+# Codex Instructions for SFERA
+
+Путь проекта для Windows-команд: `R:\codex\SFERA`.
+
+Диск `R:` смонтирован на `\\nas\MST`; используй `R:\codex\SFERA` вместо UNC-пути `\\nas\MST\codex\SFERA`, чтобы Windows/Node/Next не упирались в ограничения сетевого current directory.
+
+Всегда читай:
+
+1. `docs/design-system.md`
+2. `docs/component-architecture.md`
+3. `docs/codex-ui-guidelines.md`
+
+Перед созданием UI:
+- определи бизнес-сущность
+- выбери стандартный page pattern
+- проверь наличие базовых компонентов
+- не создавай новый UI primitive, если есть shadcn/ui компонент
+- делай маленькие файлы
+
+После создания UI:
+- добавь loading/error/empty states
+- проверь accessibility
+- проверь responsive
+- проверь TypeScript
+- добавь комментарии только там, где они реально помогают

+
+## Shared Test Docker Host
+
+- Test and stand verification must be done on the shared Docker host, not on a local Docker Engine.
+- Use SSH alias `test-docker` / `docker-test`.
+- Host: `docker-test.cin.su` (`192.168.200.61`).
+- SSH user: `test`.
+- Preferred Docker endpoint when Docker CLI is available: `ssh://test-docker`.
+- Deploy both backend/server services and frontend services on `docker-test` for integrated testing.
+- Portainer: `http://docker-test.cin.su:9000/`, user `admin`.
+- Do not store the password in repositories or project files; use an SSH key for persistent access.
+
+## Local Workspace Path
+
+- The project is available locally at `Z:\codex\SFERA`.
+- `Z:\codex\SFERA` is a mapped network folder for `\\nas\MST\codex\SFERA`.
+- Prefer `Z:\codex\SFERA` for Windows tooling and frontend commands.
+- Do not fall back to UNC current directories for npm/cmd workflows; Windows `cmd.exe` does not support UNC current directories reliably.

+# Codex Instructions for SFERA
+
+Ты реализуешь SFERA по шагам. Не перескакивай к AI и UI, пока не работает semantic core.
+
+## Абсолютные правила
+
+1. Не писать autonomous code generation до готового SIR + parser + graph.
+2. Каждый parser bug превращать в golden fixture.
+3. Не писать напрямую в Neo4j вне `projection-engine`.
+4. Все изменения в будущем должны быть связаны с task/session/user, но в Phase 1 можно оставить placeholders.
+5. Русский UI и команды по умолчанию, но должен быть выбор английского интерфейса/команд; internal models — English.
+6. BSL parser обязан поддерживать смешанный русский/английский синтаксис 1С в одном тексте.
+7. Любые integration/security/agent слои делать только после core.
+
+## Test stand and workspace
+
+- Тестирование интегрированного проекта проводить на `docker-test` / `test-docker`, а не на локальном Docker Engine.
+- На `docker-test` разворачивать обе части: backend/server services и frontend.
+- Docker endpoint: `ssh://test-docker`.
+- Host: `docker-test.cin.su` (`192.168.200.61`), SSH user: `test`.
+- Portainer: `http://docker-test.cin.su:9000/`, user `admin`; пароль не сохранять в репозитории и проектных файлах.
+- Локальный рабочий путь проекта: `Z:\codex\SFERA`.
+- `Z:\codex\SFERA` — подмонтированная сетевая папка `\\nas\MST\codex\SFERA`.
+- Для Windows/npm/frontend команд использовать `Z:\codex\SFERA`, не UNC current directory.
+
+## Frontend contract
+
+Перед любым изменением frontend:
+
+1. Прочитать `docs/frontend/SFERA_FRONTEND_PRODUCT_CONTRACT.md`.
+2. Прочитать `docs/frontend/SFERA_IDE_UI_CONTRACT.md`.
+3. Если меняется дерево 1С - прочитать `docs/frontend/SFERA_METADATA_TREE_CONTRACT.md`.
+4. Если меняются настройки проекта - прочитать `docs/frontend/SFERA_PROJECT_SETTINGS_CONTRACT.md`.
+5. Если контракт устарел - сначала обновить контракт, затем код.
+6. Все UI-изменения фиксировать в `docs/frontend/SFERA_FRONTEND_CHANGELOG.md`.
+
+Не ломать принятую модель: SFERA = metadata-first semantic configurator for 1C, основной экран = IDE последнего проекта, проект выбирается сверху, левая панель = дерево текущего проекта, основная конфигурация и расширения = configuration-like roots одного уровня, центр = рабочая область, правая панель = контекстные свойства, низ = открытые объекты, tools и status.
+
+Для 1C-specific поведения использовать official 1C docs через ITS/v8.1c.ru/1C DN или локальные knowledge packs. ITS credentials брать только из `.env.local`; реальные credentials не коммитить, не писать в markdown/Dockerfile и не выводить в logs.
+
+## Текущий приоритет
+
+Реализовать Phase 1:
+
+```text
+packages/sir
+rust/crates/bsl-parser
+packages/semantic-kernel
+packages/projection-engine
+packages/incremental-indexer
+```
+
+## Стиль кода
+
+- Python 3.12+.
+- Pydantic v2.
+- Async где есть IO.
+- Rust parser сначала простой и детерминированный.
+- Тесты обязательны.
+- Минимальная магия.
+
+## Definition of Done Phase 1
+
+```text
+1. BSL procedures extracted.
+2. Calls extracted.
+3. Queries extracted.
+4. Writes extracted.
+5. SIR snapshot validates.
+6. Neo4j projection works.
+7. Incremental update works on changed file.

+# SFERA — полный анализ проекта для Codex
+
+## Что строим
+
+SFERA — серверная semantic SDLC платформа для 1С:
+
+- semantic graph 1С-конфигурации;
+- полноценная IDE-среда для ручной и AI-assisted разработки 1С;
+- object-level versioning вместо обязательного Git;
+- task-linked изменения;
+- review/impact/runtime intelligence;
+- knowledge-aware AI, который умеет анализировать, писать и изменять 1С-код и metadata;
+- агенты EPF/CFE;
+- marketplace/download center;
+- многопользовательская серверная консоль.
+
+## Продуктовая формула
+
+```text
+SIR + Lineage + Object Versioning + Runtime Overlay + Knowledge Base + Collaboration
+```
+
+Расширенная формула продукта:
+
+```text
+Semantic Core + 1C IDE + AI Pair Programmer + Object/Form Designer + Guarded Apply
+```
+
+## Что не делаем в начале
+
+- автоприменение изменений в production;
+- автономное применение AI-изменений без preview/diff/approval;
+- полный live debugger;
+- сложную marketplace-экосистему;
+- heavy frontend до ядра.
+
+## IDE и authoring стратегия
+
+SFERA должна уметь всё, что ожидается от современной IDE для 1С, но опираясь на semantic graph и структуру конфигурации:
+
+- ручное редактирование BSL-кода с подсветкой, диагностикой, навигацией, поиском ссылок и refactoring;
+- AI autocomplete и продолжение кода с учётом текущей процедуры, локальных переменных, параметров, доступных реквизитов, табличных частей, форм, команд, ролей и связей объекта;
+- AI generation для процедур, функций, обработчиков команд, запросов, движений регистров и безопасных шаблонов 1С;
+- создание и изменение объектов 1С: документы, справочники, регистры, общие модули, реквизиты, табличные части, команды, формы и отчёты;
+- visual/object designer для metadata, форм, команд, реквизитов, табличных частей и отчётов;
+- preview/diff всех изменений перед применением;
+- guarded apply: проверка impact, прав, privacy, review findings, style rules и AI policy до записи изменений;
+- AI объясняет, почему предлагает именно такой код, какие объекты будут затронуты и какие риски есть.
+
+## Что берём из 1С Конфигуратора
+
+SFERA не копирует старый интерфейс Конфигуратора, но сохраняет его сильную рабочую модель, знакомую 1С-разработчикам:
+
+- дерево конфигурации как основной навигатор по метаданным, модулям, формам, реквизитам, командам, ролям и регистрам;
+- отдельные рабочие режимы для модуля, формы, реквизитов/табличных частей, команд, свойств, событий и обработчиков;
+- вкладки открытых объектов и быстрый переход между модулем объекта, модулем формы, дизайнером формы, свойствами и событиями;
+- правый инспектор свойств/событий, который меняет содержимое по выбранному объекту или элементу формы;
+- нижние панели проблем, ссылок, output, preview, diff и статуса выполнения;
+- поиск по дереву, объектам, процедурам, событиям, формам и документации.
+
+Поверх этой модели SFERA добавляет то, чего нет в классическом Конфигураторе как единой среды:
+
+- object-level версии и rollback для каждого изменения;
+- semantic diff, impact analysis и guarded apply перед записью;
+- документацию проекта, vendor/BSP docs, базу знаний, паттерны команды и историю решений прямо в IDE;
+- обучение и подсказки для разработчиков по текущему объекту, коду и стандартам команды;
+- AI pair programmer, который умеет читать контекст 1С, писать код, создавать объекты/формы/отчёты и объяснять риски;
+- task/session binding, audit trail, права доступа, privacy policy и учёт AI token/cost impact.
+
+## Первый технический proof
+
+```text
+BSL file
+↓
+Rust parser
+↓
+SIR Snapshot
+↓
+Neo4j graph
+↓
+find_callers / find_callees
+```
+
+## Языковая стратегия
+
+- UI по умолчанию русский.
+- В интерфейсе и командах русский язык используется по умолчанию.
+- Пользователь должен иметь возможность выбрать английский язык интерфейса и английский вариант написания команд.
+- Внутренний код/модели — английский.
+- BSL parser обязан понимать русские и английские ключевые слова: `Процедура/Procedure`, `Функция/Function`, `КонецПроцедуры/EndProcedure` и т.д.
+- В одном BSL-тексте 1С допустима смесь русских и английских ключевых слов/команд; SFERA обязана это поддерживать.
+
+## Git strategy
+
+Git не является обязательным source of truth. История SFERA хранится в Semantic Object Version Store. Git — только optional import/export adapter.

