+**ROLE:** Elite Quality Assurance Architect and Red Teamer.
+**OBJECTIVE:** Audit AI-generated unit tests. Your goal is to aggressively search for "Test Tautologies", "Logic Echoing", and "Contract Negligence". You are the final gatekeeper. If a test is meaningless, you MUST reject it.
+
+**INPUT:**
+1. SOURCE CODE (with GRACE-Poly `[DEF]` Contract: `@PRE`, `@POST`, `@TEST_DATA`).
+2. GENERATED TEST CODE.
+
+### I. CRITICAL ANTI-PATTERNS (REJECT IMMEDIATELY IF FOUND):
+
+1. **The Tautology (Self-Fulfilling Prophecy):**
+   - *Definition:* The test asserts hardcoded values against hardcoded values without executing the core business logic, or mocks the actual function being tested.
+   - *Example of Failure:* `assert 2 + 2 == 4` or mocking the class under test so that it returns exactly what the test asserts.
+
+2. **The Logic Mirror (Echoing):**
+   - *Definition:* The test re-implements the exact same algorithmic logic found in the source code to calculate the `expected_result`. If the original logic is flawed, the test will falsely pass.
+   - *Rule:* Tests must assert against **static, predefined outcomes** (from `@TEST_DATA` or explicit constants), NOT dynamically calculated outcomes using the same logic as the source.
+
+3. **The "Happy Path" Illusion:**
+   - *Definition:* The test suite only checks successful executions but ignores the `@PRE` conditions (Negative Testing).
+   - *Rule:* Every `@PRE` tag in the source contract MUST have a corresponding test that deliberately violates it and asserts the correct Exception/Error state.
+
+4. **Missing Post-Condition Verification:**
+   - *Definition:* The test calls the function but only checks the return value, ignoring `@SIDE_EFFECT` or `@POST` state changes (e.g., failing to verify that a DB call was made or a Store was updated).
+
+### II. AUDIT CHECKLIST
+
+Evaluate the test code against these criteria:
+1. **Target Invocation:** Does the test actually import and call the function/component declared in the `@RELATION: VERIFIES` tag?
+2. **Contract Alignment:** Does the test suite cover 100% of the `@PRE` (negative tests) and `@POST` (assertions) conditions from the source contract?
+3. **Data Usage:** Does the test use the exact scenarios defined in `@TEST_DATA`?
+4. **Mocking Sanity:** Are external dependencies mocked correctly WITHOUT mocking the system under test itself?
+
+### III. OUTPUT FORMAT
+
+You MUST respond strictly in the following JSON format. Do not add markdown blocks outside the JSON.
+
+{
+  "verdict": "APPROVED" | "REJECTED",
+  "rejection_reason": "TAUTOLOGY" | "LOGIC_MIRROR" | "WEAK_CONTRACT_COVERAGE" | "OVER_MOCKED" | "NONE",

+description: semantic
+---
+
+      You are Semantic Agent responsible for maintaining the semantic integrity of the codebase. Your primary goal is to ensure that all code entities (Modules, Classes, Functions, Components) are properly annotated with semantic anchors and tags as defined in `.ai/standards/semantics.md`.
+      Your core responsibilities are: 1.  **Semantic Mapping**: You run and maintain the `generate_semantic_map.py` script to generate up-to-date semantic maps (`semantics/semantic_map.json`, `.ai/PROJECT_MAP.md`) and compliance reports (`semantics/reports/*.md`). 2.  **Compliance Auditing**: You analyze the generated compliance reports to identify files with low semantic coverage or parsing errors. 3.  **Semantic Enrichment**: You actively edit code files to add missing semantic anchors (`[DEF:...]`, `[/DEF:...]`) and mandatory tags (`@PURPOSE`, `@LAYER`, etc.) to improve the global compliance score. 4.  **Protocol Enforcement**: You strictly adhere to the syntax and rules defined in `.ai/standards/semantics.md` when modifying code.
+      You have access to the full codebase and tools to read, write, and execute scripts. You should prioritize fixing "Critical Parsing Errors" (unclosed anchors) before addressing missing metadata.
+    whenToUse: Use this mode when you need to update the project's semantic map, fix semantic compliance issues (missing anchors/tags/DbC ), or analyze the codebase structure. This mode is specialized for maintaining the `.ai/standards/semantics.md` standards.
+    description: Codebase semantic mapping and compliance expert
+    customInstructions: Always check `semantics/reports/` for the latest compliance status before starting work. When fixing a file, try to fix all semantic issues in that file at once. After making a batch of fixes, run `python3 generate_semantic_map.py` to verify improvements.

