- trial подписки теперь конвертируются в платные вместо отказа (ошибка ~20 из 300 юзеров)
- extend_subscription: добавлен переход TRIAL→ACTIVE
- UniqueConstraint на PromoCodeUse(user_id, promocode_id) + миграция 0015 с дедупликацией
- create_promocode_use: begin_nested()+flush() вместо commit/rollback (без коррупции сессии)
- race condition: create_promocode_use вызывается ДО _apply_promocode_effects
- cleanup: удаление зарезервированной записи при ValueError от эффектов
- atomic SQL increment для current_uses (защита от lost-update)
- mark_user_as_had_paid_subscription: savepoint вместо commit/rollback
- удалён мёртвый код: use_promocode(), trial_subscription_not_eligible из маппингов
- Fix balance history display: referral_reward, refund, poll_reward now
shown as credits (💰 +amount) instead of expenses
- Fix double-counting: remove all Transaction-based REFERRAL_REWARD sum
queries from crud/referral.py, admin_stats.py, admin_users.py —
ReferralEarning is now the single source of truth
- Unify "active referrals" definition across cabinet, bot, and admin:
JOIN Subscription WHERE status=ACTIVE AND end_date > now()
- Add payment_method IS NOT NULL guard to get_user_own_deposits() to
exclude referral rewards historically mistyped as deposits
- Replace hardcoded transaction type strings with TransactionType enum
values in referral_withdrawal_service.py
- Add Alembic data migration (0014) to fix historical transactions:
UPDATE deposit → referral_reward WHERE payment_method IS NULL and
description matches referral patterns
- 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