+# SFERA Platform
+
+**SFERA — Semantic Operating Platform for 1C Ecosystems**
+
+SFERA — enterprise semantic platform для анализа, понимания, индексирования, визуализации и AI-оркестрации экосистем 1С.
+
+SFERA также является современной IDE/authoring-средой для 1С: пользователь должен уметь вручную писать код, создавать и менять объекты, формы, команды и отчёты, а AI должен помогать как pair programmer, который видит текущий код, metadata, связи объектов, доступные переменные и правила платформы.
+
+Платформа строит детерминированное semantic core ядро поверх:
+- 1C BSL
+- XML metadata
+- CF/CFE
+- integrations
+- access topology
+- UI semantics
+- scheduled jobs
+- object dependencies
+- runtime graph
+
+SFERA проектируется как:
+
+```text
+Enterprise AI Operating System
+for 1C ecosystems
+```
+
+---
+
+# Core Philosophy
+
+```text
+Semantic truth first.
+AI later.
+```
+
+AI не является источником истины.
+
+Сначала:
+- deterministic parsing
+- semantic graph
+- metadata topology
+- impact analysis
+- dependency resolution
+- integration discovery
+- access analysis
+
+И только потом:
+- AI copilots
+- AI review
+- AI reasoning
+- AI onboarding
+- AI architecture analysis
+- AI migration planning
+
+---
+
+# High-Level Architecture
+
+```text
+1C BSL/XML/CF/CFE
+        ↓
+Rust BSL Parser
+        ↓
+SIR Snapshot
+        ↓

+Neo4j Semantic Graph
+        ↓
+Incremental Indexing
+        ↓
+Impact Analysis
+        ↓
+AI Operating Layer
+```
+
+---
+
+# Main Goals
+
+## Semantic Understanding of 1C
+
+SFERA должна понимать:
+
+- объекты 1С
+- формы
+- команды
+- реквизиты
+- табличные части
+- роли
+- права доступа
+- BSL dependencies
+- integrations
+- scheduled jobs
+- runtime topology
+- object impact
+- UI semantics
+
+---
+
+## 1C IDE and Authoring
+
+SFERA должна давать возможности современной IDE для 1С:
+
+- BSL editor: подсветка, диагностика, folding, outline, go to definition, find references, rename, extract method и безопасные refactoring actions.
+- Semantic autocomplete: продолжение кода с учётом текущей процедуры, параметров, локальных переменных, реквизитов объекта, табличных частей, форм, команд, ролей, интеграций и доступных методов 1С.
+- AI pair programmer: генерация процедур, функций, запросов, обработчиков команд, движений регистров, проверок заполнения и обработчиков форм.
+- Object designer: создание и изменение документов, справочников, регистров, общих модулей, реквизитов, табличных частей, команд и форм.
+- Form/report designer: работа с формами, элементами, командами, обработчиками и отчётами в visual/object-oriented интерфейсе.
+- Diff/preview/apply: любое AI- или ручное изменение проходит через preview, semantic diff, impact analysis, review и подтверждение.
+- Context-aware hints: подсказки не просто по словам, а по текущему объекту 1С, доступным данным, связям, query/write context и runtime/knowledge facts.
+
+AI не ограничивается анализом. Он должен уметь писать код и предлагать структурные изменения, но SFERA обязана показывать последствия и держать контроль применения у пользователя.
+
+---
+
+## Enterprise AI Layer
+
+Поверх semantic graph строится AI operating layer:
+
+- AI code completion
+- AI code generation
+- AI object/form/report generation
+- AI guarded refactoring
+- AI code review
+- AI impact analysis
+- AI onboarding
+- AI architecture assistant
+- AI dependency explorer
+- AI migration assistant
+- AI semantic search
+- AI documentation generation
+- AI risk analysis
+- AI integration analysis
+
+AI должен работать поверх semantic truth: перед предложением кода он учитывает текущий BSL-контекст, AST/SIR, metadata object, форму, доступные реквизиты, табличные части, команды, роли, запросы, регистры, интеграции, knowledge records и privacy policy.
+
+---
+
+## 1C Knowledge Coverage
+
+`GET /projects/{project_id}/knowledge/schema-coverage` показывает покрытие knowledge-records для документов, справочников, реквизитов и табличных частей.
+
+`GET /projects/{project_id}/review` добавляет INFO `Missing 1C schema knowledge`, если узел схемы 1С не связан ни с одной knowledge-записью.
+
+`POST /knowledge/packs` импортирует BSP/vendor documentation pack как набор `KnowledgeRecord` с тегами `pack:{pack_id}` и `vendor:{vendor}`. `GET /knowledge/packs` показывает установленные пакеты знаний.
+
+`GET /projects/{project_id}/patterns` выполняет детерминированный pattern mining по SIR: повторяющиеся чтения таблиц, записи таблиц и совпадающие read/write формы процедур.
+
+## 1C Ownership
+
+`POST /projects/{project_id}/comments` добавляет обсуждение к `target_id` внутри проекта, а `GET /projects/{project_id}/comments/{target_id}` возвращает комментарии по конкретному объекту, задаче или lineage.
+
+`POST /projects/{project_id}/ownership` назначает ответственного на 1С-объект по `lineage_id`.
+
+`GET /projects/{project_id}/objects/ownership/{object_name}` возвращает владельцев документа, справочника, регистра, общего модуля и других корневых объектов 1С.
+
+`GET /projects/{project_id}/review` добавляет INFO `Missing 1C object owner` для 1С-объектов без назначенного владельца, а `GET /projects/{project_id}/report` включает `ownership_count`, `unowned_object_count` и `unowned_objects`.
+
+## 1C Privacy
+
+`POST /projects/{project_id}/privacy/markers` назначает privacy-классификацию на `lineage_id`: `PUBLIC`, `INTERNAL`, `CONFIDENTIAL`, `PERSONAL_DATA`, `SECRET`.
+
+`GET /projects/{project_id}/objects/privacy/{object_name}` возвращает privacy-маркеры самого 1С-объекта и его прямых реквизитов/табличных частей/форм.
+
+`GET /projects/{project_id}/review` добавляет INFO `Unclassified sensitive 1C field` для реквизитов с чувствительными именами вроде ИНН, паспорт, телефон, email, адрес, если они ещё не классифицированы.
+
+## AI Usage Governance
+
+`POST /ai/usage` записывает факт AI-действия: проект, пользователь, модель, операция, prompt/completion токены и стоимость.
+
+`GET /ai/usage/summary` агрегирует AI usage по проекту, пользователю, модели и операции. `GET /ai/policy` показывает текущий token limit и остаток для пользователя.
+
+`GET /projects/{project_id}/report` включает `ai_usage_request_count`, `ai_usage_total_tokens` и `ai_usage_cost`.
+
+`POST /projects/{project_id}/ai/answer-policy` проверяет, можно ли отвечать на AI-вопрос по выбранному 1С-контексту: учитывает token budget, knowledge records, privacy markers и запрет external model calls.

