Store guideline 4.2 (minimum functionality).** Чистая webview-обёртка
+  рискует отклонением «это просто сайт». Лечится реальной нативной ценностью:
+  push, share-extension, биометрический разблок, оффлайн-кэш — всё это Capacitor
+  даёт плагинами.
+- **safe-area** под «чёлку»/системные панели, поведение экранной клавиатуры в
+  редакторе.
+
+---
+
+## 9. Лицензионный блокер: AGPL ↔ App Store (iOS)
+
+> Это не инженерная, а **лицензионная** задача — закрывать её надо **до** кода
+> обёртки, иначе можно сделать приложение, которое некуда легально опубликовать.
+> Ниже — инженерно-лицензионный разбор, **не** юридическая консультация; финально
+> подтверждать у того, кто разбирается в лицензиях.
+
+### 9.1. Суть конфликта
+
+gitmost — форк Docmost под **AGPL-3.0** (константа форка: «100% open, AGPL-only»).
+Две вещи несовместимы:
+
+- **AGPLv3 §10** (последний абзац) запрещает накладывать на получателя кода
+  **любые дополнительные ограничения** сверх самой лицензии.
+- **Стандартный EULA App Store** ровно их и накладывает: **FairPlay/DRM**,
+  привязка установки к Apple ID с лимитом устройств (**usage rules**), запрет
+  свободного перераспространения бинарника.
+
+Приняв условия Apple, чтобы попасть в App Store, вы нарушаете AGPL кода, который
+раздаёте.
+
+### 9.2. Почему это бьёт именно по форку
+
+Запрет «дополнительных ограничений» связывает **лицензиатов, но не самого
+правообладателя**: владелец 100% копирайта может опубликовать свой код в App Store.
+Но в gitmost бóльшая часть копирайта принадлежит **upstream-Docmost** и
+контрибьюторам — вы выступаете дистрибьютором *чужого* AGPL-кода и не можете
+единолично добавить App-Store-исключение.
+
+Прецеденты: **VLC** (удалён из App Store в 2011 по жалобе на конфликт GPL с
+условиями стора; вернулся только после перелицензирования и согласия
+правообладателей), **GNU Go** — снят по той же причине. Это не теоретический риск.
+
+### 9.3. Ключевой принцип развязки: лицензия смотрит на `.ipa`, а не на устройство
+
+Определяющее — **что раздаёт сам Apple** (`.ipa` под FairPlay) и **кто раздаёт
+AGPL-байты**, а не то, окажутся ли они в итоге на устройстве:
+
+- AGPL **внутри `.ipa`** → получен под ограничениями Apple → **нарушение**.
+- AGPL **скачан с вашего сервера** → получен от вас под AGPL (исходники открыты,
+  §13 выполнен) → ограничения Apple на него **не** накладываются, даже если бандл
+  кэшируется в песочнице приложения.
+
+Следствие: **офлайн на iOS легально достижим** — если кэшированный бандл пришёл с
+вашего сервера, а не из `.ipa`. Ограничение тут не лицензионное, а в **ревью
+Apple** (см. §9.5).
+
+### 9.4. Варианты «грузить веб-клиент с сервера»
+
+**A. WebView навигируется на хостед-клиент (`server.url`).** Capacitor умеет
+`server: { url: 'https://app.example.com' }` — оболочка грузит WebView с удалённого
+URL, мост и нативные плагины по-прежнему инжектятся. В `.ipa` — ноль AGPL.
+
+- Плюс: лицензионно самый чистый; **origin = ваш домен**, поэтому cookie/CORS
+  работают как в браузере (боль `capacitor://localhost` ↔ API из §6 исчезает —
+  токен в body/Keychain может и не понадобиться).
+- Минус: холодный старт требует сети; сервер лёг → приложение кирпич; офлайна по
+  умолчанию нет.
+
+**B. OTA: пустой шелл скачивает и кэширует бандл.** Шелл при первом запуске тянет
+JS-бандл с вашего сервера и кэширует как веб-ассеты (механизм Cordova/CodePush).
+Open-source self-host-вариант — `@capgo/capacitor-updater` (важно для AGPL-проекта:
+без привязки к проприетарному Appflow).
+
+- Плюс: **даёт офлайн** — кэш AGPL легален, т.к. распространён вами, а не Apple.
+- Минус: упирается в политику Apple по hot-update (§9.5).
+
+**Не-обходы (мифы):** «никто не засудит» — это нарушение, а не обход; «LGPL-нуть
+обёртку» — не помогает (проблема в AGPL-веб-клиенте, а не в обёртке); «mere
+aggregation» — не катит: зашитый бандл это комбинированное распространяемое
+произведение, а не простая агрегация.
+
+### 9.5. Гейты Apple
+
+| # | Guideline | Суть | Влияние |
+|---|---|---|---|
+| 1 | **2.5.2** (исполняемый код) | Скачивать/исполнять **нативный** код нельзя, **но** есть исключение для скриптов, исполняемых встроенным WebKit/JavascriptCore, если они не меняют назначение приложения | Загрузка веб-клиента в `WKWebView` под исключение попадает: вариант A — чистый, B — терпимый, но с границами |
+| 2 | **4.2** (minimum functionality) | Чистый WebView-«просто сайт» рискует отклонением | Лечится нативной ценностью в оболочке (push/APNs, биометрия, share, файлы — ваш нативный код, не AGPL) |
+| 3 | конфликт двух гейтов | «Лицензионно чистый» вариант (пустой шелл качает всё) — самый рискованный для ревью; «безопасный для ревью» (зашить веб-билд в `.ipa`) — лицензионное нарушение | **Совместить (офлайн) + (чистая AGPL) + (низкий риск ревью) в одной конфигурации нельзя — выбираете любые два** |
+
+Безопасность: раз исполняете удалённый код — только HTTPS, желательно cert-pinning
+(подмена сервера = произвольный JS в WebView пользователя).
+
+### 9.6. Итоговая матрица распространения iOS
+
+| Конфигурация | AGPL-чистота | Офлайн | Риск ревью Apple |
+|---|---|---|---|
+| A. `server.url` на хостед-клиент | ✅ чистая | ❌ нет | средний (4.2, лечится плагинами) |
+| B. OTA пустой шелл + кэш бандла | ✅ чистая | ✅ есть | выше (2.5.2 + 4.2) |
+| Зашить веб-билд в `.ipa` (обычный Capacitor) | ❌ нарушение | ✅ | низкий |
+| **PWA** | ✅ чистая | ✅ | App Store не нужен |
+| Sideload / EU DMA-маркетплейсы (iOS 17.4+) | ✅ чистая | ✅ | вне App Store; **только ЕС** |
+
+**Вывод:** для iOS **PWA** — самое дешёвое решение, закрывающее всё сразу. Если
+присутствие именно в App Store критично — **вариант A** (`server.url` + нативные
+плагины под 4.2) легальный и реалистичный ценой «онлайн для холодного старта».
+Офлайн в App Store (вариант B) технически и лицензионно возможен, но это
+максимальный риск на ревью — закладывать только если офлайн на iOS обязателен.
+Совместить «App Store + зашитый офлайн AGPL» легально нельзя, пока копирайт не ваш.
+
+---
+
+## 10. Оффлайн в будущем
+
+Оффлайн сейчас не требуется, но позиция хорошая:
+
+- Тело документа уже редактируется через Yjs (CRDT) + `y-indexeddb` — локальная
+  копия и автослияние правок работают, в том числе в WebView.
+- «Полностью онлайн» — это всё вокруг тела (навигация, заголовки, комментарии,
+  CRUD, вложения, авторизация). Их оффлайн-синхронизация описана отдельным
+  планом с этапами M0…M4 — см. [offline-sync-plan.md](offline-sync-plan.md).
+- Мобильное приложение **переиспользует** этот план, а не строит оффлайн заново.
+  Нюанс Android: System WebView под нехваткой места может чистить хранилище →
+  для оффлайна, возможно, понадобится дублировать критичные данные в нативное
+  хранилище, чтобы локальные копии не вычищались.
+
+---
+
+## 11. Открытые вопросы (зафиксировать до старта)
+
+- **Q1.** Путь: Capacitor (B) с эволюцией в гибрид, или сразу React Native (C)?
+  Рекомендация — B.
+- **Q2.** Мобильная авторизация: отдельный логин-флоу с токеном в body + Keychain/
+  Keystore + Bearer (рекомендуется) или попытка работать через cookie в WebView?
+- **Q3.** Push: APNs + FCM сразу или iOS-first?
+- **Q4.** Подключать ли OpenAPI/Swagger для генерации мобильного клиента?
+- **Q5.** Когда включать оффлайн (M0…M4 из offline-sync-plan.md) относительно
+  первого мобильного релиза?
+- **Q6.** iOS-дистрибуция при AGPL (§9): App Store через `server.url`
+  (онлайн-клиент, без зашитого AGPL), PWA или sideload/EU-маркетплейсы? Этот
+  лицензионный путь нужно подтвердить **до** кода обёртки. Рекомендация — PWA для
+  iOS, Capacitor для Android.
+
+---
+
+## 12. Чеклист первого шага (бутстрап Capacitor, iOS-first)
+
+- [ ] **Закрыть лицензионный путь iOS (§9) ДО кода обёртки:** выбрать
+      `server.url` / PWA / sideload и подтвердить у разбирающегося в лицензиях.
+- [ ] **Не бандлить AGPL-веб-клиент в iOS `.ipa`** (DRM/usage-rules App Store ⟂
+      AGPLv3 §10) — на iOS грузить клиент с сервера или идти через PWA.
+- [ ] Прогнать существующий адаптивный UI как PWA/в WebView, отловить отличия
+      (жесты, IME в редакторе, safe-area).
+- [ ] Добавить Capacitor в монорепо, нацелить на веб-билд `apps/client`
+      (Android — зашитый билд; iOS — `server.url`/PWA без зашитого AGPL, см. §9).
+- [ ] `npx cap add ios` (Android — `npx cap add android`, когда будет готова обвязка).
+- [ ] Бэкенд: мобильный логин-флоу с токеном в body; хранить токен в Keychain/
+      Keystore; слать `Authorization: Bearer`.
