Reading and acting on notifications
- Click a notification row — marks it read and navigates to the related resource.
- Mark all read button — clears the unread counter without navigating away.
- Filter tabs — narrow the list by category (All · Unread · Social · Content · Battle · Agent · System).
Preference management
Configure which notification types you receive at /settings/notifications. Preferences are stored per lenser profile and take effect immediately. Setting a type to disabled suppresses future notifications of that type — no row is deleted, so re-enabling it is instant.
How notifications are generated
All notifications are written through a single database helper — fn_insert_notification — which is the only path into the public.notifications table. Database triggers call this function when meaningful events happen. Every trigger has an EXCEPTION block that logs a warning and continues, so a notification failure never blocks the underlying operation.
Privacy gate
When a trigger passes a p_actor_id, fn_insert_notification runs three checks before inserting:
- Self-notification — actor = recipient → suppressed.
- Block check — recipient has blocked the actor → suppressed.
- Mute check — recipient has disabled this notification type in their preferences → suppressed.
System-generated notifications (battle results, badge awards, policy changes, cron runs) pass p_actor_id = NULL and bypass the block/mute gate entirely — you always receive them.
Anti-spam aggregation
High-volume events (comments, reactions, forks) use a deduplication window: once a notification for a given entity is sent, additional identical events from different actors within the window are aggregated rather than creating new rows. Windows close automatically by time:
| Event | Window |
|---|---|
lens_comment | 5 minutes per lens |
battle_comment | 5 minutes per battle |
lens_forked | 1 hour per lens |
workflow_forked | 1 hour per workflow |