+# 1C Metadata Object Catalog
+
+This catalog is the product source of truth for the 1C metadata tree. It is backed by the official EDT mdclass metamodel and exposed by `/metadata/catalog`.
+
+Primary sources:
+
+- EDT mdclass package: https://edt.1c.ru/dev/edt/2024.2/apidocs/com/_1c/g5/v8/dt/metadata/mdclass/package-summary.html
+- EDT HTTPService: https://edt.1c.ru/dev/edt/2024.2/apidocs/com/_1c/g5/v8/dt/metadata/mdclass/HTTPService.html
+- 1C HTTP services guide: https://1c-dn.com/1c_enterprise/http_services/
+
+Root configuration objects are maintained in `packages/one-c-normalizer/src/one_c_normalizer/metadata_catalog.py` as `METADATA_TYPE_SPECS` plus descriptions in `METADATA_TYPE_DESCRIPTIONS`.
+
+Child metadata elements are maintained in the same module as `METADATA_CHILD_OBJECT_SPECS`.
+
+Important documented structures:
+
+- HTTP service: HTTP service -> URL templates -> methods -> module.
+- Web service: Web service -> operations -> parameters -> module.
+- Integration service: Integration service -> channels -> messages -> module.
+- Registers: register -> dimensions -> resources -> requisites -> forms -> commands -> templates -> rights -> record set/manager modules.
+- Catalogs/plans/documents: object -> requisites -> tabular sections -> forms -> commands -> templates -> rights -> modules, with type-specific groups such as movements or predefined data.

+# Структура объектов метаданных 1С для дерева SFERA
+
+Дата фиксации: 2026-05-09.
+
+Назначение документа: единая опорная модель для загрузчика метаданных из 1С и дерева SFERA IDE. Реальные объекты, имена и состав узлов должны приходить из выгрузки конфигурации 1С/SIR. В коде интерфейса допустимо хранить только типы объектов, правила группировки, иконки и шаблоны подчинённых узлов.

+Отдельной публичной документации `1C:Enterprise 8.5 Developer Guide` на kb.1ci.com при проверке не найдено. До появления официальной ветки 8.5 используем модель 8.3 как базовую и оставляем место под версионные отличия.
+
+## Принципы дерева
+
+1. В Designer/Конфигураторе типы объектов метаданных сгруппированы в дереве конфигурации.
+2. Объект метаданных описывает структуру и поведение, но не хранит конкретные пользовательские данные.
+3. Внутри объектов есть подчинённые объекты: реквизиты, табличные части, формы, команды, макеты, модули, измерения, ресурсы, права и т.д.
+4. SFERA не должна создавать плоский список. Дерево строится по типу объекта и подчинённым коллекциям.
+5. Узел `Задачи 1С` внутри конфигуратора является типом метаданных 1С. Узел `Задачи` верхнего уровня SFERA является системой разработки.

+## Универсальные подчинённые узлы
+
+Эти узлы могут встречаться у разных типов объектов. Загрузчик должен брать фактический состав из 1С, а не создавать все узлы всегда.
+
+- `Реквизиты`
+- `Табличные части`
+- `Формы`
+- `Команды`
+- `Макеты`
+- `Модуль объекта`
+- `Модуль менеджера`
+- `Модуль набора записей`
+- `Права`
+- `Предопределенные данные`
+- `Измерения`
+- `Ресурсы`
+- `Графы`
+- `Значения`

+- `Движения`
+- `Адресация`
+- `СКД`
+- `URL-шаблоны`
+- `Методы`
+- `Контракты`
+- `Обработчики`
+
+## Правило для SFERA
+
+Загрузчик метаданных должен сохранять:
+
+- `metadata_type`: тип объекта 1С;
+- `name`: имя объекта из конфигурации;
+- `synonym`: синоним;
+- `qualified_name`: полное имя вида `Документ.Имя`, `Справочник.Имя.Форма.ФормаЭлемента`;
+- `parent`: родительский узел;
+- `children`: подчинённые коллекции;
+- `module_kind`: тип модуля, если узел является модулем;
+- `rights`: права/ограничения доступа;
+- `extension_origin`: основная конфигурация или расширение;
+- `version_origin`: снимок/версия/задача;
+- `sfera_overlays`: проверки, инциденты, знания, владельцы, runtime-события.
+
+UI-дерево обязано строиться из этой структуры. Любые демонстрационные имена объектов должны быть заменены данными из SIR после подключения реального загрузчика.

+# Codex Instructions for SFERA Docs
+
+## Frontend Contract Rules
+
+Перед любым изменением frontend:
+
+1. Прочитать `docs/frontend/SFERA_FRONTEND_PRODUCT_CONTRACT.md`.
+2. Прочитать `docs/frontend/SFERA_IDE_UI_CONTRACT.md`.
+3. Если меняется дерево 1С - прочитать `docs/frontend/SFERA_METADATA_TREE_CONTRACT.md`.
+4. Если меняются настройки проекта - прочитать `docs/frontend/SFERA_PROJECT_SETTINGS_CONTRACT.md`.
+5. Если контракт устарел - сначала обновить контракт, затем код.
+6. Все UI-изменения фиксировать в `docs/frontend/SFERA_FRONTEND_CHANGELOG.md`.
+
+Frontend SFERA нельзя переводить в dashboard, CRM или файловый редактор. Принятая модель сохраняется:
+
+- SFERA = metadata-first semantic configurator for 1C;
+- основной экран = IDE последнего проекта;
+- проект выбирается сверху;
+- левая панель = дерево текущего проекта;
+- основная конфигурация и расширения = configuration-like roots одного уровня;
+- центр = рабочая область;
+- правая панель = контекстные свойства;
+- низ = открытые объекты, tools и status.
+
+Для 1C-specific поведения использовать официальную документацию:
+
+- ITS;
+- v8.1c.ru;
+- 1C DN;
+- локальные knowledge packs.
+
+ITS credentials передаются только через `.env.local`:
+
+```dotenv
+SFERA_ITS_URL=<ITS_URL>
+SFERA_ITS_USERNAME=<ITS_USERNAME>
+SFERA_ITS_PASSWORD=<ITS_PASSWORD>
+```
+
+Запрещено:
+
+- хранить реальные ITS credentials в репозитории;
+- писать реальные логины или пароли в markdown;
+- писать реальные логины или пароли в Dockerfile;
+- выводить реальные логины или пароли в logs;
+- коммитить `.env.local` и `.env.*.local`.

+# Codex UI Guidelines для SFERA
+
+## Роль Codex
+
+Codex должен работать как senior frontend engineer + product designer.
+
+Он обязан:
+- соблюдать design system
+- использовать русский язык интерфейса и команд по умолчанию
+- предусматривать выбор английского языка интерфейса
+- не генерировать случайные стили
+- переиспользовать компоненты
+- писать TypeScript
+- не ломать архитектуру
+- добавлять loading/error/empty states
+- учитывать права доступа
+- думать о масштабируемости IDE/authoring-среды для 1С
+
+## Перед генерацией экрана Codex должен определить
+
+1. Какая 1С-сущность или IDE-сущность?
+2. Какие действия доступны пользователю?
+3. Какие статусы есть?
+4. Какие поля обязательные?
+5. Нужен ли editor, designer, graph, table, inspector или diff?
+6. Нужен ли AI Copilot?
+7. Нужны ли права доступа?
+8. Нужна ли история изменений?
+9. Нужна ли интеграция с внешним источником?
+10. Нужно ли preview/diff/apply для изменения 1С-кода или metadata?
+
+## Запреты
+
+Codex НЕ должен:
+- использовать inline styles
+- создавать хаотичные цвета
+- использовать Bootstrap
+- делать огромный компонент на 1000 строк
+- хранить business logic в JSX
+- игнорировать loading states
+- игнорировать empty states
+- генерировать mock API без явной пометки
+- смешивать entity-компоненты и базовый UI
+
+## Обязательные states
+
+Каждый экран должен иметь:
+
+- loading
+- error
+- empty
+- success
+- permission denied
+- dirty form / unsaved changes
+- semantic diff / preview
+- guarded apply result
+
+## UI quality checklist
+
+Перед финалом Codex обязан проверить:
+
+- интерфейс адаптивный
+- все кнопки имеют понятный action
+- статусы представлены Badge
+- опасные действия требуют confirmation
+- таблицы имеют фильтры
+- формы валидируются через Zod
+- редактор/дизайнер имеет problems panel и состояние несохранённых изменений
+- дата/время форматируются единообразно
+- AI действия показывают token/cost impact
+- AI-подсказки учитывают текущий BSL-код, объект 1С, переменные, реквизиты, формы и связи
+- есть audit trail для важных действий