+- [ ] Бэкенд: явный CORS-whitelist под мобильные origin'ы.
+- [ ] Native-плагины под App Store 4.2: push, биометрия, share, файлы.
+- [ ] Push: APNs (iOS); FCM добавить вместе с Android.
+- [ ] Проверить вебсокет коллаборации из WebView (`/auth/collab-token` + Hocuspocus).
+- [ ] (Опционально) Подключить `@nestjs/swagger`.

+# Множественные курсоры (multi-cursor editing) — анализ и подходы
+
+> Статус: **черновик / обсуждение**. Код не пишется; цель этого документа — зафиксировать архитектурный вердикт, развилку подходов и рекомендацию.
+>
+> Важное уточнение термина: речь про **несколько собственных курсоров одного пользователя в одном документе** (как в VS Code: `Alt+Click` добавить курсор, `Ctrl/Cmd+D` — следующее вхождение, `Ctrl/Cmd+Shift+L` — все вхождения), чтобы править несколько мест одновременно. **Не** про collaborative-курсоры соавторов — те в проекте уже работают (`CollaborationCaret` + Hocuspocus awareness).
+>
+> Зафиксированные выводы (см. разделы ниже):
+> - Полноценный VS Code-style multi-cursor нельзя «включить флагом»: движок редактора (ProseMirror) хранит в состоянии **ровно одно выделение**, в отличие от Monaco/CodeMirror с массивом selections. Готового production-пакета в экосистеме Tiptap/ProseMirror нет.
+> - ~80% пользовательской ценности даёт ограниченный MVP («выделить все вхождения + одновременный ввод»), который опирается на **уже работающий** в проекте механизм `replaceAll` из расширения `SearchAndReplace`.
+> - Рекомендация: реализовать MVP (Вариант A); полноценный набор (Вариант B) — отдельный большой эпик, имеет смысл браться только если MVP окажется недостаточно.
+
+## 0. О чём речь (и о чём НЕ речь)
+
+**Что хочется** — несколько кареток в одном документе; набранный текст и `Backspace`/`Delete` применяются ко всем позициям одновременно; одно `Cmd/Ctrl+Z` откатывает всю мульти-правку целиком. Сценарии из VS Code:
+
+| Действие | Горячая клавиша | Суть |
+| --- | --- | --- |
+| Добавить курсор | `Alt+Click` | Курсор в произвольной точке клика |
+| Добавить курсор строкой выше/ниже | `Ctrl/Cmd+Alt+↑/↓` | Копия курсора на соседней строке |
+| Выделить следующее вхождение | `Ctrl/Cmd+D` | Добавить к набору следующее вхождение слова |
+| Выделить все вхождения | `Ctrl/Cmd+Shift+L` | Все вхождения сразу |
+| Колонковое/блочное выделение | `Alt+drag` | Прямоугольник курсоров по строкам |
+
+**О чём НЕ речь** — collaborative-курсоры (видеть, где сейчас находится другой соавтор). Это в Gitmost уже есть и работает отдельно: `CollaborationCaret` в [extensions.ts](apps/client/src/features/editor/extensions/extensions.ts) подключается через `collabExtensions(...)`, а сервер Hocuspocus по умолчанию форвардит awareness. Этот документ её не касается.
+
+## 1. Архитектурный вердикт: почему это не «включить флаг»
+
+Редактор Gitmost — **Tiptap поверх ProseMirror** (`@tiptap/core` 3.20.4, `@tiptap/pm` 3.20.4). Принципиальное отличие от VS Code: Monaco/CodeMirror хранит **массив selections**, а ProseMirror хранит в `EditorState` **ровно один** `Selection`:
+
+```
+EditorState = { doc, selection: Selection /* единственное */, storedMarks, ... }
+```
+
+На этой единственной selection завязано в ProseMirror почти всё:
+- команды ввода (`insertText`, `insertContent`) работают с текущей `selection`;
+- обработчики `handleTextInput`, `handleKeyDown`, `handlePaste`, `handleDrop` получают одно выделение;
+- история (undo/redo) оперирует transactions с одним выделением;
+- **критично для нас** — синхронизация через y-prosemirror тоже опирается на единственную selection (свою «awareness-selection» отдельно, но не на локальный массив).
+
+Доказательства из первоисточников:
+- Tiptap issue [ueberdosis/tiptap#3370](https://github.com/ueberdosis/tiptap/issues/3370) «Multiple cursors per user» — открыт, официальной поддержки нет.
+- Ответ **marijnh** (автор ProseMirror) на [discuss.prosemirror.net](https://discuss.prosemirror.net/t/multi-cursor-editing-in-prosemirror-or-tiptap/8397): готовой реализации нет, но путь обозначен — **«кастомный подкласс `Selection`, по аналогии с `CellSelection` из `prosemirror-tables`, который умеет содержать несколько отдельных диапазонов»**.
+- Production-готового пакета multi-cursor для Tiptap/ProseMirror в npm **нет** — пилить с нуля.
+
+**Вывод:** полноценный multi-cursor — это R&D-проект против устройства движка, а не настройка. Но самый ценный сценарий («поправить повторяющиеся одинаковые куски сразу в нескольких местах») реализуем дёшево, потому что массовая правка в одном transaction у нас уже написана.
+
+## 2. Что уже есть в коде и переиспользуемо
+
+В проекте уже есть расширение [SearchAndReplace](packages/editor-ext/src/lib/search-and-replace/search-and-replace.ts) (в `editor-ext`, подключено и в клиентском редакторе). Это почти готовый фундамент для главного сценария multi-cursor:
+
+- [search-and-replace.ts:100-174](packages/editor-ext/src/lib/search-and-replace/search-and-replace.ts#L100-L174) — `processSearches` уже находит **все** вхождения терма и возвращает массив `results: Range[]` (диапазоны `from`/`to`).
+- [search-and-replace.ts:157-168](packages/editor-ext/src/lib/search-and-replace/search-and-replace.ts#L157-L168) — уже рисует `Decoration.inline` для **всех** совпадений одновременно (это переиспользуется для подсветки «активных» курсоров).
+- [search-and-replace.ts:213-246](packages/editor-ext/src/lib/search-and-replace/search-and-replace.ts#L213-L246) — `replaceAll` уже выполняет **массовую правку в одном transaction**, идя **с конца**, чтобы корректно учитывать сдвиг позиций после каждой вставки/удаления. Это ровно та механика, что нужна для одновременного ввода в несколько курсоров.
+
+```ts
+// search-and-replace.ts:213-246 — готовый эталон массового transaction
+const replaceAll = (replaceTerm, results, { tr, dispatch }) => {
+  // Process replacements in reverse order to avoid position shifting issues
+  for (let i = resultsCopy.length - 1; i >= 0; i -= 1) {
+    const { from, to } = resultsCopy[i];
+    // ... собрать marks, удалить старый текст, вставить новый
+    tr.delete(from, to);
+    if (replaceTerm) tr.insert(from, tr.doc.type.schema.text(replaceTerm, marks));
+  }
+  dispatch(tr); // одна транзакция → одна запись в истории (один undo)
+};
+```
+
+То есть самая хитрая часть multi-cursor — применить правку к N позициям за один `tr` с корректным маппингом — у нас **уже работает** в `replaceAll`.
+
+Дополнительно в клиенте уже есть инфраструктура для горячих клавиш: в [page-editor.tsx:258-280](apps/client/src/features/editor/page-editor.tsx#L258-L280) есть блок `handleDOMEvents.keydown`, и используется утилита `platformModifierKey` (Cmd на macOS, Ctrl на других ОС — ровно то, что нужно для совместимых с VS Code шорткатов).
+
+## 3. Развилка: три подхода
+
+### 3.1 Вариант A — MVP: «выделить все вхождения + одновременный ввод» (рекомендация)
+
+Реализует главный сценарий из VS Code:
+- `Ctrl/Cmd+Shift+L` — берём слово под курсором (или текущее выделение), находим все вхождения, превращаем их в «активные курсоры»;
+- `Ctrl/Cmd+D` — добавить следующее вхождение к набору;
+- дальнейший ввод текста и `Backspace`/`Delete` применяются ко всем позициям одновременно через один transaction (копия механики `replaceAll`);
+- `Esc` — выйти из multi-cursor (один курсор).
+
+**Что переиспользуется:** массив `results` и логика массового `tr` берутся из [SearchAndReplace](packages/editor-ext/src/lib/search-and-replace/search-and-replace.ts) почти готовыми.
+
+**Визуальные каретки:** через `Decoration.widget(pos, () => cursorDomElement)` — ProseMirror умеет «из коробки»; для диапазонов — `Decoration.inline`.
+
+**Объём работы:** средний. Один новый Tiptap-extension в `packages/editor-ext/src/lib/multi-cursor/` + wiring в клиентском редакторе + горячие клавиши + CSS + юнит-тесты.
+
+**Риски:** средние и ограниченные. Скоуп узкий (только текстовые вхождения), сценарии предсказуемые, тестируются конечным числом кейсов.
+
+### 3.2 Вариант B — полноценный multi-cursor (как Monaco)
+
+Полный набор из §0: `Alt+Click` (произвольная точка), `Alt+drag` (колонковое выделение), `Ctrl/Cmd+Alt+↑/↓` (курсор на соседней строке), а также произвольный набор **несвязанных** курсоров (не по вхождениям).
+
+**Путь:** кастомный `MultiSelection extends Selection` (по подсказке мейнтейнера ProseMirror, по образцу `CellSelection` из `prosemirror-tables`), плюс **полная маршрутизация ввода**:
+- перехват `handleTextInput`, `handleKeyDown` (Backspace/Delete/стрелки/Enter/Home/End), `handlePaste`, `handleDrop`;
+- построение одного мульти-position transaction для каждого события;
+- визуальный рендер нескольких кареток и диапазонов;
+- undo-группировка (одно `Cmd/Ctrl+Z` откатывает все позиции разом);
+- перемапливание позиций курсоров при **любых** изменениях документа, включая remote Yjs-правки.
+
+**Объём работы:** очень большой (многие недели). Готового референса в экосистеме нет — это самостоятельный R&D с отладкой на реальном контенте.
