+# DuckLM — Текущее состояние проекта
+
+**Дата анализа:** 2026-05-21
+**Версия:** 0.2.0
+**Расположение:** `~/git/ducklm_2`
+
+---
+
+## Последние изменения (Phase 1-7)
+
+### Phase 1: MemoryPolicy — LLM-классификация памяти ✅
+- `duck_core/memory/policy.py` — переписан с нуля: LLM-классификация через critic-роль
+- Роль `memory_policy` добавлена в `config/models.yaml` + промпт
+- Интегрирован в RuntimeLoop: `_run_memory_policy()` после каждой задачи
+- События: `memory_policy_decision`, `memory_stored`, `memory_policy_failed`
+- 6 тестов в `tests/smoke/test_memory_policy.py`
+
+### Phase 2: Рефлексия (Critic) — автоматический вызов ✅
+- `_run_reflection()` в RuntimeLoop — transcript из event store → critic → experience
+- Параметр `reflect: bool = True` в `run_chat()`
+- `ExperienceRecorder` передаётся через `create_app()`
+- События: `reflection_completed`, `reflection_failed`
+- 3 теста в `tests/smoke/test_reflection.py`
+
+### Phase 3-4: ContextBuilder v2 + Summary-роль ✅
+- Полностью переписан `duck_core/context_builder.py`
+- Token budget awareness, приоритизация, суммаризация через summary-роль
+- `estimate_tokens()`, `estimate_messages_tokens()` утилиты
+- Подключён model_client для LLM-суммаризации
+- 11 тестов в `tests/smoke/test_context_builder.py`
+
+### Phase 5: VectorMemory — интеграция ✅
+- `VectorMemory` добавлен в RuntimeLoop и `create_app()`
+- **Локальная модель эмбеддингов**: `all-MiniLM-L6-v2` (384 размерности, sentence-transformers)
+- При `memory_stored` также сохраняется в Qdrant (graceful fallback при ошибках)
+- Поддержка двух режимов: локальная модель + remote `/v1/embeddings` endpoint
+- `sentence-transformers` добавлен в зависимости `pyproject.toml`
+- 4 теста в `tests/smoke/test_vector_memory_integration.py`
+
+### Embeddings — архитектура
+
+### Phase 6: Recall-роль ✅
+- Роль `recall` добавлена в `config/models.yaml` + промпт `prompts/roles/recall.md`

+
+### Phase 7: Coder-роль — интеграция ✅
+- `CoderTool` создан в `duck_core/tools/coder.py`
+- Зарегистрирован в `ToolGateway.default()`
+- Описан в `prompts/roles/action.md`
+
+### Статус тестов
+- **72 из 73** smoke-тестов проходят
+- 1 тест (`test_llama_server_connection_live_skip_by_env`) требует живой llama-server
+
+---
+
+## 1. Что такое DuckLM
+
+DuckLM — это **локальная агентная система (cognitive runtime)**, работающая поверх локальных языковых моделей через `llama-server`. Это не inference-сервер, а полноценный когнитивный цикл:
+
+```
+состояние → контекст → мышление → намерение → действие → наблюдение → рефлексия → память → опыт
+```
+
+Ключевая идея: DuckLM — это **оркестратор**, который управляет задачами, инструментами, памятью, навыками и рефлексией, используя локальные LLM через OpenAI-совместимый API (`llama-server`).
+
+---
+
+## 2. Архитектурные принципы
+
+### 2.1. Использование готовых компонентов
+
+| Компонент | Источник |
+|-----------|----------|
+| LLM inference | `llama-server` (llama.cpp, собранный с Vulkan) |
+| Хранение состояния | SQLite (aiosqlite) |
+| Векторная память | Qdrant (через docker-compose) |
+| HTTP API | FastAPI |
+| Web-интерфейс | Jinja2 + ванильный JS |
+| Валидация данных | Pydantic |
+| Конфигурация | PyYAML + python-dotenv |
+
+**Не пишется с нуля:** inference server, model scheduler, vector DB, OpenAI API, MCP, песочница, workflow engine.
+
+**Пишется с нуля:** Duck Core (runtime loop, context builder, model client, event store, tool gateway, approvals, skills, experience, memory policy, FastAPI API, WebChat).
