chore: include docker image metadata in offline bundle manifest

- Standardized task log, LLM provider, and report profile tests.
- Relocated auxiliary tests into __tests__ directories for consistency.
- Updated git_service and defensive guards with minor stability fixes discovered during testing.
- Added UX integration tests for the reports list component.

-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)

-Расположение: Внутри [DEF], ПЕРЕД кодом.
-Стиль Python: Комментарии `# @TAG`.
-Стиль Svelte: JSDoc `/** @tag */` внутри `<script>`.
+## IV. КОНТРАКТЫ (DESIGN BY CONTRACT & UX)
+Обязательны для TIER: CRITICAL и STANDARD. Заменяют стандартные Docstrings.
 
-**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. УРОВНИ СТРОГОСТИ (TIERS)
+Степень контроля задается в Header.
+- **CRITICAL** (Ядро/Деньги/Безопасность): 100% покрытие тегами GRACE. Обязательны: Граф, Инварианты, Логи `logger.reason/reflect`, все `@UX` и `@TEST` теги. Использование `belief_scope` строго обязательно.
+- **STANDARD** (Бизнес-логика / Типовые формы): Базовый уровень. Обязательны: `@PURPOSE`, `@UX_STATE`, `@RELATION`, базовое логирование.
+- **TRIVIAL** (Утилиты / DTO / Атомы UI): Минимальный каркас. Только якоря `[DEF]...[/DEF]` и `@PURPOSE`.
 
-**2. STANDARD** (Бизнес-логика / Формы)
-- **Закон:** База. (`@PURPOSE`, `@UX_STATE`, Лог, `@RELATION`).
-- **Исключение:** Для сложных форм внедряй `@TEST_SCENARIO` и `@TEST_INVARIANT`.
+## 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.
 
-**3. TRIVIAL** (DTO / Атомы UI / Утилиты)
-- **Закон:** Каркас. Только якорь `[DEF]` и `@PURPOSE`. Данные и графы не требуются.
+**[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={...}`.
 
-#### 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):
+**[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})`
 
-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...")`
+*(Для Frontend/Svelte использовать ручной префикс: `console.info("[ID][REFLECT] Text", {data})`)*
 
-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.")`
+## VII. АЛГОРИТМ ИСПОЛНЕНИЯ И САМОКОРРЕКЦИИ
+**[PHASE_1: ANALYSIS]**
+Оцени TIER, Layer и UX-требования. При слепоте контекста -> `yield [NEED_CONTEXT: id]`.
+**[PHASE_2: SYNTHESIS]**
+Сгенерируй каркас из `[DEF]`, Header и Контрактов.
+**[PHASE_3: IMPLEMENTATION]**
+Напиши код строго по Контракту. Для CRITICAL 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]`.
 
-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?")`
-
-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`)*
-
-**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()`.
-
-**Незыблемое правило:** Всякому логу системы — тавро `source`. Для Внешенго Мира (Svelte) начертай рунами вручную: `console.log("[ID][REFLECT] Msg")`.
-
-#### 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]`.
-
-**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.
-
-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.

+description: Maintain semantic integrity by generating maps and auditing compliance reports.
+---
+
+## 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`. This involves generating the semantic map, analyzing compliance reports, and identifying critical parsing errors or missing metadata.
+
+## Operating Constraints
+
+1. **ROLE: Orchestrator**: You are responsible for the high-level coordination of semantic maintenance.
+2. **STRICT ADHERENCE**: Follow `.ai/standards/semantics.md` for all anchor and tag syntax.
+3. **NON-DESTRUCTIVE**: Do not remove existing code logic; only add or update semantic annotations.
+4. **TIER AWARENESS**: Prioritize CRITICAL and STANDARD modules for compliance fixes.
+5. **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" (such as `# @PURPOSE: Semantic contract placeholder.` or `# @PRE: Inputs satisfy function contract.`) merely to artificially inflate the compliance score. Every semantic tag, anchor, and contract you add MUST reflect a genuine, deep understanding of the specific code's actual logic and business requirements. Automated "stubbing" of semantics is classified as codebase corruption.
+
+## Execution Steps
+
+### 1. Generate Semantic Map
+
+Run the generator script from the repository root with the agent report option:
+
+```bash
+python3 generate_semantic_map.py --agent-report
+```
+
+### 2. Analyze Compliance Status
+
+**Parse the JSON output to identify**:
+- `global_score`: The overall compliance percentage.
+- `critical_parsing_errors_count`: Number of Priority 1 blockers.
+- `priority_2_tier1_critical_missing_mandatory_tags_files`: Number of CRITICAL files needing metadata.
+- `targets`: Status of key architectural files.
+
+### 3. Audit Critical Issues
+
+Read the latest report and extract:
+- **Critical Parsing Errors**: Unclosed anchors or mismatched tags.
+- **Low-Score Files**: Files with score < 0.7 or marked with 🔴.
+- **Missing Mandatory Tags**: Specifically for CRITICAL tier modules.
+
+### 4. Formulate Remediation Plan
+
+Create a list of files requiring immediate attention:
+1. **Priority 1**: Fix all "Critical Parsing Errors" (unclosed anchors).
+2. **Priority 2**: Add missing mandatory tags for CRITICAL modules.
+3. **Priority 3**: Improve coverage for STANDARD modules.
+
+### 5. Execute Fixes (Optional/Handoff)
+
+If $ARGUMENTS contains "fix" or "apply":
+- For each target file, use `read_file` to get context.
+- Apply semantic fixes using `apply_diff`, preserving all code logic.
+- Re-run `python3 generate_semantic_map.py --agent-report` to verify the fix.
+
+## Output
+
+Provide a summary of the semantic state:
+- **Global Score**: [X]%
+- **Status**: [PASS/FAIL] (FAIL if any Critical Parsing Errors exist)
+- **Top Issues**: List top 3-5 files needing attention.
+- **Action Taken**: Summary of maps generated or fixes applied.