+
+**Риски:** высокие — см. риск-карту в §4 (IME/composition, конфликты со сложными нодами вроде таблиц и code-блоков, взаимодействие с коллаборацией).
+
+### 3.3 Вариант C — эмуляция через коллаборацию (отбрасываем)
+
+Идея из Tiptap#3370: «проигрывать правки через отдельного pseudo-user через collaborative-слой». **Не берём:** ломает provenance правок (в проекте есть бейдж авторства «AI agent» в истории страницы, migration `20260616T130000-agent-provenance` — такой хак его загрязнит и запутает), портит историю undo, концептуально криво и хрупко.
+
+### Сводка
+
+| | Вариант A (MVP) | Вариант B (full) | Вариант C |
+| --- | --- | --- | --- |
+| Сценарии | «все вхождения», «+следующее вхождение» | полный набор VS Code | — |
+| База | готовый `replaceAll` | кастомный `Selection` с нуля | collaborative-слой |
+| Объём | средний | очень большой | — |
+| Риск | средний (ограниченный) | высокий | высокий |
+| Рекомендация | **да** | только если A мало | нет |
+
+## 4. Риск-карта
+
+Для обоих вариантов, но в варианте B каждый пункт — сильно жёстче.
+
+| Зона | Суть | Где больнее |
+| --- | --- | --- |
+| **Undo/redo** | Мульти-правка должна быть **одной** записью истории (одно `Cmd/Ctrl+Z` откатывает все позиции). Группировка через мету истории, см. как `replaceAll` делает один `dispatch(tr)`. | B |
+| **Коллаборация (Yjs)** | Пока активны ваши курсоры, может прилететь remote-правка — позиции курсоров надо перемапливать через `tr.mapping.map(pos)`. Один локальный `tr` с правками в N местах Yjs переварит нормально (это несколько правок в одном Update). | B |
+| **IME / dead keys** | Ввод через composition (буквы с акцентами, CJK) одновременно в несколько курсоров — крайне хрупко; для MVP (Вариант A) проще: на время composition можно схлопывать к одному курсору. | B |
+| **Schema / сложные узлы** | Курсор внутри code-блока + курсор в заголовке: одна и та же вставка может нарушить schema одного узла, но не другого. Нужно gracefully skip конфликтующие курсоры (не ронять весь `tr`). | B (A — почти не касается, т.к. вхождения — текстовые) |
+| **Таблицы / callouts** | `CellSelection`-подобная логика внутри таблиц — отдельная вселенная; в MVP курсоры в таблицах можно просто не поддерживать (как и в `replaceAll`). | B |
+| **Производительность** | Очень много курсоров → большой `DecorationSet` и длинный `tr`. Практически редко > нескольких десятков, но заложить верхнюю границу. | общий |
+
+## 5. Рекомендация
+
+**Брать Вариант A.** Он закрывает главный use-case («быстро поправить повторяющиеся одинаковые куски сразу в нескольких местах»), опирается на **уже работающий** `replaceAll`-механизм, и риск ограничен. Вариант B имеет смысл отдельным эпиком — только если A окажется недостаточно и будет устойчивый спрос на произвольные курсоры; тогда начинать стоит с прототипа кастомного `MultiSelection`, чтобы доказать жизнеспособность на сложных узлах до полной реализации.
+
+Сознательные границы MVP (Вариант A) — см. §6.7.
+
+## 6. План реализации Варианта A (MVP) — по шагам
+
+### 6.1. Новый extension
+
+Создать `packages/editor-ext/src/lib/multi-cursor/multi-cursor.ts` — Tiptap `Extension`:
+- плагин (ProseMirror `Plugin`) со state = `{ cursors: {from: number, to: number}[] }` и `DecorationSet` (виджеты-каретки для точечных курсоров + `Decoration.inline` для диапазонов);
+- команды:
+  - `selectAllOccurrences` — берёт слово под курсором (или текущее выделение), находит все вхождения (можно вынести общую с search-and-replace логику поиска в утилиту, чтобы не дублировать `processSearches`), заполняет `cursors`;
+  - `addNextOccurrence` (`Ctrl/Cmd+D`) — добавляет следующее вхождение к `cursors`;
+  - `exitMultiCursor` — очищает `cursors` (также вешается на `Esc`);
+- обработчики в `props`:
+  - `handleTextInput(view, from, to, text)` — если `cursors` непустой, строит один `tr`, вставляя `text` в каждую позицию **с конца** (копия механики из [search-and-replace.ts:213-246](packages/editor-ext/src/lib/search-and-replace/search-and-replace.ts#L213-L246));
+  - `handleKeyDown` — `Backspace`/`Delete` аналогично (удаление символа перед/после каждой позиции);
+  - игнорировать/схлопнуть multi-cursor при начале composition (IME) — см. §4.
+
+### 6.2. Маппинг позиций при изменениях документа
+
+В `state.apply` плагина — при любом `docChanged` перемапливать все позиции через `tr.mapping.map(pos)` и удалять «схлопнувшиеся» (`from === to` после маппинга — это нормально для каретки). Это покрывает и собственные правки, и **remote Yjs-правки** (y-prosemirror применяет их как обычные transactions — маппинг работает одинаково).
+
+### 6.3. Горячие клавиши
+
+Добавить в существующий блок [page-editor.tsx:258-280](apps/client/src/features/editor/page-editor.tsx#L258-L280) (там уже есть `platformModifierKey`):
+- `platformModifierKey + Shift + KeyL` → `selectAllOccurrences`;
+- `platformModifierKey + KeyD` → `addNextOccurrence`;
+- `Escape` → `exitMultiCursor`.
+
+⚠️ Проверить конфликт `Ctrl/Cmd+D` с браузерным «добавить в закладки» (предотвратить через `event.preventDefault()`) и с любыми существующими биндингами редактора.
+
+### 6.4. Регистрация
+
+- экспортировать расширение из `packages/editor-ext/src/lib/multi-cursor/index.ts` и добавить в `packages/editor-ext/src/index.ts`;
+- включить в `mainExtensions` в [extensions.ts](apps/client/src/features/editor/extensions/extensions.ts) (оно не зависит от коллаборации, поэтому идёт в основной набор, доступный и в обычном, и в коллаборативном редакторе).
+
+### 6.5. CSS
+
+Рядом с [collaboration.css](apps/client/src/features/editor/styles/collaboration.css) (и подключением через `styles/index.css`) — стили для классов вроде `.multi-cursor__caret` и `.multi-cursor__label`. Визуально отличать от collaborative-кареток (например, другим стилем/цветом), чтобы не путать свои мульти-курсоры с курсорами соавторов.
+
+### 6.6. Тесты
+
+Unit-тесты в `packages/editor-ext` (по образцу существующих там тестов) на:
+- корректность массового `tr` (ввод/удаление в N позициях, проверка результирующего документа);
+- маппинг позиций после локальной правки и после имитированной remote-правки;
+- граничные случаи: курсоры на границах узлов, схлопывание, пустой набор.
+
+### 6.7. Скоуп v1 / что сознательно НЕ входит
+
+Чтобы держать риск в пределах, в MVP **не делаем** (явно фиксируем как out-of-scope):
+- `Alt+Click` (произвольная точка) и `Alt+drag` (колонковое выделение) — это путь в Вариант B;
+- `Ctrl/Cmd+Alt+↑/↓` (курсор на соседней строке) — то же;
+- курсоры внутри таблиц, code-блоков и callouts — только обычный текст (как в `replaceAll`);
+- одновременный ввод через IME в несколько позиций (на время composition схлопываем к одному курсору);
+- курсоры, затрагивающие разные schema-узлы одновременно (если вставка нарушает schema в одной из позиций — пропускаем эту позицию, не роняем весь `tr`).
+
+Эти границы — кандидаты на v2 / переход к Варианту B.
+
+## 7. Открытые вопросы
+
+1. **Выделение диапазонов vs точечные курсоры.** В VS Code `Ctrl/Cmd+Shift+L` выделяет целые слова (диапазоны). Делаем ли мы в MVP то же (диапазоны + одновременная замена всего слова), или только точечные каретки после конца слова? Рекомендация: диапазоны — это даёт «переименовать все эти слова сразу», что и есть главная ценность.
+2. **Общая утилита поиска.** Вынести `processSearches` из search-and-replace в общую утилиту, чтобы не дублировать, или оставить независимую реализацию в multi-cursor? Рекомендация: вынести общую часть (поиск всех вхождений слова по документу), оба расширения используют её.
+3. **Граница производительности.** Ввести ли хард-кап на число одновременных курсоров (например, 100) с предупреждением пользователю? Рекомендация: да, как страховка.

+# Offline-режим и синхронизация правок в gitmost
+
+> Статус: проектный документ, готов к реализации.
+> Контекст: gitmost — форк Docmost. Сейчас приложение полностью онлайн.
+> Цель: дать возможность работать оффлайн (читать и редактировать) и
+> синхронизироваться при возврате сети.
+
+Документ описывает текущее устройство, целевую архитектуру и пошаговый план
+реализации с привязкой к конкретным файлам. Его можно взять и реализовывать
+по этапам M0…M4.
+
+---
+
+## 1. TL;DR
+
+1. **Половина оффлайна уже встроена.** Тело страницы редактируется через Yjs
+   (CRDT) + Hocuspocus, а на клиенте уже подключён `y-indexeddb`. Правки тела
+   *уже открытой* страницы переживают потерю сети и **сами мёржатся** при
+   реконнекте — без конфликтов.
+2. **«Полностью онлайн» — это всё вокруг тела документа:** загрузка самого
+   приложения, навигация (дерево/список), заголовки страниц, комментарии,
+   создание/перемещение/удаление страниц, вложения, авторизация.
+3. **Оффлайн делится на два контура с разными механизмами синхронизации:**
+   - **Контур A — тело документа:** CRDT (Yjs). Почти готов, нужно укрепить.
+   - **Контур B — структурные данные (REST):** не CRDT. Нужен паттерн
+     *локальный кэш + outbox (очередь мутаций) + правила разрешения конфликтов*.