+# Design System SFERA
+
+## UI концепция
+
+**SFERA — Enterprise AI Operating System**
+
+Интерфейс должен ощущаться как:
+- Linear
+- Stripe Dashboard
+- Notion
+- Attio
+- ClickUp 3.0
+- Plane
+- VS Code / JetBrains IDE для authoring-сценариев 1С
+
+SFERA не CRM. Основной UI — это современная IDE/операционная среда для 1С: semantic workspace, редактор кода, дерево объектов, дизайнер форм/отчётов, инспектор свойств, diff/preview/apply и AI-помощник.
+
+Классический 1С Конфигуратор используется как reference workflow, а не как visual style. Мы берём рабочие паттерны 1С-разработчика: дерево конфигурации, вкладки объектов, модуль/форма/свойства/события, правый инспектор, нижние панели диагностики и поиск. Визуально это должно быть современно, плотно, спокойно и удобно для долгой работы.
+
+## Визуальный стиль
+
+- чистый enterprise minimalism
+- dark/light режим
+- спокойные нейтральные цвета
+- акцентный цвет для действий
+- cards with soft shadows
+- rounded-2xl
+- минимальный glassmorphism только для важных overlay
+- плотная, но не перегруженная информационная сетка
+
+## Layout principles
+
+### Главная структура
+
+```txt
+AppShell
+├── Sidebar
+├── Topbar
+├── CommandPalette
+├── Workspace
+│   ├── PageHeader

+│   └── SemanticDiff
+└── AI Copilot Panel
+```
+
+## Основные зоны
+
+### Sidebar
+
+- Dashboard
+- Проекты 1С
+- Объекты 1С
+- Редактор BSL
+- Дизайнер объектов
+- Дизайнер форм
+- Отчёты
+- Семантический граф
+- Impact analysis
+- Review
+- Знания
+- AI
+- Интеграции
+- Регламентные задания
+- Настройки
+
+### Topbar
+
+- поиск
+- command palette
+- быстрые действия
+- уведомления
+- профиль
+- переключение проекта/организации
+
+### Right Inspector
+
+Контекстная панель для:
+- объекта 1С
+- процедуры или функции
+- формы, команды или элемента формы
+- реквизита или табличной части
+- отчёта
+- AI анализа
+- истории изменений
+- связанных сущностей
+
+## Компонентные правила
+
+### Карточки
+
+- `rounded-2xl`
+- `border`
+- `bg-card`
+- `shadow-sm`
+- padding минимум `p-4`
+
+### Таблицы
+
+- sticky header
+- фильтры
+- saved views
+- быстрый поиск
+- column visibility
+- bulk actions
+- inline status badge
+- row details через drawer/inspector
+
+### Формы
+
+- разделять на logical sections
+- использовать progressive disclosure
+- показывать validation inline
+- сохранять drafts
+- audit trail для важных изменений
+
+## Цветовые токены
+
+```txt
+background
+foreground
+card
+card-foreground
+muted
+muted-foreground
+border
+input
+primary
+primary-foreground
+secondary
+destructive
+warning
+success
+info

+
+## Статусы
+
+### Задача
+
+```txt
+Новая
+В работе
+На проверке
+Выполнена
+Отменена
+Просрочена
+```
+
+### Сделка
+
+```txt

+Приостановлена
+Закрыта
+```
+
+### Терминал
+
+```txt
+Подключен
+Не подключен
+Отключен банком
+Ошибка настройки
+```
+
+## AI UX
+
+AI должен быть не отдельной страницей, а частью workflow:
+
+- AI Copilot справа
+- подсказки в карточках
+- inline completion в BSL editor
+- context-aware suggestions по текущим переменным, реквизитам, табличным частям, форме и объекту 1С
+- генерация кода, объектов, форм, команд и отчётов через preview/diff/apply
+- объяснение текущего кода и структуры объекта
+- генерация безопасных изменений 1С
+- продолжение кода по текущему контексту
+- объяснение изменений
+- статистика токенов и лимитов
+
+## Knowledge, Docs, Training UX
+
+SFERA должна показывать знания рядом с местом работы, а не прятать их в отдельную wiki:
+
+- документация объекта, формы, отчёта и бизнес-правила доступны из IDE-контекста;
+- база знаний связывается с lineage объекта, процедурами, запросами и событиями формы;
+- training/onboarding показывает рекомендации по текущему коду, стандартам команды и типовым ошибкам;
+- AI отвечает только с учётом доступных знаний, прав и privacy policy;
+- history/versions объясняют, почему объект менялся, какими задачами и решениями это было связано.

+Tailwind CSS
+shadcn/ui
+Radix UI
+lucide-react

+- объектов 1С
+- процедур и функций
+- форм и команд
+- ролей и прав
+- review findings
+- журналов изменений
+- AI usage статистики
+- лимитов
+- интеграций
+
+## Charts
+
+```txt
+Recharts
+Apache ECharts
+```
+
+Для простых dashboard — Recharts.  
+Для тяжелой аналитики и сложных графиков — ECharts.
+
+## Animations
+
+```txt
+Framer Motion
+```
+
+Использовать аккуратно:
+- открытие панелей
+- command palette
+- sidebar
+- drawer
+- карточки задач
+- state transitions
+
+## UI generation tools
+
+```txt
+v0 by Vercel
+shadcn/ui
+shadcn/studio
+Cursor
+Codex
+```
+
+## Почему не Ant Design / Bootstrap
+
+Ant Design подходит для быстрых корпоративных систем, но SFERA должна выглядеть как современный AI enterprise workspace, а не как старая админка.
+
+Bootstrap и старые admin templates не использовать как основу.

