-# Архитектурное решение: Standalone сервис vs Интеграция в Superset
-
-## Рекомендация: Оставить отдельным сервисом
-
-Хотя интеграция непосредственно в Superset может показаться привлекательной для создания "единого интерфейса", **настоятельно рекомендуется оставить `ss-tools` отдельным сервисом** по следующим архитектурным и техническим причинам.
-
-### 1. Архитектурный паттерн: Оркестратор против Инстанса
-*   **Проблема:** `ss-tools` действует как **"Менеджер менеджеров"**. Его основная ценность заключается в подключении и перемещении данных *между* различными окружениями Superset (Dev → Stage → Prod).
-*   **Почему разделение лучше:** Если встроить эту логику в Superset, придется сделать один конкретный инстанс (например, "Dev") "главным контроллером" для остальных. Если этот инстанс упадет, вы потеряете возможности управления. Отдельный инструмент находится *над* окружениями, рассматривая их все как равные endpoints.
-
-### 2. Несовместимость технологического стека
-*   **Superset:** Бэкенд на **Flask** (Python) с фронтендом на **React**.
-*   **ss-tools:** Бэкенд на **FastAPI** (Python) с фронтендом на **SvelteKit**.
-*   **Цена миграции:** Перенос в Superset потребует **полного переписывания** всего фронтенда с Svelte на React, чтобы он мог работать как плагин или расширение Superset. Также потребуется рефакторинг внедрения зависимостей (Dependency Injection) из FastAPI, чтобы соответствовать структуре Flask-AppBuilder в Superset.
-
-### 3. Цикл релизов и гибкость
-*   **Superset:** Имеет сложный и медленный цикл релизов. Внедрение кастомных фич в основной репозиторий (upstream) затруднительно, а поддержка собственного "форка" Superset — это кошмар сопровождения (конфликты слияния при каждом обновлении).
-*   **ss-tools:** Как отдельный микросервис, вы можете развертывать новые функции (например, новые LLM плагины или Git-процессы) мгновенно, не беспокоясь о том, что сломаете основную BI-платформу.
-
-### 4. Безопасность и изоляция
-*   **Права доступа:** `ss-tools` имеет свои собственные страницы администрирования (`AdminRolesPage` и `AdminUsersPage`), управляющие правами специально для задач *деплоя* и *резервного копирования*. Это задачи DevOps, а не бизнес-аналитики (BI). Смешивание привилегий развертывания с привилегиями просмотра данных в одной системе увеличивает "радиус поражения" в случае проблем с безопасностью.
-
-### Техническая реализуемость (если все же решиться)
-Это технически возможно, но процесс будет выглядеть так:
-1.  **Frontend:** Придется переписать все компоненты Svelte (`DashboardGrid`, `MappingTable` и т.д.) как компоненты React, чтобы они могли жить внутри `superset-frontend`.
-2.  **Backend:** Вероятно, придется реализовать это как серверное **расширение Superset** (используя Flask Blueprints), создав новые API endpoints, которые будет вызывать фронтенд на React.
-3.  **Database:** Придется добавить таблицы проекта (`task_records`, `connection_configs`) в базу данных метаданных Superset через миграции Alembic.
-
-### Итоговая таблица
-
-| Характеристика | Отдельный сервис (Текущий) | Интеграция в Superset |
-| :--- | :--- | :--- |
-| **Скорость разработки** | 🚀 Высокая (Независимая) | 🐢 Низкая (Связана с монолитом) |
-| **Технологический стек** | Современный (FastAPI + SvelteKit) | Legacy/Строгий (Flask + React) |
-| **Управление мульти-окружением** | ✅ Нативно (Спроектирован для этого) | ⚠️ Неудобно (Один инстанс управляет всеми) |
-| **Поддержка (Maintenance)** | ✅ Низкая (Обновление в любое время) | ❌ Высокая (Rebase при каждом обновлении Superset) |
-
-**Вывод:** Проект уже хорошо спроектирован как специализированный инструмент DevOps (слой `DevOps/Tooling` в вашей семантической карте). Слияние его с Superset, скорее всего, приведет к техническому долгу и регрессии функциональности.

