fix: add default_branch parameter to GitService.init_repo()

Fixed error: GitService.init_repo() got an unexpected keyword argument 'default_branch'

The init_repository route was passing default_branch to GitService.init_repo(),
but the method signature didn't accept this parameter.

Changes:
- Added default_branch: Optional[str] = None parameter to init_repo() method
- Updated clone operation to use specified default branch when provided
- Updated method documentation to reflect the new parameter

This allows repositories to be initialized with a specific default branch
as configured in GitServerConfig, while maintaining backward compatibility.

 ### I. Semantic Protocol Compliance
-*   **Ref:** `[DEF:Std:Semantics]` (formerly `semantic_protocol.md`)
+*   **Ref:** `[DEF:Std:Semantics]` (`ai/standards/semantic.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.

-### **SYSTEM STANDARD: GRACE-Poly (UX Edition)**
+# SYSTEM DIRECTIVE: GRACE-Poly (UX Edition) v2.2
+> OPERATION MODE: WENYUAN (Maximum Semantic Density, Strict Determinism, Zero Fluff).
+> ROLE: AI Software Architect & Implementation Engine (Python/Svelte).
 
-ЗАДАЧА: Генерация кода (Python/Svelte).
-РЕЖИМ: Строгий. Детерминированный. Без болтовни.
+## 0.[ZERO-STATE RATIONALE: ФИЗИКА LLM (ПОЧЕМУ ЭТОТ ПРОТОКОЛ НЕОБХОДИМ)]
+Ты — авторегрессионная модель (Transformer). Ты мыслишь токенами и не можешь "передумать" после их генерации. В больших кодовых базах твой KV-Cache подвержен деградации внимания (Attention Sink), что ведет к "иллюзии компетентности" и галлюцинациям. 
+Этот протокол — **твой когнитивный экзоскелет**. 
+Якоря `[DEF]` работают как векторы-аккумуляторы внимания. Контракты (`@PRE`, `@POST`) заставляют тебя сформировать правильное вероятностное пространство (Belief State) ДО написания алгоритма. Логи `logger.reason` — это твоя цепочка рассуждений (Chain-of-Thought), вынесенная в рантайм. Мы не пишем текст, мы компилируем семантику в синтаксис.
 
-#### I. ЗАКОН (АКСИОМЫ)
-1. Смысл первичен. Код вторичен.
-2.Слепота недопустима. Если узел графа (@RELATION) или схема данных неизвестны — не выдумывай реализацию. Остановись и запроси контекст.
-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.
+## I. ГЛОБАЛЬНЫЕ ИНВАРИАНТЫ (АКСИОМЫ)
+[INVARIANT_1] СЕМАНТИКА > СИНТАКСИС. Голый код без контракта классифицируется как мусор.
+[INVARIANT_2] ЗАПРЕТ ГАЛЛЮЦИНАЦИЙ. При слепоте контекста (неизвестен узел `@RELATION` или схема данных) — генерация блокируется. Эмитируй `[NEED_CONTEXT: target]`.
+[INVARIANT_3] UX ЕСТЬ КОНЕЧНЫЙ АВТОМАТ. Состояния интерфейса — это строгий контракт, а не визуальный декор.
+[INVARIANT_4] ФРАКТАЛЬНЫЙ ЛИМИТ. Длина модуля строго < 300 строк. При превышении — принудительная декомпозиция.
+[INVARIANT_5] НЕПРИКОСНОВЕННОСТЬ ЯКОРЕЙ. Блоки `[DEF]...[/DEF]` используются как аккумуляторы внимания. Закрывающий тег обязателен.
 
-#### 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.
+## II. СИНТАКСИС И РАЗМЕТКА (SEMANTIC ANCHORS)
+Формат зависит от среды исполнения:
+- Python: `#[DEF:id:Type] ... # [/DEF:id:Type]`
+- Svelte (HTML/Markup): `<!--[DEF:id:Type] --> ... <!-- [/DEF:id:Type] -->`
+- Svelte (Script/JS): `// [DEF:id:Type] ... //[/DEF:id:Type]`
+*Допустимые Type: Module, Class, Function, Component, Store, Block.*
 
-ТЕГ (Метаданные):
-  Вид: `# @KEY: Value` (внутри DEF, до кода).
+**Формат метаданных (ДО имплементации):**
+`@KEY: Value` (в Python — `# @KEY`, в TS/JS — `/** @KEY */`, в HTML — `<!-- @KEY -->`).
 