+
+## Записи
+
+### 2026-05-11
+
+Initial UI contract created.
+
+Дата: 2026-05-11
+Автор/Codex task: Codex
+Что изменено: Корневой маршрут frontend переведен на IDE последнего проекта; существующий экран настройки проекта вынесен на `/project-settings`; Top Project Bar дополнен настройками проекта, созданием проекта, уведомлениями и профилем; smoke-тесты обновлены под IDE-first модель и новый route настроек проекта.
+Какие файлы: `frontend/sfera-web/src/app/page.tsx`, `frontend/sfera-web/src/app/project-settings/page.tsx`, `frontend/sfera-web/src/components/layout/app-shell.tsx`, `frontend/sfera-web/src/lib/i18n.ts`, `frontend/sfera-web/scripts/smoke-editor-modes.mjs`, `frontend/sfera-web/scripts/smoke-project-setup.mjs`
+Затронутые экраны: основной вход frontend, IDE workspace, project settings
+Изменен ли UI contract: нет
+Нужны ли новые smoke tests: нет, HTML smoke покрывает redirect `/` -> IDE и доступность `/project-settings`
+
+Дата: 2026-05-11
+Автор/Codex task: Codex
+Что изменено: Fallback metadata tree приведен к контрактной модели: проект содержит top-level `Основная конфигурация`, `Расширение: <Имя>`, `SFERA`, `Среды`; расширение использует тот же configuration-like каркас без fake-объектов.
+Какие файлы: `frontend/sfera-web/src/components/editor/ide-workspace.tsx`, `frontend/sfera-web/scripts/smoke-editor-modes.mjs`
+Затронутые экраны: IDE workspace, левая панель metadata tree
+Изменен ли UI contract: нет
+Нужны ли новые smoke tests: нет, HTML smoke проверяет ключевые top-level узлы левой панели
+
+Дата: 2026-05-11
+Автор/Codex task: Codex
+Что изменено: Server-side metadata tree приведен к той же top-level модели для lazy/large-project режима; пути раскрытия теперь идут через `main-configuration`, а lazy tree сохраняет раскрытие `Основная конфигурация`.
+Какие файлы: `services/api-server/src/api_server/main.py`, `services/api-server/tests/test_api.py`, `frontend/sfera-web/src/components/editor/lazy-metadata-tree.tsx`
+Затронутые экраны: IDE workspace, lazy metadata tree
+Изменен ли UI contract: нет
+Нужны ли новые smoke tests: нет, API tests покрывают структуру, HTML smoke покрывает видимые top-level узлы
+
+Дата: 2026-05-11
+Автор/Codex task: Codex
+Что изменено: Project Settings sidebar переименован из wizard в контрактный экран настроек, добавлен список разделов настроек, AI policy и ITS/documentation access с безопасными env placeholders без реальных credentials; default privacy для нового fallback проекта изменен на `METADATA_ONLY`.
+Какие файлы: `frontend/sfera-web/src/components/project-setup/project-setup-client.tsx`, `frontend/sfera-web/src/app/project-settings/page.tsx`, `frontend/sfera-web/scripts/smoke-editor-modes.mjs`
+Затронутые экраны: Project Settings, Top Project Bar, Import Center
+Изменен ли UI contract: нет
+Нужны ли новые smoke tests: нет, HTML smoke проверяет Project Settings и ITS env placeholders
+
+Дата: 2026-05-11
+Автор/Codex task: Codex
+Что изменено: Lazy metadata tree получил полный маппинг contract-first иконок на существующие 1C SVG assets, чтобы top-level проект, основная конфигурация, ветки metadata, группы макетов/событий/движений, бизнес-процессы, задачи и внешние источники не ссылались на отсутствующие файлы.
+Какие файлы: `frontend/sfera-web/src/components/editor/lazy-metadata-tree.tsx`
+Затронутые экраны: IDE workspace, lazy metadata tree
+Изменен ли UI contract: нет
+Нужны ли новые smoke tests: нет, существующий editor smoke покрывает lazy metadata tree shell
+
+Дата: 2026-05-11
+Автор/Codex task: Codex
+Что изменено: Lazy metadata tree очищен от старого `dashboard` route variant; все переходы из дерева теперь строятся напрямую на `/editor`, включая SFERA overview как `mode=overview`.
+Какие файлы: `frontend/sfera-web/src/components/editor/lazy-metadata-tree.tsx`, `frontend/sfera-web/src/components/editor/ide-workspace.tsx`
+Затронутые экраны: IDE workspace, lazy metadata tree
+Изменен ли UI contract: нет
+Нужны ли новые smoke tests: нет, существующий editor smoke покрывает IDE route
+
+Дата: 2026-05-11
+Автор/Codex task: Codex
+Что изменено: `/project-settings` закреплен как экран Project Settings при любом статусе проекта; INDEXED-проект больше не подменяет настройки старым workbench, поэтому настройки проекта остаются доступны из Top Project Bar по контракту.
+Какие файлы: `frontend/sfera-web/src/components/project-setup/project-setup-client.tsx`, `frontend/sfera-web/scripts/smoke-project-setup.mjs`
+Затронутые экраны: Project Settings
+Изменен ли UI contract: нет
+Нужны ли новые smoke tests: нет, project setup smoke обновлен под contract-first Project Settings route
+
+Дата: 2026-05-11
+Автор/Codex task: Codex
+Что изменено: IDE workspace получил contract-first управление панелями: левая навигация сворачивается и меняет ширину, правая Context Inspector и нижняя tool panel сворачиваются, добавлены горячие клавиши `Alt+1`, `Alt+2`, `Alt+3`, `Ctrl+Tab`, `Ctrl+Shift+Tab`, `Ctrl+W`.
+Какие файлы: `frontend/sfera-web/src/components/editor/ide-workspace.tsx`, `frontend/sfera-web/scripts/smoke-editor-modes.mjs`
+Затронутые экраны: IDE workspace, Left Navigation Panel, Main Workspace, Right Context Inspector, Bottom Tool Panel, Open Objects Bar
+Изменен ли UI contract: нет
+Нужны ли новые smoke tests: нет, editor smoke расширен проверкой contract layout markers

+# SFERA Frontend Product Contract
+
+SFERA - это серверная semantic IDE-платформа для 1С, а не dashboard, CRM или файловый редактор.
+
+## Главная модель
+
+- Проект выбирается в верхней панели.
+- Пользователь долго работает внутри одного проекта.
+- Основной экран - IDE workspace последнего проекта.
+- Если проекта нет - пустой workspace с выбором или созданием проекта.
+- Левая панель - навигация по текущему проекту.
+- Центр - рабочая область.
+- Правая панель - контекстные свойства.
+- Нижняя зона - открытые объекты, служебные панели и status bar.
+
+## Product Principles
+
+SFERA должна быть metadata-first: в 1С дерево объектов конфигурации представляет прикладное решение как древовидную структуру логически связанных объектов.
+
+Расширения являются configuration-like структурами: расширение похоже на обычную конфигурацию и тоже представляется деревом объектов.
+
+Формы - visual-first: формы 1С предназначены для просмотра и редактирования данных и могут принадлежать объектам конфигурации или быть общими.
+
+Окно объекта конфигурации в 1С предназначено для редактирования свойств, управления подчиненными объектами и настройки взаимодействия объектов. SFERA должна расширять эту модель, а не заменять ее dashboard-карточками.
+
+## Official 1C Documentation
+
+При проектировании 1C-specific поведения использовать официальные источники:
+
+- ITS;
+- v8.1c.ru;
+- 1C DN;
+- локальные knowledge packs.
+
+ITS credentials нельзя хранить в документации или репозитории. Доступ передается только через `.env.local`.

+# SFERA IDE UI Contract
+
+## 1. Основной экран
+
+После входа открывается:
+
+- последний проект пользователя;
+- либо пустой IDE shell, если проекта нет.
+
+Проект выбирается только в верхней панели.
+
+Запрещено:
+
+- показывать список проектов в левой панели;
+- делать dashboard главным экраном;
+- показывать fake-данные без импортированного проекта.
+
+## 2. Главный Layout
+
+Экран состоит из:
+
+```text
+Top Project Bar
+Left Navigation Panel
+Main Workspace
+Right Context Inspector
+Open Objects Bar
+Bottom Tool Panel
+Status Bar
+```
+
+## 3. Top Project Bar
+
+Содержит:
+
+- SFERA logo;
+- Workspace selector;
+- Project selector;
+- Project settings button;
+- Create project button;
+- Environment selector;
+- Active task selector;
+- Global search;
+- Agent/API status;
+- Notifications;
+- Language;
+- User profile.
+
+Пример:
+
+```text
+SFERA | Workspace v | Project v | Настройки | + Проект | Env v | Task v | Search...
+```
+
+## 4. Левая Панель
+
+Левая панель - навигация текущего проекта.
+
+Она содержит:
+
+```text
+Проект: ERP Demo
+├── Основная конфигурация
+├── Расширение: <Имя>
+├── Расширение: <Имя>
+├── SFERA
+└── Среды
+```
+
+Левая панель должна:
+
+- сворачиваться;
+- менять ширину;
+- поддерживать поиск;
+- поддерживать фильтры;
+- поддерживать lazy loading;
+- поддерживать virtual scroll;
+- сохранять состояние раскрытия узлов.
+
+## 5. Центр
+
+Центр - основная рабочая область.
+
+Там открываются:
+
+- Object Workspace;
+- Code Workspace;
+- Form Designer;
+- Report Designer;
+- СКД Designer;
+- Layout Designer;
+- Project Settings;
+- Task Workspace;
+- Review Workspace;
+- Runtime Workspace;
+- Knowledge Workspace.
+
+## 6. Правая Панель
+
+Правая панель - Context Inspector.
+
+Она показывает свойства выбранного объекта, элемента формы, процедуры, задачи, отчета, регистра, расширения.
+
+Она не является навигацией.
+
+## 7. Open Objects Bar
+
+Внизу отображается панель открытых объектов:

