|---|---|---|---|---|---|
| DETAIL_EVENT_ID | NUMBER | 18 | Yes | Synthetic primary key for an appended detail event. | |
| LOGICAL_ID | VARCHAR2 | 4000 | Yes | Stable Timelines logical identifier for this detail event. | |
| LOGICAL_ID_HASH | RAW | 32 | Yes | SHA-256 hash of LOGICAL_ID for indexed detail-event lookup and uniqueness. | |
| TIMELINE_ID | NUMBER | 18 | Yes | Owning timeline identifier for ordered replay. | |
| CORRELATION_SET_ID | NUMBER | 18 | Reusable correlation bundle selected for this event. | ||