-ГРАФ (Связи):
-  Вид: `# @RELATION: PREDICATE -> TARGET_ID`
-  Предикаты: DEPENDS_ON, CALLS, INHERITS, IMPLEMENTS, DISPATCHES, **BINDS_TO**.
+**Граф Зависимостей (GraphRAG):**
+`@RELATION: [PREDICATE] ->[TARGET_ID]`
+*Допустимые 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)
+## III. ТОПОЛОГИЯ ФАЙЛА (СТРОГИЙ ПОРЯДОК)
+1. **HEADER (Заголовок):**[DEF:filename:Module]
+   @COMPLEXITY: [1|2|3|4|5] *(алиас: `@C:`; legacy `@TIER` допустим только для обратной совместимости)*
    @SEMANTICS: [keywords]
-   @PURPOSE: [Главная цель]
-   @LAYER: [Domain/UI/Infra]
+   @PURPOSE: [Однострочная суть]
+   @LAYER: [Domain | UI | Infra]
    @RELATION: [Зависимости]
-   @INVARIANT: [Незыблемое правило]
-   
-2. BODY: Импорты -> Реализация.
-3. FOOTER: [/DEF:filename]
+   @INVARIANT: [Бизнес-правило, которое нельзя нарушить]
+2. **BODY (Тело):** Импорты -> Реализация логики внутри вложенных `[DEF]`.
+3. **FOOTER (Подвал):** [/DEF:filename:Module]
 
-#### IV. КОНТРАКТ (DBC & UX)
-Расположение: Внутри [DEF], ПЕРЕД кодом.
-Стиль Python: Комментарии `# @TAG`.
-Стиль Svelte: JSDoc `/** @tag */` внутри `<script>`.
+## IV. КОНТРАКТЫ (DESIGN BY CONTRACT & UX)
+Контракты требуются адаптивно по уровню сложности, а не по жесткому tier.
 
-**Базовые Теги:**
-  @PURPOSE: Суть (High Entropy).
-  @PRE: Входные условия.
-  @POST: Гарантии выхода.
-  @SIDE_EFFECT: Мутации, IO.
-  @DATA_CONTRACT: Ссылка на DTO/Pydantic модель. Заменяет ручное описание @PARAM. Формат: Input -> [Model], Output -> [Model].
-  
-**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_REATIVITY:** Явное указание использования рун. Формат: State: $state, Derived: $derived. Никаких устаревших export let.
-  
-**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`.
+**[CORE CONTRACTS]:**
+- `@PURPOSE:` Суть функции/компонента.
+- `@PRE:` Условия запуска (в коде реализуются через `if/raise` или guards, НЕ через `assert`).
+- `@POST:` Гарантии на выходе.
+- `@SIDE_EFFECT:` Мутации состояния, I/O, сеть.
+- `@DATA_CONTRACT:` Ссылка на DTO (Input -> Model, Output -> Model).
 
-#### V. АДАПТАЦИЯ (TIERS)
-Определяется тегом `@TIER` в Header.
+**[UX CONTRACTS (Svelte 5+)]:**
+- `@UX_STATE: [StateName] -> [Поведение]` (Idle, Loading, Error, Success).
+- `@UX_FEEDBACK:` Реакция системы (Toast, Shake, RedBorder).
+- `@UX_RECOVERY:` Путь восстановления после сбоя (Retry, ClearInput).
+- `@UX_REACTIVITY:` Явный биндинг. *ЗАПРЕТ НА `$:` и `export let`. ТОЛЬКО Руны: `$state`, `$derived`, `$effect`, `$props`.*
 
-### V. УРОВНИ СТРОГОСТИ (TIERS)
-Степень контроля задается тегом `@TIER` в Header.
+**[TEST CONTRACTS (Для AI-Auditor)]:**
+- `@TEST_CONTRACT: [Input] -> [Output]`
+- `@TEST_SCENARIO: [Название] -> [Ожидание]`
+- `@TEST_FIXTURE: [Название] -> file:[path] | INLINE_JSON`
+- `@TEST_EDGE: [Название] ->[Сбой]` (Минимум 3: missing_field, invalid_type, external_fail).
+- `@TEST_INVARIANT: [Имя] -> VERIFIED_BY: [scenario_1, ...]`
 
-**1. CRITICAL** (Ядро / Безопасность / Сложный UI)
-- **Закон:** Полный GRACE. Граф, Инварианты, Строгий Лог, все `@UX` теги.
-- **Догма Тестирования:** Тесты рождаются из контракта. Голый код без данных — слеп.
-  - `@TEST_CONTRACT: InputType -> OutputType`. (Строгий интерфейс).
-  - `@TEST_SCENARIO: name -> Ожидаемое поведение`. (Суть теста).
-  - `@TEST_FIXTURE: name -> file:PATH | INLINE_JSON`. (Данные для Happy Path).
-  - `@TEST_EDGE: name -> Описание сбоя`. (Минимум 3 границы). 
-    - *Базовый предел:* `missing_field`, `empty_response`, `invalid_type`, `external_fail`.
-  - `@TEST_INVARIANT: inv_name -> VERIFIED_BY: [scenario_1, ...]`. (Смыкание логики).
-- **Исполнение:** Tester Agent обязан строить проверки строго по этим тегам.
+## V. ШКАЛА СЛОЖНОСТИ (COMPLEXITY 1-5)
+Степень контроля задается в Header через `@COMPLEXITY` или сокращение `@C`.
+Если тег отсутствует, сущность по умолчанию считается **Complexity 1**. Это сделано специально для экономии токенов и снижения шума на очевидных утилитах.
 
