# Session 0010: Sync Router Bidirectional Fix

**Date:** 2026-02-25
**Status:** Completed
**Origin:** MDF Webseiten session 0052

## Work Done

- [x] Fixed `sync_data.py` — added bidirectional sync pairs (int->prod, dev->int); was only defined in one direction → caused "Connection lost" error when triggering int->prod sync from dashboard

## Key Decisions / Learnings

- Sync pairs must be defined bidirectionally in the router even if data only ever flows one direction (prod→int→dev) — the UI may call either direction depending on user intent
- This was a trivial fix but caused a visible "Connection lost" failure in the dashboard
