master dac8e10e36 feat(crypto): Complete Phase 2 - Configuration-driven crypto architecture with 100% compliance 
## Summary

This commit completes Phase 2 of the configuration-driven crypto architecture, achieving
100% crypto compliance by eliminating all hardcoded cryptographic implementations.

## Key Changes

### Phase 1: Plugin Loader Infrastructure
- **Plugin Discovery System**: Created StellaOps.Cryptography.PluginLoader with manifest-based loading
- **Configuration Model**: Added CryptoPluginConfiguration with regional profiles support
- **Dependency Injection**: Extended DI to support plugin-based crypto provider registration
- **Regional Configs**: Created appsettings.crypto.{international,russia,eu,china}.yaml
- **CI Workflow**: Added .gitea/workflows/crypto-compliance.yml for audit enforcement

### Phase 2: Code Refactoring
- **API Extension**: Added ICryptoProvider.CreateEphemeralVerifier for verification-only scenarios
- **Plugin Implementation**: Created OfflineVerificationCryptoProvider with ephemeral verifier support
  - Supports ES256/384/512, RS256/384/512, PS256/384/512
  - SubjectPublicKeyInfo (SPKI) public key format
- **100% Compliance**: Refactored DsseVerifier to remove all BouncyCastle cryptographic usage
- **Unit Tests**: Created OfflineVerificationProviderTests with 39 passing tests
- **Documentation**: Created comprehensive security guide at docs/security/offline-verification-crypto-provider.md
- **Audit Infrastructure**: Created scripts/audit-crypto-usage.ps1 for static analysis

### Testing Infrastructure (TestKit)
- **Determinism Gate**: Created DeterminismGate for reproducibility validation
- **Test Fixtures**: Added PostgresFixture and ValkeyFixture using Testcontainers
- **Traits System**: Implemented test lane attributes for parallel CI execution
- **JSON Assertions**: Added CanonicalJsonAssert for deterministic JSON comparisons
- **Test Lanes**: Created test-lanes.yml workflow for parallel test execution

### Documentation
- **Architecture**: Created CRYPTO_CONFIGURATION_DRIVEN_ARCHITECTURE.md master plan
- **Sprint Tracking**: Created SPRINT_1000_0007_0002_crypto_refactoring.md (COMPLETE)
- **API Documentation**: Updated docs2/cli/crypto-plugins.md and crypto.md
- **Testing Strategy**: Created testing strategy documents in docs/implplan/SPRINT_5100_0007_*

## Compliance & Testing

- ✅ Zero direct System.Security.Cryptography usage in production code
- ✅ All crypto operations go through ICryptoProvider abstraction
- ✅ 39/39 unit tests passing for OfflineVerificationCryptoProvider
- ✅ Build successful (AirGap, Crypto plugin, DI infrastructure)
- ✅ Audit script validates crypto boundaries

## Files Modified

**Core Crypto Infrastructure:**
- src/__Libraries/StellaOps.Cryptography/CryptoProvider.cs (API extension)
- src/__Libraries/StellaOps.Cryptography/CryptoSigningKey.cs (verification-only constructor)
- src/__Libraries/StellaOps.Cryptography/EcdsaSigner.cs (fixed ephemeral verifier)

**Plugin Implementation:**
- src/__Libraries/StellaOps.Cryptography.Plugin.OfflineVerification/ (new)
- src/__Libraries/StellaOps.Cryptography.PluginLoader/ (new)

**Production Code Refactoring:**
- src/AirGap/StellaOps.AirGap.Importer/Validation/DsseVerifier.cs (100% compliant)

**Tests:**
- src/__Libraries/__Tests/StellaOps.Cryptography.Plugin.OfflineVerification.Tests/ (new, 39 tests)
- src/__Libraries/__Tests/StellaOps.Cryptography.PluginLoader.Tests/ (new)

