 # [DEF:Std:API_FastAPI:Standard]
 # @TIER: CRITICAL
 # @PURPOSE: Unification of all FastAPI endpoints following GRACE-Poly.
 # @LAYER: UI (API)
 # @INVARIANT: All non-trivial route logic must be wrapped in `belief_scope`.
 # @INVARIANT: Every module and function MUST have `[DEF:]` anchors and metadata.
 ## 1. ROUTE MODULE DEFINITION
 Every API route file must start with a module definition header:
 ```python
 # [DEF:ModuleName:Module]
 # @TIER: [CRITICAL | STANDARD | TRIVIAL]
 # @SEMANTICS: list, of, keywords
 # @PURPOSE: High-level purpose of the module.
 # @LAYER: UI (API)
 # @RELATION: DEPENDS_ON -> [OtherModule]
 ```
 ## 2. FUNCTION DEFINITION & CONTRACT
 Every endpoint handler must be decorated with `[DEF:]` and explicit metadata before the implementation:
 ```python
@router.post("/endpoint", response_model=ModelOut)
 # [DEF:function_name:Function]
 # @PURPOSE: What it does (brief, high-entropy).
 # @PARAM: param_name (Type) - Description.
 # @PRE: Conditions before execution (e.g., auth, existence).
 # @POST: Expected state after execution.
 # @RETURN: What it returns.
 async def function_name(...):
    with belief_scope("function_name"):
        # Implementation
        pass
 # [/DEF:function_name:Function]
 ```
 ## 3. DEPENDENCY INJECTION & CORE SERVICES
 *   **Auth:** `Depends(get_current_user)` for authentication.
 *   **Perms:** `Depends(has_permission("resource", "ACTION"))` for RBAC.
 *   **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.
 *   Use `try-except` blocks within `belief_scope` to ensure proper error logging and classification.
 *   Do not leak internal implementation details in error responses.

 # @TIER: CRITICAL
 # @PURPOSE: Core architectural decisions and service boundaries.
 # @LAYER: Infra
 # @INVARIANT: ss-tools MUST remain a standalone service (Orchestrator).
 # @INVARIANT: Backend: FastAPI, Frontend: SvelteKit.
 ## 1. ORCHESTRATOR VS INSTANCE
 *   **Role:** ss-tools is a "Manager of Managers". It sits ABOVE Superset environments.
 *   **Isolation:** Do not integrate directly into Superset as a plugin to maintain multi-environment management capability.
 *   **Tech Stack:** 
    *   Backend: Python 3.9+ with FastAPI (Asynchronous logic).
    *   Frontend: SvelteKit + Tailwind CSS (Reactive UX).
 ## 2. COMPONENT BOUNDARIES
 *   **Plugins:** All business logic must be encapsulated in Plugins (`backend/src/plugins/`).
 *   **TaskManager:** All long-running operations MUST be handled by the TaskManager.
 *   **Security:** Independent RBAC system managed in `auth.db`.
 ## 3. INTEGRATION STRATEGY
 *   **Superset API:** Communication via REST API.
 *   **Database:** Local SQLite for metadata (`tasks.db`, `auth.db`, `migrations.db`).
 *   **Filesystem:** Local storage for backups and git repositories.

 # [DEF:Std:Constitution:Standard]
 # @TIER: CRITICAL
 # @PURPOSE: Supreme Law of the Repository. High-level architectural and business invariants.
 # @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`.

 ### **SYSTEM STANDARD: GRACE-Poly (UX Edition)**
 ЗАДАЧА: Генерация кода (Python/Svelte).
 РЕЖИМ: Строгий. Детерминированный. Без болтовни.
 #### I. ЗАКОН (АКСИОМЫ)
 1. Смысл первичен. Код вторичен.
 2. Контракт (@PRE/@POST) — источник истины.
 **3. UX — это логика, а не декор. Состояния интерфейса — часть контракта.**
 4. Структура `[DEF]...[/DEF]` — нерушима.
 5. Архитектура в Header — неизменяема.
 6. Сложность фрактала ограничена: модуль < 300 строк.
 #### II. СИНТАКСИС (ЖЕСТКИЙ ФОРМАТ)
 ЯКОРЬ (Контейнер):
  Начало: `# [DEF:id:Type]` (Python) | `<!-- [DEF:id:Type] -->` (Svelte)
  Конец:  `# [/DEF:id:Type]` (Python) | `<!-- [/DEF:id:Type] -->` (Svelte) (ОБЯЗАТЕЛЬНО для аккумуляции)
  Типы:   Module, Class, Function, Component, Store.
 ТЕГ (Метаданные):
  Вид: `# @KEY: Value` (внутри DEF, до кода).
 ГРАФ (Связи):
  Вид: `# @RELATION: PREDICATE -> TARGET_ID`
  Предикаты: DEPENDS_ON, CALLS, INHERITS, IMPLEMENTS, DISPATCHES, **BINDS_TO**.
 #### III. СТРУКТУРА ФАЙЛА
 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
 - Total Failed Tests: [X]
 - Total Fixed: [X]
 - Total Skipped: [X]
 ## Failed Tests Analysis
 ### Test: [Test Name]
 **File**: `path/to/test.py`
 **Error**: [Error message]
 **Root Cause**: [Explanation of why test failed]
 **Fix Required**: [Description of fix]
 **Status**: [Pending/In Progress/Completed]
 ## Fixes Applied
 ### 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
 ## Summary
 - Total Failed Tests: [X]
 - Total Fixed: [X] ✅
 - Total Skipped: [X]
 ## Fixes Applied
 ### Fix 1: [Description] ✅
 **Affected File**: `path/to/file.py`
 **Test Affected**: `[Test Name]`
 **Changes**: [Summary of changes]
 **Verification**: All tests pass ✅
 **Semantic Integrity**: Preserved ✅
 ## Test Results
 ```
 [Full test output showing all passing tests]
 ```
 ## Recommendations
 - [ ] Monitor for similar issues
 - [ ] Update documentation if needed
 - [ ] Consider adding more tests for edge cases