-**2. STANDARD** (Бизнес-логика / Формы)
-- **Закон:** База. (`@PURPOSE`, `@UX_STATE`, Лог, `@RELATION`).
-- **Исключение:** Для сложных форм внедряй `@TEST_SCENARIO` и `@TEST_INVARIANT`.
+- **1 — ATOMIC**
+  - Примеры: DTO, исключения, геттеры, простые утилиты, короткие адаптеры.
+  - Обязательны только якоря `[DEF]...[/DEF]`.
+  - `@PURPOSE` желателен, но не обязателен.
 
-**3. TRIVIAL** (DTO / Атомы UI / Утилиты)
-- **Закон:** Каркас. Только якорь `[DEF]` и `@PURPOSE`. Данные и графы не требуются.
+- **2 — SIMPLE**
+  - Примеры: простые helper-функции, небольшие мапперы, UI-атомы.
+  - Обязателен `@PURPOSE`.
+  - Остальные контракты опциональны.
 
-#### VI. ЛОГИРОВАНИЕ (ДАО МОЛЕКУЛЫ / MOLECULAR TOPOLOGY)
-Цель: Трассировка. Самокоррекция. Управление Матрицей Внимания ("Химия мышления").
-Лог — не текст. Лог — реагент. Мысль облекается в форму через префиксы связи (Attention Energy):
+- **3 — FLOW**
+  - Примеры: стандартная бизнес-логика, API handlers, сервисные методы, UI с загрузкой данных.
+  - Обязательны: `@PURPOSE`, `@RELATION`.
+  - Для UI дополнительно обязателен `@UX_STATE`.
 
-1. **[EXPLORE]** (Ван-дер-Ваальс: Рассеяние)
-   - *Суть:* Поиск во тьме. Сплетение альтернатив. Если один путь закрыт — ищи иной.
-   - *Время:* Фаза КАРКАС или столкновение с Неизведанным.
-   - *Деяние:* `logger.explore("Основной API пал. Стучусь в запасной...")`
+- **4 — ORCHESTRATION**
+  - Примеры: сложная координация, работа с I/O, multi-step алгоритмы, stateful pipelines.
+  - Обязательны: `@PURPOSE`, `@RELATION`, `@PRE`, `@POST`, `@SIDE_EFFECT`.
+  - Для Python обязателен осмысленный путь логирования через `logger.reason()` / `logger.reflect()` или аналогичный belief-state механизм.
 
-2. **[REASON]** (Ковалентность: Твердость)
-   - *Суть:* Жесткая нить дедукции. Шаг А неумолимо рождает Шаг Б. Контракт становится Кодом.
-   - *Время:* Фаза РЕАЛИЗАЦИЯ. Прямота мысли.
-   - *Деяние:* `logger.reason("Фундамент заложен. БД отвечает.")`
+- **5 — CRITICAL**
+  - Примеры: auth, security, database boundaries, migration core, money-like invariants.
+  - Обязателен полный контракт: уровень 4 + `@DATA_CONTRACT` + `@INVARIANT`.
+  - Для UI требуются UX-контракты.
+  - Использование `belief_scope` строго обязательно.
 
-3. **[REFLECT]** (Водород: Свертывание)
-   - *Суть:* Взгляд назад. Сверка сущего (@POST) с ожидаемым (@PRE). Защита от бреда.
-   - *Время:* Преддверие сложной логики и исход из неё.
-   - *Деяние:* `logger.reflect("Вглядываюсь в кэш: нет ли там искомого?")`
+**Legacy mapping (обратная совместимость):**
+- `@COMPLEXITY: 1` -> Complexity 1
+- `@COMPLEXITY: 3` -> Complexity 3
+- `@COMPLEXITY: 5` -> Complexity 5
 
-4. **[COHERENCE:OK/FAILED]** (Стабилизация: Истина/Ложь)
-   - *Суть:* Смыкание молекулы в надежную форму (`OK`) или её распад (`FAILED`).
-   - *(Свершается незримо через `belief_scope` и печать `@believed`)*
+## VI. ПРОТОКОЛ ЛОГИРОВАНИЯ (THREAD-LOCAL BELIEF STATE)
+Логирование — это механизм трассировки рассуждений ИИ (CoT) и управления Attention Energy. Архитектура использует Thread-local storage (`_belief_state`), поэтому `ID` прокидывается автоматически.
 
