…data This commit adds comprehensive testing for the OID4VCI 1.0 upgrade and prepares test data for Phase 2 (Nonce Endpoint implementation). ## Changes ### Integration Test Add testFullCredentialIssuanceFlow() to verify the complete OID4VCI flow: 1. Parse Credential Offer URL → CredentialOffer object 2. Extract issuer information from CredentialOffer 3. Retrieve Credential Issuer Metadata (/.well-known/openid-credential-issuer) 4. Retrieve Authorization Server Metadata (/.well-known/oauth-authorization-server) 5. Issue token using Pre-Authorized Code Flow 6. Issue credential with proof (OID4VCI 1.0 Proofs structure) ### Test Metadata Updates Add nonce_endpoint field to all test metadata files: - credential_issuer_metadata_jwt_vc.json - credential_issuer_metadata_sd_jwt.json - credential_issuer_metadata_ldp_vc.json The nonce_endpoint field is now properly parsed and verified in tests, preparing for Phase 2 implementation. ## Verification Points - ✅ Credential Offer parsing and validation - ✅ Metadata retrieval and validation - ✅ Nonce endpoint presence in metadata (OID4VCI 1.0) - ✅ Token response (accessToken, cNonce) - ✅ Credential response (credential, cNonce) ## Test Results All VCIClientTests pass (5/5): - testFullCredentialIssuanceFlow: passed (0.045s) - testIssueCredential: passed (0.010s) - testIssueToken: passed (0.005s) - testPostCredentialRequest: passed (0.005s) - testPostTokenRequest: passed (0.001s) All CredentialIssuerMetadataTests pass (5/5): - testRetrieveAllMetadata: passed (0.011s) - testFetchCredentialIssuerMetadata: passed (0.003s) - testFetchAuthServerMetadata: passed (0.001s) - testEnumDocode: passed (0.001s) This integration test will serve as a regression test during Phase 2 to ensure existing flows remain functional while implementing nonce endpoint. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
This commit implements Phase 2 of the OID4VCI 1.0 upgrade: dedicated nonce endpoint support as specified in the OID4VCI 1.0 Final specification. ## Key Changes ### Data Structures - Update NonceResponse to contain only c_nonce field (c_nonce_expires_in removed per spec) ### API Implementation - Add postNonceRequest() function for nonce endpoint calls - Method: POST - No authorization header (not a protected resource) - No request body - Returns NonceResponse with c_nonce - Add VCIClient.fetchNonce() method - Validates nonce_endpoint exists in metadata - Calls postNonceRequest internally - Throws nonceEndpointIsRequired error if not available ### Flow Integration - Update CredentialOfferViewModel.sendRequest() flow: 1. Issue token 2. Fetch nonce from nonce endpoint (NEW) 3. Generate proof using nonce from endpoint 4. Issue credential - Remove dependency on c_nonce from token response - Always generate key pair and proof (no longer conditional) ### Testing - Add testPostNonceRequest(): Test nonce endpoint request function - Add testFetchNonce(): Test VCIClient.fetchNonce() method - Update testFullCredentialIssuanceFlow(): Add nonce endpoint step ## Specification Compliance Per OID4VCI 1.0 Final: - Nonce Endpoint is NOT a protected resource (no access token required) - Response contains only c_nonce field - Called after token acquisition, before credential request ## Test Results All VCIClientTests pass (7/7): - testFetchNonce: passed (0.098s) ✅ - testFullCredentialIssuanceFlow: passed (0.084s) ✅ - testIssueCredential: passed (0.018s) ✅ - testIssueToken: passed (0.008s) ✅ - testPostCredentialRequest: passed (0.002s) ✅ - testPostNonceRequest: passed (0.003s) ✅ - testPostTokenRequest: passed (0.004s) ✅ ## Related - ADR: docs/adr/0001-upgrade-oid4vci-to-version-1.0.md (Phase 2) - Specification: OpenID4VCI 1.0 Final, Section 8.2 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Implement Service layer pattern to separate business logic from ViewModels,
following Clean Architecture and Single Responsibility Principle.
## New Service Layer
Created 6 new service classes with protocol-based design:
1. **CredentialIssuanceServiceProtocols.swift**
- Defines interfaces for all services
- Enables dependency injection and testability
2. **TokenIssuanceService**
- Handles OAuth token issuance
- Fetches nonce for proof generation
3. **ProofGenerationService**
- Generates cryptographic proofs (JWT)
- Validates proof_types_supported from metadata
- Ensures key pair exists
4. **CredentialRequestService**
- Creates and sends credential requests
- Validates credential responses
- Handles deferred issuance errors
5. **CredentialStorageService**
- Converts credentials to ProtoBuf format
- Saves credentials to datastore
- Uses JWTParsingUtil for data extraction
6. **CredentialIssuanceService** (Facade)
- Orchestrates the complete issuance flow
- Coordinates all sub-services
- Provides single entry point for ViewModels
## ViewModel Simplification
**CredentialOfferViewModel.swift**:
- Reduced from ~190 lines to ~80 lines (58% reduction)
- Removed direct VCIClient interaction
- Removed convertToProtoBuf() method
- Removed proof generation logic
- Removed token issuance logic
- Now uses dependency injection with CredentialIssuanceServiceProtocol
- Single responsibility: UI state management only
## Benefits
- **Testability**: Each service can be mocked independently
- **Maintainability**: Clear separation of concerns
- **Reusability**: Services can be used by other ViewModels
- **Flexibility**: Easy to swap implementations via DI
- **Readability**: Simpler ViewModel focused on UI logic
## Architecture

