| Control | State | What the evidence establishes |
|---|---|---|
| Account freeze | present | An authorized role can block addresses under the reviewed token transfer rules. |
| Pause | present | An authorized role can pause token transfers. Capability is separate from whether the token is currently paused. |
| Mint / burn | present | The implementation exposes mint/burn operations. Their authorization is scoped to the deployed contract and its configured roles or bridge. |
| Upgrade | present | A verified proxy/implementation upgrade entry point exists. The implementation pointer was read at the recorded block; authorization and delay must be inspected separately. |
| Administrator | present | Role-holder addresses were read from deployed state. See the role table; an address is not evidence of a person’s identity. |
| Governance | unknown | Not established for this deployed version. |
| Multisig | unknown | Not established for this deployed version. |
| Timelock | unknown | Not established for this deployed version. |
| Emergency bypass | unknown | Not established for this deployed version. |

Future accepted changes create new immutable records. The JSON export preserves this implementation, role state and assessment.
Contract powers do not establish issuer solvency, reserve quality, redemption eligibility or the identity of a key holder.