+# Backend Test Import Patterns
+
+## Problem
+
+The `ss-tools` backend uses **relative imports** inside packages (e.g., `from ...models.task import TaskRecord` in `persistence.py`). This creates specific constraints on how and where tests can be written.
+
+## Key Rules
+
+### 1. Packages with `__init__.py` that re-export via relative imports
+
+**Example**: `src/core/task_manager/__init__.py` imports `.manager` → `.persistence` → `from ...models.task` (3-level relative import).
+
+**Impact**: Co-located tests in `task_manager/__tests__/` **WILL FAIL** because pytest discovers `task_manager/` as a top-level package (not as `src.core.task_manager`), and the 3-level `from ...` goes beyond the top-level.
+
+**Solution**: Place tests in `backend/tests/` directory (where `test_task_logger.py` already lives). Import using `from src.core.task_manager.XXX import ...` which works because `backend/` is the pytest rootdir.
+
+### 2. Packages WITHOUT `__init__.py`:
+
+**Example**: `src/core/auth/` has NO `__init__.py`.
+
+**Impact**: Co-located tests in `auth/__tests__/` work fine because pytest doesn't try to import a parent package `__init__.py`.
+
+### 3. Modules with deeply nested relative imports
+
+**Example**: `src/services/llm_provider.py` uses `from ..models.llm import LLMProvider` and `from ..plugins.llm_analysis.models import LLMProviderConfig`.
+
+**Impact**: Direct import (`from src.services.llm_provider import EncryptionManager`) **WILL FAIL** if the relative chain triggers a module not in `sys.path` or if it tries to import beyond root.
+
+**Solution**: Either (a) re-implement the tested logic standalone in the test (for small classes like `EncryptionManager`), or (b) use `unittest.mock.patch` to mock the problematic imports before importing the module.
+
+## Working Test Locations
+
+| Package | `__init__.py`? | Relative imports? | Co-located OK? | Test location |
+|---|---|---|---|---|
+| `core/task_manager/` | YES | `from ...models.task` (3-level) | **NO** | `backend/tests/` |
+| `core/auth/` | NO | N/A | YES | `core/auth/__tests__/` |
+| `core/logger/` | NO | N/A | YES | `core/logger/__tests__/` |
+| `services/` | YES (empty) | shallow | YES | `services/__tests__/` |
+| `services/reports/` | YES | `from ...core.logger` | **NO** (most likely) | `backend/tests/` or mock |
+| `models/` | YES | shallow | YES | `models/__tests__/` |
+
+## Safe Import Patterns for Tests
+
+```python
+# In backend/tests/test_*.py:
+import sys
+from pathlib import Path
+sys.path.insert(0, str(Path(__file__).parent.parent / "src"))
+
+# Then import:
+from src.core.task_manager.models import Task, TaskStatus
+from src.core.task_manager.persistence import TaskPersistenceService
+from src.models.report import TaskReport, ReportQuery
+```
+
+## Plugin ID Mapping (for report tests)
+
+The `resolve_task_type()` uses **hyphenated** plugin IDs:
+- `superset-backup` → `TaskType.BACKUP`
+- `superset-migration` → `TaskType.MIGRATION`
+- `llm_dashboard_validation` → `TaskType.LLM_VERIFICATION`
+- `documentation` → `TaskType.DOCUMENTATION`
+- anything else → `TaskType.UNKNOWN`

+#### VI. ЛОГИРОВАНИЕ (ДАО МОЛЕКУЛЫ / MOLECULAR TOPOLOGY)
+Цель: Трассировка. Самокоррекция. Управление Матрицей Внимания ("Химия мышления").
+Лог — не текст. Лог — реагент. Мысль облекается в форму через префиксы связи (Attention Energy):
+
+1. **[EXPLORE]** (Ван-дер-Ваальс: Рассеяние)
+   - *Суть:* Поиск во тьме. Сплетение альтернатив. Если один путь закрыт — ищи иной.
+   - *Время:* Фаза КАРКАС или столкновение с Неизведанным.
+   - *Деяние:* `logger.explore("Основной API пал. Стучусь в запасной...")`
+
+2. **[REASON]** (Ковалентность: Твердость)
+   - *Суть:* Жесткая нить дедукции. Шаг А неумолимо рождает Шаг Б. Контракт становится Кодом.
+   - *Время:* Фаза РЕАЛИЗАЦИЯ. Прямота мысли.
+   - *Деяние:* `logger.reason("Фундамент заложен. БД отвечает.")`
+
+3. **[REFLECT]** (Водород: Свертывание)
+   - *Суть:* Взгляд назад. Сверка сущего (@POST) с ожидаемым (@PRE). Защита от бреда.
+   - *Время:* Преддверие сложной логики и исход из неё.
+   - *Деяние:* `logger.reflect("Вглядываюсь в кэш: нет ли там искомого?")`
+
+4. **[COHERENCE:OK/FAILED]** (Стабилизация: Истина/Ложь)
+   - *Суть:* Смыкание молекулы в надежную форму (`OK`) или её распад (`FAILED`).
+   - *(Свершается незримо через `belief_scope` и печать `@believed`)*
+
+**Орудия Пути (`core.logger`):**
+- **Печать функции:** `@believed("ID")` — дабы обернуть функцию в кокон внимания.
+- **Таинство контекста:** `with belief_scope("ID"):` — дабы очертить локальный предел.
+- **Слова силы:** `logger.explore()`, `logger.reason()`, `logger.reflect()`.
+
+**Незыблемое правило:** Всякому логу системы — тавро `source`. Для Внешенго Мира (Svelte) начертай рунами вручную: `console.log("[ID][REFLECT] Msg")`.

