+    *   Ref: `.ai/standards/plugin_design.md` -> `[DEF:Std:Plugin]`
+*   **API Design:** Rules for FastAPI endpoints and Pydantic models.
+    *   Ref: `.ai/standards/api_design.md` -> `[DEF:Std:API_FastAPI]`
+*   **UI Design:** SvelteKit and Tailwind CSS component standards.

+*   **Config:** Use `Depends(get_config_manager)` for settings. Hardcoding is FORBIDDEN.
+*   **Tasks:** Long-running operations must be executed via `TaskManager`. API routes should return Task ID and be non-blocking.
+
+## 4. ERROR HANDLING
+*   Raise `HTTPException` from the router layer.

+
+## 1. ORCHESTRATOR VS INSTANCE

+*   **Isolation:** Do not integrate directly into Superset as a plugin to maintain multi-environment management capability.

+# @VERSION: 2.3.0
+# @LAST_UPDATE: 2026-02-19
+# @INVARIANT: Any deviation from this Constitution constitutes a build failure.
+
+## 1. CORE PRINCIPLES
+
+### I. Semantic Protocol Compliance
+*   **Ref:** `[DEF:Std:Semantics]` (formerly `semantic_protocol.md`)
+*   **Law:** All code must adhere to the Axioms (Meaning First, Contract First, etc.).
+*   **Compliance:** Strict matching of Anchors (`[DEF]`), Tags (`@KEY`), and structures is mandatory.
+
+### II. Modular Plugin Architecture
+*   **Pattern:** Everything is a Plugin inheriting from `PluginBase`.
+*   **Centralized Config:** Use `ConfigManager` via `get_config_manager()`. Hardcoding is FORBIDDEN.
+
+### III. Unified Frontend Experience
+*   **Styling:** Tailwind CSS First. Minimize scoped `<style>`.
+*   **i18n:** All user-facing text must be in `src/lib/i18n`.
+*   **API:** Use `requestApi` / `fetchApi` wrappers. Native `fetch` is FORBIDDEN.
+
+### IV. Security & RBAC
+*   **Permissions:** Every Plugin must define unique permission strings (e.g., `plugin:name:execute`).
+*   **Auth:** Mandatory registration in `auth.db`.
+
+### V. Independent Testability
+*   **Requirement:** Every feature must define "Independent Tests" for isolated verification.
+
+### VI. Asynchronous Execution
+*   **TaskManager:** Long-running operations must be async tasks.
+*   **Non-Blocking:** API endpoints return Task ID immediately.
+*   **Observability:** Real-time updates via WebSocket.

+# [DEF:Std:Plugin:Standard]
+# @TIER: CRITICAL
+# @PURPOSE: Standards for building and integrating Plugins.
+# @LAYER: Domain (Plugin)
+# @INVARIANT: All plugins MUST inherit from `PluginBase`.
+# @INVARIANT: All plugins MUST be located in `backend/src/plugins/`.
+
+## 1. PLUGIN CONTRACT
+Every plugin must implement the following properties and methods:
+*   `id`: Unique string (e.g., `"my-plugin"`).
+*   `name`: Human-readable name.
+*   `description`: Brief purpose.
+*   `version`: Semantic version.
+*   `get_schema()`: Returns JSON schema for input validation.
+*   `execute(params: Dict[str, Any], context: TaskContext)`: Core async logic.
+
+## 2. STRUCTURED LOGGING (TASKCONTEXT)
+Plugins MUST use `TaskContext` for logging to ensure proper source attribution:
+*   **Source Attribution:** Use `context.logger.with_source("src_name")` for specific operations (e.g., `"superset_api"`, `"git"`, `"llm"`).
+*   **Levels:**
+    *   `DEBUG`: Detailed diagnostics (API responses).
+    *   `INFO`: Operational milestones (start/end).
+    *   `WARNING`: Recoverable issues.
+    *   `ERROR`: Failures stopping execution.
+*   **Progress:** Use `context.logger.progress("msg", percent=XX)` for long-running tasks.
+
+## 3. BEST PRACTICES
+1. **Asynchronous Execution:** Always use `async/await` for I/O operations.
+2. **Schema Validation:** Ensure the `get_schema()` precisely matches the `execute()` input expectations.
+3. **Isolation:** Plugins should be self-contained and not depend on other plugins directly. Use core services (`ConfigManager`, `TaskManager`) via dependency injection or the provided `context`.