+4. **PWA — обязательный фундамент, но это два слоя:**
+   - *Installability* (manifest + meta-теги) — **уже есть** в gitmost
+     (унаследовано от Docmost). Forkmost добавляет только косметику.
+   - *Service worker* (кэш app-shell, запуск без сети) — **нет нигде**, это и
+     есть реальная невыполненная часть. Без него установленное приложение без
+     сети покажет пустой экран.
+
+---
+
+## 2. Текущее состояние (как есть)
+
+### 2.1. Контур A: тело документа — CRDT, почти готово
+
+| Где | Что делает |
+|---|---|
+| [page-editor.tsx](../apps/client/src/features/editor/page-editor.tsx) (L131–206) | На каждую страницу создаётся `Y.Doc`, к нему цепляются `IndexeddbPersistence("page.<id>")` (локальная копия) **и** `HocuspocusProvider` (WS-синк). |
+| [persistence.extension.ts](../apps/server/src/collaboration/extensions/persistence.extension.ts) | Сервер в `onStoreDocument` хранит в Postgres бинарный `ydoc` (Y state update) **плюс** отрендеренный tiptap-JSON `content` + `textContent`. В `onLoadDocument` поднимает `ydoc` обратно. |
+| [collaboration/extensions/redis-sync/](../apps/server/src/collaboration/extensions/redis-sync/) | Redis-синк для горизонтального масштабирования инстансов. |
+
+Почему это и есть оффлайн-редактирование: Yjs — CRDT, апдейты коммутативны.
+Пока клиент оффлайн, изменения копятся в `Y.Doc` и в IndexedDB; при возврате
+сети `HocuspocusProvider` обменивается state-векторами и **детерминированно
+сливает** правки. Конфликтов «кто кого перезаписал» в теле документа нет.
+
+### 2.2. Контур B: структурные данные — обычный REST, оффлайн недоступен
+
+| Сущность | Где | Механизм |
+|---|---|---|
+| Заголовок страницы | [title-editor.tsx](../apps/client/src/features/editor/title-editor.tsx) (L48–152) | REST `/pages/update`, дебаунс 500 мс. **НЕ Yjs.** |
+| CRUD страниц, move, restore | [page-service.ts](../apps/client/src/features/page/services/page-service.ts) | REST `/pages/*` |
+| Комментарии | [comment-service.ts](../apps/client/src/features/comment/services/comment-service.ts) | REST `/comments/*` |
+| Watchers, favorites, labels, дерево, поиск | соответствующие `features/*/services` | REST |
+
+Состояние клиента:
+- React Query: [main.tsx](../apps/client/src/main.tsx) (L26), `queryClient`
+  экспортируется, `retry:false`, `staleTime: 5 мин`. **Персистентности на диск
+  нет.** При перезагрузке без сети читать нечего.
+- HTTP: [api-client.ts](../apps/client/src/lib/api-client.ts) — axios `/api`,
+  `withCredentials`. На `401` → `redirectToLogin()`. **Важно для оффлайна:**
+  редирект на логин при сетевой ошибке недопустим (см. M4).
+
+### 2.3. PWA: что уже есть
+
+- [manifest.json](../apps/client/public/manifest.json) — присутствует
+  (`display: standalone`, иконки).
+- [index.html](../apps/client/index.html) (L9–16) — PWA meta-теги
+  (`apple-mobile-web-app-capable`, `mobile-web-app-capable`, `theme-color` и т.д.).
+- **Service worker отсутствует.** Нет `vite-plugin-pwa`, Workbox, precache.
+
+> Вывод по Forkmost (`Vito0912/forkmost`): их «PWA-наработки» — это только
+> манифест и meta-теги (closing issue Docmost #328 про *устанавливаемость*).
+> Service worker / оффлайн-кэша там нет. В gitmost installability уже есть,
+> поэтому из Forkmost переносить нечего, кроме косметики.
+
+### 2.4. Полезные примитивы, которые уже есть в проекте
+
+- **Fractional indexing для позиций страниц:**
+  [page.service.ts](../apps/server/src/core/page/services/page.service.ts)
+  использует `generateJitteredKeyBetween` из `fractional-indexing-jittered`.
+  Позиция — это строковый ключ (`position: string`), «jittered»-вариант
+  специально снижает коллизии при конкурентных/оффлайн-вставках. Это готовый
+  offline-friendly примитив для перемещений в дереве.
+- **Генерация ID:**
+  [nanoid.utils.ts](../apps/server/src/common/helpers/nanoid.utils.ts) —
+  `generateSlugId` (10 симв.) и `nanoIdGen`. ID можно генерировать на клиенте и
+  принимать на сервере (нужно для оффлайн-создания, см. M3).

+```
+
+Два независимых канала синхронизации:
+- **Контур A** синкается сам через Hocuspocus (Yjs). Руками конфликты не решаем.
+- **Контур B** синкается через outbox: оффлайн-мутации пишутся в журнал в
+  IndexedDB и проигрываются на сервер при реконнекте; конфликты решаются
+  явными правилами (LWW / per-entity).
+
+---
+
+## 4. План реализации по этапам
+
+Этапы инкрементальны: каждый даёт пользователю ощутимый результат и может быть
+смёржен отдельно. Рекомендуемый порядок — строго M0 → M4.
+
+### M0 — PWA shell (фундамент: приложение запускается без сети)
+
+**Зачем:** без service worker установленное приложение без сети не загрузится.
+Это разблокирует всё остальное.
+
+**Что сделать:**
+1. Добавить `vite-plugin-pwa` (Workbox под капотом) в
+   [vite.config.ts](../apps/client/vite.config.ts).
+   - `registerType: 'autoUpdate'` или `prompt` (см. риск R3).
+   - `workbox.globPatterns` — прекэш JS/CSS/wasm/шрифтов/иконок.
+   - `manifest: false` или генерация из существующего
+     [manifest.json](../apps/client/public/manifest.json) (не дублировать).
+   - Навигационный fallback на `index.html` для SPA-роутов.
+   - Runtime caching: `CacheFirst` для статики, **`NetworkOnly` для `/api/**`
+     и `/collab`** на этом этапе (REST-кэш появится в M2; SW не должен молча
+     отдавать устаревшие ответы API).
+2. Зарегистрировать SW в [main.tsx](../apps/client/src/main.tsx)
+   (`registerSW` из `virtual:pwa-register`).
+3. Перенести косметику манифеста/метатегов из Forkmost при желании (бренд,
+   `orientation`, `msapplication-*`). Опционально, на оффлайн не влияет.
+
+**Файлы:** `apps/client/vite.config.ts`, `apps/client/src/main.tsx`,
+`apps/client/public/manifest.json`, `apps/client/index.html`.
+
+**Критерий приёмки:** приложение устанавливается, после первой загрузки
+открывается **без сети** (виден shell/лэйаут, а не пустой экран);
+обновление версии SW не ломает открытую сессию.
+
+**Риск:** низкий. Изолированный слой, кода приложения не трогает.
+
+---
+
+### M1 — Укрепление оффлайна тела документа (Контур A)
+
+**Зачем:** убрать известные грабли Yjs и сделать поведение предсказуемым.
+
+**Что сделать:**
+1. **Закрыть ловушку «rebuild ydoc из JSON».** В
+   [persistence.extension.ts](../apps/server/src/collaboration/extensions/persistence.extension.ts)
+   `onLoadDocument` при пустом `page.ydoc` пересобирает документ из
+   `page.content` через `TiptapTransformer.toYdoc(...)`. Если это сработает,
+   пока оффлайн-клиент держит свой `Y.Doc` со своими client-id, при мёрже
+   возможно **дублирование контента** (классическая Yjs-ловушка).
+   - Гарантировать, что `ydoc` всегда персистится (после первого сохранения он
+     есть) и ветка rebuild не выполняется для страниц, у которых живут
+     оффлайн-клиенты. Минимум — единожды мигрировать `content → ydoc` для всех
+     страниц и далее считать `ydoc` единственным источником правды для тела.
+2. **Индикатор оффлайна/синка в UI.** Уже есть `yjsConnectionStatusAtom` и
+   `isLocalSynced/isRemoteSynced` в
+   [page-editor.tsx](../apps/client/src/features/editor/page-editor.tsx).
+   Показать состояние («оффлайн», «есть несинхронизированные правки»,
+   «синхронизировано»).
+3. **Заголовок страницы → в Yjs (рекомендуется).**
+   [title-editor.tsx](../apps/client/src/features/editor/title-editor.tsx)
+   сохраняет заголовок REST-ом (дебаунс 500 мс) — оффлайн это не работает и
+   расходится с телом. Варианты:
+   - (a) перенести заголовок в тот же `Y.Doc` (чистое CRDT-решение), либо
+   - (b) тащить заголовок через outbox из M3 (LWW). Решение зафиксировать
+     до старта M3 (см. открытый вопрос Q1).
+
+**Файлы:** `apps/server/src/collaboration/extensions/persistence.extension.ts`,
+`apps/client/src/features/editor/page-editor.tsx`,
+`apps/client/src/features/editor/title-editor.tsx` (если вариант a).
+
+**Критерий приёмки:** правки тела уже открытой страницы, сделанные оффлайн,
+после реконнекта появляются на сервере и у других клиентов без дублей и потерь;
+в UI виден статус синка.
+
+**Риск:** средний (Yjs-семантика, миграция `content → ydoc`).
+
+---
+
+### M2 — Оффлайн-чтение и навигация (Контур B, read-path)
+
+**Зачем:** оффлайн нужно видеть дерево, список и метаданные, иначе некуда
+переходить; и нужно префетчить страницы «на оффлайн».
+
+**Что сделать:**
+1. **Персист React Query на диск.** Обернуть экспортируемый `queryClient` из
+   [main.tsx](../apps/client/src/main.tsx) в
+   `PersistQueryClientProvider` с IndexedDB-persister
+   (`@tanstack/query-persist-client-core` + idb-хранилище).
+   - Кэшировать: дерево пространства, список страниц, метаданные страницы,
+     комментарии. Выставить разумный `maxAge`/`gcTime`.
+   - Версионировать кэш (`buster`) по версии приложения, чтобы не «залипал»
+     после деплоя.
