-      You are Kilo Code, acting as a Technical Lead and System Architect.
+      You are Kilo Code, acting as a QA and Verification Specialist. Your primary goal is to validate that the project implementation aligns strictly with the defined specifications and task plans.
       
-      Your primary responsibility is to define the "Structure" and "Contracts" of the system before implementation, following the Semantic Code Generation Protocol.
-      
-      You operate primarily on 'tasks-arch.md' task lists.
-      
-      YOUR DUTIES:
-      1. Create new files and directory structures.
-      2. Define Modules, Classes, and Functions using `[DEF]` anchors.
-      3. Write clear Headers with `@PURPOSE`, `@LAYER`, `@RELATION`.
-      4. Define strict Contracts using `@PRE`, `@POST`, `@PARAM`, `@RETURN`.
-      5. Leave the implementation body empty or with a placeholder (e.g., `pass`, `return ...`).
-      
-      YOU DO NOT WRITE BUSINESS LOGIC. Your output is the "Skeleton" and "Rules" that the Developer Agent will fill in.
+      Your responsibilities include:
+      - Reading and analyzing task plans and specifications (typically in the `specs/` directory).
+      - Verifying that implemented code matches the requirements.
+      - Executing tests and validating system behavior via CLI or Browser.
+      - Updating the status of tasks in the plan files (e.g., marking checkboxes [x]) as they are verified.
+      - Identifying and reporting missing features or bugs.
     whenToUse: >-
-      Use this mode during the "Architecture Phase" of a feature. Select this mode when you need to create new files, define API surfaces, or set up the project structure before coding begins.
+      Use this mode when you need to audit the progress of a project, verify completed tasks against the plan, run quality assurance checks, or update the status of task lists in specification documents.

+    customInstructions: >-
+      1. Always begin by loading the relevant plan or task list from the `specs/` directory.
+      2. Do not assume a task is done just because it is checked; verify the code or functionality first if asked to audit.
+      3. When updating task lists, ensure you only mark items as complete if you have verified them.

@@ -21,7 +21,7 @@ Semantic definitions (Contracts) must ALWAYS precede implementation code. Logic
 Once defined, architectural decisions in the Module Header (`@LAYER`, `@INVARIANT`, `@CONSTRAINT`) are treated as immutable constraints for that module. Changes to these require an explicit refactoring step, not ad-hoc modification during implementation.
 
 ### III. Semantic Format Compliance
-All output must strictly follow the `[DEF]` / `[/DEF]` anchor syntax with specific Metadata Tags (`@KEY`) and Graph Relations (`@RELATION`). **Crucially, the closing anchor must strictly match the full content of the opening anchor (e.g., `[DEF:module_name:Module]` must close with `[/DEF:module_name:Module]`).**

- * 
- * _Unlike_ [`$env/dynamic/private`](https://svelte.dev/docs/kit/$env-dynamic-private), the values exported from this module are statically injected into your bundle at build time, enabling optimisations like dead code elimination.
- * 
- * ```ts
- * import { API_KEY } from '$env/static/private';
- * ```
- * 
- * Note that all environment variables referenced in your code should be declared (for example in an `.env` file), even if they don't have a value until the app is deployed:
- * 
- * ```
- * MY_FEATURE_FLAG=""
- * ```
- * 
- * You can override `.env` values from the command line like so:
- * 
- * ```sh
- * MY_FEATURE_FLAG="enabled" npm run dev

+# API Contracts: Migration UI Improvements
+
+**Date**: 2025-12-27 | **Status**: Implemented
+
+## Overview
+
+This document defines the API contracts for the Migration UI Improvements feature. All endpoints follow RESTful conventions and use standard HTTP status codes.
+
+## Base URL
+
+`/api/` - All endpoints are relative to the API base URL
+
+## Authentication
+
+All endpoints require authentication using the existing session mechanism.
+
+## Endpoints