+# SFERA Stand Runbook
+
+## Network API
+
+- API: `http://192.168.200.60:8000`
+- Swagger: `http://192.168.200.60:8000/docs`
+- Health: `GET /health`
+- Summary: `GET /admin/summary`
+
+## Docker
+
+This OS runs inside a VM. Do not install or use a local Docker Engine here.
+
+Use the shared Docker host for Docker/integration stands:
+
+```bash
+docker -H ssh://test-docker ps
+```
+
+Shared host:
+
+- SSH alias: `test-docker` / `docker-test`
+- Host: `docker-test.cin.su`
+- User: `test`
+
+Integrated SFERA testing must be deployed on `docker-test`, including both backend/server
+services and the frontend service. Do not fall back to local Docker Engine for project testing.
+
+## Neo4j
+
+Neo4j runs on `docker-test` as container `sfera-neo4j`.
+
+- Browser: `http://docker-test.cin.su:17474`
+- Bolt: `bolt://docker-test.cin.su:17687`
+- User: `neo4j`
+- Password: `password`
+
+API uses:
+
+```text
+NEO4J_URI=bolt://docker-test.cin.su:17687
+NEO4J_USER=neo4j
+NEO4J_PASSWORD=password
+```
+
+## Rust BSL Parser
+
+Build the parser locally:
+
+```bash
+cd rust
+cargo build -p bsl-parser
+```
+
+API indexing consumes the Rust JSON contract automatically when the built parser is found at
+`rust\target\debug\bsl-parser.exe`. To force a specific parser binary, set:
+
+```text
+SFERA_BSL_PARSER=rust\target\debug\bsl-parser.exe
+```
+
+If no parser binary is configured or auto-discovered, `semantic-kernel` uses the built-in Python parser fallback.
+
+## Runtime Adapter / 1C Access
+
+`sfera-runtime-adapter` is a separate container/service. It must stay separate from `sfera-api`.
+
+Modes:
+
+```text
+RUNTIME_ADAPTER_MODE=mock
+RUNTIME_ADAPTER_MODE=local_1c
+RUNTIME_ADAPTER_MODE=remote_worker
+```
+
+`mock` is the default Docker mode and does not require a 1C platform inside Linux containers. `local_1c` can normalize EDT/XML/file-tree sources without executing Designer. For `.cf`, `.cfe`, archive, and live infobase sources it first returns a safe `designer_dump_planned` response unless execution is explicitly enabled on a trusted worker.
+
+Platform discovery:
+
+- Set `ONEC_DESIGNER_PATH` when the worker has a known Designer CLI path.
+- If it is empty, runtime-adapter tries common install roots such as `C:\Program Files\1cv8\*\bin\1cv8.exe`.
+- Set `ONEC_DISABLE_AUTO_DISCOVERY=true` to turn discovery off in tests.
+- Check `GET /runtime/platform` for `platform_found`, `designer_path`, `discovered_paths`, capabilities, and diagnostics.
+
+Credentials rule:
+
+- Do not store live 1C credentials in repository files, compose files, docs, fixtures, or logs.
+- Use `credentials_ref` such as `runtime://prompt/live-upo` or a real vault reference.
+- Runtime dump plans redact password-like keys in connection strings before returning diagnostics.
+
+Useful local checks, without storing secrets:
+
+```powershell
+Test-Path "C:\EDT\projects\iFCM-UPO"
+Invoke-WebRequest -UseBasicParsing -Uri "http://192.168.200.95/upo/ru_RU/" -TimeoutSec 10
+Get-ChildItem "C:\Program Files\1cv8","C:\Program Files (x86)\1cv8" -Recurse -Filter 1cv8.exe -ErrorAction SilentlyContinue
+```

+
+## Frontend
+
+Frontend app:
+
+```text
+Z:\codex\SFERA\frontend\sfera-web
+```
+
+Use the mapped `Z:` drive. It points to `\\nas\MST` and avoids Windows tooling issues with UNC current directories:
+
+```bat
+cd /d Z:\codex\SFERA\frontend\sfera-web
+npm run dev
+```
+
+Always run frontend `npm` commands from the mapped `Z:` drive. Do not use `\\nas\MST\...` as the current directory: Windows `cmd.exe` does not support UNC current directories and falls back to `C:\Windows`, which makes npm scripts fail with missing `package.json`.
+
+Default URL:
+
+```text
+http://192.168.200.60:3000
+```
+
+Editor direct links:
+
+```text
+http://192.168.200.60:3000/editor?project=demo&mode=module
+http://192.168.200.60:3000/editor?project=demo&mode=form
+http://192.168.200.60:3000/editor?project=demo&mode=events
+http://192.168.200.60:3000/editor?project=demo&mode=learning
+```
+
+Lightweight frontend smoke check against the running stand:
+
+```bat
+cd /d Z:\codex\SFERA\frontend\sfera-web
+npm run smoke:editor
+```
+
+Browser runtime smoke check against the running stand:
+
+```bat
+cd /d Z:\codex\SFERA\frontend\sfera-web
+npm run smoke:editor:runtime
+```
+
+Project Setup / Import Center runtime smoke check against the running stand:
+
+```bat
+cd /d Z:\codex\SFERA\frontend\sfera-web
+npm run smoke:project-setup
+```
+
+Full editor smoke check:
+
+```bat
+cd /d Z:\codex\SFERA\frontend\sfera-web
+npm run smoke:editor:all
+```
+
+Override the checked frontend URL when needed:
+
+```bat
+set SFERA_WEB_URL=http://docker-test.cin.su:3000
+npm run smoke:editor:all
+```
+
+`smoke:editor` checks server-rendered HTML for the overview and editor modes and retries briefly while a freshly started stand settles. `smoke:editor:runtime` launches the installed Chrome/Edge through `playwright-core`, catches browser runtime errors, verifies Monaco in module mode, opens the Versions tab, clicks a version row, checks full version payload details, and exercises metadata draft preview/apply through the API. `smoke:project-setup` prepares the `default` project through the web API proxy, verifies the new Project Setup / IDE Shell route, and saves a metadata draft to workspace history. Set `SFERA_BROWSER_PATH` if Chrome/Edge is installed in a non-standard location.
+
+Docker health smoke can include the Project Setup browser smoke:
+
+```powershell
+.\scripts\smoke-test-docker.ps1 `
+  -ApiUrl http://docker-test.cin.su:8000 `
+  -WebUrl http://docker-test.cin.su:3000 `
+  -Neo4jUrl http://docker-test.cin.su:7474 `
+  -QdrantUrl http://docker-test.cin.su:6333 `
+  -ObjectStorageUrl http://docker-test.cin.su:9000 `
+  -IncludeProjectSetupSmoke
+```
+
+The frontend resolves the API endpoint in this order:
+
+1. `SFERA_API_URL`
+2. `NEXT_PUBLIC_SFERA_API_URL`
+3. the current panel host with API port `8000`
+
+Examples:
+
+```text
+http://192.168.200.60:3000       -> http://192.168.200.60:8000
+http://docker-test.cin.su:3000   -> http://docker-test.cin.su:8000
+http://127.0.0.1:3001            -> http://localhost:8000
+```
+
+If the API moves to another address or port, set:
+
+```text
+SFERA_API_URL=http://api-host:8080
+```
+
+If only the derived API port changes, set:
+
+```text
+SFERA_API_PORT=8080
+```
+
+Do not use `127.0.0.1:8000` as the panel default, because browsers are normally opened from another computer in the LAN. Full Docker stands should run on `docker-test`; local mode is only for the current API + Next.js development loop without a local Docker Engine.
+
+Browser-side editor actions call the API directly, so API CORS must allow the panel origin. By default the API allows localhost, LAN `192.168.*.*` origins, and `docker-test.cin.su`. Override with `SFERA_CORS_ORIGIN_REGEX` only when the stand moves to a different trusted host pattern.
+
+Expected demo projection:
+
+```text
+nodes: 5
+edges: 6
+```
+
+After a project has been projected once to Neo4j, `POST /projects/{project_id}/incremental/file` automatically applies the SIR delta to that project's Neo4j graph. Check `neo4j_projected` / `neo4j_error` in the response.
+
+Object impact includes 1C role access when XML contains role rights, for example `Role -> Right object="Документ.ЗаказПокупателя"`.
+
+Knowledge packs are stored in `knowledge_packs`; importing a BSP/vendor pack also persists enriched `knowledge` records with `pack:{pack_id}` and `vendor:{vendor}` tags for search and coverage.
+
+Pattern mining is available via `GET /projects/{project_id}/patterns?min_support=2` and reports repeated table reads/writes and repeated routine read/write shapes.
+
+Ownership is stored in `collaboration_ownership` and is scoped by project + target lineage. Project review reports `Missing 1C object owner` for root 1C objects without an assigned owner; project report includes ownership and unowned-object counters.
+
+Privacy markers are stored in `privacy_markers` and are scoped by project + target lineage. Review reports `Unclassified sensitive 1C field` for likely sensitive 1C attributes such as ИНН, паспорт, телефон, email, адрес when no privacy classification exists.
+
+AI usage records are stored in `ai_usage`. Use `GET /ai/usage/summary?project_id=...` for dashboard counters and `GET /ai/policy?user_id=...` before AI actions to show token limits and remaining allowance.
+
+AI answer policy is available via `POST /projects/{project_id}/ai/answer-policy`. It does not generate an answer; it returns `allowed`, blocking reasons, warnings, matching knowledge records, privacy markers, and remaining token budget.