+2. **«Сделать доступным оффлайн».** Действие для пространства/ветки: префетч
+   метаданных **и** прогрев `IndexeddbPersistence` для тел страниц (открыть/
+   подгрузить `ydoc` каждой целевой страницы заранее), т.к. сейчас локально
+   лежат только *ранее открытые* страницы.
+3. **Runtime caching API в SW (read-only).** Для GET-эндпоинтов навигации —
+   `StaleWhileRevalidate`/`NetworkFirst` с фолбэком на кэш. Мутации (POST) —
+   по-прежнему мимо кэша (их берёт на себя M3).
+
+**Файлы:** `apps/client/src/main.tsx`, новый модуль
+`apps/client/src/lib/offline/` (persister, prefetch), точечно — хуки списков/
+дерева в `features/page/tree`.
+
+**Критерий приёмки:** после прогрева и ухода в оффлайн пользователь видит дерево
+и список, открывает заранее подготовленные страницы и читает их тело и
+комментарии.
+
+**Риск:** средний (консистентность кэша, инвалидция после деплоя).
+
+---
+
+### M3 — Outbox для мутаций (Контур B, write-path) — ядро оффлайн-синка
+
+**Зачем:** дать оффлайн-создание/редактирование структурных данных с
+последующим проигрыванием на сервер.
+
+**Что сделать:**
+1. **Очередь мутаций (outbox) в IndexedDB.** Журнал операций
+   `{ id, entity, op, payload, clientId, baseVersion, createdAt, status }`.
+   Использовать **offline/paused mutations TanStack Query**
+   (`onlineManager` + `queryClient.resumePausedMutations()` + персист пауз),
+   либо отдельный модуль `apps/client/src/lib/offline/outbox.ts`.
+2. **Клиентская генерация ID.** Для оффлайн-создания страниц/комментариев
+   генерировать `id`/`slugId` на клиенте тем же алфавитом, что и
+   [nanoid.utils.ts](../apps/server/src/common/helpers/nanoid.utils.ts).
+   Для позиций в дереве — `generateJitteredKeyBetween` из
+   `fractional-indexing-jittered` (тот же пакет, что на сервере).
+3. **Идемпотентный upsert на сервере.** Эндпоинты `/pages/create`,
+   `/comments/create` и т.д. должны принимать клиентский `id` и быть
+   идемпотентными по нему (повторная отправка из очереди не должна плодить
+   дубликаты). Точки входа:
+   [page-service.ts](../apps/client/src/features/page/services/page-service.ts),
+   [comment-service.ts](../apps/client/src/features/comment/services/comment-service.ts)
+   и соответствующие контроллеры сервера.
+4. **Optimistic updates + откат.** Применять мутацию к кэшу сразу; при
+   неуспешном проигрывании после реконнекта — откат/пометка конфликта.
+5. **Правила разрешения конфликтов** (см. §5).
+6. **Проигрывание при реконнекте** в порядке `createdAt`, с экспоненциальным
+   backoff и идемпотентностью.
+
+**Файлы:** новый `apps/client/src/lib/offline/outbox.ts`, обёртки над
+`features/*/services/*`, серверные контроллеры/сервисы соответствующих
+сущностей (idempotent upsert).
+
+**Критерий приёмки:** оффлайн можно создать страницу, отредактировать заголовок,
+оставить комментарий, переместить страницу; после реконнекта всё появляется на
+сервере один раз (без дублей), конфликты разрешаются по заданным правилам.
+
+**Риск:** высокий (это самостоятельный класс багов синхронизации; требует
+серверных изменений и тестов на конфликты).
+
+---
+
+### M4 — Вложения и оффлайн-авторизация
+
+**Что сделать:**
+1. **Вложения/картинки оффлайн.** Очередь загрузок: blob кладётся в локальный
+   кэш (Cache API/IndexedDB), в документ вставляется ссылка на локальный
+   ресурс; при реконнекте файл доуплоадивается, ссылка переписывается на
+   серверную. Точка входа — `features/attachments`.
+2. **Оффлайн-толерантная авторизация.** В
+   [api-client.ts](../apps/client/src/lib/api-client.ts) `401`/сетевые ошибки
+   **не должны** выкидывать на логин при отсутствии сети — отличать «нет сети»
+   от «реально разлогинен». Collab-токен (JWT с TTL,
+   [page-editor.tsx](../apps/client/src/features/editor/page-editor.tsx) L166–181)
+   оффлайн не обновить — синк должен просто ждать реконнекта, не ломая
+   локальную работу.
+
+**Критерий приёмки:** оффлайн-вставка картинки доезжает после реконнекта;
+протухший токен/нет сети не выкидывают пользователя из приложения и не теряют
+локальные правки.
+
+**Риск:** средний.
+
+---
+
+## 5. Правила разрешения конфликтов (Контур B)
+
+CRDT здесь нет, правила задаём явно по типам сущностей:
+
+| Сущность | Стратегия |
+|---|---|
+| **Тело документа** | Yjs (CRDT) — руками ничего не решаем. |
+| **Комментарии** | Почти append-only. LWW по полю + дедуп по `clientId`. Простейший случай. |
+| **Метаданные страницы** (заголовок, иконка) | Last-Write-Wins по `updatedAt`. |
+| **Перемещение в дереве** | Самый сложный случай. Позиции — строковые fractional-ключи (`generateJitteredKeyBetween`), что снижает коллизии вставок. Нужен серверный реконсилер для «родитель удалён, а ребёнок перемещён» и конкурентных move: правило «удаление побеждает перемещение» (или наоборот — зафиксировать), плюс перегенерация позиции при коллизии. |
+| **Удаление vs правка** | Зафиксировать политику: правка удалённой сущности → конфликт в UI либо «удаление выигрывает». |
+
+---
+
+## 6. Подводные камни (читать до старта)
+
+1. **Yjs rebuild из JSON → дубли.** Ветка `content → toYdoc` в
+   `onLoadDocument` опасна для долго-оффлайновых клиентов. Закрыть в M1.
+2. **Инвалидция кэша после деплоя.** Персист React Query и precache SW должны
+   версионироваться по версии приложения (`buster`/`globPatterns` хэши), иначе
+   пользователь застрянет на старом UI/данных.
+3. **Обновление service worker.** `autoUpdate` может перезагрузить вкладку с
+   несохранёнными правками. Для редактора предпочтительнее `prompt`-стратегия
+   (показать «доступно обновление», применить по согласию).
+4. **Идемпотентность обязательна.** Любая мутация из outbox может отправиться
+   повторно (реконнект/ретрай). Без серверного upsert по `clientId` — дубли.
+5. **Рост IndexedDB.** Прогрев тел страниц «на оффлайн» и кэш блобов могут
+   занять много места. Нужны лимиты/очистка (LRU).
+6. **Редирект на логин при сетевой ошибке.** Сейчас `401` → `redirectToLogin`.
+   Оффлайн это выкинет пользователя и потеряет контекст — чинить в M4.
+
+---
+
+## 7. Зависимости (npm)
+
+| Пакет | Зачем | Этап |
+|---|---|---|
+| `vite-plugin-pwa` (+ Workbox) | SW, precache app-shell, генерация манифеста | M0 |
+| `@tanstack/query-persist-client-core` | Персист React Query на диск | M2 |
+| `idb` или `idb-keyval` | Обёртка над IndexedDB (persister/outbox/blob-кэш) | M2–M4 |
+| `fractional-indexing-jittered` | Клиентская генерация позиций (уже есть на сервере) | M3 |
+
+`yjs`, `y-indexeddb`, `@hocuspocus/provider` — **уже** в проекте, доустанавливать
+не нужно.
+
+---
+
+## 8. Объём работ vs ценность (для приоритизации)
+
+| Уровень | Этапы | Что пользователь получает |
+|---|---|---|
+| **Минимальный** | M0 + M1 | Приложение грузится оффлайн; уже открытые страницы редактируются и синкаются (тело + заголовок). Навигация — только по закэшированному. |
+| **Средний** | + M2 + M3 | Оффлайн-навигация по подготовленным пространствам; оффлайн-создание страниц и комментариев с синком и LWW-конфликтами. |
+| **Полный** | + M4 (и при необходимости — переезд на синк-движок) | Вложения оффлайн, устойчивая авторизация. Полноценный local-first. |
+
+Прагматичный путь: довести **M0+M1** (это ~80% «редактирую то, что открыл»),
+затем M2/M3 инкрементально. Полный синк-движок (RxDB / ElectricSQL / PowerSync /
+Replicache / TanStack DB) рассматривать только если оффлайн станет ключевым
+сценарием продукта — это существенный рефакторинг данных и бэкенда.
+
+---
+
+## 9. Открытые вопросы (зафиксировать до реализации)
+
+- **Q1.** Заголовок страницы: переносим в Yjs (M1, вариант a) или гоним через
+  outbox (M3, вариант b)? Рекомендация — (a), меньше конфликтных правил.
+- **Q2.** Политика конфликта «удаление vs правка»: «удаление выигрывает» или
+  явный конфликт в UI?
+- **Q3.** Стратегия обновления SW для редактора: `autoUpdate` или `prompt`?
+  Рекомендация — `prompt`.
+- **Q4.** Лимиты локального хранилища (сколько пространств/страниц/блобов
+  держать оффлайн, политика вытеснения).
+- **Q5.** Целимся в инкрементальный путь (M0…M4) или сразу в синк-движок (уровень
+  «полный»)? От этого зависит, переписывать ли REST-слой.

+
+## 10. Чеклист реализации
+
+- [ ] M0: `vite-plugin-pwa` подключён, SW регистрируется, app-shell в precache,
+      `/api` и `/collab` — `NetworkOnly`.
+- [ ] M0: приложение открывается без сети (shell виден).
+- [ ] M1: ветка rebuild ydoc из JSON обезврежена; миграция `content → ydoc`.
+- [ ] M1: индикатор статуса синка в UI.
+- [ ] M1: заголовок переведён в Yjs (или решение Q1 принято).
+- [ ] M2: React Query персистится в IndexedDB, кэш версионирован.
+- [ ] M2: действие «сделать доступным оффлайн» (метаданные + прогрев `ydoc`).
+- [ ] M3: outbox в IndexedDB, клиентские ID, идемпотентный upsert на сервере.