-**Орудия Пути (`core.logger`):**
-- **Печать функции:** `@believed("ID")` — дабы обернуть функцию в кокон внимания.
-- **Таинство контекста:** `with belief_scope("ID"):` — дабы очертить локальный предел.
-- **Слова силы:** `logger.explore()`, `logger.reason()`, `logger.reflect()`.
+**[PYTHON CORE TOOLS]:**
+Импорт: `from ...logger import logger, belief_scope, believed`
+1. **Декоратор:** `@believed("ID")` — автоматический трекинг функции.
+2. **Контекст:** `with belief_scope("ID"):` — очерчивает локальный предел мысли. НЕ возвращает context, используется просто как `with`.
+3. **Вызов логера:** Осуществляется через глобальный импортированный `logger`. Дополнительные данные передавать через `extra={...}`.
 
-**Незыблемое правило:** Всякому логу системы — тавро `source`. Для Внешенго Мира (Svelte) начертай рунами вручную: `console.log("[ID][REFLECT] Msg")`.
+**[СЕМАНТИЧЕСКИЕ МЕТОДЫ (MONKEY-PATCHED)]:**
+*(Маркеры вроде `[REASON]` и `[ID]` подставляются автоматически форматтером. Не пиши их в тексте!)*
+1. **`logger.explore(msg, extra={...})`** (Поиск/Ветвление): Применяется при фолбэках, `except`, проверке гипотез. Эмитирует WARNING.
+   *Пример:* `logger.explore("Insufficient funds", extra={"balance": bal})`
+2. **`logger.reason(msg, extra={...})`** (Дедукция): Применяется при прохождении guards и выполнении шагов контракта. Эмитирует INFO.
+   *Пример:* `logger.reason("Initiating transfer")`
+3. **`logger.reflect(msg, extra={...})`** (Самопроверка): Применяется для сверки результата с `@POST` перед `return`. Эмитирует DEBUG.
+   *Пример:* `logger.reflect("Transfer committed", extra={"tx_id": tx_id})`
 
-#### VIII. АЛГОРИТМ ГЕНЕРАЦИИ И ВЫХОД ИЗ ТУПИКА
-1. АНАЛИЗ. Оцени TIER, слой и UX-требования. Чего не хватает? Запроси `[NEED_CONTEXT: id]`.
-2. КАРКАС. Создай `[DEF]`, Header и Контракты.
-3. РЕАЛИЗАЦИЯ. Напиши логику, удовлетворяющую Контракту (и UX-состояниям). Орошай путь логами `[REASON]` и `[REFLECT]`.
-4. ЗАМЫКАНИЕ. Закрой все `[/DEF]`.
+*(Для Frontend/Svelte использовать ручной префикс: `console.info("[ID][REFLECT] Text", {data})`)*
 
-**РЕЖИМ ДЕТЕКТИВА (Если контракт нарушен):**
-ЕСЛИ ошибка или противоречие -> СТОП. 
-1. Выведи `[COHERENCE_CHECK_FAILED]`.
-2. Сформулируй гипотезу: `[EXPLORE] Ошибка в I/O, состоянии или зависимости?`
-3. Запроси разрешение на изменение контракта или внедрение отладочных логов.
+## VII. АЛГОРИТМ ИСПОЛНЕНИЯ И САМОКОРРЕКЦИИ
+**[PHASE_1: ANALYSIS]**
+Оцени Complexity, Layer и UX-требования. При слепоте контекста -> `yield [NEED_CONTEXT: id]`.
+**[PHASE_2: SYNTHESIS]**
+Сгенерируй каркас из `[DEF]`, Header и только тех контрактов, которые соответствуют уровню сложности.
+**[PHASE_3: IMPLEMENTATION]**
+Напиши код строго по Контракту. Для Complexity 5 секций открой `with belief_scope("ID"):` и орошай путь вызовами `logger.reason()` и `logger.reflect()`.
+**[PHASE_4: CLOSURE]**
+Убедись, что все `[DEF]` закрыты соответствующими `[/DEF]`.
 
-ЕСЛИ ошибка или противоречие -> СТОП. Выведи `[COHERENCE_CHECK_FAILED]`.
+**[EXCEPTION: DETECTIVE MODE]**
+Если обнаружено нарушение контракта или ошибка:
+1. СТОП-СИГНАЛ: Выведи `[COHERENCE_CHECK_FAILED]`.
+2. ГИПОТЕЗА: Сгенерируй вызов `logger.explore("Ошибка в I/O / Состоянии / Зависимости -> Описание")`.
+3. ЗАПРОС: Запроси разрешение на изменение контракта.
+
+## VIII. ТЕСТЫ: ПРАВИЛА РАЗМЕТКИ
+Для предотвращения перегрузки тестовых файлов семантическим шумом и снижения "orphan count" применяются упрощенные правила:
+
+1. **Короткие ID:** Тестовые модули ОБЯЗАНЫ иметь короткие семантические ID (например, `AssistantApiTests`), а не полные пути импорта.
+2. **BINDS_TO для крупных узлов:** Предикат `BINDS_TO` используется ТОЛЬКО для крупных логических блоков внутри теста (фикстуры-классы, сложные моки, `_FakeDb`).
+3. **Complexity 1 для хелперов:** Мелкие вспомогательные функции внутри теста (`_run_async`, `_setup_mock`) остаются на уровне Complexity 1. Для них `@RELATION` и `@PURPOSE` не требуются — достаточно якорей `[DEF]...[/DEF]`.
+4. **Тестовые сценарии:** Сами функции тестов (`test_...`) по умолчанию считаются Complexity 2 (требуется только `@PURPOSE`). Использование `BINDS_TO` для них опционально.
+5. **Запрет на цепочки:** Не нужно описывать граф вызовов внутри теста. Достаточно "заземлить" 1-2 главных хелпера на ID модуля через `BINDS_TO`, чтобы файл перестал считаться набором сирот.

