-## 31) Fire-and-forget reschedule may fail silently
-- Where found:
-	- [backend/app/tasks/blocklist_import.py](backend/app/tasks/blocklist_import.py#L108)
-- Why this is needed:

-- Goal:
-	- Make schedule updates deterministic and observable.
-- What to do:

-- Possible traps and issues:
-	- Blocking request path might add latency if scheduler is busy.
-- Docs changes needed:
-	- Document scheduling reliability guarantees.
-- Doc references:
-	- [Docs/Features.md](Docs/Features.md)