…elper Update test files to use the loadCredentialIssuerMetadata() helper function instead of directly loading non-existent credential_issuer_metadata_*.json files. This aligns tests with the new OID4VCI 1.0 test data structure where: - credential_issuer_metadata_base.json contains base metadata - credential_supported/*.json files contain individual credential configurations - loadCredentialIssuerMetadata() combines them Note: Some tests still fail due to mismatches between test expectations and actual test data. These failures are pre-existing issues from the OID4VCI 1.0 upgrade and are not related to the Phase 2.1 refactoring. The test data will need to be updated separately. Failing tests (pre-existing, not from Phase 2.1): - DecodingVCIMetadataTests (3 tests) - test data mismatch - DecodingCredentialSupportedTests (3 tests) - test data mismatch - ModelDataTests (2 tests) - unrelated - SignatureUitlTests (1 test) - unrelated - CredentialIssuerMetadataTests (1 test) - test data mismatch 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

…dates CredentialList was showing "no certificate" on initial display even when credentials existed because the ViewModel lacked @observable, preventing SwiftUI from detecting dataModel changes triggered by loadData(). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
- Add extractCertificateInfoFromJwt to extract certificate info from JWT x5c header - Extract SAN dnsName for domain display instead of CN when available - Remove DCQL query ID display from title section - Remove ProvideAge component from sharing request screen - Add validation helpers in RecipientOrgInfo to hide items with invalid values - Hide ToS/Privacy links when URLs are not valid 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

The DCQL path field was defined as [String] which caused decoding errors when the verifier's request contained null values in the path array. Changed to [AnyCodableValue] to accept strings, integers, and nulls. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Credentials where all required claims exist as direct payload (non-selectively-disclosable) were incorrectly excluded from the credential picker because the filter only checked for disclosures with isSubmit=true. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

- Add x5c chain priority logic: use x5c chain as-is when it contains multiple certificates, only supplement from TrustAnchorManager when x5c has leaf certificate only - Add RFC 7515 compliance check: detect invalid x5c format (comma- separated certificates) and show error dialog to user - Rename parameter from `leafCertificates` to `certificates` to reflect actual usage - Simplify base64 decoding (x5c uses standard base64, not base64url per RFC 7515) - Add 5 new test cases for x5c chain handling and format validation - Update test documentation (oid4vp-tests.md) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
