Changelog Entry

Description

Fixes a bug where calendar reminders configured as "At time of event" could be skipped when the scheduler polled slightly after the event start time.

Added

Grace window based on SCHEDULER_POLL_INTERVAL for exact-time reminder detection.

Changed

Updated calendar alert lookup logic to include recently-started events inside the scheduler polling window.

Deprecated

None

Removed

Fixed

"At time of event" reminders now trigger correctly for:
- UI notifications
- Webhook notifications

Security

Breaking Changes

Additional Information

Root cause:
get_upcoming_events() filtered only start_at >= now_ns, so if scheduler ran a few seconds late, the event was missed permanently.

Fix:
Allow a small backward grace window (now_ns - SCHEDULER_POLL_INTERVAL) during event lookup.
