   - Документация: `doc/src.utils.config_manager.md`, `src/utils/config_manager/AGENTS.md`
 - [x] Создан `requirements.txt`
 - [x] Опубликован на https://git.komisar.gin.by/komisar/komAI
+- [x] Реализован модуль `src/utils/log_manager` для логирования
+  - `LoggerPrint` с методом `print()` для консоли и файла
+  - `LogManager` с фабрикой обработчиков и ротацией
+  - Константы для конфига (`LOG_CATEGORY`, `LOG_CONSOLE`, etc.)
+  - 9/9 тестов проходят
+  - Документация: `src/utils/log_manager/AGENTS.md`
 
 ## In Progress
 
 ## Pending
 
-- [ ] Реализовать модуль логирования
-  - [ ] stdout/stderr перехват при аварийном завершении (on crash)
+- [ ] stdout/stderr перехват при аварийном завершении (on crash)
 - [ ] Создать приложение `app/komAI.py` как точку входа
 - [ ] Реализовать систему модулей (`modules/`)
 - [ ] Настроить CI/CD