-## 4. Logging with TaskContext
+## 4. Logging
 
-Plugins now support TaskContext for structured logging with source attribution. The `context` parameter provides access to a logger that automatically tags logs with the task ID and a source identifier.
-
-### 4.1. Basic Logging
-
-Use `context.logger` to log messages with automatic source attribution:
+You can use the global logger instance to log messages from your plugin. The logger is available in the `superset_tool.utils.logger` module.
 
 ```python
-from typing import Dict, Any, Optional
-from ..core.plugin_base import PluginBase
-from ..core.task_manager.context import TaskContext
+from superset_tool.utils.logger import SupersetLogger
 
-async def execute(self, params: Dict[str, Any], context: Optional[TaskContext] = None):
-    if context:
-        # Use TaskContext logger for structured logging
-        context.logger.info("My plugin is running!")
-    else:
-        # Fallback to global logger for backward compatibility
-        from ..core.logger import logger
-        logger.info("My plugin is running!")
+logger = SupersetLogger()
+
+async def execute(self, params: Dict[str, Any]):
+    logger.info("My plugin is running!")
 ```
 
-### 4.2. Source Attribution
-
-For better log organization, create sub-loggers for different components:
-
-```python
-async def execute(self, params: Dict[str, Any], context: Optional[TaskContext] = None):
-    if context:
-        # Create sub-loggers for different components
-        api_log = context.logger.with_source("api")
-        storage_log = context.logger.with_source("storage")
-        
-        api_log.info("Connecting to API...")
-        storage_log.info("Saving file...")
-    else:
-        # Fallback to global logger
-        from ..core.logger import logger
-        logger.info("My plugin is running!")
-```
-
-### 4.3. Log Levels
-
-The logger supports standard log levels. Use them appropriately:
-
-| Level | Usage |
-|-------|-------|
-| `DEBUG` | Detailed diagnostic information (API responses, internal state). Only visible when log level is set to DEBUG. |
-| `INFO` | General operational messages (start/complete notifications, progress updates). |
-| `WARNING` | Non-critical issues that don't stop execution (deprecated APIs, retry attempts). |
-| `ERROR` | Failures that prevent an operation from completing (API errors, validation failures). |
-
-```python
-# Good: Use DEBUG for verbose diagnostic info
-api_log.debug(f"API response: {response.json()}")
-
-# Good: Use INFO for operational milestones
-log.info(f"Starting backup for environment: {env}")
-
-# Good: Use WARNING for recoverable issues
-log.warning(f"Rate limit hit, retrying in {delay}s")
-
-# Good: Use ERROR for failures
-log.error(f"Failed to connect to database: {e}")
-```
-
-### 4.4. Progress Logging
-
-For operations that report progress, use the `progress` method:
-
-```python
-async def execute(self, params: Dict[str, Any], context: Optional[TaskContext] = None):
-    if context:
-        total_items = 100
-        for i, item in enumerate(items):
-            # Report progress with percentage
-            percent = (i + 1) / total_items * 100
-            context.logger.progress(f"Processing {item}", percent=percent)
-    else:
-        # Fallback
-        from ..core.logger import logger
-        logger.info("My plugin is running!")
-```
-
-### 4.5. Logging with Metadata
-
-You can include structured metadata with log entries:
-
-```python
-async def execute(self, params: Dict[str, Any], context: Optional[TaskContext] = None):
-    if context:
-        context.logger.error(
-            "Operation failed",
-            metadata={"error_code": 500, "details": "Connection timeout"}
-        )
-    else:
-        from ..core.logger import logger
-        logger.error("Operation failed")
-```
-
-### 4.6. Common Source Names
-
-For consistency across plugins, use these standard source names:
-
-| Source | Usage |
-|--------|-------|
-| `superset_api` | Superset REST API calls |
-| `postgres` | PostgreSQL database operations |
-| `storage` | File system operations |
-| `git` | Git operations |
-| `llm` | LLM API calls |
-| `screenshot` | Screenshot capture operations |
-| `migration` | Migration-specific logic |
-| `backup` | Backup operations |
-| `debug` | Debug/diagnostic operations |
-| `search` | Search operations |
-
-### 4.7. Best Practices
-
-1. **Always check for context**: Support backward compatibility by checking if `context` is available:
-   ```python
-   log = context.logger if context else logger
-   ```
-
-2. **Use source attribution**: Create sub-loggers for different components to make filtering easier in the UI.
