- SELECT FOR UPDATE блокировка во всех 9 провайдерах (кроме YooKassa — свой паттерн)
- create_transaction(commit=False) + единый db.commit() для атомарности
- emit_transaction_side_effects() для отложенных событий после коммита
- Все link_*_payment_to_transaction используют db.flush() вместо db.commit()
- Freekassa/KassaAI: прямое присвоение transaction_id + flush вместо update_status
- MulenPay: прямая мутация balance_kopeks вместо add_user_balance
- Platega: блокировка перед чтением metadata, инлайн обновления полей
- CloudPayments: int(round(amount * 100)) для корректного округления
- Heleket добавлен в SUPPORTED_AUTO_CHECK_METHODS
- Удалены PII из логов yookassa webhook (заголовки, IP)
- UniqueConstraint(external_id, payment_method) на транзакциях + миграция 0017
- Cabinet: PaymentService(bot=bot) внутри try блока
- verify_payment_amount утилита для проверки суммы webhook
- Add ContextVarsMiddleware for automatic user_id/chat_id/username binding
via structlog contextvars (aiogram) and http_method/http_path (FastAPI)
- Use bound_contextvars() context manager instead of clear_contextvars()
to safely restore previous state instead of wiping all context
- Register ContextVarsMiddleware as outermost middleware (before GlobalError)
so all error logs include user context
- Replace structlog.get_logger() with structlog.get_logger(__name__) across
270 calls in 265 files for meaningful logger names
- Switch wrapper_class from BoundLogger to make_filtering_bound_logger()
for pre-processor level filtering (performance optimization)
- Migrate 1411 %-style positional arg logger calls to structlog kwargs
style across 161 files via AST script
- Migrate log_rotation_service.py from stdlib logging to structlog
- Add payment module prefixes to TelegramNotifierProcessor.IGNORED_LOGGER_PREFIXES
and ExcludePaymentFilter.PAYMENT_MODULES to prevent payment data leaking
to Telegram notifications and general log files
- Fix LoggingMiddleware: add from_user null-safety for channel posts,
switch time.time() to time.monotonic() for duration measurement
- Remove duplicate logger assignments in purchase.py, config.py,
inline.py, and admin/payments.py
- Add pyproject.toml with uv and ruff configuration
- Pin Python version to 3.13 via .python-version
- Add Makefile commands: lint, format, fix
- Apply ruff formatting to entire codebase
- Remove unused imports (base64 in yookassa/simple_subscription)
- Update .gitignore for new config files