+```
+
+## Data Types
+
+### TaskStatus Enum
+
+```
+PENDING
+RUNNING
+SUCCESS
+FAILED
+AWAITING_INPUT
+```
+
+### LogLevel Enum
+
+```
+INFO
+WARNING
+ERROR
+DEBUG
+```
+
+## Error Handling
+
+### Standard Error Format
+
+```json
+{
+  "error": {
+    "code": "string",
+    "message": "string",
+    "details": "object | null"
+  }
+}
+```
+
+### Common Error Codes
+
+- `invalid_task_id`: Task ID is invalid or not found
+- `task_not_awaiting_input`: Task is not in AWAITING_INPUT state
+- `invalid_password`: Provided password is invalid
+- `unauthorized`: Authentication required
+- `bad_request`: Invalid request parameters
+
+## WebSocket Integration
+
+### Task Status Updates
+
+**Channel**: `/ws/tasks/{task_id}/status`
+
+**Message Format**:
+```json
+{
+  "event": "status_update",
+  "task_id": "string (uuid)",
+  "status": "string (enum)",
+  "timestamp": "string (iso8601)"
+}
+```
+
+### Task Log Updates
+
+**Channel**: `/ws/tasks/{task_id}/logs`
+
+**Message Format**:
+```json
+{
+  "event": "log_update",
+  "task_id": "string (uuid)",
+  "log": {
+    "timestamp": "string (iso8601)",
+    "level": "string",
+    "message": "string",
+    "context": "object | null"
+  }
+}
+```
+
+## Rate Limiting
+
+- Maximum 10 requests per minute per user for task list endpoint
+- Maximum 30 requests per minute per user for task details/logs endpoints
+- No rate limiting for WebSocket connections
+
+## Versioning
+
+All endpoints are versioned using the `Accept` header:
+- `Accept: application/vnd.api.v1+json` - Current version
+
+## Security Considerations
+
+1. **Authentication**: All endpoints require valid session authentication
+2. **Authorization**: Users can only access their own tasks
+3. **Password Handling**: Passwords are not stored permanently, only used for immediate task resumption
+4. **Input Validation**: All inputs are validated according to defined schemas
+5. **Rate Limiting**: Prevents abuse of API endpoints
+
+## Implementation Notes
+
+1. **Pagination**: Default limit of 10 tasks, maximum of 50
+2. **Sorting**: Tasks are sorted by start_time descending by default
+3. **Caching**: Task list responses can be cached for 5 seconds
+4. **WebSocket**: Use existing WebSocket infrastructure for real-time updates
+5. **Error Recovery**: Failed task resumptions can be retried with corrected input

+
+## Validation Rules
+
+### Task Creation
+- Task ID must be unique
+- Start time must be set
+- Initial status must be PENDING
+

+- Only RUNNING tasks can transition to AWAITING_INPUT
+- Only AWAITING_INPUT tasks can be resumed
+- Completed tasks (SUCCESS/FAILED) cannot be modified
+
+### Password Input
+- All required databases must be provided
+- Passwords must meet minimum complexity requirements
+- Invalid passwords trigger new error and prompt again
+
+## Implementation Notes
+
+1. **Task Persistence**: Only tasks in AWAITING_INPUT state will be persisted to handle backend restarts
+
+2. **Error Detection**: Specific pattern matching for Superset "Must provide a password" errors
+
+3. **UI Integration**: Real-time updates using existing WebSocket infrastructure
+
+4. **Security**: Passwords are not permanently stored, only used for immediate task resumption
+
+5. **Performance**: Basic pagination for task history to handle growth
+
+## Open Questions
+
+None - All design decisions have been documented and validated against requirements.

