## Data Sync Considerations

- Initial sync returns 409 Conflict — wait and retry
- Recent app changes may not appear immediately
- Check `X-Last-Data-Change-At` header for freshness

## Rate Limit Handling

Watch for:
- `429 Too Many Requests` when exceeding 500/hour
- `X-RateLimit-Remaining` header
- Add `agentHints=true` for rate limit warnings
