Adapter Pattern

Each protocol is a separate Soroban contract that exposes the same interface. PositionRegistry only knows about adapters by protocol_id, so adding a new protocol is a deploy-and-register, not a redeploy of the registry.

PositionValue is a flat record per position holding { value: i128, is_debt: bool } in the accounting token's scale.

Trust Boundary

OracleRegistry is the single trust boundary for prices. Reflector's raw output is staleness-checked before any adapter sees it.