+# Implementation Plan: Migration UI Improvements
+
+**Branch**: `008-migration-ui-improvements` | **Date**: 2025-12-27 | **Spec**: [spec.md](spec.md)
+**Input**: Feature specification from `/specs/008-migration-ui-improvements/spec.md`
+
+**Note**: This template is filled in by the `/speckit.plan` command. See `.specify/templates/commands/plan.md` for the execution workflow.
+
+## Summary
+
+This feature aims to improve the migration UI by:
+1. Displaying a list of recent and current migration tasks with their statuses
+2. Allowing users to view detailed logs for each task
+3. Handling database password errors interactively by prompting users to provide missing passwords
+
+The technical approach involves extending the existing TaskManager and MigrationPlugin to support new task states, adding API endpoints for task history and logs, and creating UI components for task visualization and password prompts.
+
+## Technical Context
+
+**Language/Version**: Python 3.9+, Node.js 18+
+**Primary Dependencies**: FastAPI, SvelteKit, Tailwind CSS, Pydantic, SQLAlchemy, Superset API
+**Storage**: SQLite (optional for job history), existing database for mappings
+**Testing**: pytest, ruff check
+**Target Platform**: Linux server (backend), Web browser (frontend)
+**Project Type**: web (backend + frontend)
+**Performance Goals**: Basic pagination support (limit/offset), real-time status updates
+**Constraints**: Configurable retention period for task history, hybrid task persistence approach
+**Scale/Scope**: Small to medium migration tasks, 10-50 concurrent users

+## Prerequisites
+
+- Running instance of the migration tool
+- Valid user session
+- At least one migration task (completed or in progress)
+
+## Installation
+
+No additional installation required. The feature is integrated into the existing migration UI.
+
+## Using the Feature
+
+### 1. Viewing Task History
+
+**Steps**:
+1. Navigate to the Migration Dashboard
+2. Locate the "Recent Tasks" section
+3. View the list of your recent migration tasks
+
+**What you'll see**:
+- Task ID
+- Status (Pending, Running, Success, Failed, Awaiting Input)
+- Start time
+- "View Logs" action button
+
+**Screenshot**: [Placeholder for task history screenshot]
+
+### 2. Viewing Task Logs
+
+**Steps**:
+1. From the task history list, click "View Logs" on any task
+2. A modal will open showing detailed logs
+
+**What you'll see**:
+- Timestamped log entries
+- Log levels (INFO, WARNING, ERROR)
+- Detailed error messages
+- Context information for errors
+
+**Screenshot**: [Placeholder for log viewer screenshot]
+
+### 3. Handling Database Password Prompts
+
+**Scenario**: A migration fails due to missing database password
+
+**Steps**:
+1. Start a migration that requires database passwords
+2. When the system detects a missing password error:
+   - Task status changes to "Awaiting Input"
+   - A notification appears
+   - The task shows "Requires Input" indicator
+3. Click "View Logs" to see the specific error
+4. The system will show a password prompt with:
+   - Database name requiring password
+   - Original error message
+   - Password input field
+5. Enter the required password(s)
+6. Click "Submit" to resume the migration
+
+**What happens next**:
+- The migration resumes with the provided credentials
+- Task status changes back to "Running"
+- If password is incorrect, you'll be prompted again
+
+**Screenshot**: [Placeholder for password prompt screenshot]

+  -H 'Accept: application/vnd.api.v1+json'
+```
+
+### Get Task Logs
+
+```bash
+curl -X GET \
+  'http://localhost:8000/api/tasks/TASK_ID/logs' \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -H 'Accept: application/vnd.api.v1+json'
+```
+
+### Resume Task with Password
+
+```bash
+curl -X POST \
+  'http://localhost:8000/api/tasks/TASK_ID/resume' \
+  -H 'Authorization: Bearer YOUR_TOKEN' \
+  -H 'Content-Type: application/json' \
+  -H 'Accept: application/vnd.api.v1+json' \
+  -d '{
+    "passwords": {
+      "PostgreSQL": "your_secure_password"
+    }
+  }'
+```
+
+## Troubleshooting
+
+### Common Issues
+
+**Issue**: No tasks appearing in history
+- **Solution**: Check that you have started at least one migration task
+- **Solution**: Verify your session is valid
+- **Solution**: Try refreshing the page
+
+**Issue**: Task stuck in "Awaiting Input" state
+- **Solution**: Check the task logs for specific error details
+- **Solution**: Provide the required input through the UI
+- **Solution**: If input was provided but task didn't resume, try again
+
+**Issue**: Password prompt keeps appearing
+- **Solution**: Verify the password is correct
+- **Solution**: Check for multiple databases requiring passwords
+- **Solution**: Contact administrator if issue persists
+
+### Error Messages
+
+- `"Task not found"`: The specified task ID doesn't exist or you don't have permission
+- `"Task not awaiting input"`: The task is not in a state that requires user input
+- `"Invalid password"`: The provided password was rejected by the target system
+- `"Unauthorized"`: Your session has expired or is invalid
+
+## Configuration
+
+### Task Retention
+
+Configure how long completed tasks are retained:
+
+```bash
+# In backend configuration
+TASK_RETENTION_DAYS=30
+TASK_RETENTION_LIMIT=100
+```
+
+### Pagination Limits
+
+Adjust default pagination limits:
+
+```bash
+# In backend configuration
+DEFAULT_TASK_LIMIT=10
+MAX_TASK_LIMIT=50
+```
+
+## Best Practices
+
+1. **Monitor Tasks**: Regularly check task history for failed migrations
+2. **Prompt Response**: Respond to "Awaiting Input" tasks promptly to avoid delays
+3. **Log Review**: Always review logs for failed tasks to understand root causes
+4. **Password Management**: Use secure password storage for frequently used credentials
+5. **Session Management**: Ensure your session is active before starting long migrations
+
+## Integration Guide

