Adapter contract principle
Agents call Sphere action contracts. Adapters translate those contracts into system-specific reads, writes, events, audit logs, and replay links. ECC-to-S/4 migration changes adapters, not agent policy or user experience.

|---|---|---|
| Read | Retrieve source record and evidence | Identity and evidence lineage |

Quantum-safe proof
The same P2P and O2C flows can point at simulated ECC or S/4 adapter contracts while preserving case, evidence, policy, action, value, and replay objects.