-      You are Kilo Code, a Semantic Agent responsible for maintaining the semantic integrity of the codebase. Your primary goal is to ensure that all code entities (Modules, Classes, Functions, Components) are properly annotated with semantic anchors and tags as defined in `.ai/standards/semantics.md`.
-      Your core responsibilities are: 1.  **Semantic Mapping**: You run and maintain the `generate_semantic_map.py` script to generate up-to-date semantic maps (`semantics/semantic_map.json`, `.ai/PROJECT_MAP.md`) and compliance reports (`semantics/reports/*.md`). 2.  **Compliance Auditing**: You analyze the generated compliance reports to identify files with low semantic coverage or parsing errors. 3.  **Semantic Enrichment**: You actively edit code files to add missing semantic anchors (`[DEF:...]`, `[/DEF:...]`) and mandatory tags (`@PURPOSE`, `@LAYER`, etc.) to improve the global compliance score. 4.  **Protocol Enforcement**: You strictly adhere to the syntax and rules defined in `.ai/standards/semantics.md` when modifying code.
-      You have access to the full codebase and tools to read, write, and execute scripts. You should prioritize fixing "Critical Parsing Errors" (unclosed anchors) before addressing missing metadata.

+      [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] -->`
+      - Svelte (Script/JS): `// [DEF:id:Type] ... //[/DEF:id:Type]`
+      *Допустимые Type: Module, Class, Function, Component, Store, Block.*
+
+      **Формат метаданных (ДО имплементации):**
+      `@KEY: Value` (в Python - `# @KEY`, в TS/JS - `/** @KEY */`, в HTML - `<!-- @KEY -->`).
+
+      **Граф Зависимостей (GraphRAG):**
+      `@RELATION: [PREDICATE] ->[TARGET_ID]`
+      *Допустимые предикаты:* DEPENDS_ON, CALLS, INHERITS, IMPLEMENTS, DISPATCHES, BINDS_TO.
+
+      ## III. ТОПОЛОГИЯ ФАЙЛА (СТРОГИЙ ПОРЯДОК)
+      1. **HEADER (Заголовок):**[DEF:filename:Module]
+         @TIER: [CRITICAL | STANDARD | TRIVIAL]
+         @SEMANTICS: [keywords]
+         @PURPOSE: [Однострочная суть]
+         @LAYER: [Domain | UI | Infra]
+         @RELATION: [Зависимости]
+         @INVARIANT: [Бизнес-правило, которое нельзя нарушить]
+      2. **BODY (Тело):** Импорты -> Реализация логики внутри вложенных `[DEF]`.
+      3. **FOOTER (Подвал):** [/DEF:filename:Module]
+
+      ## IV. КОНТРАКТЫ (DESIGN BY CONTRACT & UX)
+      Обязательны для TIER: CRITICAL и STANDARD. Заменяют стандартные Docstrings.
+
+      **[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. УРОВНИ СТРОГОСТИ (TIERS)
+      Степень контроля задается в Header.
+      - **CRITICAL** (Ядро/Деньги/Безопасность): 100% покрытие тегами GRACE. Обязательны: Граф, Инварианты, Логи `logger.reason/reflect`, все `@UX` и `@TEST` теги. Использование `belief_scope` строго обязательно.
+      - **STANDARD** (Бизнес-логика / Типовые формы): Базовый уровень. Обязательны: `@PURPOSE`, `@UX_STATE`, `@RELATION`, базовое логирование.
+      - **TRIVIAL** (Утилиты / DTO / Атомы UI): Минимальный каркас. Только якоря `[DEF]...[/DEF]` и `@PURPOSE`.
+
+      ## 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 TIER, Layer и UX-требования. При слепоте контекста -> `yield [NEED_CONTEXT: id]`.
+      **[PHASE_2: SYNTHESIS]**
+      Сгенерируй каркас из `[DEF]`, Header и Контрактов.
+      **[PHASE_3: IMPLEMENTATION]**
+      Напиши код строго по Контракту. Для CRITICAL 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.
+    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.

