 The enrichment worker creates `PRECEDED_BY` relationships to recent memories within a time window:
 
 - **Trigger:** Every enriched memory
-- **Target:** Memories from the last 24 hours (configurable)
+- **Target:** Memories from the last 7 days
 - **Direction:** New memory → Older memory
-- **Properties:** `time_gap` (seconds between memories)
+- **Properties:** `count` (incremented each time the edge is updated), `updated_at` (ISO timestamp)
 
 **Purpose:** Maintains conversation flow and temporal context for recall.