-
-3. **Use appropriate log levels**:
-   - `DEBUG`: Verbose diagnostic info (API responses, internal state)
-   - `INFO`: Operational milestones (start, complete, progress)
-   - `WARNING`: Recoverable issues (rate limits, deprecated APIs)
-   - `ERROR`: Failures that stop an operation
-
-4. **Log progress for long operations**: Use `progress()` for operations that take time:
-   ```python
-   for i, item in enumerate(items):
-       percent = (i + 1) / len(items) * 100
-       log.progress(f"Processing {item}", percent=percent)
-   ```
-
-5. **Keep DEBUG logs verbose, INFO logs concise**: DEBUG logs can include full API responses, while INFO logs should be one-line summaries.
-
 ## 5. Testing
 
 To test your plugin, simply run the application and navigate to the web UI. Your plugin should appear in the list of available tools.

 **Constraints**: Must integrate with existing `PluginBase` and `TaskManager`. Secure storage for API keys.
 **Scale/Scope**: Support for configurable LLM providers, scheduled tasks, and notification integration.
 
-## Implementation Notes
-
-### Screenshot Capture Implementation
-The screenshot service uses Playwright with Chrome DevTools Protocol (CDP) to avoid font loading timeouts in headless mode. Key implementation details:
-- **Full Page Capture**: Uses CDP `Page.captureScreenshot` with `captureBeyondViewport: true` and `fromSurface: true`
-- **Tab Switching**: Implements recursive tab switching to trigger lazy-loaded chart rendering on multi-tab dashboards
-- **Authentication**: Uses direct UI login flow (navigating to `/login/` and filling credentials) instead of API cookie injection for better reliability
-- **Resolution**: 1920px width with dynamic full page height calculation
-
-### Authentication Flow
-The service authenticates via Playwright UI login rather than API authentication:
-1. Navigate to `/login/` page
-2. Fill username/password fields (supports multiple Superset versions)
-3. Click login button
-4. Verify successful redirect to `/superset/welcome/`
-5. Navigate to dashboard with valid session
-
-This approach is more reliable than API-to-UI cookie injection which was causing 403 Forbidden errors.

-## 2. Database Schema
-
-A new table `task_logs` will be added to the primary database.
-
-| Column | Type | Constraints |
-|--------|------|-------------|
-| `id` | Integer | Primary Key, Autoincrement |
-| `task_id` | String | Foreign Key (tasks.id), Indexed |
-| `timestamp` | DateTime | Not Null, Indexed |
-| `level` | String(16) | Not Null (INFO, WARNING, ERROR, DEBUG) |
-| `source` | String(64) | Not Null, Default: 'system' |
-| `message` | Text | Not Null |
-| `metadata_json` | Text | Nullable (JSON string) |
-
-## 3. Backend Implementation Details
-
-### 3.1. `TaskLogger` & `TaskContext`
-- `TaskLogger`: A wrapper around `TaskManager._add_log` that carries `task_id` and `source`.
-- `TaskContext`: A container passed to `plugin.execute()` providing the logger and other task-specific utilities.
-
-### 3.2. `TaskManager` Enhancements
-- **Log Buffer**: A dictionary mapping `task_id` to a list of pending `LogEntry` objects.
-- **Flusher Thread**: A background daemon thread that flushes the buffer to the database every 2 seconds.
-- **Backward Compatibility**: Use `inspect.signature` to detect if a plugin's `execute` method accepts the new `context` parameter.
-
-### 3.3. API Endpoints
-- `GET /api/tasks/{task_id}/logs`: Supports `level`, `source`, `search`, `offset`, and `limit`.
-- `GET /api/tasks/{task_id}/logs/stats`: Returns counts by level and source.
-- `GET /api/tasks/{task_id}/logs/sources`: Returns unique sources for the task.
-
-## 4. Frontend Implementation Details
-
-### 4.1. Components
-- `TaskLogPanel`: Main container managing state and data fetching.
-- `LogFilterBar`: UI for selecting filters.
-- `LogEntryRow`: Optimized row rendering with color coding and progress bar support.
-
-### 4.2. Data Fetching
-- **Live Tasks**: Connect via WebSocket with filter parameters in the query string.
