 The protocol supports binding additional application-specific data to TEE attestations through the `extendedRegistrationData` field. This enables applications to attest to configuration, public keys, or other data alongside the TEE identity.

 1. **TEE-controlled address**: The address extracted from the quote's report data field ([TDReport.ReportData](#tdreport)), whose private key was generated inside the TEE and is used to interact with onchain contracts.

 ## Policy Layer: Flexible Authorization

+The Policy layer sits above the Flashtestation Registry and provides a more flexible authorization mechanism. It's realized by Policy contracts, possibly using the same registry.
 
 ### Policy Abstraction
 
-A Policy is simply a named authorization mapping of addresses, implemented through a mapping of TEE registration data for the address and governable WorkloadIds.
+A Policy is simply a contract authorizing addresses through allowlisting WorkloadIds derived from TEE registration data.
 
 ```
 Policy: [teeAddress -> **`RegisteredTEE`**] -> [**`RegisteredTEE`** -> **`WorkloadId`**] -> [**`WorkloadId`** -> bool]
 ```
 
-This abstraction allows contracts to reference a policy (e.g., "L2-BlockBuilding-Production") rather than specific workloads, enabling governance to update which workloads are acceptable without modifying contract code.
+This allows downstream contracts and products to reference a policy contract by address rather than managing specific workloads.