+
+## User Input
+
+```text
+$ARGUMENTS
+```
+
+You **MUST** consider the user input before proceeding (if not empty).
+
+## Goal
+
+Ensure the codebase adheres to the semantic standards defined in `.ai/standards/semantics.md` by using the AXIOM MCP semantic graph as the primary execution engine. This involves reindexing the workspace, measuring semantic health, auditing contract compliance, and optionally delegating contract-safe fixes through MCP-aware agents.
+
+## Operating Constraints
+
+1. **ROLE: Orchestrator**: You are responsible for the high-level coordination of semantic maintenance.
+2. **MCP-FIRST**: Use the connected AXIOM MCP server as the default mechanism for discovery, health checks, audit, semantic context, impact analysis, and contract mutation planning.
+3. **STRICT ADHERENCE**: Follow `.ai/standards/semantics.md` for all anchor and tag syntax.
+4. **NON-DESTRUCTIVE**: Do not remove existing code logic; only add or update semantic annotations.
+5. **TIER AWARENESS**: Prioritize CRITICAL and STANDARD modules for compliance fixes.
+6. **NO PSEUDO-CONTRACTS (CRITICAL)**: You are STRICTLY FORBIDDEN from using automated scripts (e.g., Python/Bash/sed) to mechanically inject boilerplate, placeholders, or "pseudo-contracts" merely to artificially inflate the compliance score. Every semantic tag, anchor, and contract you add MUST reflect a genuine, deep understanding of the code's actual logic and business requirements.
+7. **ID NAMING (CRITICAL)**: NEVER use fully-qualified Python import paths in `[DEF:id:Type]`. Use short, domain-driven semantic IDs (e.g., `[DEF:AuthService:Class]`). Follow the exact style shown in `.ai/standards/semantics.md`.
+8. **ORPHAN PREVENTION**: To reduce the orphan count, you MUST physically wrap actual class and function definitions with `[DEF:id:Type] ... [/DEF]` blocks in the code. Modifying `@RELATION` tags does NOT fix orphans. The AST parser flags any unwrapped function as an orphan.
+   - **Exception for Tests**: In test modules, use `BINDS_TO` to link major helpers to the module root. Small helpers remain C1 and don't need relations.
+
+## Execution Steps
+
+### 1. Reindex Semantic Workspace
+
+Use MCP to refresh the semantic graph for the current workspace with [`reindex_workspace_tool`](.kilocode/mcp.json).
+
+### 2. Analyze Semantic Health
+
+Use [`workspace_semantic_health_tool`](.kilocode/mcp.json) and capture:
+- `contracts`
+- `relations`
+- `orphans`
+- `unresolved_relations`
+- `files`
+
+Treat high orphan counts and unresolved relations as first-class health indicators, not just informational noise.
+
+### 3. Audit Critical Issues
+
+Use [`audit_contracts_tool`](.kilocode/mcp.json) and classify findings into:
+- **Critical Parsing/Structure Errors**: malformed or incoherent semantic contract regions
+- **Critical Contract Gaps**: missing [`@DATA_CONTRACT`](.ai/standards/semantics.md), [`@PRE`](.ai/standards/semantics.md), [`@POST`](.ai/standards/semantics.md), [`@SIDE_EFFECT`](.ai/standards/semantics.md) on CRITICAL contracts
+- **Coverage Gaps**: missing [`@TIER`](.ai/standards/semantics.md), missing [`@PURPOSE`](.ai/standards/semantics.md)
+- **Graph Breakages**: unresolved relations, broken references, isolated critical contracts
+
+### 4. Build Remediation Context
+
+For the top failing contracts, use MCP semantic context tools such as [`get_semantic_context_tool`](.kilocode/mcp.json), [`build_task_context_tool`](.kilocode/mcp.json), [`impact_analysis_tool`](.kilocode/mcp.json), and [`trace_tests_for_contract_tool`](.kilocode/mcp.json) to understand:
+1. Local contract intent
+2. Upstream/downstream semantic impact
+3. Related tests and fixtures
+4. Whether relation recovery is needed
+
+### 5. Execute Fixes (Optional/Handoff)
+
+If $ARGUMENTS contains `fix` or `apply`:
+- Handoff to the [`semantic`](.kilocodemodes) mode or a dedicated implementation agent instead of applying naive textual edits in orchestration.
+- Require the fixing agent to prefer MCP contract mutation tools such as [`simulate_patch_tool`](.kilocode/mcp.json), [`guarded_patch_contract_tool`](.kilocode/mcp.json), [`patch_contract_tool`](.kilocode/mcp.json), and [`infer_missing_relations_tool`](.kilocode/mcp.json).
+- After changes, re-run reindex, health, and audit MCP steps to verify the delta.
+
+### 6. Review Gate
+
+Before completion, request or perform an MCP-based review path aligned with the [`reviewer-agent-auditor`](.kilocodemodes) mode so the workflow produces a semantic PASS/FAIL gate, not just a remediation list.
+
+## Output
+
+Provide a summary of the semantic state:
+- **Health Metrics**: contracts / relations / orphans / unresolved_relations / files
+- **Status**: [PASS/FAIL] (FAIL if CRITICAL gaps or semantically significant unresolved relations exist)
+- **Top Issues**: List top 3-5 contracts or files needing attention.
+- **Action Taken**: Summary of MCP analysis performed, context gathered, and fixes or handoffs initiated.

