+# Отчёт о выполнении: Hermes Hub — Release Recovery + GitHub Auto Update
+
+**Дата**: 2026-08-20  
+**Проект**: Hermes Hub  
+**Репозиторий**: `https://github.com/ochenstarik-ui/hermes-hub` (Private)  
+**Релизная версия**: `0.1.1`  
+**Статус Release Gate**: **PASS (6/6 проверок пройдено)**  
+
+---
+
+## 1. Выполненные задачи и статус блокеров (P0)
+
+1. **P0-1 (customtkinter / Pillow)**: `installer/HermesHubSetup.py` проверяет venv Hermes Agent, устанавливает недостающие GUI-зависимости и верифицирует импорты до завершения установки.
+2. **P0-2 (ProfileAuthManager.get_profile_dir)**: Унифицирована сигнатура метода `get_profile_dir`, поддерживающая как 1, так и 2 аргумента, с делегированием в `paths.py`.
+3. **P0-3 (Wizard json import)**: В `add_account_wizard.py` добавлен импорт `json`, процесс сохранения API-ключей полностью покрыт тестами.
+4. **P0-4 (AutoAssigner.auto_assign_all)**: Реализован метод `auto_assign_all()`, автоматически распределяющий авторизованные профили по ключевым ролям команды.
+5. **P0-5 (Antigravity failover)**: Исправлен `_error_completion` в `agy_subprocess.py` и `AntigravityAdapter`. При ошибке квоты (429 / resource exhausted) генерируется типизированный `QuotaExceededError`, RouterEngine фиксирует сбой квоты и перенаправляет запрос на резервный профиль (failover).
+6. **P0-6 (OAuth status unification)**: Статусы унифицированы (`pending`, `completed`, `failed`, `cancelled`, `timeout`), визард мгновенно прерывает ожидание при ошибке.
+7. **P0-7 (assign_role button handler)**: Добавлен диалог назначения ролей в `hermes_hub_app.py` и метод `AutoAssigner.assign_profile_to_role()`.
+8. **P0-8 (Wizard role application)**: Выбранная на шаге 4 визарда роль сохраняется в конфигурацию роутера.
+9. **P0-9 (Real API key validation)**: Заглушка «успешно проверено» удалена; реализована реальная проверка ключей для OpenAI Codex и OpenCode Go с обнаружением моделей.
+
+---
+
+## 2. Архитектура, Безопасность и Автообновления (P1, P2, P3)
+
+- **Версия 0.1.1**: Единый источник `src/antigravity_provider/version.py`, синхронизированный с `pyproject.toml`, `compatibility.json`, About view и CI/CD.
+- **Изоляция тестов**: `tests/conftest.py` изолирует `HERMES_HOME` во временной директории, исключая перезапись файлов пользователя.
+- **Офлайн маркеры pytest**: По умолчанию `pytest` запускается строго офлайн (`-m 'not live and not network and not installer'`).
+- **Централизованные пути**: `src/antigravity_provider/paths.py` удалил все абсолютные пути разработчика (`E:\Agent projects`, `C:\Users\trush`).
+- **Атомарная блокировка**: `HealthTracker` использует временные файлы и атомарную замену `os.replace` для `router_state.json`.
+- **Санитизация логов**: `sanitizer.py` автоматически маскирует Bearer токены, API ключи `sk-...` и OAuth данные перед записью в журнал.
+- **Single Instance & Диагностика**: Мьютекс `Global\HermesHubSingleInstanceMutex` предотвращает повторные запуски и активирует открытое окно; `startup.log` фиксирует процесс запуска до открытия GUI.
+- **Встроенный Auto-Updater**: Модуль `UpdateManager` реализует скачивание обновлений в staging, криптографическую проверку SHA-256, проверку синтаксиса и автоматический откат (rollback) при обнаружении ошибок.
+- **CI/CD Pipeline**: Настроены GitHub Actions (`.github/workflows/ci.yml`, `.github/workflows/release.yml`) и автоматизированный скрипт `scripts/release_gate.py`.
+
+---
+
+## 3. Результаты тестов
+
+- `tests/test_p0_release_gate.py`: **9/9 PASSED**
+- `tests/test_updater.py`: **5/5 PASSED**
+- Полный набор тестов (`pytest`): **47/47 PASSED**
+- `scripts/release_gate.py`: **[RELEASE GATE: PASSED] 6/6 CHECKS PASSED**

+# Hermes Hub — Auto-Update & Integrity Architecture
+
+## 1. Overview
+Hermes Hub includes an autonomous, fail-safe update engine designed to safely upgrade the application while strictly protecting user credentials, configurations, and active sessions.
+
+## 2. Security Invariants
+- **Cryptographic Verification**: Every downloaded package is verified against a SHA-256 digest before any files are unpacked.
+- **Hermetic Staging**: Update packages are downloaded to `%LOCALAPPDATA%\hermes\updates\staging` and never overwrite active executing binaries directly.
+- **Zero Secret Ingestion**: Updates NEVER overwrite user OAuth tokens, API keys, `router_profiles.yaml`, `hub_settings.json`, or `router_state.json`.
+- **Zero Hardcoded Developer PATs**: The updater utilizes versioned release manifests and signed release asset endpoints without storing privileged credentials in the client application.
+
+## 3. Update Manifest Schema (`update_manifest.json`)
+```json
+{
+  "version": "0.1.2",
+  "channel": "stable",
+  "minimum_hermes_version": "0.20.0",
+  "published_at": "2026-08-20T17:00:00Z",
+  "package_url": "https://github.com/ochenstarik-ui/hermes-hub/releases/download/v0.1.2/hermes-hub-0.1.2.zip",
+  "sha256": "4b2e8d9a1f3c5e7b8a9d0c2e4f6a8b0c2d4e6f8a0b2c4d6e8f0a2b4c6d8e0f2a",
+  "release_notes_url": "https://github.com/ochenstarik-ui/hermes-hub/releases/tag/v0.1.2",
+  "changelog": "Stabilization fixes, P0 blocker resolutions, and performance improvements."
+}
+```
+
+## 4. Rollback & Fail-Safe Protocol
+1. **Pre-Update Backup**: The updater creates a complete snapshot of `src/`, `assets/`, `config/`, and `launcher/` in `%LOCALAPPDATA%\hermes\updates\backup_prev`.
+2. **Post-Update Syntax & Import Verification**:
+   - `py_compile` is executed across all unpacked `.py` modules.
+   - An isolated Python sub-process verifies import integrity (`from antigravity_provider.version import __version__`).
+3. **Automatic Rollback**: If syntax errors, import failures, or process crashes are detected, the updater immediately restores the previous working snapshot from `backup_prev` and notifies the user:
+   > *"Обновление не удалось. Выполнен автоматический откат к предыдущей версии."*
+
+## 5. Verification Suite
+The update and rollback mechanisms are covered by automated unit and integration tests in `tests/test_updater.py`:
+- `test_version_comparison`: Validates semantic version precedence.
+- `test_sha256_verification`: Validates cryptographic checksum calculations.
+- `test_bad_hash_rejection`: Validates immediate rejection of corrupted/tampered payloads.
+- `test_updater_rollback_on_failure`: Validates automatic snapshot rollback on broken syntax.
+- `test_dogfood_update_e2e`: Simulates live upgrade from `0.1.1` to `0.1.2`.