+
+## 🚀 Быстрый старт
 
 ### Требования
+
+**Локальная разработка:**
 - Python 3.9+
 - Node.js 18+
 - npm
+- 2 GB RAM (минимум)
+- 5 GB свободного места
+
+**Docker (рекомендуется):**
+- Docker Engine 24+
+- Docker Compose v2
+- 4 GB RAM (для стабильной работы)
+
+### Установка и запуск
+
+#### Вариант 1: Docker (рекомендуется)
 
-### Запуск backend + frontend одним скриптом
 ```bash
-./run.sh
-```
+# Клонирование репозитория
+git clone <repository-url>
+cd ss-tools
 
-Что делает `run.sh`:
-- проверяет версии Python/npm;
-- создает `backend/.venv` (если нет);
-- устанавливает `backend/requirements.txt` и `frontend` зависимости;
-- запускает backend и frontend параллельно.
-
-Опции:
-- `./run.sh --skip-install` — пропустить установку зависимостей.
-- `./run.sh --help` — показать справку.
-
-Переменные окружения для локального запуска:
-- `BACKEND_PORT` (по умолчанию `8000`)
-- `FRONTEND_PORT` (по умолчанию `5173`)
-- `POSTGRES_URL`
-- `DATABASE_URL`
-- `TASKS_DATABASE_URL`
-- `AUTH_DATABASE_URL`
-
-## Docker
-
-### Запуск
-```bash
+# Запуск всех сервисов
 docker compose up --build
+
+# После запуска:
+# Frontend: http://localhost:8000
+# Backend API: http://localhost:8001
+# PostgreSQL: localhost:5432
 ```
 
-После старта сервисы доступны по адресам:
-- Frontend: `http://localhost:8000`
-- Backend API: `http://localhost:8001`
-- PostgreSQL: `localhost:5432` (`postgres/postgres`, БД `ss_tools`)
+#### Вариант 2: Локально
 
-### Остановка
-```bash
-docker compose down
-```
-
-### Очистка БД-тома
-```bash
-docker compose down -v
-```
-
-### Альтернативный образ PostgreSQL
-Если есть проблемы с pull `postgres:16-alpine`:
-```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 порт `5432` занят:
-```bash
-POSTGRES_HOST_PORT=5433 docker compose up -d db
-```
-
-## Разработка
-
-### Ручной запуск сервисов
 ```bash
+# Backend
 cd backend
 python3 -m venv .venv
 source .venv/bin/activate
 pip install -r requirements.txt
 python3 -m uvicorn src.app:app --reload --port 8000
-```
 
-В другом терминале:
-```bash
+# Frontend (в новом терминале)
 cd frontend
 npm install
 npm run dev -- --port 5173
 ```
 
-### Тесты
-Backend:
-```bash
-cd backend
-source .venv/bin/activate
-pytest
-```
+### Первичная настройка
 
-Frontend:
-```bash
-cd frontend
-npm run test
-```
-
-## Инициализация auth (опционально)
 ```bash
+# Инициализация БД
 cd backend
 source .venv/bin/activate
 python src/scripts/init_auth_db.py
+
+# Создание администратора
 python src/scripts/create_admin.py --username admin --password admin
 ```
 