+- [ ] M3: optimistic updates + откат; правила конфликтов реализованы.
+- [ ] M4: очередь загрузки вложений + локальный blob-кэш.
+- [ ] M4: авторизация толерантна к оффлайну (нет редиректа на логин при отсутствии сети).

+# Потоковая диктовка (realtime STT) — дизайн
+
+> Статус: **черновик / дизайн**. Реализация ещё не начата.
+> Исходный кейс: при диктовке текст должен появляться **по мере речи**, а не одним
+> куском после остановки записи.
+>
+> Принятые на старте предпосылки (требуют подтверждения, см. §3 «Развилки»):
+> - **Семантика** — настоящий realtime: аудио стримится во время речи, частичные
+>   расшифровки (`delta`) дописываются в редактор немедленно (~150–300 мс до
+>   первого частичного текста на проводном соединении).
+> - **Провайдер** — OpenAI Realtime API (или совместимый: Azure OpenAI). Это
+>   ломает текущую провайдер-агностичность диктовки (см. §2) — realtime становится
+>   **опциональной** возможностью поверх существующей пакетной диктовки, а не
+>   заменой ей.
+
+---
+
+## 1. Что есть сейчас (пакетная диктовка)
+
+Текущая диктовка — строго «запиши целиком → отправь → получи весь текст», без
+какого-либо стрима:
+
+**Клиент.**
+- [use-dictation.ts](../apps/client/src/features/dictation/hooks/use-dictation.ts) —
+  стейт-машина захвата на `MediaRecorder`. Чанки копятся в `chunksRef` в
+  `recorder.ondataavailable`, но **никуда не уходят по ходу записи**; единый `Blob`
+  собирается только в `recorder.onstop` и одним `multipart`-POST отправляется на
+  транскрипцию. Кодек — сжатый `audio/webm;codecs=opus` (Safari: `audio/mp4`).
+- [dictation-service.ts](../apps/client/src/features/dictation/services/dictation-service.ts) —
+  `transcribeAudio(blob, filename)` → `POST /ai-chat/transcribe`.
+- [mic-button.tsx](../apps/client/src/features/dictation/components/mic-button.tsx) —
+  кнопка с состояниями `idle → recording → transcribing → idle`.
+- [dictation-group.tsx](../apps/client/src/features/editor/components/fixed-toolbar/groups/dictation-group.tsx) —
+  снапшотит каретку в `onStart`, вставляет **готовый** текст в зафиксированную
+  позицию, клампит её под текущий размер документа (учёт коллаб-дрейфа).
+- В чате — тот же `MicButton` в [chat-input.tsx](../apps/client/src/features/ai-chat/components/chat-input.tsx),
+  текст дописывается в черновик сообщения.
+
+**Сервер.**
+- Эндпоинт `POST /ai-chat/transcribe` в
+  [ai-chat.controller.ts](../apps/server/src/core/ai-chat/ai-chat.controller.ts#L195-L281):
+  гейт `settings.ai.dictation === true` (иначе 403), приём файла до 25 МБ,
+  whitelist MIME, троттлинг 20 req/min на пользователя, маппинг MIME→`format`,
+  вызов `AiTranscriptionService.transcribe()`.
+- [ai-transcription.service.ts](../apps/server/src/core/ai-chat/ai-transcription.service.ts) —
+  тонкая обёртка над `AiService.transcribe()`.
+- [ai.service.ts](../apps/server/src/integrations/ai/ai.service.ts#L120-L187) —
+  два пути по `sttApiStyle`: `multipart` (AI SDK `experimental_transcribe`,
+  OpenAI/speaches/faster-whisper/Ollama) и `json` (base64 на
+  `{baseURL}/audio/transcriptions`, OpenRouter). Оба возвращают **весь текст за
+  один вызов**, без SSE/WS.
+- Конфиг STT — per-workspace в `settings.ai.provider` (`sttModel`, `sttBaseUrl`,
+  `sttApiStyle`), ключ зашифрован в `ai_provider_credentials`, расшифровывается
+  только в [ai-settings.service.ts](../apps/server/src/integrations/ai/ai-settings.service.ts#L113-L157)
+  (`resolve`) и **никогда не логируется и не уходит клиенту** (только маска
+  `hasSttApiKey`).
+
+**Вывод.** «По мере речи» в текущей архитектуре невозможно в принципе: текст
+рисуется одним куском в `onstop`. Нужен принципиально другой транспорт.
+
+---
+
+## 2. Главное архитектурное противоречие
+
+Пакетная диктовка **провайдер-агностична**: работает с любым OpenAI-совместимым
+`/audio/transcriptions` (включая self-hosted speaches/faster-whisper и Ollama)
+просто через `sttBaseUrl` + `sttApiStyle`.
+
+Realtime STT — **не** часть OpenAI-совместимого REST. Это отдельный протокол
+(WebSocket/WebRTC + событийная модель), который реализуют единицы провайдеров:
+OpenAI Realtime, Azure OpenAI Realtime, и (с другим набором событий) пара сторонних
+вроде Together AI. Self-hosted whisper-серверы его, как правило, **не умеют**.
+
+Поэтому realtime нельзя «просто включить» вместо пакетной диктовки. Дизайн исходит
+из того, что:
+
+1. Пакетная диктовка (§1) **остаётся** как дефолт и фоллбэк.
+2. Realtime — **опциональная** возможность, доступная только когда workspace
+   настроен на realtime-совместимый провайдер (новый флаг/поле конфига, см. §5).
+3. Если realtime не настроен или соединение не поднялось — UI прозрачно
+   деградирует к пакетному пути.
+
+---
+
+## 3. Контракт провайдера (OpenAI Realtime, transcription session)
+
+Сверено с актуальной документацией (ссылки в конце). Ключевые факты:
+
+**Создание сессии и эфемерный токен.**
+- REST `POST /v1/realtime/transcription_sessions` (в GA-вариантах —
+  `POST /v1/realtime/client_secrets` с телом-конфигом сессии) возвращает
+  `client_secret.value` — **эфемерный** токен с коротким TTL для браузера.
+  Постоянный ключ воркспейса при этом наружу не отдаётся.
+  > На момент реализации сверить точный эндпоинт и форму тела с текущими доками —
+  > API эволюционирует.
+
+**Транспорт.**
+- **WebRTC** — рекомендуется для браузерного аудио (захват + воспроизведение).
+- **WebSocket** — для серверных аудио-пайплайнов:
+  `wss://api.openai.com/v1/realtime?intent=transcription`, заголовки
+  `Authorization: Bearer <key>` и `OpenAI-Beta: realtime=v1`.
+
+**Формат входного аудио.** `pcm16` (raw 16-bit PCM, mono), частота 16 кГц или
+24 кГц; либо `g711`. **Не** webm/opus и **не** mp4 — то есть текущий
+`MediaRecorder`-путь для realtime неприменим (см. §6, AudioWorklet).
+
+**События клиент→сервер.**
+- `transcription_session.update` (или `session.update`) — конфиг модели/VAD/языка.
+- `input_audio_buffer.append` — чанк аудио (base64 PCM16).
+- `input_audio_buffer.commit` — закрыть сегмент вручную (когда VAD выключен).
+
+**События сервер→клиент.**
+- `conversation.item.input_audio_transcription.delta` — поле `delta` с
+  инкрементальным текстом (частичная расшифровка).
+- `conversation.item.input_audio_transcription.completed` — поле `transcript` с
+  финальным текстом сегмента. У обоих есть `item_id` для сопоставления сегментов.
+- `error` — ошибки сессии.
+
+**Turn detection / VAD.** `turn_detection: { type: "server_vad" }` —
+сервер сам нарезает речь на сегменты и эмитит `completed` на границе паузы; для
+непрерывной диктовки это удобнее ручного commit. Модели: `gpt-4o-transcribe`,
+`gpt-4o-mini-transcribe`, потоковая `gpt-realtime-whisper` (у неё настраиваемая
+задержка `delay`: `minimal…xhigh` — баланс «латентность ↔ качество»).
+
+> Важно: `delta`-события дают **черновой** текст, который последующие события
+> могут **переписать**. UI должен уметь заменять ранее показанный частичный текст
+> (см. §3 «Развилка B» про вставку в редактор).
+
+---
+
+## 4. Развилка A — транспорт: прямое WebRTC vs серверный WS-прокси
+
+### Вариант A1 — браузер ↔ OpenAI напрямую (WebRTC, эфемерный токен)
+Наш сервер только минтит эфемерный токен (`/realtime/transcription_sessions`
+постоянным ключом воркспейса), браузер сам устанавливает WebRTC к OpenAI и
+получает `delta`/`completed`.
+
+- **Плюсы:** минимальная латентность (нет лишнего хопа), аудио не идёт через наш
+  сервер (нет нагрузки на bandwidth), меньше серверного кода.
+- **Минусы:**
+  - Работает **только** с настоящим OpenAI/Azure (нужна поддержка эфемерных
+    токенов и WebRTC) — `sttBaseUrl` на self-hosted/прокси-шлюз тут бесполезен.
+  - Браузер устанавливает соединение с внешним хостом напрямую — мимо нашего
+    [ssrf-guard](../apps/server/src/core/ai-chat/external-mcp/ssrf-guard.ts) и
+    серверного троттлинга/гейтинга на уровне каждого сообщения (гейт можно
+    проверить только в момент минтинга токена).
+  - Эфемерный токен живёт в браузере (короткий TTL смягчает, но это всё же
+    выдача наружу производного секрета).
+  - WebRTC в браузере (`RTCPeerConnection`, SDP-оффер, обмен через REST) — больше
+    клиентской машинерии и краевых случаев.
+
+### Вариант A2 (рекомендуется) — браузер ↔ наш сервер (WS) ↔ OpenAI (WS)
+Браузер шлёт PCM16-чанки по WebSocket на наш новый gateway; сервер держит upstream
+WS к `wss://api.openai.com/v1/realtime?intent=transcription` с **постоянным**
+ключом воркспейса и проксирует `delta`/`completed` обратно браузеру.