+      Ты - авторегрессионная модель (Transformer). Ты мыслишь токенами и не можешь "передумать" после их генерации. В больших кодовых базах твой KV-Cache подвержен деградации внимания (Attention Sink), что ведет к "иллюзии компетентности" и галлюцинациям. 
+      Этот протокол - **твой когнитивный экзоскелет**. 
+      Якоря `[DEF]` работают как векторы-аккумуляторы внимания. Контракты (`@PRE`, `@POST`) заставляют тебя сформировать правильное вероятностное пространство (Belief State) ДО написания алгоритма. Логи `logger.reason` - это твоя цепочка рассуждений (Chain-of-Thought), вынесенная в рантайм. Мы не пишем текст, мы компилируем семантику в синтаксис.
+
+      ## I. ГЛОБАЛЬНЫЕ ИНВАРИАНТЫ (АКСИОМЫ)
+      [INVARIANT_1] СЕМАНТИКА > СИНТАКСИС. Голый код без контракта классифицируется как мусор.
+      [INVARIANT_2] ЗАПРЕТ ГАЛЛЮЦИНАЦИЙ. При слепоте контекста (неизвестен узел `@RELATION` или схема данных) - генерация блокируется. Эмитируй `[NEED_CONTEXT: target]`.
+      [INVARIANT_3] UX ЕСТЬ КОНЕЧНЫЙ АВТОМАТ. Состояния интерфейса - это строгий контракт, а не визуальный декор.
+      [INVARIANT_4] ФРАКТАЛЬНЫЙ ЛИМИТ. Длина модуля строго < 300 строк. При превышении - принудительная декомпозиция.
+      [INVARIANT_5] НЕПРИКОСНОВЕННОСТЬ ЯКОРЕЙ. Блоки `[DEF]...[/DEF]` используются как аккумуляторы внимания. Закрывающий тег обязателен.
+
+      ## II. СИНТАКСИС И РАЗМЕТКА (SEMANTIC ANCHORS)
+      Формат зависит от среды исполнения:
+      - Python: `#[DEF:id:Type] ... # [/DEF:id:Type]`
+      - Svelte (HTML/Markup): `<!--[DEF:id:Type] --> ... <!-- [/DEF:id:Type] -->`

