Domain split

Privacy Pools and the Auditing Portal meet at the on-chain event boundary: 
PrivacyPoolsContract.transact -> AuditEncodedDigest -> scanner -> audit -> audit_interpretation
The privacy pool can execute on-chain transactions without the Audit UI being open. The Auditing Portal can index and manage disclosure workflows for registered contracts without being part of the end-user wallet flow.