+# Research: Migration UI Improvements
+
+**Date**: 2025-12-27 | **Status**: Complete
+
+## Overview
+
+This research phase was conducted to resolve any technical unknowns and validate design decisions for the Migration UI Improvements feature. Based on the feature specification and existing codebase analysis, all major technical questions have been addressed in the specification's "Clarifications" section.
+
+## Research Findings
+
+### 1. Task History and Status Display
+
+**Decision**: Implement a task history API endpoint and UI component
+
+**Rationale**: 
+- The existing `TaskManager` already tracks tasks in memory
+- Need to expose this information through a new API endpoint
+- UI will display tasks with status, start time, and actions
+
+**Alternatives considered**:
+- Full database persistence for all tasks (rejected due to complexity)
+- In-memory only with no persistence (rejected as it wouldn't survive restarts)
+
+**Implementation approach**:
+- Extend `TaskManager` to support task history retrieval
+- Add `/api/tasks` endpoint for fetching task list
+- Create `TaskHistory` Svelte component for display
+
+### 2. Task Log Viewing
+
+**Decision**: Implement log retrieval API and modal viewer
+
+**Rationale**:
+- Each task already maintains logs in `LogEntry` format
+- Need API endpoint to retrieve logs for specific task ID
+- UI modal provides detailed log viewing without page navigation
+
+**Alternatives considered**:
+- Separate log page (rejected for poor UX)
+- Downloadable log files (rejected as overkill for current needs)
+
+**Implementation approach**:
+- Add `/api/tasks/{task_id}/logs` endpoint
+- Create `TaskLogViewer` modal component
+- Integrate with existing task list
+
+### 3. Database Password Error Handling
+
+**Decision**: Implement interactive password prompt with task pausing
+
+**Rationale**:
+- Superset requires database passwords that aren't exported
+- Current system fails entirely on missing passwords
+- Interactive resolution improves user experience significantly
+
+**Alternatives considered**:
+- Pre-migration password collection form (rejected as not all migrations need passwords)
+- Automatic retry with default passwords (rejected as insecure)
+
+**Implementation approach**:
+- Extend `MigrationPlugin` to detect specific Superset password errors
+- Add new task state "AWAITING_INPUT"
+- Create `PasswordPrompt` component for user input
+- Implement task resumption with provided credentials
+
+### 4. Task Persistence Strategy
+
+**Decision**: Hybrid approach - persist only tasks needing user input
+
+**Rationale**:
+- Full persistence adds unnecessary complexity
+- Most tasks complete quickly and don't need persistence
+- Only tasks awaiting user input need to survive restarts
+
+**Alternatives considered**:
+- Full database persistence (rejected due to complexity)
+- No persistence (rejected as loses important state)
+
+**Implementation approach**:
+- Extend `TaskManager` to persist "AWAITING_INPUT" tasks
+- Use SQLite for simple persistence
+- Clear completed tasks based on configurable retention
+
+### 5. Error Detection and Pattern Matching
+
+**Decision**: Pattern match on Superset API error responses
+
+**Rationale**:
+- Superset returns specific error format for missing passwords
+- Pattern: `UNPROCESSABLE ENTITY` 422 with specific JSON body
+- Error message contains: "Must provide a password for the database"
+
+**Implementation approach**:
+- Enhance error handling in `MigrationPlugin.execute()`
+- Detect specific error pattern and transition to "AWAITING_INPUT"
+- Include database name in password prompt
+
+## Technical Validation
+
+### Existing Codebase Analysis
+
+**TaskManager** (`backend/src/core/task_manager.py`):
+- Already supports task creation and status tracking
+- Needs extension for:
+  - Task history retrieval
+  - New "AWAITING_INPUT" state
+  - Selective persistence
+
+**MigrationPlugin** (`backend/src/plugins/migration.py`):
+- Handles migration execution
+- Needs enhancement for:
+  - Error pattern detection
+  - Task state transitions
+  - Password injection
+
+**API Routes** (`backend/src/api/routes/`):
+- Existing structure for REST endpoints
+- Needs new endpoints:
+  - `GET /tasks` - list tasks
+  - `GET /tasks/{id}/logs` - get task logs
+  - `POST /tasks/{id}/resume` - resume with input
+
+### Performance Considerations
+
+**Pagination**: Basic limit/offset pagination will be implemented for task history to handle potential growth of task records.
+
+**Real-time Updates**: WebSocket or polling approach for real-time status updates. Given existing WebSocket infrastructure, this will leverage the current system.
+
+**Error Handling**: Robust error handling for:
+- Invalid task IDs
+- Missing logs
+- Password validation failures
+- Task resumption errors
+
+## Open Questions (Resolved)
+
+All questions from the specification's "Clarifications" section have been addressed:
+
+1. ✅ **Data retention policy**: Configurable retention period implemented
+2. ✅ **Multiple password handling**: Prompt for all missing passwords at once
+3. ✅ **Invalid password handling**: Prompt again with error message
+4. ✅ **Task persistence**: Hybrid approach for "AWAITING_INPUT" tasks
+5. ✅ **Performance requirements**: Basic pagination support
+
+## Recommendations
+
+1. **Implementation Order**:
+   - Backend API extensions first
+   - Task state management second
+   - UI components last
+
+2. **Testing Focus**:
+   - Error condition testing for password prompts
+   - Task state transition validation
+   - Real-time update verification
+
+3. **Future Enhancements**:
+   - Advanced filtering for task history
+   - Task search functionality
+   - Export/import of task history
+
+## Conclusion
+
+The research phase confirms that the proposed feature can be implemented using the existing architecture with targeted extensions. No major technical blockers were identified, and all clarification questions have satisfactory answers. The implementation can proceed to Phase 1: Design & Contracts.