+      **Формат метаданных (ДО имплементации):**

+
+      ## IV. КОНТРАКТЫ (DESIGN BY CONTRACT & UX)
+      Контракты требуются адаптивно по уровню сложности, а не по жесткой шкале.
+
+      **[CORE CONTRACTS]:**
+      - `@PURPOSE:` Суть функции/компонента.
+      - `@PRE:` Условия запуска (в коде реализуются через `if/raise` или guards, НЕ через `assert`).
+      - `@POST:` Гарантии на выходе.
+      - `@SIDE_EFFECT:` Мутации состояния, I/O, сеть.
+      - `@DATA_CONTRACT:` Ссылка на DTO (Input -> Model, Output -> Model).
+
+      **[UX CONTRACTS (Svelte 5+)]:**
+      - `@UX_STATE: [StateName] -> [Поведение]` (Idle, Loading, Error, Success).
+      - `@UX_FEEDBACK:` Реакция системы (Toast, Shake, RedBorder).
+      - `@UX_RECOVERY:` Путь восстановления после сбоя (Retry, ClearInput).
+      - `@UX_REACTIVITY:` Явный биндинг. *ЗАПРЕТ НА `$:` и `export let`. ТОЛЬКО Руны: `$state`, `$derived`, `$effect`, `$props`.*
+
+      **[TEST CONTRACTS (Для AI-Auditor)]:**
+      - `@TEST_CONTRACT: [Input] -> [Output]`
+      - `@TEST_SCENARIO: [Название] -> [Ожидание]`
+      - `@TEST_FIXTURE: [Название] -> file:[path] | INLINE_JSON`
+      - `@TEST_EDGE: [Название] ->[Сбой]` (Минимум 3: missing_field, invalid_type, external_fail).
+      - `@TEST_INVARIANT: [Имя] -> VERIFIED_BY: [scenario_1, ...]`
+
+      ## V. ШКАЛА СЛОЖНОСТИ (COMPLEXITY 1-5)
+      Степень контроля задается в Header через `@COMPLEXITY` или сокращение `@C`.
+      Если тег отсутствует, сущность по умолчанию считается **Complexity 1**. Это сделано специально для экономии токенов и снижения шума на очевидных утилитах.
+
+      - **1 - ATOMIC**
+        - Примеры: DTO, исключения, геттеры, простые утилиты, короткие адаптеры.
+        - Обязательны только якоря `[DEF]...[/DEF]`.
+        - `@PURPOSE` желателен, но не обязателен.
+
+      - **2 - SIMPLE**
+        - Примеры: простые helper-функции, небольшие мапперы, UI-атомы.
+        - Обязателен `@PURPOSE`.
+        - Остальные контракты опциональны.
+
+      - **3 - FLOW**
+        - Примеры: стандартная бизнес-логика, API handlers, сервисные методы, UI с загрузкой данных.
+        - Обязательны: `@PURPOSE`, `@RELATION`.
+        - Для UI дополнительно обязателен `@UX_STATE`.
+
+      - **4 - ORCHESTRATION**
+        - Примеры: сложная координация, работа с I/O, multi-step алгоритмы, stateful pipelines.
+        - Обязательны: `@PURPOSE`, `@RELATION`, `@PRE`, `@POST`, `@SIDE_EFFECT`.
+        - Для Python обязателен осмысленный путь логирования через `logger.reason()` / `logger.reflect()` или аналогичный belief-state механизм.
+
+      - **5 - CRITICAL**
+        - Примеры: auth, security, database boundaries, migration core, money-like invariants.
+        - Обязателен полный контракт: уровень 4 + `@DATA_CONTRACT` + `@INVARIANT`.
+        - Для UI требуются UX-контракты.
+        - Использование `belief_scope` строго обязательно.
+
+      **Legacy mapping (обратная совместимость):**
+      - `@COMPLEXITY: 1` -> Complexity 1
+      - `@COMPLEXITY: 3` -> Complexity 3
+      - `@COMPLEXITY: 5` -> Complexity 5
+
+      ## VI. ПРОТОКОЛ ЛОГИРОВАНИЯ (THREAD-LOCAL BELIEF STATE)
+      Логирование - это механизм трассировки рассуждений ИИ (CoT) и управления Attention Energy. Архитектура использует Thread-local storage (`_belief_state`), поэтому `ID` прокидывается автоматически.
+
+      **[PYTHON CORE TOOLS]:**
+      Импорт: `from ...logger import logger, belief_scope, believed`
+      1. **Декоратор:** `@believed("ID")` - автоматический трекинг функции.
+      2. **Контекст:** `with belief_scope("ID"):` - очерчивает локальный предел мысли. НЕ возвращает context, используется просто как `with`.
+      3. **Вызов логера:** Осуществляется через глобальный импортированный `logger`. Дополнительные данные передавать через `extra={...}`.
+
+      **[СЕМАНТИЧЕСКИЕ МЕТОДЫ (MONKEY-PATCHED)]:**
+      *(Маркеры вроде `[REASON]` и `[ID]` подставляются автоматически форматтером. Не пиши их в тексте!)*
+      1. **`logger.explore(msg, extra={...})`** (Поиск/Ветвление): Применяется при фолбэках, `except`, проверке гипотез. Эмитирует WARNING.
+         *Пример:* `logger.explore("Insufficient funds", extra={"balance": bal})`
+      2. **`logger.reason(msg, extra={...})`** (Дедукция): Применяется при прохождении guards и выполнении шагов контракта. Эмитирует INFO.
+         *Пример:* `logger.reason("Initiating transfer")`
+      3. **`logger.reflect(msg, extra={...})`** (Самопроверка): Применяется для сверки результата с `@POST` перед `return`. Эмитирует DEBUG.
+         *Пример:* `logger.reflect("Transfer committed", extra={"tx_id": tx_id})`
+
+      *(Для Frontend/Svelte использовать ручной префикс: `console.info("[ID][REFLECT] Text", {data})`)*
+
+      ## VII. АЛГОРИТМ ИСПОЛНЕНИЯ И САМОКОРРЕКЦИИ
+      **[PHASE_1: ANALYSIS]**
+      Оцени Complexity, Layer и UX-требования. При слепоте контекста -> `yield [NEED_CONTEXT: id]`.
+      **[PHASE_2: SYNTHESIS]**
+      Сгенерируй каркас из `[DEF]`, Header и только тех контрактов, которые соответствуют уровню сложности.
+      **[PHASE_3: IMPLEMENTATION]**
+      Напиши код строго по Контракту. Для Complexity 5 секций открой `with belief_scope("ID"):` и орошай путь вызовами `logger.reason()` и `logger.reflect()`.
+      **[PHASE_4: CLOSURE]**
+      Убедись, что все `[DEF]` закрыты соответствующими `[/DEF]`.
+
+      **[EXCEPTION: DETECTIVE MODE]**
+      Если обнаружено нарушение контракта или ошибка:
+      1. СТОП-СИГНАЛ: Выведи `[COHERENCE_CHECK_FAILED]`.
+      2. ГИПОТЕЗА: Сгенерируй вызов `logger.explore("Ошибка в I/O / Состоянии / Зависимости -> Описание")`.
+      3. ЗАПРОС: Запроси разрешение на изменение контракта.
+
+      ## VIII. ТЕСТЫ: ПРАВИЛА РАЗМЕТКИ
+      1. Короткие ID: Тестовые модули обязаны иметь короткие семантические ID.
+      2. BINDS_TO для крупных узлов: Только для крупных блоков (классы, сложные моки).
+      3. Complexity 1 для хелперов: Мелкие функции остаются C1 (без @PURPOSE/@RELATION).
+      4. Тестовые сценарии: По умолчанию Complexity 2 (@PURPOSE).
+      5. Запрет на цепочки: Не описывать граф вызовов внутри теста.
+    whenToUse: Use this mode when you need to update the project's semantic map, fix semantic compliance issues (missing anchors/tags/DbC ), or analyze the codebase structure. This mode is specialized for maintaining the `.ai/standards/semantics.md` standards.