+Дата аудита: 2026-05-10.
+
+Этот план фиксирует путь к завершению SFERA как продукта. Он не подменяет
+`IMPLEMENTATION_ORDER.md`, а добавляет проверяемые критерии готовности и текущий статус.
+
+## Текущее состояние

+
+## Phase Plan
+
+### Phase 1 — Semantic Core
+
+Status: mostly complete.
+
+Completed:
+
+- `packages/sir`.
+- `rust/crates/bsl-parser`.
+- Rust `query-parser` foundation.
+- Rust `semantic-engine` foundation.
+- `packages/semantic-kernel`.
+- `packages/projection-engine`.
+- `packages/incremental-indexer`.
+- Golden fixtures for mixed RU/EN syntax, calls, queries, writes, object writes and recordset writes.
+- Same-module routine resolution priority for duplicate routine names.
+- SIR diagnostics for malformed BSL routine/query boundaries.
+- Incremental diagnostic refresh for changed BSL fragments.
+- Routine `Экспорт` / `Export` flags preserved in SIR node attributes.
+- BSL control-flow fixture for calls/writes inside loops and try/except blocks.
+- Form event handler links from XML metadata to BSL routines.
+
+Remaining:
+
+- Keep parser and XML fixtures expanding as new 1C export patterns are encountered.
+
+### Phase 2 — Object Runtime
+
+Status: implemented with tests, needs broader fixtures.
+
+Completed:
+
+- XML metadata fixtures preserve register dimensions/resources as SIR attributes.
+- Semantic versioning classifies object rename/move/update changes.
+- Object impact includes form event handlers and their register writes.
+- XML fixtures cover child-element forms, commands and role rights.
+- Query intelligence reports register read/write dependencies.
+- Transaction topology groups routines by written register target.
+- Object impact can include scheduled-job integration endpoints from the owning module.
+
+Remaining:
+
+- Add more impact/review fixtures for object-level dependency edge cases as new patterns are found.
+
+### Phase 3 — Runtime Intelligence
+
+Status: implemented with tests, needs integration depth.
+
+Remaining:
+
+- Expand transaction/query intelligence with register movement patterns.
+- Connect UI semantics to editor panels and review findings.
+- Add scheduled job and integration cross-links to impact reports.
+
+### Phase 4 — Knowledge System
+
+Status: implemented with tests.
+
+Remaining:
+
+- Add import fixtures for larger BSP/vendor packs.
+- Add coverage reports by metadata subtree.
+
+### Phase 5 — Collaboration
+
+Status: implemented with tests.
+
+Remaining:
+
+- Enforce task/session binding for mutations outside Phase 1 placeholders.
+- Add UI flow coverage for comments/ownership/activity.
+
+### Phase 6 — Governance/Operations
+
+Status: implemented with tests.
+
+Remaining:
+
+- Verify full stand runbook on `test-docker`.
+- Add backup/restore and migration smoke checks.
+
+### Phase 7 — 1C IDE / Authoring
+
+Status: working Next.js IDE exists and passes smoke; advanced authoring remains product work.
+
+Completed:
+
+- Backend and typed frontend API client for symbol search, go to definition and find references.
+
+Remaining:
+
+- Wire editor actions for go to definition, find references and symbol search into IDE panels.
+- Complete semantic autocomplete from SIR + metadata context.
+- Complete guarded apply with preview, semantic diff, impact, review, RBAC/privacy and version record.
+- Complete object/form/report designer flows.
+- Add browser smoke for key authoring flows.
+
+### AI Layer
+
+Status: intentionally gated until semantic truth is stronger.
+
+Remaining:
+
+- Add answer/generation policy enforcement to every AI-facing endpoint.
+- Add prompt/context builders over SIR, metadata, knowledge, privacy and task/session.
+- Add preview-only AI code generation and guarded apply workflow.
+
+## Execution Order From Here
+
+1. Keep all current green checks green with `scripts/check_all.ps1`.
+2. Finish Phase 1 hardening fixtures and diagnostics.
+3. Expand Phase 2/3 fixtures around metadata, impact, query and runtime topology.
+4. Finish guarded apply and object-level authoring API.
+5. Finish IDE authoring UI and smoke coverage.
+6. Add AI pair-programmer only after guarded apply is deterministic.
+7. Verify full stand on local/NAS and shared Docker host.
+
+## Verification
+
+Use:
+
+```powershell
+.\scripts\check_all.ps1
+```
+
+Expected checks:
+
+- `cargo test && cargo build -p bsl-parser`
+- `uv run pytest`
+- `npm run typecheck`
+- `next build`
+- optional frontend smoke checks when API/frontend stand is running.

+## Phase 7 — 1C IDE / Authoring
+
+Reference workflow: берём лучшие рабочие паттерны 1С Конфигуратора, но реализуем их как современную AI IDE. Обязательны дерево конфигурации, вкладки открытых объектов, режимы модуль/форма/свойства/события, инспектор, нижние панели проблем/output/diff и быстрый поиск. Дополнительно SFERA должна объединять версии, документацию, знания, обучение, audit и guarded apply.
+
+1. BSL editor foundation:
+   - syntax highlighting;
+   - diagnostics;
+   - outline;
+   - go to definition;
+   - find references;
+   - symbol search.
+2. Semantic autocomplete:
+   - current procedure/function context;
+   - local variables and parameters;
+   - object attributes;
+   - tabular sections and columns;
+   - form elements and commands;
+   - known 1C platform APIs;
+   - mixed Russian/English 1C syntax.
+3. AI pair programmer:
+   - code continuation;
+   - procedure/function generation;
+   - query generation;
+   - register movement generation;
+   - command/form handler generation;
+   - explanation of proposed code.
+4. 1C object designer:
+   - create/update document/catalog/register/common module metadata;
+   - create/update attributes and tabular sections;
+   - create/update commands, forms, form elements and reports.
+5. Semantic diff and guarded apply:
+   - preview every manual or AI change;
+   - impact analysis before apply;
+   - review findings before apply;
+   - privacy/RBAC checks;
+   - object-level version record;
+   - rollback point.
+6. IDE-grade UX:
+   - editor workspace;
+   - object tree;
+   - mode bar: module/form/properties/events/versions/docs/knowledge/training;
+   - properties inspector;
+   - form/report designer;
+   - terminal/command palette;
+   - AI assistant panel;
+   - problems/references/output panels.
+
+7. Documentation/knowledge/training inside IDE:
+   - docs linked to objects, forms, reports, events and routines;
+   - project/vendor/BSP knowledge available next to the code;
+   - team patterns, decisions and examples surfaced by current context;
+   - learning hints for the selected object and available variables;
+   - search across code, metadata, docs, versions and discussions.
+
+## Frontend/UI Gate
+
+Перед началом UI-этапа перечитать и применить актуальные требования:
+
+- `docs/design-system.md`
+- `docs/codex-ui-guidelines.md`
+- `docs/ui-ux-roadmap.md`
+- `docs/component-architecture.md`
+- `docs/frontend-stack.md`
+- `prompts/system-frontend-architect.md`
+- `prompts/ui-generation-prompt.md`
+
+Ключевой принцип: SFERA UI должен ощущаться как современная Enterprise AI IDE / Operating System для 1С, а не legacy CRM. Каждый экран обязан иметь AppShell-compatible layout, loading/error/empty/permission states, адаптивность, права доступа, audit trail для важных действий, таблицы с фильтрами/saved views/bulk actions и AI token/cost impact для AI-действий. Для authoring-экранов обязательны editor/object tree/properties inspector/problems/diff/preview/apply states.
+
+Язык UI/команд: русский по умолчанию, но каждый пользовательский экран должен иметь выбор английского интерфейса. Команды в интерфейсе также проектируются с русским вариантом по умолчанию и английским вариантом как доступным режимом. 1С-код может смешивать русские и английские ключевые слова в одном тексте; parser/review/UI не должны считать это ошибкой.