+
+- **Плюсы:**
+  - Ключ **никогда не покидает сервер** — ровно как в текущем коде
+    ([ai-settings.service.ts](../apps/server/src/integrations/ai/ai-settings.service.ts#L138-L154)),
+    эфемерные токены не нужны.
+  - Работает с **любым** realtime-совместимым эндпоинтом через `sttBaseUrl`
+    (OpenAI, Azure, будущий self-hosted), и upstream-URL проходит через
+    SSRF-валидацию перед коннектом.
+  - Гейт `settings.ai.dictation`, аутентификация (JWT воркспейса), троттлинг и
+    лимиты длительности/объёма применяются **на сервере** на каждом соединении.
+  - Совместимо с тем, что в проекте **уже есть WebSocket-инфраструктура** —
+    коллаб-сервер на Hocuspocus + Socket.IO-адаптер на Redis
+    ([collaboration/](../apps/server/src/collaboration/)), и Fastify-приложение.
+- **Минусы:**
+  - Аудио идёт через наш сервер (≈ десятки кбит/с на сессию для PCM16@24k ⇒
+    ~48 КБ/с; терпимо, но это нагрузка и нужно ограничивать конкуррентность).
+  - Двойной хоп добавляет немного латентности (доли сотни мс).
+  - Нужен новый WS-gateway и аккуратный proxy-стейт (бэкпрешер, очистка сокетов).
+
+**Решение (предлагается): A2.** Он единственный согласуется с инвариантами
+кодовой базы — «ключ только на сервере», провайдер-агностичность через `baseURL`,
+SSRF-guard, серверные гейты и троттлинг. A1 оставить как возможную оптимизацию
+латентности «потом», если упрёмся в bandwidth.
+
+Дальнейший дизайн исходит из **A2**.
+
+---
+
+## 5. Развилка B — куда писать частичный текст в редакторе
+
+`delta` — черновой текст, который может быть переписан. Слепо вставлять каждую
+`delta` в документ Tiptap нельзя: (1) каждая правка документа порождает Yjs-апдейт,
+шумит в истории/коллабе и тяжела; (2) переписывание ранее показанного текста
+превращается в постоянные replace по диапазону.
+
+### Вариант B1 — провизорная вставка в документ + замена диапазона
+Вставляем `delta` прямо в документ, запоминаем диапазон провизорного текста,
+на каждую новую `delta`/`completed` заменяем этот диапазон. На `completed` —
+«фиксируем» (диапазон становится обычным текстом).
+
+- **Плюсы:** текст сразу «настоящий», работает для любого приёмника (редактор и
+  чат единообразно), не нужен слой декораций.
+- **Минусы:** активный коллаб + история засоряются промежуточными апдейтами;
+  замена диапазона воюет с коллаб-дрейфом (диапазон надо ремапить, как уже делает
+  [dictation-group.tsx](../apps/client/src/features/editor/components/fixed-toolbar/groups/dictation-group.tsx#L24-L26));
+  откат при отмене сложнее.
+
+### Вариант B2 (рекомендуется для редактора) — ProseMirror-декорация для interim, коммит только финала
+Частичный текст показываем виджет-декорацией (inline widget) у каретки — он **не
+часть документа**, не порождает Yjs-апдейтов и не попадает в историю. В документ
+коммитим только текст из `completed`-сегмента (как сейчас — `insertContentAt` в
+снапшот каретки, с тем же клампом под коллаб-дрейф).
+
+- **Плюсы:** ноль мусора в коллабе/истории до финала; отмена = просто снять
+  декорацию; финальная вставка переиспользует уже существующую и проверенную
+  логику `dictation-group`.
+- **Минусы:** нужна небольшая ProseMirror-плагин-декорация (новый код); «по мере
+  речи» виден interim как подсветка-призрак, а в документ «оседает» по сегментам
+  (на паузах VAD) — на практике это естественный UX (как у системных диктовок).
+
+### Для чата
+В [chat-input.tsx](../apps/client/src/features/ai-chat/components/chat-input.tsx)
+приёмник — обычный `textarea`/draft, декораций нет. Там проще **B1-подобно**:
+показывать `interim` как «хвост» черновика (например, отдельным стейтом, который
+рендерится приглушённо), а на `completed` дописывать в основной черновик. То есть
+интерфейс хука должен отдавать и `interim`, и `final` (см. §6).
+
+**Решение (предлагается):** редактор — **B2** (декорация + коммит финала), чат —
+показ interim-хвоста + коммит финала. Единый хук realtime отдаёт оба потока,
+а приёмник сам решает, как показывать interim.
+
+---
+
+## 6. Детальный дизайн (A2 + B2)
+
+### 6.1 Клиент: захват аудио (PCM16 через Web Audio API)
+`MediaRecorder` отдаёт сжатый webm/opus — для realtime **не подходит**. Нужен
+сырой PCM16:
+
+1. `getUserMedia({ audio: true })` (как сейчас).
+2. `AudioContext` + `AudioWorkletNode` (новый worklet-процессор): забирает
+   Float32-фреймы, ресемплит к 24 кГц mono, конвертит в Int16, шлёт в основной
+   поток.
+3. Чанки PCM16 → base64 → событие `input_audio_buffer.append` на наш WS-gateway
+   (батчинг ~каждые 100–250 мс, чтобы не спамить сообщениями).
+4. На стоп — закрыть worklet, остановить треки (как в текущем `stopTracks`),
+   дослать остаток.
+
+Новый код, в идеале — отдельный хук `use-realtime-dictation.ts` рядом с
+[use-dictation.ts](../apps/client/src/features/dictation/hooks/use-dictation.ts),
+с тем же «фасадом» (`status/start/stop/cancel`) **плюс** колбэки `onInterim(text)`
+и `onFinal(text)`. `MicButton` выбирает реализацию (realtime vs batch) по флагу из
+конфига воркспейса; вся остальная обвязка (тултипы, состояния, обработка ошибок,
+гард двойного клика, очистка на unmount) переиспользуется один-в-один.
+
+> AudioWorklet требует безопасного контекста (HTTPS/localhost) — то же ограничение,
+> что уже есть у `getUserMedia` в текущем хуке. Нужен бандл worklet-файла через
+> Vite (`?url`/`?worker`); сверить с тем, как проект собирает воркеры.
+
+### 6.2 Сервер: WS-gateway + realtime-прокси
+Новый модуль внутри `core/ai-chat` (рядом с `ai-transcription.service.ts`):
+
+- **WS endpoint** (например, `ws://…/ai-chat/realtime-transcribe`). Поднять либо
+  как Nest WebSocketGateway, либо как Fastify-WS-роут — выбрать по тому, что уже
+  используется в проекте (Socket.IO-адаптер на Redis в
+  [collaboration/](../apps/server/src/collaboration/)). На коннекте:
+  - аутентификация JWT воркспейса (как у остальных `/ai-chat` маршрутов);
+  - гейт `settings.ai.dictation === true` (иначе закрыть с понятным кодом/причиной);
+  - троттлинг/лимит одновременных realtime-сессий на пользователя и на воркспейс
+    (realtime дороже пакетной диктовки — нужен явный потолок).
+- **Резолв конфига** через `AiSettingsService.resolve(workspaceId)`: нужны
+  `sttModel`, `sttBaseUrl||baseUrl`, `sttApiKey`. **До** коннекта прогнать
+  upstream-URL через [ssrf-guard](../apps/server/src/core/ai-chat/external-mcp/ssrf-guard.ts).
+- **Upstream WS** к `wss://<base>/realtime?intent=transcription` (npm `ws`),
+  заголовки `Authorization: Bearer <sttApiKey>` + `OpenAI-Beta: realtime=v1`.
+  Сразу отправить `transcription_session.update` с моделью/языком/`server_vad`.
+- **Прокси:** PCM16 от браузера → `input_audio_buffer.append` в upstream;
+  `…transcription.delta` / `…completed` / `error` из upstream → клиенту
+  (можно прозрачно ретранслировать, либо нормализовать в свой минимальный формат
+  `{type:'interim'|'final'|'error', text, itemId}` — предпочтительно
+  нормализовать, чтобы не привязывать клиент к сырой схеме OpenAI и упростить
+  будущую поддержку Azure/иных).
+- **Очистка:** при закрытии любого из двух сокетов — закрыть второй, освободить
+  ресурсы; таймаут простоя; лимит длительности сессии (аналог 120 с в текущем
+  хуке) и лимит суммарного объёма аудио.
+
+Расширить `AiService` (или новый `AiRealtimeService`) методом, инкапсулирующим
+upstream-WS, чтобы контроллер/gateway оставался тонким — симметрично текущему
+`transcribe()`.
+
+### 6.3 Конфиг воркспейса
+Добавить в [ai.types.ts](../apps/server/src/integrations/ai/ai.types.ts) и в
+[ai-settings.service.ts](../apps/server/src/integrations/ai/ai-settings.service.ts):
+- `sttRealtime?: boolean` — включает realtime-путь для воркспейса.
+- `sttRealtimeModel?: string` — модель realtime (например `gpt-4o-mini-transcribe`
+  / `gpt-realtime-whisper`); если пусто — фоллбэк на `sttModel`.
+- (опц.) `sttRealtimeBaseUrl?` — если realtime-эндпоинт отличается от `sttBaseUrl`.
+
+Ключ переиспользуется (`sttApiKey` → fallback `apiKey`), новых секретов не нужно.
+В `getMasked` отдавать новые **несекретные** поля; в `resolve` — как сейчас.
+UI настроек (Workspace settings → AI) — добавить тумблер «Realtime dictation» и
+поле модели рядом с существующими STT-полями; кнопка «Test endpoint» для realtime
+делает короткий тестовый коннект (открыть сессию, послать ~0.5 с тишины, дождаться
+`session.created`/`error`, закрыть) и возвращает `ok|error` через
+`describeProviderError`-подобную нормализацию.
+
+### 6.4 Клиентский конфиг-гейт
+Realtime-кнопку показывать только если `workspace.settings.ai.dictation === true`
+**и** `…ai.provider.sttRealtime === true`. Иначе — текущая пакетная кнопка. Маска
+настроек должна отдавать эти флаги клиенту (несекретные).