**Configuration:**
- etc/crypto-plugins-manifest.json (plugin registry)
- etc/appsettings.crypto.*.yaml (regional profiles)

**Documentation:**
- docs/security/offline-verification-crypto-provider.md (600+ lines)
- docs/implplan/CRYPTO_CONFIGURATION_DRIVEN_ARCHITECTURE.md (master plan)
- docs/implplan/SPRINT_1000_0007_0002_crypto_refactoring.md (Phase 2 complete)

## Next Steps

Phase 3: Docker & CI/CD Integration
- Create multi-stage Dockerfiles with all plugins
- Build regional Docker Compose files
- Implement runtime configuration selection
- Add deployment validation scripts

Advisory architecture alignment

Purpose

  • Summarize alignment with advisory architecture requirements.
  • Capture supported formats, evidence types, and known gaps.

DSSE predicate types

  • https://in-toto.io/attestation/slsa/v1.0 (Attestor)
  • stella.ops/sbom@v1 (Scanner)
  • stella.ops/vex@v1 (Excititor)
  • stella.ops/callgraph@v1 (Scanner.Reachability)
  • stella.ops/reachabilityWitness@v1 (Scanner.Reachability)
  • stella.ops/policy-decision@v1 (Policy.Engine)
  • stella.ops/score-attestation@v1 (Policy.Scoring)
  • stella.ops/witness@v1 (Scanner.Reachability)
  • stella.ops/drift@v1 (Scanner.ReachabilityDrift)
  • stella.ops/unknown@v1 (Scanner.Unknowns)
  • stella.ops/triage@v1 (Scanner.Triage)
  • stella.ops/vuln-surface@v1 (Scanner.VulnSurfaces)
  • stella.ops/trigger@v1 (Scanner.VulnSurfaces)
  • stella.ops/explanation@v1 (Scanner.Reachability)
  • stella.ops/boundary@v1 (Scanner.SmartDiff)
  • stella.ops/evidence@v1 (Scanner.SmartDiff)
  • stella.ops/approval@v1 (Policy.Engine)
  • stella.ops/component@v1 (Scanner.Emit)
  • stella.ops/richgraph@v1 (Scanner.Reachability)

VEX and advisory formats

  • OpenVEX 0.2.0+
  • CycloneDX VEX 1.4 to 1.6
  • CSAF 2.0
  • OSV

CVSS and scoring

  • CVSS v4 vector parsing with macrovector and environmental metrics.
  • Deterministic scoring with canonical JSON, stable ordering, and hashed snapshots.

EPSS handling

  • EPSS uses model_date (daily) rather than numbered versions.
  • Scores and percentiles are stored with model_date and captured at scan time.
  • Offline bundles include EPSS data and hashes for air-gapped replay.

Reachability analysis

  • Hybrid static and runtime reachability evidence.
  • Call graph extraction for .NET, Java, Node.js, Python, Go (external tooling), and native binaries.

Call-stack witnesses

  • Signed witnesses for entrypoint-to-sink paths.
  • Witnesses are stored as content-addressed artifacts with DSSE signatures.

Smart-diff rules

  • New finding detection.
  • Score increase detection.
  • VEX status change detection.
  • Reachability change detection.

Unknowns handling

  • Unknown types: missing_vex, ambiguous_indirect_call, unanalyzed_dependency, stale_sbom, missing_reachability, unmatched_cpe, conflict_vex, native_code, generated_code, dynamic_dispatch, external_boundary.
  • Scoring dimensions: blast radius, evidence scarcity, exploit pressure, containment signals, time decay.

CycloneDX baseline

  • Current baseline is CycloneDX 1.6; upgrade to 1.7 when SDK support is available.

Areas beyond baseline requirements

  • Offline and air-gap operation with bundled proofs.
  • Regional crypto readiness (GOST, SM2/SM3, PQ-ready modes).
  • Multi-tenant isolation and signed transparency integration.
  • Native binary analysis for PE, ELF, and Mach-O.
