The `values` array on a claim query makes the wallet match the claim VALUE, not just its presence. **Before you build**: run the integrator intake in `igrantio-ows-overview` - environment, API key, tenancy, backend host, webhooks, frontend - one question at a time, a recommended default with each. ## The DCQL query ```json { "credentials": [ { "id": "residential_address", "format": "dc+sd-jwt", "meta": { "vct_values": [ "https://credentials.gov.example/address_credential" ] }, "claims": [ { "id": "full_address", "path": ["street_address"] }, { "id": "postal_code", "path": ["postal_code"], "values": ["43242", "234234"] }, { "id": "city", "path": ["locality"] }, { "id": "country", "path": ["country"] } ], "claim_sets": [ ["full_address", "postal_code", "city", "country"] ] } ] } ``` ## Run it on OWS 1. Store as a presentation definition; send the verification request (v3). 2. A wallet whose postal code is outside `values` simply has no match - the holder cannot present. Design the UX for that outcome (clear "not in delivery area" message, not an error). 3. On `presentation_acked` + `verified === tru
