Human inboxes run a baseline backfill after connection. You can trigger additional sync as needed.

## Trigger sync

```bash
POST /human/v0/inboxes/{inbox_id}/sync
```

## Backfill model

- Baseline backfill captures recent mailbox state during onboarding.
- Deeper enrichment consumes Deep Context credits according to your policy.
- Sync scheduling and retries are handled by the continuous worker.

## Operational tips

- Use routing subscriptions to consume events incrementally after baseline import.
- Track deep context usage in your usage dashboard before enabling large historical runs.

Human inbox sync supports baseline ingestion plus optional deeper historical enrichment.

## Trigger Sync

```bash
curl -X POST "$API_URL/human/v0/inboxes/{inbox_id}/sync" \
  -H "Authorization: Bearer $API_KEY"
```

## Backfill Modes

- Basic backfill: default account history sync.
- Deep backfill: enrichment-oriented history processing that consumes deep context credits.

## Operational Notes

- Sync jobs are processed by the continuous worker.
- Progress is visible through account sync state fields and downstream webhook events.