+1. HEADER (Всегда первый):
+   [DEF:filename:Module]
+   @TIER: [CRITICAL|STANDARD|TRIVIAL] (Дефолт: STANDARD)
+   @SEMANTICS: [keywords]
+   @PURPOSE: [Главная цель]
+   @LAYER: [Domain/UI/Infra]
+   @RELATION: [Зависимости]
+   @INVARIANT: [Незыблемое правило]
+   
+2. BODY: Импорты -> Реализация.
+3. FOOTER: [/DEF:filename]
+
+#### IV. КОНТРАКТ (DBC & UX)
+Расположение: Внутри [DEF], ПЕРЕД кодом.
+Стиль Python: Комментарии `# @TAG`.
+Стиль Svelte: JSDoc `/** @tag */` внутри `<script>`.
+
+**Базовые Теги:**
+  @PURPOSE: Суть (High Entropy).
+  @PRE: Входные условия.
+  @POST: Гарантии выхода.
+  @SIDE_EFFECT: Мутации, IO.
+  
+**UX Теги (Svelte/Frontend):**
+  **@UX_STATE:** `[StateName] -> Визуальное поведение` (Idle, Loading, Error).
+  **@UX_FEEDBACK:** Реакция системы (Toast, Shake, Red Border).
+  **@UX_RECOVERY:** Механизм исправления ошибки пользователем (Retry, Clear Input).
+  
+**UX Testing Tags (для Tester Agent):**
+  **@UX_TEST:** Спецификация теста для UX состояния.
+  Формат: `@UX_TEST: [state] -> {action, expected}`
+  Пример: `@UX_TEST: Idle -> {click: toggle, expected: isExpanded=true}`
+  
+Правило: Не используй `assert` в коде, используй `if/raise` или `guards`.
+
+#### V. АДАПТАЦИЯ (TIERS)
+Определяется тегом `@TIER` в Header.
+
+1. **CRITICAL** (Core/Security/**Complex UI**):
+   - Требование: Полный контракт (включая **все @UX теги**), Граф, Инварианты, Строгие Логи.
+   - **@TEST_DATA**: Обязательные эталонные данные для тестирования. Формат:
+     ```
+     @TEST_DATA: fixture_name -> {JSON_PATH} | {INLINE_DATA}
+     ```
+     Примеры:
+     - `@TEST_DATA: valid_user -> {./fixtures/users.json#valid}`
+     - `@TEST_DATA: empty_state -> {"dashboards": [], "total": 0}`
+   - Tester Agent **ОБЯЗАН** использовать @TEST_DATA при написании тестов для CRITICAL модулей.
+2. **STANDARD** (BizLogic/**Forms**):
+   - Требование: Базовый контракт (@PURPOSE, @UX_STATE), Логи, @RELATION.
+   - @TEST_DATA: Рекомендуется для Complex Forms.
+3. **TRIVIAL** (DTO/**Atoms**):
+   - Требование: Только Якоря [DEF] и @PURPOSE.
+
+#### VI. ЛОГИРОВАНИЕ (BELIEF STATE & TASK LOGS)
+Цель: Трассировка для самокоррекции и пользовательский мониторинг.
+Python: 
+  - Системные логи: Context Manager `with belief_scope("ID"):`.
+  - Логи задач: `context.logger.info("msg", source="component")`.
+Svelte: `console.log("[ID][STATE] Msg")`.
+Состояния: Entry -> Action -> Coherence:OK / Failed -> Exit.
+Инвариант: Каждый лог задачи должен иметь атрибут `source` для фильтрации.
+
+#### VII. АЛГОРИТМ ГЕНЕРАЦИИ
+1. АНАЛИЗ. Оцени TIER, слой и UX-требования.
+2. КАРКАС. Создай `[DEF]`, Header и Контракты.
+3. РЕАЛИЗАЦИЯ. Напиши логику, удовлетворяющую Контракту (и UX-состояниям).
+4. ЗАМЫКАНИЕ. Закрой все `[/DEF]`.
+
+ЕСЛИ ошибка или противоречие -> СТОП. Выведи `[COHERENCE_CHECK_FAILED]`.