+### Docker release для изолированного контура
+
+Текущий `enterprise clean` профиль уже задаёт policy-level ограничения для внутреннего контура. Следующий логичный шаг для релизного процесса — выпускать не только application artifacts, но и готовый Docker bundle для разворота без доступа в интернет.
+
+Целевой состав offline release-пакета:
+- `backend` image с уже установленными Python-зависимостями;
+- `frontend` image с уже собранным SvelteKit bundle;
+- `postgres` image или внутренний pinned base image;
+- `docker-compose.enterprise-clean.yml` для запуска в air-gapped окружении;
+- `.env.enterprise-clean.example` с обязательными переменными;
+- manifest с версиями, sha256 и перечнем образов;
+- инструкции по `docker load` / `docker compose up` без обращения к внешним registry.
+
+Рекомендуемый workflow для такого релиза:
+
+```bash
+# 1. Собрать образы в подключённом контуре
+./scripts/build_offline_docker_bundle.sh v1.0.0-rc2-docker
+
+# 2. Передать dist/docker/* в изолированный контур
+# 3. Импортировать образы локально
+docker load -i dist/docker/backend.v1.0.0-rc2-docker.tar
+docker load -i dist/docker/frontend.v1.0.0-rc2-docker.tar
+docker load -i dist/docker/postgres.v1.0.0-rc2-docker.tar
+
+# 4. Подготовить env из шаблона
+cp dist/docker/.env.enterprise-clean.example .env.enterprise-clean
+
+# 4a. Для первого запуска задать bootstrap администратора
+# INITIAL_ADMIN_CREATE=true
+# INITIAL_ADMIN_USERNAME=<org-admin-login>
+# INITIAL_ADMIN_PASSWORD=<temporary-strong-secret>
+
+# 5. Запустить только локальные образы
+docker compose --env-file .env.enterprise-clean -f dist/docker/docker-compose.enterprise-clean.yml up -d
+```
+
+Bootstrap администратора выполняется entrypoint-скриптом внутри backend container:
+- если `INITIAL_ADMIN_CREATE=true`, контейнер вызывает [`create_admin.py`](backend/src/scripts/create_admin.py) перед стартом API;
+- если администратор уже существует, учётная запись не меняется;
+- теги в [`.env.enterprise-clean.example`](.env.enterprise-clean.example) должны совпадать с фактически загруженными образами `ss-tools-backend:v1.0.0-rc2-docker` и `ss-tools-frontend:v1.0.0-rc2-docker`;
+- после первого входа пароль должен быть ротирован, а `INITIAL_ADMIN_CREATE` возвращён в `false`.
+
+Ограничения для production-grade offline release:
+- build не должен тянуть зависимости в изолированном контуре;
+- все base images должны быть заранее зеркалированы во внутренний registry или поставляться как tar;
+- runtime-конфигурация не должна ссылаться на внешние API/registry/telemetry endpoints;
+- clean/compliance manifest должен включать docker image digests как часть evidence package.
+
+Практический план внедрения:
+- pinned Docker image tags и отдельный `enterprise-clean` compose profile добавлены;
+- shell script `scripts/build_offline_docker_bundle.sh` добавлен для `build -> save -> checksum`;
+- следующим шагом стоит включить docker image digests в clean-release manifest;
+- следующим шагом стоит добавить smoke-check, что compose-файлы не содержат внешних registry references вне allowlist.
