Cardinality
One document header carries many lines. Every line resolves to exactly one cost center and one GL account. A line is never split across cost centers.
Write-back rule
Park only, never post. The connector may create a parked journal and attach the agent authority reference; the posting itself stays with a qualified accountant inside the source application.
Review state
Neither review is performed by the team that wrote the contract.