+# [DEF:Std:UI_Svelte:Standard]
+# @TIER: CRITICAL
+# @PURPOSE: Unification of all Svelte components following GRACE-Poly (UX Edition).
+# @LAYER: UI
+# @INVARIANT: Every component MUST have `<!-- [DEF:] -->` anchors and UX tags.
+# @INVARIANT: Use Tailwind CSS for all styling (no custom CSS without justification).
+
+## 1. UX PHILOSOPHY: RESOURCE-CENTRIC & SVELTE 5
+*   **Version:** Project uses Svelte 5.
+*   **Runes:** Use Svelte 5 Runes for reactivity: `$state()`, `$derived()`, `$effect()`, `$props()`. Traditional `let` (for reactivity) and `export let` (for props) are DEPRECATED in favor of runes.
+*   **Definition:** Navigation and actions revolve around Resources.
+*   **Traceability:** Every action must be linked to a Task ID with visible logs in the Task Drawer.
+
+## 2. COMPONENT ARCHITECTURE: GLOBAL TASK DRAWER
+*   **Role:** A single, persistent slide-out panel (`GlobalTaskDrawer.svelte`) in `+layout.svelte`.
+*   **Triggering:** Opens automatically when a task starts or when a user clicks a status badge.
+*   **Interaction:** Interactive elements (Password prompts, Mapping tables) MUST be rendered INSIDE the Drawer, not as center-screen modals.
+
+## 3. COMPONENT STRUCTURE & CORE RULES
+*   **Styling:** Tailwind CSS utility classes are MANDATORY. Minimize scoped `<style>`.
+*   **Localization:** All user-facing text must use `$t` from `src/lib/i18n`.
+*   **API Calls:** Use `requestApi` / `fetchApi` wrappers. Native `fetch` is FORBIDDEN.
+*   **Anchors:** Every component MUST have `<!-- [DEF:] -->` anchors and UX tags.
+
+## 2. COMPONENT TEMPLATE
+Each Svelte file must follow this structure:
+```html
+<!-- [DEF:ComponentName:Component] -->
+<script>
+  /**
+   * @TIER: [CRITICAL | STANDARD | TRIVIAL]
+   * @PURPOSE: Brief description of the component purpose.
+   * @LAYER: UI
+   * @SEMANTICS: list, of, keywords
+   * @RELATION: DEPENDS_ON -> [OtherComponent|Store]
+   * 
+   * @UX_STATE: [StateName] -> Visual behavior description.
+   * @UX_FEEDBACK: System reaction (e.g., Toast, Shake).
+   * @UX_RECOVERY: Error recovery mechanism.
+   * @UX_TEST: [state] -> {action, expected}
+   */
+  import { ... } from "...";
+  
+  // Exports (Props)
+  export let prop_name = "...";
+  
+  // Logic
+</script>
+
+<!-- HTML Template -->
+<div class="...">
+  ...
+</div>
+
+<style>
+  /* Optional: Local styles using @apply only */
+</style>
+<!-- [/DEF:ComponentName:Component] -->
+```
+
+## 2. STATE MANAGEMENT & STORES
+*   **Subscription:** Use `$` prefix for reactive store access (e.g., `$sidebarStore`).
+*   **Data Flow:** Mark store interactions in `[DEF:]` metadata:
+    *   `# @RELATION: BINDS_TO -> store_id`
+
+## 3. UI/UX BEST PRACTICES
+*   **Transitions:** Use Svelte built-in transitions for UI state changes.
+*   **Feedback:** Always provide visual feedback for async actions (Loading spinners, skeleton loaders).
+*   **Modularity:** Break down components into "Atoms" (Trivial) and "Orchestrators" (Critical).
+
+## 4. ACCESSIBILITY (A11Y)
+*   Ensure proper ARIA roles and keyboard navigation for interactive elements.
+*   Use semantic HTML tags (`<nav>`, `<header>`, `<main>`, `<footer>`).