-- **Completed Tasks**: Fetch via REST API with pagination.
-
-## 5. Implementation Phases
-
-### Phase 1: Foundation
-- Database migration (new table).
-- `LogPersistenceService` implementation.
-- `TaskLogger` and `TaskContext` classes.
-
-### Phase 2: Core Integration
-- `TaskManager` buffer and flusher logic.
-- API endpoint updates.
-- WebSocket server-side filtering.
-
-### Phase 3: Plugin Migration
-- Update core plugins (Backup, Migration, Git) to use the new logger.
-- Verify backward compatibility with un-migrated plugins.
-
-### Phase 4: Frontend
-- Implement new Svelte components.
-- Integrate with updated API and WebSocket.
-
-## 6. Verification Plan
-
-- **Unit Tests**:
-    - `TaskLogger` correctly routes to `TaskManager`.
-    - `LogPersistenceService` handles batch inserts and complex filters.
-    - `TaskManager` flushes logs on task completion.
-- **Integration Tests**:
-    - End-to-end flow from plugin log to frontend display.
-    - Verification of log persistence after server restart.
-- **Performance Tests**:
-    - Measure overhead of batch logging under high load (1000+ logs/sec).

-# Feature Specification: Task Logging System (Separated Per-Task Logs)
-
-**Feature Branch**: `018-task-logging-v2`  
-**Reference UX**: `specs/018-task-logging-v2/ux_reference.md`
-**Created**: 2026-02-07  
-**Status**: Draft  
-**Input**: User description: "Implement a separated per-task logging system with source attribution, persistence, and frontend filtering."
-
-## User Scenarios & Testing *(mandatory)*
-
-### User Story 1 - Real-time Filtered Logging (Priority: P1)
-
-As a user, I want to see logs from a running task filtered by their source so that I can focus on specific component behavior without noise.
-
-**Why this priority**: This is the core value proposition—isolating component logs during execution.
-
-**Independent Test**: Start a task that emits logs from multiple sources (e.g., `plugin` and `system`), apply a source filter in the UI, and verify only matching logs are displayed in real-time.
-
-**Acceptance Scenarios**:
-
-1. **Given** a task is running and emitting logs from "plugin" and "superset_api", **When** I select "superset_api" in the Source filter, **Then** only logs with the "superset_api" tag are visible.
-2. **Given** a filter is active, **When** a new log matching the filter arrives via WebSocket, **Then** it is immediately appended to the view.
-
----
-
-### User Story 2 - Persistent Log History (Priority: P1)
-
-As a user, I want my task logs to be saved permanently so that I can review them even after the server restarts.
-
-**Why this priority**: Current logs are in-memory and lost on restart, which is a major pain point for debugging past failures.
-
-**Independent Test**: Run a task, restart the backend server, and verify that the logs for that task are still accessible via the UI.
-
-**Acceptance Scenarios**:
-
-1. **Given** a task has completed, **When** I restart the server and navigate to the task details, **Then** all logs are loaded from the database.
-2. **Given** a task was deleted via the cleanup service, **When** I check the database, **Then** all associated logs are also removed.
-
----
-
-### User Story 3 - Component Attribution (Priority: P2)
-
-As a developer, I want to use a dedicated logger that automatically tags my logs with the correct source.
-
-**Why this priority**: Simplifies plugin development and ensures consistent data for filtering.
-
-**Independent Test**: Update a plugin to use `context.logger.with_source("custom")` and verify that logs appear with the "custom" tag.
-
-**Acceptance Scenarios**:
-
-1. **Given** a plugin uses the new `TaskContext`, **When** it calls `logger.info()`, **Then** the log is recorded with `source="plugin"` by default.
-2. **Given** a plugin creates a sub-logger with `with_source("api")`, **When** it logs a message, **Then** the log is recorded with `source="api"`.
-
----
-
-### User Story 4 - Configurable Logging Levels (Priority: P1)
-
-As an admin, I want to configure logging levels through the frontend so that I can control verbosity and filter noise during debugging.
-
-**Why this priority**: Essential for production debugging and performance tuning.
-
-**Independent Test**: Change the log level from INFO to DEBUG in admin settings, run a task, and verify that DEBUG-level logs (including belief_scope) now appear.