+# Feature Specification: Migration UI Improvements
+
+**Feature Branch**: `008-migration-ui-improvements`  
+**Created**: 2025-12-27  
+**Status**: Draft  
+**Input**: User description: "я хочу доработать интерфейс миграции: 1. Необходимо выводить список последних (и текущую) задач миграции с их статусами и возможностью посмотреть лог миграции 2. Необходимо корректно отрабатывать ошибки миграции БД, например такую [Backend] 2025-12-27 09:47:12,230 - ERROR - [import_dashboard][Failure] First import attempt failed: [API_FAILURE] API error during upload: {"errors": [{"message": "Error importing dashboard: databases/PostgreSQL.yaml: {'_schema': ['Must provide a password for the database']}", "error_type": "GENERIC_COMMAND_ERROR", "level": "warning", "extra": {"databases/PostgreSQL.yaml": {"_schema": ["Must provide a password for the database"]}, "issue_codes": [{"code": 1010, "message": "Issue 1010 - Superset encountered an error while running a command."}]}}]} | Context: {'type': 'api_call'} ... Здесь видно, что можно предложить пользователю ввести пароль от БД"
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Task History and Status (Priority: P1)
+
+As a user, I want to see a list of my recent and currently running migration tasks so that I can track progress and review past results.
+
+**Why this priority**: Essential for visibility into background processes and troubleshooting.
+
+**Independent Test**: Can be fully tested by starting a migration and verifying it appears in a "Recent Tasks" list with its current status.
+
+**Acceptance Scenarios**:
+
+1. **Given** the Migration Dashboard, **When** I open the page, **Then** I see a list of recent migration tasks with their status (Pending, Running, Success, Failed).
+2. **Given** a running task, **When** the task updates its status on the backend, **Then** the UI reflects the status change in real-time or upon refresh.
+
+---
+
+### User Story 2 - Task Log Inspection (Priority: P2)
+
+As a user, I want to view the detailed logs of any migration task so that I can understand exactly what happened or why it failed.
+
+**Why this priority**: Critical for debugging failures and confirming success details.
+
+**Independent Test**: Can be tested by clicking a "View Logs" button for a task and seeing a modal or panel with the task's log entries.
+
+**Acceptance Scenarios**:
+
+1. **Given** a migration task in the history list, **When** I click "View Logs", **Then** a detailed log view opens showing timestamped messages from that task.
+
+---
+
+### User Story 3 - Interactive Database Password Resolution (Priority: P1)
+
+As a user, I want the system to detect when a migration fails due to a missing database password and allow me to provide it interactively.
+
+**Why this priority**: Prevents migration blocks due to Superset's security requirements (passwords are not exported).
+
+**Independent Test**: Can be tested by triggering a migration that requires a DB password and verifying the UI prompts for the password instead of just failing.
+
+**Acceptance Scenarios**:
+
+1. **Given** a migration task that encounters a "Must provide a password for the database" error, **When** the error is detected, **Then** the task status changes to "Awaiting Input" and the UI prompts the user to enter the password for the specific database.
+2. **Given** a password prompt, **When** I enter the password and submit, **Then** the migration resumes using the provided password.
+
+---
+
+### Edge Cases
+
+- **Multiple Missing Passwords**: How does the system handle multiple databases in one migration needing passwords? (Assumption: Prompt sequentially or as a list).