+description: Fix failing tests and implementation issues based on test reports
+
+---
+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Goal
+
+Analyze test failure reports, identify root causes, and fix implementation issues while preserving semantic protocol compliance.
+
+## Operating Constraints
+
+1. **USE CODER MODE**: Always switch to `coder` mode for code fixes
+2. **SEMANTIC PROTOCOL**: Never remove semantic annotations ([DEF], @TAGS). Only update code logic.
+3. **TEST DATA**: If tests use @TEST_DATA fixtures, preserve them when fixing
+4. **NO DELETION**: Never delete existing tests or semantic annotations
+5. **REPORT FIRST**: Always write a fix report before making changes
+
+## Execution Steps
+
+### 1. Load Test Report
+
+**Required**: Test report file path (e.g., `specs/<feature>/tests/reports/2026-02-19-report.md`)
+
+**Parse the report for**:
+- Failed test cases
+- Error messages
+- Stack traces
+- Expected vs actual behavior
+- Affected modules/files
+
+### 2. Analyze Root Causes
+
+For each failed test:
+
+1. **Read the test file** to understand what it's testing
+2. **Read the implementation file** to find the bug
+3. **Check semantic protocol compliance**:
+   - Does the implementation have correct [DEF] anchors?
+   - Are @TAGS (@PRE, @POST, @UX_STATE, etc.) present?
+   - Does the code match the TIER requirements?
+4. **Identify the fix**:
+   - Logic error in implementation
+   - Missing error handling
+   - Incorrect API usage
+   - State management issue
+
+### 3. Write Fix Report
+
+Create a structured fix report:
+
+```markdown
+# Fix Report: [FEATURE]
+
+**Date**: [YYYY-MM-DD]
+**Report**: [Test Report Path]
+**Fixer**: Coder Agent
+
+## Summary

+### Fix 1: [Description]
+
+**Affected File**: `path/to/file.py`
+**Test Affected**: `[Test Name]`

+**Changes**:
+```diff
+<<<<<<< SEARCH
+[Original Code]
+=======
+[Fixed Code]
+>>>>>>> REPLACE
+```
+
+**Verification**: [How to verify fix works]
+
+**Semantic Integrity**: [Confirmed annotations preserved]
+
+## Next Steps
+
+- [ ] Run tests to verify fix: `cd backend && .venv/bin/python3 -m pytest`
+- [ ] Check for related failing tests
+- [ ] Update test documentation if needed
+```
+
+### 4. Apply Fixes (in Coder Mode)
+
+Switch to `coder` mode and apply fixes:
+
+1. **Read the implementation file** to get exact content
+2. **Apply the fix** using apply_diff
+3. **Preserve all semantic annotations**:
+   - Keep [DEF:...] and [/DEF:...] anchors
+   - Keep all @TAGS (@PURPOSE, @LAYER, @TIER, @RELATION, @PRE, @POST, @UX_STATE, @UX_FEEDBACK, @UX_RECOVERY)
+4. **Only update code logic** to fix the bug
+5. **Run tests** to verify the fix
+
+### 5. Verification
+
+After applying fixes:
+
+1. **Run tests**:
+   ```bash
+   cd backend && .venv/bin/python3 -m pytest -v
+   ```
+   or
+   ```bash
+   cd frontend && npm run test
+   ```
+
+2. **Check test results**:
+   - Failed tests should now pass
+   - No new tests should fail
+   - Coverage should not decrease
+
+3. **Update fix report** with results:
+   - Mark fixes as completed
+   - Add verification steps
+   - Note any remaining issues
+
+## Output
+
+Generate final fix report:
+
+```markdown
+# Fix Report: [FEATURE] - COMPLETED
+
+**Date**: [YYYY-MM-DD]
+**Report**: [Test Report Path]
+**Fixer**: Coder Agent

