The sync engine maps fields intelligently: Jira issue types to Notion select properties, Linear priority levels to Notion status groups, GitHub labels to Notion multi-select tags, and assignees to Notion people properties via email matching. It handles rich content synchronization including Markdown-to-Notion block conversion for descriptions, comment threading with attribution, and attachment linking.

Conflict resolution follows configurable strategies: last-write-wins, source-of-truth per field, or manual review queue for contested changes. The agent supports filtered sync rules (e.g., only sync epics from Jira, only sync high-priority Linear issues) and transformation pipelines that can enrich data during sync (adding team labels, calculating derived fields). It logs all sync operations to a dedicated Notion audit database and can generate weekly sync health reports with error rates, latency metrics, and data consistency scores.