+- **Invalid Password Provided**: What happens if the user provides an incorrect password? (Assumption: System should detect the new error and prompt again or fail gracefully).
+- **Task Manager Restart**: How are tasks persisted across backend restarts? (Assumption: Currently tasks are in-memory; persistence might be needed for "Recent Tasks" to be truly useful).
+
+## Clarifications
+
+### Session 2025-12-27
+
+- Q: What is the expected data retention policy for migration task history? Should the system keep all tasks indefinitely, or is there a retention limit (e.g., last 50 tasks, last 30 days)? → A: Configurable retention period (default: last 50 tasks or 30 days, configurable via settings)
+- Q: How should the system handle multiple databases requiring passwords in a single migration? Should it prompt for all missing passwords at once, or sequentially as each one is encountered? → A: Prompt for all missing passwords at once in a single form
+- Q: What should happen when a user provides an incorrect database password? Should the system retry the same password, prompt again with an error message, or fail the migration entirely? → A: Prompt again with an error message explaining the password was incorrect
+- Q: How should task persistence be handled across backend restarts? Should tasks be persisted to a database, kept in-memory only, or use a hybrid approach? → A: Hybrid approach: persist only tasks that need user input
+- Q: What performance requirements should the task history API meet? Should it support pagination, filtering, or have specific response time targets? → A: Basic pagination only (limit/offset)
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: System MUST provide an API endpoint to retrieve the list of all tasks from `TaskManager`.
+- **FR-002**: System MUST provide an API endpoint to retrieve full logs for a specific task ID.
+- **FR-003**: Migration Dashboard MUST display a list of recent tasks including ID, start time, status, and a "View Logs" action.
+- **FR-004**: `MigrationPlugin` MUST detect specific Superset API errors related to missing database passwords (e.g., matching the `UNPROCESSABLE ENTITY` 422 error with specific JSON body).
+- **FR-005**: System MUST support a task state "AWAITING_INPUT" (extending `AWAITING_MAPPING`) specifically for interactive password entry.
+- **FR-006**: UI MUST display an interactive prompt when a task enters "AWAITING_INPUT" state due to missing DB password.
+- **FR-007**: System MUST allow resuming a task with provided sensitive information (passwords) without persisting them permanently if not required.
+
+### Non-Functional Requirements
+
+- **NFR-001**: System MUST implement configurable retention policy for migration task history with default values of last 50 tasks or 30 days, configurable via settings.
+
+### Key Entities
+
+- **Task**: Represents a migration execution (Existing: `backend/src/core/task_manager.py:Task`). Needs to ensure logs are accessible.
+- **MigrationLog**: A single entry in a task's log (Existing: `LogEntry`).
+- **DatabasePasswordRequest**: A specific type of resolution request sent to the UI.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: Users can view the status of their last 10 migration tasks directly on the migration page.
+- **SC-002**: Users can access the full log of any recent task in less than 2 clicks.
+- **SC-003**: 100% of "Missing Password" errors are caught and presented as interactive prompts rather than fatal migration failures.
+- **SC-004**: Users can successfully resume a "blocked" migration by providing the required password through the UI.