-   - **Optional**: data-model.md (entities), contracts/ (API endpoints), research.md (decisions)
+## Operating Constraints
 
-3. **Execute task generation workflow**:
-   - **Architecture Analysis (CRITICAL)**: Scan existing codebase for patterns (DI, Auth, ORM).
-   - Load plan.md/spec.md.
-   - Generate tasks organized by user story.
-   - **Apply Fractal Co-location**: Ensure all unit tests are mapped to `__tests__` subdirectories relative to the code.
-   - Validate task completeness.
+1. **NEVER delete existing tests** - Only update if they fail due to bugs in the test or implementation
+2. **NEVER duplicate tests** - Check existing tests first before creating new ones
+3. **Use TEST_DATA fixtures** - For CRITICAL tier modules, read @TEST_DATA from .ai/standards/semantics.md
+4. **Co-location required** - Write tests in `__tests__` directories relative to the code being tested
 
-4. **Generate tasks.md**: Use `.specify/templates/tasks-template.md` as structure.
-   - Phase 1: Context & Setup.
-   - Phase 2: Foundational tasks.
-   - Phase 3+: User Stories (Priority order).
-   - Final Phase: Polish.
-   - **Strict Constraint**: Ensure tasks follow the Co-location and Mocking rules below.
+## Execution Steps
 
-5. **Report**: Output path to generated tasks.md and summary.
+### 1. Analyze Context
 
-Context for task generation: $ARGUMENTS
+Run `.specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks` from repo root and parse FEATURE_DIR and AVAILABLE_DOCS.
 
-## Task Generation Rules
+Determine:
+- FEATURE_DIR - where the feature is located
+- TASKS_FILE - path to tasks.md
+- Which modules need testing based on task status
 
-**CRITICAL**: Tasks MUST be actionable, specific, architecture-aware, and context-local.
+### 2. Load Relevant Artifacts
 
-### Implementation & Testing Constraints (ANTI-LOOP & CO-LOCATION)
+**From tasks.md:**
+- Identify completed implementation tasks (not test tasks)
+- Extract file paths that need tests
 
-To prevent infinite debugging loops and context fragmentation, apply these rules:
+**From .ai/standards/semantics.md:**
+- Read @TIER annotations for modules
+- For CRITICAL modules: Read @TEST_DATA fixtures
 
-1.  **Fractal Co-location Strategy (MANDATORY)**:
-    - **Rule**: Unit tests MUST live next to the code they verify.
-    - **Forbidden**: Do NOT create unit tests in root `tests/` or `backend/tests/`. Those are for E2E/Integration only.
-    - **Pattern (Python)**:
-      - Source: `src/domain/order/processing.py`
-      - Test Task: `Create tests in src/domain/order/__tests__/test_processing.py`
-    - **Pattern (Frontend)**:
-      - Source: `src/lib/components/UserCard.svelte`
-      - Test Task: `Create tests in src/lib/components/__tests__/UserCard.test.ts`
+**From existing tests:**
+- Scan `__tests__` directories for existing tests
+- Identify test patterns and coverage gaps
 
-2.  **Semantic Relations**:
-    - Test generation tasks must explicitly instruct to add the relation header: `# @RELATION: VERIFIES -> [TargetComponent]`
+### 3. Test Coverage Analysis
 