-
-**Acceptance Scenarios**:
-
-1. **Given** I am an admin user, **When** I navigate to Admin Settings > Logging, **Then** I see options for log level, task log level, and belief_scope toggle.
-2. **Given** belief_scope logging is enabled, **When** I set log level to DEBUG, **Then** all belief_scope Entry/Exit/Coherence logs are visible.
-3. **Given** belief_scope logging is enabled, **When** I set log level to INFO, **Then** belief_scope logs are hidden (they are DEBUG level).
-4. **Given** I set task_log_level to WARNING, **When** a task runs, **Then** only WARNING and ERROR logs are persisted for that task.
-
----
-
-### Edge Cases
-
-- **High Volume Logs**: How does the system handle a task generating 10,000+ logs in a few seconds? (Requirement: Batching and virtual scrolling).
-- **Database Connection Loss**: What happens if the log flusher cannot write to the DB? (Requirement: Logs should remain in-memory as a fallback until the next flush).
-- **Concurrent Tasks**: Ensure logs from Task A never leak into the view or database records of Task B.
-
-## Requirements *(mandatory)*
-
-### Functional Requirements
-
-- **FR-001**: System MUST persist task logs in a dedicated `task_logs` database table.
-- **FR-002**: Each log entry MUST include: `task_id`, `timestamp`, `level`, `message`, `source`, and optional `metadata`.
-- **FR-003**: System MUST provide a `TaskLogger` via a `TaskContext` to all plugins.
-- **FR-004**: System MUST support batch-writing logs to the database (e.g., every 2 seconds) to maintain performance.
-- **FR-005**: Backend MUST support server-side filtering of logs by `level`, `source`, and text `search` via REST and WebSocket.
-- **FR-006**: Frontend MUST provide a UI for filtering and searching logs within the task details view.
-- **FR-007**: System MUST maintain backward compatibility for plugins using the old `execute` signature.
-- **FR-008**: System MUST automatically delete logs when their associated task is deleted.
-- **FR-009**: Task logs MUST follow the same retention policy as task records (logs are kept as long as the task record exists).
-- **FR-010**: The default log level filter in the UI MUST be set to INFO and above (hiding DEBUG logs by default).
-- **FR-011**: System MUST support filtering logs by specific keys within the `metadata` JSON (e.g., `dashboard_id`, `database_uuid`).
-- **FR-012**: System MUST separate log levels clearly: DEBUG (development/tracing), INFO (normal operations), WARNING (potential issues), ERROR (failures).
-- **FR-013**: `belief_scope` context manager MUST log at DEBUG level (not INFO) to reduce noise in production.
-- **FR-014**: Admin users MUST be able to configure logging levels through the frontend settings UI.
-- **FR-015**: System MUST support separate log level configuration for application logs vs task-specific logs.
-- **FR-016**: All plugins MUST support `TaskContext` for proper source attribution and log level filtering.
-
-## Clarifications
-
-### Session 2026-02-07
-- Q: Should task logs follow the same retention period as the task records themselves? → A: Same as Task Records.
-- Q: What should be the default log level filter when a user opens the task log panel? → A: INFO and above.
-- Q: Do we need to support searching or filtering inside the JSON metadata? → A: Searchable keys (e.g., `dashboard_id` should be filterable).
-
-### Key Entities *(include if feature involves data)*
-
-- **TaskLog**: Represents a single log message.
-    - Attributes: `id` (PK), `task_id` (FK), `timestamp`, `level` (Enum/String), `source` (String), `message` (Text), `metadata` (JSON).
-- **TaskContext**: Execution context provided to plugins.
-    - Attributes: `task_id`, `logger`, `config`.
-
-## Success Criteria *(mandatory)*
-
-### Measurable Outcomes
-
-- **SC-001**: Log retrieval for a task with 1,000 entries takes less than 200ms.
-- **SC-002**: Database write overhead for logging does not increase task execution time by more than 5%.
-- **SC-003**: 100% of logs generated by a task are available after a server restart.
-- **SC-004**: Users can filter logs by source and see results in under 100ms on the frontend.
-- **SC-005**: Admin users can change logging levels via frontend UI without server restart.
-- **SC-006**: All plugins use TaskContext for logging with proper source attribution.