+# SFERA Web
+
+Next.js frontend for the SFERA 1C semantic workspace.
+
+## Run On This NAS Workspace
+
+Use the mapped `R:` drive. It points to `\\nas\MST` and avoids Windows tooling issues with UNC current directories.
+
+```bat
+cd /d R:\codex\SFERA\frontend\sfera-web
+npm run dev
+```
+
+Do not run `npm` from the UNC path `\\nas\MST\...`. Windows starts `cmd.exe` in `C:\Windows` for UNC current directories, so package scripts cannot find `package.json`.
+
+The app resolves the API endpoint in this order:
+
+1. `SFERA_API_URL`
+2. `NEXT_PUBLIC_SFERA_API_URL`
+3. the current panel host with API port `8000`
+
+Examples:
+
+- `http://192.168.200.60:3000` -> `http://192.168.200.60:8000`
+- `http://docker-test.cin.su:3000` -> `http://docker-test.cin.su:8000`
+- `http://127.0.0.1:3001` -> `http://localhost:8000`
+
+If the stand moves to another API port, set:
+
+```text
+SFERA_API_URL=http://api-host:8080
+```
+
+You can also override only the derived port:
+
+```text
+SFERA_API_PORT=8080
+```
+
+## Checks
+
+```bat
+cd /d R:\codex\SFERA\frontend\sfera-web
+node_modules\.bin\tsc.cmd -p tsconfig.json --noEmit
+node_modules\.bin\next.cmd build
+npm run smoke:editor
+npm run smoke:editor:runtime
+npm run smoke:project-setup
+```
+
+`npm run smoke:editor` checks the running stand URL. By default it uses `http://192.168.200.60:3000` and verifies that the overview stays a dashboard while editor modes open directly:
+
+- `mode=module`
+- `mode=form`
+- `mode=events`
+- `mode=learning`
+
+Use `SFERA_WEB_URL` to point the smoke check at another host or port. The HTML smoke retries each page briefly while a freshly started stand settles.
+
+`npm run smoke:editor:runtime` opens the running editor in an installed Chrome/Edge through `playwright-core`. It catches browser runtime failures such as Monaco `Runtime TypeError`, verifies that Monaco renders in `mode=module`, opens `mode=versions`, clicks a version row, checks full version payload details, and exercises metadata draft preview/apply through the API.
+
+`npm run smoke:project-setup` checks the new Project Setup / Import Center flow. It prepares the `default` project through the web API proxy, verifies that the indexed Project IDE Shell opens, and exercises metadata draft preview/save to workspace history.
+
+By default the runtime smoke uses the installed Chrome/Edge paths on this Windows stand. Override when needed:
+
+```text
+SFERA_BROWSER_PATH=C:\Path\To\chrome.exe
+SFERA_WEB_URL=http://docker-test.cin.su:3000
+```
+
+Use `npm run smoke:editor:all` to run both the HTML smoke and browser runtime smoke. Browser-side editor actions require API CORS for the panel origin; the API allows LAN panel origins, localhost, and `docker-test.cin.su` by default. The Project Setup smoke uses the Next.js `/api/sfera/...` proxy and therefore also verifies frontend-to-backend routing.

+# SFERA 1C Extension
+
+Исходники расширения SFERA для опубликованной базы 1С.
+
+## Публикация
+
+HTTP-сервис расширения должен быть опубликован с корнем:
+
+```text
+sfera
+```
+
+Тогда URL формируются по правилу платформы 1С:
+
+```text
+http://server/base/hs/sfera/health
+http://server/base/hs/sfera/v1/metadata
+http://server/base/hs/sfera/v1/query
+http://server/base/hs/sfera/v1/data/read
+http://server/base/hs/sfera/v1/data/write
+http://server/base/hs/sfera/v1/metadata/apply
+```
+
+## Возможности
+
+- `health` - проверка публикации, версии расширения и режима безопасности.
+- `metadata.snapshot` - снимок доступных коллекций metadata и объектов.
+- `query.execute` - консоль запросов 1С. По умолчанию read-only/dry-run.
+- `data.read` - чтение данных через ограниченный запрос или менеджер объекта.
+- `data.write` - изменение данных только при явном `allow_mutation`.
+- `metadata.apply` - изменение структуры не выполняется из HTTP runtime. Возвращает план установки `.cfe`; применение делает Windows Agent через Designer.
+
+## Безопасность
+
+Расширение рассчитано на работу за сервером SFERA. Для опасных операций должны быть включены сразу все уровни:
+
+- публикация защищена пользователем 1С/IIS;
+- SFERA передает `X-SFERA-Token`;
+- в проекте включено `sfera_extension_allow_mutation`;
+- запрос содержит `allow_mutation=true`;
+- `dry_run=false`.
+

+- in-memory graph projection for tests and API queries;
+- Neo4j snapshot projection;
+- Neo4j delta projection from `SirDelta`;
+- routine graph queries: procedures, callers, callees, query tables, writes.
+
+Only this package should mutate Neo4j.

+# UI Code Review Prompt
+
+Проведи code review UI для SFERA.
+
+Проверь:
+
+## Architecture
+
+- компонент не слишком большой
+- business logic отделена от JSX
+- есть переиспользуемые entity-компоненты
+- нет дублирования layout
+- корректная структура imports
+
+## UI/UX
+
+- соответствует design system SFERA
+- современный enterprise вид
+- нет хаотичных цветов
+- корректные spacing и typography
+- есть hover/focus/disabled states
+- корректный responsive
+
+## States
+
+- loading
+- error
+- empty
+- permission denied
+- confirmation for destructive actions
+- unsaved changes
+
+## CRM/ERP requirements
+
+- статусы через Badge
+- таблицы имеют фильтры
+- есть audit trail где нужен
+- действия логируются
+- права доступа учтены
+- AI действия показывают модель/лимиты/токены
+
+## Output
+
+Верни:
+1. Critical issues.
+2. Improvements.
+3. Refactor plan.
+4. Files to change.
+5. Final recommended patch.

+# SYSTEM PROMPT: SFERA Frontend Architect
+
+Ты senior frontend architect и product designer проекта SFERA.
+
+SFERA — enterprise CRM/ERP/AI workspace для управления клиентами, сделками, мерчантами, задачами, бордингом, эквайрингом, интеграциями и AI-лимитами.
+
+Твой стек:
+- Next.js
+- React
+- TypeScript
+- Tailwind CSS
+- shadcn/ui
+- TanStack Table
+- TanStack Query
+- Zustand
+- Zod
+- React Hook Form
+- Framer Motion
+- Recharts/ECharts
+
+Ты обязан:
+1. Соблюдать design system SFERA.
+2. Делать современный enterprise UI.
+3. Не использовать Bootstrap/Ant Design/Material UI без прямого запроса.
+4. Делать компоненты маленькими и переиспользуемыми.
+5. Всегда учитывать loading/error/empty/permission states.
+6. Для таблиц использовать фильтры, сортировку, saved views и bulk actions.
+7. Для важных изменений добавлять audit trail.
+8. Для AI действий показывать модель, лимит, стоимость/токены и статус выполнения.
+9. Не создавать хаотичные цвета, spacing и layout.
+10. Писать production-ready TypeScript.
+
+Стиль интерфейса:
+- Linear
+- Stripe Dashboard
+- Notion
+- Attio
+- Plane
+- ClickUp 3.0
+
+Главный UX принцип:
+SFERA должна ощущаться как Enterprise AI Operating System, а не как обычная старая CRM.

+# UI Generation Prompt
+
+Сгенерируй production-ready UI экран для SFERA.
+
+## Контекст
+
+Проект: SFERA  
+Тип: Enterprise CRM/ERP/AI workspace  
+Стек: Next.js + React + TypeScript + Tailwind + shadcn/ui
+
+## Экран
+
+Название экрана: [УКАЗАТЬ]
+Бизнес-сущность: [Клиент / Сделка / Задача / Мерчант / Бординг / AI Usage / Интеграции]
+Основные действия: [УКАЗАТЬ]
+Роли пользователей: [УКАЗАТЬ]
+
+## Обязательные требования
+
+- Современный enterprise UI
+- AppShell-compatible layout
+- PageHeader
+- Toolbar
+- Search
+- Filters
+- Empty state
+- Loading state
+- Error state
+- Permission state
+- Responsive layout
+- Использовать shadcn/ui
+- Использовать Tailwind
+- Использовать lucide-react icons
+- Не использовать inline styles
+- Не использовать случайные цвета
+- Статусы показывать через Badge
+- Опасные действия через confirmation dialog
+- Формы через React Hook Form + Zod
+- Таблицы через TanStack Table
+- AI действия через AI Copilot panel
+
+## Visual style
+
+- rounded-2xl
+- soft shadows
+- clean spacing
+- muted backgrounds
+- dark/light ready
+- dense but readable
+- enterprise premium look
+
+## Вывод
+
+Верни:
+1. Краткое описание UX.
+2. Список компонентов.
+3. Полный код компонентов.
+4. Какие файлы создать.
+5. Какие зависимости нужны.
+6. Что проверить после генерации.