-3.  **Strict Mocking for Unit Tests**:
-    - Any task creating Unit Tests MUST specify: *"Use `unittest.mock.MagicMock` for heavy dependencies (DB sessions, Auth). Do NOT instantiate real service classes."*
+Create coverage matrix:
 
-4.  **Schema/Model Separation**:
-    - Explicitly separate tasks for ORM Models (SQLAlchemy) and Pydantic Schemas.
+| Module | File | Has Tests | TIER | TEST_DATA Available |
+|--------|------|-----------|------|-------------------|
+| ... | ... | ... | ... | ... |
 
-### UX Preservation (CRITICAL)
+### 4. Write Tests (TDD Approach)
 
-- **Source of Truth**: `ux_reference.md` is the absolute standard.
-- **Verification Task**: You **MUST** add a specific task at the end of each User Story phase: `- [ ] Txxx [USx] Verify implementation matches ux_reference.md (Happy Path & Errors)`
+For each module requiring tests:
 
-### Checklist Format (REQUIRED)
+1. **Check existing tests**: Scan `__tests__/` for duplicates
+2. **Read TEST_DATA**: If CRITICAL tier, read @TEST_DATA from .ai/standards/semantics.md
+3. **Write test**: Follow co-location strategy
+   - Python: `src/module/__tests__/test_module.py`
+   - Svelte: `src/lib/components/__tests__/test_component.test.js`
+4. **Use mocks**: Use `unittest.mock.MagicMock` for external dependencies
 
-Every task MUST strictly follow this format:
+### 4a. UX Contract Testing (Frontend Components)
 
