DescriptorMismatch

The descriptor does not match the account's permanent authorization record. Check the destination and exported public descriptor; re-registration cannot reset keys.

Declared by the HashedAccounts pallet; it classifies to the semantic code invalid_argument.

Declared at pallets/hashed-accounts/src/lib.rs#L263.

Remediation
