# Move larger historical slices into your warehouse or object store workflow.

S3 archive export is for historical backfills from Synorb's temporal context graph. REST and MCP serve the live window: the current calendar month plus the previous three full months. As each month ages out, it rolls into S3 archive storage for approved backfill access.

## Export Structure

Archive exports are organized by stream and calendar month, with separate JSONL files for records, signals, and briefs.

```
exports/streams/{stream_id}/2026-01/
  records.jsonl
  signals.jsonl
  briefs.jsonl
```