-```text
-- [ ] [TaskID] [P?] [Story?] Description with file path
+For Svelte components with `@UX_STATE`, `@UX_FEEDBACK`, `@UX_RECOVERY` tags:
+
+1. **Parse UX tags**: Read component file and extract all `@UX_*` annotations
+2. **Generate UX tests**: Create tests for each UX state transition
+   ```javascript
+   // Example: Testing @UX_STATE: Idle -> Expanded
+   it('should transition from Idle to Expanded on toggle click', async () => {
+     render(Sidebar);
+     const toggleBtn = screen.getByRole('button', { name: /toggle/i });
+     await fireEvent.click(toggleBtn);
+     expect(screen.getByTestId('sidebar')).toHaveClass('expanded');
+   });
+   ```
+3. **Test @UX_FEEDBACK**: Verify visual feedback (toast, shake, color changes)
+4. **Test @UX_RECOVERY**: Verify error recovery mechanisms (retry, clear input)
+5. **Use @UX_TEST fixtures**: If component has `@UX_TEST` tags, use them as test specifications
+
+**UX Test Template:**
+```javascript
+// [DEF:__tests__/test_Component:Module]
+// @RELATION: VERIFIES -> ../Component.svelte
+// @PURPOSE: Test UX states and transitions
+
+describe('Component UX States', () => {
+  // @UX_STATE: Idle -> {action: click, expected: Active}
+  it('should transition Idle -> Active on click', async () => { ... });
+  
+  // @UX_FEEDBACK: Toast on success
+  it('should show toast on successful action', async () => { ... });
+  
+  // @UX_RECOVERY: Retry on error
+  it('should allow retry on error', async () => { ... });
+});
 ```

-- ❌ `- [ ] T005 [US1] Create tests in backend/tests/test_order.py` (VIOLATION: Wrong location)
+### 5. Test Documentation
 
-### Task Organization & Phase Structure
+Create/update documentation in `specs/<feature>/tests/`:
 
-**Phase 1: Context & Setup**
-- **Goal**: Prepare environment and understand existing patterns.
-- **Mandatory Task**: `- [ ] T001 Analyze existing project structure, auth patterns, and `conftest.py` location`
+```

+```
 
-**Phase 2: Foundational (Data & Core)**
-- Database Models (ORM).
-- Pydantic Schemas (DTOs).
-- Core Service interfaces.
+### 6. Execute Tests
 
-**Phase 3+: User Stories (Iterative)**
-- **Step 1: Isolation Tests (Co-located)**: 
-  - `- [ ] Txxx [USx] Create unit tests for [Component] in [Path]/__tests__/test_[name].py`
-  - *Note: Specify using MagicMock for external deps.*
-- **Step 2: Implementation**: Services -> Endpoints.
-- **Step 3: Integration**: Wire up real dependencies (if E2E tests requested).
-- **Step 4: UX Verification**.
+Run tests and report results:
 
-**Final Phase: Polish**
-- Linting, formatting, final manual verify.
+**Backend:**
+```bash
+cd backend && .venv/bin/python3 -m pytest -v
+```
+
+**Frontend:**
+```bash
+cd frontend && npm run test
+```
+

-# Semantic Code Generation Constitution
-
-## Core Principles
-
-### I. Semantic Protocol Compliance
-The file `semantic_protocol.md` is the **sole and authoritative technical standard** for this project.
-- **Law**: All code must adhere to the Axioms (Meaning First, Contract First, etc.) defined in the Protocol.
-- **Syntax & Structure**: Anchors (`[DEF]`), Tags (`@KEY`), and File Structures must strictly match the Protocol.
-- **Compliance**: Any deviation from `semantic_protocol.md` constitutes a build failure.
-
-### II. Everything is a Plugin & Centralized Config
-All functional extensions, tools, or major features must be implemented as modular Plugins inheriting from `PluginBase`.
-- **Modularity**: Logic should not reside in standalone services or scripts unless strictly necessary for core infrastructure. This ensures a unified execution model via the `TaskManager`.
-- **Configuration Discipline**: All configuration access (environments, settings, paths) MUST use the `ConfigManager`. In the backend, the singleton instance MUST be obtained via dependency injection (`get_config_manager()`). Hardcoding environment IDs (e.g., "1") or paths is STRICTLY FORBIDDEN.
-
-### III. Unified Frontend Experience
-To ensure a consistent and accessible user experience, all frontend implementations must strictly adhere to the unified design and localization standards.
-- **Component Reusability**: All UI elements MUST utilize the standardized Svelte component library (`src/lib/ui`) and centralized design tokens.
-- **Internationalization (i18n)**: All user-facing text MUST be extracted to the translation system (`src/lib/i18n`).
-- **Backend Communication**: All API requests MUST use the `requestApi` wrapper (or its derivatives like `fetchApi`, `postApi`) from `src/lib/api.js`. Direct use of the native `fetch` API for backend communication is FORBIDDEN to ensure consistent authentication (JWT) and error handling.
-
-### IV. Security & Access Control
-To support the Role-Based Access Control (RBAC) system, all functional components must define explicit permissions.
