Bot handlers (H1-H5):
- confirm_extend_subscription: error alert instead of wrong sub fallback
- open_subscription_link/subscription_connect: startswith registration
- handle_subscription_settings: multi-tariff guard
- confirm_reset_traffic: FSM state check in multi-tariff
Services (H6-H12):
- subscription_service: 5 UUID fallback fixes — no user.remnawave_uuid in
multi-tariff, return None if subscription.remnawave_uuid missing
- auto_purchase: use cart subscription_id for tariff match
- remnawave_service: migrate_squad_users checks subscription.remnawave_uuid
- campaign_service: extend existing sub or create new in multi-tariff
- broadcast_service: check ALL subs for paid-subscription guard
- blocked_users_service: remnawave_uuids list, iterate in cleanup
- user_service: log sub.remnawave_uuid in multi-tariff
Admin (H13-H16):
- grant_trial/paid_subscription: allow in multi-tariff mode
- promo_offers: pick sub with URL, aggregate squads from all subs
CRUD/Frontend (H17-H18):
- get_users_list: .unique() for outerjoin dedup
- refreshTraffic: withSubId in params instead of body
- 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