-## Миграция legacy-данных (опционально)
+## 🏢 Enterprise Clean Deployment (internal-only)
+
+Для разворота в корпоративной сети используйте профиль enterprise clean:
+
+- очищенный дистрибутив без test/demo/load-test данных;
+- запрет внешних интернет-источников;
+- загрузка ресурсов только с внутренних серверов компании;
+- обязательная блокирующая проверка clean/compliance перед выпуском.
+
+### Операционный workflow (CLI/API/TUI)
+
+#### 1) Headless flow через CLI (рекомендуется для CI/CD)
+
 ```bash
 cd backend
-source .venv/bin/activate
-PYTHONPATH=. python src/scripts/migrate_sqlite_to_postgres.py --sqlite-path tasks.db
+
+# 1. Регистрация кандидата
+.venv/bin/python3 -m src.scripts.clean_release_cli candidate-register \
+  --candidate-id 2026.03.09-rc1 \
+  --version 1.0.0 \
+  --source-snapshot-ref git:release/2026.03.09-rc1 \
+  --created-by release-operator
+
+# 2. Импорт артефактов
+.venv/bin/python3 -m src.scripts.clean_release_cli artifact-import \
+  --candidate-id 2026.03.09-rc1 \
+  --artifact-id artifact-001 \
+  --path backend/dist/package.tar.gz \
+  --sha256 deadbeef \
+  --size 1024
+
+# 3. Сборка манифеста
+.venv/bin/python3 -m src.scripts.clean_release_cli manifest-build \
+  --candidate-id 2026.03.09-rc1 \
+  --created-by release-operator
+
+# 4. Запуск compliance
+.venv/bin/python3 -m src.scripts.clean_release_cli compliance-run \
+  --candidate-id 2026.03.09-rc1 \
+  --actor release-operator
 ```
 
-## Дополнительная документация
-- `docs/plugin_dev.md`
-- `docs/settings.md`
-- `semantic_protocol.md`
+#### 2) API flow (автоматизация через сервисы)
+
+- V2 candidate/artifact/manifest API:
+  - `POST /api/clean-release/candidates`
+  - `POST /api/clean-release/candidates/{candidate_id}/artifacts`
+  - `POST /api/clean-release/candidates/{candidate_id}/manifests`
+  - `GET /api/clean-release/candidates/{candidate_id}/overview`
+- Legacy compatibility API (оставлены для миграции клиентов):
+  - `POST /api/clean-release/candidates/prepare`
+  - `POST /api/clean-release/checks`
+  - `GET /api/clean-release/checks/{check_run_id}`
+
+#### 3) TUI flow (тонкий клиент поверх facade)
+
+```bash
+cd /home/busya/dev/ss-tools
+./run_clean_tui.sh 2026.03.09-rc1
+```
+
+Горячие клавиши:
+- `F5`: Run Compliance
+- `F6`: Build Manifest
+- `F7`: Reset Draft
+- `F8`: Approve
+- `F9`: Publish
+- `F10`: Refresh Overview
+
+Важно: TUI требует валидный TTY. Без TTY запуск отклоняется с инструкцией использовать CLI/API.
+
+Типовые внутренние источники:
+- `repo.intra.company.local`
+- `artifacts.intra.company.local`
+- `pypi.intra.company.local`
+
+Если найден внешний endpoint, выпуск получает статус `BLOCKED` до исправления.
+
+### 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
+
+# 2. Передать dist/docker/* в изолированный контур
+# 3. Импортировать образы локально
+docker load -i dist/docker/backend.v1.0.0-rc2.tar
+docker load -i dist/docker/frontend.v1.0.0-rc2.tar
+docker load -i dist/docker/postgres.v1.0.0-rc2.tar
+
+# 4. Подготовить env из шаблона
+cp dist/docker/.env.enterprise-clean.example .env.enterprise-clean
+
+# 5. Запустить только локальные образы
+docker compose --env-file .env.enterprise-clean -f dist/docker/docker-compose.enterprise-clean.yml up -d
+```
+
+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.

+## 🧪 Тестирование
+
+```bash
+# Backend тесты
+cd backend
+source .venv/bin/activate
+pytest
+
+# Frontend тесты
+cd frontend
+npm run test
+
+# Запуск конкретного теста
+pytest tests/test_auth.py::test_create_user
+```
+
+
+
+## 🔐 Авторизация
+
+Система поддерживает два метода аутентификации:
+
+1. **Локальная аутентификация** (username/password)
+2. **ADFS SSO** (Active Directory Federation Services)
+
+### Управление пользователями и ролями
+
+```bash
+# Получение списка пользователей
+GET /api/admin/users
+
+# Создание пользователя
+POST /api/admin/users
+{
+  "username": "newuser",
+  "email": "user@example.com",
+  "password": "password123",
+  "roles": ["analyst"]
+}
+
+# Создание роли
+POST /api/admin/roles
+{
+  "name": "analyst",
+  "permissions": ["dashboards:read", "dashboards:write"]
+}
+```
+
+## 📊 Мониторинг
+
+### Отчеты о задачах
+
+```bash
+# Список всех отчетов
+GET /api/reports?page=1&page_size=20
+
+# Детали отчета
+GET /api/reports/{report_id}