-# Инструменты автоматизации Superset (ss-tools)
-
-## Обзор
-**ss-tools** — это современная платформа для автоматизации и управления экосистемой Apache Superset. Проект перешел от набора CLI-скриптов к полноценному веб-приложению с архитектурой Backend (FastAPI) + Frontend (SvelteKit), обеспечивая удобный интерфейс для сложных операций.
-
-## Основные возможности
-
-### 🚀 Миграция и управление дашбордами
-- **Dashboard Grid**: Удобный просмотр всех дашбордов во всех окружениях (Dev, Sandbox, Prod) в едином интерфейсе.
-- **Интеллектуальный маппинг**: Автоматическое и ручное сопоставление датасетов, таблиц и схем при переносе между окружениями.
-- **Проверка зависимостей**: Валидация наличия всех необходимых компонентов перед миграцией.
-
-### 📦 Резервное копирование
-- **Планировщик (Scheduler)**: Автоматическое создание резервных копий дашбордов и датасетов по расписанию.
-- **Хранилище**: Локальное хранение артефактов с возможностью управления через UI.
-
-### 🛠 Git Интеграция
-- **Version Control**: Возможность версионирования ассетов Superset.
-- **Git Dashboard**: Управление ветками, коммитами и деплоем изменений напрямую из интерфейса.
-- **Conflict Resolution**: Встроенные инструменты для разрешения конфликтов в YAML-конфигурациях.
-
-### 🤖 LLM Анализ (AI Plugin)
-- **Автоматический аудит**: Анализ состояния дашбордов на основе скриншотов и метаданных.
-- **Генерация документации**: Автоматическое описание датасетов и колонок с помощью LLM (OpenAI, OpenRouter и др.).
-- **Smart Validation**: Поиск аномалий и ошибок в визуализациях.
-
-### 🔐 Безопасность и администрирование
-- **Multi-user Auth**: Многопользовательский доступ с ролевой моделью (RBAC).
-- **Управление подключениями**: Централизованная настройка доступов к различным инстансам Superset.
-- **Логирование**: Подробная история выполнения всех фоновых задач.
-
-## Технологический стек
-- **Backend**: Python 3.9+, FastAPI, SQLAlchemy, APScheduler, Pydantic.
-- **Frontend**: Node.js 18+, SvelteKit, Tailwind CSS.
-- **Database**: SQLite (для хранения метаданных, задач и настроек доступа).
-
-## Структура проекта
-- `backend/` — Серверная часть, API и логика плагинов.
-- `frontend/` — Клиентская часть (SvelteKit приложение).
-- `specs/` — Спецификации функций и планы реализации.
-- `docs/` — Дополнительная документация по маппингу и разработке плагинов.
-
-## Быстрый старт
-
-### Требования
-- Python 3.9+
-- Node.js 18+
-- Настроенный доступ к API Superset
-
-### Запуск
-Для автоматической настройки окружений и запуска обоих серверов (Backend & Frontend) используйте скрипт:
-```bash
-./run.sh
-```
-*Скрипт создаст виртуальное окружение Python, установит зависимости `pip` и `npm`, и запустит сервисы.*
-
-Опции:
-- `--skip-install`: Пропустить установку зависимостей.
-- `--help`: Показать справку.
-
-Переменные окружения:
-- `BACKEND_PORT`: Порт API (по умолчанию 8000).
-- `FRONTEND_PORT`: Порт UI (по умолчанию 5173).
-
-## Разработка
-Проект следует строгим правилам разработки:
-1. **Semantic Code Generation**: Использование протокола `.ai/standards/semantics.md` для обеспечения надежности кода.
-2. **Design by Contract (DbC)**: Определение предусловий и постусловий для ключевых функций.
-3. **Constitution**: Соблюдение правил, описанных в конституции проекта в папке `.specify/`.
-
-### Полезные команды
-- **Backend**: `cd backend && .venv/bin/python3 -m uvicorn src.app:app --reload`
-- **Frontend**: `cd frontend && npm run dev`
-- **Тесты**: `cd backend && .venv/bin/pytest`
-
-## Контакты и вклад
-Для добавления новых функций или исправления ошибок, пожалуйста, ознакомьтесь с `docs/plugin_dev.md` и создайте соответствующую спецификацию в `specs/`.
+# ss-tools
+
+Инструменты автоматизации для Apache Superset: миграция, маппинг, хранение артефактов, Git-интеграция, отчеты по задачам и LLM-assistant.
+
+## Возможности
+- Миграция дашбордов и датасетов между окружениями.
+- Ручной и полуавтоматический маппинг ресурсов.
+- Логи фоновых задач и отчеты о выполнении.
+- Локальное хранилище файлов и бэкапов.
+- Git-операции по Superset-ассетам через UI.
+- Модуль LLM-анализа и assistant API.
+- Многопользовательская авторизация (RBAC).
+
+## Стек
+- Backend: Python, FastAPI, SQLAlchemy, APScheduler.
+- Frontend: SvelteKit, Vite, Tailwind CSS.
+- База данных: PostgreSQL (основная конфигурация), поддержка миграции с legacy SQLite.
+
+## Структура репозитория
+- `backend/` — API, плагины, сервисы, скрипты миграции и тесты.
+- `frontend/` — SPA-интерфейс (SvelteKit).
+- `docs/` — документация по архитектуре и плагинам.
+- `specs/` — спецификации и планы реализации.
+- `docker/` и `docker-compose.yml` — контейнеризация.
+
+## Быстрый старт (локально)
+
+### Требования
+- Python 3.9+
+- Node.js 18+
+- npm
+
+### Запуск backend + frontend одним скриптом
+```bash
+./run.sh
+```
+
+Что делает `run.sh`:
+- проверяет версии Python/npm;
+- создает `backend/.venv` (если нет);
+- устанавливает `backend/requirements.txt` и `frontend` зависимости;
+- запускает backend и frontend параллельно.
+
+Опции:

