- Multi-channel subscription enforcement via middleware, events, and cabinet API
- 3-layer cache architecture: Redis -> PostgreSQL -> rate-limited Telegram API
- ChatMemberUpdated event-driven tracking with automatic VPN access control
- Admin management via bot FSM handler and REST API with full CRUD
- Channel ID normalization: @username resolved to numeric ID at creation time
- Fail-closed error handling: API errors deny access (security-first)
- Background reconciliation with keyset pagination (100 per batch)
- Per-user rate limiting on subscription check button (5s cooldown)
- Redis connection pooling via cache singleton (no per-request connections)
- Database: channel_id index, multi-row upsert optimization
- Localization: en, ru, zh, fa, ua translations for all new strings
- Frontend blocking UI with channel list and subscription status
- Admin channel management page with toggle, delete, and create
- 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
- Wrap unprotected add/remove_user_to/from_servers calls in try/except
in miniapp.py and cabinet subscription.py to prevent 500 errors
- Fix is_tariff_change to include classic-to-tariff transitions
(subscription.tariff_id=None → new tariff_id) so purchased traffic
is properly reset when switching modes
New setting allows granular control over trial availability:
- none: trial available for all (default)
- email: trial disabled for email users
- telegram: trial disabled for telegram users
- all: trial disabled for everyone
Enforced in bot handlers, cabinet API, and miniapp routes.