+
+### 2.2. Web/API first
+
+- **WebChat** — интерфейс для человека (порт 8000)
+- **HTTP API** — для кодера, тестов и внешних агентов
+- CLI не входит в обязательную часть (если понадобится — тонкий клиент поверх HTTP API)
+
+### 2.3. Роли моделей — логические, не физические
+
+Роли: `thinker`, `critic`, `coder`, `action`, `summary`, `recall`, `sys_util`.
+
+Все роли в текущей конфигурации указывают на одну физическую модель (`local-main` на порту 8081). Различие между ролями задаётся комбинацией:
+- system prompt
+- temperature
+- max_output_tokens
+- response_format / structured_output
+- memory scope
+- tool permissions
+
+### 2.4. Token budget
+
+```
+DUCK_CTX_SIZE=4096          (в .env, хотя в коде дефолт 65536)
+DUCK_MAX_INPUT_TOKENS=49152
+DUCK_MAX_RECENT_EVENTS_TOKENS=12000
+DUCK_MAX_MEMORY_TOKENS=8000
+DUCK_MAX_SKILL_TOKENS=6000
+```
+
+Output limits по ролям:
+- thinker: 8192
+- critic: 4096
+- coder: 16384
+- action: 2048
+- summary: 4096
+
+---
+

+
+---
+
+## 6. Отступления от плана / дополнительные возможности
+
+### 6.1. Что добавлено сверх плана
+
+1. **ConversationStore** — полноценное управление диалогами (conversations + conversation_messages таблицы), чего не было явно в плане Task 2. План упоминал только tasks и events.
+
+2. **Streaming API** — `POST /v1/chat/stream` с SSE, `POST /v1/tasks/{id}/continue/stream`, `POST /v1/tasks/{id}/password/stream`. В плане не было явно указано streaming.
+
+3. **Password flow** — полный цикл запроса sudo-пароля: `requires_password` → `tool_password_requested` → `/v1/tasks/{id}/password/stream`. В плане не было детализировано.
+
+4. **Activity Drawer в WebChat** — боковая панель с вкладками Events/Commands/Memory, инлайн-терминалы для инструментов, инлайн-одобрения. Значительно больше, чем «пустая WebChat-страница» из этапа 1 ТЗ.
+
+5. **Command Audit** — отдельный тип события `command_audit` для shell-команд с полной метаданной (action_type, risk_level, blocked, approved, returncode).
+
+6. **Scope-aware Memory** — трёхуровневая система скоупов (global/workspace/conversation) с автоматическим infer_scope.
+
+7. **Skill update proposals** — автоматическая запредложений по обновлению скиллов в `skills/_proposals/`.
+
+8. **18 тестов вместо 11 запланированных** — добавлены: `test_chat_api`, `test_conversations`, `test_runtime_reasoning`, `test_runtime_tools`, `test_llama_server_connection`, `test_llama_service_script`, `test_memory_store`.
+
+### 6.2. Что не реализовано (или реализовано частично)
+
+1. **MemoryPolicy — заглушка.** `MemoryPolicy.classify()` всегда возвращает `should_store=False`. Нет LLM-классификации для автоматического сохранения памяти.
+
+2. **ContextBuilder — минимальный.** Нет суммаризации старых events, нет обрезки по token budget, нет приоритизации контекста. Просто склеивает memory + history + user message.
+
+3. **Critic не вызывается автоматически.** `Reflection.reflect()` есть, но не интегрирован в RuntimeLoop — нет автоматической рефлексии после завершения задачи.
+
+4. **Summary роль не используется.** Нет автоматической суммаризации контекста при превышении budget.
+
+5. **Coder роль не используется в основном потоке.** RuntimeLoop вызывает только action и thinker.
+
+6. **Recall роль не определена в конфиге.** В ТЗ упоминается recall, но в `config/models.yaml` её нет.
+
+7. **Sys_util роль не определена в конфиге.** Аналогично.
+
+8. **VectorMemory не интегрирован в RuntimeLoop.** Qdrant-поиск не подключён к основному циклу (MemoryStore использует LIKE-поиск, а не векторный).
+
+9. **WebChat — светлая тема.** В памяти пользователя указано предпочтение тёмной темы, но CSS реализован светлый (`color-scheme: light`, белый фон).
+
+10. **Нет CLI.** Упомянуто в ТЗ как необязательное, но если понадобится — нужно делать.