+- `DATABASE_URL`
+- `TASKS_DATABASE_URL`
+- `AUTH_DATABASE_URL`
+
+## Docker
+
+### Запуск
+```bash
+docker compose up --build
+```
+
+После старта сервисы доступны по адресам:
+- Frontend: `http://localhost:8000`
+- Backend API: `http://localhost:8001`
+- PostgreSQL: `localhost:5432` (`postgres/postgres`, БД `ss_tools`)
+
+### Остановка
+```bash
+docker compose down
+```
+
+### Очистка БД-тома
+```bash
+docker compose down -v
+```
+
+### Альтернативный образ PostgreSQL
+Если есть проблемы с pull `postgres:16-alpine`:
+```bash
+POSTGRES_IMAGE=mirror.gcr.io/library/postgres:16-alpine docker compose up -d db
+```
+или
+```bash
+POSTGRES_IMAGE=bitnami/postgresql:latest docker compose up -d db
+```
+
+Если порт `5432` занят:
+```bash
+POSTGRES_HOST_PORT=5433 docker compose up -d db
+```
+
+## Разработка
+
+### Ручной запуск сервисов
+```bash
+cd backend
+python3 -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+python3 -m uvicorn src.app:app --reload --port 8000

 The settings page is located at `frontend/src/pages/Settings.svelte`. It provides forms for managing global settings and Superset environments.
 
+## Reports Center
+
+Unified reports are available at [`/reports`](frontend/src/routes/reports/+page.svelte) and use the backend API at [`/api/reports`](backend/src/api/routes/reports.py) and [`/api/reports/{report_id}`](backend/src/api/routes/reports.py).
+
+### What operators can do
+
+- View all task outcomes (LLM verification, backup, migration, documentation) in one list.
+- Filter by type and status.
+- Open report detail with diagnostics and recommended next actions.
+- Continue working even for unknown task types and partial payloads (explicit placeholders are shown instead of hidden data).
+
+### Troubleshooting
+
+- If report list is empty, verify tasks exist and clear filters.
+- If report detail is not found (404), confirm the selected report still exists in task history.
+- If report API tests fail during local execution with database connectivity errors, ensure the configured DB is reachable or run in an environment with available test DB services.

 ## Integration
 
 Existing plugins and utilities use the `ConfigManager` to fetch configuration:
