0010. Reminders run as a separate process¶

Status: Accepted, 2026-07-19 (#62); reason written down in #63

Context¶

The bot sends a reminder to learners who have gone quiet while something is due. That needs a loop running on a timer, independent of incoming updates.

Decision¶

Reminders run in their own process, python -m wiederholen.bot.reminder, as a separate service, rather than as an asyncio task inside the polling bot.

Alternatives considered¶

• A background task in the bot. One process fewer. Rejected because the bot's tests call main() repeatedly, and each call would leave an uncancelled background task running (#63).

Consequences¶

• The bot's startup and tests stay free of timers.
• One more service to run and configure; it needs the same storage variables as the bot.
• The reminder has no incoming updates, so it builds its own FSM context and opens its own spans (see Telegram bot, Tracing).