-   - Generate tasks organized by user story.
+4. **Co-location required** - Write tests in `__tests__` directories relative to the code being tested
   - **Apply Fractal Co-location**: Ensure all unit tests are mapped to `__tests__` subdirectories relative to the code.
   - Validate task completeness.
-4. **Generate tasks.md**: Use `.specify/templates/tasks-template.md` as structure.
+## Execution Steps
   - 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.
-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)**:
+**From existing tests:**
-    - **Rule**: Unit tests MUST live next to the code they verify.
+- Scan `__tests__` directories for existing tests
-    - **Forbidden**: Do NOT create unit tests in root `tests/` or `backend/tests/`. Those are for E2E/Integration only.
+- Identify test patterns and coverage gaps
    - **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`
-2.  **Semantic Relations**:
+### 3. Test Coverage Analysis
    - Test generation tasks must explicitly instruct to add the relation header: `# @RELATION: VERIFIES -> [TargetComponent]`
-3.  **Strict Mocking for Unit Tests**:
+Create coverage matrix:
    - Any task creating Unit Tests MUST specify: *"Use `unittest.mock.MagicMock` for heavy dependencies (DB sessions, Auth). Do NOT instantiate real service classes."*
-4.  **Schema/Model Separation**:
+| Module | File | Has Tests | TIER | TEST_DATA Available |
-    - Explicitly separate tasks for ORM Models (SQLAlchemy) and Pydantic Schemas.
+|--------|------|-----------|------|-------------------|
 | ... | ... | ... | ... | ... |
-### UX Preservation (CRITICAL)
+### 4. Write Tests (TDD Approach)
- **Source of Truth**: `ux_reference.md` is the absolute standard.
+For each module requiring tests:
 - **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)`
-### 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
+For Svelte components with `@UX_STATE`, `@UX_FEEDBACK`, `@UX_RECOVERY` tags:
- [ ] [TaskID] [P?] [Story?] Description with file path
+
 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 () => { ... });
 });
 ```

 - ✅ `- [ ] T006 [US1] Implement OrderService in src/services/order.py`
 - ❌ `- [ ] T005 [US1] Create tests in backend/tests/test_order.py` (VIOLATION: Wrong location)
-### Task Organization & Phase Structure
+Create/update documentation in `specs/<feature>/tests/`:
-**Phase 1: Context & Setup**
+```
- **Goal**: Prepare environment and understand existing patterns.
+tests/
- **Mandatory Task**: `- [ ] T001 Analyze existing project structure, auth patterns, and `conftest.py` location`

-**Phase 2: Foundational (Data & Core)**
+### 6. Execute Tests
 - Database Models (ORM).
 - Pydantic Schemas (DTOs).
 - Core Service interfaces.
-**Phase 3+: User Stories (Iterative)**
+Run tests and report results:
 - **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**.
-**Final Phase: Polish**
+**Backend:**
- Linting, formatting, final manual verify.
+```bash
 cd backend && .venv/bin/python3 -m pytest -v
 ```
 **Frontend:**
 ```bash
 cd frontend && npm run test
 ```
 ### 7. Update Tasks
 Mark test tasks as completed in tasks.md with:
 - Test file path
 - Coverage achieved
 - Any issues found
 ## Output

 # 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.
 - **Tailwind CSS First**: All styling MUST be implemented using Tailwind CSS utility classes. The use of scoped `<style>` blocks in Svelte components MUST be minimized and reserved only for complex animations or third-party overrides that cannot be achieved via Tailwind.
 - **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.
 **Version**: 2.3.0 | **Ratified**: 2025-12-19 | **Last Amended**: 2026-02-18

 ## Knowledge Graph (GRACE)
 **CRITICAL**: This project uses a GRACE Knowledge Graph for context. Always load the root map first:
 - **Root Map**: `.ai/ROOT.md` -> `[DEF:Project_Knowledge_Map:Root]`
 - **Project Map**: `.ai/PROJECT_MAP.md` -> `[DEF:Project_Map]`
 - **Standards**: Read `.ai/standards/` for architecture and style rules.

 ## 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 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

 // Testing @UX_STATE transition
 it('should transition from Idle to Loading on submit', async () => {
  render(FormComponent);
  await fireEvent.click(screen.getByText('Submit'));

 ## 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
 ```
 ### CI/CD
 Добавлен workflow: `.github/workflows/ci-cd.yml`
 - backend smoke tests
 - frontend build
 - docker build
 - push образа в GHCR на `main/master`
 ## Контакты и вклад
 Для добавления новых функций или исправления ошибок, пожалуйста, ознакомьтесь с `docs/plugin_dev.md` и создайте соответствующую спецификацию в `specs/`.
