Your wallet should remember your choice.
The production router now supports explicit choice, a saved wallet preference, ordered fallback tenders, and capability-aware fallback. Durable preferences are only written after CHLOM can bind the wallet to an exact DID + Fingerprint identity record.
DID + Fingerprint binding establishes the wallet subject.
Selective-disclosure mode can require a verified ZK proof receipt when a real verifier circuit is present.
Customer choice outranks saved preference, which outranks deterministic fallback.
ECAC and provider capability are rechecked before any economic action.