+
+11. **Нет автоматического применения skill patches.** Предложения пишутся в `skills/_proposals/`, но не применяются автоматически.
+
+### 6.3. Технические заметки
+
+- **Модель:** Qwen3.6 35B A3B, два варианта — nonMTP (основной, порт 8081) и MTP (экспериментальный, порт 8085)
+- **GPU:** Radeon RX580, Vulkan backend, 20 GPU layers
+- **llama-server бинарник:** `./vendor/llama.cpp/build/bin/llama-server`
+- **ctx_size в .env:** 4096 (хотя в коде Settings дефолт 65536)
+- **reasoning-budget:** 512 в .env, `--reasoning-budget 512 --cache-ram 0`
+- **Python:** 3.13 (по путям `__pycache__`)
+
+---
+
+## 7. Структура базы данных (SQLite)
+
+Таблицы:
+- **tasks** — задачи (task_id, status, user_message, workspace, debug, final_response, created_at, updated_at)
+- **events** — события (id, task_id, sequence, event_type, payload_json, created_at)
+- **conversations** — диалоги (id, conversation_id, title, workspace, created_at, updated_at)
+- **conversation_messages** — сообщения диалогов (id, conversation_id, role, content, reasoning_content, task_id, status, created_at)
+- **approvals** — согласования (id, approval_id, task_id, action_hash, normalized_action_json, status, decision, created_at, updated_at)
+- **experience_records** — записи опыта (id, task_id, skill_id, summary, result, what_worked_json, what_failed_json, reusable_lesson, suggested_skill_patch, confidence, created_at)
+- **memories** — память (id, memory_id, text, scope, workspace, conversation_id, memory_type, importance, metadata_json, created_at, updated_at)
+
+---
+
+## 8. Когнитивный цикл (как работает RuntimeLoop)
+
+1. Пользователь отправляет сообщение → `POST /v1/chat` или `/v1/chat/stream`
+2. Создаётся Task + событие `task_created`
+3. ContextBuilder собирает сообщения (memory + history + user message)
+4. **Action loop** (до 4 итераций):
+   - Модель `action` генерирует JSON directive (schema: action_directive.schema.json)
+   - ToolGateway выполняет каждый action через соответствующий инструмент
+   - Если команда требует approval → пауза, создание Approval, ожидание решения
+   - Если sudo → запрос пароля
+   - Результаты собираются как tool_observations
+5. Thinker получает все tool_observations и формирует финальный ответ
+6. Задача завершена → `task_completed`
+7. (Опционально) Reflection через critic — **не автоматизировано**
+
+---

+## Архитектура эмбеддингов
+
+### Локальная модель (основной режим)
+- **Модель**: `all-MiniLM-L6-v2` (sentence-transformers, 384 размерности)
+- **Расположение**: `./models/all-MiniLM-L6-v2/` (safetensors формат)
+- **Библиотека**: `sentence-transformers` (добавлен в pyproject.toml)
+- **Использование**: `VectorMemory._local_embed()` — загрузка модели через `SentenceTransformer`, кодирование в thread pool
+
+### Remote endpoint (fallback)
+- **Endpoint**: `/v1/embeddings` на llama-server или OpenAI-совместимом сервере
+- **Использование**: `VectorMemory._remote_embed()` — HTTP POST запрос
+
+### Поток данных
+1. Зача завершена → `_run_memory_policy()` → LLM классифицирует → `MemoryDecision`
+2. Если `should_store=True` → `MemoryStore.add()` (SQLite) + `VectorMemory.add_memory()` (Qdrant)
+3. При следующем запросе → `MemoryStore.relevant()` (SQLite LIKE) + `VectorMemory.search_memory()` (semantic)
+4. Recall-роль фильтрует релевантные воспоминания через LLM
+
+### Зависимости
+- `sentence-transformers` — для локальной модели
+- `qdrant-client` — для Qdrant (уже был)
+- Qdrant запускается через `docker-compose.memory.yml` (порт 6333)
+| Docker (Qdrant) | ✅ Готово |
+
+**Общий вывод:** Все 4 задачи плана реализованы. Система представляет собой работающий skeleton с полным когнитивным циклом. Основные направления для дальнейшего развития: интеграция рефлексии и summary в основной цикл, LLM-based MemoryPolicy, векторная память, тёмная тема, расширение ContextBuilder.