-## Dependencies & Execution Order
-
-### Phase Dependencies
-
-- **Setup (Phase 1)**: No dependencies.
-- **Foundational (Phase 2)**: Depends on Phase 1.
-- **User Stories (Phase 3-5)**: Depend on Phase 2. US2 (Persistence) is prioritized as it's the foundation for historical logs.
-- **Polish (Phase 6)**: Depends on all user stories.
-
-### Parallel Opportunities
-
-- T002, T003, T004 can run in parallel.
-- T010, T011 can run in parallel.
-- T016, T017 can run in parallel.
-- Plugin migrations (T022-T024) can run in parallel.
-
----
-
-## Implementation Strategy
-
-### MVP First (User Story 2)
-
-1. Complete Setup & Foundational phases.
-2. Implement US2 (Persistence & API).
-3. **STOP and VALIDATE**: Verify logs are saved and retrieved after restart.
-
-### Incremental Delivery
-
-1. Add US1 (Real-time & UI) → Test filtering.
-2. Add US3 (Plugin Migration) → Test source attribution.
-
----
-
-## Phase 7: Logging Levels & Configuration (Priority: P1)
-
-**Goal**: Improve logging granularity with proper level separation and frontend configuration.
-
-**Purpose**:
-- Explicitly separate log levels (DEBUG, INFO, WARNING, ERROR) across all components
-- Move belief_scope logging to DEBUG level to reduce noise

-# UX Reference: Task Logging System (Separated Per-Task Logs)
-
-**Feature Branch**: `018-task-logging-v2`
-**Created**: 2026-02-07
-**Status**: Draft
-
-## 1. User Persona & Context
-
-*   **Who is the user?**: System Administrator / DevOps Engineer / Developer.
-*   **What is their goal?**: Monitor task execution in real-time, debug failures by isolating logs from specific components (e.g., Superset API vs. Git operations), and review historical logs of completed tasks.
-*   **Context**: Using the web dashboard to run migrations, backups, or LLM analysis.
-
-## 2. The "Happy Path" Narrative
-
-The user starts a migration task and immediately sees the log panel. As the task progresses, logs appear with clear color-coded tags indicating their source (e.g., `[superset_api]`, `[git]`). The user notices a warning from the `superset_api` source, clicks the "Source" filter, and selects "superset_api" to isolate those messages. The view instantly updates to show only API-related logs, allowing the user to quickly identify a rate-limiting warning. Once the task finishes, the user refreshes the page, and the logs are still there, fully searchable and filterable.
-
-## 3. Interface Mockups
-
-### UI Layout & Flow
-
-**Screen/Component**: TaskLogPanel (within Task Details)
-
-*   **Layout**: A header with filter controls, followed by a scrollable log area.
-*   **Key Elements**:
-    *   **Level Filter**: Dropdown (All, Info, Warning, Error, Debug).
-    *   **Source Filter**: Dropdown (All, plugin, superset_api, storage, etc.).
-    *   **Search Input**: Text field with "Search logs..." placeholder.
-    *   **Log Area**: Monospace font, alternating row backgrounds.
-    *   **Progress Bar**: Inline bar appearing within a log row when a component reports progress.
-*   **States**:
-    *   **Default**: Shows all logs for the current task.
-    *   **Filtering**: Log list updates as filters are changed (live for running tasks via WS).
-    *   **Auto-scroll**: Enabled by default; a "Jump to Bottom" button appears if the user scrolls up.
-
-## 4. The "Error" Experience
-
-### Scenario A: Log Loading Failure
-
-*   **User Action**: Opens a historical task with thousands of logs.
-*   **System Response**: A small inline notification: "Failed to load full log history. [Retry]".
-*   **Recovery**: Clicking "Retry" re-triggers the REST API call.
-
-### Scenario B: WebSocket Disconnect
-
-*   **System Response**: The log panel shows a "Reconnecting..." status indicator.
-*   **Recovery**: System automatically reconnects; once back, it fetches missing logs since the last received timestamp.
-
-## 5. Tone & Voice
-
-*   **Style**: Technical, precise, and informative.
-*   **Terminology**: Use "Source" for component identification, "Level" for severity, and "Persistence" for saved logs.
