LEG-001
Aveva Web API → Delmia DNC
Bidirectional orchestrated handshake. Harder retirement — requires ScadaBridge scripts to re-implement System Platform parse logic.
LEG-002
Aveva Web API ← Camstar MES
Camstar-initiated. Easier retirement — ScadaBridge already has a native Camstar path; requires Camstar-side reconfiguration.
LEG-003
System Platform → custom email notification service
Easier retirement — ScadaBridge native notifications already exist.
Carve-out: Historian MSSQL reporting surface (BOBJ / Power BI) is explicitly not legacy — see legacy-integrations.md → Deliberately not tracked.