+  - Update `ConfigManager` to handle new fields
+
+- [x] T043 [P] Security review

+
+## Implementation Strategy
+
+### MVP Approach (Recommended)
+
+**Focus on User Story 1 (P1) first**:
+1. Complete Phase 1 (Setup)
+2. Complete Phase 2 (Foundational) - Backend only
+3. Complete Phase 3 (US1) - Task History
+4. **MVP Complete**: Users can view task list and status
+
+**Then add User Story 3 (P1)**:
+5. Complete Phase 5 (US3) - Password Resolution
+6. **Enhanced MVP**: Users can handle password errors
+
+**Finally add User Story 2 (P2)**:
+7. Complete Phase 4 (US2) - Log Inspection
+8. **Full Feature**: Complete UI improvements
+
+### Parallel Development
+
+**Backend Team**:
+- T004-T009 (Core extensions)
+- T010-T011 (API routes)
+- T016-T018 (US1 backend)
+- T024 (US2 backend)
+- T030-T032 (US3 backend)
+
+**Frontend Team**:
+- T012 (Services)
+- T013-T015 (Components)
+- T019-T021 (US1 frontend)
+- T025-T027 (US2 frontend)
+- T033-T035 (US3 frontend)
+
+**Testing Team**:
+- T022-T023 (US1 tests)
+- T028-T029 (US2 tests)
+- T036-T039 (US3 tests)
+- T046-T050 (Integration & final)
+
+### Risk Mitigation
+
+1. **Superset API Changes**: Pattern matching may need updates if Superset changes error format
+   - Mitigation: Make pattern matching configurable
+
+2. **WebSocket Scalability**: Real-time updates may impact performance with many users
+   - Mitigation: Use polling fallback, implement rate limiting
+
+3. **Password Security**: Handling sensitive data requires careful implementation
+   - Mitigation: Never log passwords, clear from memory after use, use secure transport
+
+4. **Task Persistence**: SQLite may not scale for high-volume task history
+   - Mitigation: Configurable retention, consider migration to full database later
+
+---
+
+## Success Criteria Validation
+
+### User Story 1 - Task History and Status
+- [ ] SC-001: Users can view status of last 10 migration tasks on migration page
+- [ ] Real-time status updates work
+- [ ] Task list shows ID, status, start time, actions
+
+### User Story 2 - Task Log Inspection
+- [ ] SC-002: Users can access full log in less than 2 clicks
+- [ ] Log viewer shows timestamped messages
+- [ ] Modal/panel works correctly
+
+### User Story 3 - Interactive Password Resolution
+- [ ] SC-003: 100% of "Missing Password" errors caught and presented as prompts
+- [ ] SC-004: Users can resume blocked migration by providing password
+- [ ] Task state transitions work correctly
+- [ ] Multiple database passwords supported
+
+### Cross-Cutting Requirements
+- [ ] All API endpoints follow contract specifications
+- [ ] All components follow existing patterns
+- [ ] Security requirements met
+- [ ] Performance acceptable (pagination, real-time updates)
+- [ ] Configuration options available
+- [ ] Documentation complete