+
+---
+
+## 7. Безопасность и соответствие конвенциям
+
+- **Ключ только на сервере** (вариант A2): постоянный ключ не уходит клиенту,
+  эфемерные токены не используются — инвариант
+  [§8 ai-settings](../apps/server/src/integrations/ai/ai-settings.service.ts#L38-L45)
+  сохранён. Ключ не логируется.
+- **SSRF:** upstream realtime-URL валидируется через
+  [ssrf-guard.ts](../apps/server/src/core/ai-chat/external-mcp/ssrf-guard.ts)
+  перед коннектом (особенно если разрешаем кастомный `sttRealtimeBaseUrl`).
+- **Гейт/авторизация/троттлинг** — на сервере, на каждом WS-коннекте; плюс жёсткий
+  лимит одновременных realtime-сессий (это дорого) и лимит длительности.
+- **Обработка ошибок (конвенция проекта).** Любая ошибка (upstream `error`,
+  разрыв сокета, провайдер-таймаут, не настроен realtime, отказ микрофона):
+  - на сервере — лог полностью (имя/сообщение/стек/`cause`, статус upstream) и
+    отдача клиенту **конкретной** причины (не «Something went wrong»), через
+    нормализатор уровня `describeProviderError`;
+  - на клиенте — `console.error(<context>, err)` + нотификация с реальной причиной
+    (как уже сделано в
+    [use-dictation.ts](../apps/client/src/features/dictation/hooks/use-dictation.ts#L187-L213)).
+- **Деградация:** realtime недоступен/упал на старте → молча используем пакетную
+  диктовку (она всегда есть); realtime упал в середине → коммитим уже полученные
+  `completed`-сегменты, показываем причину, предлагаем продолжить пакетно.
+
+---
+
+## 8. Краевые случаи
+
+- **Коллаб-дрейф:** между `start` и каждым `completed` документ мог измениться —
+  ремап/кламп позиции вставки (логика уже есть в `dictation-group`); для interim
+  декорация привязывается к текущей каретке, не к абсолютной позиции.
+- **Отмена записи:** снять декорацию, ничего не коммитить, закрыть оба сокета.
+- **Тишина/нет речи:** VAD не эмитит сегментов — корректно завершить без вставки.
+- **Длинная диктовка:** server_vad нарезает на сегменты автоматически; следить за
+  лимитом длительности и объёма.
+- **Переписывание interim:** поздние `delta` правят ранние — UI всегда показывает
+  последнюю версию текущего (ещё не `completed`) сегмента.
+- **Языки/пунктуация:** прокидывать `language` в конфиг сессии (или авто);
+  модель сама расставляет пунктуацию.
+- **Несколько вкладок / двойной старт:** гард как в текущем хуке + серверный лимит
+  сессий.
+- **Старые браузеры без AudioWorklet:** фоллбэк на пакетную диктовку.
+
+---
+
+## 9. Поэтапный план реализации
+
+1. **Конфиг и гейт.** `ai.types.ts` + `ai-settings.service.ts` (`sttRealtime`,
+   `sttRealtimeModel`), маска, UI-тумблер и «Test endpoint». Без транспорта —
+   просто читается/пишется.
+2. **Серверный realtime-прокси.** WS-gateway + `AiRealtimeService` (upstream WS к
+   OpenAI, SSRF, гейт, троттлинг, нормализация событий, очистка). Покрыть
+   юнит/моками парс событий и закрытие сокетов.
+3. **Клиентский захват PCM16.** AudioWorklet-процессор + `use-realtime-dictation`
+   (фасад `status/start/stop/cancel` + `onInterim/onFinal`), подключение к WS.
+4. **UI interim.** B2-декорация в редакторе + коммит финала через существующую
+   `dictation-group`-логику; в чате — interim-хвост + коммит. Переключение
+   realtime/batch в `MicButton` по флагу конфига.
+5. **Закалка.** Лимиты, таймауты, фоллбэки, нотификации с реальными причинами,
+   нагрузочная проверка одновременных сессий.
+
+---
+
+## 10. Открытые вопросы / риски
+
+- **Подтвердить семантику** (предпосылки в шапке): нужен именно realtime «по мере
+  речи» (A2/B2), а не просто «прогрессивный вывод после стопа» (`stream:true` на
+  `gpt-4o-transcribe` — гораздо дешевле и проще, но текст идёт только **после**
+  остановки записи).
+- **Точная форма Realtime API** (эндпоинт сессии, имена событий, формат аудио)
+  меняется — сверить с актуальными доками на момент реализации.
+- **Стоимость/латентность** realtime заметно выше пакетной диктовки — нужен явный
+  потолок одновременных сессий и, возможно, явное предупреждение админу.
+- **Нагрузка на наш сервер** (аудио через прокси) — измерить на реальной

- *   - `D` (deleted): recover the pageId from the PRE-IMAGE meta (`metaAt(path,
- *       'prev')`) -> DELETE. If no pageId can be recovered, SKIP with a reason
- *       (untracked-file guard, SPEC §8: never delete an untracked page).
- *   - `R` (renamed/moved): same pageId (from current meta), path changed ->
- *       RENAME/MOVE. Resolution of move-vs-rename + the new parentPageId is
- *       DEFERRED to the next increment; here we only record oldPath/newPath/

- * LOOP-CLOSE (SPEC §6 step 3 / §10). After a fully-successful push, when a
- * `pushedCommit` is supplied:

- *
- * LOOP-GUARD DATA (SPEC §10). For every page successfully updated/created the
- * result carries a `pushed` record `{ pageId, updatedAt?, bodyHash }` — the body
- * hash of what was pushed plus the write's `updatedAt` (when the client returned

-/**
- * PURE push planner (SPEC §4/§6/§8). Classifies each diff row into a Docmost
- * action by `pageId` identity, with NO IO (the `metaAt` resolver is injected).
- *
- * Classification rules:
- *   - `A` (added):
- *       - current meta HAS a pageId  -> UPDATE (a restored/copied file whose
- *         page already exists; we push its content rather than create a dup).
- *       - current meta has NO pageId but HAS a non-empty spaceId -> CREATE (a
- *         brand-new local file; the page does not exist in Docmost yet).
- *       - current meta has NO pageId and NO usable spaceId -> SKIP with reason
- *         `create-without-spaceId`: Docmost `create_page` REQUIRES a spaceId
- *         (§16), and a new local file may carry only partial human meta. We
- *         refuse to create rather than guess a space (SPEC §8 guard spirit).
- *   - `M` (modified): current meta has a pageId -> UPDATE content. (If a modified
- *       file somehow lost its pageId it is skipped — there is nothing to target.)
- *   - `D` (deleted): recover the pageId from the PRE-IMAGE meta (`metaAt(path,
- *       'prev')`) -> DELETE. If no pageId can be recovered, SKIP with a reason
- *       (untracked-file guard, SPEC §8: never delete an untracked page).
- *   - `R` (renamed/moved): same pageId (from current meta), path changed ->
- *       RENAME/MOVE. Resolution of move-vs-rename + the new parentPageId is
- *       DEFERRED to the next increment; here we only record oldPath/newPath/
- *       pageId. If the renamed file has no recoverable pageId it is SKIPPED.
- *       (`C` copy is treated the same as `R` for recording purposes.)

- * `refs/docmost/last-pushed` or the `docmost` mirror, so a re-run retries the
- * whole batch cleanly (the already-applied pages are idempotent re-applies).
- *
- * LOOP-CLOSE (SPEC §6 step 3 / §10). After a fully-successful push, when a
- * `pushedCommit` is supplied:
- *   - advance `refs/docmost/last-pushed` to it (what of `main` is in Docmost), AND

- *     `docmost` is not an ancestor of the pushed commit; the result is surfaced
- *     in `docmostFastForward`. On ANY failure, NEITHER ref is advanced.
- *
- * LOOP-GUARD DATA (SPEC §10). For every page successfully updated/created the
- * result carries a `pushed` record `{ pageId, updatedAt?, bodyHash }` — the body
- * hash of what was pushed plus the write's `updatedAt` (when the client returned

-/**
- * Known NON-NULL schema defaults that `markdownToProseMirror` materializes on
- * import, keyed by node/mark type → { attr: defaultValue }.
- *
- * Why this exists: `canonicalizeAttrs` already treats an absent attr as
- * equivalent to an explicit `null`/`undefined`. But several Docmost schema
- * attributes default to a NON-null value, so import fills them in even when the
- * source omitted them — making "attr absent" diverge from "attr at its default
- * value" under a raw deep-equal. To keep "absent ≡ explicit-default", we ALSO
- * drop any attr whose value equals its known schema default. A non-default
- * value (e.g. `orderedList.start: 5`) is NOT a default, so it is KEPT.
- *
- * Every entry below was read from `packages/docmost-client/src/lib/
- * docmost-schema.ts` (the line refs are the exact `default:` declarations) and
- * confirmed to be materialized by an export→import→export round-trip:
- *   - mark `link`    target / rel  — DocmostAttributes + StarterKit link.
- *       StarterKit's link extension defaults `target: "_blank"` and
- *       `rel: "noopener noreferrer nofollow"`; both materialize on import
- *       (empirically confirmed) even when the source had only `href`.
- *   - mark `comment` resolved      — docmost-schema.ts L213-214 (`default: false`).
- *   - node `orderedList` start     — provided by StarterKit's orderedList
- *       (`default: 1`); materializes on import (empirically confirmed).
- *   - node `drawio`/`excalidraw`/`video`/`youtube`/`embed` align — the diagram
- *       attribute set and the media nodes declare `align: { default: "center" }`
- *       (docmost-schema.ts L745-750 diagramAttributes; L564 video; L626 youtube;
- *       L667 embed). The diagram `align` is the one the round-trip materializes
- *       (docmost-schema.ts L745); the media/embed entries normalize the SAME
- *       `align` default for consistency. Note: this only normalizes `align` —
- *       full canonical stability of `embed` is separately limited by the
- *       converter coercing numeric `width`/`height` to strings, which is outside
- *       canonicalize's scope.
- *
- * NOTE: `image` has NO non-null align default — its `align` defaults to `null`
- * (docmost-schema.ts L174), so it is already handled by the null-drop rule and