-- **Granular Permissions**: Every Plugin MUST define a unique permission string (e.g., `plugin:name:execute`) required for its operation.
-- **Registration**: These permissions MUST be registered in the system database (`auth.db`) during initialization.
-
-### V. Independent Testability
-Every feature specification MUST define "Independent Tests" that allow the feature to be verified in isolation.
-- **Decoupling**: Features should be designed such that they can be tested without requiring the full application state or external dependencies where possible.
-- **Verification**: A feature is not complete until its Independent Test scenarios pass.
-
-### VI. Asynchronous Execution
-All long-running or resource-intensive operations (migrations, analysis, backups, external API calls) MUST be executed as asynchronous tasks via the `TaskManager`.
-- **Non-Blocking**: HTTP API endpoints MUST NOT block on these operations; they should spawn a task and return a Task ID.
-- **Observability**: Tasks MUST emit real-time status updates via the WebSocket infrastructure.
-
-## Governance
-This Constitution establishes the "Semantic Code Generation Protocol" as the supreme law of this repository.
-
-- **Authoritative Source**: `semantic_protocol.md` defines the specific implementation rules for Principle I.
-- **Amendments**: Changes to core principles require a Constitution amendment. Changes to technical syntax require a Protocol update.
-- **Compliance**: Failure to adhere to the Protocol constitutes a build failure.
-

+
+## Anti-Patterns & Rules
+
+### ✅ DO
+
+1. Write tests BEFORE implementation (TDD approach)
+2. Use co-location: `src/module/__tests__/test_module.py`
+3. Use MagicMock for external dependencies (DB, Auth, APIs)
+4. Include semantic annotations: `# @RELATION: VERIFIES -> module.name`
+5. Test edge cases and error conditions
+6. **Test UX states** for Svelte components (@UX_STATE, @UX_FEEDBACK, @UX_RECOVERY)
+
+### ❌ DON'T
+
+1. Delete existing tests (only update if they fail)
+2. Duplicate tests - check for existing tests first
+3. Test implementation details, not behavior
+4. Use real external services in unit tests
+5. Skip error handling tests
+6. **Skip UX contract tests** for CRITICAL frontend components
+
+---
+
+## UX Contract Testing (Frontend)
+
+### UX States Coverage
+
+| Component | @UX_STATE | @UX_FEEDBACK | @UX_RECOVERY | Tests |
+|-----------|-----------|--------------|--------------|-------|
+| [Component] | [states] | [feedback] | [recovery] | [status] |
+
+### UX Test Cases
+
+| ID | Component | UX Tag | Test Action | Expected Result | Status |
+|----|-----------|--------|-------------|-----------------|--------|
+| UX001 | [Component] | @UX_STATE: Idle | [action] | [expected] | [Pass/Fail] |
+| UX002 | [Component] | @UX_FEEDBACK | [action] | [expected] | [Pass/Fail] |
+| UX003 | [Component] | @UX_RECOVERY | [action] | [expected] | [Pass/Fail] |
+
+### UX Test Examples
+
+```javascript
+// Testing @UX_STATE transition
+it('should transition from Idle to Loading on submit', async () => {
+  render(FormComponent);
+  await fireEvent.click(screen.getByText('Submit'));
+  expect(screen.getByTestId('form')).toHaveClass('loading');
+});
+
+// Testing @UX_FEEDBACK
+it('should show error toast on validation failure', async () => {
+  render(FormComponent);
+  await fireEvent.click(screen.getByText('Submit'));
+  expect(screen.getByRole('alert')).toHaveTextContent('Validation error');
+});
+
+// Testing @UX_RECOVERY
+it('should allow retry after error', async () => {
+  render(FormComponent);
+  // Trigger error state
+  await fireEvent.click(screen.getByText('Submit'));
+  // Click retry
+  await fireEvent.click(screen.getByText('Retry'));
+  expect(screen.getByTestId('form')).not.toHaveClass('error');
+});

+## Docker и CI/CD
+### Локальный запуск в Docker (приложение + PostgreSQL)
+```bash
+docker compose up --build
+```
+
+После старта:
+- UI/API: `http://localhost:8000`
+- PostgreSQL: `localhost:5432` (`postgres/postgres`, DB `ss_tools`)
+
+Остановить:
+```bash
+docker compose down
+```
+
+Полная очистка тома БД:
+```bash
+docker compose down -v
+```
+
+Если `postgres:16-alpine` не тянется из Docker Hub (TLS timeout), используйте fallback image:
+```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 на хосте уже занят `5432`, поднимайте Postgres на другом порту:
+```bash
+POSTGRES_HOST_PORT=5433 docker compose up -d db
+```
+
+### Миграция legacy-данных в PostgreSQL
+Если нужно перенести старые данные из `tasks.db`/`config.json`:
+```bash
+cd backend
+PYTHONPATH=. .venv/bin/python src/scripts/migrate_sqlite_to_postgres.py --sqlite-path tasks.db

 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:
