+# Tasks: [FEATURE NAME]
+
+**Input**: Design documents from `/specs/[###-feature-name]/`
+**Prerequisites**: plan.md (required), spec.md (required for user stories), research.md, data-model.md, contracts/
+
+**Tests**: The examples below include test tasks. Tests are OPTIONAL - only include them if explicitly requested in the feature specification.
+
+**Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story.
+
+## Format: `[ID] [P?] [Story] Description`
+
+- **[P]**: Can run in parallel (different files, no dependencies)
+- **[Story]**: Which user story this task belongs to (e.g., US1, US2, US3)
+- Include exact file paths in descriptions
+
+## Path Conventions
+
+- **Single project**: `src/`, `tests/` at repository root
+- **Web app**: `backend/src/`, `frontend/src/`
+- **Mobile**: `api/src/`, `ios/src/` or `android/src/`
+- Paths shown below assume single project - adjust based on plan.md structure
+
+<!-- 
+  ============================================================================
+  IMPORTANT: The tasks below are SAMPLE TASKS for illustration purposes only.
+  
+  The /speckit.tasks command MUST replace these with actual tasks based on:
+  - User stories from spec.md (with their priorities P1, P2, P3...)
+  - Feature requirements from plan.md
+  - Entities from data-model.md
+  - Endpoints from contracts/
+  
+  Tasks MUST be organized by user story so each story can be:
+  - Implemented independently
+  - Tested independently
+  - Delivered as an MVP increment
+  
+  DO NOT keep these sample tasks in the generated tasks.md file.
+  ============================================================================
+-->
+
+## Phase 1: Setup (Shared Infrastructure)
+
+**Purpose**: Project initialization and basic structure
+
+- [ ] T001 Create project structure per implementation plan
+- [ ] T002 Initialize [language] project with [framework] dependencies
+- [ ] T003 [P] Configure linting and formatting tools
+
+---
+
+## Phase 2: Foundational (Blocking Prerequisites)
+
+**Purpose**: Core infrastructure that MUST be complete before ANY user story can be implemented
+
+**⚠️ CRITICAL**: No user story work can begin until this phase is complete
+
+Examples of foundational tasks (adjust based on your project):
+
+- [ ] T004 Setup database schema and migrations framework
+- [ ] T005 [P] Implement authentication/authorization framework
+- [ ] T006 [P] Setup API routing and middleware structure
+- [ ] T007 Create base models/entities that all stories depend on
+- [ ] T008 Configure error handling and logging infrastructure
+- [ ] T009 Setup environment configuration management
+
+**Checkpoint**: Foundation ready - user story implementation can now begin in parallel
+
+---
+
+## Phase 3: User Story 1 - [Title] (Priority: P1) 🎯 MVP
+
+**Goal**: [Brief description of what this story delivers]
+
+**Independent Test**: [How to verify this story works on its own]
+
+### Tests for User Story 1 (OPTIONAL - only if tests requested) ⚠️
+
+> **NOTE: Write these tests FIRST, ensure they FAIL before implementation**
+
+- [ ] T010 [P] [US1] Contract test for [endpoint] in tests/contract/test_[name].py
+- [ ] T011 [P] [US1] Integration test for [user journey] in tests/integration/test_[name].py
+
+### Implementation for User Story 1
+
+- [ ] T012 [P] [US1] Create [Entity1] model in src/models/[entity1].py
+- [ ] T013 [P] [US1] Create [Entity2] model in src/models/[entity2].py
+- [ ] T014 [US1] Implement [Service] in src/services/[service].py (depends on T012, T013)
+- [ ] T015 [US1] Implement [endpoint/feature] in src/[location]/[file].py
+- [ ] T016 [US1] Add validation and error handling
+- [ ] T017 [US1] Add logging for user story 1 operations
+
+**Checkpoint**: At this point, User Story 1 should be fully functional and testable independently
+
+---
+
+## Phase 4: User Story 2 - [Title] (Priority: P2)
+
+**Goal**: [Brief description of what this story delivers]
+
+**Independent Test**: [How to verify this story works on its own]
+
+### Tests for User Story 2 (OPTIONAL - only if tests requested) ⚠️
+
+- [ ] T018 [P] [US2] Contract test for [endpoint] in tests/contract/test_[name].py
+- [ ] T019 [P] [US2] Integration test for [user journey] in tests/integration/test_[name].py
+
+### Implementation for User Story 2
+
+- [ ] T020 [P] [US2] Create [Entity] model in src/models/[entity].py
+- [ ] T021 [US2] Implement [Service] in src/services/[service].py
+- [ ] T022 [US2] Implement [endpoint/feature] in src/[location]/[file].py
+- [ ] T023 [US2] Integrate with User Story 1 components (if needed)
+
+**Checkpoint**: At this point, User Stories 1 AND 2 should both work independently
+
+---
+
+## Phase 5: User Story 3 - [Title] (Priority: P3)
+
+**Goal**: [Brief description of what this story delivers]
+
+**Independent Test**: [How to verify this story works on its own]
+
+### Tests for User Story 3 (OPTIONAL - only if tests requested) ⚠️
+
+- [ ] T024 [P] [US3] Contract test for [endpoint] in tests/contract/test_[name].py
+- [ ] T025 [P] [US3] Integration test for [user journey] in tests/integration/test_[name].py
+
+### Implementation for User Story 3
+
+- [ ] T026 [P] [US3] Create [Entity] model in src/models/[entity].py
+- [ ] T027 [US3] Implement [Service] in src/services/[service].py
+- [ ] T028 [US3] Implement [endpoint/feature] in src/[location]/[file].py
+
+**Checkpoint**: All user stories should now be independently functional
+
+---
+
+[Add more user story phases as needed, following the same pattern]
+
+---
+
+## Phase N: Polish & Cross-Cutting Concerns
+
+**Purpose**: Improvements that affect multiple user stories
+
+- [ ] TXXX [P] Documentation updates in docs/
+- [ ] TXXX Code cleanup and refactoring
+- [ ] TXXX Performance optimization across all stories
+- [ ] TXXX [P] Additional unit tests (if requested) in tests/unit/
+- [ ] TXXX Security hardening
+- [ ] TXXX Run quickstart.md validation
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: No dependencies - can start immediately
+- **Foundational (Phase 2)**: Depends on Setup completion - BLOCKS all user stories
+- **User Stories (Phase 3+)**: All depend on Foundational phase completion
+  - User stories can then proceed in parallel (if staffed)
+  - Or sequentially in priority order (P1 → P2 → P3)
+- **Polish (Final Phase)**: Depends on all desired user stories being complete
+
+### User Story Dependencies
+
+- **User Story 1 (P1)**: Can start after Foundational (Phase 2) - No dependencies on other stories
+- **User Story 2 (P2)**: Can start after Foundational (Phase 2) - May integrate with US1 but should be independently testable
+- **User Story 3 (P3)**: Can start after Foundational (Phase 2) - May integrate with US1/US2 but should be independently testable
+
+### Within Each User Story
+
+- Tests (if included) MUST be written and FAIL before implementation
+- Models before services
+- Services before endpoints
+- Core implementation before integration
+- Story complete before moving to next priority
+
+### Parallel Opportunities
+
+- All Setup tasks marked [P] can run in parallel
+- All Foundational tasks marked [P] can run in parallel (within Phase 2)
+- Once Foundational phase completes, all user stories can start in parallel (if team capacity allows)
+- All tests for a user story marked [P] can run in parallel
+- Models within a story marked [P] can run in parallel
+- Different user stories can be worked on in parallel by different team members
+
+---
+
+## Parallel Example: User Story 1
+
+```bash
+# Launch all tests for User Story 1 together (if tests requested):
+Task: "Contract test for [endpoint] in tests/contract/test_[name].py"
+Task: "Integration test for [user journey] in tests/integration/test_[name].py"
+
+# Launch all models for User Story 1 together:
+Task: "Create [Entity1] model in src/models/[entity1].py"
+Task: "Create [Entity2] model in src/models/[entity2].py"
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup
+2. Complete Phase 2: Foundational (CRITICAL - blocks all stories)
+3. Complete Phase 3: User Story 1
+4. **STOP and VALIDATE**: Test User Story 1 independently
+5. Deploy/demo if ready
+
+### Incremental Delivery
+
+1. Complete Setup + Foundational → Foundation ready
+2. Add User Story 1 → Test independently → Deploy/Demo (MVP!)
+3. Add User Story 2 → Test independently → Deploy/Demo
+4. Add User Story 3 → Test independently → Deploy/Demo
+5. Each story adds value without breaking previous stories
+
+### Parallel Team Strategy
+
+With multiple developers:
+
+1. Team completes Setup + Foundational together
+2. Once Foundational is done:
+   - Developer A: User Story 1
+   - Developer B: User Story 2
+   - Developer C: User Story 3
+3. Stories complete and integrate independently
+
+---
+
+## Notes
+
+- [P] tasks = different files, no dependencies
+- [Story] label maps task to specific user story for traceability
+- Each user story should be independently completable and testable
+- Verify tests fail before implementing
+- Commit after each task or logical group
+- Stop at any checkpoint to validate story independently
+- Avoid: vague tasks, same file conflicts, cross-story dependencies that break independence

+# Research: Backup Scheduler & Unified Task UI
+
+## Decisions
+
+### 1. Scheduler Implementation
+- **Decision**: Use `APScheduler` (Advanced Python Scheduler) with `BackgroundScheduler`.
+- **Rationale**: `APScheduler` is the industry standard for Python scheduling. It supports Cron-style scheduling (required by FR-001), runs in the background (FR-003), and handles thread management. It integrates well with FastAPI lifecycles.
+- **Alternatives Considered**: 
+    - `cron` (system level): Harder to manage from within the app, requires OS access.
+    - `schedule` library: Simpler but lacks advanced Cron features and persistence robustness.
+    - Custom thread loop: Error-prone and reinvents the wheel.
+
+### 2. Task History Database
+- **Decision**: SQLite (`tasks.db`) accessed via `SQLAlchemy` (AsyncIO).
+- **Rationale**: The spec explicitly requests `tasks.db` (FR-009). SQLAlchemy provides a robust ORM for the `Task` entity. Using AsyncIO ensures non-blocking database operations within the FastAPI event loop, even if the actual backup tasks run in threads.
+- **Alternatives Considered**: 
+    - `JSON` files: Poor performance for filtering/sorting logs (FR-006).
+    - `PostgreSQL`: Overkill for a local tool configuration.
+
+### 3. Concurrency Handling
+- **Decision**: Skip scheduled backups if a backup is already running for the *same* environment. Allow concurrent backups for *different* environments.
+- **Rationale**: Prevents resource contention and potential corruption of the same target.
+- **Implementation**: The `SchedulerService` will check `TaskManager` for active jobs with the same `environment_id` before triggering.
+
+### 4. Frontend Polling vs WebSockets
+- **Decision**: Polling (every 2-5 seconds) for the "Tasks" tab.
+- **Rationale**: Simpler to implement than WebSockets for this scale. The requirement is "near real-time" (SC-002: latency < 5s), which polling satisfies easily.
+- **Alternatives Considered**: 
+    - WebSockets: Better real-time, but higher complexity for connection management and state.

+# Feature Specification: Backup Scheduler & Unified Task UI
+
+**Feature Branch**: `009-backup-scheduler`
+**Created**: 2025-12-30
+**Status**: Draft
+**Input**: User description: "Я хочу доработать механизм бекапа. Он должен иметь возможность работать по расписанию, задания и их статус должны использовать TaskManager и быть доступны в общем логе. Я думаю нужно вынести все задачи в отдельную вкладку - миграции, бэкапов и прочих задач которые мы в будущем добавим."
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Scheduled Backups (Priority: P1)
+
+As an Administrator, I want to configure automatic backup schedules for my Superset environments so that my data is preserved regularly without manual intervention.
+
+**Why this priority**: Automation is the core request. It ensures data safety and reduces manual toil.
+
+**Independent Test**: Configure a schedule (e.g., every minute for testing), wait, and verify a backup task is created and executed automatically.
+
+**Acceptance Scenarios**:
+
+1. **Given** an environment configuration, **When** I enable scheduled backups with a specific interval (e.g., daily), **Then** the system automatically triggers a backup task at the specified time.
+2. **Given** a scheduled backup runs, **When** it completes, **Then** a new backup archive is present in the storage and a success log is recorded.
+
+---
+
+### User Story 2 - Unified Task Management UI (Priority: P1)
+
+As an Administrator, I want a dedicated "Tasks" tab where I can see and manage all background operations (backups, migrations) in one place.
+
+**Why this priority**: Centralizes visibility and control, improving usability as the number of background tasks grows.
+
+**Independent Test**: Navigate to the new "Tasks" tab and verify it lists both manual and scheduled tasks with their current status.
+
+**Acceptance Scenarios**:
+
+1. **Given** the application is open, **When** I click the "Tasks" tab, **Then** I see a list of recent tasks including their type (Backup, Migration), status, and timestamp.
+2. **Given** a running task, **When** I view the Tasks tab, **Then** I see the task status update in real-time (or near real-time).
+
+---
+
+### User Story 3 - Manual Backup Trigger (Priority: P2)
+
+As an Administrator, I want to manually trigger a backup from the Tasks UI immediately, for example, before a major change.
+
+**Why this priority**: Ad-hoc backups are necessary for operational safety before maintenance.
+
+**Independent Test**: Click "Run Backup" in the UI and verify a new task starts immediately.
+
+**Acceptance Scenarios**:
+
+1. **Given** the Tasks tab is open, **When** I select an environment and click "Run Backup", **Then** a new backup task appears in the list with "Running" status.
+
+---
+
+### User Story 4 - Task History & Logs (Priority: P2)
+
+As an Administrator, I want to view the detailed logs of any executed task to troubleshoot failures or verify success.
+
+**Why this priority**: Essential for debugging and auditability.
+
+**Independent Test**: Click on a completed task and verify the log output is displayed.
+
+**Acceptance Scenarios**:
+
+1. **Given** a list of tasks, **When** I click on a "Failed" task, **Then** I can see the error logs explaining why it failed.
+2. **Given** a "Success" task, **When** I view logs, **Then** I see the execution steps confirmation.
+
+### Edge Cases
+
+- **Concurrent Backups**: What happens if a scheduled backup triggers while a manual backup is already running for the same environment? (System should likely queue or skip).
+- **Storage Full**: How does the system handle backup failures due to insufficient disk space? (Should fail gracefully and log error).
+- **Superset Offline**: What happens if the Superset environment is unreachable when a backup is triggered? (Task fails with connection error).
+
+### Assumptions
+
+- The backend server is running continuously to process scheduled tasks.
+- Users have configured valid credentials for Superset environments.
+- There is sufficient storage space for backup archives.
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: The system MUST allow users to configure a backup schedule using **Cron expressions** for each defined Superset environment via the **Settings** page.
+- **FR-002**: The system MUST persist schedule configurations nested within the Environment configuration in `config.json`.
+- **FR-003**: The system MUST include a `SchedulerService` running in a background thread that triggers backup tasks via the `TaskManager`.
+- **FR-004**: The system MUST provide a dedicated "Tasks" page in the frontend.
+- **FR-005**: The "Tasks" page MUST display a unified list of all `TaskManager` jobs, including Migrations and Backups.
+- **FR-006**: The "Tasks" page MUST allow users to filter tasks by status (Running, Success, Failed) and type.
+- **FR-007**: The system MUST allow users to manually trigger a backup for a specific environment from the "Tasks" page.
+- **FR-008**: All backup operations (scheduled or manual) MUST be executed as `TaskManager` tasks and generate standard logs.
+- **FR-009**: The system MUST retain a history of task executions in a dedicated SQLite database (`tasks.db`) for long-term review.
+- **FR-010**: The system MUST automatically clean up task history older than 30 days to prevent unbounded database growth.
+
+### Key Entities
+
+- **Task**: Represents a unit of work (Backup, Migration) managed by TaskManager. Attributes: ID, Type, Status, StartedAt, FinishedAt, Logs.
+- **Schedule**: Configuration for when to run a task. Attributes: EnvironmentID, Frequency, NextRunTime, Enabled.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: Users can configure a backup schedule that persists and triggers automatically within 1 minute of the target time.
+- **SC-002**: The "Tasks" UI displays the status of running tasks with a latency of no more than 5 seconds.
+- **SC-003**: 100% of triggered backups (manual or scheduled) are recorded in the TaskManager history.
+- **SC-004**: Users can access logs for any task executed in the last 7 days (or configured retention period).
+
+## Clarifications
+
+### Session 2025-12-30
+- Q: Where should the backup schedule configuration UI be located? → A: In the **Settings** tab, inside each Environment's edit form.
+- Q: How should schedule configurations be persisted? → A: Add a `Schedule` model in `config_models.py` and nest it under `Environment`.
+- Q: What format should be used for defining schedule frequency? → A: Cron-style strings (e.g., "0 0 * * *").
+- Q: How should the scheduling mechanism be implemented? → A: Create a dedicated `SchedulerService` in `backend/src/core/scheduler.py` that runs in a background thread.
+- Q: Where should task history be stored for long-term retention? → A: Add a `tasks.db` SQLite database using SQLAlchemy.
